Specification of the regression models was based on the social exchange theory (Ap 1992) and findings from previous studies. To reduce the number of dependent variables of the regression models we have first conducted a Principal Component Analysis (PCA) with varimax rotation on statements regarding residents’ attitudes toward tourism policy. For the same reason, and in order to obtain uncorrelated variables, we have also conducted a PCA on statements related residents’ opinions towards the economic, environmental and sociocultural impacts of tourism.
