A recent study investigated the relationship between sleep reactivity, psychological resilience, and insomnia symptoms among 1,122 young Chinese male university students, with a mean age of 21.13 years. The research explored how different dimensions of psychological resilience—Tenacity, Strength, and Optimism—might influence the association between sleep reactivity and insomnia.

The study utilized the Ford Insomnia Response to Stress Test to assess sleep reactivity, the Insomnia Severity Index (ISI) for insomnia symptoms, and the Connor-Davidson Resilience Scale to evaluate psychological resilience. Findings from the study indicated that sleep reactivity was positively correlated with insomnia symptoms. Notably, only the Strength dimension of resilience showed a significant negative association with insomnia symptoms and moderated the impact of sleep reactivity on insomnia.
Results from multiple regression analyses demonstrated that higher levels of sleep reactivity correlated with aggravated insomnia symptoms. The addition of interaction terms revealed that the influence of sleep reactivity on insomnia symptoms diminished significantly at higher levels of Strength, indicating that individuals with greater resilience might experience fewer insomnia issues in the face of stress-related sleep disturbance. This moderation effect was particularly apparent in situations involving interpersonal conflict and public speaking, suggesting that social stress is a significant factor for certain resilience dimensions.
The study highlights that Strength may serve as a crucial protective resource against the interplay of sleep reactivity and insomnia symptoms, emphasizing the importance of resilience in managing sleep-related vulnerabilities. Moreover, future research could further explore the nuances of how resilience dimensions intersect with sleep reactivity and mental health among different populations.
