Narrative interventions for health screening behaviours: A systematic review.

Health information can be presented in different formats, such as a statistically-based or a story-based (e.g. narrative) format; however, there is no consensus on the ideal way to present screening information. This systematic review summarizes the literature pertaining to narrative interventions' efficacy at changing screening behaviour and its determinants. Five psychology and public health databases were searched; 19 studies, 18 focused on cancer and 1 on sexual health, met eligibility criteria. There is consistent evidence supporting the efficacy of narratives, but mixed evidence supporting an advantage for narratives over statistical interventions for screening behaviour and its determinants. Further investigation is warranted.
