Abstract: “The purposes of this research were to measure and compare the effects of pollution news on audiences' attitudes toward tourism in Thailand. One hundred and fifteen foreign students were selected to determine whether their attitudes were changed after viewing the news. Statistical instruments such as mean, standard deviation, and t-test with the significant level at 0.05 were selected to complete the process of data analysis of pretest and posttest. The results found that after viewing the news, the level of audience attitudes and intention significantly changed from positive country image to negative country image. However, gender was not a significant factor. This study found that male and female in both pretest and posttest were not significantly different in overall perspective, except for some issues. In pretest, female had significantly less positive country image of Thailand on environment issue than those of male. In posttest, female had more significantly negative country image”
