感知压力对青少年快感缺失的影响:认知重评的中介作用

Effects of perceived stress on anhedonia in teenager:Mediating role of cognitive reappraisal

目的:探索青少年群体的压力感知程度对快感缺失的影响,以及认知重评在两者之间的中介作用。方法:采用问卷调查法,对6999名中学生进行施测,测量工具包括压力感知量表、时间性快感体验量表和认知重评量表。结果:中学生感知压力与快感缺失(r=-0.192)、认知重评(r=-0.310)均呈负相关(P<0.01),认知重评与快感缺失呈正相关(r=0.376,P<0.01)。认知重评在感知压力和快感缺失之间起到中介作用(β=-0.084,P<0.01),直接效应和中介效应分别为43.50%和56.50%。结论:感知压力不仅可以直接影响中学生的快感缺失水平,还通过认知重评间接影响快感缺失。

Objective:To explore the influence of perceived stress on anhedonia in teenagers and the mediating effect of cognitive reappraisal between perceived strees and anhedonia.Methods:A total of 6999 middle school students were surveyed with questionnaires consisting of Perceived Stress Scale,Temporal Experience of Pleasure Scale(TEPS)and Cognitive Reappraisal Scale.Results:Perceived stress was negatively correlated with anhedonia(r=-0.192)and cognitive reappraisal(r=-0.310)(P<0.01),whereas cognitive reappraisal was positively correlated with anhedonia in middle school students(r=0.376,P<0.01).Cognitive reappraisal mediated the relationship between perceived stress and pleasure deficit(β=-0.084,P<0.01),and direct and mediated effects were 43.50%and 56.50%respectively.Conclusion:Perceived stress can directly affect the anhedonia of middle school students,and indirectly produce influences through cognitive reappraisal as well.
