A cross-lagged analysis of the co-occurrence of health-risk behaviors and school connectedness among junior high school students
Objective To explore the causal relationship between adolescent school connectedness and the co-occurrence with health risk behaviors among junior high school students,so as to provide the reference for reducing the occurrence of adolescents'health risk behaviors among junior high school students.Methods A total of 924 students from two junior high schools in Jishou City were selected by the convenience sampling and cluster sampling methods,and two follow-up surveys were conducted at 6-month intervals in April(T1)and October(T2)of 2023 using the Adolescent Health Risk Behavior Questionnaire and the School Connec-tion Scale.The scores of the co-occurrence of school connectedness and health risk behaviors among junior high school students were compared by different survey periods and genders using the t-test,and cross-lagged analyses were performed using Mplus 8.3 soft-ware.Results School connectedness scores among junior high school students in T1 and T2 surveys were(38.86±7.46)(37.87±7.71)and co-occurrence of health risk behaviors scores were(1.64±0.68)(1.83±0.53),respectively,and the differences between the scores of the 2 surveys were statistically significant(t=4.24,-4.14,P＜0.05).The correlation between school connectedness and co-occurrence of health risk behaviors were statistically significant in both surveys(r=-0.46 to-0.33,P＜0.05).Cross-lagged analyses showed that school connectedness in T1 negatively predicted the co-occurrence of health risk behaviors in T2(β=-0.08),and the co-occurrence of health risk behaviors in T1 negatively predicted the school connectedness in T2(β=-0.15)(P＜0.05).Conclusions There is a longitudinal causal relationship between school connectedness and co-occurrence of health risk behaviors among junior high school students.School connectedness should be improved through various ways to reduce the co-occurrence of health risk behaviors.
