Clinical behavior analysis

Clinical behavior analysis (CBA; also called clinical behaviour analysis or third-generation behavior therapy) is a clinical application of behavior analysis (ABA). CBA represents a movement in behavior therapy away from methodological behaviorism and back toward radical behaviorism and functional analytic models of verbal behavior—particularly, relational frame theory (RFT).

Cognitive-behavioral therapies (CBTs) such as acceptance and commitment therapy (ACT), community reinforcement approach and family training (CRAFT), behavioral activation (BA), functional analytic psychotherapy (FAP), integrative behavioral couples therapy, dialectical behavioral therapy (DBT), systematic desensitization, and contingency management (CM). Behavioral medicine has three forms: behavioral pharmacology, behavioral pediatrics, and behavioral gerontology.

Acceptance and commitment therapy is probably the most well-researched of all the third-generation behavior therapy models. Its development co-occurred with that of relational frame theory, with several researchers such as Steven C Hayes being involved with both. ACT has been argued to be based on relational frame theory, although this is a matter of some debate within the community. Originally this approach was referred to as comprehensive distancing. Every practitioner mixes acceptance with a commitment to one's values. These ingredients become enmeshed into the treatment in different ways which leads to ACT being either more on the mindfulness side or more on the behavior-changing side. ACT has, as of September 2015, been evaluated in over 130 randomized clinical trials for a variety of client problems. Overall, when compared to other active treatments designed or known to be helpful, the effect size for ACT is a Cohen's d of around 0.6, which is considered a medium effect size.
