ABSTRACT Drawing on protection motivation theory and resilience theory, this study develops a conceptual framework of perceived vulnerability, perceived threat severity, coping appraisal, psychological resilience and pro-environmental behavioural intention based on a sample of 1,079 tourists in Taiwan. The empirical findings indicated that both tourists’ perceived vulnerability and perceived threat severity were significantly related to their coping appraisal. Moreover, tourists’ coping appraisals were positively and significantly related to their psychological resilience, which positively and statistically impacted their pro-environmental behavioural intentions. Tourists’ coping appraisals and psychological resilience also played meditating roles in the proposed conceptual framework. These findings thus extend scientific knowledge by providing insights and implications for sustainable tourism that contribute to the literature.
