Collective protection motivation model (Fukada & Tozuka, 2001) expected that the behavioral intentions of collective coping toward environmental problems is determined by eight cognitive factors (severity, vulnerability, efficacy, cost, ability to act, responsibility, practician ratio, and norm). The purpose of this study was to explore these 8 factors empirically. One hundred and eighty four university students (92 men and 92 women) were asked to rate those cognitive factors and intentions, of 7 collective coping act for 4 environmental problems (harms from dioxin, water pollution, global warming, and electricity shortage). The results of multiple regression analyses showed that severity, vulnerability, efficacy, cost, ability to act, responsibility, and practician ratio influenced behavioral intentions of collective coping. On the other hand, no effects were found for norm. These results proved that determinants of collective protection motivation model were almost useful for predicting behavioral intentions of collective coping.
