Final answer:
Collaborative empiricism is the partnership between a cognitive-behavioral therapist and the client to identify and challenge distorted thoughts and behaviors, which is essential in cognitive-behavioral therapy.
Step-by-step explanation:
The statement Collaborative empiricism involves a cognitive therapist's collaboration with colleagues on a client's case is false. Collaborative empiricism actually refers to the collaboration between the therapist and the client rather than between colleagues. In cognitive-behavioral therapy, this partnership is crucial as the therapist and client work together to identify, examine, and challenge distorted cognitions and behaviors to overcome psychological obstacles. The collaboration may include tasks such as homework assignments, behavioral experiments, and problem-solving, all designed to test the validity of cognitive distortions and develop more balanced and helpful thoughts and beliefs.
