RESUMO

BACKGROUND: Attachment theory offers an important framework for understanding interpersonal interaction experiences. In the present study, we examined the neural correlates of attachment patterns and oxytocin in schizophrenic patients (SZP) compared to healthy controls (HC) using fMRI. We assumed that male SZP shows a higher proportion of insecure attachment and an altered level of oxytocin compared to HC. On a neural level, we hypothesized that SZP shows increased neural activation in memory and self-related brain regions during the activation of the attachment system compared to HC. METHODS: We used an event-related design for the fMRI study based on stimuli that were derived from the Adult Attachment Projective Picture System to examine attachment representations and their neural and hormonal correlates in 20 male schizophrenic patients compared to 20 male healthy controls. RESULTS: A higher proportion of insecure attachment in schizophrenic patients compared to HC could be confirmed. In line with our hypothesis, Oxytocin (OXT) levels in SZP were significantly lower than in HC. We found increasing brain activations in SZP when confronted with personal relevant sentences before attachment relevant pictures in the precuneus, TPJ, insula, and frontal areas compared to HC. Moreover, we found positive correlations between OXT and bilateral dlPFC, precuneus, and left ACC in SZP only. CONCLUSION: Despite the small sample sizes, the patients' response might be considered as a mode of dysregulation when confronted with this kind of personalized attachment-related material. In the patient group, we found positive correlations between OXT and three brain areas (bilateral dlPFC, precuneus, left ACC) and may conclude that OXT might modulate within this neural network in SZP.

RESUMO

BACKGROUND: Among adolescent girls, anorexia nervosa (AN) and major depression (MD) are common and often comorbid mental health problems. Both disorders are characterised by difficulties in recognising and verbalising (alexithymia) as well as regulating one's emotions, but research in adolescent patients is scarce and little is known about the relation between alexithymia and difficulties in emotion regulation. The aims of this study were to investigate alexithymia and emotion regulation skills in adolescents with AN, adolescents with MD, and healthy adolescents, and to determine whether alexithymia functions as a predictor for emotion regulation skills. METHODS: Emotion regulation strategies, alexithymia, and depressive symptoms were assessed by questionnaire measures in 12-18 year old girls with AN (n = 26), girls with MD (n = 25), and healthy girls (n = 35). Groups were compared with respect to the these variables and multiple regression analyses were calculated separately for adaptive and maladaptive emotion regulation strategies in order to examine if alexithymia predicted emotion regulation over and above age and depressive symptoms. RESULTS: Girls with AN or MD both reported using adaptive emotion regulation strategies less frequently and maladaptive emotion regulation skills more frequently as well as higher levels of alexithymia compared to healthy girls. Alexithymia positively predicted maladaptive emotion regulation strategies, while depressive symptoms negatively predicted adaptive emotion regulation strategies. CONCLUSIONS: The results suggest that different mechanisms may underlie the lack of adaptive and the surplus of maladaptive emotion regulation strategies in adolescent psychiatric patients.

RESUMO

BACKGROUND: Many people with mental illness perceive and experience stigma caused by other people's knowledge, attitudes, and behavior. The stigma can lead to patients' impoverishment, social marginalization, poor adherence to medication, and low quality of life, worsen the disease, decrease health-seeking behavior, and have a negative impact on socioeconomic well-being. Therefore, this study aimed to explore these issues. OBJECTIVE: To assess the magnitude and associated factors of perceived stigma among adults with mental illness in an Ethiopian setting. METHODS: A facility-based, cross-sectional study design with a consecutive sampling technique was employed from September 1 to 30, 2012. Data for perceived stigma were assessed by using the perceived devaluation-discrimination (PDD) scale from new or returning patients. The data was analyzed by using the Statistical Package for the Social Sciences (SPSS) version 20. The results were described with the frequency table, graph, mean, and standard deviation. Bivariate analysis was used to get candidate variables for multivariate logistic regression analysis. Variables with a P value of < 0.05 at multivariate analysis were considered statistically associated with perceived stigma. RESULTS: A total of 384 participants were interviewed and the response rate was 100%. The prevalence of high and low perceived stigma was 51% and 44%, respectively. Having substance use history (AOR=0.6, 95% CI: 0.4-0.9) and family support (AOR=2.5, 95% CI: 1.5-4.3) and medication side effects (AOR=0.6, 95% CI: 0.5-0.8) were associated statistically with higher perceived stigma of people with mental illness. CONCLUSION: Perceived stigma is a major problem of adults with mental illness in this outpatient setting in Ethiopia. Patients who had substance use and family support and medication side effects were more likely to have high perceived stigma. Therefore, screening and management of substance use, social support, and medication side effect should be strengthened for people with mental illness.

RESUMO

BACKGROUND: In the day clinic of the Department of Psychiatry and Psychotherapy of the LMU Munich, a multimodal therapy concept is offered. The goals of treatment are, in addition to the reduction of symptoms, an expansion of everyday life skills and the professional and social reintegration of patients. METHOD: The effectiveness of the therapeutic work was evaluated over a period of just under 3 years. Both the therapist and the patients themselves assessed the success of the treatment. RESULTS: Subjective measures: The affective (BDI: 17.45 at the beginning vs. 9.38 at the end) and the anxiety symptoms (STAI: 49.51 at the beginning vs. 42.11 at the end) decreased. The quality of life (WHOQOL-Bref: 40.96 at the beginning vs. 62.50 at the end) increased. Performance (COPM: 3.81 at start vs. 6.91 at end) and satisfaction with it (COPM: 3.48 at start vs. 7.08 at end) improved. Physician's judgment: The global assessment of functioning (GAF: start of therapy 54.91 vs. end of therapy 68.14) and the clinical global impression (CGI: start of therapy 4.48 vs. treatment end 3.03) showed an improvement. All results were significant. CONCLUSION: The day clinic's treatment concept seems to work comprehensively, both in patients with depressive disorder and in patients with schizophrenic disease.

RESUMO

Decision-making in groups is a remarkable and decisive element of human societies. Humans are able to organize themselves in groups, engage in collaborative decision-making processes and arrive at a binding agreement, even in the absence of unanimous consent. However, the transfer of decision-making autonomy requires a willingness to deliberately expose oneself to the decisions of others. A lack of trust in the abilities of others or of the underlying decision-making process, i.e. public trust, can lead to a breakdown of organizations in political or economic domains. Recent studies indicate that the biological basis of trust on an individual level is related to Oxytocin, an endogenous neuropeptide and hormone, which is also associated with pro-social behavior and positive conflict resolution. However, little is known about the effects of Oxytocin on the inclination of individuals to form or join groups and to deliberately engage in collaborative decision-making processes. Here, we show that intranasal administration of Oxytocin (n = 60) compared to placebo (n = 60) in males causes an adverse effect on the choice for forming groups in the presence of a competitive environment. In particular, Oxytocin negatively affects the willingness to work collaboratively in a p-Beauty contest game, whereas the effect is most pronounced for participants with relatively high strategic sophistication. Since our data provide initial evidence that Oxytocin has a positive effect on strategic thinking and performance in the p-Beauty contest game, we argue that the adverse effect on group formation might be rooted in an enhanced strategic sophistication of participants treated with Oxytocin.

RESUMO

Antipsychotics are effective in treating schizophrenia but may lead to a higher cardiovascular risk due to QTc prolongation. Besides drugs, genetic and clinical factors may contribute to QTc prolongation. The aim of this study is to examine the effect of candidate genes known for QTc prolongation and their interaction with common antipsychotics. Thus, 199 patients were genotyped for nine polymorphisms in KCNQ1, KCNH2, SCN5A, LOC10537879, LOC101927066, NOS1AP and NUBPL. QTc interval duration was measured before treatment and weekly for 5 weeks while being treated with risperidone, quetiapine, olanzapine, amisulpride, aripiprazole and haloperidol in monotherapy. Antipsychotics used in this study showed a different potential to affect the QTc interval. We found no association between KCNH2, KCNQ1, LOC10537879, LOC101927066, NOS1AP and NUBPL polymorphisms and QTc duration at baseline and during antipsychotic treatment. Mixed general models showed a significant overall influence of SCN5A (H558R) on QTc duration but no significant interaction with antipsychotic treatment. Our results do not provide evidence for an involvement of candidate genes for QTc duration in the pathophysiology of QTc prolongation by antipsychotics during short-term treatment. Further association studies are needed to confirm our findings. With a better understanding of these interactions the cardiovascular risk of patients may be decreased.

RESUMO

The ability to inhibit inappropriate responses and suppress irrelevant information is a core feature of executive control. In this study, we provide a detailed analysis of prepotent response inhibition and interference in patients with schizophrenia. To further test the role of genetic factors and subclinical schizophrenia-like traits, we additionally studied clinically unaffected, first-degree relatives of schizophrenia patients and assessed dimensions of schizotypy in both relatives and healthy controls. Inhibition and interference control were assessed using a battery comprising the antisaccade, Stroop, stop signal, go/no-go, flanker, and Simon tasks. Schizophrenia patients differed from both relatives and controls in making more errors on the antisaccade task and having longer response times on the Stroop task, especially the incongruent condition. Patients also had general, that is, condition independent, increases in reaction times on the go/no-go and flanker tasks and made more errors on the flanker and Simon tasks, suggesting general performance impairments independent of inhibitory demand. Relatives were characterized by hypometric antisaccade amplitude gain despite normal prosaccades, suggesting a selective deficit in non-standard sensorimotor transformations. Schizotypy was correlated with inhibitory performance across a number of tasks in both relatives and controls. Generally, these effects were independent of verbal intelligence levels. Overall, the findings point to rather selective impairments of inhibitory control in the schizophrenia spectrum and confirm a previously observed deficit in antisaccade spatial accuracy as an endophenotype of schizophrenia.

RESUMO

Introduction: The shortage of trained manpower in the field of mental health remains a significant obstacle to the treatment of people with mental illnesses in low and middle-income countries. In 2010, a new Master of Science in Integrated Clinical and Community Mental Health (MSc ICCMH) program for non-physician clinicians was established at Jimma University to address this shortage in Ethiopia. This study aimed to assess the competency, satisfaction, and involvement level of graduates of the program. Methods: A cross-sectional study was conducted among the graduates of the program. Data were collected with a semi-structured, self-administered questionnaire that was developed for the study. Responses were recorded on a Likert scale to assess graduates' competency and satisfaction level. The quantitative data were summarized by descriptive statistics, including means, standard deviations, and frequencies. Qualitative data were transcribed and analyzed thematically. Result: Until June 2015, 32 trainees had graduated from the MSc ICCMH program; 87.5% (n=28) of these graduates participated in the study. Almost all (96.4%, n=27) graduates were working in public institutions. The majority (75%, n=21) were directly engaged in the clinical care of patients. Also, two-thirds of the graduates (67.9%, n=19) were involved in mental health research. All of the graduates felt confident in conducting psychiatric assessments of adults and identifying and managing common mental disorders (100%, n=28). Similarly, 100% (n=28) of the graduates reported that they felt confident in identifying and managing severe mental illnesses. Conclusions: The outcome of the program is a considerable workforce of skilled mental health professionals. The majority of graduates were retained within the public mental health service. Brain drain does not appear to be a challenge among non-physician mental health specialists. The findings on the self-perceived competencies mirror the amount of clinical exposure during the training. With a minimal revision of the curriculum, the level of satisfaction and competencies can be enhanced.

RESUMO

INTRODUCTION: NEUROD2 is a neurospecific helix-loop-helix transcription factor which has an impact on the regulation of glutamatergic and GABAergic genes. We investigated an association of NEUROD2 with neurocognitive dysfunctions in schizophrenia and schizoaffective disorder patients before and during treatment with different second-generation antipsychotics. METHODS: Patients were genotyped for four different polymorphisms of the NEUROD2 gene ((rs9889354(A/G), rs1877032(C/T), rs12453682(C/T) and rs11078918(C/G)). Cognitive function was assessed at baseline and week 8. Results of individual neuropsychological tests were assigned to six cognitive domains (reaction time and quality; executive function; working, verbal and visual memory) and a general cognitive index. RESULTS: 167 patients were included in the study. The NEUROD2 exonic polymorphism rs11078918 showed significant associations with verbal memory and executive functions, whereas the NEUROD2 polymorphism rs12453682 was significantly associated with working and verbal memory, executive functions and with a cognitive index. Significant associations were found at baseline and after eight weeks. Moreover, significant associations between the change in neuropsychological test results during antipsychotic treatment and the NEUROD2 polymorphisms rs11078918 and rs12453682 were observed. CONCLUSIONS: Our findings suggest that the NEUROD2 gene could play a role in the pathophysiology of neurocognitive dysfunctions as well as in the change of cognitive symptoms under antipsychotic treatment in schizophrenia and schizoaffective disorder.

RESUMO

BACKGROUND: Signs of an inflammatory process have been described in major depression. METHODS: In a double-blind, randomized study of celecoxib or placebo add-on to reboxetine in 40 depressed patients, celecoxib treatment has beneficial effects. In order to evaluate the tryptophan/kynurenine metabolism and to identify predictors for remission, tryptophan (TRP), kynurenine (KYN), kynurenic acid (KYNA), and quinolinic acid (QUIN) were estimated in the serum of 32 patients before and after treatment and in a group of 20 healthy controls. RESULTS: KYN levels were significantly lower in patients (p = 0.008), and the QUIN/KYN ratios were significantly higher (p = 0.028). At baseline, the higher KYN/TRP ratio was predictive for remission during celecoxib add-on treatment (p = 0.04) as well as for remission in the overall patient group (p = 0.01). In the placebo group, remitters showed a higher KYNA/QUIN ratio (p = 0.032). In the overall group, remitters showed lower KYNA/KYN (p = 0.035) and QUIN/KYN (p = 0.011) ratios. The lower the formation of downstream metabolites, especially QUIN, the better the treatment outcome. CONCLUSION: The high KYN/TRP ratio predicted remission after treatment with celecoxib in this small sample of depressed patients. Eventually, the KYN/TRP ratio might be a marker for those patients, which benefit from an additional anti-inflammatory treatment.

RESUMO

BACKGROUND: Stigma towards people with mental illness (PWMI) can result in low self-esteem and isolation and threaten employment. Therefore, this study aimed to assess the magnitude of public stigma against PWMI and factors associated with it among Jimma town residents. METHODS: A community-based, cross-sectional, descriptive study was conducted in adult residents of Jimma town. Data were collected among 820 randomly selected residents with the interviewer-administered Community Attitudes toward the Mentally Ill (CAMI) scale. Linear regression analyses were performed to identify predictors of stigma against PWMI. RESULT: A total of 444 (54%) of the 820 respondents were females, and the mean (SD) age was 35 (8.5) years. The minimum and maximum possible values on each CAMI subscale were 10 and 50, respectively. The respondents had high scores for a stigmatizing attitude towards PWMI across all the subscales, as indicated by the mean (SD) scores: authoritarianism, 27.17 (4.96); social restrictiveness, 32.41 (4.20); benevolence, 35.34 (4.42); and community-based mental health ideology, 33.95 (5.82). Compared to housewives, private organization employees showed more autocratic and socially restrictive views (std. ß = 1.12, P<0.01). Single people had a lower social restrictiveness stigma score than married people (std. ß = -0.20, P<0.001), and participants' academic levels correlated inversely with the stigma score (std. ß = -0.12, P<0.001). A higher benevolence stigma score was observed among participants with no relationship with PWMI than among those with PWMI in their neighborhood (std. ß = 0.08, P< 0.046). CONCLUSION: The study revealed that a negative attitude towards PWMI is widespread. Therefore, there is a need to develop strategies to fight the stigma attached to PWMI at the community level.

RESUMO

This study explored the degree to which adult patients with Tourette syndrome (TS) exhibit particular attachment styles and the possible association between the underlying attachment dimensions and forms of aggression. Fifty-three TS patients (ages 17-72 years) and 54 matched healthy controls completed the Experiences in Close Relationships-Revised Scale (ECR-R) and the Aggression Questionnaire (AQ). The data were analysed with ANOVA F-tests, t-tests, and Pearson's correlation coefficient. TS patients showed significantly higher scores in relationship anxiety ( p < 0.001) and relationship avoidance ( p = 0.001) in the ECR-R and significantly higher aggression scores in the AQ ( p < 0.001). The total AQ score correlated significantly with the ECR-R dimension anxiety ( p < 0.001). These are the first findings on TS patients' attachment styles and anger symptoms. It remains unclear whether attachment anxiety and avoidance are risk factors for TS or whether the disorder itself induces attachment disorders. Prospective studies with detailed attachment interviews would help to explore this issue.

RESUMO

Quality of life (QOL) tends to be lower among the homeless than the general population, and traumatic events experienced on the streets have a negative impact on QOL. Low-income countries face a high number of street youth, yet little research has been performed so far on QOL, trauma, and posttraumatic stress disorder (PTSD) among this group. This study aimed at examining the QOL of a sample of Ethiopian street youth within a rehabilitation program and at exploring whether the street youth have experienced traumatic events and show posttraumatic stress symptoms. We interviewed 84 street youths with the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF) and the Diagnostic Interview for Children and Adolescents (DICA). Mean QOL scores differed significantly between the groups assessed at the beginning and at the end of the program (Cohen's d = 0.48). Eighty-three percent of the Ethiopian street youths had experienced traumatic events, and 25.0% met criteria for PTSD according to the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders. QOL did not differ between those with and without PTSD symptoms. These findings show the high rate of traumatic events among Ethiopian street youth and the importance for rehabilitation programs that focus on improving QOL. The results of the study may have cultural limitations.

RESUMO

OBJECTIVE: Impaired social functioning and autistic symptoms are characteristics of schizophrenia. The social hormones oxytocin (OT) and arginine-vasopressin (AVP) both modulate social interaction and therefore may be involved in the pathogenesis of schizophrenia. We investigated whether men with schizophrenia show altered OT and AVP levels compared with healthy controls (HC) and whether autism symptoms are associated with OT levels. METHODS: Forty-one men with non-acute schizophrenia and 45 matched HC were enrolled. Schizophrenia was assessed with the Positive and Negative Syndrome Scale (PANSS). Blood samples were collected on 2 days, and plasma OT and AVP levels were measured by ELISA immunoassay. RESULTS: The schizophrenia patients had significantly lower plasma OT levels than the HC; a similar trend was found for AVP. Plasma OT levels were associated with severe life events, fewer important attached persons, and a higher score on the PANSS negative scale; the most dominant PANSS items were 'preoccupation', 'emotional withdrawal', and 'passive/apathetic social withdrawal'. CONCLUSION: These findings support an association between the social hormones OT and AVP and schizophrenia. We suggest that OT metabolism may be altered in schizophrenia, but other possible causes for decreased plasma OT levels in schizophrenia patients include decreased OT synthesis, mRNA expression, and translation. Especially the 'autistic' symptoms of schizophrenia seem to be closely linked to an altered metabolism of OT, the 'attachment' hormone.

RESUMO

Pleckstrin homology domain (PH domain) comprises approximately 120 amino acids and is integrated in a wide range of proteins involved in intracellular signaling or as constituents of the cytoskeleton. This domain can bind phosphatidylinositol (3,4,5)-triphosphate and phosphatidylinositol (4,5)-biphosphate and proteins such as the ßγ-subunits of heterotrimeric G proteins and protein kinase C. Associations with psychiatric diseases have not been investigated yet. To identify genes involved in response to antipsychotics, mice were treated with haloperidol (1mg/kg, n = 11) or saline (n = 12) for one week. By analyzing microarray data, we observed an increase of pleckstrin homology domain containing 6 (PLEKHA6) gene expression. Furthermore, we genotyped 263 schizophrenic patients, who were treated monotherapeutically with different antipsychotics within randomized-controlled trials. Psychopathology was measured weekly using the PANSS for a minimum of four and a maximum of twelve weeks. Correlations between PANSS subscale scores at baseline and PANSS improvement scores after four weeks of treatment and genotypes were calculated by using a linear model for all investigated SNPs. We found associations between four PLEKHA6 polymorphisms (rs17333933 (T/G), rs3126209 (C/T), rs4951338 (A/G) and rs100900571 (T/C)) and different PANSS subscales at baseline. Furthermore two different polymorphisms (rs7513240 (T/C), rs4951353 (A/G)) were found to be associated with therapy response in terms of a significant correlation with different PANSS improvement subscores after four weeks of antipsychotic treatment. Our observation of an association between genetic polymorphisms of a protein of the PH domain and psychopathology data in schizophrenic patients might be indicative for an involvement of PLEKHA6 in the pathophysiology of schizophrenia and the therapy response towards antipsychotics.

RESUMO

OBJECTIVE: Surgeons and psychiatrists have been described as two contrary groups, the one healing by hands and the other by words. Empathy is needed in every physician-patient relationship. We tested whether (1) surgeons and psychiatrists show different levels of cognitive and emotional empathy; (2) measurements of cognitive and emotional empathy correlate with physician-specific empathy; and (3) gender, experience, and career choices are influencing factors. METHODS: 56 surgeons and 50 psychiatrists participated. We measured empathy with the Jefferson Scale of Physician Empathy (JSPE), cognitive empathy with the Reading the Mind in the Eyes Test Revised (RME-R6), and emotional empathy with the Balanced Emotional Empathy Scale (BEES). RESULTS: Male psychiatrists scored significantly higher than that of male surgeons (118.0±9.86 vs. 107.5±13.84; p=0.0006) in the JSPE. Analytically trained psychiatrists scored significantly higher in the JSPE than that of behaviorally trained psychiatrists (p=0.024, F test, adjusted for gender). Both the RME and the BEES correlated positively with the JSPE. CONCLUSION: Higher scores for empathy were found in male psychiatrists than in male surgeons. PRACTICE IMPLICATIONS: Further research is needed to learn about the effects of general medical training on empathy.

RESUMO

BACKGROUND: Public stigma against family members of people with mental illness is a negative attitude by the public which blame family members for the mental illness of their relatives. Family stigma can result in self social restrictions, delay in treatment seeking and poor quality of life. This study aimed at investigating the degree and correlates of family stigma. METHODS: A quantitative cross-sectional house to house survey was conducted among 845 randomly selected urban and rural community members in the Gilgel Gibe Field Research Center, Southwest Ethiopia. An interviewer administered and pre-tested questionnaire adapted from other studies was used to measure the degree of family stigma and to determine its correlates. Data entry was done by using EPI-DATA and the analysis was performed using STATA software. Unadjusted and adjusted linear regression analysis was done to identify the correlates of family stigma. RESULTS: Among the total 845 respondents, 81.18% were female. On a range of 1 to 5 score, the mean family stigma score was 2.16 (± 0.49). In a multivariate analysis, rural residents had significantly higher stigma scores (std. ß = 0.43, P < 0.001) than urban residents. As the number of perceived signs (std. ß = -0.07, P < 0.05), perceived supernatural (std. ß = -0.12, P < 0.01) and psychosocial and biological (std. ß = -0.11, P < 0.01) explanations of mental illness increased, the stigma scores decreased significantly. High supernatural explanation of mental illness was significantly correlated with lower stigma among individuals with lower level of exposure to people with mental illness (PWMI). On the other hand, high exposure to PWMI was significantly associated with lower stigma among respondents who had high education. Stigma scores increased with increasing income among respondents who had lower educational status. CONCLUSIONS: Our findings revealed moderate level of family stigma. Place of residence, perceived signs and explanations of mental illness were independent correlates of public stigma against family members of people with mental illness. Therefore, mental health communication programs to inform explanations and signs of mental illness need to be implemented.

RESUMO

BACKGROUND: In addition to economic and material burdens, caregivers of people with mental illness are exposed to psychosocial challenges. Self-stigma is among the psychological challenges that can be exacerbated by intrinsic and/or extrinsic factors. Caregivers' self-stigma can negatively influence the patients' treatment and rehabilitation process. The objective of this study was to measure the level and correlates of self-stigma among caregivers of people with mental illness. METHODS: An interviewer-administered cross-sectional study was conducted in the Jimma University Specialized Hospital Psychiatry Clinic in Ethiopia on a sample of 422 caregivers. Data were collected by trained nurses working in the clinic using a pretested questionnaire. Multivariate linear regression was performed to identify the correlates of self-stigma among caregivers of people with mental illness. RESULTS: The majority (70.38%) of the caregivers were male. On a scale of 0 to 15, with 0 being low and 15 being high, the average self-stigmatizing attitude score was 4.68 (±4.11). A statistically significant difference in mean self-stigma score was found between urban and rural respondents (t=3.95, P<0.05). Self-stigma of caregivers showed significant positive correlation with perceived signs of mental illness (r=0.18, P<0.001), perceived supernatural explanations of mental illness (r=0.26, P<0.001), and perceived psychosocial and biological explanations of mental illness (r=0.12, P<0.01). The only independent predictor of caregivers' self-stigma was perceived supernatural explanation of mental illness (standardized ß=0.22, P<0.001). CONCLUSION: The tendency of caregivers to avoid being identified with the patients was observed. Low exposure to mental health information was also reported. Caregivers' self-stigma in this study was significantly correlated with perceived supernatural explanation of mental illness. Since caregivers' self-stigma may negatively influence patients' treatment-seeking, adherence, and rehabilitation processes, programs that enhance coping strategies by strengthening self-esteem and empowerment by health care providers and establish family support groups may be helpful to tackle self-stigma among caregivers of people with mental illness.
