The independent mobility (IM), defined as the freedom of young people to travel without adult supervision, has been related to the physical activity time, the acquisition of personal autonomy, to less intense fear of crime, and to a stronger feeling of being part of their community and other health and social benefits. The aims of this study were to compare parents' and adolescents' traffic- and crime-related safety perceptions of their neighborhood and to analyze the associations of these perceptions with adolescents' IM. A total of 291 adolescents and their parents completed the Neighborhood Environment Walkability Scale (NEWS) questionnaire. Multilevel (two-level models: individual level-neighborhood level) regression analyses were conducted to examine whether the environmental perceptions differed between parents and adolescents and the association between the parental and adolescents' perception to the IM and the active independent mobility (AIM). Parents reported a more negative perception of traffic (except for amount and speed) and crime-related safety. Adolescents' environmental perceptions were not associated with their IM but parental perceptions of traffic- and crime-related safety were associated with IM and with active IM, although not all associations were in the expected direction. Future urban policy efforts should address environments where parents perceive sufficient levels of safety to increase the levels of IM in adolescents.
独立出行（IM）是指年轻人在没有成人监督的情况下自由出行，与他们的体育活动时间、获得个人自主权、较少的犯罪恐惧以及更强的社区归属感等健康和社会效益有关。本研究旨在比较父母和青少年对其居住环境的交通和犯罪相关安全的看法，并分析这些看法与青少年独立出行之间的关系。共有 291 名青少年及其父母完成了邻里环境步行能力量表（NEWS）问卷。采用多层次（个体水平-邻里水平）回归分析，检验父母和青少年的环境感知是否存在差异，以及父母和青少年对交通和犯罪相关安全的感知与独立出行和积极独立出行（AIM）的关系。父母对交通（除了数量和速度外）和犯罪相关安全的感知更负面。青少年的环境感知与他们的独立出行没有关系，但父母对交通和犯罪相关安全的感知与独立出行和积极独立出行有关，尽管并非所有关联都符合预期方向。未来的城市政策努力应针对父母认为安全水平足够的环境，以提高青少年的独立出行水平。
