In China, burnout is common among kindergarten, primary, and secondary school teachers. Previous studies have demonstrated that professional identity positively affects the prevention of burnout among teachers. However, studies on the mediating mechanisms behind and the moderating factors affecting this relationship remain scarce. In this study, the mediating role of work engagement as well as the moderating roles of self-efficacy and perceived organizational support in these relationships was examined. A total of 3,147 kindergarten, primary, and secondary school teachers completed self-reported questionnaires. SPSS 21.0 was used to conduct data analyses, and ordinary least square (OLS) regression was used to conduct mediation and moderation analyses. Results found that the relationship between teacher professional identity and burnout was partially mediated by work engagement. Through work engagement, teacher professional identity had the biggest predictive effects on burnout when the scores for self-efficacy and perceived organizational support were high. Implications for preventing burnout among teachers in the future were provided.

Purpose: Previous studies have investigated the relationship between alexithymia and problematic mobile phone use (PMPU). However, yet gaps in identifying the internal mechanisms of this relationship remain. Hence, based on the Interaction of Person–Affect–Cognition–Execution model, the current research examined the mediating roles of college students’ social interaction anxiousness (SIA) and boredom proneness (BPS) in the relationship between alexithymia and PMPU. Methods: A total of 1300 college students (M_age = 20.36 years, SD = 0.97) were recruited from two universities in the southeast of China to complete a series of questionnaires, including the Toronto alexithymia scale, SIA scale, BPS scale, and mobile phone addiction index questionnaire. In order to conduct conservative predictions, the demographic variables (ie, gender) were controlled as covariates. Results: The results of multiple mediation analysis showed that (1) alexithymia was positively linked with PMPU; (2) both SIA and BPS mediated the link between alexithymia and PMPU; and (3) a serial indirect pathway emerged (ie, alexithymia → SIA → BPS → PMPU). Conclusion: These findings indicated that alexithymia could influence PMPU in a simple indirect way (parallel mediation) and in a complex indirect way (serial mediation). Besides, these findings provide some insights into the prevention and intervention of PMPU.
