Our purpose is making the objective assessment tool of social skills of persons with schizophrenia, analyzing those structure, and developing treatment for improving those. For the purpose, we modified the structured role play test to be able to assess receiving, processing, and sending skills. We chose 6 social interactions for the role play test, and these situations were found familiar and important by both 55 professionals and 32 psychiatric patients. The following are the results of field trail of the modified role play test with 36 patients with schizophrenia (ICD-10). Feasibility, reliability and validity of the test were verified.1. Feasibility : the role play test could be done within about 1 hour, and no subject showed symptom exacerbation.2. Inter-rater reliability : ANOVA-ICC of 13 rating items of the role play test among 4 raters were calculated. The ranges of the score of ANOVA-ICC were above 0.5.3. Validity: Four factors were found in factor analysis (principal component method) - total problem solving skills, self efficacy and anxiety, reception of social situation, and modification of alternatives. The score of total problem solving skills was significantly correlated with the Interpersonal relations subtest of the Life Assessment Scale for the Mentally 111 (LASMI). The GAS score was not correlated with the role play test.4. Factors contributed to social skills : The score of total problem solving skills were significantly correlated with negative symptoms, disorganized symptoms, digit span test, trail making test A and B, word fluency test, and thinking creativeness test. The score were significantly contributed by disorganized symptoms.
