As you probably already know, dealing with addiction is tricky. If you want to help someone, you must be sensitive to their needs and their situation. As a counselor, you need to be motivated to research the latest studies on ways to help addicts and be willing to try new techniques.
Give an example that demonstrates your knowledge and understanding of the issue. If you have a success story, share it! Be sure to explain the approach and why it has been helpful in treatment.
"Motivational interviewing is a technique I've found extremely helpful with my patients. As they further understand the reasons behind their behaviors, they develop an awareness that triggers a new desire to change their behaviors."
Entry Level answer example
"I'm always happy to learn new approaches. I've been lucky to have senior counselors in my current position to learn from. I can't say what has been and hasn't been successful because what works for one, sometimes doesn't work for others."
Experienced answer example
"I am open to trying new therapies with a variety of patients, at all times. With that said, my tried and true method is Cognitive Behavior Therapy. I find that by creating a pre-meditated strategy to risky situations, it helps to prevent patient relapse."
