The scenario highlights that:

The client changed their thought process during anxious episodes.

Their reactions were less intense than before.

This indicates the client is applying a coping or cognitive skill learned in counseling—for example, cognitive restructuring, grounding, or other anxiety-management techniques. That is using an acquired skill (B).

A. Collaborative goal-setting is important early in treatment but does not itself explain why symptom intensity decreased.

C. Counselor’s emotional support can be helpful, but the change described is specifically tied to the client’s own cognitive work, not simply emotional support.

D. Time heals all wounds ignores the active, skill-based nature of counseling progress.

NBCC Counselor Work Behavior Areas emphasize helping clients develop, practice, and generalize skills so that they can independently manage symptoms—exactly what is described here.
