“…Because these studies were conducted with randomly selected people, they find that, on average, the mean estimated food intake is 20% below the mean observed food intake and that it is below the mean observed intake in 67 of the 77 groups. It can also explain the few cases in which the mean estimation is higher than the mean observed intake; these tend to involve people with a very low BMI (e.g., anorexics), children ages 6-12 years, or parents estimating the consumption of their children ages 1-6 years (Livingstone and Black 2003; Williamson, Gleaves, and Lawson 1991). Consistent with the fourth prediction, a common characteristic of these three groups is that they consume smaller quantities than the average person, thus leading to the average overestimation bias.…”

“…The DSM-IV definitions of BN and BED require that eating episodes are considered binge eating only if they involve eating an unusually large amount of food (''objective overeating'') and a sense of loss of control over the eating episode (''loss of control''). Research has shown that study respondents do not necessarily invoke either the objective overeating or the loss of control criterion when answering affirmatively to the question of whether they have experienced episodes of binge eating (Beglin & Fairburn, 1992;Williamson, Gleaves, & Lawson, 1991). In self-report measurements, more individuals meet criteria for binge eating than in interview-based assessments (Fairburn & Beglin, 1990 because the latter permit clarification of the meaning of binge eating and rescoring of affirmative answers to negative answers if the episode was not objectively large or experienced as out of control.…”

Objective: First described over 50 years ago, binge eating disorder (BED) only recently has become the focus of epidemiologic studies. This article provides a comprehensive review of these studies. Method: Relevant studies were examined and summarized in the form of a narrative review. Results: Similar to the early studies of bulimia nervosa (BN), the first generation of epidemiologic studies of BED is limited in scope or methodology. They focus on prevalence rates and provide only basic demographic characteristics and often use less than optimal sampling or assessment methods. Discussion: Results suggest that the demographic profile of BED may be more diverse than that of BN. Future studies should evaluate complex etiologic models in representative samples that include men and a broader range of ethnic minority groups. # 2003 by Wiley Perodicals, Inc.

“…This client group has a tendency to over-estimate the frequency of binge eating episodes, often misinterpreting the consumption of a meal as a binge episode (e.g. Williamson, Gleaves, & Lawson, 1991;Wilson & Vitousek, 1999). However, other studies have contradicted these findings, suggesting a high level of accuracy in self-report by participants with BN and BED (Crowther, Lingswiler, & Stephens, 1984;Lingswiler, Crowther, & Stephens, 1989).…”

Cognitive behavioural therapy (CBT) is established as the treatment of choice for Bulimia Nervosa, but is not accessible to many sufferers living in remote and rural areas. This study used a single case interrupted time series design to examine the effectiveness of CBT delivered via videoconferencing for six participants with bulimic disorders. Weekly video‐links were conducted between the Aberdeen Eating Disorders Service and local hospitals in rural north‐east Scotland. Daily self‐monitoring diaries were used to measure reduction in bulimic symptoms. Clinically significant change was calculated on self‐report measures. At post treatment, three of six participants showed a statistically significant reduction in bingeing, and one of five in purging. Clinically significant change in bulimic symptoms was found for three as measured by the Bulimic Investigatory Test, Edinburgh. There was a clinically significant reduction for five on the Beck Depression Inventory ‐II and for four on the Borderline Syndrome Index. Results of this pilot study suggest that video therapy may lead to clinically important changes for a number of clients with bulimic disorders.
