A Retrospective Study on the Relationship Between Cognitive Function and Social Function in Patients With Schizophrenia

Abstract

Background: Social dysfunction is associated with decreased activity, employment difficulties, and poor prognosis in patients with schizophrenia. Cognitive functions, such as attention and processing speed, have been implicated in the social functions of schizophrenia patients; however, the relationship between cognitive functions and social functions remains unclear. Thus, understanding the factors that influence social functioning can aid the development of therapeutic strategies for schizophrenia. Herein, we retrospectively analyzed factors that influence social functioning in patients with schizophrenia.Methods: Patient background, intelligence quotient (IQ) scores, Japanese version of the Brief Assessment of Cognition in Schizophrenia (BACS-J) scores, the dose of antipsychotic drugs, Positive and Negative Syndrome Scale (PANSS) scores, and the factors influencing each subscale of the Japanese version of the Social Functioning Scale (SFS-J) were evaluated using univariate and multivariate analyses. The Bonferroni correction was applied to evaluate the correlation between each factor in the univariate analysis. In multivariate analysis, independent variables were selected using a stepwise method. In each model, considering the sample size, the maximum number of variables extracted using the stepwise method was set to three. We then calculated the standard partial regression coefficient (standard β) between the SFS-J subscale scores and each factor.Results: Data from 36 patients were analyzed. The average age, ill-ness duration, and total length of hospitalization were 57.8 years, 34.8 years, and 196.7 months, respectively. Of the seven significant correlations with the SFS-J subscale in the univariate analysis, only three were significant in the multivariate analysis model. According to the multivariable model, BACS-J verbal fluency positively correlated with SFS-J withdrawal, interpersonal communication, and employment/occupation. Moreover, BACS-J token motor and educational history were positively correlated with SFS-J recreation and SFS-J employment/occupation, respectively. PANSS scores, IQ scores, and doses of antipsychotic drugs did not show clear associations with SFS-J scores. Conclusions:In conclusion, there were significant correlations between BACS-J subscale scores for cognitive functioning and SFS-J subscale scores for social functioning in patients with schizophrenia.

Effect of psycho-educational program on social functioning and self-stigma among schizophrenic patients

“…Schizophrenia is a chronic psychotic condition affecting approximately 24,000,000 individuals worldwide and constitutes the majority of patients in psychiatric facilities of Egypt [13,14] . Social functioning is very impaired among schizophrenic patients and is repeatedly associated with poor adherence to medical treatment, poor prognosis, higher relapse rate, and increased risk of premature mortality [15,16] . A study conducted by Al-Maghraby et al [17] found that (78%) of the studied subjects were having poor social functioning.…”
