BACKGROUND
Smoking cessation support on Facebook (FB) is a cost-effective and extensible way to reduce tobacco use among young people. Motivational interviewing (MI) is a practical counselling style in face-to-face smoking cessation support and can be useful in web-based interventions as well.
OBJECTIVE
This study aimed at identifying which post creation strategies based on MI could achieve positive changes in FB post characteristics and FB users’ comments.
METHODS
We included MI-adherent posts (N=701) which were not boosted and were targeted at tobacco users. These FB posts have been categorized into five different groups according to specific MI strategies. The control group comprised entertaining and informative posts. Primary outcomes seem to highlight how the content has stimulated interactions (engagement rate), inhibited interactions (negative feedback) or appealed to the audience of the FB page (fan-total reach ratio). The first comments received on the FB posts were evaluated and used as secondary outcomes. We applied the classification of MI approach: change talk (CT), sustain talk (ST), desire, ability, reason, need (DARN), and commitment, activation, taking steps (CAT).
RESULTS
FB posts which used MI strategies were associated with significantly higher engagement rate (p=.010), higher fan-total reach ratio (p<.001), and more CT (p<.001), DARN (p=.005), or CAT comments (p=.003) compared to the control group. ‘Elaborating CT’ strategies elicited considerably more CT (p<.001) and DARN comments (p=.020). ‘Affirming CT’ strategies obtained higher fan-total reach ratio (p=.011) and generated significantly more CT (p=.006) and CAT comments (p<.001). ‘Reflecting CT’ strategies received significantly higher fan-total reach ratio (p<.001). Finally, ‘relational MI’ strategies achieved significantly higher engagement rate (p<.001) compared to the control group. It should be noted that we did not find significant difference in negative feedback and the number of ST comments.
CONCLUSIONS
Post creation strategies based on MI stimulated interactions with FB users and generated conversation about tobacco use cessation without relevant negative feedback. Our findings suggest that MI strategies may play a remarkable role in post creation within a web-based smoking cessation intervention. In the future, these strategies could be applicable to other online platforms, such as public health websites, health blogs, mobile applications or social networking groups.
