“…In addition, the rater can assess one global score as well as subscores of the four domains: socially useful activities, personal and social relationships, self-care, and disturbing and aggressive behaviors, to be a more specific rating scale for functioning in comparison to the GAF scale and SOFAS. The reliability and validity of the PSP scale have been investigated in several studies, which have confirmed its high test-retest reliability, good inter-rater reliability validity (Morosini et al, 2000;Srisurapanont et al, 2008;Brissos et al, 2012), and high correlations with the GAF scale, SOFAS, MiniInternational Classification of Functioning-Rating for Mental Disorders (Mini-ICF-P), and Positive and Negative Syndrome Scale (PANSS) (Nasrallah et al, 2008;Apiquian et al, 2009;Patrick et al, 2009;Garcia-Portilla et al, 2011;Nafees et al, 2012;Wu et al, 2013). The PSP scale offers an efficient method of monitoring both psychosocial functioning in the acute phase and continuing treatment of schizophrenia (Kawata and Revicki, 2008;Nasrallah et al, 2008;Patrick et al, 2009), and has been translated into different languages, including German , Spanish (Apiquian et al, 2009), Portuguese (Brissos et al, 2012), Thai (Srisurapanont et al, 2008), Chinese (Tianmei et al, 2011), and Taiwanese Mandarin (Hsieh et al, 2011;Wu et al, 2013).…”
