Cost-Effectiveness of Internet-Based Cognitive-Behavioral Treatment for Bulimia Nervosa: Results of a Randomized Controlled Trial.

Objective: To evaluate the cost-effectiveness of Internet-based cognitive-behavioral therapy for bulimia nervosa (CBT-BN) compared to face-to-face delivery of CBT-BN.

Methods: This study is a planned secondary analysis of data from a randomized clinical trial. Participants were 179 adults (98% female, mean age = 28 years) meeting DSM-IV criteria for bulimia nervosa who were randomized to group face-to-face or group Internet-based CBT-BN for 16 sessions during 20 weeks.

The core symptoms of bulimia nervosa, anxiety, and depression: A network analysis.

Bulimia nervosa (BN) is characterized by symptoms of binge eating and compensatory behavior, and overevaluation of weight and shape, which often co-occur with symptoms of anxiety and depression. However, there is little research identifying which specific BN symptoms maintain BN psychopathology and how they are associated with symptoms of depression and anxiety. Network analyses represent an emerging method in psychopathology research to examine how symptoms interact and may become self-reinforcing.

CBT4BN: A Randomized Controlled Trial of Online Chat and Face-to-Face Group Therapy for Bulimia Nervosa.

Objective: Although cognitive-behavioral therapy (CBT) represents the first-line evidence-based psychotherapy for bulimia nervosa (BN), most individuals seeking treatment do not have access to this specialized intervention. We compared an Internet-based manualized version of CBT group therapy for BN conducted via a therapeutic chat group (CBT4BN) to the same treatment conducted via a traditional face-to-face group therapy (CBTF2F).

Method: In a two-site, randomized, controlled noninferiority trial, we tested the hypothesis that CBT4BN would not be inferior to CBTF2F.

Predictors of dropout in face-to-face and internet-based cognitive-behavioral therapy for bulimia nervosa in a randomized controlled trial.

Objective: We sought to identify predictors and moderators of failure to engage (i.e., pretreatment attrition) and dropout in both Internet-based and traditional face-to-face cognitive-behavioral therapy (CBT) for bulimia nervosa.

Body image, aging, and identity in women over 50: The Gender and Body Image (GABI) study.

We conducted a qualitative study of 1,849 women over age 50 to capture the thoughts, feelings, and attitudes that women at middle age have about their bodies and the experience of aging. Via an open-ended question online survey, four primary themes emerged: (a) the physical and psychological experience of aging; (b) the injustices, inequities, and challenges of aging; (c) the importance of self-care; and (d) a plea for recognition of the need to maintain a contributory role in society. Results highlight the complexities of women's psychological and physical aspects of aging and point toward important topics worthy of further study in this growing population.

Adolescent Girls and Their Mothers Talk About Experiences of Binge and Loss of Control Eating.

Evidence suggests that adolescents' experience of binge eating (BE) might differ in important ways from that of adults. Moreover, although BE appears more common in African American women than other disordered eating behaviors, little is known about the influence of cultural factors on this behavior in adolescents. The current investigation used qualitative methodology to examine the perceptions of White and African American adolescent girls and their mothers regarding experiences of binge and loss of control eating.

Characteristics of women with body size satisfaction at midlife: results of the Gender and Body Image (GABI) Study.

This study characterizes the profile of women (N = 1,789) ages 50 and over who report body size satisfaction on a figure rating scale. Satisfied women (12.2%) had a lower body mass index and reported fewer eating disorder symptoms, dieting behaviors, and weight and appearance dissatisfaction.

Body dissatisfaction in women across the lifespan: results of the UNC-SELF and Gender and Body Image (GABI) studies.

To explore age differences in current and preferred silhouette and body dissatisfaction (current - preferred silhouette discrepancy) in women aged 25-89 years using figural stimuli [range: 1 (very small) to 9 (very large)]. Data were abstracted from two online convenience samples (N = 5868). t-tests with permutation-adjusted p-values examined linear associations between mean silhouette scores (current, preferred, discrepancy score) and age with/without stratification by body mass index (BMI).

Eating disorder symptoms and weight and shape concerns in a large web-based convenience sample of women ages 50 and above: results of the Gender and Body Image (GABI) study.

Objective: Limited research exists on eating disorder symptoms and attitudes and weight and shape concerns in women in midlife to older adulthood. We conducted an online survey to characterize these behaviors and concerns in women ages 50 and above.

Method: Participants (n = 1,849) were recruited via the Internet and convenience sampling.

CBT4BN versus CBTF2F: comparison of online versus face-to-face treatment for bulimia nervosa.

Cognitive-behavioral therapy (CBT) is currently the "gold standard" for treatment of bulimia nervosa (BN), and is effective for approximately 40-60% of individuals receiving treatment; however, the majority of individuals in need of care do not have access to CBT. New strategies for service delivery of CBT and for maximizing maintenance of treatment benefits are critical for improving our ability to treat BN. This clinical trial is comparing an Internet-based version of CBT (CBT4BN) in which group intervention is conducted via therapeutic chat group with traditional group CBT (CBTF2F) for BN conducted via face-to-face therapy group.
