A substantial body of evidence indicates that neurological, psychological, and behavioral health issues are profoundly linked to interoceptive sensitivity. The present study aimed to identify the effects of interoceptive sensitivity on the relationship between physical activity and symptoms of depression in Chinese college students. This study employed a cross-sectional design using convenience sampling. An online self-reported survey was distributed to college students in China. The participants’ interoceptive sensitivity, physical activity levels, and depressive symptoms were measured using the MAIA-2, IPAQ-SF, and PHQ-9, respectively. The mediating effect was tested via regression analysis and a parallel mediation model, with bootstrap confidence intervals for indirect effects. The results showed a significant negative correlation between physical activity and depression. A significant positive correlation was observed between physical activity and seven dimensions of interoceptive sensitivity. Conversely, interoceptive sensitivity exhibited a negative correlation with depression. The bootstrap mediation analysis showed that the “not distracting” and “trusting” dimensions of interoceptive sensitivity had significant indirect effects on the relationship between physical activity and depression, suggesting that physical activity might reduce depressive symptoms via these two interoceptive sensitivity dimensions. The findings suggest that interoceptive sensitivity should be integrated into therapeutic interventions, such as physical activity interventions, in the treatment of mental illnesses, particularly depression. Increasing physical activity levels, with a specific focus on enhancing interoceptive modulation, appears to be a promising approach for addressing depression in college students.

Background: Nurses are required to manage their emotional expressions to meet professional standards and provide optimal support. Emotional labor has become an inevitable part of their daily professional lives. Understanding the relationships between emotional labor and its antecedents is crucial for guiding nurses to adopt beneficial emotional labor strategies, thereby enhancing their well‐being and the quality of care. Aim: To examine the interdependence among emotional labor strategies, emotional display rules, emotional intelligence, and perceived organizational support among clinical nurses using network analysis, and to identify central and bridge components that may inform future nursing management research. Methods: A secondary analysis was conducted using cross‐sectional data from 2996 nurses across eight cities in Shandong Province, China. Data on emotional labor, emotional display rules, emotional intelligence, and perceived organizational support were collected. We estimated an undirected network using a Gaussian graphical model (GGM) and employed Bayesian network analysis to infer potential directional associations, visualized as a directed acyclic graph (DAG). Results: The undirected network identified “Use of emotion” and “Deep acting” as the nodes with the highest expected influence, indicating their strong connectivity with other components of the emotional labor network. “Positive display rules” exhibited the highest bridge expected influence, functioning as a link between the organizational norms and individual emotion regulation. Additionally, in the estimated DAG, “Self‐emotion appraisal” occupied a relatively upstream structural position, providing an exploratory indication of potential directional organization. Conclusions: This study provides preliminary insights into the network structure linking emotional labor, emotional display rules, emotional intelligence, and perceived organizational support among clinical nurses in Shandong Province, China. “Use of emotion,” “Self‐emotion appraisal,” and “Positive display rules” emerged as structurally important components that warrant further examination in longitudinal and intervention studies. The findings may be most applicable to clinical nurses working in similar Chinese tertiary hospital contexts. Implications for Nursing Management: In similar Chinese tertiary hospital contexts, nursing managers may consider fostering supportive work environments and developing flexible, noncoercive positive display norms that support adaptive emotional regulation and the appropriate expression of naturally felt emotions. Emotional utilization and self‐emotion appraisal may also represent relevant areas for future management programs; however, these implications are based on exploratory cross‐sectional evidence and require confirmation in longitudinal or intervention studies.
