Objectives: This paper outlines a strategy for systematically examining the
discontinuity in pathways to serious dieting. Method: Eight hundred and tw
enty-three adolescent females were recruited from six high schools in metro
politan Sydney, Australia. They completed a battery of measures that assess
ed perceived social influences to diet, predisposition to conformity, prote
ctive skills, aspects of positive familial context, and dieting-related att
itudes and status. Testing took place over two occasions approximately 10 m
onths apart. Results: Family context, protective skills, and a predispositi
on to conformity were found to differentiate the vulnerable girls who repor
ted high levels of social influence from those who did not. However, those
variables did not differentiate those with high social influence who seriou
sly diet from nondieters. Body mass index, drive for thinness, and body dis
satisfaction differentiated all of the comparison groups tested. Age did no
t consistently differentiate these groups. Discussion: The findings can tel
l us what seems to protect girls who appear susceptible to social influence
s from becoming serious dieters. (C) 2000 by John Wiley & Sons, Inc.
