Self-esteem as a catalyst for change in adolescent inpatients with anorexia nervosa: a pilot randomised controlled trial.

PURPOSE

To determine the potential effectiveness of a six-session manualised self-esteem group using CBT approaches when given as an adjuvant to adolescent inpatients with Anorexia Nervosa (AN).

METHODS

Using a randomised controlled design, 50 girls aged 12-17 years with AN were assigned to either self-esteem group with treatment as usual (TAU) (n = 25) or TAU alone (n = 25). 50/78 (64%) consented to be randomised. Both groups completed self-report measures of self-esteem and eating disorder psychopathology at three time points to measure the potential effectiveness of the treatment. Qualitative feedback was collected to assess acceptability.

RESULTS

29 participants completed the study: 15 self-esteem group with TAU, 14 TAU alone. Self-esteem group participants had greater improvement in all outcomes than TAU participants at all time points, the difference in self-report self-esteem at T2 is 1.12 (95% CI - 1.44-3.69; effect size = 0.21). Similar small effect sizes were found for the eating disorder psychopathology measure following completion of the intervention but not at four-week follow-up. Favourable qualitative feedback was gained.

CONCLUSION

These findings demonstrate that the self-esteem group supplements an intensive treatment package which also addresses elements of low self-esteem. The self-esteem group was beneficial for addressing self-esteem and acted as a catalyst for change in eating disorder psychopathology. Positive qualitative feedback indicated the intervention was acceptable to users. Self-esteem group is a potential new adjuvant treatment for AN.
