Effectiveness of training final-year undergraduate nutritionists in motivational interviewing

Abstract

Objectives: To assess the efficacy of a motivational interviewing (MI) training programme on trainee nutritionists.

Methods: A repeated measures design was applied to assess clinician behaviours in a 'helping' conversation. Participants were 32 nutrition students, assessed at baseline and one-month follow-up.

Results: The training significantly reduced the use of closed questions and MI non-adherent behaviours (MINA) (P for both=<0.001). Trainees significantly increased reflections, affirmations, summaries (P for all=<0.001) and the use of open questions (P=<0.013) which are all key indicators of MI beginner-competence. The talk-time ratio of the nutritionists also changed significantly, in favour of the client which serves as an indication of MI being used effectively. There were also significant increases in 'global' scores for empathy, direction, autonomy/support, collaboration and evocation.

Conclusions: Newly trained nutritionists 1 month post-training have a consultation style which suggested positive outcomes for clients. The trainees' scores at the one month post-training assessment were verifiable as 'beginning proficiency'.

Practice implications: Behaviour change counselling skills for nutritionists were enhanced, at one month post-training. MI training workshops with video feedback enhances communication skills which are likely to lead to positive consultation-behaviour changes in the trainee nutritionists.
