A multiple item tourism impact attitude scale (TIAS) was developed in
response to the need for standardized measurement of resident attitude
s toward tourism development. The scale development process and testin
g of the scale is described in this paper. The tourism impact literatu
re cites a number of key independent variables that influence attitude
s toward tourism. Using the TIAS, a multiple regression model was used
to test the effects of these independent variables on resident attitu
des toward tourism development in the Columbia River Gorge region of O
regon and Washington, USA. Implications for tourism development and pl
anning are described.
