Psychometric evaluation of acceptability, appropriateness, and feasibility measures for a students’ online health appointment system in a university hospital in Ghana

We found promising psychometric properties of the adapted Acceptability, Appropriateness, and Feasibility measures, including high internal consistency, good model fit, and strong convergent validity. However, significant overlap between acceptability and appropriateness necessitates that future studies refine these constructs conceptually and empirically, thereby improving their discriminant validity. Importantly, these validated measures provide a valuable framework for guiding evaluations of digital health implementation in similar settings.
