The principle of cross-level interactions of influence on behavior in ecological models is seldom studied.
To examine built environment × psychosocial interactive effects on physical activity.
Multi-level mixed regression analyses used data from the Neighborhood Quality of Life Study conducted in neighborhoods in two US regions (n = 2,199 adults). Outcomes were (1) objectively measured moderate-to-vigorous physical activity, (2) reported transport walking, and (3) leisure-walking. Conceptually matched built environment variables were analyzed for domain-specific outcomes.
With leisure walking as the outcome, built environment × psychosocial interactions were significant in 7 of 20 models tested. Directions of interactions were consistent, indicating a stronger built environment-leisure walking association in adults with less favorable psychosocial status. Little evidence supported such interactions with objectively measured moderate-to-vigorous physical activity or transport walking as outcomes.
The results imply that the built environment may exert stronger influence on adults who are not psychologically predisposed to be active.
生态模型中影响行为的跨层次相互作用原则很少得到研究。
检验建筑环境与心理社会的相互作用对身体活动的影响。
使用来自美国两个地区社区的邻里生活质量研究（n=2199 名成年人）的数据进行多层次混合回归分析。结果是：（1）客观测量的中等至剧烈身体活动，（2）报告的交通步行和（3）休闲步行。对概念上匹配的建筑环境变量进行了特定领域结果的分析。
以休闲步行作为结果，在 20 个测试模型中有 7 个显示出建筑环境与心理社会的相互作用是显著的。相互作用的方向是一致的，表明在心理社会状态较差的成年人中，建筑环境与休闲步行的关联更强。很少有证据支持将客观测量的中等至剧烈身体活动或交通步行作为结果的这种相互作用。
结果表明，建筑环境可能对那些没有心理倾向于积极活动的成年人产生更强的影响。
