Abstract
Purpose The aim of this study was to translate the
Attribution Questionnaire-27 (AQ-27) to the Italian lan-
guage (AQ-27-I), and to examine the reliability and
validity of this new Italian version.
Methods The questionnaire was translated using the
standard translation/back-translation method. Cronbach’s
alpha and intraclass coefficients were used to estimate
instrument reliability. Confirmatory factor analysis was
conducted to corroborate the original English version
factor structure in the new measure, and to establish
validity. Path analyses were meant to validate relationships
found in the English version among Italian-speaking
participants.
Results The AQ-27-I demonstrated acceptable internal
consistency, with a Cronbach’s alpha of 0.82 for the total
scale and ranging between 0.52 and 0.91 for the subscales.
The test–retest reliability was also satisfactory, with
intraclass correlation coefficients of 0.72 for the total scale
and ranging between 0.51 and 0.89 for the subscales. Fit
indices of the model supported the factor structure and
paths.
Conclusions The AQ-27-I is a reliable measure to assess
stigmatizing attitudes in Italian.

Introduction
People suffering from mental illness are more severely
stigmatized than those with other medical conditions, often
resulting in negative social, political, economic and psy-
chological outcomes [1–3]. Members of the general public
are less likely to interact with persons with mental illness
[4]. Stigmatizing attitudes contribute to discriminating
practices in everyday life situations, restricting private and
public institution opportunities. For fear of stigmatization,
individuals with mental illness may disengage from soci-
ety, resulting in worsening of their clinical conditions and
prognosis [5–7].
Stigmatization can be conceptualized as a process that
entails complex cognitive–behavioral interactions between
the individual and the social environment [8]. There are

two leading theoretical explanatory models of stigmatiza-
tion: Corrigan et al. [9] conceptualize public stigma as the
status loss and discrimination triggered by negative preju-
dices toward people with mental illness by those around
them. Link and Phelan [10] focus on self-stigma and con-
ceptualize it as the reactions of individuals who belong to a
stigmatized group when facing the stigmatizing attitudes
they apply against themselves. Stereotypes, prejudice and
discrimination are the cognitive, emotional and behavioral
components of the two models: stereotypes are negative
beliefs, addressed to other for public stigma (e.g. danger-
ousness or incompetence), or to self for self-stigma (belief
of being incompetent); stereotypes activate the emergence
of prejudice as their cognitive and emotional response (fear
or anger for public stigma, low self-esteem for self-stigma),
subsequently leading to the behavioral reaction of dis-
crimination (e.g. avoidance or withholding employment
and housing opportunities for public stigma; fails to pursue
work for self-stigma) [11]. Two further concepts are
described in the context of the public stigma model, those
of responsibility and dangerousness. The first is based on
Weiner’s attribution theory [12]: if the patient is deemed
responsible for his/her disorder, then people may be angry
with him/her, and will not provide assistance; if instead the
patient is considered a victim of the disorder, then he/she
will evoke feelings of pity and readiness to help. According
to the theory of dangerousness [13, 14], those who perceive
psychiatric patients as dangerous will fear and subse-
quently avoid them. Examples of stigmatization typically
include less job opportunities and social exclusion or bul-
lying. Stigma often emerges in the context of mental ill-
nesses, particularly schizophrenia [15], due to its disruptive
effects on behaviour and functioning, the side effects of
antipsychotic medications used to treat it, and uncertainties
as to its etiology and trajectory [16, 17].
The need to overcome stigma stimulated the creation of
a number of public health programmes in different coun-
tries, such as the Changing Mind Campaign by The Royal
College of Psychiatrists in the UK [18], the Psyke Cam-
paign in Sweden [19], the National Mental Health Charity
SANE in Australia [20], and the World Psychiatric Asso-
ciation’s Global Programme Against Stigma and Discrim-
ination because of Schizophrenia [21, 22]. Moreover,
elimination of stigma associated with mental illness was
identified as one of the central goals in public health by the
World Health Organization, at the European Ministerial
Conference on Mental Health in Helsinki in 2005 [23, 24].
Importantly, previous studies have shown that beliefs,
expectations, and attitudes about behavioural disturbances
predict stigma more than a strictly biomedical conceptu-
alization of schizophrenia [25], and that effective anti-stigma
campaigns should focus on these elements, following a
multidimensional, target-tailored approach [26].
Over the last few decades, Italy has made substantial
strides in improving public awareness and understanding of
mental illness. A number of examples include a 1978 de-
institutionalization directive outlined in law 180 leading to
gradual replacement of mental hospitals with community-
based psychiatric health care organizations, exclusion of
‘‘dangerousness to self and to other’’ as criteria for com-
pulsory mental health hospital admission, and creation of
advocacy groups such as the Italian Association Against
Stigma in 2003 [27]. However, much work in de-stigma-
tizing mental illness in Italy remains to be done. Increase of
interest on this subject in the general public and the media
has been recently witnessed by the release of movies and
TV-series dedicated to mental disorders, the history of the
Italian psychiatric reform and the work initiated by Franco
Basaglia, though the contribution to de-stigmatization of
these initiatives is controversial. Magliano et al. [28]
examined beliefs on causes, treatments, and consequences
of mental illness among 1,888 subjects including lay peo-
ple, mental health professionals, and relatives of patients
with schizophrenia across Italy, by means of a self-reported
questionnaire; the findings suggested a need to improve
information made available to the general public on what
schizophrenia is, how it is treated, and its causative role in
dangerous behaviours [28, 29].
At present, there are two instruments measuring stigma-
tization in the Italian language: ‘‘The Community Attitudes
to The Mentally Ill III’’ [30] is a questionnaire consisting of
40 statements concerning the acceptability of mental health
services and patients with mental disorders in the commu-
nity. Factor analysis of this measure detected three relatively
independent factors: physical distance and fear, social dis-
tance and isolation, and social responsibility and tolerance
(but Cronbach’s alpha values are unknown). The Ques-
tionnaire on the Opinions about Mental Illness (QO) [31] is a
self-reported instrument that assesses beliefs about: the
causes of schizophrenia, the effectiveness of available
treatments for this disorder, the political, social and affective
rights of the patients with schizophrenia, and their ability to
perform social and occupational roles; QO test–retest reli-
ability ranged from 0.50 to 1 for 74% of the items (Cohen’s
kappa coefficient), while Cronbach’s alpha coefficient ran-
ged between 0.56 and 0.66 (family version) and between
0.42 and 0.72 (professional version).Unfortunately, these
two existing questionnaires are not appropriate measures for
elements of the stigmatization process; moreover, the QO
was not designed to be used in the general population, but
only among relatives of psychiatric patients.
Therefore, despite these efforts, evidence and data on
stigma, its psycho-social correlates and outcomes of
stigma-reducing public campaigns in Italy are still few and
sparse and appropriate measures for the assessment of
stigma and stigmatization processes need to be developed.

The current study focuses on measurement of public
stigma. Several measures have been developed to evaluate
public attitudes toward mental illness [16, 32–35]. Among
them, the Attribution Questionnaire-27 (AQ-27) [36] con-
stitutes a feasible and effective self-administered measure,
designed to explain attitudes, affect, and behavioural
intentions related to a hypothetical person suffering from
mental illness. AQ-27 is based on the two explanatory
stigma models previously described: the attribution theory
[37] and Link’s theory concerning dangerousness [38]. The
two pathway models have shown to relate to each other
[39], leading to an integrated definition of stigma.
Acknowledging the lack of a reliable instrument mea-
suring stigma in Italian language, and existing evidence for
reliability of the original English version of AQ-27, the aim
of the current study was to examine the reliability and
validity of the AQ-27 translated into Italian language (AQ-
27-I). Factor structure will be confirmed on the Italian
sample, as will conceptual paths.
Methods
Instrument description
The AQ-27 was tailored as a 27-brief statement questionnaire
about an imaginary patient called ‘‘Harry’’, a 30-year-old
single man with schizophrenia. Individuals who complete
the measure are asked to rate how much they agree with
each statement made about ‘‘Harry’’ on a Likert scale from
1 (not at all) to 9 (very much). Two previous confirmatory
factor analyses were used to develop a measurement model
that demonstrates an acceptable fit to the data and provide
psychometric efficacy to the questionnaire [36, 40].
Measure translation
The translation of the original version of AQ-27 was a
three-step process. In the first step, three native Italian
speakers, bilingual in English, independently translated the
original instrument into Italian. A collaborative pooled
version of the questionnaire was then obtained from the
three translations. In the second step, the pooled version was
back-translated into English by a professional translator. A
draft Italian version of the instrument for student testing
was obtained from the comparison between the original
questionnaire and the back-translation. The third and final
step consisted of testing the draft Italian version on 30
Italian-speaking students (as many males and females) from
the University of Modena and Reggio Emilia, at group
meetings conducted by the authors; at the meetings, every
item was read out aloud (with participants also following
the text on paper-printed copies) and a group discussion
followed, with students required to answer two questions
for each items: ‘‘What does this statement mean to you?’’
and ‘‘Is there any other wording that enables this meaning to
be expressed more clearly?’’. The face validity of the
questionnaire was not tested by quantitative methods, but
through the group discussion just described. Answers were
subsequently analysed by the authors (LP, SF and MF),
leading to the final Italian version of the AQ-27 (AQ-27-I),
whose psychometric properties were then tested.
Sample
An opportunistic sample of relatives of students from
Modena and Reggio Emilia University was collected.
Students were asked to contact and have the questionnaire
filled in by five of their relatives at their choice. Inclusion
criteria were: (1) being aged over 18; (2) not having a first-
and second-degree relative suffering from a well-defined
mental illness. Of the 225 subjects contacted, only 11
(4.89%) did not respond or completed the questionnaire,
providing a final sample of 214 subjects.
Statistical analysis
The Statistical Package Social Sciences (SPSS) version
13.0 and Amos version 18.0 were used for data analysis.
Cronbach’s alpha was used to estimate instrument reli-
ability. Confirmatory factor analysis was used to corrobo-
rate that the factor structure of AQ-27-I was the same as the
one identified for the original version: path analysis is an
extension of the regression model, used to test the fit of the
correlation matrix against two or more causal models. The
model is usually depicted in a circle-and-arrow figure in
which single-headed arrows indicate causation.
Model fitness was assessed using the following indices of
fit: v2, goodness of fit index (GFI [ 0.90), root mean square
error of approximation (RMSEA \ 0.10) and adjusted
goodness of fit index (AGFI [ 0.90). The same indices
were also combined with beta’s to test the path model. The
test–retest reproducibility was evaluated using the intraclass
correlation coefficient (ICC), and the value of 0.65 was
accepted as adequate reliability for a group of patients.
Results
Socio-demographic characteristics
Table 1 summarizes the socio-demographic characteristics
of the participants. Age of the sample ranged from 18 to
89 years (mean = 40.15, SD = 16.36). The participants
were equally distributed for gender, 82.7% had at least a
high school education (50.5% attended high school and

26.6% university); 9.32% of the sample belonged to the
health professional group (psychiatrists, residents in psy-
chiatry, graduate nurses and psychologists), 18.69% were
students, and the remaining population were included into
the ‘‘other profession’’ group (including unemployed,
employed, housewives, and pensioners).
Confirmatory factor analysis
The relationship related to attributions of personal
responsibility for mental illness is provided in Fig. 1. As
described in Weiner’s attribution theory [37], the 12 items
were defined as loading in six different first order latent
factors: Personal Responsibility (10, 11, 23), Pity (9, 22,
27), Help (8, 20, 21), Anger (1, 4, 12), Coercion (5, 14, 25)
and Segregation (6, 15, 17). Fit estimates partly supported
the findings, although v2 (120) = 233.927 (P \ 0.001)
does not support fit the v2/df ratio = 1.95. The GFI =
0.893 and AGFI = 0.848 are both little below criterion
levels. RMSEA on the other hand was satisfying (0.09).
We decided against dropping out items and redoing the
structural equations for two reasons. Our major goal was
to determine whether the Italian model mirrored the

American; these fit indicators are equivalent on the matter.
Secondly, each of the AQ items loaded significantly into
the corresponding latent factor. Hence, there was no clear
choice about development of subsequent structural equa-
tions. Correlations between factors are much more robust,
however. These are provided in the figure. The model
representing attribution and pity was not significantly
associated. However, betas for attribution, anger, coercion
and segregation were large, ranging from 0.22 to 2.27.
Indices for the path model representing the theory of
dangerousness [13, 14] are presented in Fig. 2. According
to this theory, the nine factors were defined as loading in
three different first order latent factors: Dangerousness
(2,13,18), Fear (3,19,24) and Avoidance (7,16,26). Chi
square did not support fit [v2 (24) = 85.384 (P \ 0.001),
v2/df ratio = 3.56]. However, the GFI = 0.919 and
RMSEA = 0.109 met criteria; AGFI = 0.848 is only a
little below criterion level. All the AQ items loaded sig-
nificantly into corresponding factors. Correlations between
factors were very large, ranging from 0.50 to 0.84.
Internal consistency and test–retest reliability
Internal consistency reliability for the AQ-27-I as a whole
was 0.818. Cronbach’s alpha coefficients for each factor
are displayed in Table 2. Satisfactory reproducibility was
indicated by the acceptable test–retest reliability, measured
as intraclass coefficient, whose total value was 0.82.
Intraclass coefficients for each factor are also displayed in
Table 2.
Discussion
As awareness of the clinical significance of stigma in
mental health grows, so does the need for valid and reliable
instruments to measure the phenomenon, from the patient,
general public, and helping professional’s perspective. The
aim of this study was to translate and examine the reli-
ability and validity of the Italian version of the AQ-27
(AQ-27-I). To our knowledge only one previous study has
ever examined stigmatizing attitudes toward mentally ill
patients in Italy using a standardized, validated Italian
questionnaire [28, 29].
The AQ-27-I, in its original English version, follows
well-articulated theoretical constructs, considering
responsibility and dangerousness factors and their influence
on stigma severity. Moreover, by changing the initial
vignette presentation depicting ‘‘Harry’’, it allows adapta-
tion to specific aspects, such as familiarity and presence of
violent behaviour, to explore their secondary contribution
to stigmatizing attitudes [36].
To validate the AQ-27-I, confirmatory factor analyses
and path analyses were carried out. General fit indices were
equivocal though individual AQ items loaded significantly
into corresponding latent factors [36, 40–42]. Betas

representing relationships among factors mostly paralleled
findings from studies conducted with the English version. In
terms of the attribution model, attributing blame led to anger
which increased endorsement of coercion and segregation.
In the second path model, dangerousness hugely predicted
fear which, in turn, was associated with avoidance.
The overall Cronbach a values for AQ 27-I were highly
acceptable, indicating satisfactory internal consistency of
the instrument. Regarding stability of the instrument, the
test–retest reliability of the scores was also highly
acceptable, with ICC scores for the total scale and sub-
scales exceeding 0.65 (excepted for Anger, Coercion and
Avoidance).
There are several limitations to be addressed, partially
cautioning generalizability of our findings. Firstly, Cron-
bach’s a coefficient limited values in Responsibility,
Anger, Coercion and Avoidance factors suggest that other,
less well identified variables could have an important role
in the variance left. Secondly, the questionnaire has been
tested on an opportunistic sample, which might not be fully
representative of the Italian population. Nevertheless,
comparing socio-demographic features of our sample with
2008 national statistics [43], no differences were found in
mean age and male/female ratio; the level of school edu-
cation was higher in the study sample than the national
average: this limits generalizability of findings due to the
well-known impact of educational level on stigma and it is
possible that stronger stigmatizing attitudes would be seen
in a less educated sample. Finally, it is possible that dif-
ferences in cultural background and history of psychiatric
care between Italy and the US, where the original version
of the questionnaire was developed, might require a more
tailored set of questions closely related to the Italian cul-
tural context. The deeply rooted community-based tradition
of psychiatric health care in Italy might have contributed to
a higher level of tolerance and acceptance toward psychi-
atric patients, with strong emotional, ideological and
political forces driving away from the previous institutional
model. On the other hand, it has been suggested that new
and more subtle discriminating behaviours might have
arisen by the integration of mentally ill patients in the
society [44, 45]. These new potentially stigmatizing atti-
tudes remain to be explored and require further examina-
tion on larger and more representative key-populations,
also further contributing to the validation of AQ-27. The
availability of a valid Italian version could allow more
culturally specific research, in larger and more various
clinical settings, hopefully providing cross-cultural com-
parisons and examining whether the unique community-
based treatment tradition in Italy results in different public
attitudes toward psychiatric patients [41, 42].
Our study aimed at translating and validating the Italian
version of AQ-27, a popular and operationalized
instrument designed to explore stigma in psychiatry. Its
availability for use in different settings (i.e. General Hos-
pital, Primary Care, and Mental Health Services) and its
adaptability to different clinical scenarios or respondents
might help elucidate the complex and still poorly docu-
mented phenomenon of stigma in mental illness.
Conflict of interest All authors declare that there are no financing
arrangements or payments that might be considered a conflict of
interests related to the present paper.
