A meta-analysis of health communications examines the influence of 22 tactics and six individual characteristics on intentions to comply with health recommendations. The analysis indicates that message tactics have a significant influence on intentions toward health-related recommendations even after the authors account for individual differences. In addition, the authors examine when message tactics interact with individual characteristics to determine intentions. The results, which are based on 60 studies involving nearly 22,500 participants, show that there is significant opportunity to tailor health communications more efficiently to different market segments.
