The rationale behind ______ therapy is that the client's distress has its origins in the biological, psychological and social realms.

Cognitive behaviour therapy

The correct answer is Option (2) → Cognitive behaviour therapy

Cognitive Behaviour Therapy:  The most popular therapy presently is the Cognitive Behaviour Therapy (CBT). Research into the outcome and effectiveness of psychotherapy has conclusively established CBT to be a short and efficacious treatment for a wide range of psychological disorders such as anxiety, depression, panic attacks, and borderline personality, etc. CBT adopts a bio-psychosocial approach to the delineation of psychopathology. It combines cognitive therapy with behavioural techniques. The rationale is that the client’s distress has its origins in the biological, psychological, and social realms. Hence, addressing the biological aspects through relaxation procedures, the psychological ones through behaviour therapy and cognitive therapy techniques and the social ones with environmental manipulations makes CBT a comprehensive technique which is easy to use, applicable to a variety of disorders, and has proven efficacy.
