Abstract

A total of 5785 freshmen were studied over two years to examine the relationship between insomnia, resilience, and suicidality.

Insomnia symptoms and suicidality mutually predicted each other over time.
Resilience played a mediating role in the relationship between insomnia symptoms and suicidality.
The findings suggest that resilience may influence the impact of insomnia on suicidal thoughts.
The study highlights the importance of resilience-oriented interventions for university students at risk of suicide.

BACKGROUND: Insomnia has been identified as a potential risk factor for suicidality. However, to date, few studies using the longitudinal-design have examined the underlying mechanism of this relationship. Based on a resilience perspective, this study aimed to investigate the dynamic longitudinal relationships between insomnia, resilience, and suicidality.

METHODS: A total of 5785 freshmen were sampled from a large-scale health-related cohort among Chinese college students. This study spanned six waves, covering the period from 2020 to 2022. Data from Tto Twere used because resilience was not measured at baseline (T) and T. The cross-lagged panel models and the latent growth curve mediation model were used to examine the longitudinal dynamic relationships between insomnia, resilience, and suicidality. 1 4 0 5

RESULTS: The results showed that insomnia symptoms and suicidality mutually predicted each other, and resilience played a longitudinal mediating role in linking insomnia symptoms and suicidality.

CONCLUSIONS: Given that resilience served as a mediator in the relation between insomnia symptoms and suicidality, some resilience-oriented prevention and intervention programs will be helpful in reducing the risk of suicide among university students.
