This study aims to validate the underlying structures of integrated resort customers’ needs satisfaction. This work proposes a nine-item scale that captures three distinct dimensions, namely, autonomy, competence, and relatedness needs satisfaction, using a mixed method including qualitative and quantitative studies. The predictive validity of customers’ autonomy, competence, and relatedness needs satisfaction on hedonic and eudaimonic well-being examined in two different cultures: Asia and the United States. This study contributes to the tourism and hospitality research by providing evidence of customers’ needs satisfaction from integrated resort brand experience and its role in improving customers’ well-being using cross-cultural samples. Thus, the authors highlight the importance of tourism and hospitality brand experiences which are beneficial for individual life in terms of basic psychological needs satisfaction.
