医学生情绪调节策略在不良教养方式与自伤行为间的中介作用

The mediating effect of emotion regulation strategy between inappropriate parenting styles and selfinjury in medical students

目的探讨医学生父母不良教养方式、情绪调节策略与自伤水平之间的关系。方法选取广东某医科大学学生1096人，采用青少年自我伤害量表、情绪调节量表和父母教养方式量表中的不良方式维度（包括父亲冷漠拒绝、母亲冷漠拒绝、父亲过度保护和母亲过度保护）进行评估。结果医学生在父、母冷漠拒绝，父、母过度保护，认知重评，表达抑制和自伤中的得分分别是（4．3±3．3）分、（3．9±3．0）分、（5．7±3．3）分、（6．1±3．5）分、（36．1±6．7）分、（25．7±7．4）分和（1．0±2．9）分。自伤与父亲冷漠拒绝、母亲冷漠拒绝、父亲过度保护、母亲过度保护及表达抑制呈正相关（r=0．08-0．20，均P〈0．01）；与认知重评呈负向相关（r=-0．10，均P〈0．01）。认知重评在父母冷漠拒绝维度与自伤行为之间具有部分中介效应，所占比例为9．3％；表达抑制则在父母冷漠拒绝、父母过度保护与自伤行为之间具有部分中介效应，所占比例分别为14．5％，17．9％。结论情绪调节策略在父母教养方式和医学生自伤水平之间起中介作用，不同的情绪调节策略（认知重评和表达抑制）所起的作用不同。

Objective To explore the relationships between inappropriate parenting styles,emotional regulation strategies and seff-injury.Methods A total of 1 096 medical students anonymously completed adolescents self-harm scale,emotion regulation scale （ERS） and the rejection and over-protection subseales of parental bonding instrument （PBI）.Results The scores of paternal rejection, maternal rejection, paternal over-protection, maternal over-protection, cognitive reappraisal, expression suppression and self-injury were （4.3±3.3）, （ 3.9±3.0）, （ 5.7±3.3）, （ 6.1±3.5）, （ 36.1±6.7）, （25.7±7.4） and （1.0±2.9） ,respectively.The scores of self-injury were positively correlated with the scores of paternal rejection, maternal rejection, pater- nal over-protection, maternal over-protection and expression suppression （r= 0.08-0.20, P〈0.01 ） , meanwhile negatively correlated with the scores of cognitive reappraisal（ r=-0.10 ,P〈0.01 ）.Cognitive reappraisal mediated the relationship between parental rejection and self-injury, which accounted for 9.3% .Expression suppression mediated the relationship between parental rejection, parental over-protection and sell-injury, which accounted for 14.5% and 17.9% ,respectively.Conclusion The emotion regulation strategy act as a mediator between the inappropriate parental styles and self-injury in medical students.In addition, different emotion regulation strategies （cognitive reappraisal and expression suppression） play different roles in such relationship.
