Community integration and related factors among people with mental illness in Japan: Multiple regression analysis stratified by social isolation level

The adaptation of the community integration scale for adults with psychiatric disorders into Chinese: Cross-cultural adaptation, reliability and validity

Community integration problems are fundamental to psychosis and are part of the diagnostic criteria for schizophrenia, but there is a lack of relevant researches and validated scales available for use in China. We intend to translate and assess the reliability and validity of the Community Integration Scale for Adults with Psychiatric Disorders (CIS-APP) scale. A cross-sectional study was conducted on a sample of 612 schizophrenic patients in China. The CIS-APP was used to collect data, and the raw data were randomly divided into two parts for an exploratory factor analysis and a confirmatory factor analysis, to evaluate construct validity. Content validity and reliability were tested by content validity index and Cronbach's α coefficients、split-half reliability respectively. A six-factor structure was emerged, and it explained 61.762% of the total variance. The fit of the six-factor model was acceptable, and the standardized factor loadings ranged from 0.412 to 0.903. The computed reliability of the scale was 0.915. The CIS-APP has excellent psychometric properties, and can be applied to measure community integration levels in people with schizophrenia.
