Answer:
Bernie's progress will hinge on the perceived level of trust which he feels.
Explanation:
Trust is not only the result, but also a preceding condition to the establishment of a therapeutic relationship. When a patient does not feel he can trust the therapist, he does not feel comfortable to open up and share his experiences and emotions, much less to accept any insight coming from the therapist. Bernie will only experience progress in therapy if he senses he can fully trust his therapist, which will make their interactions more comfortable.
