In the blended model, what accounts for 15% of therapeutic change related to clients' expectations?

The correct answer, which is "placebo factors," highlights the significant role that clients' expectations play in therapeutic change. In the context of a blended model of therapy, placebo factors represent the power of belief and expectation in the outcomes of treatment. When clients have faith in the efficacy of the therapy they are receiving or believe that their engagement in the therapeutic process will lead to positive changes, this can enhance their overall experience and effectiveness of the treatment.

These expectations can lead to physiological changes and increase motivation, which are critical to the therapeutic process, explaining why they contribute to 15% of the overall therapeutic change. The placebo effect serves as a reminder that the mind’s expectations significantly influence the body’s responses, and in therapeutic contexts, this can translate to improved outcomes for clients as they engage with their treatment.

Understanding placebo factors is vital for practitioners, as it encourages them to foster clients' positive expectations and beliefs about the treatment process, which can be invaluable in enhancing therapeutic effectiveness.
