Best Answer: C. If a psychoanalytic client is not improving despite gaining insights, the therapist might consider integrating elements of cognitive-behavioral therapy (CBT). Research suggests that CBT can be effective for various issues, including anxiety and trauma-related disorders. It offers practical coping strategies and skills for managing distressing symptoms, which might be beneficial in this case. Existential therapy (A), narrative therapy (B), and person-centered therapy (D) are less likely to be chosen in this context, as they do not typically incorporate the symptom-focused and skills-based approaches of CBT.
