Reciprocal relationship between interpersonal communication and depressive symptoms and the mediating role of resilience across two years: Three-wave cross-lagged panel model

Psychological Capital and Its Factors as Mediators Between Interpersonal Sensitivity and Depressive Symptoms Among Chinese Undergraduates

Purpose

Current interpersonal sensitivity among college students is easily linked to mood disorders such as anxiety, depression and other mood disorders. This study aims to examine the mediating role of psychological capital and its dimensions in the relationship between interpersonal sensitivity and depressive symptoms among undergraduates.

Methods

The cross-sectional survey was conducted by using cluster stratified random sampling method across six Chinese universities between November and December 2022. The questionnaire consists of the Interpersonal Sensitivity sub-scale, the Patient Health Questionnaire, the Psychological Capital Questionnaire and the Socio-Demographic Feature Questionnaire.

Results

A total of 2580 respondents participated in the survey, with the majority being females (69.73%) and an average age of 19.22±1.28 years. Descriptive and correlation analyses were performed using SPSS v24.0, while direct and indirect effects were analyzed using PROCESS v3.4 macro. The findings revealed that interpersonal sensitivity had a significant direct effect on depression symptoms among undergraduates (β =0.416, 95% Boot CI [0.380, 0.453], p < 0.001) Additionally, psychological capital and its components were found to be negatively correlated with depression (p < 0.001). Further analysis demonstrated that hope, optimism, and resilience significantly mediated the association between interpersonal sensitivity and depressive symptoms (indirect effect: hope = 0.056, optimism = 0.074, resilience = 0.099; p < 0.001 for all).

Conclusion

These results suggest that psychological capital, including its dimensions of hope, optimism, and resilience plays a crucial role in mitigating the negative effects of interpersonal sensitivity on depressive symptoms among undergraduates.

Examining bidirectional relations between sleep problems and non-suicidal self-injury/suicidal behavior in adolescents: emotion regulation difficulties and externalizing problems as mediators

Based on previous empirical evidences and theoretical framework, sleep problems and non-suicidal self-injury (NSSI)/suicidal behavior may bidirectionally related to one another. However, this still needs to be examined through longitudinal research. Moreover, the mediating mechanisms accounting for their potential bidirectional relations have yet to be fully investigated. This study thus aimed to evaluate whether sleep problems and NSSI/suicidal behavior promoted each other directly or indirectly through the mediating roles of emotion regulation difficulties (ERD) and externalizing problems. A total of 1648 Chinese adolescents (48.12% boys; Mage = 13.69; SD = 0.82; Age range = 11-16 years old at T1) completed self-report measures on 3-time points across 1 year. Cross-lagged panel models were used to examine the focal longitudinal associations. Results revealed a predictive effect of sleep problems on NSSI and a positive bidirectional relation between sleep problems and suicidal behavior. Moreover, sleep problems exerted an indirect effect on NSSI through ERD, and vice versa. Additionally, both ERD and externalizing problems served as mediators in the pathway from suicidal behavior to sleep problems. This study disentangled the differential mediating roles of ERD and externalizing problems in the longitudinal associations between sleep problems and NSSI/suicidal behavior, which may help provide a more holistic theoretical framework through which to precisely identify key targets for early prevention and intervention of sleep problems and NSSI/suicidal behavior in adolescents.
