RESUMO
UNLABELLED: Among the chronic mentally ill patients, disabilities invade most parts of their social functioning, and influences their long term course profoundly. It is important clinical issue to improve disability. Social skills training is assumed to be effective method to improve disability, and it has been disseminated over Japan recently. The assessment system to evaluate disabilities objectively at the viewpoint of social skills must be required to verify effects of social skills training, and to develop further effective therapeutic method. A role play test is the assessment tool for social skills through role plays under specific social conditions. It was reported to be useful as the method of functional assessment before treatment, and as the tool to evaluate effects of treatment to improve disability. PURPOSE: We created the Role Play Test (RPT) which was adapted to Japanese cultural background, and we tried to verify feasibility, reliability, and validity of the RPT. SUBJECTS: Thirty out-patients attending in the Day Hospital attached to Tokyo University Hospital. Twenty-six were schizophrenia, and 4 were other diagnoses. METHOD: Subjects were assessed with the RPT, BPRS, SANS, four rating scales for social functioning, and self-efficacy rating scale. The RPT was designed to assess components of social skills--social perception, role play behavior, and self-efficacy. Role play behaviors were recorded with video tapes for analysis of interrater reliability. The RPT is consisted of 12 scenes to evaluate social skills which are required in daily life. Statistical analyses were done with SAS (Statistical Analysis System). RESULTS: (1) The RPT was presumed to be feasible clinically, because the RPT could be practiced easily and responsibilities of both subjects and testers were not so much. (2) Interrater reliabilities assessed with ANOVA-ICC on 12 items was sufficiently high except one item. (3) Construct validity was certified through factor analysis, and criterion-related validity was certified through correlation analysis with other rating scales of social functioning. (4) Individual profile of the RPT should be useful instrument for functional analysis before social skills training. We also discussed on some hypotheses on the causal relationship between positive and negative symptoms and social skills. The RPT could be used as a tool to research causes of disabilities, and to evaluate improvement of social functioning after psycho-social intervention including social skills training, because the RPT can assess social skills quantitatively according to the cognitive-behavioral model.
