App-based body scans and heart rate training aim to curb binge eating in new study

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * ages 18-64; * no changes to ED treatment in the past 4-weeks; * agree not to access other eating disorder treatments throughout the studies (unless warranted by a worsening of participants' symptoms during the study period; see Monitoring Participant Safety for more information); * no bariatric surgery (prior or planned during the study period); * no pregnancy or lactation (current or planned during the study); * own an Apple or Android-brand iOS smartphone (which is required for compatibility with the apps used in this study; * reside in the continental U.S.; * meet Diagnostic and Statistical Manual of Mental Disorders-5-TR (DSM-5-TR) criteria for binge eating disorder (BED) or bulimia nervosa (BN), both of which include objective binge eating (i.e., consuming a larger amount of food than most people would eat in a similar period of time under similar circumstances with loss of control over eating during the episode) ≥1x/week over the past 3 months (APA, 2022). Single-item questions will determine eligibility via criteria 1-7. Criterion 8 for will be determined via the Eating Disorder Diagnostic Scale for the DSM-5 (EDDS-5; Stice et al., 2000, 2004), which has exhibited good sensitivity (.88), specificity (.98), and positive predictive power (.74) for detecting EDs among community samples (Stice et al., 2000, 2004). Exclusion Criteria: * not between the ages of 18 and 64; * had changes to ED treatment in the past 4 weeks; * plan to access other eating disorder treatments throughout the study; * received or are planning to undergo bariatric surgery during the study period; * currently pregnant or lactating, or planning to become pregnant or lactate during the study period; * no Apple or Android-brand iOS smartphone; * do not live in the continental U.S.; * do not currently experience BN or BED.
