Purpose: The purpose of this paper is to gain first insight into factors which might be associated with exposure to internet-delivered interventions. Design/methodology/approach: Semi-structured focus group interviews were conducted with five groups of Dutch adolescents (n = 54), aged 12-17 years. Several aspects of exposure: a first visit; staying long enough actually to use and process the information; and revisiting the intervention, were explored. Findings: Several factors that are likely to improve exposure to internet-delivered interventions were identified, such as the use of "word of mouth" marketing, comparison of own behaviour with friends and the use of reminders. Research limitations/implications: Focus group interviews are only a first step in the generation of ideas and opinions. A next step would be to conduct observational, experimental and longitudinal studies to test "if" and "how" these factors improve exposure to internet-delivered interventions. Practical implications: This paper is a useful source for those developing internet-delivered interventions who want to improve exposure rates to their interventions. Originality/value: The results of this exploration serve as an important first step to gain more insight into factors that improve exposure to internet-delivered interventions. (Contains 1 table.)
