Extending the theory of planned behaviour: testing the effects of authentic perception and environmental concerns on the slow-tourist decision-making process

Despite the importance of slow tourism, studies on slow tourists' decision-making processes are rare. The current study extends the theory of planned behaviour (TPB) by including authentic perception (AP) and environmental concerns (ECs) to explain the formation of behavioural intentions. The study also contributes by comparing its extended model with the original TPB and identifying salient belief items through a focus group and literature review. The results of a structural equation analysis revealed that the data fitted the extended model well and that the inclusion of the critical new constructs in a slow-tourism context significantly enhanced the prediction of behaviour intentions. The results also indicated that attitude, subjective norms, perceived behaviour control, and AP significantly contributed to forming the intention to participate in slow tourism. However, the influence from ECs to behavioural intentions was demonstrated to be insignificant. This study advances our understanding of tourists' decision-making processes in that these slow tourists are more likely to choose an authentic, rather than environmental, destination.
