| 其他摘要 | Non-suicidal self-injury (NSSI) refers to the deliberate infliction of socially unsanctioned self-injury to physical surfaces without suicidal intent, commonly through cutting, scraping and banging.Existing studies on the mental health of ethnic minorities mainly focus on college students, and few quantitative studies on non-suicidal self-injury and related factors of ethnic minority adolescents.Previous research has shown that family functioning (cohesion and adaptability), school environment (school connectedness) and individual emotional factors (depression) are all important factors influencing non-suicidal self-injury in adolescents, but there is a lack of in-depth research on the processes and mechanisms that produce their effects. In this study, a moderated mediation model was constructed based on the motivation-volitional model, experience avoidance model, circumplex model of family systems and attribution theory to explore the relationship between family intimacy and adaptability, depression, school bonding and non-suicidal self-injury among Yunnan ethnic minority adolescents.
In this study, the cross-sectional and longitudinal design was adopted, and the Family Adaptability and Cohesion Scale, the Non-Suicidal Self-Injury Behavior Questionnaire, the Center for Epidemiological Studies Depression Scale, and the School Connectedness Scale were used to follow up the minority students in Grade one and grade two at an ethnic autonomous area in Yunnan Province at an interval of three months.In study 1，demographic variables were analyzed through SPSS and PROCESS to establish a moderated mediation model for the first time collected data, and to explore the cross-sectional relationship between family intimacy and adaptability and non-suicidal self-injury among ethnic minority adolescents in Yunnan province, as well as the mediating effect of depression and the moderating effect of school bonding on the mediating effect.In Study 2, Amos data analysis was used to explore the longitudinal relationship of variables in study 1，further testing the relationship between family intimacy and adaptability of ethnic minorities in Yunnan province and non-suicidal self-injury, and whether the longitudinal mediating effect of depression on this relationship and the moderating effect of school connection were established and stable.
The results found that :Cross-sectional studies have shown that after controlling for gender and age,(1)Family intimacy and adaptability of Yunnan minority adolescents negatively predicted non-suicidal self-injury; (2) Depression mediates the relationship between family intimacy and adaptability and non-suicidal self-injury among Yunnan minority adolescents; (3) School connectedness moderates the relationship between depression and non-suicidal self-injury in Yunnan minority adolescents; Longitudinal studies have shown that after controlling for gender and age,(4) The effects of family intimacy and adaptability on the longitudinal prediction of non-suicidal self-injury among Yunnan minority adolescents were established; (5) Depression plays a longitudinal mediating role between family intimacy and adaptability of Yunnan minority adolescents and non-suicidal NSSI, and also interacts with non-suicidal NSSI.
The cross-sectional and longitudinal studies of this study suggests that good family cohesion and adaptability not only help to reduce non-suicidal self-injury among Yunnan ethnic minority adolescents, but also reduce the incidence of self-injury through lower levels of depression.In the cross-sectional study, the school connection has a significant moderating effect on depression and non-suicidal self-injury, but the longitudinal effect is not significant.This study validated the joint mechanism of family, school and individual factors on non-suicidal self-injury among ethnic minority adolescents, which provides a theoretical reference for psychological counselling for ethnic minority adolescents and has practical implications for the prevention and intervention of non-suicidal self-injury among ethnic minority adolescents. |
