Abstract:
Objective:To explore the effects of perceived stress on ego depletion of college students, as well as the mediating role of emotional eating and the moderating role of peer relationship.Methods:A cross-sectional survey of 1 088 college students was conducted using the perceived stress scale, the Dutch eating behavior questionnaire, the self-control resource depletion scale, and the peer relationship measurement from December 2023 to April 2024.PROCESS Macro program in SPSS 25.0 software was used to test the mediating effect of emotional eating and the moderating effect of peer relationship.Results:(1)The score of perceived stress, emotional eating, peer relationship and ego depletion were 39.26±8.35, 39.19±12.15, 2.00(1.00), and 18.19±7.15, respectively.(2)Perceived stress was positively correlated with emotional eating, ego depletion, and peer relationship( r=0.36, 0.61, 0.25, all P<0.01). Emotional eating was positively correlated with ego depletion and peer relationship( r=0.40, 0.19, both P<0.01). And ego depletion was positively correlated with peer relationship( r=0.23, P<0.01).(3)Emotional eating played a partial mediating role in the effect of perceived stress on ego depletion( β=0.077, 95% CI=0.053-0.104), and the mediating effect accounted for 12.38%(0.077/0.622) of the total effect.(4)Peer relationship played a moderating role between perceived stress and emotional eating. Under low peer relationship, perceived stress had a significant positive predictive effect on emotional eating( βsimple=0.46, P<0.01), and under high peer relationship, the predictive effect of perceived stress on emotional eating was significantly weaker( βsimple=0.26, P<0.01). Conclusions:Perceived stress not only directly affects ego depletion, but also indirectly affects ego depletion through emotional eating in college students.High levels of peer relationship can weaken the impact of perceived stress and high emotional eating on ego depletion.
