Abstract

Background: The Personal and Social Performance (PSP) scale is used for the assessment of patient function by mental health professionals. This study aimed to evaluate the internal reliability and validity of a self-reported graphic version of the PSP (SRG-PSP) scale and its correlations with psychiatric symptoms, daily life ability and quality of life. Methods: The SRG-PSP scale was developed following the four PSP domains: socially useful activities, personal and social relationships, self-care, and disturbing and aggressive behavior. In total, 108 patients with schizophrenia were enrolled. All participants completed the SRG-PSP, the Activities of Daily Living Rating Scale II (ADLRS-II), and the World Health Organization Quality of Life-BREF (WHOQOL). They were also assessed using the PSP and the Positive and Negative Syndrome Scale (PANSS). Spearman's ρ was used to examine the correlations between SRG-PSP scores and other variables. Results: The results of the SRG-PSP were significantly correlated to those of their corresponding criteria on the PSP. The global score of the SRG-PSP and the scores of three domains, socially useful activities, personal and social relationships, and self-care, were positively correlated with most sub items of the ADLRS-II and WHOQOL, and were negatively correlated with the PANSS scores. The disturbing and aggressive behavior domain of the SRG-PSP was negatively correlated with most sub items of the ADLRS-II and WHOQOL (ρ = - 0.19 to - 0.36, all p < 0.05) and positively correlated with the PANSS (ρ = 0.24-0.30, all p < 0.05), with the exception of negative symptoms (ρ = 0.09, p = 0.40). Conclusion: The SRG-PSP is a valid self-reported scale for the assessment of functionality in patients with schizophrenia.
