Behavioral psychotherapy is a type of psychotherapy from the behaviourism tradition, and one of two streams of thought (the other being cognitive psychotherapy) that have come together to produce cognitive behavioral therapy.
Behavioral psychotherapy has a rich tradition in research and practice. From a purely behavioral perspective, behavior therapy has shown considerable success with clients from a variety of problems. Traditional behavior therapy draws from respondent conditioning and operant conditioning to solve client problems.
Behavioral therapy based on operant and respondent principles has considerable evidence base to support its usage. This approach remains a vital area of clinical psychology and is often termed clinical behavior analysis. Behavioral psychotherapy has become increasingly contextual in recent years. Behavioral psychotherapy has developed greater interest in recent years in personality disorders as well as a greater focus on acceptance and complex case conceptualizations.
One current form of behavioral psychotherapy is functional analytic psychotherapy. Functional analytic psychotherapy is a longer duration behavior therapy. Functional analytic therapy focuses on in-session use of reinforcement and is primarily a relationally-based therapy. As with most of the behavioral psychotherapies, functional analytic psychotherapy is contextual in its origins and nature. and draws heavily on radical behaviorism and functional contextualism.
Functional analytic psychotherapy holds to a process model of research, which makes it unique compared to traditional behavior therapy and cognitive behavioral therapy.
