Purpose: To investigate the impact of a one-day workshop in Motivational Interviewing (MI) on health care practitioners’ perceived competence, perceived autonomy, and experiences and attitudes towards facilitating behaviour change among patients.

Methods: This single subject multiple baseline design study targeted a sample of 10 health practitioners. One-on-one interviews were conducted prior to the workshop and at one and four weeks post-training. Participants completed a series of questionnaires multiple times prior to and following the workshop. Results: Participants described improvements in their abilities to facilitate behaviour change following the workshop. Significant increases in perceived competence (Cohen’s effect size £=4.61), perceived autonomy (¿^=1.62), practitioner efficacy (d=2.22), and behaviour change in routine care (<£=1.69) were reported. Discussion: Participation in the workshop was effective. Allied health care practitioners are in key positions to facilitate health behaviour changes that contribute to behaviour-related illness. The integration of MI should be explored further with a larger group.
