Effect of Exercise Identity on Exercise Behaviors in College Students:A Moderated Mediation Model
Objective:To explore the relationship between college students'exercise identity and exercise behaviors(adaptive and maladaptive exercise behaviors)based on the deviance regulation theory,focusing on the mediating role of in-temal motivation and the moderating role of weight bias.Methods:This study employed several assessment tools,includ-ing the Physical Activity Rating Scale,Exercise Dependence Scale,Exercise Identity Scale,Motivation for Physical Activity Measure-Revised and Weight Bias Questionnaire.A survey was conducted among 950 college students enrolled at a univer-sity in Jiangsu Province,China.After excluding 59 incomplete or invalid questionnaires,a total of 891 valid responses were included for analysis.Results:(l)Partial correlation analysis,controlling for gender and age,revealed a positive association between college students'exercise identity and both adaptive and maladaptive exercise behaviors.(2)Model fit results indi-cated that intrinsic motivation partially mediated the relationship between exercise identity and adaptive as well as maladap-tive exercise behaviors among college students.Weight bias played a moderating role in the relationship between exercise identity and intrinsic motivation concerning exercise behaviors(adaptive and maladaptive exercise behaviors).Conclusion:Exercise identity exerts a direct impact on the exercise behaviors of college students,and wields an indirect influence through intrinsic motivation.Furthermore,weight bias moderates the relationship between college students'exercise identi-ty and exercise behavior,as well as the association between intrinsic motivation and exercise behavior.
