e-Health intervention development: a synopsis and comment on “What Design Features are Used in Effective e-Health Interventions? A Review Using Techniques From Critical Interpretive Synthesis”

In this synopsis and commentary on the Morrison and colleagues article published in Telemedicine and e-Health (18:2, 137–144, 2012), we provide a brief review of effective design features of e-Health interventions as well as a discussion on future directions. The Internet is being used more frequently to deliver health behavior interventions; however, it is unclear which design features contribute to intervention outcomes. Morrison and colleagues conducted a review using critical interpretive synthesis techniques to identify design features that mediate the effects of e-Health intervention outcomes. A total of four design features were identified (social context and support, contacts with intervention, tailoring, and self-management) that may mediate the effect of the intervention on outcomes. This review provides a preliminary conceptual framework to guide future evaluations of the effects of e-Health design features on intervention outcomes. Future research should target optimizing e-Health interventions to determine which design features should be included as well as how they contribute to outcomes.
