BACKGROUND Childhood obesity is a serious public health issue among minority youth in the United States. Technology-enhanced approaches can be effective for promoting healthy behavior change. OBJECTIVE The purpose of this study was to test the usability of prototypes of a Web-based interactive tool promoting healthy dietary behaviors to reduce childhood obesity risk in urban minority youth. The Web-based tool comprised a manga-style comic with interactive features (eg, sound effects, clickable pop-ups), tailored messaging, and goal setting, and was optimized for use on tablet devices. METHODS Latino and black/African American children ages 9 to 13 years were recruited to participate in two rounds of usability testing. A modified think-aloud method was utilized. Self-reported surveys and field notes were collected. Audio recordings and field notes from usability testing sessions were systematically reviewed by extracting and coding user feedback as either positive comments or usability or negative issues. The quantitative data from self-reported questionnaires were analyzed using descriptive statistics. RESULTS Twelve children (four female; eight black/African American) with a mean age of 10.92 (SD 1.16) years participated. Testing highlighted overall positive experiences with the Web-based interactive tool, especially related to storyline, sound effects, and color schemes. Specific usability issues were classified into six themes: appearance, content, special effects, storyline, terminology, and navigation. Changes to the Web-based tool after round 1 included adding a navigation guide, making clickable icons more visible, improving graphic designs, and fixing programming errors. In round 2 of testing (after modifications to the Web-based tool were incorporated), many of the usability issues that were identified in round 1 did not emerge. CONCLUSIONS Results of testing will inform further development and finalization of the tool, which will be tested using a two-group pilot randomized study, with the goal of reducing childhood obesity risk in minority, low-income youth.

BACKGROUND In the United States, childhood obesity prevalence is highest among preadolescents and adolescents. Research has increasingly highlighted the role of parenting, parental modeling and feeding practices, and the home environment in behavioral interventions for childhood obesity. OBJECTIVE As part of the development of a technology-enhanced intervention to promote healthy eating among urban minority preadolescents, research was concurrently conducted to develop a parent-focused health promotion tool to support positive feeding behaviors and the home food environment. METHODS Parents (n=25; 96% female; mean age=41 years; 60% Hispanic/Latino, 40% Black/African-American) were recruited from a child-focused community-based organization in New York City. Formative research (focus groups and parent-child dyad interviews) was conducted to identify barriers/facilitators to healthy feeding behaviors and characterize technology use (Summer 2016). Findings informed the design of a web-based health promotion tool, which was iteratively developed and assessed utilizing user-centered approaches to: confirm/finalize content (Fall 2016), assess the website wireframe (Winter 2016), and conduct usability testing (Spring-Summer 2017). Session notes and audio-recordings were reviewed throughout development to design and improve prototypes. RESULTS From formative research, parents preferred reading/looking up health-related information on larger laptop/tablet screens, but preferred smartphones when reading “on-the-go.” Suggestions for an online health tool included quick/easy/low-cost recipes, healthy tips for health feeding and involving their children around healthy dietary-related behaviors, clear tool navigation, and using pictures/visuals. When finalizing the tool wireframe and content, parents preferred a variety of motivational healthy feeding tips that encouraged positive interaction with their child, local family-oriented community events, and a simple, colorful layout with minimal clicking to access links. During usability testing, parents responded positively to the content (healthy feeding tips, recipes, coupon, and free community event) and clean layout, especially the use of bright color schemes and easy navigation. Suggestions included incorporating more fruit/vegetable images and directed action words (“click here”) to draw attention to coupon/community event links. CONCLUSIONS Formative research and user-centered approaches with parents of at-risk preadolescents resulted in a web-based, mobile-friendly health promotion tool. It will be tested as part of a larger technology-enhanced intervention using a two-group pilot randomized study, with the aim of reducing childhood obesity risk.

BACKGROUND Childhood obesity is a public health crisis, particularly in low-income, minority populations in the United States. Innovative and technology-enhanced interventions may be an engaging approach to reach at-risk youth and their parents to improve dietary behaviors and feeding practices. However, such tools are limited, especially ones that are theory-based; co-developed with user-centered approaches; tailored to low-income, minority preadolescents; and include parent-focused content. OBJECTIVE The objectives of this study include assessing the feasibility and acceptability and exploring the potential impact of the Intervention INC (Interactive Nutrition Comics for urban, minority preadolescents) Web-based tool, which is focused on decreasing childhood obesity risk in black/African American and Latino children aged 9 to 12 years. METHODS Intervention INC is underpinned by the narrative transportation theory, social cognitive theory, and health belief model, and it was co-developed by children and parents from the intended population. The child component consists of a 6-chapter interactive nutrition comic optimized for use on tablet devices, a goal-setting and self-assessment feature, and weekly text/email messages and reminders. The parental component consists of 6 Web-based newsletters, access to the child comic, and weekly text/email messages and reminders. The tool was evaluated using a pilot, single-blind, 2-group randomized controlled study design. Child-parent dyads were randomized to either the experimental or comparison group and assigned to a targeted behavior (increase fruit/vegetable or water intake) based on initial screening questions. Data were collected at 4 time points: baseline (T1), intervention midpoint (T2), intervention endpoint (T3), and 3 months postintervention (T4). Primary measures comprise usage, usability, and feasibility of the Web-based tool. Secondary measures comprise dietary knowledge, preferences, and intake and anthropometric measures (for child) and feeding practices and home food environment (for parent). RESULTS Study enrollment was completed in November 2017. A total of 89 child-parent dyads were randomized to either the experimental (n=44) or comparison (n=45) group. Data analysis is currently being conducted. CONCLUSIONS This study aims to implement and assess an innovative approach to deliver health messages and resources to at-risk minority preadolescents and their parents. If found to be acceptable, engaging, feasible, and a potential approach to improve dietary behaviors, a full-fledged randomized controlled trial will be conducted to assess its efficacy and potential impact.

BACKGROUND Familial hypercholesterolemia (FH), a prevalent genetic disorder, remains significantly underdiagnosed in the United States (US). Cascade testing, whereby diagnosed FH probands can contact their family members and inform them of their risk for FH, has low uptake in the US. Digital tools are needed to facilitate communication between FH probands and their family members and promote sharing of FH-related risk information. OBJECTIVE In this report we describe the creation and evaluation of a web-based tool designed to enhance familial communication and promote cascade testing for FH. METHODS A hybrid type 1 implementation science framework and a user-centered design process were used to develop an interactive web-based tool — ‘FH Family Share,’ that enables FH probands to communicate information about their FH diagnosis with at risk relatives. Probands can also use FH Family Share to draw a family pedigree, learn more about FH through education modules and access curated knowledge resources. Research-Based Web Design and Usability Guidelines from the US Department of Health and Human Services’ (DHHS) were taken into account during the design and development of the tool. The initial prototype underwent a ‘cognitive walkthrough’ conducted by usability experts, which was followed by usability testing with key stakeholders including genetic counselors (GCs) and FH patients. Participants navigated the prototype and employed the ‘Think Aloud’ technique to share feedback that was used to refine features of FH Family Share. Usability testing was informed by the International Organization for Standardization (ISO) Quality Standards for Usability. RESULTS Six key themes emerged from the cognitive walkthrough including: Design, Format, Navigation, Terminology, Instructions and Learnability. Expert feedback from the cognitive walkthrough resulted in a rebuild of the web-tool to align it with institutional standards. Usability testing with GCs and FH patients provided key insights on user experience, satisfaction and interface design and highlighted specific modifications that were made to iteratively refine the features of FH Family Share and facilitate its clinical integration. GCs and FH patients suggested inclusion of the following features in the web-tool: 1) Templated ‘letter to family member’ email; 2) Education modules; and 3) Knowledge resources. Surveys revealed that 66.7% of GCs found information within the FH Family Share tool ‘very easy to find’ and 55.6% found information ‘very easy to understand,’ while 55.6% of patients found information ‘very easy to find’ within the website and 77.8% of patients found information ‘very easy to understand.’ All GCs and patients found FH Family Share to be a resource worth returning to. CONCLUSIONS We describe the creation of FH Family Share, a web-based tool to promote cascade testing for FH by facilitating communication between probands and their relatives. Once informed, at-risk family members have the option to seek testing and treatment for FH.
