Cognitive behavioral therapy's main strategies are active, problem-focused, and collaborative. Cognitive restructuring is a strategy in which clinicians help patients to identify, evaluate, and modify inaccurate or otherwise unhelpful thinking associated with emotional distress. Behavioral activation provides a framework for patients, particularly those who are depressed, to increase engagement in activities that provide a sense of accomplishment or pleasure. The goal of exposure is for anxious patients to experience an extinction of fear by having planned contact with feared stimuli and situations. Problem solving allows patients to systematically approach and address their life problems by using cognitive and behavioral techniques.
