Shorter communicationEvaluation of the DSM-5 severity indicator for binge eating disorder in a community sample

Participants
Participants were 338 community volunteers drawn from a larger series of 3283 respondents to online advertisements seeking volunteers aged 18 years or older for a research study about eating and dieting. Participants were selected from the larger sample per criteria used to define our study group of persons with BED. Advertisements with a link to a web survey were placed on Craigslist internet classified ads in various US cities in order to enhance geographic generalizability. The participant
Binge eating disorder: DSM-5 severity groups
In the overall participant group of N = 338 with BED, the following DSM-5-defined severity groups (based on frequency of binge eating episodes) were observed: 264 (78.1%) categorized as mild (defined as 1–3 episodes/week), 67 (19.8%) as moderate (4–7 episodes/week), 6 (1.8%) as severe (8–13 episodes/week), and 1 (.3%) as extreme (14 or more episodes/week). Thus, analyses compared mild versus moderate severity groups; the low frequency of severe and extreme severity groups precluded their
Discussion
This study yielded two primary findings. First, the findings provide new, albeit limited, support for the DSM-5 severity criterion for BED. In this non-clinical study group of community volunteers, nearly no participants were categorized with either severe or extreme severity of BED based on their self-reported binge-eating frequency. Participants with BED categorized with moderate severity had significantly greater eating-disorder psychopathology but not depression than participants

Bi-directional associations between depressive symptoms and eating disorder symptoms in early adolescence
2022, Body ImageCitation Excerpt :The selection of ED symptoms for inclusion was guided by criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) (American Psychiatric Association, 2013) and the selection of symptoms in prior studies; thereby providing an opportunity to present the findings of this study in the context of the wider body of literature. The DSM-5 identify shape and weight dissatisfaction and overvaluation as key criteria for Anorexia Nervosa and Bulimia Nervosa and there is growing evidence to support their role in Binge Eating Disorder (Duarte, Ferreira, & Pinto-Gouveia, 2016; Grilo, Ivezaj, & White, 2015; Yiu, Murray, Arlt, Eneva, & Chen, 2017). Additionally, shape and weight dissatisfaction and overvaluation, along with preoccupation with shape or weight, have been selected as important ED symptoms in prior studies (e.g., Askew et al., 2020; Messer, McClure, Lee, & Linardon, 2021; Sharpe et al., 2018).

2019, Psychiatric Clinics of North AmericaCitation Excerpt :Several studies have begun to explore the degree to which the DSM-5 severity ratings are related to psychopathologic measures and outcome. Some,7–11 but not all,12–15 have suggested the severity ratings have merit. Substantial additional work is needed to assess the value of these ratings in clinical management and how the ratings might be improved.
