FASTT Telehealth Behavioral Support Service for Caregivers of Children With Developmental Delay or Disability

The first three months of the project period will be used for planning and development, including cultural, content, and logistic adaptation and development of the evaluation procedures. During the next seven months, the adapted service will be implemented. The remaining two months of the project will be used for analysis of the evaluation data and creating the final report.

Implementation Plan. Integrating FASTT into the Undivided service platform will leverage the existing infrastructure and procedures of Undivided to link for families to FASTT Support Specialists. The Undivided infrastructure uses dedicated Care Navigators to assess family needs, provide assistance and encouragement in addressing those needs, and offer guidance and best practices to empower parents. The existing Undivided infrastructure uses a customized web-based and mobile app that provides messaging to the navigator support team for in-the-moment help and advice regarding service access and utilization, as well as a knowledgebase repository with expert-curated guides to support and navigation topics. Importantly, Undivided connects families to an online community of other caregivers of children with disabilities, effectively adding a peer support network for parents to share experiences, knowledge, and encouragement. The current Care Navigator team is focused on supporting families in accessing services, and stops short of making recommendations related to behavioral support.

Although family navigation services like Undivided have demonstrated efficacy in connecting families to services and reducing barriers to access, that function is dependent on the availability of services in the local community. Often, accessible services are not available to meet the needs of families due to insufficient capacity or the lack of flexible delivery methods. While availability of services has been an ongoing challenge for early intervention, it has been exacerbated by the advent of coronavirus disease 2019 (COVID-19) pandemic restrictions that reduced staffing and curtailed in-person support. These reductions have had significant negative effects on child behavior and caregiver stress and have disproportionately impacted families of color or those in low-resource circumstances. The FASTT service provides families with immediate expertise and support based on established principles of child development.

Undivided Care Navigators receiving support requests through the online app will identify family needs that fit within the FASTT scope of support. The FASTT scope focuses on three areas: 1) reducing child behavior problems, including sleep, feeding difficulties and picky eating, fearfulness, fussiness, tantrums, and defiant behavior; 2) addressing concerns about child development, including understanding what is typical vs. delayed development, having appropriate developmental expectations, knowing when to seek specialized support, and understanding how to promote healthy development through scaffolding; and 3) managing parenting stress, including maintaining work/life balance issues, regulating emotions, and reducing stress arising from concerns about attachment and parent/child relationship issues.

Caregivers requesting support in these areas will be provided with the FASTT line number which they can text to connect with a live Support Specialist. After a caregiver connects, they will be given the opportunity to continue the conversation by text or switch to a phone call at their preference. The Support Specialist begins with a set of discovery questions to understand the support topic, information about the strengths and challenges of the child, a history of the behavior, and what the caregiver has already tried to address the topic. Next, the Support Specialist suggests tips and advice drawn from established evidence-based practices (EBP) strategies and probes to determine the level of acceptance the caregiver has with the strategies. Motivational interviewing practices are used to support caregivers in selecting strategies that they feel they can implement. Recommendations are purposefully designed to be easily incorporated into caregivers' demanding schedules of tasks and activities. Conversations range from a few minutes to an hour or longer and can extend to days or weeks as caregivers may pause the conversation and return later when time is available. Strategies employ a strength-based approach that helps caregivers simultaneously facilitate skill development and diminish unwanted behaviors for their child. Parents can reach back out at any point for additional support or to share progress.

Experimental Design and Assessment Plan. This project will employ descriptive reporting of feasibility and acceptability, and quantitative analysis using a single-group pre and post program design. The primary outcomes of interest will be for feasibility and acceptability (see Table 1). Exploratory outcomes will include preliminary indications of impact on parenting stress and sense of competence, both general and for the specific topic of behavior support. Feasibility measures will include number of families who engaged in the service as a percent of those offered participation, the total number of sessions delivered, and characteristics of the sessions (e.g. length of text exchanges, span of case resolution in minutes or days, follow-up sessions on the same topic, and follow-up sessions on a different topic). Feasibility assessment will also include feedback from Undivided Care Navigators on ease of connecting families to the support and from the FASTT Support Specialists on ease and perceived efficacy of delivering support sessions. Acceptability measures will capture post-program perceptions of caregivers' satisfaction with the service (e.g. usefulness of the content, ease of access, and acceptability of telehealth delivery). Quantitative analysis will include pre and post evaluations collected at the program level (i.e. measures collected before and approximately two weeks after participating the in the FASTT program) and at the session level (i.e. brief measures collected at the beginning and end of support sessions). Pre-program assessment will include caregiver and family demographics (race/ethnicity, socioeconomic status, employment, developmental delay or disability of their child), general perceptions of parenting stress, parenting sense of competence, the topic of behavior or development they want support with (including frequency and intensity of challenging behaviors), and their stress and perceived self-efficacy around the specific behavior. Post-program assessment will include the same measures of general parenting stress and sense of competence, specific assessment of changes in stress and self-efficacy around the topic of the support session.

Data Analysis Plan. For Specific Aim 1, analysis will include descriptive numerical (e.g., mean, standard deviation, range) and visual depictions (e.g., histogram) of feasibility measures, including service engagement proportion, total number of delivered sessions, as well as session characteristics. We will also measure the metrics of support session delivery to enable future estimates of the cost of service provision.

For Specific Aim 2, we will first conduct descriptive numerical and visual depictions of acceptability measures of caregivers' satisfaction with the service (e.g., ratings of the degree to which participants found the program useful, easy to access, and respectful of their values). These acceptability measures are all based on a 1-to-7 rating scale, with "1" indicating extremely dissatisfied and "7" indicating extremely satisfied. To gauge the acceptability of this text-based support service, we will test the hypothesis that participants' average service satisfaction measures are all above 4 (indicating neither dissatisfied nor satisfied). Hypothesis testing will be performed using one-tail one-sample t-tests, although the non-parametric Wilcoxon signed-rank test will be used if the assumption of normality of the scores is not met. Sensitivity analyses in G*Power indicate that the proposed sample of 30 participants will allow us to detect a moderate-sized effect (Cohen's d = .46) with power of at least 0.80 (α = .05) in a one-tail one-sample t-test. With the one-tail non-parametric Wilcoxon signed-rank test, the proposed sample size of 30 will allow us to detect a moderate-sized effect (Cohen's d = .48) with power of .80 and α = .05.

For Specific Aim 3, exploratory analysis of impact measures will be performed using paired-sample t-tests to determine if post-program scores for parenting stress and parenting sense of competence significantly improve from corresponding pre-program scores (i.e., lower parenting stress, higher parenting sense of competence).If the assumption of normality of the scores is not met, the paired-sample non-parametric Wilcoxon signed-rank test will be used instead. Similar to hypothesis 2, sensitivity analyses in G*Power indicate that the proposed sample of 30 participants will allow us to detect moderate-sized effects (Cohen's d = .46 for regular paired-sample t-tests; Cohen's d = .48 for Wilcoxon signed-rank test) with statistical power of 0.8 and α of .05.

Exploratory analysis will also be conducted to examine potential heterogeneity in outcome variables of feasibility, acceptability, and program impact outcomes that may be explained by family demographics or child DD type. Both of these analyses will only be used to assess the promise of an intervention effect. More rigorous tests of efficacy will be conducted in Phase 2. All assessments will be self-administered by families and staff via an online survey platform to provide ease of access and flexibility. An option will be available to have a research assistant administer the assessments for families for whom self-administered, Internet-based surveys may pose a barrier.
