What is one factor mentioned by Duncan, Humble, and Miller in the blended model?

The factor mentioned by Duncan, Humble, and Miller in the blended model is therapeutic relationship quality. This emphasizes the importance of the interpersonal connection between the therapist and the client, which is essential for effective treatment. A strong therapeutic relationship fosters trust, collaboration, and engagement, allowing clients to feel safe and understood, which can significantly enhance the overall effectiveness of therapy.

In this context, the other options focus on structural or procedural aspects of supervision. Supervisor authority mandates, for instance, pertain to the formal rules governing the supervisory relationship rather than the emotional or relational aspects. Similarly, direct guidance from management deals with organizational directives that may not prioritize the nuances of interpersonal dynamics. Standardized treatment plans, while important in ensuring consistency in care, do not capture the essence of the relational quality that is pivotal in the blended model. By highlighting therapeutic relationship quality, Duncan, Humble, and Miller underscore a key component of effective therapeutic interventions that transcends mere procedures or authority structures.
