Objective:
This study examined whether poorer friendship relations predict weight concerns and dietary restraint in adolescent girls.
Method:
Questionnaires were administered to 131 Year 9 and Year 10 girls to assess the relationship between acceptance by friends, perceived social support, friendship intimacy, and perceived impact of thinness on male (PITOF-M) and female (PITOF-F) friendships on the one hand, and body image concern, body dissatisfaction, and restrained eating on the other.
Results:
Friendship variables contributed significantly to the prediction of body image concern, body dissatisfaction, and restrained eating. The largest unique contribution to prediction was from the PITOF-M. Poor acceptance by friends significantly predicted the PITOF-M and PITOF-F. Whereas heavier girls were more likely to believe being thinner would improve their friendships, they did not experience poorer friendships.
Discussion:
Results suggest sociocultural risk factors for disordered eating and underline the importance of perceived peer affiliation on girls' body image concern and dieting.
