非适应性完美主义对青少年自伤行为的影响:一个有调节的链式中介模型

Effect of maladaptive perfectionism on adolescent non-suicidal self-injury:a moderated serial mediation model

目的 探讨非适应性完美主义对自伤行为的影响,并分析认知融合和睡眠质量的中介作用和家庭功能的调节作用。方法 采用中文Frost多维度完美主义问卷、青少年非自杀性自伤行为评定问卷、认知融合问卷、匹兹堡睡眠质量指数量表、家庭功能评定量表总体功能分量表对843名中学生进行调查。结果 非适应性完美主义、认知融合、睡眠质量、自伤行为和家庭功能,两两之间呈显著正相关。非适应性完美主义可以通过认知融合、睡眠质量的中介作用和认知融合—睡眠质量的链式中介作用对自伤行为产生间接影响。家庭功能调节模型中的两条路径,相对于家庭功能不良的个体,家庭功能良好个体的非适应性完美主义对自伤行为的直接作用更弱,其睡眠质量对自伤行为的影响较小。结论 研究结果揭示了非适应性完美主义对青少年自伤行为的影响机制,以及心理灵活性、睡眠质量、家庭功能的保护性作用,对预防和干预青少年自伤行为具有一定的启示意义。

Objective To explore the influence of maladaptive perfectionism on non-suicidal self-injury,and analyze the mediating effect of cognitive fusion and sleep quality,and the moderating effect of family function.Methods A total of 843 middle school students were surveyed by using the Chinese version of Frost multidimensional perfectionism scale(FMPS),the adolescent non-suicidal self-injury assessment questionnaire,the cognitive fusion questionnaire(CFQ),the Pittsburgh sleep quality index(PSQI),and general functioning scale of the family assessment device(FAD).Results Maladaptive perfectionism,cognitive fusion,sleep quality,self-injury behavior,and family function were significantly positively intercorrelated.Maladaptive perfectionism indirectly affected self-injury behavior through the mediating effects of cognitive fusion and sleep quality,and the serial mediating effect of cognitive fusion and sleep quality.Two paths of the model were moderated by family function.Specifically,the direct effect of maladaptive perfectionism on non-suicidal self-injury and the influence of sleep quality on non-suicidal self-injury in individuals with good family function were weaker than those in individuals with poor family function.Conclusion The results reveal the influential mechanism of maladaptive perfectionism on adolescent non-suicidal self-injury and the protective effects of psychological flexibility,sleep quality,and family function,which provides enlightenment for preventing and intervening non-suicidal self-injury of adolescents.
