Final answer:
Eclecticism in therapy involves using empirically validated treatments, is not standard practice for therapists to become skilled at multiple types of therapy, and is a common approach in therapy.
Step-by-step explanation:
The statement a is true. The matched-treatment technique in eclecticism uses empirically validated treatments that specifically address the client's presenting complaint. This approach aims to provide the most effective and evidence-based treatment.
The statement b is false. It is not standard practice for a therapist to become skilled at multiple types of therapy in eclecticism. Instead, therapists may use different approaches based on the client's needs and preferences.
The statement c is false. Eclecticism is actually a fairly common approach in therapy and is not considered experimental. Many therapists integrate different techniques and theories to customize treatment for each client.
