While studies on the damaging effects of PM2.5 air pollution are abundant, studies seeking to understand the factors that influence human behaviors for the avoidance of exposure to PM2.5 are lacking. Theory of Planned Behavior (TPB) can be used to investigate the effects of Attitudes (AT), Subjective Norms (SN), and Perceived Behavioral Controls (PBC) in the Behavioral Intentions (BI) of parents with young children against exposure to PM2.5. Questionnaires, based on the TPB used to predict BI, were distributed to 610 parents in Taipei City and New Taipei City. Our results revealed that the AT of both groups had a significant positive predictive effect on their PBC and BI. While the SN of the Taipei group affected BI directly, there was no significant effect on the BI from the SN of the New Taipei group. Using path analysis, Taipei City and New Taipei City groups had different BI paths: All five hypotheses are statistically significant and form four paths in the Taipei City group. While only four hypotheses in the New Taipei City group formed three paths and no path for SN-BI. Both groups formed behaviors that were based on the SN/PBC around them, which ultimately contributed to the BI of their protective behaviors.
虽然已有大量研究探讨了 PM2.5 空气污染的危害，但缺乏研究来了解影响人类避免接触 PM2.5 的行为的因素。计划行为理论（TPB）可用于研究父母对子女避免接触 PM2.5 的态度（AT）、主观规范（SN）和感知行为控制（PBC）对行为意图（BI）的影响。本研究基于 TPB 设计了问卷，调查了台北市和新北市 610 名家长的 BI。结果表明，两组的 AT 对 PBC 和 BI 有显著的正向预测作用。台北组的 SN 直接影响 BI，而新北组的 SN 对 BI 没有显著影响。路径分析表明，台北市和新北市两组的 BI 路径不同：台北市组的五个假设均具有统计学意义，形成了四条路径；新北市组只有四个假设形成了三条路径，SN-BI 无路径。两组都形成了基于周围 SN/PBC 的行为，这最终促成了他们的保护行为的 BI。
