Effectiveness of an Aggression Management Training Program in Japan: A Quasi-Experimental Study.

This study evaluated the effects of the Comprehensive Violence Prevention and Protection Program (CVPPP) training for managing patient aggression in 95 participants who attended the FY 2019 program using a single-group pretest–posttest design. The comparison of findings before and 1 month after the training showed a significant improvement in staff anger (p < 0.01) and their negative (p < 0.01) and positive attitudes (p < 0.01) toward psychiatric inpatient aggression and confidence (p < 0.01). Staff with controlling and self-affirming traits provided more effective care and demonstrated a positive attitude toward inpatient aggression (p < 0.05).
