Usability evaluation of a physical activity smartphone application in wheelchair users with spinal cord injury

This dataset contains raw quantitative data collected to evaluate system usability, e-loyalty, user experience and intentions to use a physical activity App (MvBii) that was evaluated within this project. Participants completed the following questionnaires to evaluate system usability, user experience and intentions to use the App. Each item used a 7-point Likert scale ranging from “Strongly disagree” to “Strongly agree” to evaluate the following constructs: System Usability Scale (SUS): a 10-item questionnaire to provide a global subjective opinion of usability (Brooke, 1996). E-loyalty: assessed using three items that measured intention to use the App again in the future (Crutzen et al., 2011). User Experience: assessed using four items that evaluated perceived efficiency, effectiveness, trustworthiness, enjoyment and active trust (Crutzen et al., 2011). Intention to use the App: a single item derived from socio-cognitive models (e.g. Theory of Planned Behaviour and I-Change Model) to reflect the most proximal determinant of behaviour (e.g. adoption of an intervention) (K. L. Cheung et al., 2018).
