A Survey for Examining the Validity and Reliability of the Japanese Version of the Forensic Psychiatric Nursing Competence Scale

Abstract

Abstract This study aimed to authenticate the validity and reliability of the 40-item Japanese version of the Forensic Psychiatric Nursing Competence (FPNC-J) scale. We used the FPNC-J scale and conducted anonymous online surveys with 213 nurses who worked in the forensic psychiatric wards, assessed the internal consistency, test–retest reliability, and structural and convergent validities. The goodness-of-fit indices showed a poor fit. An exploratory factor analysis identified four factors. Cronbach’s a and Intraclass Correlation Coefficient indicated moderately good reliability. This suggests that the FPNC-J scale is useful for measuring competence in forensic mental health nursing practice.
