Patient-centered approaches for teaching diabetes mellitus (DM) survival skills are essential. Furthermore, in the peri-COVID era, interventions also need to be amenable to remote care delivery. User-Centered design (UCD) including usability testing is a key strategy to optimize adoption and engagement of interventions. We developed a Diabetes Survival Skills Toolkit (website, paper guide, and a physical Kit with simulation supplies) using UCD (&gt; 50 sessions), followed by administration of system usability surveys (SUS) (scored as unacceptable, acceptable, or excellent) and, in a subset, additional skills testing. Skills testing included simulated blood glucose checks and insulin administration, conducted by 2 trained observers. Forty-three participants with no prior history of DM were recruited between 01/2021-07/2022 to independently learn survival skills using different Toolkit components [website only (N=11), Kit + paper guide (N=28), and Kit + website (N=4)]. Purposive sampling for age and highest education level resulted in 33% being ≥ 65 years and 35% having &lt; 4-year degree. Overall, SUS scores were deemed excellent (N=15/43 [35%]) or acceptable (N=20/43 [47%]). Unacceptable scores were noted in 8/43 (19%) [4 website only (all &gt; 4-year degree) and 4 Kit + paper guide (3 of 4 &gt; 65 years, all &lt; 4-year degree)]. Use of the website alone resulted in a higher rate of unacceptable SUS scores (37%) compared to use of the Kit with either the paper guide or website (13%). SUS-score category was not associated with age (82% acceptable/excellent among &lt;45 years, 86% among 45-64 years, and 79% among &gt;=65 years; Fishers’ p=1.00) nor highest education level (80% acceptable/excellent among &lt;4-year degree and 82% among &gt;=4-year degree; Fisher’s p=0.69). Participants who completed skills testing (N= 28 Kit + paper guide, 4 Kit + website), regardless of their SUS score, all correctly demonstrated the ability to inject insulin with simulation supplies. However, 4/32 (13%) (all SUS scores acceptable/excellent) were unable to navigate all steps independently and 9/32 (28%) (2 SUS unacceptable) did not use the recommended instructional pathway. All 4 participants (3 with &gt; age 65 and &lt; 4-year degree) who completed skills testing but had unacceptable SUS scores still correctly demonstrated the ability to measure blood glucose and inject insulin. In conclusion, a Survival Skills Toolkit, resulted in excellent rates of successful survival skills performance when tested with laypersons of diverse ages and education levels. Subjective usability (SUS scores) did differ among users of different Toolkit components; however, they did not align with actual skill performance. Design preferences and usability tests as well as subsequent skills testing are critical to optimally design tools for diabetes survival skills training.
