The interaction of psychopathological states and psychosocial functioning determine the long-term course of schizophrenia and its treatment. To be able to achieve this interplay better, exact assessment of psychosocial functioning is needed besides measurement of psychopathology. Using the Personal and Social Performance (PSP) Scale, examination of the association between psychosocial functioning and psychopathology was conducted in a sample of 103 patients with chronic schizophrenia. Rating instruments were in addition Global Assessment of Functioning Scale and Social and Occupational Functioning Assessment Scale, as well as Positive and Negative Syndrome Scale (PANSS), Clinical Global Impression Scale, and Mini-ICF-APP-Rating for Mental Disorders (Mini-ICF-APP). Besides good psychometric properties for the PSP scale in this chronic sample, we found, as expected, significant associations between the two relevant outcome domains: results showed significant negative correlations between PSP and PANSS. Findings prove the close interplay between social functioning and psychopathology in the chronic course of schizophrenia.

Schizophrenia patients with (partially) preserved mentalising skills have fewer behavioural problems in the social domain than patients with poor mentalising abilities. Conceptual disorganisation mediates the prediction of social behavioural skills through mentalising skills, suggesting that disorganised patients may require special attention regarding social-cognitive skills training.

Background: Patients with schizophrenia are often markedly impaired in their social functioning, partly independent of symptom severity. Few studies have examined patients’ self-reporting of their social functioning, how a patient’s self-perspective differs from third-party ratings, and whether or not the patients’ self-rating of social functioning is influenced by their awareness of illness. Sampling and Methods: Based on the Personal and Social Performance (PSP) scale as a clinician-administered scale, a PSP self-rating scale for patients was developed. The study included 42 inpatients with schizophrenia. Instruments were the PSP scale, the PSP self-rating scale, the Clinical Global Impression-Severity Scale, and the Scale to Assess Unawareness of Mental Disorder. Results: A significant correlation was found between PSP self- and clinician’s rating for ‘socially useful activities’, whereas the other PSP subdimensions as well as the total score were not significantly correlated. For patients with high insight, a significantly positive association emerged with ‘disturbing and aggressive behaviour’, while there was no significant correlation between PSP self- and clinician’s ratings for the patients with poor insight into their disorder. Conclusions: Patients and clinicians only marginally converge on their judgments concerning the patients’ psychosocial functioning. Patients’ insight may have a moderating role on the approximation of agreement between self- and third-party ratings. Results are discussed in line with the present literature regarding the accuracy of self-awareness in schizophrenia.

In the treatment of schizophrenia, the domain of psychosocial functioning is an important aspect of therapeutic success that should be considered in addition to the reduction of psychopathology. Valid and standardised measures are necessary for diagnostics and the assessment of patients" personal, social and professional functioning. The German version of the Personal and Social Performance (PSP) Scale (with its four subdimensions: "socially useful activities, work and study included", "personal and social relationships", "self-care" and "disturbing and aggressive behaviour") was administered to patients with schizophrenia in previous studies. These data demonstrated this scale to be a reliable, valid and efficient tool for measuring psychosocial functioning in schizophrenia. Thus, it is argued that, for everyday clinical practice, the PSP Scale is useful for the assessment of psychosocial functioning in schizophrenia during short, medium and long-term treatment courses.
