ABSTRACT
OBJECTIVE: This study presents the results of a receiver operating characteristics (ROC) analysis to evaluate response to cognitive behavioral treatment (CBT) for patients with bulimia nervosa (BN), delivered via telemedicine (TV-CBT) or face-to-face (FTF-CBT). METHOD: Data were gathered on 116 adults treated with CBT for BN. Response to treatment (i.e., percent reduction in binge eating and purging behavior) were examined at weeks two, four, six, and eight. ROC analysis was completed to predict abstinence at end of treatment (EOT) as well as 3-month and 1-year follow-up for the entire sample and by treatment group (TV-CBT versus FTF-CBT). RESULTS: ROC analyses revealed that abstinence at EOT and 1-year follow-up was predicted by percent reduction in binge eating behavior whereas abstinence at 3-month follow-up was predicted by percent reduction in purging behavior. Results showed differences in predictors of treatment response when ROC analyses were completed for the entire sample and by treatment group. DISCUSSION: Results suggest that evaluating percent reduction in binge eating and purging at weeks two, four, six, and eight of treatment is a clinically useful tool for predicting treatment response at EOT, 3-month, and 1-year follow-up.

OBJECTIVE: To identify risk factors that may contribute to the development and/or maintenance of overweight and obesity in American Indian children. METHODS: The sample consisted of 291 tribally enrolled American Indian children. Body mass index (BMI) was measured by a tribal program and children completed self-report measures during health class. Hierarchical multiple regression analyses were conducted for 232 children and included three blocks of predictor variables (diet and physical activity, weight-related attitudes, and psychosocial variables). RESULTS: Thirty-three percent of children were obese and 20% were overweight. Diet and physical activity (7.6%) and weight-related attitudes (31.9%) made significant contributions, explaining 39.5% of the variance in BMI. CONCLUSIONS: Greater BMI scores were related to healthier food choice intentions, more hours of television viewing, greater body dissatisfaction, higher negative attitudes toward body size, and more weight loss attempts.
