Over the past 20 years, the Multifactor LeaderTheory MLT) has become one of the mostdominant theories of leadership. This popularis due, in part, to the broad range of leadershibehav iors included in the theory. Bass 1985) colleagues conceptualized leadership as consising of three primary factors i.e., transform atiotransacfional, and passive/laissez-faire leadersand p rior research has clearly linked transformtional and transactional leadership to importanoutcomes, such as employee commitment andorganizational performance. Furtherm ore, priresearch has established that these behaviors cbe developed throug h training. However, it isless well understood how the importance of thbehaviors changes across organizational settinThe purpo se of this study, therefore, is to exam across two data sets) the relative importance othese leadership factors across various outcom i.e., team potency/efficacy, team cohesion, andperformance) and organizational contexts i.e.,
military and healthcare). Results indicate thattransformafional leadership behaviors arecritically important for team cohesion and teampotency/efficacy Data Set 1) and leadereffectiveness Data Set 2), and that transac tionaleadership becomes particularly salient withregard to actual task performance and extra ef Data Set and 2). Implications of these result
for practitioners are discussed, and a useful taxonomy to guide leadership development is provided.

Across settings, transformational leadershbehaviors have become o ne of the most doapproaches to understanding leadership efness (Lowe Gardner, 2001) and certain tmational leadership beha viors are includeleadership development programs from conies operating in industries ranging from oretail (e.g., Zappos .com ) to finance (e.g., Gtal; Hsieh, 2010). Furthermore, there is subtial evidence that transformational leadersbehaviors lead to important individual-levcomes such as employee commitment, motand task performance and organization-levcomes such as firm performance (Barling, Kelloway 1996; Bono Judge, 2004; BycHackett, Allen, 1995). Finally as describthe Multifactor Leadership Theory (MLT), dence suggests that transformational leadbehaviors augment, or build upon, transacleadership behaviors such as utilizing conrew ards (Judge Piccolo, 2004).
Thus, the extant research provide s reasonastrong sup port for the theoretical predicat

rived from the MLT (cf.. House Sham ir, 1993;well Avolio, 1993; Judge Piccolo, 2004;we et al., 1996). Nam ely, transac tional leader-p behaviors and transformational leadershiphaviors are necessary to effectively perform as ader and that transformational leadership addsremental value to more tradition al transaction-eadership behav iors. While prior research has
gely supported the theoretical tene ts outlinedthe MLT, leadership scholars have b egun to rec-nize that aspects of the situation, or organiza-nal context, impact w^hat leader beh avio rs areimately effective (Lord, Brown, Harvey, Hall,01; Shamir How ell, 1999). That is, the trans -rmational or transactional leader behaviors thate effective in one situation (e.g., the Peacerps) may not trans late to effective performancea different context (e.g.. New York Yankees
ont Office). The sam e is true across differentrformance criteria (Judge Piccolo, 2004). Inct, evidence (cf. Antonokis et al., 2003; Denrtog et al., 1999) clearly ind icates tha t the
ader behaviors that relate to some criteria (e.g.,

anizationally v alued criteria (e.g., team poten-
cy/efficacy, job performance, team cohesion) aorganizational contexts (e.g., private healthcarand military). This is particularly importan tbecause prior research has relied on faulty meures to assess predictor importance, and there some data suggesting that leadership behaviochange in importance across contexts (Den Haet al., 1999; Johnson LeBreton, 2004; LeBretoHargis, Griepenti-og, Oswald, Ployhart, 2007)Additionally, these data will help practitionerscreate leadership development approaches thaare more cost and time-effective, and context ssitive, due to the increased aw areness of whichbehaviors are most related to desired outcomeacross different organizational settings.
In the text that follows, we: 1) outline the leadship behaviors included in the multifactor leadship theory, 2) present the results of a studydesigned to examine how the relative importaof these leadership behaviors change across diferent organ izational settings (military and meical) and across outcomes such as team
potency/efficacy, team cohesion, and job perfoance, and 3) presen t a leadership developm enttaxonomy (based on the results of the currentstudy and a review of best practices) designedaide practitioners in the development and chanprocess.
Multifactor Leadership Theory
The multifactor leadership theory developed bBass (1985) has received a great deal of theoretand empirical attention over the past nearly thdecades (Bass Avolio, 2000; Judge Piccolo,2004; Lowe, Kroeck, Sivasub ramaniam, 1996This popularity is due, in part, to three primarfactors. First, the model of leadership introdu
by Bass encompasses a broad range of leader

behaviors including transformational, transaction-al, and non -leadersh ip (or laissez-faire). Second,the scientific literature has generated substantialsupport for the major tenets of the theory (cf..House Shamir, 1993, How ell Avolio, 1993;Kirkbride, 2006; Lowe et al., 1996). Third, this
approach to leadership clearly focuses on behav-iors that can be developed through training andlearning (Parry Sinha, 2005) and these behav -iors have been linked to impo rtant ind ividual,group, and organization level outcomes (HaterBass, 1988; Howell Avolio, 1993; Lowe et al.,1996; Waldman, Bass, Yammarino, 1990). Forexample, Lowe et al. (1996) presen ted meta-ana-lytic evidence demonstrating that transformafion-al leadership was related to subjective and objec-five rafings of leadership effectiveness with cor-rected correlations of .73 and .30, respecfively.Additionally, prior research has demonstratedthat transformational leadership impacts creativi-ty and innovation (Avolio et al., 1999) and com-mitment (Bass Riggio, 2006). Finally, Dvir,Eden, Avolio, and Shamir (2002) presented evi-
dence suggesting that transformational leadershipresulted in better unit performance relafive togroup s that did not receive transformational lead-ership train ing. In the following text, each of thefactors included in the MLT will be discussed.
Transformational leadership. Transformationalleaders are described as being capable of m otivat-ing followers to transcend their self-interests toaccomplish collective goals (Bass, 1985).Transformational leadership includes four distinctfactors: ide lized influence inspir tion l motivationintellectu l stimulation nd individu lized considera-tion (Bass Avolio, 2000). The ide lized influencefactor represents transformational behaviorsdirected at influencing followers' perceptions of
fhe leader as powerful, confident, and capable of
accomplishing stated goals, as well as leadbehaviors that are directed towards goal atment and developing a sense of mission amfollowers. Key behavio rs include demonsthigh levels of competence and the effecfivepower to enhance group performance (Kirk2006). The inspirational motivation factor foc
on behaviors directed towards energizing motivafing followers, such as communicafivision and mak ing emotional app eals that followers strive towards future goals.Inspirational behav iors include presentingmistic (yet attainable) visions for the futurecreafing a unified sense of mission and pu(Kirkbride, 2006). The intellectu l stimul tiontor focuses on encouraging followers to criexamine their assumpfions, values, and beleffect, the intellectual sfimulafion factor is as the degree to which leaders favor new wdoing things and encourage followers to dthe skills necessary to think through and sproblems for themselves. Finally, the individua
ized consider tion factor focuses on leaderbehaviors that are aimed at understandingneeds of individual followers and encourathem to develop to their full potential in thsuit of challenging goals (Avolio, Bass, Ju1999; Bass Avolio, 2000).
Transactional leadership. The notion of trational leadership grew^ out of the exchangetheories of leadership that dominated the lship literature until the 198O's. Bass (1985)defined fransactional leaders as leaders whtify the needs of their followers and engagexchange relationships with them based ontives to be m et. The high er ord er factor ofactional leadership includes: contingent rewaactive mana gement by exception and passive m
ment by exception. Contingent rew ard lead ers

aracterized by the exchange of rewards fromders to followers for accomplishing objectivesss Avolio, 1993). With this style of leader-p, the leader sets clear goals and objectives andarly specifies what rewards (financial or non-ancial) can be expected for achiev ing goals.h ctive an d passive management by exception are
aracterized by the use of discipline to correctdesired behavior from followers. The differ-ce between the two approaches becomes appar-when one considers the m onitoring patte rn ofleader. Active managem ent by exception is
aracterized by the leader s continued observa-n of followers to en sure that agreed upon stan-rds of performance are met (Antonakis et al.,03). In contiast, passive ma nagem ent by excep-n leaders only intervene w^hen mistakes haveeady occurred (Antonak is et al., 2003).
n Leadership. The last leadership factorluded in the MLT is actually a non-leadershiptor, which is labeled laissez-faire lead ersh ip.is style of leadership is characterized by thesence of transformational or transactional lead-hip and a lack of interaction betw^een leader
d follower. In essence, this type of leade rsh ipuld be characterized by leaders who avoidking decisions and w ho fail to take interest
d responsibility in the growth of their unit,partment, or organization (Kirkbride, 2006).
summary, there are eight factors represented incurrent form of the m ultifactor leade rship the-. Bass (1985; Bass Avolio, 1993) suggests thath transformational and transactional leader
haviors are necessary to effectively perform as ader. Furthermore, Bass (1985) argued thatnsformational leadership behaviors augmenttransactional leader behaviors in predicting
anizational outcomes. Several studies support
this proposition. For instance, there is evidencthat transactional leadership behaviors lead toeffective leadership (Hater Bass, 1988; Waldmet al., 1990). Prior research also dem onstia tes after controlling for the effects of transactionalleadership, transformational leadership behaviaccount for incremental variance in ratings ofleader effectiveness (Hater Bass, 1988) and saisfaction with the leader Podsakof, MacKenzie,Moorman, Fetter, 1990). Additionally, theresults of a meta-analytic investigation of theMLT, conducted by Lowe et al. (1996), suggestethat the same leader might exhibit behaviors aciated with transactional and transformationalleadership, which is consistent with the theorypostulated by Bass (1985). This meta-analysis demonstrates that both types of leadership areassociated with leader effectiveness.
JVIethod
To examine how leader behaviors change inimportance across different criteria and organitional contexts, we reanalyzed the correlationmatrices from two published studies using tworelative importance indices that are increasinglbeing used in the organizational science literatDom inance Analysis and Relative WeightsAnalysis - both of which are intioduced in modetail in the da ta analysis section below. The uof these relative importance statistics is becom
more common in the organizational sciences (cBaltes, Parker, Young, Huff, Altinann, 2004;LeBreton, Ployhart, Ladd, 2001). These datasets were chosen because: (1) these two dataseallow u s to examine the relative importance offactors and sub-factors included in the MLTacross diverse samples (military vs. registerednurses) and performance criteria, and (2) the v
ables, as a group, explained a significant and

practical amount of variance in meaningfuldepend ent variables. These selection criteria areconsistent with the selecfion criteria utilized inother recent studies examining the relative impor-ance of variables in the organizational sciences
(cf.. Baltes et al., 2004; LeBreton et al., 2007).
Data Set : The first data set came from a studyconducted by Bass, Avolio, Jung, and Berson(2003) who examined the impact of transforma-tional and transacfional leader behaviors on twoteam outcom es: team potency/efficacy (represen t-ing the general belief that the team can successful-ly perform its mission) and team cohesion (repre-senting whether team mem bers pulled together toaccomplish tasks). The authors addressed theirquesfion using a sample of 78 platoon leaders andtheir direct reports.
t Set 2 : The second data set came from astudy conducted by Bycio, Hackett, and Allen(1995). These authors utilized a sample of nurses(N 1,376 to examine the impact of transforma-ional and transacfional leadership behaviors oneader effectiveness and extra effort from employ-
ees.
Data Analysis Relative Importance Indices
ohnson (2000, p. 2) defines relative importance asthe contribufion each variable makes to the pre-
diction of a dependent variable considering bothts unique contribution and its contribution whenombined with other variab les. Traditionally, aumber of stafisfics (e.g., squared correlafions andeta weights) have been used to evaluate predic-or impo rtance. While each of these meth ods ha strengths, they fail to consider the joint effects onhe criterion shared by two or more correlated
redictors (Johnson & LeBreton, 2004).
Darlington (1968) notes that most measurespredictor importance are often misleading variables are co rrelated, wh ich is often the the organizational sciences (LeBreton et al., This is very useful when considering the Mbecause transactional leadership and transftional leadership behaviors are often highlylated. For instance, Bycio, Hackett, and Al(1995) presented evidence demonstrafing thcontingent reward behaviors usually correlstrongly with transformational b ehaviors wintercorrelations rang ing from .63 to .70.Furthe rmore, Lowe et al. (1996) repo rted unrected correlations between the transformatfactors th at ran ged in ma gn itud e from .68 t
To overcome these lim itations, two stafisticapproaches have been introduced: dominananalysis (Budescu, 1993) and relative weighanalysis (Johnson, 2000). These stafisfics hrecently been used in the organizafional sciliterature in areas ranging from employee sfion (Van Iddeking e & Ployhart, 2008) to unstanding percepfions of fairness (Schleicher 2006). For exam ple, LeBreton et al. (2007) aVan Iddekinge and Ployhart (2008) bo th utirelative imp ortance indices to examine whiemployee selecfion tests best predicted job formance. Addifionally, Schleicher et al. (20utilized relative importance indices to examhow selection procedures that provided theopportunity to perform job related tasks poly influenced subsequent applicant reactionthe organizafion. Finally, Behson (2005) demstrated, via dominance analysis, that certainageme nt practices (e.g., supervisory suppo rautonomy, etc.) predicted a number of impooutcom es such as job safisfaction, wo rk streand intenfions to quit.

minance Analysis Dom inance analysis wasigned to furnish estimates of predictor impor-ce in the presence of co rrelated predic tors.minance analysis provides a measure of theative importance of m ultiple p redicto rs bymputing the mean squared semi-partial correla-n across all possible subset regressionsudescu, 1993). That is, for each variable, theminance weigh t represents the average useful-s of a predictor across all subset regressiondels. These dominance weights are then usedrank-order the predictors in terms of their rela-e importance. Statistically, for each var iable (j),
general dominance weight is calculated (Cj)d this weight represen ts the average useful-s of a variable across all subset regressions
zen Budescu, 2003). Thus, dominance analy-furnishes an index of relative importanceed on a variable's direct effect (i.e., when con-
ered by itself), total effect (i.e., conditional onother predictors ), and partial effect (i.e., condi-nal on all subsets of predic tors ) (Budescu,93, p. 544). Furthermore, general dominancealysis examines patte rns of a predictor's dom i-nce, which can be used to determine the specifpattern of a variable's relative impo rtanceoss regression models. Full dom inance occurs
en a variable is consistently m ore imp ortan tn any other va riable across all subset regres-ns.
ative Weights Analysis The second method.lative Weights Analys is (Johnson, 2000), pro-es a measu re of the relative im portance ofltiple predictors by using a principal com po-
nts approach to create a new set of uncorrelated
predictors that are maximally correlated with original set of predictors yet are orthogonal(uncorrelated) to one another. The criterion vaables are then regressed on the transformed prdictors yielding s tanda rdized regression coefficients. These coefficients are then squared andcombined with the squared standardized regresion coefficients to calculate importance estima
Both methods provide estimates of predictorimportance based on the proportion of the moR- that can be attributed to each indepe ndent dictor. Furthermore, all of these independentcomponents add up to the model R^. Becausethese methods provide estimates of importancthat sum to the model R^, it is possible to evalpredictors using the metric of their proportioncontribution to the model R^. Additionally, it ipossible to calculate rescaled relative importanestimates for both dominance and relativeweights by dividing each raw estimate by themodel R^. These rescaled importance estimates in

contributed by each independent predictor, whis a helpful method to communicate results.
Results
Bass et al. (2003) examined the predictive validof transformational and transactional leadershbehav iors of platoon leaders for ratings of unit
potency (i.e., group efficacy), unit cohesion, antask performance by examining data collectedfrom 72 platoon leaders. When consideringunit/team potency (see Table 1), which represethe belief that the team can carry out the missisuccessfully, our data indicate that transformational leadership behaviors are most importan(ranked #1) and account for approximately 42%

hip behaviors an d man agem ent by exceptionccount for 28 and 30 of the variance, respec-vely. With regard to team potency, transforma-onal leadersh ip fully dom inates transactionaleadership behaviors and management by excep-on. However, if we were just looking at the
andardized regression weights as our indicatorf importance (which is a comm on practice in therganizational sciences and deve lopm ent litera-
ure), we would likely make the attribution that aelationship w ith a .04 mag nitude is practicallynsignificant. However, when considered with
more appropriate importance indices, this vari-ble actually accounts for a significant nd mean-
ngful amount of variance.
When considering team cohesion (see Table 2),ansformafional leadership fully dominates
management by excepfion/passive leadershipehaviors. More specifically, transformationaladership accounts for 39 of predicted vari-
nce followed by 33 for transactional and 28
for managemenf by excepfion. Finally, in fermof performance during a full-scale training excise (see Table 3), transform ational leadersh ipbehaviors became relatively less important.More specifically, transactional behaviors accfor 36 of predicted variance and passive lea
ship/management by exception accounted for33 of predicted variance. Both variables fulldominated transformafional leadership, whicaccounts for 31 of predicted variance.However, by examining the re-scaled importaestimates (which reflect percentages) we see teach variable accounts for roughly equal portof predicted variance.
The Bycio et al. (1995) stud y allows us to lookthe relative effectiveness of the sub-factors of MLT across different criteria (i.e., leader effec-tiveness and extra effort fiom employees). Aspresented in Table 4, idealized influence (orcharisma) was the most important predictor wregard to leader effectiveness accounting for 41

Discussion
Taken as a whole, the results from the currstudy clearly indicate that transformationalership behaviors are critically im portan t wconsidering team cohesion and team potenccacy (Data Set 1) and leader effectiveness (Set 2). While transformational leadership is

Leadership Development Best Practices
Partly due to the recognition of the value thateffective leadership has on organizational per-formance and partly due to a shrinking talentpool as a result of baby-boom generation retire-
ments and falling birthrates, organizations aredirecting greater resources into leadership devel-opm ent (Avolio, Avey & Quisenberry, 2010;Fulmer, 1997; Riggio, 2008). Indeed, in the 2009BusinessWeek.com and Hay Group's BestCompanies for Leadership Survey, the 20 mostsuccessful companies placed a premium on select-ng, developing, and retaining effective leaders at
every organizational level. As a consequence,eadership developmen t is viewed as a growth
area for organizational consultants.
While there are clearly many different means todeveloping leadersh ip, effective leadersh ip devel-opment has more to do with the quality of theoverall design, integration, and consistent imple-mentation than w ith the actual choice of the rele-vant components (Day, 2001; Day Halpin, 2001;McCauley, Velsor, Ruderman, 2010). Onerecent approach that reflects the increasingly criti-cal and strategic imperative for op timal organiza-tional effectiveness is the emergence of best prac-tices with regard to leader and leadership devel-opm ent. Yet, a review of the literature shows thatthere is little consensus in the field on what con-
stitutes best practices and how such aspirationalbenchmarks are applied in business organizations(Haskins & Shaffer, 2009). Nonetheless, a numberof key components of effective leadership devel-opment are noted below:
Aligning leadership compe tencies withbusiness strategy
Fostering innovation, creativity, andcontinuous improvement
Recruiting, identifying and deve lopifuture talent and succession
Executing and prom oting organizatistrategy and change
Building customer and em ployee loy
Engaging in a suppo rtive organizati
culture Eva luating the efficacy of leadersh ip
development initiatives and program
Although this study represents a useful extof previous research, there are research quethat remain unad dress ed. For example, therent study, as well as the previous investigaexamining the impact of context on the leaprocess, has only considered one variable atime. Given that hu m an behavior is determby multiple elements, a useful area for futuresearch would be to examine the impact otiple contextual variables concurrently.Additionally, most of the research examinintransformational leadership process has focon the positive outcomes associated with trmational leader behaviors. While this workincredibly useful, it does not consider the cof this behav ior. Thus, another area of futuresearch could explore the various intraindcauses (e.g., personality, m otivation, valuestransforming behaviors.
