This study was intended to investigate the validity of the model of how psycho-social factors influence adolescent girls' binge eating. Social pressures to be thinner influence much more those adolescent girls with low self-esteem. They are more predisposed to internalize this social pressure as their inner standard, which. will cause them to develop inflexible dieting attitudes and behaviors. Finally. strict dieting attitudes and behaviors will result in binge eating. Data obtained from 360 middle school girls fully support this model. The general goodness of fit index of this model was high (GFI 0.95; AGFI 0.93) and all causal paths were statistically significant (p < .01) in the assumed direction. The implications of these results were discussed in relation to intervention strategies for the prevention and treatment of binge eating and body dissatisfaction of young adolescent girls.
