Case management is a complex process involving multiple activities. It is vital that nurses are competent in all related tasks for case management. A competence scale is a valuable tool for assessing task-related competency. ⋯ There is a dearth of studies investigating the development and psychometric testing of case management competence scales. The results of this study provide evidence to support the reliability and validity of the developed case management competence scale among Taiwanese psychiatric nurses. It is a reliable and valid assessment instrument that may help identify educational needs and improve the case management competencies of nurses.
