Abstract:
Despite decades of eating disorder (ED) research, studies of factors involved in long-term EDs are still lacking. This longitudinal study investigated the role of maintenance variables in a transdiagnostic adolescent ED sample. Participants included 275 adolescents who underwent specialized ED treatment. Hierarchical linear modeling confirmed a significant growth pattern of maintenance factors, wherein there was initial increase, then a decline during treatment, followed by a slight rebound post-treatment. Refractory status did not predict the variability in maintenance curves, suggesting that although this growth pattern existed, requiring a second treatment encounter did not explain the differences found in these patterns.
