Cognitive Behavior Therapy (CBT) is grounded in the understanding that psychological distress often arises from dysfunctional thought patterns and behaviors. The biopsychosocial model underlying CBT asserts that distress results from the interplay of biological, psychological, and social factors. CBT helps clients identify and modify negative thought patterns, which in turn influence emotional and behavioral responses.
Thus, the correct answer is Cognitive behavior therapy, which focuses on the client’s thought processes, behaviors, and the influence of their social and biological contexts.
