Evaluation of a motivational interviewing informed workshop for trainees in a diabetes prevention program in the community


Objectives: Utilizing Kirkpatrick's four-level model this study presents the evaluation of a two-day Motivational Interviewing (MI) informed workshop on trainee's satisfaction, MI-knowledge, MI-skills, and applying MI in a community-based diabetes prevention program. Methods: Four students provided feedback on the content of the MI-informed workshop. Seven other trainees took part in its evaluation. MI-skills were evaluated using a vignette (Helpfulness Response Questionnaire; HRQ) at pre- and post-workshop. The Motivational Interviewing Competency Assessment (MICA) was used to code trainee's audio recordings with clients from the diabetes prevention program. The MICA provides a total score for MI competency and scores on seven MI categories. Results: Average age was 24 years (SD = 2.8), 85% were women, and 57.2% had less than a bachelor degree. The workshop was perceived as highly satisfactory (M = 4.7, SD = 0.41, out of 5). MI-knowledge and MI-confidence increased from pre- to post-workshop (p < .001, ?2p= .95 and p = .003, ?2p = .79, respectively). As expected, the HRQ reflective statements increased relative to asking questions from pre- [R/OQ]=27/25 to post-workshop[R/OQ]=40/29. Despite the short training, 50% of the trainees' MI-skills were classified as client-centered (MICA ?3/5) on all MI categories, but the trainees did not reach overall level of MI competency (MICA ?8/10), with M = 5.8 (SD = .99). Conclusions: Consistent with previous research, this brief training improved MI-knowledge and MI-skills, but it was less effective for overall application of MI. Future work will integrate booster sessions to evaluate the addition of supervised practice on outcomes.
