0339 Feasibility and Acceptability Testing of a Digital Website Prototype to Promote Bedtime Routines in School-Aged Children

Abstract Introduction More than one-third of children across the United States do not obtain enough sleep. Digital sleep interventions have been proven to effectively improve sleep duration in children, as well as health outcomes in the parent-child dyad. Preliminary implementation testing of a digital website prototype tool to promote parent-child engagement during bedtime routines was conducted among a sample of parents of children 6-10 years old to determine feasibility and acceptability of the tool, prior to pilot testing the intervention. Methods Three measures included in the validated Implementation Feasibility Questionnaire (Acceptability of Intervention Measure (AIM); Intervention Appropriateness Measure (IAM); and Feasibility of Intervention Measure (FIM) were administered to seven parents of school-aged children with mild sleep problems. Response items were on a 5-point Likert scale (1 = completely disagree; 5 = completely agree). Parents also completed an adapted version of Program Feedback Questionnaire to assess the following implementation science domains: usefulness, usability, acceptability, accessibility, usable/findable, feasibility, credibility, desirability and value, of the website prototype. Response options were reverse coded, with lower values indicating higher ratings (1 = strongly agree; 5 = strongly disagree). Mean scores were calculated for each implementation domain aforementioned. Results Mean scores for the Implementation Feasibility Questionnaire were reported as follows: AIM measure responses averaged 4.75; IAM measure responses averaged 4.78; and FIM measure responses averaged 4.67. Mean scores for the Program Feedback Questionnaire sub-domains were reported as follows: usefulness: 1.3; value: 1.0; acceptable: 1.0; usable/findable: 1.3; accessible: 2.1; feasible: 1.5; desirable: 1.4; credible: 1.4. Conclusion The website prototype was highly received, and implementation of the website intervention appears feasible and acceptable by parents of young children. Ongoing data collection will bolster sample size and continue to provide evidence towards intervention development. Support (if any)
