Stigma resistance among people with schizophrenia at Amanuel Mental Specialized Hospital Addis Ababa, Ethiopia: a cross-sectional institution based study

Prevalence of internalized stigma in patients with psychiatric illness in Abha, Southern Region, Saudi Arabia

BACKGROUND

Mental stigma occurs when patients with various mental disorders are labeled by their disorders. Little is known about the burden of mental stigma on patients with mental disorders. The aim of this study was to evaluate the incidence of mental stigma on patients with psychiatric disorder in Saudi Arabia.

MATERIALS AND METHODS

This cross-sectional study was conducted among previously diagnosed patients with any psychiatric disorder attending King Khalid Hospital, Abha, Saudi Arabia. The patients were interviewed with a sociodemographic questionnaire and a validated Arabic version of the Internalized Stigma of Mental Illness (ISMI-29) scale. Chi-square test and t-test were used to assess the association between various demographic characteristics and presence of stigma.

RESULTS

The study included 489 patients with different psychiatric disorders. The mean age of the participants was 32.8 years and 54.6% were females. About 39% participants showed no to minimal internalized stigma, 37.4% of total sample had mild stigma, 20% had moderate stigma, and 3.7% had severe stigma. A signficantly higher proportion (71.4%) of widowed patients had stigma (P = 0.032).

CONCLUSION

Self-stigma is prevalent among patients with psychiatric disorders in Abha, Saudi Arabia, but lower than the prevalence in developing countries. Marital status has a significant impact on the prevalence and severity of the self-stigma of patients. There is a need for awareness program to reduce self-stigma. Psychiatric institutions should also focus on promotion of patients' social life and increase patient's awareness of certain issues that could prevent stigma.

Stigma resistance is associated with advanced stages of personal recovery in serious mental illness patients enrolled in psychiatric rehabilitation

BACKGROUND

Stigma resistance (SR) is defined as one's ability to deflect or challenge stigmatizing beliefs. SR is positively associated with patient's outcomes in serious mental illness (SMI). SR appears as a promising target for psychiatric rehabilitation as it might facilitate personal recovery.

OBJECTIVES

The objectives of the present study are: (i) to assess the frequency of SR in a multicentric non-selected psychiatric rehabilitation SMI sample; (ii) to investigate the correlates of high SR.

METHODS

A total of 693 outpatients with SMI were recruited from the French National Centers of Reference for Psychiatric Rehabilitation cohort (REHABase). Evaluation included standardized scales for clinical severity, quality of life, satisfaction with life, wellbeing, and personal recovery and a large cognitive battery. SR was measured using internalized stigma of mental illness - SR subscale.

RESULTS

Elevated SR was associated with a preserved executive functioning, a lower insight into illness and all recovery-related outcomes in the univariate analyses. In the multivariate analysis adjusted by age, gender and self-stigma, elevated SR was best predicted by the later stages of personal recovery [rebuilding; p = 0.004, OR = 2.89 (1.36-4.88); growth; p = 0.005, OR = 2.79 (1.30-4.43)). No moderating effects of age and education were found.

CONCLUSION

The present study has indicated the importance of addressing SR in patients enrolled in psychiatric rehabilitation. Recovery-oriented psychoeducation, metacognitive therapies and family interventions might improve SR and protect against insight-related depression. The effectiveness of psychiatric rehabilitation on SR and the potential mediating effects of changes in SR on treatment outcomes should be further investigated in longitudinal studies.

Mental health stigma and discrimination in Ethiopia: evidence synthesis to inform stigma reduction interventions

BACKGROUND

People with mental illnesses are at an increased risk of experiencing human rights violations, stigma and discrimination. Even though mental health stigma and discrimination are universal, there appears to be a higher burden in low- and middle-income countries. Anti-stigma interventions need to be grounded in local evidence. The aim of this paper was to synthesize evidence on mental health stigma and discrimination in Ethiopia to inform the development of anti-stigma interventions.

METHODS

This evidence synthesis was conducted as a part of formative work for the International Study of Discrimination and Stigma Outcomes (INDIGO) Partnership research program. Electronic searches were conducted using PubMed for scientific articles, and Google Search and Google Scholar were used for grey literature. Records fulfilling eligibility criteria were selected for the evidence synthesis. The findings were synthesized using a framework designed to capture features of mental health stigma to inform cultural adaptation of anti-stigma interventions.

RESULTS

A total of 37 records (2 grey literature and 35 scientific articles) were included in the evidence synthesis. Some of these records were described more than once depending on themes of the synthesis. The records were synthesized under the themes of explanatory models of stigma (3 records on labels and 4 records on symptoms and causes), perceived and experienced forms of stigma (7 records on public stigma, 6 records on structural stigma, 2 records on courtesy stigma and 4 records on self-stigma), impact of stigma on help-seeking (6 records) and interventions to reduce stigma (12 records). Only two intervention studies assessed stigma reduction- one study showed reduced discrimination due to improved access to effective mental health care, whereas the other study did not find evidence on reduction of discrimination following a community-based rehabilitation intervention in combination with facility-based care.

CONCLUSION

There is widespread stigma and discrimination in Ethiopia which has contributed to under-utilization of available mental health services in the country. This should be addressed with contextually designed and effective stigma reduction interventions that engage stakeholders (service users, service providers, community representatives and service developers and policy makers) so that the United Nations universal health coverage goal for mental health can be achieved in Ethiopia.

Self-stigma in Serious Mental Illness: A Systematic Review of Frequency, Correlates, and Consequences

Self-stigma is associated with poor clinical and functional outcomes in Serious Mental Illness (SMI). There has been no review of self-stigma frequency and correlates in different cultural and geographic areas and SMI. The objectives of the present study were: (1) to review the frequency, correlates, and consequences of self-stigma in individuals with SMI; (2) to compare self-stigma in different geographical areas and to review its potential association with cultural factors; (3) to evaluate the strengths and limitations of the current body of evidence to guide future research. A systematic electronic database search (PubMed, Web of Science, PsycINFO, Scopus, and Ovid SP Cumulative Index to Nursing and Allied Health Literature [CINAHL]) following PRISMA guidelines, was conducted on the frequency, correlates, and consequences of self-stigma in SMI. Out of 272 articles, 80 (29.4%) reported on the frequency of self-stigma (n = 25 458), 241 (88.6%) on cross-sectional correlates of self-stigma and 41 (15.0%) on the longitudinal correlates and consequences of self-stigma. On average, 31.3% of SMI patients reported high self-stigma. The highest frequency was in South-East Asia (39.7%) and the Middle East (39%). Sociodemographic and illness-related predictors yielded mixed results. Perceived and experienced stigma-including from mental health providers-predicted self-stigma, which supports the need to develop anti-stigma campaigns and recovery-oriented practices. Increased transition to psychosis and poor clinical and functional outcomes are both associated with self-stigma. Psychiatric rehabilitation and recovery-oriented early interventions could reduce self-stigma and should be better integrated into public policy.

Factors associated with internalized stigma for Indonesian individuals diagnosed with schizophrenia in a community setting

WHAT IS KNOWN ON THE SUBJECT?: Internalized stigma in people diagnosed with mental illness has several negative outcomes; however, it remains unclear in an Indonesian context. The human rights of people diagnosed with mental illness in Indonesia have been routinely violated because of the existing stigma against mental illness and deficiencies in the country's mental healthcare services. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: To the best of our knowledge, this is the first study to examine the level of internalized stigma and related factors among Indonesians diagnosed with schizophrenia. Almost one-third of the subjects had moderate-to-severe levels of internalized stigma, among which discrimination was the strongest type. Specifically, younger and unemployed people with more psychotic symptoms had higher levels of internalized stigma. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The provision of adequate pharmacological and psychosocial treatments to help people manage their psychotic symptoms is extremely important to ameliorate stigma. Vocational rehabilitation and employment support for unemployed people may potentially reduce their internalized stigma and promote recovery. ABSTRACT: Introduction The human rights of people diagnosed with mental illness in Indonesia have been routinely violated because of societal stigma associated with mental illness and deficiencies in the country's mental healthcare services. Knowledge about internalized stigma among people diagnosed with schizophrenia in lower middle-income Muslim countries is also scarce. Aim To identify the level of internalized stigma and related factors among people diagnosed with schizophrenia in Indonesia. Method A cross-sectional survey was conducted with a purposive sample of 300 people diagnosed with schizophrenia from an urban Indonesian psychiatric hospital. Results Almost one-third of the subjects had moderate-to-severe levels of internalized stigma, among which discrimination was the strongest type. Younger age, unemployment status and having psychotic symptoms significantly increased the risk of internalized stigma when analysed in a multivariable ordinal logistic regression. Discussion The present study firstly identified the high levels of internalized stigma among Indonesian individuals diagnosed with schizophrenia. Implications for practice Mental health nurses are suggested to provide early anti-stigma illness management and family psychoeducation interventions to people diagnosed with schizophrenia and their family caregivers, helping them to develop an optimistic understanding about the concept of schizophrenia and mitigating the negative consequences of public and internalized stigma.

Stigma Resistance and Its Associated Factors among Patients with Mood Disorder at St. Paul's Hospital and Millennium Medical College, Addis Ababa, Ethiopia, 2019

Background

Stigma resistance is described as the capacity to counteract or remain unaffected by the stigma of mental illness. Patients who have high stigma resistance have shown good treatment outcome, so working on this issue is crucial since little is known about the stigma resistance level among patients with mood disorders.

Objectives

To determine the magnitude and determinant factors of stigma resistance among patients with mood disorder attending at St. Paul's Hospital.

Methods

A cross-sectional study design was conducted on 238 study samples, and systematic random sampling was used to get the study participants. Internalized Stigma of Mental Illness Scale was used to measure stigma resistance. Data was entered using EpiData 3.1 and exported to the Statistical Package for Social Science 22.0 for analysis. Linear regression analysis (P < 0.05) was used to identify a significant association between the outcome and predictor variable.

Results

Out of 238 study samples, 235 patients took part with a 99% response rate. The overall percentage of stigma resistance was 49.5%. Low educational status (B = −1.465, 95% CI (-2.796, -0.134), P ≤ 0.031), disability (B = −0.064, 95% CI (-0.102, -0.026), P ≤ 0.001), nonadherence due to stigma (B = −1.365, 95% CI (-2.151, -0.580), P ≤ 0.001), duration of treatment (B = 0.091, 95% CI (0.042, 0.141), P ≤ 0.001), internalized stigma (B = −2.948, 95% CI (-3.642, -2.254), P ≤ 0.001), and self-esteem (B = 1.859, 95% CI (0.812, 2.906), P ≤ 0.001) were significantly associated with stigma resistance.

Conclusion

This study found that only half of the patients had stigma resistance. Low educational status, high self-stigma, low self-esteem, disability, and short duration of treatment were negatively associated with stigma resistance, so working on those modifiable identified factors with focal stakeholders will be crucial to promote the stigma resistance level of patients with mood disorder.

Prevalence and factors associated with higher levels of perceived stigma among people with schizophrenia Addis Ababa, Ethiopia

Background

Schizophrenia is a severe and disabling chronic mental disorder and accompanied by different levels of a perceived stigma that affects almost all age groups. This perceived stigma negatively impacts the quality of life, physical, and mental well-being of people with schizophrenia. It is also linked with a poor level of functioning, poor adherence to drugs, and increased dropout rate. However, research into perceived stigma and associated factors among people with schizophrenia in low- and middle-income countries are limited. Therefore, this study aimed to explore the perceived stigma and correlates among people with schizophrenia in Ethiopia.

Methods

An institution based cross-sectional study was conducted from May to June 2018. A structured, pre-tested, and interviewer-administered questionnaire was used to collect data. The standardized perceived devaluation and discrimination questionnaire was used to assess perceived stigma. The systematic random sampling technique was used to select study participants. Binary logistic regression analysis was used to identify factors associated with perceived stigma. An odds ratio (OR) with a 95% confidence interval (CI) was computed to assess the strength of the association.

Results

The prevalence of high perceived stigma was found to be 62.6% [95% CI 58.3, 67.4]. In the multivariate logistic regression, female sex [AOR = 2.30, 95% CI 1.42, 3.71], age of onset of schizophrenia [AOR = 1.85, 95% CI 1.19, 2.89], multiple hospitalizations [AOR = 1.7, 95% CI 1.16, 3.27], and duration of illness 1–5 years [AOR = 2, 95% CI 1.01, 3.27], 6–10 years [AOR = 2.48, 95% CI 1.29, 4.74], and ˃10 years [AOR = 2.85, 95% CI 1.40, 5.79] were factors significantly associated with higher perceived stigma.

Conclusion

In the present study, the prevalence of high perceived stigma among people with schizophrenia was found to be 62.6%. Female sex, age of onset of schizophrenia, multiple hospitalizations, and duration of illness were factors significantly associated with higher perceived stigma. Measures to enhance the awareness of the patients, their families and their social networks about perceived stigma and associated factors, by the leading government and healthcare institutions are warranted.

Stigma Resistance and Its Associated Factors among People with Bipolar Disorder at Amanuel Mental Specialized Hospital, Addis Ababa, Ethiopia

BACKGROUND

Stigma resistance is the capacity to cope and remain unaffected by mental illness stigmatization. In bipolar patients, having low stigma resistance may result in a higher internalized stigma, low self-esteem, and poor treatment outcome. In Ethiopia, the prevalence of stigma resistance among bipolar patients is not well known. Therefore, this study is aimed at assessing the prevalence of stigma resistance and its associated factors among bipolar patients at Amanuel Mental Specialized Hospital, Addis Ababa, Ethiopia.

METHOD

An institutional-based cross-sectional study was conducted from May 8^th to June 14^th, 2016, at Amanuel Mental Specialized Hospital. The study participants were selected using a systematic random sampling technique. The stigma resistance subscale of the internalized stigma of mental illness was used to measure stigma resistance. Bivariable and multivariable logistic regression was computed to identify factors associated with stigma resistance. Accordingly, variables with P values of less than 0.05 were considered as statistically significant predictors of stigma resistance with a 95% confidence interval.

RESULTS

In this study, 418 participants completed the interview with a response rate of 98.8%. The prevalence of low stigma resistance was 56.9% (95%CI = 51.9-61.6%). Being unemployed (AOR = 1.65; 95%CI = 1.35-1.87), high internalized stigma (AOR = 3.04; 95%CI = 1.83-5.05) and low self-esteem (AOR = 2.13; 95%CI = 1.72-6.76) were significantly associated with low stigma resistance. Conclusions and Recommendation. More than half of the bipolar patients attending the Amanuel Mental Specialized Hospital had low stigma resistance. Therefore, stigma reduction programs have focused on improving self-esteem and reducing internalized stigma to increase their stigma resistance. Mental health information dissemination regarding community support and reengagement of people with bipolar disorder is highly recommended.

Factors Associated With Primary Family Caregivers' Perceptions on Quality of Family-Centered Care in Mental Health Practice

PURPOSE

This study aimed to examine the quality of family-centered care perceived by primary family caregivers and its influencing factors in mental healthcare practice.

DESIGN

A cross-sectional, correlational study.

METHODS

A convenience sample of 121 mental health nurses and 164 primary family caregivers of patients with schizophrenia was recruited from acute psychiatric wards and chronic psychiatric rehabilitation wards in three psychiatric hospitals in Taiwan. Structured questionnaires for mental health nurses were designed to examine nurses' attitudes toward schizophrenia and the importance of families in nursing care. Primary family caregivers were assessed to determine their perceptions of quality of family-centered care. At least one primary family caregiver of patients was matched to a nurse who took major responsibility for the patient during the hospitalization. Data were analyzed with descriptive statistics, Pearson's product-moment correlations, independent t-test, one-way analysis of variance, and stepwise regression analyses.

RESULTS

Quality of family-centered care perceived by primary family caregivers regarding the provision of general and specific information, as compared to enabling and partnership, coordinated and comprehensive care, and respectful and supportive care, was relatively inadequate. Younger and more educated primary family caregivers, having relatives with schizophrenia in acute wards, less supportive nurses' attitudes toward schizophrenia, and the importance of family in nursing care were correlated with poor primary family caregivers' perceptions of quality of family-centered care. Nurses' supportive attitudes toward schizophrenia and chronic psychiatric rehabilitation wards where patients received care were key factors in determining better quality of family-centered care.

CONCLUSIONS

Findings provide a platform for the development of effective continuing education and training programs to equip mental health nurses with supportive attitudes toward mental illness and an integration of the family in nursing care, which will ultimately improve mental health care for families experiencing mental health problems.

CLINICAL RELEVANCE

Efforts in professional training to address stigma and encourage a family-centered approach into recovery-oriented practice for practicing mental healthcare providers, including mental health nurses, are recommended.

A scoping review of health-related stigma outcomes for high-burden diseases in low- and middle-income countries

BACKGROUND

Stigma is associated with health conditions that drive disease burden in low- and middle-income countries (LMICs), including HIV, tuberculosis, mental health problems, epilepsy, and substance use disorders. However, the literature discussing the relationship between stigma and health outcomes is largely fragmented within disease-specific siloes, thus limiting the identification of common moderators or mechanisms through which stigma potentiates adverse health outcomes as well as the development of broadly relevant stigma mitigation interventions.

METHODS

We conducted a scoping review to provide a critical overview of the breadth of research on stigma for each of the five aforementioned conditions in LMICs, including their methodological strengths and limitations.

RESULTS

Across the range of diseases and disorders studied, stigma is associated with poor health outcomes, including help- and treatment-seeking behaviors. Common methodological limitations include a lack of prospective studies, non-representative samples resulting in limited generalizability, and a dearth of data on mediators and moderators of the relationship between stigma and health outcomes.

CONCLUSIONS

Implementing effective stigma mitigation interventions at scale necessitates transdisciplinary longitudinal studies that examine how stigma potentiates the risk for adverse outcomes for high-burden health conditions in community-based samples in LMICs.

Development and validation of the cancer self-perceived discrimination scale for Chinese cancer patients

BACKGROUND

To develop a Cancer Self-Perceived Discrimination Scale (CSPDS) for Chinese cancer patients and to assess its reliability and validity.

METHOD

A total of 178 patients were recruited and the classical test theory was used to develop the CSPDS. Item analysis was adapted to improve the preliminary version of the CSPDS, then the reliability, the validity and the acceptability of the final version of CSPDS were assessed.

RESULTS

This CSPDS contained 14 items classified into 3 subscales: social withdrawal with 7 items, stigma with 4 and self-deprecation with 3. Good validity (χ²/df = 1.216, GFI = 0.935, AGFI = 0.903, I-CVIs> 0.80) and good reliability (Cronbach's alpha = 0.829, Spearman-Brown coefficient = 0.827, test-retest reliability coefficient = 0.944) were found. The completion time was 6.06 ± 1.80 min. Participants who were female and reported poor self-rated health tended to have higher CSPDS scores (P <  0.05).

CONCLUSIONS

The results indicated that this CSPDS could be used to assess the level of self-perceived discrimination and to preliminarily screen perceived discrimination among Chinese cancer patients, especially in Southwest China. It may provide a basis for scientific assessment of targeted patient education, psychological counseling, social interventions, and psychotherapy in the future.

Stigma resistance and its association with internalised stigma and psychosocial outcomes among psychiatric outpatients

Studies have suggested that stigma resistance plays an important role in the recovery from mental illness. However, there has been limited research in Asian countries that has examined the benefits of stigma resistance among the mentally ill in Asian populations. Hence, this study aimed to assess the prevalence of stigma resistance and establish the socio-demographic correlates of stigma resistance, as well as its association with internalised stigma and psychosocial outcomes among a multi-ethnic population of 280 outpatients with obsessive compulsive disorder (OCD), schizophrenia, depressive disorders and anxiety disorders in Singapore. Prevalence of stigma resistance measured using the Stigma Resistance subscale of the Internalised Stigma of Mental Illness Scale was 82.9%. ANOVA and logistic regressions were conducted and results revealed that: (i) Stigma resistance was positively associated with being separated/divorced/widowed but negatively associated with depression diagnosis; (ii) Psychosocial outcomes such as self-esteem and psychological health were positively associated with stigma resistance; and (iii) Internalised stigma was negatively associated with stigma resistance. Moving forward, treatments could emphasize on improving the self-esteem and psychological health of patients to increase their stigma resistance for counteracting effects of public and internalised stigma.

The Correlation Between Schizophrenic Patients' Level of Internalized Stigma and Their Level of Hope

AIM

The aim of this study is to determine the correlation between schizophrenic patients' level of internalized stigma and their level of hope.

MATERIAL AND METHOD

The population of the study consisted of patients who had been diagnosed with schizophrenia and also met the study inclusion criteria. The study sample selection from the population was not further divided; the study was conducted with 76 patients. The data of the study were collected using a personal information form, the Internalized Stigma of Mental Illness (ISMI) Scale, and Herth Hope Scale.

FINDINGS

The patients' mean score on the Internalized Stigma Scale was 72.78±16.05. Their score on the Hope Scale is 50.36±11.91. A significant negative correlation was found between the total mean scores of ISMI and the Herth Hope Scale (r=-0.360, p<0.01). A significant positive correlation was found between the stigma resistance subscale mean score of ISMI and the total mean score of the Herth Hope Scale (r=0.510, p<0.01).

CONCLUSION

The internalized stigma levels of schizophrenic patients were found to be high, whereas their hope levels were found to be moderate. A significant negative correlation was found between internalized stigma and hope. This study also found a significant positive correlation between the stigma resistance of patients and their hope levels.

The Effect of Internalized Stigma on the Self Esteem in Patients with Schizophrenia

AIM

This study has been conducted to determine the relationship between internalized stigma and self-esteem in patients with schizophrenia.

MATERIALS AND METHODS

This study was conducted using 60 patients with schizophrenia who were diagnosed as schizophrenic according to the DSM-IV diagnostic criteria in the psychiatric clinics of hospitals in Erzurum. The data were collected using the "Questionnaire on Internalized Stigma of Mental Illness Scale" (ISMI) that determines the socio-demographic characteristics of patients, and the "Short Form of Self-Esteem Scale" (SF-SES).

RESULTS

The mean Internalized Stigma of Mental Illness Scale score was high; the mean of the positive dimension of the self-esteem scale score was lower than negative dimension. A negative significant relationship was found (r=-.758, p<0.01) between the ISMI and SF-SES when we examined the relationship between the mean scores of self-esteem and internalized stigma levels of the patients. There is a significantly positive relationship between the mean scores of the stigma resistance and SERS-SF (r=.339, p<0.01).

CONCLUSION

The findings show that the patients' self-esteem decreases with the increasing levels of internalized stigma. In particular, the high level of accepting stereotyped judgments and the low stigma resistance can be associated with low self-esteem. Based on these results, increasing psychoeducation and counseling services for patients with schizophrenia, and increasing the public awareness of this issue are recommended. Advanced quantitative studies should be conducted to determine the factors related to fighting stigma.

Internalized stigma of mental illness and depressive and psychotic symptoms in homeless veterans over 6 months

We investigated the relationship between internalized stigma of mental illness at baseline and depressive and psychotic symptoms 3 and 6 months later, controlling for baseline symptoms. Data on homeless veterans with severe mental illness (SMI) were provided by the Northeast Program Evaluation Center (NEPEC) Special Needs-Chronic Mental Illness (SN-CMI) study (Kasprow and Rosenheck, 2008). The study used the Internalized Stigma of Mental Illness (ISMI) scale to measure internalized stigma at baseline and the Symptom Checklist-90-R (SCL-90-R) to measure depressive and psychotic symptoms at baseline and 3 and 6 month follow-ups. Higher levels of internalized stigma were associated with greater levels of depressive and psychotic symptoms 3 and 6 months later, even controlling for symptoms at baseline. Alienation and Discrimination Experience were the subscales most strongly associated with symptoms. Exploratory analyses of individual items yielded further insight into characteristics of potentially successful interventions that could be studied. Overall, our findings show that homeless veterans with SMI experiencing higher levels of internalized stigma are likely to experience more depression and psychosis over time. This quasi-experimental study replicates and extends findings of other studies and has implications for future controlled research into the potential long-term effects of anti-stigma interventions on mental health recovery.

Stigma Related Avoidance in People Living with Severe Mental Illness (SMI): Findings of an Integrative Review

The purpose of this integrative review is to synthesize primary evidence of the impact of internalized stigma on avoidance in adult community treatment patients living with SMI. A keyword database search of articles published through 2015 yielded 21 papers and a total of 4256 patients. Our analyses found that stigmatizing beliefs associated with avoidance are related to significant loss of self-esteem. Factors generally thought to reduce stigma internalized as self-stigmatizing beliefs, such as improved insight, increased self-awareness, and psycho-education to improve stigma coping skills, do not appear to improve self-esteem.

Self-perceived cognitive deficits and their relationship with internalized stigma and quality of life in patients with schizophrenia

BACKGROUND

We investigated self-perceived cognitive deficits and their relationship with internalized stigma and quality of life in patients with schizophrenia in order to shed light on the clinical correlates of subjective cognitive deficits in schizophrenia.

METHODS

Seventy outpatients with schizophrenia were evaluated. Patients' self-perceived cognitive deficits, internalized stigma, and subjective quality of life were assessed using the Scale to Investigate Cognition in Schizophrenia (SSTICS), the Internalized Stigma of Mental Illness Scale (ISMI), and the Schizophrenia Quality of Life Scale Revision 4 (SQLS-R4), respectively. Correlation and regression analyses controlling for the severity of symptoms of schizophrenia were performed, and a mediation analysis was conducted to examine the hypothesis that internalized stigma mediates the relationship between self-perceived cognitive deficits and subjective quality of life.

RESULTS

Pearson's partial correlation analysis showed significant correlations among the SSTICS, ISMI, and SQLS-R4 scores (P<0.01). Multiple regression analysis showed that the SSTICS and ISMI scores significantly predicted the SQLS-R4 score (P<0.01). Mediation analysis revealed that the strength of the association between the SSTICS and SQLS-R4 scores decreased from β=0.74 (P<0.01) to β=0.56 (P<0.01), when the ISMI score was statistically controlled. The Sobel test revealed that this difference was significant (P<0.01), indicating that internalized stigma partially mediated the relationship between self-perceived cognitive deficits and quality of life.

CONCLUSION

The present study indicates that self-perceived cognitive deficits are significantly associated with internalized stigma and quality of life. Furthermore, internalized stigma was identified as a partial mediator of the relationship between self-perceived cognitive deficits and quality of life. These findings suggest that clinicians should be aware that patients with schizophrenia experience significantly greater self-stigma when they suffer subjective cognitive deficits, and that this may further compromise their quality of life.
