    AbstractThe dimensionality of coping, as measured by 65 items from 3 commonly used instruments, and the relation of

    coping and stress to concurrent and future depression were studied in a community sample of 742 older (>=50 years

    old) adults. Measures of coping, stress, and depression were obtained at 2 time points over a 2-year period.

    Depression was assessed by symptom checklist and by diagnostic interview. Three coping factorsCognitive

    Self-Control, Ineffective Escapism, and Solace Seekingthat had adequate psychometric properties and accounted for

    25% of the total item variance were identified. Ineffective Escapism was associated with current depression and had adirect and interactive effect on future depression, exacerbating the negative impact of stress rather than acting as a

    buffer. Although Cognitive Self-Control was unrelated to either concurrent or future depression, Solace Seeking

    significantly buffered the effect of stress in predicting a future diagnosis of depression. Stress and initial depression

    level predicted both measures of future depression. Gender (being female) predicted the future diagnosis of

    depression but not the increase of depressive symptoms.

    In the last decade, the construct labeled coping has received considerable attention in the psychological

    literature (e.g., Billings & Moos, 1981; Folkman & Lazarus, 1980; Lazarus, 1981; Pearlin & Schooler, 1978), most

    frequently as a factor that mediates the relation between stress and physical or mental disorder. Although numerousstudies have reported a significant relation between stress and illness (e.g., Antonovsky, 1979; F. Cohen & Lazarus,

    1979; B. P. Dohrenwend, 1979; Johnson & Sarason, 1978; Rabkin & Streuning, 1976) and more specifically, between

    stress and depression (Billings & Moos, 1982, 1984; B. S. Dohrenwend & Dohrenwend, 1981; Folkman & Lazarus, 1986;

    Paykel, 1979), the predictive ability of stress on future disorder has generally been quite modest. Thus, the hypothesis

    that coping is a mediator variable between stress and disorder is attractive, because it potentially explains the

    persistent and theoretically troubling low magnitude of association between stress and disorder. It is hypothesized

    that, given the same degree of stress, people who use more effective coping strategies will experience less disrupted

    behavior and subsequently will experience less distress. An extensive literature has attempted to address this question

    with mixed, often positive, results (e.g., Aldwin & Revenson, 1987; Mitchell, Billings, & Moos, 1982; Mitchell,

    Cronkite, & Moos, 1983; Pearlin, Lieberman, Menagham, & Mullan, 1981).

    In addition to the term coping, a number of conceptually similar constructssuch as competence(Goldfried &

    D'Zurilla, 1969),problem-solving ability(D'Zurilla & Nezu, 1982; Heppner & Peterson, 1982), hardiness(Kobasa, 1979),

    antidepressive behaviors(Rippere, 1976), and learned resourcefulness(Meichenbaum, 1977; Rosenbaum, 1980)have

    also been introduced. As may be assumed from the variety of terms in this area, little agreement exists regarding the

    optimal conceptualization of coping. Although many issues are still being actively debated, these terms have been

    used by and large to describe behavioral and cognitive patterns used by people in the face of difficult and problematic

    situations and will be considered in this article to represent the general domain of coping.

    Although several interview protocols have been developed to measure coping (e.g., Brown & Harris, 1978;

    Folkman & Lazarus, 1986), it most often has been measured with self-report questionnaires, such as the ProblemSolving Inventory (Heppner & Peterson, 1982), the Ways of Coping Questionnaire (Folkman & Lazarus, 1980), the

    Self-Control Scale (Rosenbaum, 1980), the Coping Strategies Inventory (Tobin, Holroyd, & Reynolds, 1982), and the

    MeansEnds Problem-Solving Procedure (Platt & Spivack, 1975). Although some effort has gone into verifying the

    validity of these coping measures, such as the Self-Control Scale (Courey, Feuerstein, & Bush, 1982; Frankel &

    Merbaum, 1982; Rosenbaum 1980; Rosenbaum & Rolnick, 1983), it may be suggested that in general, more effort is

    needed to establish the construct validity of the numerous coping measures. In addition, the degree to which these

    instruments measure the same underlying construct has received little study. An important assumption of the present

    investigation is that many of the currently available instruments are indeed measures of a single underlying construct

    (which may have several dimensions) and therefore that the combined use of items from various measures would

    facilitate the assessment of the coping construct. In summary, although several self-report instruments have been

    developed, numerous questions remain regarding the optimal measurement of coping.

    In spite of the unidimensionality implied by the term coping, researchers have recognized the potential factors of

    this construct and have subsequently proposed various dimensions of coping. Several classifications of the

    distinguishing factors or dimensions of coping have been suggested on theoretical grounds, such as problem-focused

    versus emotion-focused coping (Lazarus & Folkman, 1984) and approach versus avoidance coping (Roth & Cohen, 1986;

    Suls & Fletcher, 1985). For instance, Billings and Moos (1982)distinguished between appraisal-focused coping (e.g.,

    reminding oneself that things could be worse), problem-focused coping (e.g., destroying an alcoholic spouse's liquor

    supply), and emotion-focused coping (e.g., meditating). A second approach, which generally has used factor-analytic

    procedures, addresses the issue of dimensionality on more empirical grounds (e.g., Aldwin & Revenson, 1987;

    Folkman, Lazarus, Dunkel-Schetter, DeLongis, & Gruen, 1986; Frank et al., 1987). Using factor analysis, Parker and

    Brown (1982)identified six coping factors, which they labeled Recklessness(e.g., break things), Socialization(e.g.,spend time with friends), Distraction(e.g., busy oneself with work), Problem Solving(e.g., think through the

    problem), Passivity(e.g., read), and Self-Consolation(e.g., spend money on oneself). Thus, in addition to the role of

    coping as a mediator of stress on disorder, the dimensionality and specific nature of coping clearly deserve attention.

    Clarifying the dimensionality of coping is important in developing a better understanding of what people do under

    stressful conditions. The most parsimonious assumption, perhaps, is that coping can be represented best as a single

    factor. If that were the case, the mediator hypothesis would predict that people strong on this single factor would be

    less affected by stressful events. On the other hand, if, as suggested by many, coping were best represented by more

    than one dimension, the picture would become more complicated. In this second scenario, the various coping

    dimensions might well differ in their relation between stress and disorder, with some dimensions having a strong

    mediator role and others being irrelevant to that association. Such distinctions, if they exist, would greatly clarify ourtheoretical understanding of the relation between stress and disorder and would be useful in developing clinical

    interventions for use by individuals in high-stress situations.

    As with the construct coping, many questions remain in the conceptualization and measurement of stress.

    Although stress was measured initially primarily by life-change event scales (e.g., Holmes & Rahe, 1967), a number of

    concepts such as daily hassles(Kanner, Coyne, Schaefer, & Lazarus, 1981), life strains(Pearlin & Schooler, 1978), and

    microstressors(McLean, 1976; Monroe, 1983) have been used in attempting to assess ongoing strains and everyday

    frustrations, in addition to major life events. The measurement of both discrete stressful events and ongoing strains

    might provide the most comprehensive measure of stress. In addition, one increasing concern is the potential

    confound between concurrent measures of stress and measures of psychological distress (B. S. Dohrenwend,Dohrenwend, Dobson, & Shrout, 1984; Lazarus, DeLongis, Folkman, & Gruen, 1985; Lloyd & Lishman, 1975).

    Dohrenwend and colleagues (B. S. Dohrenwend et al., 1984) reported that several measures of stress assess not only

    stressful events but also psychopathology, thus confounding a dependent variable (stress) with an independent

    variable (psychological symptoms). In their review of this literature, Lazarus and his colleagues (Lazarus et al., 1985)

    concluded that although some of the fusion between measures of stress and psychopathology most likely reflects the

    true nature of these constructs, a longitudinal approach is required to clarify any temporal relation between stress

    and disorder.

    In regard to depression, we expected that individuals who reported more effective coping behaviors would

    function more effectively and experience fewer depressive episodes. Several studies have reported that depressed

    and nondepressed individuals differ in the frequency and types of coping behaviors they use. For example, depressedindividuals are reported to use less problem solving and more emotional discharge (Billings & Moos, 1984), wishful

    thinking, avoidance, and emotional support seeking (Coyne, Aldwin, & Lazarus, 1981). Because of the potential

    confound among concurrent measures of stress, coping, and depression, we were particularly interested in the ability

    of stress and coping to predict future depression. Lewinsohn and Alexander (1983)found that scores on the

    Self-Control Scale (a measure of learned resourcefulness; Rosenbaum, 1980) predicted future occurrence of

    depression. People who reported low levels of learned resourcefulness and who were not depressed at the first

    observation were more likely to develop an episode of depression at a later point during the course of the study.

    Interestingly, in that study, learned resourcefulness had a direct impact on future depression; that is, this measure of

    coping predicted a person's becoming depressed independent of his or her reported level of stress. In conclusion, we

    expected that poor coping would be associated both with current depression and with the future occurrence of

    depression in a nondepressed group.

    The Present StudyThe present study is an attempt to address several of the previously mentioned issues. As part of a longitudinal,

    prospective study aimed at the identification of risk factors for nonbipolar depression in the elderly (Lewinsohn,

    Tilson, Rohde, & Seeley, 1988), 65 items assembled from three commonly used coping instruments were administered

    to a cohort of 742 persons who were 50 years of age or older at two points of time (T1 and T2) over approximately a

    2-year period. In addition to the assessment of coping, measures of demographic and stress variables were gathered (a

    variety of other measures were also assessed but are not presented in the current report). Stress was assessed both by

    major life events and by daily hassles. The presence of depression was assessed by a self-report questionnaire and a

    diagnostic interview at T1 and T2 and at an intermediate casefinding phase (post-T1) of the study. On the basis of

    diagnostic criteria, 96 subjects were judged to be depressed at T1, and 139 subjects were identified who, althoughnot clinically depressed at T1, developed a depressive episode during the course of the study. We referred to the

    latter as Cases.

    With this data set, we were able to examine a number of important questions. First, we used factoring procedures

    to explore the dimensionality of coping as measured by the 65 items. Second, we examined the relation of coping (as

    measured both by the original scales and by newly developed factors) with demographic variables and concurrent

    depression. Third, because of the longitudinal design of the study, we were able to investigate the direct versus

    interactive effects of coping and stress in predicting the future occurrence of depression.

    Method

    ParticipantsSubjects were recruited between May 1982 and November 1983 through announcements inviting participation in

    psychological research. A total of 4,133 individuals over the age of 50 residing in EugeneSpringfield, Oregon (N=

    34,633) were randomly selected from a list of licensed drivers and were sent a letter that described the general nature

    of the study (i.e., psychological research regarding life satisfaction, health, and aging) and that informed them that

    they would be telephoned and given further information. Follow-up phone calls were made within 2 weeks of the date

    of the original mailing, to a randomly selected sample of 2,662. Of those called, 259 (9.7%) either were ill or had

    moved out of the area, 849 (31.9%) declined to participate, and 1,554 (58.4%) agreed to participate in the study.

    Those who agreed to participate were asked to complete an extensive self-report questionnaire and come to the

    University of Oregon Psychology Clinic for a diagnostic interview within 2 weeks of returning the questionnaire. A

    total of 1,008 subjects completed both procedures. (The remaining 546 chose to complete either the questionnaire orthe interview, and we do not discuss them in the present study). Of the 1,008 subjects, 742 (73.6%) continued with

    complete participation in the entire study until its conclusion in March 1986. These 742 individuals constituted the

    reference sample for the present study. Inspection of the demographic characteristics of the 742 subjects revealed

    that individuals who participated in the study differed somewhat from the U.S. Census Bureau data for the Eugene

    Springfield area. Compared with the general population, participants were better educated and more likely to be

    women. Comparison of the initial 1,008 subjects with the 742 who completed the entire study revealed that older

    individuals were more likely to discontinue participation; no other assessed demographic differences were associated

    with attrition. Subjects received no financial reimbursement for participating in the study (except for occasional

    reimbursement of transportation costs) and signed a statement of informed consent, which assured confidentiality.

    Longitudinal DesignData were collected on psychopathology, depressive symptomatology, demographic characteristics, and the

    psychosocial variables of interest at multiple assessments. T1 occurred between May 1982 and November 1983 and was

    defined as the date on which the subject completed both the questionnaire and the diagnostic interview. Subjects

    were interviewed within approximately 2 weeks after returning the questionnaire, so that self-report data and

    interview-based data essentially were obtained concurrently. T2 occurred between November 1984 and March 1986

    and was defined as the date that the subject was readministered the self-report questionnaire and was reinterviewed.

    The average time that elapsed between T1 and T2 was 2.4 years. Additionally, to identify subjects who became

    depressed between T1 and T2, we implemented case-finding procedures, as described in the next section.

    Case Finding

    Our goal was to record all episodes of depression and other psychopathology that occurred between T1 and T2. Toidentify individuals who became depressed after T1, subjects were mailed the Center for Epidemiological Studies

    Depression Scale (CESD; Radloff, 1977) approximately every 2 months. The CESD is a self-report measure that

    assesses the frequency of occurrence of 20 depressive symptoms. Completion rates were high, averaging 80% (of the

    1,008 T1 subjects) across the nine mailings. Any subject who was not diagnosed as depressed at T1 and scored above

    11 on any CESD administrations in the post-T1 phase was considered for a post-T1 follow-up interview to determine

    whether they had become depressed. Twenty-five percent of the returned CESD questionnaires had scores above 11.

    Because of administrative and financial constraints, not all subjects with elevated CESD scores were interviewed

    during the post-T1 phase. Higher priority was given to subjects with higher CESD scores. Six hundred post-T1

    interviews were conducted with 386 subjects (38.3%) from the T1 sample (55.4% of the 386 subjects had multiple

    post-T1 interviews). The mean CESD score for the 386 subjects was 18.97 (SD= 5.99, range-1247). These procedures

    identified 105 Cases, who were judged to have experienced a diagnosable episode of depression that began after T1.

    During the T2 phase of the study, 749 of the T1 subjects (74.2%) again were interviewed and were administered

    the self-report measures that were assessed at T1. Resource constraints prevented follow-up of the entire T1 sample.

    Therefore, highest priority for T2 interviews was given to subjects (a) who had been depressed at T1, (b) who had

    become depressed at any time during the post-T1 period (i.e., Cases), (c) who had a past history of depression, or (d)

    who reported an elevated level of depressive symptoms on the final post-T1 CESD questionnaire. These criteria

    identified 391 subjects. A random sample of 358 (66.3%) of the 540 T1 subjects who had reported no evidence of past

    or current depression were also reinterviewed as control subjects. This resulted in a total of 749 subjects who were

    assessed at T2. It is important to note that the mean T1 and T2 CESD scores were not significantly different. Data for

    7 subjects were excluded from analyses because of missing data, evidence of organic disorder, or evidence of deviant

    or random responding to questionnaire items; thus, 742 subjects were left as the reference sample. In addition to the105 Cases identified in the post-T1 phase, T2 interview procedures identified 41 Cases. Seven Cases from the post-T1

    phase were lost before T2 follow-up (2 were deceased, 1 refused to participate, and 4 could not be located).

    Therefore, complete data for 139 individuals who became depressed after T1 were available for subsequent analyses.

    Note that only a few of the 139 Cases developed their first depressive episode during the course of this study; the

    majority of these subjects had a past history of depression. The important fact is that all of the Cases were not

    clinically depressed at T1.

    Diagnostic Classifications

    The diagnosis of depression and other psychopathological syndromes was based on information gathered from

    participants in 2-hr semistructured interviews, using the Schedule for Affective Disorders and SchizophreniaLifetime(SADSL; Endicott & Spitzer, 1978) for T1 and using the Schedule for Affective Disorders and SchizophreniaChange

    (SADSC; Spitzer & Endicott, 1977) for post-T1. At T2, the Longitudinal Interval Follow-Up Evaluation (LIFE; Shapiro &

    Keller, 1979) was conducted. The LIFE interview provided detailed information about the longitudinal course of

    psychiatric symptoms and disorders since the last (T1 or post-T1) interview, with rigorous criteria for recovery from a

    disorder. Decision rules specified by the Research Diagnostic Criteria (RDC; Spitzer, Endicott, & Robins, 1978) were

    used to combine information obtained through the interviews into specific RDC nosological categories.

    Diagnostic interviewers were a carefully selected group of graduate and advanced undergraduate students

    enrolled in a yearlong didactic and experiential diagnostic interviewing course. The training procedure was an

    extension and modification of the training model proposed by Gibbon, McDonald-Scott, and Endicott (1981), with

    additional training regarding the interviewing of elderly subjects. The SADSRDC procedure has been shown to be arelatively reliable and valid method of making retrospective diagnoses of psychiatric disorders for both psychiatric

    patients and nonpatient samples, with measures of reliability generally exceeding .80 (Mazure & Gershon, 1979;

    Spitzer et al., 1978). Interviewers were unaware of questionnaire data, subject selection procedure, and the specific

    hypotheses under investigation. Interrater reliability of diagnosis was evaluated by means of the kappa statistic ( J.

    Cohen, 1960). On the basis of joint ratings, the kappa coefficient was .81 for 193 T1 SADSL interviews, .81 for 101

    post-T1 SADSC interviews, and .82 for 147 T2 LIFE interviews. All kappas indicated an acceptable level of reliability

    for the diagnoses.

    Four subject groups were of interest in the present study. First, we were interested in the general sample of

    individuals who participated in the entire study. Three additional groups were also of interest on the basis of

    information gathered in the diagnostic interviews: individuals who were depressed at T1; individuals who becamedepressed after T1 (Cases); and control group individuals, who reported no past or current depressive episodes at

    both T1 and T2. Table 1 contains demographic information for the four groups of subjects.

    Assessment of Sociodemographic Variables

    Subjects reported their sex, age, marital status (married, divorced/ separated, widow/widower, or never

    married), educational level (eighth grade, high school, some college/vocational school, college degree, or

    professional degree), and employment status (employed, unemployed and seeking, or retired).

    Assessment of Coping Behaviors

    Several frequently used measures of coping were inspected by three psychologists (P. M. Lewinsohn, M.

    Hautzinger, and L. Teri). Items were selected from the various measures in an attempt to represent a wide variety of

    coping behaviors but at the same time to avoid redundancy and excessive length.

    Self-control behaviors

    Because of its extensive prior use and reported psychometric soundness, the entire Self-Control Scale

    (Rosenbaum, 1980) was selected. This instrument was developed as a measure of learned resourcefulness

    (Meichenbaum, 1977; Rosenbaum, 1980), which refers to the acquired repertoire of behavioral and cognitive skills

    used by people to regulate internal events, such as emotions and cognitions, that might otherwise interfere with the

    smooth execution of a target behavior (Rosenbaum, 1980). The measure consists of 36 items that describe (a) use of

    cognitions and self-statements to control emotional and physiological responses, (b) application of problem-solving

    strategies, (c) ability to delay immediate gratification, and (d) perceived self-efficacy. Each item consists of a

    statement used to describe people. Subjects were asked to describe yourself according to these characteristics, by

    checking the description which best applies to you using a 6-point scale. Testretest reliability from T1 and T2 of the

    Self-Control Scale was .76 (p

    7/21

    microstressors. This measure, called total stress, was developed so that the final numbers of analyses would not be

    overwhelming; it is described later in this article.

    Macrostress

    We measured macrostressors, or major life events, at T1 and T2 with a subset of 18 items from the Social

    Readjustment Rating Scale (Holmes & Rahe, 1967). The 18 items were selected on the basis of applicability to an older

    sample. In addition, items were deleted from the original scale if they represented a symptom of depression (e.g.,Change in eating or sleeping habits). Individuals rated whether they had experienced each of the 18 events during

    the past 6 months, and a total macrostress score was computed that was based on the average frequency of the 18

    events. The measure of item homogeneity was seen as inappropriate, given the nature of the items.

    Microstress

    We assessed microstressors, or ongoing hassles, at T1 and T2 with 44 items from the Unpleasant Events Schedule

    (Lewinsohn, Mermelstein, Alexander, & MacPhillamy, 1983). Items were selected on the basis of applicability to an

    older sample and previously reported association with depression (Lewinsohn et al., 1983). The items describe

    aversive experiences that are part of everyday life (e.g., Having arguments with spouse; Having to do things I do

    not like to do). Subjects rated these events on a 3-point scale in terms of frequency of occurrence during the past 30

    days. A total microstress score, which was based on the average frequency of all 44 events, was computed.Coefficient alpha at T1 was .85, and the T1T2 correlation was .68 (p

    .04, ns).

    Factor 3, which contained 10 items and accounted for 5.8% of the total item variance, was labeled Solace

    Seeking. All of the items in this factor were from the effective antidepressive behaviors. Items that loaded highest on

    Factor 3 included the following: Plan something pleasant (.69), Spend time with friends (.67), Do something

    enjoyable (.64), Spend time with a relative or a close friend (.60), and Do something to restore your pride (.59).

    Internal consistency at T1 and T2 was .80 and .83, respectively, and testretest reliability was .53 (p

    Unexpectedly, gender was not predictive of an increase in reported depression symptoms. Conversely, CESD atT1 was highly predictive of the final CESD score, as was the main effect of T1 total stress. Individuals who reported

    more symptoms of depression or stressful events and hassles at T1 were more likely to report an increase in depressive

    symptoms at the future assessment.

    Of the three coping factors, only Ineffective Escapism significantly predicted an increase in symptoms of

    depression. This coping factor had both a significant main effect and significant interaction with stress, although the

    use of Ineffective Escapism was not a buffer against stress. Instead, the use of these avoidant, passive, and reckless

    coping behaviors represented a vulnerability. Individuals who reported more use of behaviors within this factor were

    more likely to be negatively affected by stress.

    Corroborating results were obtained in regressions using the four original coping scales. The Self-Control Scalehad a significant main effect in predicting future CESD scores. Although items from the Self-Control Scale had loaded

    on both Factors 1 and 2, one may assume that only the apparently unhelpful items of this scale that were contained in

    Factor 2 (e.g., I cannot avoid thinking about mistakes I have made in the past and If I had the pills with me, I would

    take a tranquilizer whenever I felt tense and nervous) contributed to the scale's ability to predict future depression

    symptoms, because Factor 1 (which contained many apparently helpful Self-Control Scale behaviors) was unrelated to

    increased future CESD scores. Both ineffective antidepressive behaviors and passivity behaviors had additive and

    interactive effects in predicting an increase in future CESD scores. Again, instead of acting as a buffer, frequent use

    of these coping behaviors represented a vulnerability that exacerbated the negative impact of stress. Effective

    antidepressive behaviors at T1 were unrelated to increased depressive symptoms.

    Role of Coping in Predicting a Diagnosis of DepressionWe used similar hierarchical multiple regression procedures to predict the development of a depression diagnosis

    after T1. Gender, CESD scores, and total stress scores at T1 were entered first, followed by one of the coping

    measures and its interaction with total stress. Results appear in Table 3.

    As anticipated, gender, T1 CESD scores, and total stress scores each were highly predictive of the future

    diagnosis of depression. Such results replicate the generally accepted findings that women, individuals reportingsubclinical dysphoria, and those reporting high levels of stress are at elevated risk for a future diagnosis of depression.

    In addition to gender, T1 CESD scores, and total stress scores, both Ineffective Escapism and Solace Seeking

    significantly contributed to predicting the future diagnosis of depression. As it did in predicting future CESD scores,

    Ineffective Escapism represented a vulnerability, especially in the presence of increased levels of stress. Use of these

    coping behaviors increased the likelihood of a person's being diagnosed as depressed, especially when the individual

    had reported high levels of stress. On the other hand, Solace Seeking significantly mediated the impact of stress,

    decreasing the likelihood of a person's becoming depressed. Individuals who reported spending time with others and

    engaging in enjoyable activities were less likely to be diagnosed as depressed later, given high levels of stressful

    events in their lives.

    Regression procedures using the four original coping measures provided further insight into the role of coping.

    Although the Self-Control Scale did not mediate the impact of stress, it was independently predictive of future

    depressive episodes. We assumed that primarily the apparently bad coping behaviors of the Self-Control Scale were

    most predictive of future depressive episodes, rather than was the entire scale, because Factor 1 had no significant

    relation to the future diagnosis of depression. Review of the other two original scales that constituted Factor 2

    indicated that ineffective antidepressive behaviors had a significant main effect and that passivity behaviors had a

    significant interaction with stress. As seen before, reported use of these coping behaviors represented an increased

    vulnerability to stress, rather than a buffer. Use of effective antidepressive behaviors did not predict subsequent

    depression, which is noteworthy because the Solace Seeking factor (formed exclusively of items from effective

    antidepressive behaviors) had significantly mediated the impact of stress in relation to future depressive episodes.

    Because the three-factor solution accounted for only 25% of the total item variance, we computed a fourth,

    residual factor from the 17 items that had not been assigned to one of the other three factors. As expected, the

    coefficient alpha of the residual factor was somewhat low (.54), and it was significantly correlated with each of the

    other three factors, especially with Factor 2. Although the residual factor had a significant main effect for predicting

    future increases in CESD score, F(4, 759) = 4.68,p= .031, and future diagnosis, F(4, 626) = 8.84,p= .003, when it was

    entered in combination with Ineffective Escapism, the residual factor accounted for no additional variance.

    Further Analysis of Maladaptive Escapism in Predicting Depression

    Of the three coping factors in the present study, Ineffective Escapism (Factor 2) was most strongly associatedwith becoming depressed. For this reason, we used stepwise multiple regression procedures to examine the specific

    items within Factor 2 that were most predictive of future depression. Using the criteria of a significant (p

  • 7/28/2019 5- Dimensionality of Coping and Its Relation to Depression

    12/21

    Much debate has focused on the adequate measurement of stress. In the present study, we measured stress by

    frequency counts of major stressful life events and daily microstressors. Some researchers have argued that measures

    of stress should quantify the perceived impact or cognitive appraisal of threat, in addition to the simple fact of

    occurrence (Hammen, Marks, Mayol, & deMayo, 1985). Others have noted the possible confound between events and

    psychopathologynamely, that psychopathology may be a cause, as well as a consequence, of adverse life events

    (Depue & Monroe, 1986). For example, varying degrees of depression might bias an individual's report of stress,

    particularly the report of more ongoing hassles. One interpretation of the high internal consistency of microstress inthe present study is that the measure was confounded with psychopathology. Because stress could have been

    confounded with concurrent depression, the longitudinal design of the present study was especially important.

    Measuring coping and stress at T1, before the occurrence of future depression, greatly reduced this potential

    confound. In addition, the fact that total stress at T1 predicted both measures of future depression after we

    controlled for T1 depression level represented a strong argument for the construct validity of the stress measure. We

    were therefore quite confident in our measurement of stress.

    A final limitation to the generalizability of our findings involved the nonrandom selection of subjects because of

    voluntary participation. Although our situation was not ideal, the study sample was large, participation rates were

    high, and the demographic distribution was roughly similar to the general over-age-50 population. Attrition in the

    study was generally low and tended to be random, with the one noted exception that older individuals were morelikely to discontinue. Therefore, the sample was judged to be more than adequate for testing the hypotheses of

    interest, with the caveat that results may not be as readily generalizable to younger or less well educated samples.

    Although we have acknowledged several limitations, the present study had several important positive features.

    The large sample of community residents enhanced the generalizability of results, as compared with clinical or student

    samples. The prospective, longitudinal design allowed a truly predictive analysis of coping and future depression; data

    regarding coping and stress at T1 were uncontaminated by future depression. In addition, the readministration of T1

    measures at T2 allowed for cross-validation of the factor analyses. Finally, depression was not measured solely by a

    self-report symptom scaleas is often truebut was additionally assessed by rigorous diagnostic criteria. This provided

    a comparison of results with the two different outcome measures, thus increasing our confidence when results were

    the same for both measures of depression. The data set was seen as impressive for a number of reasons and as quiteadequate to address the present issues.

    Dimensionality of Coping

    The three factors identified by our analyses were psychometrically robust and meaningful. The factors were

    reasonably independent and had good internal consistency (item homogeneity). They showed considerable stability

    over time and were consistent under cross-validation at T2. The factors were also psychologically interpretable, falling

    into three broad domains: (a) problem solving and cognitive self-control, (b) passivity and avoidant behaviors, and (c)

    spending time with others and engaging in enjoyable activities. Although not ideal, the three-factor solution appeared

    optimal.

    All three coping factors were associated with gender (women used more Cognitive Self-Control and SolaceSeeking, but men used more Ineffective Escapism); none were related to age. In comparison, Parker and Brown

    (1982)reported that women used more self-consolation which is related to Solace Seeking in the present study. They

    also reported several age differences: Younger people reported more reckless behaviors and less use of distraction

    and passivity. The meaning of the various gender differences in the current study is unclear; results need to be

    replicated. One explanation for the lack of age effects in the present study is that only older subjects (50 or more

    years old) were involved, thus restricting the age range.

    Results of the present study were broadly consistent with the results of other factor-analytic studies of coping.

    Although specific factor solutions varied across studies, the dimensions of coping that have been identified thus far

    include various forms of cognitive self-control (e.g., reappraisal, self-distraction, cognitive problem solving, and

    positive self-talk); social support seeking (e.g., emotional support, social activity, and help seeking); instrumentalproblem-solving behavior; seeking compensatory relief; and relatively maladaptive responses (e.g., wishful thinking,

    self-blame, escapism, catastrophic thinking, and self-denigration). The coping factors variously reported by Folkman

    and Lazarus (1988), Parker and Brown (1979), Billings and Moos (1982), and Aldwin and Revenson (1987)generally

  • 7/28/2019 5- Dimensionality of Coping and Its Relation to Depression

    13/21

    consisted of subsets of these many dimensions. Of course, the different coping factors obtained depended on, among

    other things, the initial items included in analyses, the response formats, and the situations addressed by the subjects

    (e.g., a specific stressful event, general personality descriptions, and interpersonal stress events). Clearly, although a

    good deal of consensus exists regarding the dimensionality of coping, it would be premature to suggest that a

    definitive answer has been reached.

    We had assumed that the three selected instruments measured the same underlying construct. However, thisassumption was not supported by the results. Cognitive Self-Control (Factor 1) and Solace Seeking (Factor 3) were

    constructed exclusively from self-control behaviors and effective antidepressive behaviors, respectively. On the other

    hand, Ineffective Escapism (Factor 2) contained items from self-control behaviors, ineffective behaviors, and passivity

    behaviors. Thus, Factor 2 appeared to assess an underlying factor contained within all the instruments, namely, poor

    coping.

    Both the present findings and work by other researchers suggest that coping is a multidimensional construct that

    is not adequately represented by a single score. This is true even if one ignores variance that is due to varying item

    pools and differing targets of coping (e.g., stressful situations vs. stressful interpersonal encounters). One concern is

    that only 25% of the total item variance was accounted for by the three factors; 13 coping factors would have been

    required to account for 50% of the item variance. The total item pool was thus quite heterogeneous. In conclusion,our factor results appeared to be relatively consistent with other reported findings in suggesting that coping behaviors

    consist of a somewhat heterogeneous pool of behaviors.

    Coping and Concurrent Depression

    The three T1 coping factors were examined in relation to T1 depression, as assessed with two measures of

    depression: T1 CESD score and T1 diagnosis (0 = never mentally ill, 1 = depressed at T1). Ineffective Escapism was

    significantly associated with both measures of T1 depression; more use of the behaviors in this factor was associated

    with higher levels of depression. Neither Cognitive Self-Control nor Solace Seeking was significantly associated with

    either measure of T1 depression. The nonsignificant results for these two factors were somewhat unexpected,

    although not completely inconsistent with previous research.

    Several studies have reported similar findings that relate coping to concurrent depression. Coyne et al.

    (1981)reported that depressed individuals used more wishful thinking and avoidance (both related to Ineffective

    Escapism) in addition to more emotional support seeking (in relation to Solace Seeking). Folkman and Lazarus

    (1986)compared depressed adults (on the basis of five CESD scores) to nondepressed controls. The depressed

    subjects in their study tended to use more escapeavoidance, confrontive coping, responsibility acceptance,

    self-control, and social supportseeking behaviors. The depressed group did not differ from controls on coping

    behaviors labeled distancing, planful problem solving, andpositive reappraisal. It is interesting that most studies

    (including the present) found more coping behaviors that increased the likelihood of depression (as opposed to

    behaviors that decreased the likelihood of, or prevented, depression). Exceptions to this pattern include Billings and

    Moos (1984), who reported more emotional discharge and less problem solving for depressed individuals, and Parker

    and Brown (1982), who reported less socialization and distraction seeking for depressed individuals, along with morepassivity. As can be seen, the coping behaviors reported by other researchers to increase with concurrent depression

    tended to be similar or identical to behaviors contained within Ineffective Escapism in the present study.

    Coping and Future Depression

    We examined the relations of gender, stress, and coping to future depression, as measured both by an increase in

    reported depressive symptoms and by a diagnosis of depression. The independent effects of coping on future

    depression were assessed by first entering gender, T1 CESD, and total stress into a series of multiple regressions,

    followed by the direct effect of coping and the interaction of coping and total stress. The longitudinal design provided

    an examination of the causal directionality of coping and depression (i.e., whether coping had a direct or interactive

    impact on future depression, independent of prior depression level).

    Although not of primary concern in the present study, several interesting findings deserve mention. First, the

    present results add to the small but growing number of prospective studies in which stress predicts future depression

    (e.g., Kaplan, Roberts, Camacho, & Coyne, 1987; Lewinsohn, Hoberman, & Rosenbaum, 1988; O'Hara, Neunaber, &

    Ovid: Dimensionality of Coping and Its Relation to Depression. http://0-ovidsp.tx.ovid.com.columbus.uhu.es/spb/ovidweb.cgi

  • 7/28/2019 5- Dimensionality of Coping and Its Relation to Depression

    14/21

    Zekoski, 1984). Second, we wish to highlight the finding that mild depression (elevated CESD score without a

    diagnosable depressive disorder) at T1 clearly predicted the future increase in CESD score and the development of a

    diagnosed episode of depression. These findings provide additional support to the growing recognition of chronic

    subsyndromal dysthymia as a risk factor for depressive episodes (Anashensel, 1985; Depue & Monroe, 1986; Lewinsohn,

    Hoberman, & Rosenbaum, 1988).

    Finally, female gender predicted the future development of a diagnosis of depression but did not predict anincrease in depression symptoms, as measured by the CESD, a finding that replicates results reported from our earlier

    work (Lewinsohn, Hoberman, & Rosenbaum, 1988). This rather intriguing finding, if replicated by other investigators,

    deserves further study aimed at clarifying the precise nature of the vulnerability that predisposes women to

    diagnosable episodes of depression (Weissman & Klerman, 1977). The two measures of depression (CESD and

    diagnosis) were included to measure the same underlying construct (i.e., depression), providing a multimethod cross-

    validation of findings. That gender predicted only one of the depressive measures underscores the fact that formal

    interviewer-derived diagnoses using rigorous criteria and self-report symptom scales measure the use of similar but

    not identical constructs.

    Of the three coping factors, Ineffective Escapism (Factor 2) had the strongest association with future depression,

    both directly and interactively predicting future depression. Subjects who reported greater use of the passive,avoidant, or reckless behaviors within this factor were more likely to become depressed, as measured both by

    increased self-reported dysphoria and interview diagnosis. The interactive impact of this factor was significant but did

    not represent a buffer. Instead, given an elevated amount of stress, subjects who reported more use of Ineffective

    Escapism behaviors were more likely to become depressed. Thus, use of the behaviors in Factor 2 exacerbated one's

    vulnerability to stress, instead of acting as a stress buffer.

    In general, the items within Ineffective Escapism that were most associated with future depression reflected a

    feeling of helplessness, uncontrollable negative ruminations, and nervousness. All of these behaviors suggested that

    feeling inadequate about one's personal resources increased the likelihood of both being and becoming depressed.

    We had assumed that some subset of coping behaviors would represent a buffer against stress; however, supportfor this supposition was weak. Cognitive Self-Control (Factor 1) had no significant relation to either measure of future

    depression. On the other hand, Solace Seeking was unrelated to increases in CESD scores but did significantly buffer

    the impact of stress on developing a future diagnosis of depression. These findings were somewhat consistent with the

    results of other studies in which positive coping behaviors had both direct effects (Felton & Revenson, 1987; Felton,

    Revenson, & Hinrichsen, 1984; Mitchell & Hodson, 1983) and interactional or buffer effects (Martin & Lefcourt, 1983;

    Pearlin et al., 1981). One possible interpretation for the weak or nonsignificant effects of positive coping in the

    present study is that engagement in behaviors that are generally negatively valued (e.g., behaviors in the Ineffective

    Escapism factor) constitutes a vulnerability but engagement in positive-valued behaviors (e.g., Cognitive Self-Control

    and Solace Seeking) does not confer an immunity. In other words, the presence of maladaptive coping behaviors in

    the person's repertoire is much more relevant to predicting depression than the presence of those behaviors that have

    traditionally been used to define coping.

    Of the original coping scales, most of our attention is directed to the Self-Control Scale, which was used in its

    entirety. Although this measure did not mediate the impact of stress, the Self-Control Scale had a direct effect in

    predicting both future increases in depressive symptoms and the diagnosis of depression. It was assumed that the

    apparently unhelpful items within this scale were most strongly predictive of future depression because the positive

    items (which generally loaded on the Cognitive Self-Control factor) were predictive neither of increased CESD scores

    nor of depressive diagnoses.

    The findings in this study suggest that currently depressed individuals use more negative or maladaptive coping

    behaviors and that these same coping behaviors are predictive of future depression. Findings such as these support

    Felton and Revenson's (1984)suggestion that a mutually reinforing causal cycle exists between poor mental health andmaladaptive coping; poor mental health predicts maladaptive coping as maladaptive coping predicts poor mental

    health. Perhaps such ineffective coping behaviors are partially responsible for the increased likelihood of formerly

    depressed individuals, compared with neverdepressed controls, to become depressed in the future (Amenson &

    Ovid: Dimensionality of Coping and Its Relation to Depression. http://0-ovidsp.tx.ovid.com.columbus.uhu.es/spb/ovidweb.cgi

    15/21

    Lewinsohn, 1981; Keller, Shapiro, Lavori, & Wolfe, 1982).

    Coping research has been used in attempts to understand which behaviors decrease the negative impact of stress,

    but what has more frequently been found are behaviors that exacerbate the effects of stress. Results of the present

    study only provide marginal support for the buffer hypothesis that good coping protects one against the

    depressogenic effects of stress. In only one of four analyses did positive coping behaviors (Solace Seeking) mediate

    the effects of stress on future depression. Much stronger evidence suggested that higher levels of IneffectiveEscapism (Factor 2) amplified the relation between higher stress levels and future depression (as measured by both

    self-reported dysphoria and diagnosed depression). In contrast to a buffer effect, Ineffective Escapism thus seems to

    create an increased vulnerability to the effects of stress. Perhaps poor coping behaviors are more easily measured, in

    comparison with the assessment of effective coping. A second possibility is that no consistently effective coping

    behaviors truly exist. Pearlin and Schooler (1978)suggested that a varied coping repertoire was much more important

    than any one particular coping strategy.

    Another possible explanation for the negative findings in regard to Cognitive Self-Control and the weak findings

    for Solace Seeking may be that a more precise match is required between the positive coping behaviors executed by

    an individual and the specific types of coping demanded by the specific stressful situation (Pearlin & Schooler, 1978).

    In the present study, as in other similar studies, coping behaviors were measured as if they represented a general skillthat facilitates the person's ability to deal with any stressful situation. It is possible that a more specific detailing of

    the type of situation (or stressor) with which the person has to cope is required, to illuminate the relation between

    the positive aspects of coping and stress. For instance, research on how patients cope with chronic pain (Copp, 1974;

    Tan, 1982; Turk & Genest, 1979) has shown that a number of successful cognitive and behavioral strategies, such as

    attempting to ignore or to reinterpret pain sensations or involving one-self in a distracting activity, are present.

    Therefore, many of the coping behaviors measured in the present study would be unrelated to effectively dealing

    with this specific type of stressor. It seems reasonable to assume the same of other stressful events. If this assumption

    were correct, future research might be directed at people who have recently, or who will soon, experience a specific

    stressor (e.g., loss of a job, birth of a baby, or recovery from a heart attack). Attempts could then be made to sample

    and measure the specific types of coping behaviors that people engage in, with the goal of identifying those behaviors

    that serve to increase or to decrease the likelihood of the person's developing a disorder in the situation. As is oftenthe case in science, questions that initially appear to be reasonably straightforward become increasingly more

    complex as they are examined.
