What is often a critical step in the planning phase of therapy?

Setting measurable goals is indeed a critical step in the planning phase of therapy because it provides a clear and structured framework for both the therapist and the client. Measurable goals help to define what success looks like and establish benchmarks for progress throughout the therapeutic process. These goals serve as a guide for decision-making, allowing for adjustments in the treatment plan as needed based on the client's development and feedback.

Additionally, having measurable goals increases accountability for both the client and the therapist, fostering motivation and engagement. Clients can more easily track their own progress, which is essential for maintaining commitment to the therapeutic process. Furthermore, these goals can facilitate communication between the therapist and other stakeholders, such as family members or other health professionals involved in the client's care.

While the other options presented—choosing the therapy modality, evaluating past treatment outcomes, and gathering additional resources—are all important elements of the planning phase, they do not carry the same critical weight as establishing measurable goals. They may support the process, but measurable goals directly impact the direction and effectiveness of therapy.
