Positive affect and job performance in psychiatric nurses: A moderated mediation analysis

The aims of this research were (a) to determine if job satisfaction plays an intermediary role between positive affect and job performance; (b) to explore whether the mediating process of positive affect affecting job performance through job satisfaction is moderated by the work seniority of psychiatric nurses.

A questionnaire-based cross-sectional study.

From January 2021 to May 2022, a total of 328 psychiatric nurses were recruited through online advertisements. Data regarding positive affect, job satisfaction, work seniority and job performance were obtained through survey questionnaires. The moderated mediation model was examined in this study utilizing the SPSS (Version 26.0) macro process 3.3, with job satisfaction as the mediation variable and work seniority as the moderation variable.

Job performance and job satisfaction were both positively connected with positive affect, while job satisfaction was favourably correlated with job performance. Job satisfaction played a part mediating role between positive affect and job performance, with an effect value of 0.10, accounting for 22.22% of the total effect. And work seniority moderated the second half of the mediating process.

Positive affect positively affected job performance through two paths, directly or indirectly. Part of the intermediate role of job satisfaction between positive affect and job performance is regulated by seniority; that is, work seniority buffered the positive effect of positive affect on job performance.

This study revealed how positive affect works and elaborated the conditions to play a role, which greatly enriched the content of positive psychology and had important significance for deepening and expanding the relationship between positive affect and job performance. It also provided a reference for nursing managers to implement humanized management, build a high-performance psychiatric nurse team and promote the long-term development of psychiatric hospitals.

Three hundred and twenty-eight psychiatric nurses participated in the questionnaire. Trained staff were involved in data collection.
