Cognitive and behavioral therapy approaches were increasingly combined and grouped under the umbrella term cognitive behavioral therapy (CBT) in the 1970s. Many approaches within CBT are oriented towards active/directive yet collaborative empiricism (a form of reality-testing), and assessing and modifying core beliefs and dysfunctional schemas. These approaches gained widespread acceptance as a primary treatment for numerous disorders. A "third wave" of cognitive and behavioral therapies developed, including acceptance and commitment therapy and dialectical behavior therapy, which expanded the concepts to other disorders and/or added novel components and mindfulness exercises. However the "third wave" concept has been criticized as not essentially different from other therapies and having roots in earlier ones as well. Counseling methods developed include solution-focused therapy and systemic coaching.
