The current study offers insight into the role of motivation and constraints on behavioural intentions prior to a mega event. The Psychological Continuum Model framework was used to integrate motivation and leisure constraints theory to examine attraction toward the 2008 Olympic Games. Semi-structured interviews (N = 47) and a questionnaire (N = 235) distributed in Australia and the United States were used to identify and measure three motivational themes: Cultural Learning, Cultural Experience, and Olympic Event Interest and three perceived constraints: Structural, Interpersonal and Intrapersonal. Structural Equation Modelling revealed motives were positively related to behavioural intentions while constraints were negatively related. Analysis further revealed the interaction between motives and perceived constraints led to two different forms of behavioural intentions; intentions to travel and attend the event vs. stay home to watch the event on TV. Policy and marketing implications are discussed that illustrate the benefits of understanding both motives and perceived constraints for tourism travel.
