“…We believe the value of implementing a user-centered development approach carried through to the engagement outcomes presented above, with the results indicating positive engagement overall. During our development work [15], we were able to understand aspects of the user experience that were important to our target users. Consequently, many of the factors that appeared to facilitate positive engagement outcomes were related to areas where attention was focused during our user-centered development-weekly structured program delivery; relevant content; accessibility; and positively-framed easy to understand communication.…”

“…Participants who accepted the invitation were engaged in 20 to 30-minute semi-structured individual interviews. The semi-structured interview guide (S2 Appendix) had previously been tested during our user-centered development work [15], and was revised for this study with pilot testing through discussion (JD, SMSI) prior to the interviews. Phone interviews were conducted by the same facilitator (JD), and audio recorded with participant's written and verbal consent.…”

“…Effective engagement is said to begin with an iterative user-centered process employed during intervention development stages [6,7]. Thus, four phases of iterative user-centered development, involving adults with T2D, were conducted for the T2Diet study, details were published elsewhere [15]. Furthermore, the study protocol detailing the intervention was published elsewhere [16].…”

“…It is important to highlight, that users of an intervention are the direct line to improving the user experience to foster better engagement outcomes [47,48]. Thus, employing a user-centered approach to intervention development [15] is recommended to improve engagement outcomes, as demonstrated by this study and previous web-based dietary interventions in T2D [41]. To further improve participant engagement and experience, findings of this study suggest exploring broader content (addressing costs/budgets and accommodating different household dietary needs), and the addition of a smartphone app may further benefit participants with T2D.…”

Background Improved understanding of participant engagement in web-based dietary interventions is needed. Engagement is a complex construct that may be best explored through mixed methods to gain comprehensive insight. To our knowledge, no web-based dietary intervention in people with type 2 diabetes (T2D) has previously used a mixed methods approach. The aim of this study was to explore factors that may contribute to effective engagement in a web-based dietary program for people with T2D. Methods This study employed a mixed methods intervention design, with a convergent design embedded for post-intervention evaluation. The convergent design collected and analyzed quantitative and qualitative data independent of each other, with the two datasets merged/compared during results/interpretation. Quantitative data collected from intervention group participants (n = 40) were self-administered questionnaires and usage data with average values summarized. Qualitative data were participant semi-structured interviews (n = 15) incorporating a deductive-inductive thematic analysis approach. Results The results from the quantitative and qualitative data indicated positive overall engagement with the web-based dietary program. Factors that contributed to effective engagement were sustained frequency and intensity of engagement; structured weekly program delivery; participants affective engagement prior to and during the intervention, with positive affective states enhancing cognitive and behavioral engagement; and participants experience of value and reward. In addition, the user-centered development process employed prior to intervention delivery played an important role in facilitating positive engagement outcomes. Conclusion This study yielded novel findings by integrating qualitative and quantitative data to explore engagement with a web-based dietary program involving people with T2D. Effective engagement occurred in this intervention through a combination of factors related to usage and participants’ affective, cognitive and behavioral states. The engagement outcomes that emerged will be useful to current and future researchers using digital technologies to deliver lifestyle interventions for T2D or other chronic health conditions.

“…Technology has the potential to address these limitations, by empowering people with heart failure to better manage their health, and to optimize communication with their clinicians when and if needed. Further, current approaches for designing technology interventions have typically failed to include patients and clinicians in the product design ( 14 ), which leads to lower levels of acceptance, dissatisfaction, stress and non-adherence ( 15 – 17 ).…”

BackgroundSmart home systems could enhance clinical and self-management of chronic heart failure by supporting health monitoring and remote support, but evidence to guide the design of smart home system functionalities is lacking.ObjectiveTo identify consensus-based recommendations for functions of a smart home system that could augment clinical and self-management for people living with chronic heart failure in the community.MethodsHealthcare professionals caring for people living with chronic heart failure participated in a two-round modified Delphi survey and a consensus workshop. Thirty survey items spanning eight chronic health failure categories were derived from international guidelines for the management of heart failure. In survey Round 1, participants rated the importance of all items using a 9-point Liket scale and suggested new functions to support people with chronic heart failure in their homes using a smart home system. The Likert scale scores ranged from 0 (not important) to 9 (very important) and scores were categorized into three groups: 1–3 = not important, 4–6 = important, and 7–9 = very important. Consensus agreement was defined a priori as ≥70% of respondents rating a score of ≥7 and ≤ 15% rating a score ≤ 3. In survey Round 2, panel members re-rated items where consensus was not reached, and rated the new items proposed in earlier round. Panel members were invited to an online consensus workshop to discuss items that had not reached consensus after Round 2 and agree on a set of recommendations for a smart home system.ResultsIn Round 1, 15 experts agreed 24/30 items were “very important”, and suggested six new items. In Round 2, experts agreed 2/6 original items and 6/6 new items were “very important”. During the consensus workshop, experts endorsed 2/4 remaining items. Finally, the expert panel recommended 34 items as “very important” for a smart home system including, healthy eating, body weight and fluid intake, physical activity and sedentary behavior, heart failure symptoms, tobacco cessation and alcohol reduction, medication adherence, physiological monitoring, interaction with healthcare professionals, and mental health among others.ConclusionA panel of healthcare professional experts recommended 34-item core functions in smart home systems designed to support people with chronic heart failure for self-management and clinical support. Results of this study will help researchers to co-design and protyping solutions with consumers and healthcare providers to achieve these core functions to improve self-management and clinical outcomes in people with chronic heart failure.
