Bulimia nervosa (BN) is a complex disorder involving many interconnected symptoms.  Though Cognitive Behavioral Therapy (CBT) is the most widely recommended and effective treatment for BN, little is known about how the relationship between specific BN symptoms changes after a course of CBT.  The present study uses network analyses and network comparison tests to examine how core BN symptom networks change from baseline, at the end of 20-week CBT group treatment, and at 12-months post treatment in a sample of adults with DSM-IV diagnosis of BN (n = 196).  Using the qgraph package in R (version 3.2.4), we examined whether the structure, global strength, and edge strength of BN symptom networks changed following treatment, and whether those changes were maintained post-treatment. This approach provides unique insight into how group CBT therapy is associated with change in the behaviors and cognitions associated with BN, and which symptoms persist despite treatment.
