| Sumario: | Yeon-Jeong Shin,1,2 Yo-Han Joo,1 Jong-Hoon Kim1–3 1Neuroscience Research Institute, 2Department of Health Sciences and Technology, Gachon Advanced Institute for Health Sciences & Technology, 3Department of Psychiatry, Gil Medical Center, Gachon University School of Medicine, Gachon University, Incheon, Republic of Korea 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.
