Self-Reported Graphic Personal and Social Performance Scale (SRG-PSP) for measuring functionality in patients with...

The self-reported graphic version of the Personal and Social Performance Scale (SRG-PSP) is the first graphic, self-reported rating scale that assesses functioning, and its reliability and validity have been documented in patients with schizophrenia. This study investigated the validity of SRG-PSP in patients with bipolar disorder (BD).

Patients with BD were recruited from psychiatric outpatient clinics, and assessed with the Young Mania Rating Scale (YMRS), the Montgomery-Åsberg Depression Rating Scale (MADRS), the Clinical Global Impression Scale (CGI)-Bipolar and CGI-Depression, the Positive and Negative Symptom Scale (PANSS), the Global assessment of function (GAF), and the PSP. All participants completed the self-rating questionnaires: the SRG-PSP, the 36-Item Short-Form Health Survey (SF-36), and the Sheehan disability Scale (SDS).

In total, 114 patients with BD were enrolled. The criterion-related validities between the SRG-PSP and the PSP were all significantly correlated with their counterparts. The global score of the SRG-PSP was significantly correlated with the scores of the YMRS, MADRS, PANSS, CGI-Depression, GAF, SF-36, and SDS. Three SRG-PSP domains (socially useful activities, personal and social relationships, and self-care) were negatively correlated with the scores of the MADRS, PANSS, CGI-depression, and SDS; and were positively correlated with the GAF, SF-36 scores. The disturbing and aggressive behavior domain was positively correlated with the scores of the YMRS, MADRS, PANSS, CGI-Bipolar, CGI-Depression, and SDS; and was negatively correlated with the GAF, SF-36 scores (all p<0.01).

The SRG-PSP is a validated self-reported scale for assessing functionality in patients with BD.
