“…The Simplified SUS is an example of adapting standard human factors and human-computer interaction methods for work with new populations, retaining the strengths of the original method while accommodating the needs of the population. In the arena of patient ergonomics (Holden & Valdez, 2018Holden, Cornet, et al, 2020;Valdez et al, 2015), we have previously argued for this kind of theoretical and methodological adaptation of general methods, given the unique characteristics of patients and their work systems (Holden & Mickelson, 2013;Holden et al, 2015Holden et al, , 2018Novak et al, 2016). We have also argued that within patient ergonomics, vulnerable populations including those who are cognitively impaired or have low literacy, are rarely the targets of studies, or may not enroll in studies with broad inclusion criteria (Holden, Cornet et al, 2020;Holden, Toscos, et al, 2020).…”
