This is a tough question! There are several skills that are absolutely essential for an addiction counselor. You need to be assertive enough to facilitate discussions and direct a patient, but you also need to listen and empathize. What characteristics do you think are the most important? Try to narrow it down and explain exactly why it's necessary for you to possess that trait.
"I think all counselors should have public speaking skills. Being able to address a group of patients in group therapy sessions is something that I'm very comfortable with."
"An important skill that every addiction counselor should posses is the ability to take clear and informative notes. My detailed and accurate notes come in handy if we have to transfer a patient to a different facility, for instance."
"In my years of experience as an addictions counselor, I have found that the ability to quickly build trust is the most important factor to success with a patient. If I am able to make a connection in a short period of time, my sessions are more effective."
