It appears that in practice exposure to Internet-delivered behaviour change interventions, encouraging a healthy lifestyle for adolescents with regard to health risk behaviours, is quite low. There is, however, a lack of evidence-based insight into how to disseminate such interventions and how to reach optimal exposure. A more extensive exploration is therefore timely since this knowledge is crucial to improve the public health impact of such interventions. By means of a three-round Delphi study factors associated with dissemination of and exposure (first visit, stay long enough and revisit) to Internet-delivered interventions aimed at adolescents had been identified, as well as the extent to which experts agree on the importance of these factors. Results showed that there was a high rate of consensus among experts from several disciplines with regard to the importance of factors like word of mouth recommendation, the interface of the intervention and utilization of all features provided by the Internet. Experts do not agree, however, on a gold standard for successful dissemination. Overall, the results of this exploration serve as a handle for the formation of further research questions to be tested and answered in research among adolescents.
实际上，针对青少年健康风险行为鼓励其养成健康生活方式的互联网行为改变干预措施的实际接触率似乎很低。然而，对于如何传播此类干预措施以及如何实现最佳接触率，缺乏基于证据的见解。因此，进行更广泛的探索是适时的，因为这些知识对于提高此类干预措施对公众健康的影响至关重要。通过三轮德尔菲研究，已确定了与针对青少年的互联网干预措施的传播和接触（首次访问、停留足够长时间和再次访问）相关的因素，以及专家们对这些因素重要性的认同程度。结果表明，来自多个学科的专家在诸如口碑推荐、干预界面以及互联网提供的所有功能的利用等因素的重要性方面达成了很高的共识。然而，专家们对于成功传播的黄金标准并未达成一致。总体而言，本次探索的结果为形成进一步的研究问题提供了依据，这些问题将在针对青少年的研究中进行测试和解答。
