Categories Of Cumulative Ecological Risk And Its Relations With Suicidal Ideation Among Rural Left-behind Adolescents:A Moderated Chain Intermediary Model

Cumulative ecological risk is the multiple risk factors faced by individuals in social life from family,school and peer fields.These risk factors will bring adverse development results to individual development in the form of superposition or accumulation in a bad living environment.Due to the long-term separation of parents and children,the particularity of their growth environment will lead to the accumulation or superposition of risk factors from families,schools and peers in their lives,which is more likely to cause psychological problems and even lead to suicidal ideation.In the past,researchers usually regarded cumulative ecological risk as a whole and constructed cumulative ecological risk index.Few studies systematically investigated the internal heterogeneity of cumulative ecological risk of rural left-behind adolescents,explored the longitudinal relationship between different cumulative ecological risk categories and suicidal ideation of rural left-behind adolescents,and the mechanism of self-esteem,depression and sense of control.Therefore,this study used the cumulative ecological risk indicators related questionnaire,self-esteem scale,depression scale,suicidal ideation scale and sense of control scale to conduct a one-year follow-up study on 430 students from six rural middle schools in Henan Province,Sichuan Province,Guizhou Province and Shanxi Province,and used SPSS 26.0 and Mplus 8.3 for data analysis.This study includes two sub-studies : Study 1 first used latent profile analysis(LPA)to explore the different categories of cumulative ecological risks of rural left-behind adolescents,and then used the BCH regression mixed model to compare the suicidal ideation level of rural left-behind adolescents in different cumulative ecological risk categories after 1 year;study 2 explored the chain mediating role of self-esteem and depression between cumulative ecological risk categories and suicidal ideation of rural left-behind adolescents and the moderating role of sense of control by constructing a moderated chain mediating model.The results are as follows :(1)Latent profile analysis found that the cumulative ecological risk of rural leftbehind adolescents can be divided into four subgroups with different response patterns,namely,low risk group,medium risk group,high risk group and peer risk group.(2)There were significant differences in the level of suicidal ideation among rural left-behind adolescents with different cumulative ecological risk categories after 1 year.The rural left-behind adolescents in the high-risk group,the middle-risk group and the peer risk group showed more suicidal ideation than the rural left-behind adolescents in the low-risk group;rural left-behind adolescents in the high-risk group showed more suicidal ideation than those in the middle-risk group.(3)Self-esteem plays a mediating role between cumulative ecological risk categories and suicidal ideation of rural left-behind adolescents.(4)Depression plays a mediating role between cumulative ecological risk categories and suicidal ideation of rural left-behind adolescents.(5)Self-esteem and depression play a chain mediating role between cumulative ecological risk categories and suicidal ideation of rural left-behind adolescents.(6)Compared with the low-risk group,perceived control plays a moderating role in the chain mediating effect of peer risk group and rural left-behind adolescents ’suicidal ideation.Specifically,perceived control plays a moderating role in the chain mediating effect by regulating the relationship between peer risk group and self-esteem.
