Theory-based behavior change interventions: comments on Hobbis and Sutton.

Hobbis and Sutton (this issue) suggest that Cognitive Behavior Therapy (CBT) techniques can be used in interventions based on the Theory of Planned Behavior (TPB). Although this suggestion has merit, CBT is only one of many applicable methods for producing belief and behavior change. Moreover, CBT's primary purpose is to help people carry out intended behaviors, not to influence intentions, and that it is more useful in face-to-face than in community-level interventions. Contrary to Hobbis and Sutton's critique, TPB can accommodate core beliefs or fundamental assumptions, but the theory suggests that interventions targeted at such beliefs are less effective than interventions targeted at behavior specific beliefs.
