Abstract:
Objective:To explore the longitudinal associations between non-restorative sleep (NRS) and non-suicidal self-injury (NSSI) among college freshmen, so as to provide a reference framework for intervention targeting adolescent NSSI behaviors.
Methods:Utilizing a combination of convenience sampling and cluster randomized sampling, a 1 year longitudinal assessment across three time points (T1, T2, and T3) was conducted from October 2023 to October 2024 among 967 college freshmen recruited from a provincial university in Guangdong. The survey was administered using the Non restorative Sleep Scale (NRSS) and the Adolescent Non suicidal Self injury Assessment Questionnaire (ANSAQ). Data analysis was performed using unconditional latent growth curve modeling (LGCM), cross lagged panel modeling (CLPM), and parallel latent growth modeling.
Results:The detection rates of NSSI behaviors in college students at T1, T2, and T3 were 18.20%, 11.89%, and 7.55%, respectively. From T1 to T3, NRSS scores showed a linear increasing trend ( β =0.67), while ANSAQ scores showed a linear downward trend ( β =-0.17) (both P < 0.05 ). Cross lagged analysis showed that NRSS scores negatively predicted ANSAQ scores (T1 NRSS scores → T2 ANSAQ scores: β =-0.10; T2 NRSS scores → T3 ANSAQ scores: β =-0.09; both P <0.01). However, in the reverse pathways, the predictive effects of ANSAQ scores on subsequent NRSS scores were not statistically significant ( β =-0.02, -0.02, both P >0.05). Parallel latent growth modeling indicated that both the initial level ( β =-0.49) and the rate of change ( β =-0.29) of NRSS scores predicted the developmental trajectory of ANSAQ scores (both P <0.05).
Conclusions:NRS is a risk factor for NSSI behaviors among college freshmen. Early assessment of and targeted interventions for NRS could potentially help mitigate the risk of NSSI occurrence.
