Task Force Report on methodology and empirically supported treatments: introduction.

Recent criticism of biofeedback has increased the importance of rating the efficacy of each biofeedback and neurofeedback therapy. A joint task force of the Association for Applied Psychophysiology and Biofeedback (AAPB) and the Society for Neuronal Regulation (SNR) has developed standards for efficacy research methodology and template for rating the level of efficacy of each application. The Task Force Report has been approved as a policy guideline by both the AAPB and SNR Boards.
