The impact of indicated prevention and early intervention on co-morbid eating disorder and depressive symptoms: a systematic review

Background: Depressive and eating disorder symptoms are highly comorbid. To date, however, little is known regarding the efficacy of existing programs in decreasing concurrent eating disorder and depressive symptoms. Methods: We conducted a systematic review of selective and indicated controlled prevention and early intervention programs that assessed both eating disorder and depressive symptoms. Results: We identified a total of 26 studies. The large majority of identified interventions (92%) were successful in decreasing eating disorder symptoms. However fewer than half (42%) were successful in decreasing both eating disorder and depressive symptoms. Intervention and participant characteristics did not predict success in decreasing depressive symptoms. Conclusions: Indicated prevention and early intervention programs targeting eating disorder symptoms are limited in their success in decreasing concurrent depressive symptoms. Further efforts to develop more efficient interventions that are successful in decreasing both eating disorder and depressive symptoms are warranted.
