Aims: The transdiagnostic cognitive-behavioral model of eating disorders (ED) views EDs as a single disorder with different clinical manifestations, but the CBT effectiveness research thus far has mostly only pooled results within individual ED categories. A panoramic meta-analysis (PMA) synthesizes evidence across indications, and here the aim is to explore whether a PMA in the context of CBT for EDs provides an unbiased and precise effect estimate when pooling across the ED diagnoses. Methods: Reviews that synthesize RCTs of CBT for EDs were searched, and reviews that met inclusion criteria and included meta-analytic data or valid data from a single RCT were included in the PMA. Two PMAs (CBT vs active controls, CBT vs inactive controls) were performed. The outcome most commonly employed in the meta-analyses identified in the search was chosen as the outcome of interest. Findings: Of the n=24 meta-analyses, only n=7 were eligible for the PMA. The analysis provided support for the effectiveness of CBT vs inactive controls ((SMD: 0.32, 95% CI: 0.05 to 0.59, I2= 38.1%) but results were inconclusive when CBT was compared to active controls (SMD: 0.01, 95% CI: -0.35 to 0.36, I2=75.2%). Conclusions: Due to the methodological limitations of this thesis, several central comprehensive meta-analyses had to be excluded from the PMA. Thus, this PMA failed to provide a precise and unbiased synthesis of existing data of the effectiveness of CBT for EDs across the diagnoses.
