OBJECTIVE: The construct validity and test-retest reliability of the Personal and Social Performance (PSP) scale were used to assess social functioning in a cohort of ethnically diverse UK patients with schizophrenia. METHODS: A total of 73 patients with schizophrenia took part in the study. At baseline, the PSP, two symptomatology scales and two other functioning scales were administered. A subset of the sample (N=40) took part in a retest where the Clinical Global Impression-Severity (CGI-S) and PSP scales were administered 8-10 days later. RESULTS: PSP significantly correlated with all other measures, Positive and Negative Syndrome Scale (PANSS), Global Assessment of Functioning (GAF) and Quality of Life Scale (QLS) at baseline (p<0.02) and with CGI-S at follow-up (p<0.01). In addition, the PSP scale was moderately sensitive to the severity of illness. Test-retest reliability for the PSP score was 0.45 and the scale was able to discriminate between known groups (mild and severe patients). CONCLUSION: The PSP was easy to administer in this predominantly inpatient cohort and was moderately correlated with all other functioning measures tested. Due to patient homogeneity, the test-retest reliability statistic of the PSP was lower than that observed in other studies.
