dHealth Solution for Improving Parent Adherence to Behavioral Treatment for ADHD

This study aims to develop, refine and preliminarily test a novel and scalable digital health solution designed to address parent adherence barriers in daily life contexts and increase parent's sustained use of evidence-based parenting strategies.

The study includes the following 3 phases:

1. Discovery phase: During the Discovery phase, we will conduct 1-hour focus groups at school sites with parents (N=8) and school mental health providers (N=4), who are considered major stakeholders and potential users of the dHealth tool. The purpose of these groups is to obtain feedback and guidance on features and procedures in order to maximize the usability and feasibility of the dHealth tool. This design includes participants who have completed a parenting skills treatment (CLS) and thus would be better informed to comment on needs for the augmented treatment. Stakeholders will be queried about their preferences regarding the application layout, tools, content, and features (e.g., reminders, badges). Recorded focus group sessions will be transcribed and coded for themes related to usability and feasibility.
2. Design and Build phases: Feedback from the discovery phase will be incorporated into the design and build phases, during which time prototypes will be put through proof of concept testing with parents and school clinicians who had participated in the discovery phase. Qualitative data will be collected at 2 time points during the design and build phases. Quantitative data will be gathered using the System Usability Scale (SUS) for each component prototype (e.g., description of skill, video examples, interactive activities). A fully functioning application will be completed at the end of the build phase and ready for the test phase.
3. Test Phase: The test phase is a 2-month pilot open trial of the dHealth tool with parents. We will provide the dHealth tool to parents who participated in the prior phases (N=5) as well as a new sample of parents (N=12) who will test the tool with their children in conjunction with the parent's participation in BPT at their school (to test tool utility during the course of treatment). Parents will be advised to use the tool daily to record parenting strategy use and to access information/training as needed. Qualitative semi-structured interviews during and after the trial will assess reactions to the platform (usability, feasibility, acceptability) to inform refinements and identify barriers and facilitators relating to use. Primary outcomes focus on usage metrics with the tool (e.g., frequency of use, module and activity completion, time, repeat activity), reported daily parenting skills use on the tool, and measures of feasibility and acceptability. Application usage analytics will be collected by the mobile application, providing objective descriptives including how often and for how long individuals access the application and each component, as well as how users navigate through the application. This data will be analyzed for patterns associated with tool satisfaction ratings, feasibility, and acceptability ratings and reported skill utilization. Secondary outcomes of parent knowledge, motivation and confidence in using EBT skills; parenting practices, ADHD symptoms and functional outcomes will be assessed before and after tool usage.
4. Randomized Controlled Trial (RCT) Phase: The RCT phase is a 20-month pilot randomized controlled trial of the refined dHealth tool with parents. We will randomly assign groups to receive either the parenting skills training plus the tool (N=5 groups, 30 parents) or parenting skills training without the tool (N=5 groups, 30 parents). Exploratory analyses will examine the potential mediating mechanism of skill utilization (immediate and sustained) for optimizing the association between the dHealth intervention and improved child and parenting outcomes and the potential moderating effect of parent ADHD/EF functioning and internalizing mental health dimensions.
