In order to be able to tailor environmental interventions to adolescents at risk for low levels of physical activity, the aim of the present study is to identify subgroups of adolescents with different physical and social environmental preferences towards cycling for transport and to determine differences in individual characteristics between these subgroups. In this experimental study, 882 adolescents (12-16 years) completed 15 choice tasks with manipulated photographs. Participants chose between two possible routes to cycle to a friend's house which differed in seven physical micro-environmental factors, cycling distance and co-participation in cycling (i.e. cycling alone or with a friend). Latent class analysis was performed. Data were collected from March till October 2016 across Flanders (Belgium). Three subgroups could be identified. Subgroup 1 attached most importance to separation of the cycle path and safety-related aspects. Subgroup 2 attached most importance to being able to cycle together with a friend and had the highest percentage of regular cyclists. In subgroup 3, the importance of cycling distance clearly stood out. This subgroup included the lowest percentage of regular cyclists. Results showed that in order to stimulate the least regular cyclists, and thus also the subgroup most at risk for low levels of active transport, cycling distances should be as short as possible. In general, results showed that providing well-separated cycle paths which enable adolescents to cycle side by side and introducing shortcuts for cyclists may encourage different subgroups of adolescents to cycle for transport without discouraging other subgroups.
为了能够针对低水平身体活动风险的青少年量身定制环境干预措施，本研究旨在确定对自行车交通具有不同身体和社会环境偏好的青少年亚组，并确定这些亚组之间个体特征的差异。在这项实验研究中，882 名青少年（12-16 岁）完成了 15 项带有操纵照片的选择任务。参与者在两条可能的路线之间选择骑自行车去朋友家，这两条路线在七个物理微观环境因素、骑行距离和共同参与骑行（即独自骑行或与朋友一起骑行）方面有所不同。进行了潜在类别分析。数据于 2016 年 3 月至 10 月在佛兰德（比利时）收集。可以确定三个亚组。第 1 组最重视自行车道的隔离和与安全相关的方面。第 2 组最重视能够与朋友一起骑自行车，并且定期骑自行车的比例最高。在第 3 组中，骑自行车的距离明显很重要。这一组包括定期骑自行车的比例最低的青少年。结果表明，为了鼓励最少的定期骑自行车的人，也就是最有可能低水平进行主动交通的群体，骑自行车的距离应该尽可能短。总的来说，结果表明，提供分隔良好的自行车道，使青少年能够并排骑行，并为骑自行车者引入捷径，可能会鼓励不同的青少年亚组选择骑自行车进行交通出行，而不会使其他亚组感到气馁。
