简要总结
The goal of this evaluation study is to evaluate the KickAsh! intervention, an intervention aiming to prevent smoking initiation in adolescents living in vulnerable socioeconomic situations. This intervention will be implemented in youth social work organisation that offer sport and/or recreational activities for these adolescents. Youth workers will act as implementers of the intervention.
The main aim of this study is to evaluate the effect of the intervention, whether it does or does not produce change in the smoking initiation behaviour of adolescents (= effect evaluation). Secondly, the study aims to evaluate the implementation process to generate more understanding concerning why the intervention does or does not produces change. Therefore, it will be investigated how the intervention was implemented, what exactly was implemented, in which context the intervention was implemented... (= process evaluation)
For the effect evaluation adolescents will be asked to fill in a questionaire at three time points. For the process evaluations interviews and focus groups will be organised with the adolescents and youth workers respectively.
Two groups will participate to this study: one group existing of organisations where the intervention will be implemented (=intervention group), and one group where the intervention will not be implemented (= control group).

结局指标
主要结局
Change in smoking initiation behaviour at 3 months
时间窗: From enrollment to the end of intervention implementation at 3 months
Smoking initiation will be measured following MUSICA: the Model of Unplanned Smoking Initiation of Children and Adolescents. In addition, two questions will be asked concerning smoking frequency in the past month and in adolescents life. Smoking onset age and smoking intention in the following year an d the future are also questioned.
Change in smoking initiation behaviour at 6 months follow-up
时间窗: From end of intervention implementation to follow-up measurement after 6 months
