title: Validation of eating and dieting expectancy measures in two adolescent samples.
abstract: OBJECTIVE
  To demonstrate the validity of two measures of eating and dieting expectancies (The Eating Expectancy Inventory [EEI] and the Thinness and Restricting Expectancy Inventory, [TREI]) for use with adolescents.
  
  
  METHODS
  Seventh (N = 392) and tenth graders (N = 300) completed the Bulimia Test-Revised (BULIT-R), the Eating Disorder Inventory (EDI-II), and two factors of the Three-Factor Eating Questionnaire (TFEQ).
  
  
  RESULTS
  Findings replicated for the two adolescent samples. The expectancy that thinness leads to overgeneralized life improvement correlated with measures of "successful" dieting, dieting plus disinhibition, and bulimic symptomatology. Expectancies for negative reinforcement from eating (e.g., eating helps manage negative affect and alleviate boredom) correlated with dieting plus disinhibition and bulimic symptoms, but not with successful dieting. Negative reinforcement from eating and reinforcement from thinness expectancies accounted for different bulimic symptom variance than that accounted for by the personality factors of perfectionism, interpersonal distrust, and ineffectiveness.
  
  
  CONCLUSIONS
  Results were consistent with prior work on college and clinical samples, thus supporting use of the expectancy measures with adolescents.
