Adolescent bulimia nervosa (BN) remains relatively understudied, and the complex interaction between core eating psychopathology and emotional regulation difficulties provides ongoing challenges for full symptom remission. In an open pilot trial, we aimed to investigate the efficacy
of a program integrating family-based treatment (FBT) and dialectical behavior therapy (DBT) in treating adolescent BN, without exclusion criteria. Participants were 35 adolescents who underwent partial hospital treatment for BN, and outcomes included measures of core BN pathology and emotional
regulation difficulties, as well as parental measures of self-efficacy, completed at intake and discharge. Results indicate significant improvements in overall eating disorder pathology, t(68) = 4.52, p = .002, and in core BN symptoms, including objective binge episodes, t(68)
= 2.01, p = .041, and self-induced vomiting, t(68) = 2.90, p = .005. Results also illustrated a significant increase in parental efficacy throughout the course of treatment, t(20) = .081, p = .001, although no global improvement in difficulties in emotion
regulation was noted, t(68) = 1.12, p = .285. These preliminary findings support the utility of this integration of FBT and DBT, although raise interesting questions as to the mechanism of symptom remission.
