A framework to guide storytelling as a knowledge translation intervention for health-promoting behaviour change

BACKGROUND: Stories can be a powerful tool to increase uptake of health information, a key goal of knowledge translation (KT). Systematic reviews demonstrate that storytelling (i.e. sharing stories) can be effective in changing health-promoting behaviours. Though an attractive KT strategy, storytelling is a complex approach requiring careful planning and consideration of multiple factors. We sought to develop a framework to assist KT researchers and practitioners in health contexts to consider and develop effective KT interventions that include stories or storytelling. METHODS: We conducted a broad search of the literature to identify studies that used storytelling as a KT intervention across different disciplines: health research, education, policy development, anthropology, organizational development, technology research, and media. We extracted purposes, theories, models, mechanisms, and outcomes and then mapped the theoretical and practical considerations from the literature onto the Medical Research Council guidance for complex interventions. The theoretical and practical considerations uncovered comprised the basis of the storytelling framework development. Through discussion and consensus, methodological experts refined and revised the framework for completeness, accuracy, nuance, and usability. RESULTS: We used a complex intervention lens paired with existing behaviour change techniques to guide appropriate theory-based intervention planning and practical choices. An intentional approach to the development of story-based KT interventions should involve three phases. The theory phase specifies the goal of the intervention, mechanisms of action, and behaviour change techniques that will achieve the intended effects. The modelling phase involves development and testing using an iterative approach, multiple methods and engagement of end-users. Finally, formal evaluation using multiple methods helps determine whether the intervention is having its intended effects and value added. CONCLUSIONS: This framework provides practical guidance for designing story-based KT interventions. The framework was designed to make explicit the requisite considerations when determining the appropriateness and/or feasibility of storytelling KT, clarify intervention goals and audience, and subsequently, support the development and testing of storytelling interventions. The framework presents considerations as opposed to being prescriptive. The framework also offers an opportunity to further develop theory and the KT community’s understanding of effectiveness and mechanisms of action in storytelling interventions.
