INTRODUCTION: Recovery-oriented practices in mental health services have become a global priority. Despite their proven effectiveness, Japanese hospitals have not widely implemented such practices. This study clarified psychiatric nursing directors' recovery-oriented attitudes and factors regarding promoting recovery-oriented practices to identify methods for developing these practices in Japan. This cross-sectional study used a questionnaire survey with 250 nursing directors from 1287 Japanese psychiatric hospitals. Multivariable regression analysis assessed how socio-demographic variables and Recovery Knowledge Inventory (RKI) scores affected Recovery Attitudes Questionnaire (RAQ-7) scores. The analysis revealed that more clinical and managerial experience was associated with more negative recovery-oriented attitudes. High RKI scores, knowledge of strength, hospital size and outpatient work experience were associated with more positive recovery-oriented attitudes. Implementing recovery practices requires consideration of knowledge and experience in recovery and hospital size alongside recovery training based on a hospital's organizational structure. Although the low response rate could influence the study's generalisability, it could also indicate low interest in recovery-oriented practices among professionals. Acquiring more knowledge and experience regarding recovery promotes recovery-oriented attitudes among nursing directors. An appropriate organizational culture and consideration of hospital size are required when introducing such recovery practices.
