RESUMEN
OBJECTIVE: This study investigated how the precursors of interpersonal self-efficacy and weight/shape self-efficacy would interact in the face of interpersonal stress to prospectively predict dietary restraint. Three models were explored, each with a different type of interpersonal stress: stress from same sex friendships, opposite sex friendships, or romantic relationships. METHOD: At Time 1 (T1), participants (N = 406) reported on their typical levels of interpersonal self-efficacy and weight/shape self-efficacy, and recent (past 28 days) dietary restraint. At Time 2 (T2), 11 weeks after T1, participants reported on their recent (past 28 days) levels of dietary restraint at that time. Between T1 and T2, participants completed inventories weekly on the previous week's interpersonal stressors. RESULTS: Consistent with prediction, low interpersonal self-efficacy and high weight/shape self-efficacy combined with high interpersonal stress (whether from same sex friendships, opposite sex friendships, or romantic relationships) to predict the highest levels of T2 dietary restraint after controlling for T1 levels. DISCUSSION: These results further link the interpersonal domain with dietary restraint and elucidate characteristics of women particularly apt to increase dietary restraint in response to interpersonal stress.

The current study tested a psychosocial interactive model of perfectionism, self-efficacy, and weight/shape concern within a sample of women with clinically significant bulimic symptoms, examining how different dimensions of perfectionism operated in the model. Individuals with bulimia nervosa (full diagnostic criteria or subthreshold) completed measures of bulimic symptoms, multidimensional perfectionism, self-efficacy, and weight/shape concern. Among those who were actively binge eating (n=180), weight/shape concern was associated with binge eating frequency in the context of high perfectionism (either maladaptive or adaptive) and low self-efficacy. Among those who were actively vomiting (n=169), weight/shape concern was associated with vomiting frequency only in the context of high adaptive perfectionism and low self-efficacy. These findings provide support for the value of this psychosocial interactive model among actively binge eating and purging samples and for the importance of considering different dimensions of perfectionism in research and treatment related to bulimia nervosa.

An interactive model of perfectionism, perceived weight status, and self-efficacy was tested on 406 women to predict the bulimic symptoms of binge eating and inappropriate compensatory behaviors separately. This longitudinal study assessed hypothesized vulnerabilities of high perfectionism and low self-efficacy and the stressor of feeling overweight at Time 1 and then gathered weekly assessments of binge eating, vomiting, laxative use, fasting, and diet pill use for 11 weeks. As predicted, results showed that perfectionism, weight perception, and self-efficacy interacted to prospectively predict binge eating. In particular, women high in perfectionism who felt they were overweight and who had low self-efficacy reported the most number of weeks of binge eating. This interactive model did not predict inappropriate compensatory behaviors. Future directions and clinical implications are discussed.

Flumazenil rapidly and effectively terminates the actions of benzodiazepines by competitive antagonism at specific benzodiazepine receptors in the central nervous system. This article describes the pharmacology of flumazenil and reviews the indications for its use and the adverse effects which may follow its administration.
