1. Number includes patients who have admitted to the Center for Discovery program in 2017 who needed to restore weight (N= 385). 2. Clients who had a treatment length of at least 30 days (as purging behavior was measured for a 30-day increment), who endorsed purging behavior on admission, and who had purge data for discharge were included in this analysis. One outlier was removed from the adolescent AN-P sample. Mean lengths of treatment episode were as follows: adolescent AN-P, m = 48.2 days; adolescent BN, m = 43.2 days; adult AN-P, m = 48.9 days; adult BN, m = 40.6 days. 3. Clients who had a treatment length of at least 30 days (as bingeing behavior was measured for a 30-day increment), who endorsed bingeing behavior on admission, and who had binge data present on discharge were included in this analysis. Mean lengths of treatment episode were as follows: adolescent BN, m = 42.4 days; adolescent BED, m = 40.1 days; adult BN, m = 40.9 days; adult BED, m = 45.6 days. 4. Clients who received at least 7 residential treatment days (as weight was measured once per week), who had at least one day of weight restoration, and who had %TBW data present for admission and discharge were included in this analysis. Mean lengths of treatment episode for this sample were as follows: adolescent AN, m = 45.8 days; adolescent ARFID, m = 36.3 days; adult AN, m = 39.6 days; adult ARFID, m = 39.8 days.
