Background: Compassion fatigue has numerous adverse effects on the mental health of medical workers and the diagnosis, treatment of patients. The increase in role stress among medical workers is closely related to compassion fatigue. However, few studies have explored whether their relationship is mediated by emotional labor and moderated by positive psychological capital.

Methods: We investigated 1456 medical workers and assessed their role stress, compassion fatigue, emotional labor and positive psychological capital using the Role Stressors Scale, Compassion Fatigue Scale, Emotional Labor Scale and Positive Psychological Capital Questionnaire. The moderated mediation model was tested by SPSS software and PROCESS macro program.

Results: Role stress was positively associated with compassion fatigue of medical workers, and the surface acting and deep acting of emotional labor play a partial mediating role in the relationship between role stress and compassion fatigue, respectively. Positive psychological capital has a moderating effect on the second half of the path with surface acting as the mediating variable, and has a moderating effect on both the first half and second half of the path with deep acting as the mediating variable, the association of role stress and deep acting and the association of emotional labor and compassion fatigue will gradually weaken with the improvement of the level of positive psychological capital.

Conclusion: The role stress of medical workers can be associated through emotional labor and compassion fatigue, in which positive psychological capital has a certain moderating effect. High surface acting and low positive psychological capital may be important risk factors for compassion fatigue when medical workers face role stress, while high deep acting and high positive psychological capital may be protective factors for medical workers to resist compassion fatigue caused by role stress. Therefore, reducing the surface acting, improving the deep acting and enhancing the positive psychological capital of medical workers will help to alleviate their compassion fatigue and maintain their mental health.

Background: Excessive pre-sleep mobile phone use fuels bedtime procrastination and sleep insufficiency, contributing to a self-reinforcing cycle of dependency. While physical activity benefits sleep health, the reasons for sustained engagement and the role of motivation quality in downstream outcomes remain understudied. This study integrates self-determination theory, compensatory internet use theory, the self-regulatory failure model, and the dual-system model to examine how autonomous motivation operating through physical activity is associated with mobile phone addiction and bedtime procrastination.

Methods: In this cross-sectional study, 1,246 Chinese adults, including 389 university students (164 male, 225 female) and 857 working adults (524 male, 333 female), were recruited. The mean age of participants was 32.47 years (SD = 9.86). Validated scales were used to assess autonomous motivation (Behavioral Regulation in Exercise Questionnaire-3), physical activity (Physical Activity Rating Scale-3), mobile phone addiction (Mobile Phone Addiction Index), and bedtime procrastination (Bedtime Procrastination Scale). The data were analyzed using SPSS 23 and AMOS 24. Bootstrapped structural equation modeling was used to estimate the mediation effects and bias-corrected confidence intervals. Indirect effect magnitudes were quantified, and differences between standardized path coefficients (Δβ) were tested via confidence intervals and p-values. Multi-group SEM was used to evaluate model invariance across gender and occupational status.

Results: The mediation analysis confirmed two significant pathways: a behavioral pathway controlling for autonomous motivation (physical activity → mobile phone addiction → bedtime procrastination, β = -0.006, p < .001, 1.6% of the total indirect effect) and an autonomous motivation-driven chain mediation pathway (autonomous motivation → physical activity → mobile phone addiction → bedtime procrastination, β = -0.071, p < .001, 17.8% of the total indirect effect). The autonomous motivation-driven pathway exerted a markedly stronger effect than the behavioral pathway did (Δβ = -0.065, p < .001), highlighting autonomous motivation's amplifying role. Multi-group SEM confirmed full invariance across gender and occupation, supporting model robustness.

Conclusions: This study provides initial evidence that autonomous motivation is associated with sustained physical activity and indirectly associated with lower levels of mobile phone addiction and bedtime procrastination. By contrasting motivation-driven and behavioral pathways within an integrative framework, the findings underscore the relevance of motivation-focused approaches for addressing technology-related sleep problems.

Pre-service teachers' digital literacy skills are a crucial competency area that impacts both their professional development and self-efficacy. This study examines the mediating role of motivation for web-based professional development in the relationship between pre-service primary teachers' digital literacy levels and their self-efficacy beliefs. In this study, relational scanning was employed to examine relationships among variables, and a structural equation model (SEM) was used to test the mediation model. A total of 412 pre-service primary teachers from ten different universities participated in the study. Data were collected using the Digital Literacy Scale (DL), the Motivation Toward Web-Based Professional Development Scale (MWPD), and the Self-Efficacy Belief Scale (SEB). According to the research findings, there are positive and significant relationships among digital literacy, motivation for web-based professional development, and self-efficacy. As pre-service teachers' digital literacy levels increased, their self-efficacy beliefs also increased positively. An important finding of the study is that motivation toward web-based professional development mediates the relationship between digital literacy and self-efficacy beliefs. These findings highlight the role of web-based professional development in relation to pre-service teachers' self-efficacy and digital literacy in pre-service education.
