Background: Dementia presents significant challenges for informal caregivers. A gap remains in technology-driven personalized support tailored to caregivers' needs. Objective: To develop a theory-driven, multi-component mobile application specifically designed for caregivers of individuals with dementia and test its usability among end users. Methods: We developed "CareBuddy," a mobile care ecosystem based on the Stress Process Model and user-centered design. The app includes personalized assessments and tailored solutions, an AI-driven chatbot, GPS-based location monitoring, peer support, a helpline, telemedicine, healthcare provider integration and caregiver self-care resources. Development was informed by interviews with caregivers and stakeholders, followed by two-phase pilot testing to assess usability and acceptability involving 18 and 10 participants respectively. Results: In phase 1, the mean system usability scores (SUS) increased from 65.4 (S.D. 11.8) in round 1 to 73.8 (S.D. 15.9) in round 3, exceeding the benchmark SUS of 68. In phase 2, caregivers rated the app highly with mHealth app usability questionnaire (MAUQ) overall total mean score of 95.4 (SD 8.5). The domains of ease of use (mean 24.1; SD 2.9), user interface and satisfaction (mean 40.3; SD 3.4), and usefulness (mean 31; SD 3.9) received high MAUQ ratings. Participants valued the content focused on dementia management and caregiver well-being. Caregivers appreciated the interactive features -social networking portal, service directory, and conversational large language model. Feedback highlighted areas for improvement, including reducing textual overload and addressing navigational challenges. Conclusions: CareBuddy offers a multifaceted digital solution for dementia caregivers, with high usability and satisfaction. An ongoing trial is evaluating the app’s effectiveness in improving caregiver outcomes.

Background: Adolescents require comprehensive sexual and reproductive health (SRH) education to successfully transition from puberty into adulthood. However, they often experience barriers and challenges while trying to promote their SRH or access SRH services. Such challenges are amplified among youth from migrant backgrounds, who may further be constrained by societal stigmas and cultural taboos regarding SRH. Mobile health interventions have the potential to provide culturally relevant, accessible, and evidence-based SRH educational resources; however, few SRH mobile apps in Canada are co-designed with immigrant youth or meaningfully integrate their voices and lived experiences. Objective: We aimed to co-design a culturally relevant and evidence-based mobile app with immigrant adolescents to provide accurate SRH resources. In this paper, we present the findings of the #usability testing of our SRH mobile app—MyPeer. Methods: Throughout our study, we used a community-based participatory research approach and implemented the principles of human-centered design to co-design our mobile app. For our #usability study, we recruited immigrant adolescents and interest holders working with the target population. Adolescents participated in moderated focus group discussions (FGDs) and interest holders evaluated the app’s quality using the standardized Mobile App Rating Scale (rating components on a scale of 1-5). All FGDs were audio-recorded and later analyzed to implement changes in the app. Mobile App Rating Scale (MARS) scores and responses were analyzed descriptively to evaluate the app’s engagement, functionality, aesthetics, quality of information, and subjective app quality. Results: Overall, 25 adolescents and 17 interest holders participated in this #usability study. We analyzed the findings from the FGDs and categorized them into four categories: (1) navigation and interface, (2) SRH information quality and learning, (3) technical performance, and (4) accessibility and multimedia #usability. Adolescents found the app visually appealing and the interface easy to navigate. They appreciated interactive features, such as quizzes, and the presentation of information through various media (eg, videos and infographics). However, they also identified technical issues, such as map glitches and navigation inconsistencies, and requested deeper content on SRH topics. The data from the MARS checklist completed by interest holders were analyzed descriptively. The app received the highest scores in the domains of functionality, with mean scores of 4.3 (performance and navigation); engagement, with mean scores of 3.7 (interest); and aesthetics, with mean scores of 4.1 (graphics) and 3.9 (visual appeal). The lowest rated items were customization, with a mean score of 2.5, and interactivity, with a mean score of 3.1. Conclusions: Our app—MyPeer—has promising #usability and appeal for adolescents looking for SRH information. Incorporating feedback from youth and content experts helped identify both technical refinements and content requirements. Our findings support the app’s potential as a scalable, youth-centered SRH digital tool and emphasize the value of participatory design in youth digital interventions.

Background: Unhealthy food and beverage marketing influences children’s attitudes, preferences, and behaviours toward food. Most research studies on children’s exposure to food marketing focus on single settings, media, or marketing channels, precluding cumulative estimates of food marketing exposure across children’s daily lives. Therefore, there is a need for tools to measure food marketing across settings. Objective: This study aimed to test the #feasibility of a mobile application to assess food marketing observed by youth aged 13–17 years across settings in their daily life in Newfoundland and Labrador. Methods: Using a digital app, FoodMATS-Youth, 23 participants photographed food marketing they saw over three days. Each participant completed a feedback survey on #usability and acceptability of the digital app assessed through a 5-score rating of #feasibility outcomes. They also took part in focus groups, sharing their experiences with the app, and this data was thematically analyzed. Descriptive analyses of app-derived #feasibility metrics were also conducted. Results: The app had high #usability and acceptability based on the #feasibility outcomes, app-derived #feasibility metrics and focus group responses. For #feasibility outcomes, app navigation had the highest rating at 4.7, similar to ease of use and app responsiveness at 4.48; convenience was the lowest rated outcome at 4.0. App-derived #feasibility metrics like user compliance, response, and app completion rates were also high at 92%, 85.2% and 92%, respectively. A total of 146 photos of food marketing were submitted by participants through the app. Focus groups showed great participant satisfaction with the app’s interface and functionality. Conclusions: This study found that the FoodMATS-Youth mobile application is highly feasible for monitoring food marketing exposures across multiple settings (e.g. social media, grocery stores) and was well-received by our participants. The FoodMATS-Youth has the potential to efficiently improve food marketing research in Canada and internationally and generate data that can inform comprehensive food marketing policies.

Background: Patients with psoriasis and atopic dermatitis are at increased risk of several vaccine-preventable diseases. Despite this increased susceptibility to infections, vaccination uptake in adults with psoriasis and atopic dermatitis, especially if treated with biologics and other systemic immunomodulators, is insufficient. As mobile health technologies may support behavior change, a mobile app called DermatoVax was developed to raise awareness of immunization in adult patients with psoriasis and atopic dermatitis. Objective: This paper aims to describe the processes of development of the DermatoVax app and its initial evaluation in terms of technical verification and physicians’ quality rating. Methods: The app was conceived in a user-centered fashion. Its core component was the vaccine checker, which allows the app to produce a sharable list of recommended vaccines, immunization timings, and eventual precautions from a short set of input data. App prototypes were extensively piloted, and feedback from potential end users was obtained to refine the app content. The readability of the textual narratives was measured using the Italian-specific Gulpease index, which ranges from 0 to 100, where 100 indicates the best readability. The quality of the final version was evaluated by 46 medical doctors (n=29, 63% dermatologists and n=17, 37% public health physicians) using a validated Italian user version of the Mobile App Rating Scale (uMARS). Results: Iterative steps during the app development process allowed us to increase its user-friendliness and comprehensibility. Proper functioning of the checker was confirmed through the correct and complete generation of recommended vaccine lists for 50 mock patients with psoriasis and atopic dermatitis. An overall Gulpease index of 41.0 was observed for the final textual narratives, suggesting acceptable readability properties for patients with a high school diploma. Of a maximum of 5 points, the average uMARS score was 4.22 (SD 0.49). Ratings provided by dermatologists (mean 4.28, SD 0.48) were similar (P=.33) to those provided by public health physicians (mean 4.12, SD 0.51). However, the mean uMARS scores for the quality dimensions of aesthetics (3.88, SD 0.78) and engagement (3.89, SD 0.68) were lower than those for information (4.64, SD 0.42) and functionality (4.47, SD 0.46), suggesting margins for improvement. The app’s perceived impact was notably high, with over 80% of physicians agreeing that its use would significantly improve patient awareness (39/46, 85%) and knowledge (41/46, 89%) of vaccination, leading to increased vaccination uptake (37/46, 80%). Conclusions: DermatoVax is a promising tool to raise awareness of immunization in adult patients with psoriasis and atopic dermatitis. Further assessment of the app, such as its effectiveness in increasing vaccination uptake, is warranted.

Background: Migraines are a significant health concern affecting millions of individuals, often requiring habitual tracking of potential triggers to mitigate or predict episodes. Digital health tools such as mobile apps offer a scalable solution for personalized tracking and pattern recognition. Migraine Insight is one such app that facilitates daily logging to quantitatively assess individualized patterns of events preceding migraine onset. However, while various triggers have been reported in migraine literature, there is limited large-scale electronic user-driven data on the frequency and relative impact of specific triggers. Objective: This study aims to address this gap by analyzing user-reported data from Migraine Insight to identify the most frequently reported triggers and evaluate their potential associations with migraine onset. Methods: Food-associated migraine triggers were identified by performing a noninterventional, retrospective analysis of self-reported data obtained via the Migraine Insight app. A collaboration was made with the representatives of the Migraine Insight app to extrapolate the data needed for the study. A preliminary keyword list was assessed from a raw data set of 2605 data entry values, extracted from a 30-day period of September 19 to October 18, 2021, to identify high ranking self-reported events, classified by dietary habits, environmental conditions, body physiology, and medications. The variables examined included the following: dietary items, environmental conditions, body physiology, and electronics. Food items were combined into similar groups, considering variable spelling and descriptions of self-reported events. The association of migraine onset after consumption of top 5 dietary products was evaluated to establish the frequency of migraine episodes for all users who reported the items. Results: Collectively, food (n=353) and beverage (n=252) totaled the highest reported entries, with chocolate, wine, tea, coffee, and cheese as the highest ranked foods for prevalence of reporting across all users and for frequency of migraine onset for users who consumed the items within 48 hours. The 4 highest nonfood entries were altered sleep patterns (n=245), stress or anxiety (n=199), rain or storm conditions (n=192), and bright light or brightness (n=191). Statistical analysis showed that chocolate was the only food trigger significantly associated with migraines (P=.003 vs 50%; P=.04 vs average). Consumption of tea approached significance (P=.051), while consumption of coffee, cheese, and wine were not significant. These findings suggest that chocolate is the most consistent dietary trigger. Conclusions: High-risk foods, environmental conditions, stress, and lighting with highest prevalence reporting have previously been reported in medical literature, implicating that a migraine tracking app is a valid alternative to paper-based diaries.
