Using interactive voice response technology and timeline follow-back methodology in studying binge eating and drinking behavior: different answers to different forms of the same question?

As part of a study of the relationship of binge eating, alcohol use, mood, and stressors, we compared the results of two forms of reporting on binge eating and drinking behavior. Forty-three first-year college women participated in an interactive voice response (IVR) study for 12 weeks. Participants answered computer-administered questions daily via IVR technology on number of eating binges and number of alcoholic drinks consumed. After 12 weeks, participants completed a Timeline Follow-back (TLFB) interview retrospectively for number of binges and drinks in the past 12 weeks. Results of this distally retrospective methodology (commonly used in drinking research and applied here also to binge eating) were compared to the results of daily IVR reporting. There was convergence across measures for drinking behavior, but divergence between IVR and TLFB for binge eating reports. TLFB reports underrepresented actual binge eating frequency, which calls into question the validity of applying this methodology to the assessment of binge eating.

Perfectionism, perceived weight status, and self-esteem interact to predict bulimic symptoms: a model of bulimic symptom development.

An interactive model of perfectionism, perceived weight status, and self-esteem was tested on 342 female undergraduates to predict bulimic symptoms. Using a longitudinal design, the authors tested the model on data collected at 2 points: the spring of participants' senior year of high school and during participants' first year of college. The authors hypothesized and found that self-esteem moderates the interaction between perfectionism and perceived weight status in predicting bulimic symptoms. Women who are high in perfectionism and who consider themselves overweight exhibit bulimic symptoms only if they have low self-esteem (i.e., if they doubt they can attain their high body standards). High self-esteem women with the same diathesis-stress conditions are less likely to exhibit bulimic symptoms. These findings clarify the role of perfectionism in bulimic symptomatology.

Adult physical health outcomes of adolescent girls with conduct disorder, depression, and anxiety.

OBJECTIVE: To examine the young adult physical health outcomes of adolescent girls with behavior problems. METHOD: Girls with conduct disorder, girls with depression, girls with anxiety, and healthy girls (N = 459) who had been evaluated at age 15 years were followed up at age 21, when general physical health, substance dependence, and reproductive health were assessed. RESULTS: After control for potentially confounding variables including prior health, adolescent conduct disorder predicted more medical problems, poorer self-reported overall health, lower body mass index, alcohol and/or marijuana dependence, tobacco dependence, daily smoking, more lifetime sexual partners, sexually transmitted disease, and early pregnancy. Adolescent depression predicted only adult tobacco dependence and more medical problems; adolescent anxiety predicted more medical problems. CONCLUSIONS: The robust link between female adolescent conduct disorder and poor physical health in adulthood suggests that intervention with girls who have conduct disorder may be a strategy for preventing subsequent health problems.
