Motivational Interviewing: Does It Increase Clients' Retention in Intensive Outpatient Treatment?

Motivational Interviewing (MI) is a clinical technique that has received considerable attention in the addictions arena over the past decade. In the present pilot study, the impact of providing up to five MI sessions during the first two weeks of intensive outpatient treatment (IOP), relative to the treatment as usual was addressed. The participants were 106 IOP patients, and a post-test design was utilized. Results showed that adding MI sessions during the first two weeks of IOP did not increase the number of days in treatment nor was there an increase in treatment completion. It is possible that the MI sessions by themselves were not sufficient to offset factors that were contributing to less than optimal treatment involvement.
