The purpose of this study was to examine the potential moderating effect of posttraumatic stress disorder (PTSD) on the emotion-behavior relationship in individuals with bulimia nervosa (BN). A total of 119 women with BN were involved in the study. Participants were divided into two groups: those with BN and PTSD (n = 20), and those with BN only (n = 99). Ecological momentary assessment (EMA) procedures were utilized for the examination of affect, frequency of bulimic behaviors, and the relationship of affect and bulimic behavior over time. The Structured Clinical Interview for DSM-IV Axis I Disorders was conducted for the diagnosis of BN, PTSD, mood disorders, anxiety disorders, and substance use disorders. Mood disorders, anxiety disorders, and substance use disorders functioned as covariates in all analyses. Statistical models showed that those in the PTSD group reported a greater daily mean level of negative affect and a greater daily frequency of bulimic behaviors than those in the BN only group. Moderation was found for the association between negative affect and time in that the PTSD group showed a faster acceleration in negative affect prior to purging and faster deceleration in negative affect following purging. The association between positive affect and time was also moderated by group, indicating that the PTSD group had a faster acceleration in positive affect after purging than the BN only group. These findings highlight the importance of recognizing PTSD when interpreting the emotion-behavior relationship in individuals with BN.
