About this study

Official title: Prevention Strategies to Enhance Young Children's Sleep Development - Part 2

The goal of this pilot randomized controlled trial is to test the feasibility, acceptability, and preliminary signal of effect of a combined school- and home-based sleep promotion program for young children prior to the kindergarten transition.

Read the detailed description

This pilot randomized controlled study will test a combined school- and home-based sleep promotion intervention designed to improve young children's sleep and classroom behavior. Classrooms will be randomized to either the intervention or waitlist control group. Intervention content will be delivered via text message to parents' phones and in the classroom. The primary aim of this study is to assess the feasibility and acceptability of the intervention. The secondary aim is to assess the preliminary signal of effect on children's sleep and classroom behavior. Findings from this study will inform any necessary intervention modifications prior to a fully powered randomized controlled trial.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Rested & Ready to LearnBehavioural

    The intervention targets improving young children's sleep by providing parents with sleep education and activities to do at home with their child. Classroom teachers will also deliver a brief lesson aligned with intervention topics to reinforce key messaging in the classroom. The sleep intervention will focus on the benefits of sleep (physical health, social-emotional health, classroom participation/learning), creating and sticking to a bedtime routine, screen use before bed, and developmentally appropriate sleep behavior.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Trial-related feasibility - recruitment capability

    Recruitment capability will be measured by the proportion of eligible children who enroll at baseline

    Measured: Through recruitment period, up to 6 weeks

  2. Trial-related feasibility - retention

    Retention will be measured by the proportion of enrolled children who remain in the study through the length of the intervention. Reasons for dropout will also be assessed

    Measured: Weekly through study completion (weeks 1-5)

  3. Intervention-related feasibility - intervention fidelity

    Intervention fidelity, the delivery of the intervention as originally planned, will be assessed via teacher report. Intervention fidelity will be assessed with a study-specific questionnaire to assess if all classroom components were delivered as planned.

    Measured: Weekly through study completion (weeks 1-4)

  4. Intervention-related feasibility - rate of attendance

    Children's attendance at school during intervention sessions will be provided by class records.

    Measured: Weekly through study completion (weeks 1-4)

  5. Intervention-related feasibility - participant adherence to intervention (home)

    Adherence to the home-based component will rely on link usage data to assess parent engagement with the online materials. Investigators will extract information related to the number of parents who click links from weekly material and number of parents who do not open links.

    Measured: Weekly through study completion (weeks 1-4)

  6. Intervention-related feasibility - participant adherence to intervention (school)

    School-based adherence will be assessed by a teacher-completed survey which will indicate whether or not they implemented the intervention each week

    Measured: Weekly through study completion (weeks 1-4)

  7. Intervention-related feasibility - data collection completion rates

    Data collection completion rates will be calculated to understand the feasibility of data collection protocols

    Measured: Weekly through study completion (weeks 1-4)

  8. Intervention-related feasibility - data collection feasibility

    Feasibility of data collection procedures will be assessed with qualitative feedback from parents during semi-structured interviews following the study.

    Measured: Post-intervention (week 5-9)

  9. Acceptability

    Acceptability of the intervention conditions is defined as participants' perception that the intervention is satisfactory and will be assessed with short weekly questionnaires for parents and teachers. Overall acceptability will be assessed with an exit-survey consisting of Likert-scale items and open-ended responses to understand likes/dislikes, content, logistics, and feedback for future iterations. Likert-style questions will have response options ranging from 1-5 with greater scores representing higher acceptability.

    Measured: Weekly through study completion (weeks 1-4), post-intervention (week 5-9)

Secondary outcomes (7)

  1. Child sleep - device-based duration

    Objective nocturnal sleep duration will be assessed using Axivity AX3 accelerometers worn on the non-dominant wrist for 7 days. Raw accelerometry data will be processed with open-source software, GGIR.

    Measured: Baseline (week 0), post-intervention (week 5), follow up (week 17)

  2. Child sleep - device-based timing

    Objective sleep timing will be assessed using Axivity AX3 accelerometers worn on the non-dominant wrist for 7 days. Raw accelerometry data will be processed with open-source software, GGIR.

    Measured: Baseline (week 0), post-intervention (week 5), follow up (week 17)

  3. Child sleep - Bedtime Routines Questionnaire

    Parents will complete the Bedtime Routines Questionnaire which contains 31 items on a 5-point Likert scale. This questionnaire results in two subscales - bedtime routine consistency and routine behaviors and environment. Higher scores indicate more consistent bedtime routines.

    Measured: Baseline (week 0), post-intervention (week 5), follow up (week 17)

  4. Child behavior

    Parents and teachers will complete the Child Self-Regulation and Behavior Questionnaire (CSBQ, ~10 min) which contains 34 items describing children's typical self-regulation and social behaviors in the home (parent version) and classroom (teacher version). Respondents describe what the child's behavior is like on a five-point scale ranging from "Not true" to "Very true." The CSBQ provides the following subscales: self-regulation, sociability, externalizing problems, internalizing problems, and prosocial behavior. The CSBQ is valid and reliable in children ages 3-6 years.

    Measured: Baseline (week 0), post-intervention (week 5), follow up (week 17)

  5. Child inhibition

    nhibition (i.e., the ability to control behavioral impulses) will be assessed with the Go/No-Go task in which children are asked to identify fish and avoid sharks shown on the screen on an iPad as part of the freely accessible Early Years Toolbox. An impulse control score is calculated (% Go Accuracy x % No-Go Accuracy), which reflects the child's ability to withhold their response in the context of the strength of that typical (pre-potent) response.

    Measured: Baseline (week 0) and post-intervention (week 5)

  6. Child working memory

    Working memory (i.e., amount of information that can be coordinated in the mind) will be assessed with the Mr. Ant task in which children will recall and identify the location of colorful stickers on Mr. Ant's body on an iPad as part of the freely accessible Early Years Toolbox. For the Mr Ant task, scores are calculated using a point score calculated as: beginning from level 1, one point for each consecutive level in which at least two of the three trials were performed accurately, plus 1/3 of a point for all correct trials thereafter.

    Measured: Baseline (week 0) and post-intervention (week 5)

  7. Child cognitive flexibility

    Cognitive flexibility (i.e., the ability to control and redirect attention) will be assessed with the Card Sorting task in which children will sort cards by color and then shape on an iPad as part of the freely accessible Early Years Toolbox. For the Card Sorting task, investigators tend to review the accuracy of Block 1 (pre-switch) and Block 2 (post-switch). Since a post-switch accuracy score intends to index the extent to which a child could successfully switch from one sorting rule to the next, investigators will swap the two scores if the post-switch accuracy is larger than the pre-switch accuracy. This ensures that final post-switch scores (Block 2 + Block 3) reflects the child's ability to successfully switch between sorting rules.

    Measured: Baseline (week 0) and post-intervention (week 5)
