神经质对青少年情绪化饮食的影响:一个有调节的中介效应模型

Adolescents:The Role of Experiential Avoidance and Self-Esteem

为探讨神经质、青少年情绪化饮食、体验回避及自尊之间的关系,选取900名青少年为被试,采用简式大五人格问卷、荷兰饮食行为问卷、接纳行动量表及自尊量表进行测试。结果表明:(1)神经质对青少年情绪化饮食有显著的正向影响,并间接地通过体验回避对青少年情绪化饮食产生作用;(2)自尊在体验回避对青少年情绪化饮食的影响中起显著的调节作用,即低自尊水平下,体验回避能显著地正向预测青少年情绪化饮食,而在高自尊水平下,体验回避对青少年情绪化饮食的预测作用不显著。

In recent decades,emotional eating has become an important issue in the study of eating disorders and obesity.Studies have shown that adolescents are also a high-incidence group for emotional eating behavior.This not only leads to adolescents’risk of obesity,but also increases their risk of eating disorders,which seriously affects the physical and mental health of young people.Therefore,the researchers believe that it is necessary to discuss the intrinsic mechanism of adolescents’emotional eating behavior,so as to provide theoretical support for the prevention and intervention strategies of adolescents emotional eating behavior,and to reduce the incidence of dietary diseases caused by emotional eating behavior.Some 900 students in middle and high schools were selected as samples,of which 288 were male and 458 were female,with an average age of 15.56 years.All the subjects assembled in class and completed the questionnaire within 20 minutes.The questionnaires included the NEO.PIR,Dutch Eating Behavior Questionnaire(DEBQ),Acceptance Action Questionnaire(AAQ),and The Rosenberg Self-Esteem Scale(RSES).Data were collected and analyzed with SPSS 24.0,Amos 21.0 and Mplus 7.4,and the bias-corrected percentile bootstrap method was used to analyze the role of experiential avoidance and self-esteem between neuroticism and adolescents emotional eating.An exploratory factor analysis was calculated to test the common method variance.Results showed that the study was in-existent common method variance.The results showed that:(1)the relationship between each pair of neuroticism,experience avoidance,emotional eating behavior,and selfesteem was significant and positive.The correlation coefficient ranged from.30 to.36(p<.01).(2)The structural equation model revealed that the data fit the theoretical model well(χ2/df=4.16,CFI=.93,TLI=.91,SRMR=.04,RMSEA=.07).(3)Neuroticism had a significant direct effect on emotional eating behavior(β=.28,p<.01);Neuroticism had a significant direct impact on experience avoidance(β=.36,p<.01);Experience avoidance had a significant direct effect of emotional eating behavior(β=.25,p<.01);Self-esteem had no significant direct effect on emotional eating behavior(β=.03,p>.05);Interaction had a significant direct effect on emotional eating behavior(β=.35,p<.01).(4)The indirect effect of neuroticism on emotional eating behavior was caused by experience avoidance,95%confidence interval was[.01,.28];(5)Self-esteem moderated the relationship between experience avoidance and emotional eating behavior.At low levels of self-esteem,there was a significant positive relationship between experience avoidance and emotional eating behavior.However,at high levels of self-esteem,there was a non-significant relationship between experience avoidance and emotional eating behavior.It is concluded that in the structural equation model of neuroticism on emotional eating behavior of adolescents,experiential avoidance plays a partial mediating role and self-esteem moderates the indirect effect.These findings suggest some measures of prevention and treatment for adolescents’emotional eating behavior should be taken.Moreover,schools and families should set up a good core self-evaluation system in order to help them improve their self-esteem and reduce experience avoidance level and eradicate emotional eating behavior.
