Objective To investigate the current status of psychiatric nurses’ knowledge, belief and practice of humanistic care andanalyze the factors influencing these domains. Methods In this cross-sectional study, 466 nurses were recruited from six psychiatric hospi-tals in Shanghai between March and May 2024 via convenience sampling. A general demographic questionnaire and a humanistic careknowledge-belief-practice scale were administered. Mediation effect testing, one-way analysis of variance, and multiple linear regression wereemployed to explore the factors affecting overall scores as well as the interrelationships among the three dimensions. Results A total of 466nurses(male: 11.80%, female: 88.20%) completed the survey. Their mean scores for the knowledge, belief, and practice dimensions, and the to-tal scale, were(77.27±14.27), (83.50±14.23), (90.86±10.96), and(84.40±11.00), respectively. Multiple linear regression analysis indicatedthat nurses’ relationships with their parents and their enthusiasm for nursing were independent predictors of the total score(P<0.05). Further-more, belief exerted a significant mediating effect between knowledge and practice, accounting for 56.74% of the total effect. Conclusion Psy-chiatric nurses demonstrate relatively limited knowledge of humanistic care, and their overall performance is primarily influenced by parentalrelationships and professional enthusiasm. Greater emphasis on familial factors and professional identity is recommended to enhance the quality of humanistic care in psychiatric nursing. |
