Primary variables diagnostic status self-rated symptoms.The process instrumental ICBT-E, contributing improvements program content being adapted needs preferences end-users. The overall found be good. ICBT-E targets key maintaining factors introducing healthy patterns addressing over-evaluation weight shape. results indicate that delivered setting, is feasible promising BED, level acceptability observed completion 73.2 %.
