Burgeoning research on the adolescent (e.g., middle-school) years suggests that this is a particularly vulnerable period for the development of maladaptive eating patterns. Prior research has established a link between perceptions of maternal parenting practices and adolescent onset of problematic eating behaviors. The authors hypothesized that adolescents' internalized psychological distress accounts for this relation, and they tested this hypothesis via a longitudinal, mediational study of 73 adolescent girls followed from 6th to 8th grade. Results of structural equation modeling using latent variables supported the hypothesis, identifying a time-ordered process that emphasizes the significance of the mother-adolescent relationship and the importance of targeting counseling interventions at improving parenting practices and helping adolescents to regulate negative affect as a means of preventing the development of maladaptive eating.
