Comparing patients with complete measures at baseline and end-of-treatment (completers) with patients without complete measures (non-completers) in the TAU cohort, no differences were found with regard to demographics and psycho- pathology, although completers received more treatment sessions (p =.022). In the CBT-E cohort, completers had higher EDE-Q global, restraint and shape concern scores (respectively p = .021, p = .025 and p = .029) and a longer inpatient stay (p = .001). Comparing completers between both cohorts did not show any statistically signifi- cant differences.
Treatment outcomes for completers
Treatment outcomes for completers on eating disorder and general psychopa- thology are shown in Table 2. In both cohorts, eating disorder attitudes and general psychopathology improved over time, except for the EDE-Q subscale shape concern, which did not improve in the TAU cohort. In both cohorts, eating disorder behaviors did not improve significantly, although in the CBT-E cohort, a trend on the decrease of vomiting was found (p = .066).
Mean BMI increase in the TAU cohort was 1.3 (SD = 1.6; 95% CI 0.62, 2.01), in CBT-E 2.7 (SD = 1.9; 95% CI 2.2, 3.2); linear mixed model analyses showed that BMI increase in the CBT-E cohort was higher (EMD = 1.39, SD = .28; 95% CI 0.82, 1.9, p < .001). The DASS subscale depression decreased more in the TAU cohort (EMD = 4.22, p = .047).
