Effect of a Short Smoking Cessation Training Session on Smoking Cessation Behavior and Its Determinants Among General...

Inadequate smoking cessation interventions by physicians have been attributed to lack of training, and it is generally thought that additional education will improve patient care. However, interventions aimed at increasing knowledge and practical skills only address one determinant of behavior (capability). This prospective study assessed how much a teaching session for general practitioner (GP) trainees enrolled in Vocational Training Schemes in England also affected two other determinants (motivation and opportunity) specified by the COM-B theory of behavior.

Between October and December 2015, GP trainees were given a 3.5-h training session in the theory and practice of smoking cessation. Questionnaires addressed motivation, capability, and opportunities to provide evidence-based brief advice to smokers at the beginning and end of the session, and 3 months later. They also looked at the recollection of previous teaching as well as knowledge, skills, intervention frequency, and perceived barriers against providing interventions.

Participants (n = 123) remembered little previous training on the subject and self-reported presession knowledge was minimal. Motivation was high throughout while capability and opportunity increased considerably during the session. No further change in these parameters was noted at 3 months. The proportion of participants stating they provided evidence-based brief advice to >50% of smokers increased from 25.2% before the session to 57.7% at follow-up. Lack of time remained a commonly cited barrier.

Training elicited an immediate and sustained effect on capability, perceived opportunity, and behavior itself. While perceived barriers referring to capability were greatly reduced, barriers referring to opportunity (eg, lack of time) persisted.

This is the first study evaluating a GP training session on smoking cessation with regard to the COM-B model. In a pre-post design with 3-month follow-up, we observed substantial and sustained changes in GP trainees' perceived capability and opportunity to provide evidence-based very brief advice, and these increases were paralleled by favorable changes in practice behavior.
