The variation of self-determined travel facilitation across different challenge levels is examined through a quasi-experimental design and analyzed with a new test of moderated mediation based on Hayes¡¯ (2015a) model. The results indicate that for PwMC with significant travel challenge levels, the tourism industry should prioritize the cultivation of intrinsic travel motivations and perceived travel competence satisfaction over less-autonomous motivation dimensions and satisfaction of alternative psychological needs. Such cross-context exploration extends self-determination theory with a new moderator of challenge levels. The adopted new analysis of moderated mediations is competitive regarding accuracy, efficiency, and robustness for less-controlled, real-world tourism experiments. Results can also guide the customization of motivational programs for different PwMC to maximize the effectiveness of psychological empowerment for travel %K self-determination theory %K disabilities %K travel challenges %K moderated mediation analysis %K quasi-experimental design %U https://journals.sagepub.com/doi/full/10.1177/0047287517741004
