Which response best exemplifies the affirmation skill in motivational interviewing?

Affirmation in motivational interviewing involves recognizing and appreciating an individual's strengths and efforts, helping to build their confidence and reinforce positive behavior. The response that captures this very essence is one that expresses gratitude and acknowledges the positive act of sharing concerns. By saying, "Thank you for sharing your concerns with me, I enjoyed speaking with you today," the speaker is affirming the individual's willingness to engage in dialogue, which fosters a supportive and collaborative environment. This acknowledgment not only reinforces the individual's behavior of opening up but also strengthens the therapeutic relationship, making the individual feel valued and understood.

The other options focus on different aspects of communication. One may express empathy or encourage further dialogue, but they do not specifically serve to affirm the individual's abilities or efforts in the way that the selected response does. Therefore, in the context of motivational interviewing, the chosen response effectively exemplifies the affirmation skill by reinforcing positive interaction.
