Attrition rate for outpatients
Outpatient dropout rate was defined as having attended fewer than ten treatment sessions, as in the CBT-E Underweight this is when the first evaluation takes place. During TAU, attrition rate was 46.1% (18/39) versus 11.5% during CBT-E (3/26), signif- icantly lower (p = .003).
Care consumption & Admission rate
On care consumption, several differences were found. During TAU, the number of outpatient sessions was lower (M =14.5, SD = 12.09; range 4-62, median = 11) than during CBT-E (M = 31.4, SD = 15.6; range 4-57, median = 31; p < .001). During TAU period, fewer patients were admitted (33.3%) compared to CBT-E (65.9%) (p <.001). During TAU however, inpatient stay lasted longer with 64.4 nights (SD = 5.58) versus 44.3 nights (SD = 24.0) during CBT-E (p = .002).
