Development and psychometric validation of the Task-Specific Self-Efficacy Scale for Chinese people with mental illness

The aim of this study was to validate a Task-Specific Self-Efficacy Scale for Chinese people with mental illness. The study included 79 men and 77 women with chronic mental illness. The Task-Specific Self-Efficacy Scale for People with Mental Illness (TSSES-PMI) and Change Assessment Questionnaire for People with Severe and Persistent Mental Illness were used as measures for the study. Factor analysis of the TSSES-PMI resulted in four subscales: Symptom Management Skills, Work-Related Skills, Help-Seeking Skills, and Self-Emotional-Regulation Skills. These community living skills were found to be related to the level of readiness for psychiatric rehabilitation among Chinese people with mental illness. In conclusion the results support the construct validity of the TSSES-PMI for the Chinese population and the TSSES-PMI can be a useful instrument for working with Chinese people with mental illnesses.
