The current study examined the degree to which selected psychological characteristics (e.g., inter-personal competence, locus of control, ineffectiveness) covaried with dysfunctional eating behaviour and attitudes (i.e., drive for thinness, bulimic symptoms, body dissatisfaction). A secondary purpose was to compare the efficacy of different measures of ineffectiveness in predicting dysfunctional eating behaviour. The sample consisted of 200 female university students (ages 18-26) with no history of clinical eating disorders. Measures included the Eating Disorder Inventory (EDI: Garner et al., 1983), Bulimia Test, (BULIT: Smith & Thelen, 1984), Interpersonal Competence Questionnaire (ICQ: Buhrmester et al., 1988) and I-E Scale (Reid & Ware, 1974). Hierarchical regression analyses showed that after controlling for extraneous variables (e.g., weight stability), Interoceptive Awareness was a significant predictor of Drive for Thinness scores, Ineffectiveness was the only significant predictor of BULIT scores and both Ineffectiveness and Interpersonal Competence were found to significantly predict Body Dissatisfaction scores. With regard to the second purpose, Ineffectiveness, I-E scores and Interpersonal Competence scores were all significantly intercorrelated and Ineffectiveness was found to be a more powerful predictor than I-E scores or Interpersonal Competence scores with respect to all indices of eating disordered behaviour and attitudes.Dept. of Psychology.
