IntroductionSelf-stigma refers to the process in which a person internalizes negative stereotypes, beliefs, and prejudices about their mental illness, adopting a stigmatized view of themselves. Severe mental illness is one of the most socially exclusive stigmata and is associated with poor clinical and functional outcomes and social withdrawal.ObjectivesIn Portugal, investigation regarding self-stigma is scarce. In this study, we aim to evaluate the impact of self-stigma among people with diagnosis of severe mental illness (SMI). For this goal we assess the prevalence of self-stigma of psychiatric patients with diagnosis SMI; and investigate the correlates of elevated self-stigma levels.MethodsFifty-one outpatients with SMI, were recruited from a community psychiatry unit from Porto, Portugal. After informed consent, evaluations included sociodemographic data, illness characteristics, and self-reported standardized scales. Self-stigma (ISMI), self-esteem (RSES) and quality of life (WHO-QoL) were assessed. Data analyses were performed using the SPSS version 28.0 (IBM Corp., Armonk, NY). p-values<0.05 were considered significant.ResultsFrom the study sample, 66.7% were male, with mean age of 44.8±11.0 and 56.9% were single. 33.3% reported living with their parents while 31.4% were living with a partner/spouse. The majority of participants had a diagnosis of schizophrenia (60.8%). Concerning the level of education, 58.8% completed basic education, but most patients were retired due to illness (62.7%). In this study, moderate to high self-stigma levels was found in 31.4% participants. Proportion of elevated self-stigma was significantly higher in unemployed/retired patients vs. those who were active (39.0% vs. 0%; P=0.021). No significant correlations were found with age, level of education, age at diagnosis, duration of illness, and number of hospitalizations. In the correlations analysis, a negative correlation between self-stigma and self-esteem (rho=-0.745; P<0.001), as well as self-stigma and quality of life (rho=-0.585; P<0.001) was found. A positive relationship between self-esteem and quality of life (rho=0.551; P<0.001) was found.ConclusionsThis study investigates, for the first time, the prevalence of self-stigma among outpatients with SMI in a community psychiatric unit from Porto. Our findings suggest a high prevalence of elevated levels of self-stigma among these patients. A significant association with being unemployed/retired was also found. Our results support previous evidence that internalized stigma is strongly associated with diminished self-esteem and impaired quality of life, in particular those aspects related to physical and psychological complaints. Targeting internalized stigma and self-esteem among patient with SMI will likely improve their quality of life, besides improving their clinical and functional outcomes.Disclosure of InterestNone Declared
