“…User-centric approaches, driven by user-centred evaluation to address the whole user experience in relation to the tasks and contexts [30,36], offer insights into how a user-centric STEM curriculum may look like. General phases of the user-centric approach basically entail: (1) specifying the context of use, (2) specifying the requirements or user goals, (3) creating design solutions, and (4) evaluating designs.…”

<p style='text-indent:20px;'>This commentary is an extension to the integrated S-T-E-M Quartet Instructional Framework that has been used to guide the design, implementation and evaluation of integrated STEM curriculum. In our discussion of the S-T-E-M Quartet, we have argued for the centrality of complex, persistent and extended problems to reflect the authenticity of real-world issues and hence, the need for integrated, as opposed to monodisciplinary, STEM education. Building upon this earlier work, we propose two additional variationsjsolution-centric and user-centric approachesjto the provision of integrated STEM curricular experiences to afford more opportunities that address the meta-knowledge and humanistic knowledge developments in 21<sup>st</sup> century learning. These variations to the S-T-E-M Quartet aims to expand the scope and utility of the framework in creating curriculum experiences for diverse profiles of learners, varied contextual conditions, and broad STEM education goals. Collectively, these three approachesjproblem-centric, solution-centric, and user-centricjcan afford more holistic outcomes of STEM education.</p>

“…The interviews were open-ended and organized to cover predesignated core topics. An interview guide was developed and pilot-tested using the constructs of the Healthcare Service Utilization Model as reported elsewhere [ 26 , 27 ] and the Technology Acceptance Model [ 28 , 29 ] ( Multimedia Appendix 1 ). This open-ended approach ensured systematic coverage of specific areas of interest while allowing for unanticipated content to emerge.…”

mHealth-Based Health Promotion Intervention to Improve Use of Maternity Care Services Among Women in Rural Southwestern Uganda: Iterative Development Study

et al. 2021

Background Antenatal care (ANC) prevents perinatal morbidity and mortality, but use of these services in Uganda remains low and maternal mortality rates are among the highest in the world. There is growing evidence that mobile health (mHealth) approaches improve timely communication of health-related information and produce positive health behavior change as well as health outcomes. However, there are limited data to guide development of such interventions in settings where ANC attendance and uptake of skilled maternity care are low. Objective The aim of this study is to develop a novel patient-centered mHealth intervention to encourage and support women to use maternity care services in Mbarara district, southwestern Uganda. Methods Using an iterative development approach, we conducted formative stakeholder interviews with 30 women and 5 health care providers (HCPs) to identify preferred key ANC topics and characterize the preferred messaging intervention; developed content for SMS text messaging and audio messaging with the help of 4 medical experts based on the identified topics; designed an app prototype through partnership with an mHealth development company; and pilot-tested the prototype and sought user experiences and feedback to refine the intervention through 3 sets of iterative interviews, a focus group discussion, and 5 cognitive interviews. Qualitative data were coded and analyzed using NVivo (version 12.0; QSR International). Results Of the 75 women who completed interviews during the development of the prototype, 39 (52%) had at least a primary education and 75 (100%) had access to a mobile phone. The formative interviews identified 20 preferred perinatal health topics, ranging from native medicine use to comorbid disorders and danger signs during pregnancy. In all, 6 additional topics were identified by the interviewed HCPs, including birth preparedness, skilled delivery, male partner’s involvement, HCP interaction, immunization, and caring for the baby. Positive audio messaging and SMS text messaging content without authoritative tones was developed as characterized by the interviewed women. The postpilot iterative interviews and focus group discussion revealed a preference for customized messaging, reflecting an individual need to be included and connected. The women preferred short, concise, clear actionable messages that guided, supported, and motivated them to keep alert and seek professional help. Complementary weekly reminders to the women’s significant others were also preferred to encourage continuity or prompt the needed social support for care seeking. Conclusions We used an iterative approach with diffuse stakeholders to develop a patient-centered audio messaging and SMS text messaging app designed to communicate important targeted health-related information and support rural pregnant women in southwestern Uganda. Involving both HCPs and end users in developing and formulating the mHealth intervention allowed us to tailor the intervention characteristics to the women’s preferences. Future work will address the feasibility, acceptability, and effectiveness of this design approach.

“…The study took place from August 2015 to December 2018 (Figure 1) and was conducted in 3 phases. We worked with an app designer and developer to create the app using a user-centered design approach during each study phase [12]. The study design is consistent with recommendations on mHealth technology development and evaluation, including user experience design, development, and alpha and beta testing [13].…”

BACKGROUND Mobile device-based (mHealth) tools to help adolescents practice skills outside of cognitive behavioural therapy (CBT) sessions for treating an anxiety disorder may lead to greater treatment gains. OBJECTIVE To develop, design, and test the acceptability, learnability, heuristics, and usability of MindClimb, an mHealth app for adolescents with anxiety to use between CBT sessions to plan and complete exposure activities using skills (cognitive, relaxation, exposure practice, and reward) learned in treatment. METHODS This was a three-phase study from August 2015 to December 2018. In phase 1, the app was designed and developed in consultation with young people and CBT therapists to identify desired functions and content. Feedback was subjected to thematic analysis using a general inductive approach. In phase 2, two high-fidelity testing sessions took place using the Think Aloud approach (acceptability, learnability, usability) and 10 item System Usability Scale with 10 adolescent receiving CBT. The high fidelity MindClimb app was evaluated by 5 app developers based on Nielsen’s 10 usability heuristics and 5point Severity Ranking Scale. In phase 3, 8 adolescents and 3 therapists assessed the usability of MindClimb during CBT sessions by recording frequency of skills practice, use of MindClimb features, satisfaction with the app, and barriers and facilitators to app use during treatment. RESULTS Feedback from phase 1 consultations indicated that the app should be: 1) responsive to user needs and preferences, 2) easy to use and navigate, 3) relevant content to the practice of CBT for anxiety, and 4) aesthetically appealing. Using this feedback as a guide, a fully functional app prototype for usability testing and heuristic evaluation was developed. In phase 2 Think Aloud and usability data resulted in minor revisions to the app including refinement of exposure activities. The average system usability score was 77 in both testing cycles indicating acceptable usability. The heuristic evaluation by app developers identified only minor errors (e.g. increase loading speed of app content, score of 1 on the Severity Ranking Scale). In phase 3, adolescents considered app features for completing exposure and relaxation modestly helpful (6.2/10 [exposure feature] and 6.4/10 [relaxation]). Both adolescents (average score 11.3/15, SD 1.6) and therapists (average score 10.0/12, 2.6 SD) reported being satisfied with the app. CONCLUSIONS The user-centered approach to developing and testing MindClimb resulted in an mHealth app that can be used by adolescents during CBT for anxiety. Evaluation of the use of this app in a clinical practice setting demonstrated that adolescents and therapists generally felt it was helpful for CBT practice outside of therapy sessions. Implementation studies to optimize integration of technology in clinical care and examine the impact of the app + CBT on clinical care processes and patient outcomes are now necessary.
