The annual Southeast Asian haze pollution raises public health concerns in this region. Based on a modified extended parallel process model, this study examines efficacy (self-efficacy and response efficacy) and perceived threat (susceptibility and severity) and incorporates new constructs of media trust and affective attitude. Results from a Web survey of 410 undergraduate students in Singapore show that response efficacy to seek haze-related information mediates the association between perceived self-efficacy and intention to take protective measures during haze. Moreover, self-efficacy is negatively associated with affective attitude (e.g., fear and worry) toward haze-related health problems. Next, perceived severity and perceived susceptibility are positively associated with response efficacy and affective attitude. Affective attitude toward haze is a stronger predictor than response efficacy for behavioral intention. Finally, trust in new media is positively associated with young Singaporeans' affective attitude, which positively affects their behavioral intention to take protective measures.
每年的东南亚雾霾污染引发了该地区对公众健康的担忧。基于一个改进的扩展平行过程模型，本研究考察了效能（自我效能和反应效能）和感知威胁（易感性和严重性），并纳入了媒体信任和情感态度的新构念。对新加坡410名本科生进行的网络调查结果显示，寻求雾霾相关信息的反应效能在感知自我效能与雾霾期间采取保护措施的意图之间起中介作用。此外，自我效能与对雾霾相关健康问题的情感态度（如恐惧和担忧）呈负相关。其次，感知严重性和感知易感性与反应效能和情感态度呈正相关。对雾霾的情感态度比反应效能对行为意图的预测力更强。最后，对新媒体的信任与新加坡年轻人的情感态度呈正相关，而情感态度又积极影响他们采取保护措施的行为意图。
