    choices about mental illness and hence can act as the first

    step towards attitudinal and behavioural change (Corrigan,

    2004b). Corrigan and Penn (1999) have shed light on this

    strand of research by identifying four key components of

    successful educational interventions: the provision of

    personal information about the patient with mental illness;

    a direct attack of myths; an increase in empathy levels bysimulation; and an in-depth discussion on the topic. In

    addition, to increase the effectiveness of any anti-stigma

    approach, including an educational one, the intervention

    should target specific population groups (Corrigan, 2004a;

    Thornicroft, 2006).

    With regard to young population groups, converging

    evidence has supported that school-based anti-stigma initi-

    atives may constitute an effective vehicle for advancing

    knowledge about mental illness and improving attitudes

    towards the patients who suffer from it (Pinfold, Toulmin,

    Thornicroft, & Huxley, 2003; Rickwood, Cavanagh, Leigh,

    & Sakrouge, 2004; Schachter et al., 2008; Schulze, Richter-

    Werling, Matschinger, & Angermeyer, 2003; Stuart, 2006).

    Children and adolescents have emerged as a promising tar-

    get group for anti-stigma interventions, because throughout

    this developmental period attitudes to mental illness are

    consolidated. Various studies have demonstrated that chil-

    dren do not yet have a clear idea of what mental illness

    denotes (Corrigan & Watson, 2007), and that the person-

    ality traits that constitute the foundation for stereotype

    endorsement are not well entrenched until adolescence

    (Flavell, Miller, & Miller, 2001). Therefore, by altering

    unfavourable and rejecting attitudes among children and

    adolescents, one can prevent them from becoming adults

    who hold traditional stereotypical beliefs about people withmental illness and hence stigmatize them. Furthermore,

    addressing children and adolescents merits special atten-

    tion in light of the high prevalence of psychiatric disorders

    in this population (Schulze et al., 2003; Stuart, 2006).

    Evidence from the World Health Organization (2005) sug-

    gests that while one in five adolescents experiences a men-

    tal disorder, only 20% of them will seek professional help

    for fear of being labelled as mentally ill. This finding is

    important given that many psychiatric disorders emerge

    during adolescence, such as obsessive compulsive disorder

    (Maggini et al., 2001) and schizophrenia (Thomsen, 1996).

    In spite of the significance of this type of intervention,the literature on the effectiveness of anti-stigma initiatives in

    children and adolescents is scarce (Schachter et al., 2008).

    The limited number of studies on the topic have indicated

    that prior to the intervention, the majority of students are

    either unsure about the correctness of stereotypical views

    about patients with psychiatric disorders or less rejecting

    towards them in comparison to adults; with variables such

    as gender and familiarity with mental illness playing a

    prominent role in stigma endorsement (Corrigan et al., 2005;

    Ng & Chan, 2002; Pinfold et al., 2003; Schulze et al., 2003;

    Watson et al., 2004). In terms of effective interventions,

    education has been shown to yield improvements of short

    duration in attitudes towards mental illness in adolescents

    (Ng & Chan, 2002; Schulze et al., 2003; Watson et al., 2004;

    Williams & Pow, 2007). However, social distance measures,

    which constitute the most widely used index of stigmatiza-

    tion (Jorm & Oh, 2009), have been found to display the

    greatest resistance to change upon completion of the edu-cational intervention (Pinfold et al., 2003; Schulze et al.,

    2003). Recent evidence has indicated that when personal

    contact with a patient with mental illness, either in vivo or in

    a video, is added to education, attitudes towards patients are

    improved and desired social distance from them is remark-

    ably reduced (Chan, Mak, & Law, 2009; Schachter et al.,

    2008; Stuart, 2006)

    The anti-stigma programme, run by the University

    Mental Health Research Institute, has designed and imple-

    mented a series of anti-stigma interventions in adolescents

    within the framework of World Psychiatric Association

    Open the Doors global program against stigma and dis-

    crimination because of schizophrenia. Due to the focus of

    the programme on schizophrenia at the time (Economou,

    Gramandani, Richardson, & Stefanis, 2005; Economou,

    Richardson, Gramandani, Stalikas, & Stefanis, 2009), the

    interventions addressed the stigma surrounding severe

    mental illness in general and schizophrenia in particular.

    The aim of the intervention was to advance students

    knowledge about schizophrenia, to improve their attitudes

    towards the patients who suffer from it and to reduce their

    desired social distance levels. Consistent with this, the

    intervention aimed to yield changes in all three dimensions

    of stigma, namely knowledge, attitudes and behaviour

    (Thornicroft, 2006); however, changes in the behaviourdimension were assessed indirectly by employing a social

    distance measure, which constitutes a proxy of behavioural

    intention. To achieve its aims, the initial intervention proto-

    col incorporated a combined education and personal con-

    tact strategy, in line with the literature underscoring its

    effectiveness (Chan et al., 2009; Schachter et al., 2008;

    Stuart, 2006). However, a number of objections and com-

    plaints on the part of parents, school principals and teachers

    necessitated changes in the protocol resulting in the elimi-

    nation of the personal contact components. Therefore, in its

    final form, the intervention was largely educational in

    nature but it did entail some narratives of patients withschizophrenia read by a mental health professional. To opti-

    mize the interventions effectiveness, its content was based

    on Corrigan and Penns (1999) recommendations. In the

    context of patient narratives, personal information about

    the patient and his/her aftercare was provided to students,

    the myths that surround schizophrenia were attacked one

    by one, students empathic feelings towards patients were

    enhanced by role-play exercises and an in-depth discussion

    on the topic was conducted. Consistent with these, the pre-

    sent study set the twofold aim of exploring high school

    students beliefs, attitudes and desired social distance

    students. The self-reported instrument comprised two parts,

    one exploring beliefs and attitudes towards schizophrenia

    and PwS, and another addressing the degree of desired

    social distance from them. The beliefs and attitudes part

    encompassed 11 items, rated on a four-point Likert scale

    (1 = never, 4 = always), with some of them being nega-

    tively phrased in order to avoid response bias (e.g. PwScan be creative). Similarly, the social distance section of

    the instrument consisted of seven items, rated on a four-

    point Likert scale (1 = definitely no, 4 = definitely yes),

    with some of them being also negatively phrased in order to

    avoid bias (e.g. Would you invite someone with schizo-

    phrenia to your party?). For both sections, a composite

    score was calculated by adding up the responses to all

    items, after having reversed the negatively phrased items

    (subtracting their rating from 5). For both composite scores,

    higher values indicated more stereotypical beliefs and neg-

    ative attitudes towards schizophrenia and PwS as well as a

    greater desired social distance from them. A reliability

    analysis utilizing Cronbachs indicated moderate internal

    consistency for both composite scores (for beliefs, =

    0.60.76 and for social distance, = 0.760.78).

    Statistical analysis

    For a descriptive analysis of students baseline beliefs,

    attitudes and social distance answers, percentages of

    pooled responses for each item were used. For the analysis

    of associations between gender and familiarity with men-

    tal illness on the one hand, and baseline beliefs, attitudes

    and social distance measures on the other, two composite

    scores were calculated: one for beliefs and attitudes andanother for social distance. A t test for independent sam-

    ples was then used to reveal any differences. In order to

    evaluate the short-term effect of the intervention on beliefs,

    attitudes and social distance, the mean baseline score for

    each item was compared to the mean post-intervention

    score for the corresponding item by using a repeated

    measures t test analysis. Similarly, to evaluate the long-

    term effectiveness of the intervention, a pairwise ttest was

    used between the baseline mean scores for each item and

    its corresponding follow-up score. The rationale for con-

    ducting item analysis in the study was to identify which

    beliefs, attitudes and social interactions displayed thegreatest change and which displayed the least. In addition,

    for the beliefs and attitudes section of the instrument, the

    reliability analysis demonstrated wide variability in the

    values of Cronbachs (range 0.60.76) and as a result of

    this, analysis on a scale level was contentious and hence

    was avoided. On the contrary, as social distance scales

    have been empirically supported in terms of their psycho-

    metric properties, the results pertaining to the social dis-

    tance items were analysed on a scale level as well. The

    effect of the intervention on the social distance composite

    score was assessed using repeated measures ANOVA.

    A multiple linear regression model on follow-up scores

    was used in order to identify which factors could signifi-

    cantly predict students follow-up results.

    Results

    The two groups (control and intervention) did not displaysignificant differences in terms of their basic demographic

    variables, such as gender, age and personal acquaintance

    with someone with serious mental illness (p > .05).

    Baseline beliefs, attitudes and social distance

    The two groups did not differ significantly with regard to

    the distribution of their baseline responses to all items (p >

    .05). To increase the statistical power of the analysis, data

    were pooled in such a way that two categories were formed:

    always/often and seldom/never for the beliefs and atti-

    tudes section and definitely/probably yes and definitely/probably no for the social distance section.

    The majority of students espoused the stereotypical

    view of a PwS talking to him/herself or shouting in city

    streets (80.1%). Similarly, a high percentage of students

    reported that PwS always/often suffer from split or multi-

    ple personalities (70.9%) or cannot work at regular jobs

    (81.2%). Furthermore, one in two viewed PwS as danger-

    ous (51.25% believed this is always/often the case) and

    a public nuisance (50.5% answered always or often).

    Interestingly, a relatively high percentage of the sample

    held the positive view that PwS can be creative (67.15%),

    can be successfully treated outside of the hospital in the

    community (67.95%) and need prescription drugs to con-trol their symptoms (72.6%).

    In terms of social distance items, the vast majority of

    students would not fall in love with a PwS (86.8%) nor

    would share their room with him/her during a school excur-

    sion (81.85%). Furthermore, one in two would not invite a

    PwS to their party (41.4% would probably/definitely do

    so). Nonetheless, only 35.55% would be upset or disturbed

    to be in the same class with a PwS, 46.75% would be afraid

    to talk to him/her, while 70.5% would start a friendship

    with him/her.

    When composite scores were calculated, no gender

    effect on beliefs, attitudes and social distance at baselineemerged (t= 0.3,p > .05 for the beliefs and attitudes section

    and t= 0.89, p > .05 for the social distance section). By

    contrast, previous contact with a person with a severe men-

    tal illness was found to differentiate in a significant manner

    the social distance scores at baseline (t= -2.57,p < .01).

    Intervention effect

    To evaluate the effectiveness of the intervention, students

    answers before and after the workshop were compared for

    the experimental and control groups separately.

    Short-term effect: Upon completion of the intervention.

    For the experimental group, beliefs and attitudes were

    improved in all items but one (PwS can be successfully

    treated without drugs using psychotherapy; Table 1) andthis cannot be explained by variables other than the inter-

    vention, since the control group did not manifest the same

    pattern of results (p > .05 for all items). Nonetheless, even

    upon completion of the intervention, students still sub-

    scribed to some negative stereotypes about PwS. Specifically,

    the majority of students still believed that PwS can be seen

    talking to themselves or shouting in city streets (mean score

    = 3, which is higher than the neutral point 2.5 and closer to

    the extreme always) and cannot hold a job in an open

    labour market (mean score = 1.83, which is below the

    neutral point 2.0 and closer to the extreme never).

    Likewise for the social distance items, there was a

    significant change in all items for the experimental group

    (Table 2), whereas no significant changes were recorded for

    the control group (p > .05 for all items). However, evenafter the intervention the mean score for the item Would

    you fall in love with a PwS? was 1.88, which is below the

    neutral point 2.0 and closer to the extreme definitely no.

    Long-term effect: Follow-up. In order to address the long-

    term effect of the intervention, the answers at the pre-inter-

    vention and follow-up time points were compared. With

    regard to students beliefs and attitudes to PwS, a

    gradual worsening was observed from post-intervention

    mean item scores to the corresponding follow-up scores.

    Nonetheless, the statistical analysis revealed that follow-up

    scores were significantly different from baseline scores on

    Table 1. Mean item scores for beliefs and attitudes section at baseline, post-intervention and follow-up time points.

    all items apart from two (PwS hear voices and PwS can be

    successfully treated outside the hospital, in the community),

    lending support to the long-term effectiveness of the inter-

    vention. Concerning desired social distance from PwS, of the

    seven items of the section, significant differences between

    baseline and follow-up measures emerged for only three:

    being classmates with a PwS, inviting him/her to a party and

    sharing a room in a school excursion. For the remaining

    items, the improvement observed at post-intervention was

    not maintained. For the control group, no significant differ-

    ences were observed between the pre-intervention and fol-

    low-up measures for any item (p > .05).

    When social distance was analysed on a scale level, a

    repeated measures ANOVA with post hoc comparisons

    using the Bonferroni correction revealed a significant dif-

    ference between the baseline and post-intervention social

    distance scores (M = 18.36, SD = 2.46 and M = 15.63,SD = 2.67, respectively), indicating a positive short-term

    effect of the intervention; however, no significant differ-

    ence was discerned between the baseline and the follow-up

    scores (follow-up M= 17.96, SD = 2.23), indicating that

    one year after the intervention, the students returned to their

    baseline social distance levels (Figure 1).

    Positive baseline scores and female gender were the

    only two variables that predicted positive attitudes and

    lower social distance scores at follow-up (R2 = 5.1%,F=

    2.79,p < .05 for beliefs and attitudes composite score and

    R2 = 20.1%, F= 11.41,p < .001 for social distance com-

    posite score).

    Discussion

    The findings of the present study lend support to the imper-

    ative need for developing effective anti-stigma interven-

    tions targeting children and adolescents. Prior to receiving

    any intervention, students were found to hold stereotypical

    beliefs and rejecting attitudes towards PwS. The majority

    of them espoused the belief that PwS are dangerous, cannot

    work, speak to themselves or shout in city streets, suffer

    from split personality and constitute a public nuisance. A

    similar pattern of results has been recorded in the adult

    population in Greece (Economou, Gramandani et al., 2005;

    Economou et al., 2009). In spite of dissimilarities in the

    sampling methods between the current study and those

    carried out in adults, one can observe that adults are more

    stigmatizing and negative towards PwS. Among the adoles-

    cents, 51.25% held the view that PwS are dangerous in con-

    trast to 70.1% of adults, after controlling for urbanruraldifferences. Similarly, 50.5% of adolescents were found to

    deem PwS a public nuisance, while this figure is 62.9% in

    adults. This finding is consistent with other studies that

    have indicated that adolescents hold more favourable

    attitudes than adults to people with mental illness (Schulze

    et al., 2003; Watson et al., 2004).

    Comparing the findings of the present study to those in

    other countries, the young population in Greece appears to

    be very distancing towards PwS. Schulze et al. (2003)

    report that only 6.5% of students (average percentage

    between the experimental and control group) stated that

    they would be afraid to talk to a PwS, a rate that reaches

    as high as 46.75% in our sample. Furthermore, while in

    Germany, 20.5% of students admitted that they could fall in

    love with a PwS, in Greece the rate is slightly lower, i.e.

    13.2%. Interestingly, while adolescents in Greece express

    greater desire for social distance from PwS in comparison

    to their counterparts in Germany, the difference between

    the two countries is more striking in items concerning

    superficial encounters with the patient. In particular, the

    difference in percentages between the two countries with

    regard to the item Would you be afraid to talk to a PwS?

    reaches 26.75%. Adolescents high levels of stigmatization

    against PwS in Greece may be attributed to the Greek ori-

    gin of the word schizophrenia and the strongly stigmatiz-ing media portrayals of PwS in the country (Economou,

    Kourea et al., 2005). In Greek society the term schizophre-

    nia is linked to fear and devastation and even mental health

    professionals are avoiding its use by replacing it with that

    of psychosis. Therefore, it is not surprising that while

    most of the adolescents are oblivious to what the word

    denotes, based on its literal meaning (i.e. split mind), they

    usually speculate that the term is germane to a split person-

    ality or a fragmented mind, both of which are mainly

    associated with the traits of violence, dangerousness and

    unpredictability (Economou et al., 2009). Furthermore,

    adolescents in Greece are continuously exposed to stigma-tizing portrayals of PwS in the media, especially on TV and

    at the cinema. An illustration of this point is the film Texas

    Chainsaw Massacre, which has been repeatedly broadcast

    on TV and in the cinema but which in Greece was released

    as The Schizophrenic Killer with the Chainsaw. The very

    stigmatizing Greek title capitalized on the association

    between a schizophrenic patient and a serial killer in lay

    peoples mind and therefore strengthened the stereotype of

    dangerousness pertaining to PwS. It is noteworthy that

    during the anti-stigma intervention when students were

    asked about their sources of information with regard

    to severe mental illness, the majority identified TV as

    their primary source and spontaneously referred to The

    Schizophrenic Killer with the Chainsaw.

    Compared to the literature that points towards gender

    and familiarity with mental illness as factors that play a

    prominent role in stigma endorsement, the present study

    found no gender effect for baseline measures but a signifi-

    cant impact of personal experience with mental illness. Theinfluence of gender on beliefs and attitudes to people with

    mental illness has yielded conflicting results, with some

    studies reporting that girls are more positive towards the

    patients (Ng & Chan, 2002; Williams & Pow, 2007) and

    some others failing to find a significant difference (Schulze

    et al., 2003). Similarly, familiarity with mental illness has

    been found to be associated with both more positive (Pinfold

    et al., 2003) and more negative attitudes (Corrigan et al.,

    2005). An interesting finding of the study was that only

    female gender and baseline scores could predict follow-up

    scores. While this is in line with the findings of an earlier

    study (Pinfold et al., 2003), it is surprising that personal

    experience with mental illness had a non-significant contri-

    bution to the model. A possible explanation for this is the

    diversity in the intensity of familiarity, which can vary from

    a person watching TV portrayals of mental illness to having

    a distant or a close relative suffering from a psychiatric dis-

    order (Corrigan, Backs-Edwards, Green, Lickey-Diwan, &

    Penn, 2001). It is therefore plausible that the educational

    intervention increased students familiarity with mental ill-

    ness and as a result of this, the differences that emerged at

    baseline were compensated for at follow-up.

    In terms of the effectiveness of the educational interven-

    tion in modifying beliefs, attitudes and desired social dis-

    tance from PwS, immediately upon its completion and at a12-month follow-up, the results that emerge support the

    existing literature. In line with other studies (Ng & Chan,

    2002; Schulze et al., 2003; Watson et al., 2004), the educa-

    tional intervention was found to have a positive impact as

    indicated by an improvement in attitudes and a remarkable

    decrease in the frequency of stereotypical beliefs and in the

    degree of desired social distance. With regard to the follow-

    up results, the picture is more diverse. On the one hand, sig-

    nificant improvements in adolescents beliefs and attitudes

    after the intervention were largely maintained 12 months

    after its completion. On the other, the improvement recorded

    on the social distance items upon completion of the inter-vention was not maintained at follow-up, where students

    almost returned to their baseline answers. In line with

    Pinfold et al. (2003), it appears that social distance is more

    resistant to change than other measures of stigmatization

    and possibly necessitates a different approach for targeting

    it. The intervention of the present study was brief and lacked

    a personal contact component. As a result, an anti-stigma

    intervention aiming at decreasing adolescents desired social

    distance from PwS should consider involving patients and

    allow for an interaction between them and the adolescents.

    Furthermore, this intervention should be longer and con-

    stantly delivered throughout the developmental period of

    stereotype formation and consolidation. In this way, even if

    adolescents are exposed to stigmatizing portrayals of people

    with mental illness, in the media for example, their personal

    contact with a number of PwS in the classroom coupled with

    the appropriate education will enable them to stand critically

    towards the vehicles that perpetuate the stigma attached to

    mental illness. Health promotion programmes, like thoseimplemented at the participating schools, should become an

    integral part of the high school curriculum and should be

    delivered throughout school years.

    Limitations

    The major shortcoming of the present study was its inabil-

    ity to extrapolate its findings to a representative sample of

    adolescents throughout the country. The sample was

    restricted to urban areas and only schools with a health pro-

    motion programme in their curriculum took part. Given

    that the preponderance of psychiatric stigma in Greek

    urban areas has been found to be lower compared to rural

    areas (Economou et al., 2009) and that students from

    schools with a health promotion programme in their cur-

    riculum are possibly more tuned and sensitized to issues of

    health, stigma endorsement might have been stronger if a

    more diverse sample was attained. This assumption is

    further supported by the opposition expressed by many

    schools to deliver any kind of intervention related to severe

    mental illness to their students. In Greece, talking about

    severe mental illness, and especially about schizophrenia,

    to students is still a major taboo and demonstrates further

    how entrenched psychiatric stigma is in the Greek culture.

    Therefore, a future study aiming at broadening its recruit-ment scope would cast light on adolescents degree of

    stigma endorsement and subsequently on the potential of

    an anti-stigma intervention to fight it.
