title: The influence of exercise identity and social physique anxiety on exercise dependence.
abstract: BACKGROUND
  Previous research has identified exercise identity and social physique anxiety as two independent factors that are associated with exercise dependence.
  
  
  OBJECTIVE
  The purpose of our study was to investigate the unique and interactive effect of these two known correlates of exercise dependence in a sample of 1,766 female runners.
  
  
  METHODS
  Regression analyses tested the main effects of exercise identity and social physique anxiety on exercise dependence. An interaction term was calculated to examine the potential moderating effect of social physique anxiety on the exercise identity and exercise dependence relationship.
  
  
  RESULTS
  Results indicate a main effect for exercise identity and social physique anxiety on exercise dependence; and the interaction of these factors explained exercise dependence scores beyond the independent effects. Thus, social physique anxiety acted as a moderator in the exercise identity and exercise dependence relationship.
  
  
  CONCLUSIONS
  Our results indicate that individuals who strongly identify themselves as an exerciser and also endorse a high degree of social physique anxiety may be at risk for developing exercise dependence.
  
  
  CONCLUSIONS
  Our study supports previous research which has examined factors that may contribute to the development of exercise dependence and also suggests a previously unknown moderating relationship for social physique anxiety on exercise dependence.
