Two review studies provide systematic insights in what may promote exposure to internet delivered health promotion interventions

The Internet is considered to be a promising delivery channel of interventions aimed at promoting healthful behaviors. Exposure to these interventions, however, is generally low. A more extensive exploration of methods, strategies, and their effectiveness with regard to facilitating exposure is therefore important to improve the use of such interventions and promote healthful behavior changes. Two systematic reviews were conducted that I was involved in a s a co-author, one on studies among adolsecents, one among adults. The first study, with Dr. Rik Crutzen as firts author, is now e-published in the journal Health Education and Behavior. The review of studies among adults is available on-line, with Wendy Brouwer as first author, at the Journal of Medical Internet Research.
