Clinician-Reported Modification to a CBT Approach in Children’s Mental Health:

Examining the nature and determinants of evidence-based treatment (EBT) modification is an important step toward understanding the impact of modifications and informing modification guidelines. We examined the prevalence, types, reasons for, and predictors of clinician-reported modification to cognitive behavioral therapy (CBT) for children and adolescents. Ninety-eight clinicians trained in CBT completed surveys on their intent to modify CBT, perceptions of CBT characteristics, confidence in their ability to appropriately deliver CBT in complex clinical situations, and organizational EBT implementation climate post-training. Post-consultation, clinicians self-reported the types and reasons for modifications they performed. Ninety-three percent of clinicians reported they modified CBT, primarily with fewer than half of their clients. Client needs and clinician preference or style accounted for the highest proportion of modification reasons. The number of reported modifications performed was predicted by clinician confidence in their ability to deliver CBT appropriately (b = .90, p = .01) and their intent to modify (b = .55, p = .01).
