Larger-scale feasibility trial of the families moving forward (FMF) connect mobile health intervention for caregivers raising children with fetal alcohol spectrum disorders

Abstract

Objective Caregivers raising children with fetal alcohol spectrum disorders (FASD) have limited access to evidence-based supports. This single-arm feasibility trial assesses the Families Moving Forward (FMF) Connect app to determine readiness for a larger randomized controlled trial (RCT). Methods Eligibility for this online trial included caregivers of children (ages 3–12) with FASD residing in the United States. Caregivers received FMF Connect for 12 weeks on their personal smartphones (iOS or Android). Pre- and post-assessments included child behavior, parenting and family functioning, and app quality; user experience interviews were conducted post-intervention. Usage and crashes were monitored. Study objectives assessed feasibility of the trial (recruitment, attrition, measure sensitivity), intervention (technical functionality, acceptability), and implementation (caregiver usage). Results Recruitment strategies proved sufficient with 171 caregivers screened and 105 deemed eligible. Analyses identified a few predictive demographic and outcome variables related to attrition. Several study measures were sensitive to change. Additional trial and measurement improvements were identified. From a technological perspective, the FMF Connect app was functional; the Android prototype required more
