Associations of psychological resilience with family cohesion and non-suicidal self-injury of middle school students in Fujian Province

Objective To explore the relationship between family cohesion, psychological resilience and non-suicidal self-injury among middle school students. Methods By using the stratified random cluster sampling method, 2 065 students from 4 middle school from Fujian province were investigated with family cohesion scale, adolescent psychological resilience scale and adolescent self-injury behavior questionnaire. Results The report rate of self-injury was 40.34%, which differed by childhood migration experiences, parenting style as well as academic pressure ( χ 2 = 11.66, 29.45, 12.48, P <0.01). Total scores and dimensional scales in family cohesion and psychological resilience showed significant differences in students with or without self-injury ( t = - 8. 33, -12.08, -7.29, -11.53, -3.38, -7.37, -7.68, P <0.01) . The family cohesion was positively correlated with the psychological resilience and each dimension ( r = 0.27-0.56, P <0.01), but negatively correlated with non-suicidal self-injury ( r = -0.18, P <0.01). The psychological resilience and each dimension were negatively correlated with non-suicidal self-injury ( r = - 0. 24-- 0. 14, P < 0.01). Psychological resilience had a partial mediating effect between family cohesion and non-suicidal self-injury, with mediating effect accounting for 61.11% of the total effect. Conclusion Psychological resilience played a mediating role between family cohesion and non-suicidal self-injury. By promoting family cohesion to improve psychological resilience, it is helpful to prevent non-sui- cidal self-injury among middle school students. 【摘要】 目的 探究中学生家庭亲密度、心理弹性与自伤行为之间的关系及内在机制，为中学生自伤行为预防和干预提 供科学依据。 方法 采用分层整群抽样的方法，选取福建省4所中学的2 065名学生，采用家庭亲密度量表、青少年心理 弹性量表和青少年自我伤害行为问卷进行测量。 结果 中学生自伤行为报告率为40.34%，是否有留守经历、不同家庭教 养方式、不同学习压力学生自伤行为报告率差异均有统计学意义(χ 2 值分别为11.66,29.45，12.48，P值均<0.01)。在家庭 亲密度得分、心理弹性总分及5个维度得分上，有无自伤行为学生差异均有统计学意义（ t 值分别为-8.33，-12.08，-7.29, -11.53，-3.38，-7.37，-7.68，P值均<0.01 )。家庭亲密度总分和心理弹性总分及各维度得分均呈正相关 （r = 0.27 ~ 0.56,P 值均<0.01)，与自伤行为呈负相关 (r = -0.18，P<0.01);心理弹性总分及各维度与自伤行为均呈负相关 （r =-0.24~-0.14，P 值均<0.01)。心理弹性在家庭亲密度和自伤行为间起部分中介作用，中介效应占总效应的61.11%。 结论 心理弹性在家 庭亲密度和自伤行为间起中介作用，可通过促进家庭亲密度、提升心理弹性，预防中学生自伤行为。
