Association of Taiyin personality traits with sleep quality among college students: parallel indirect effects through resilience and rumination.

AIM: To investigate the relationships and pathways among Taiyin personality trait, resilience, rumination, and sleep status in a college student population.

METHODS

Using a cluster sampling method, 500 undergraduate students from a general higher education institution were selected as participants. They were surveyed using the Five-Pattern Personality Inventory (Taiyin Personality Subscale), the Rumination Response Scale, the Chinese Revised Version of the Connor-Davidson Resilience Scale, and the Pittsburgh Sleep Quality Index (Chinese Revised Version).

RESULTS

(1) The anal revealed a significant positive correlation between Taiyin personality and the Pittsburgh Sleep Quality Index score (r = 0.405, p < 0.01), and this personality trait positively predicted sleep quality (β = 0.130, p < 0.01). Individual scores on the Taiyin personality trait showed a positive correlation with Pittsburgh Sleep Quality Index scores, indicating that higher scores on this personality trait were associated with poorer sleep quality. (2) After controlling for all demographic variables, the Bootstrap test results confirmed that resilience played a partial mediating role between the Taiyin personality trait and the Pittsburgh Sleep Quality Index score. The mediation effect size was 0.0345 (95% CI: 0.015 to 0.054), accounting for 26.46% of the total effect. Rumination also served as a partial mediator between the Taiyin personality trait and the Pittsburgh Sleep Quality Index score, with a mediation effect size of 0.0567 (95% CI: 0.036 to 0.081), contributing 43.48% of the total effect.

CONCLUSION

The Taiyin personality trait is directly correlated with the sleep status of college students and also indirectly influence sleep quality through the two pathways of resilience and rumination.
