126 Chapter 5 Although this study constitutes of a large group at baseline and EOT, some of the FU effects may have been obscured by the smaller sample size at FU. More significant variables might have showed up at FU, had the FU-group been larger as it is. In conclusion Findings of the present study provide preliminary evidence that BED treatment outcome could be enhanced by matching individuals with certain symptom presentations to DBT-BED or CBT. Specifically, DBT-BED may be particularly effective in reducing OBE episodes in patients with high baseline levels of emotional eating (at EOT) or with high difficulties identifying feelings (at FU). Concurrently, relative to CBT+, DBT-BED may not be particularly effective in patients with low levels of emotional eating, difficulties identifying feelings, overvaluation, shape concerns and low self-esteem. The difference between treatments appears smaller for high values on these variables. However, the lack of consistent moderator findings over time along with the limitations of this study suggests that more research is needed in order to provide clinicians a solid foundation on which to base effective decisions about what works for whom. Data transparency statement We used a pooled dataset (available data) of two clinical outcome studies that were previously published: a quasi-randomized controlled trial (Lammers et al., 2020; 2021) and an effectiveness study (Lammers et al., 2022). Both studies compared group DBT-BED (Safer et al., 2009) to a more intensive outpatient CBT group-program (CBT+), based on CBT for binge eating as developed by Fairburn and colleagues (1993). The main and interaction effects researched in the present article have not been researched in any previous or current articles, or to the best of our knowledge in any papers that will be under review soon. Preliminary findings have been reported in a conference presentation (Lammers et al., 2022).
