本研究采用层次结构方程模型和多维度的3周家庭时间使用和活动日记，在印度尼西亚万隆大都市区进行，研究了个人非工具变量、时间空间（如他们每天参与活动的时间持续时间、社会人口统计学和建筑环境）和健康因素对个人日常自由活动的相互作用。结果表明，个体的主观特征和日常时间空间成分显著影响参与某些活动的决策过程，特别是杂货购物。主观因素和日常活动参与时间之间的整合也揭示了个体如何将特定行为归类为常规，计划或冲动。例如，在杂货店购物是一种有计划的行为，会产生实际的后果（例如，挨饿）。表现出强烈的承诺和意愿，使个人能够分配时间参与这项活动。因此，考虑到个体的时空限制，在频率和持续时间之间可能有规律的权衡。另一方面，户外社交娱乐活动是一种不那么紧急/冲动的活动，它更多地取决于个人的日常时空限制，而不是他/她的主观特征。如果当天的情况不适合他/她进行户外社会娱乐活动，他/她更有可能重新安排活动。研究结果还表明，土地利用结构和可达性对个体的自由活动参与有影响。
Using a hierarchical structured equation model and a multi-dimensional 3-week household time-use and activity diary conducted in Bandung Metropolitan Area, Indonesia, this study investigated the interaction among individuals' non-instrumental variables, time space (such as their day-to-day time duration of activity participation, socio-demographics and built environment), and health factors on individuals' day-to-day discretionary activities. The results show that individuals' subjective characteristics and day-to-day time-space components significantly influence decision making processes to participate in certain activities, particularly grocery shopping. Integration between subjective factors and day-to-day time duration of activity participation also reveals how an individual categorises a particular behaviour as routine, planned or impulsive. For example, grocery shopping is a planned behaviour with real consequences (e.g. starving). Appearing as a strong commitment and intention enables individuals to allocate time to engage in this activity. Thus, given the individual's time-space constraints, there may be a regular trade-off between frequency and duration. On the other hand, out-of-home social-recreational activity is a less urgent/impulsive activity and depends far more on an individual's day-to-day time-space constraints than his/her subjective characteristics. If the situation on the given day is not feasible for him/her to undertake the out-of-home social recreational activity, he/she is more likely to re-schedule the activity. The study results also show that land use configuration and perceived accessibilities influence individuals' discretionary activity participation.
