Background: In Canada, only 15% of adults meet the physical activity guidelines (Colley et al., 2011). As regular physical activity has been demonstrated to substantially improve physical and mental health (Naci & Ioannidis, 2013; Schuch et al., 2016), a wealth of physical activity promoting interventions have been developed and evaluated (Kahn et al., 2002; Prince et al., 2014). Physical Activity Counselling (PAC) is one of these and has been shown effective in increasing physical activity motivation and behaviour (Fortier et al., 2011). However, the active ingredients of PAC have never been reported in detail, thus limiting our potential for understanding its effectiveness and to allow for its replication. Recently, taxonomies have been published for characterizing behaviour change techniques (BCTs) and Motivational Interviewing (MI) techniques in interventions (Hardcastle et al., 2017; Michie et al., 2013). Due to its novelty, no studies to date have used the MI technique taxonomy to report interventions.
Purpose: To investigate the behaviour change techniques (BCTs) and Motivational Interviewing (MI) techniques applied in PAC sessions delivered by student-counsellors.
Methods: PAC 1 and PAC 2 sessions delivered by 11 student-counsellors were double coded for identification of BCTs and MI techniques, for a total of 22 video recorded sessions. Two trained coders rated the presence of BCTs and MI techniques using the Behaviour Change Technique Taxonomy v1 (BCTTv1) and the table of MI techniques. Inter coder agreement was assessed using Cohen’s kappa and the prevalence- and bias-adjusted kappa (PABAK) statistic.
Results: Overall, 29 BCTs (on 93) and 27 MI techniques (on 38) were reliably coded across the sampled PAC sessions (Cohen’s k =.81, PABAK=.91). Popular BCTs included 3.1 Social support (unspecified), 1.1 Goal setting (behaviour), 1.4 Action planning, whereas OARS skills (i.e., open-ended questions, affirmations, reflective and summary statements) and 24. Emphasize autonomy were the predominating MI techniques. On average, 5.7 BCTs and 9.5 MI techniques were recorded per session.
Conclusions: Findings of this study provide a first detailed report of a PAC intervention and have important implications for PAC training and replication. Future research in this area specifically looking at the quality of application of the techniques and the influence of use and quality on physical activity behaviour over time is recommended.
