The purpose of this study is to identify the association between the awareness of fine dust problem of people who participate in leisure activities and planned behavioral theoretical factors. People who participate in leisure activities were selected as a population group and subjects were extracted by using two screening questions. This study used 300 sample questionnaires for analysis except for 17 unqualified and inadequate questionnaires among 317 questionnaires. SPSS 23 version program was used for collecting data and results were obtained by using correlation analysis and multiple regression analysis. Findings that tested the association between the awareness of fine dust problems and planned behavioral theoretical factors are presented as follows. First, threat perception of fine dust problems affected positively attitude(β=.518, p<.001) and the awareness of problem occurrence influenced negatively(β=-.273, p<.001). Second, this study demonstrated that the awareness of fine dust problems gave negative impacts on subjective norms(β=.512, p<.001). Third, the awareness of fine dust problems had positive effects on perceived control(β=.260, p<.001). Lastly, analysis of the awareness of fine dust problems dividing into indoor leisure activity and outdoor leisure activity found that both groups showed identical outcomes. In conclusion, fine dust problems affected attitude with the highest explanation power followed by subjective norms. Moreover, no difference was found in the effects of fine dust problems on people who participate in outdoor and indoor leisure activities and planned behavioral factors. Therefore, realistic solutions fit these characteristics need to be prepared.
