  4. Once upon a time… there was the Internet • Great potential • Increasing number of interventions

  5. Problem • Possibly effective in behaviour change • Low exposure rates

  6. Terminology • Dissemination • Exposure • Accessing • Staying • Revisiting

  7. Adolescents • Many health risk behaviours are acquired during adolescence • Grew up with the Internet • Not likely to be internally motivated

  8. Outline • Explorative research • Systematic review • Delphi study • Focus group interviews • Applied research • Effectiveness of strategies • Generalising to multiple behaviours • Tracking exposure

  9. Dissemination • Embedding in a social context • Cross-medial promotion • Ambiguous picture • Research setting

  10. Exposure: accessing • Recommendations through WOM • Attractive interface at first sight

  11. Exposure: staying • Look and feel • Visual material and interactive features • Content  purpose • Credibility

  12. Exposure: revisiting • Commitment • New content • Monitoring

  13. Measuring exposure • Heterogeneous measures • More insight into intensity of exposure • Potentially mediating effects

  14. Questions?

  15. Considerations • If the mountain will not come to Mahomet, should Mahomet go to the mountain? • When is dissemination successful? • How could strategies which aim to improve dissemination and exposure be tested on effectiveness?

  16. Consideration #1 • If the mountain will not come to Mahomet, should Mahomet go to the mountain? • Awareness • Popular online places • Reason to visit • Collaborations

  17. Consideration #2 • When is dissemination successful? • Absolute figures • Denominator • Cut off point • Methods of analysis

  18. Consideration #3 • How could strategies which aim to improve dissemination and exposure be tested on effectiveness? • Controlled settings • Time series design • Intervention x user
