Impact of Bedtime Routines on Sleep and Development in Toddlers

Study Overview
=================
Brief Summary
-----------------
Investigators will recruit up to 100 families (children aged 12.0 to 14.9 months and their primary caregivers) at their scheduled 12-month well child care infant visit at Temple Pediatric Care. The purpose of this randomized controlled trial is to examine the impact of implementation of a bedtime routine program, Connect, Calm, & Comfort: 3 Cs for Bedtime ZZZs, to promote better sleep and improve developmental outcomes in toddlers from primarily low-income families.

Detailed Description
-----------------
A bedtime routine is a key factor in the promotion of not only healthy sleep, but also potentially of broad development and wellbeing in early childhood. A bedtime routine, in and of itself, embodies the characteristics of nurturing care and early child stimulation especially for at-risk children. It is consistent with the Lancet Early Childhood Series Steering Committee emphasizing the need for nurturing care, which includes adequate health, nutrition, security and safety, responsive caregiving, and early learning opportunities, to help young children (ages 0-5 years) reach their full developmental potential, and to build a strong foundation for subsequent development, health, and wellbeing. Common, adaptive components of a bedtime routine can contribute to an array of positive developmental outcomes beyond improved sleep, inclusive of language development, literacy, child emotional and behavioral regulation, parent-child attachment, and family functioning, among other outcomes. Although studies have been conducted on the relationship between bedtime routines and sleep, there have been few studies looking at bedtime routines and other developmental outcomes.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: 100 caregiver-infant dyads (infants ages 12.0 to 14.9 months) will be recruited from Temple Pediatric Care Outpatient Pediatric office with follow-up visits at approximately 15 and 24 months of age.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Bedtime Routine Education<br>50 families will be randomly assigned to receive the bedtime routine intervention, 3 Cs for Bedtime ZZZs delivered by research assistants at the 12-month and 15-month well-child visits, in additional to receiving usual clinical care. The intervention will take approximately 30-45 minutes to implement at each study visit. Research assistants will be trained and supervised by board-certified Behavioral Sleep Medicine providers. This intervention focuses on developing an individualized bedtime routine, including such activities as a bath, teeth-brushing, reading stories, singing songs, and cuddling, based on parent's preferences. Families will receive appropriate materials for their bedtime routine, including a CuddleBright kit, bedtime books, toothbrush/toothpaste, and the created bedtime chart to take home. | Behavioral: Bedtime Routine Education<br>* The intervention aims to promote healthy sleep and improved developmental outcomes in infants. Individualized bedtime routine education, including such activities as a bath, teeth-brushing, reading stories, singing songs, and cuddling will be implemented by research assistants at the 12-month well-child visit. Reinforcement of the bedtime routine education will be implemented at the 15-month visit. Each individualized bedtime routine will incorporate 3-5 steps and a bedtime routine chart depicting those steps will be created and provided to the families. Families will receive materials for their bedtime routines, including a CuddleBright kit, 1-2 additional bedtime books, toothbrush/toothpaste , and the created bedtime chart. On top of that, families will also receive a children's book provided by Reach Out and Read through the study period.<br>|
| No Intervention: Control group<br>50 families will be randomly assigned to control group (usual care). | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in sleep outcomes | Caregivers will report on their toddlers sleep in the previous 2 weeks at baseline (12 months of age) and at 15-months and 24-months, using the well-validated and widely used Brief Infant Sleep Questionnaire-Revised (Short Form) (BISQ-R). The BISQ-R contains items related to the child sleep environment (e.g., sleep space, location, and arrangement) and patterns (e.g., bedtime, sleep onset latency, night awakening frequency and duration, wake time). Items also assess caregiver-perceived child sleep problems (e.g., overall sleep problem severity, bedtime resistance severity). The BISQ-R has 3 subscales, Infant Sleep, Parent Behavior, and Parent Perception. Scores range from 0-100, with higher scores denoting better sleep. | 15-month and 24-month visits | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Developmental outcomes | The Ages & Stages Questionnaires (ASQ) is an age-specific, reliable and well-validated measure to predict developmental outcomes. Caregivers will report on their infant/child's communication and personal-social skills. Each domain consists of 6 questions and each question is scored with 10 points for yes, 5 for sometimes, and 0 for no, yielding scores ranging from 0 to 60 for each domain. Lower scores denote potential developmental concerns. | 15-month and 24-month visits | 
| Socio-emotional outcomes | The Brief Infant-Toddler Social and Emotional Assessment (BITSEA) is a screener derived from the longer ITSEA. It is a parent questionnaire that assesses the social-emotional development of children ranging in age from 12 to 36 months. Caregivers will rate each statement that best describes the child's behavior in the past month, with scores ranging from 0 to 84. Higher scores denote possible social-emotional/ behavioral concerns. | 15-month and 24-month visits | 
| Parent stress | The Parenting Stress Index (PSI) Short form is a 36-items reliable measure to assess total parenting stress with high internal consistency. It consists of three subscales: parental distress, parent-child dysfunctional interaction, and difficult child. Statements on this measure are rated on a 5-point Likert scale from strongly agree to strongly disagree, with scores ranging from 36 to 180. Higher scores denote higher level of stress in parent-child relationship. | 15-month and 24-month visits | 
| Treatment acceptability | Caregivers randomized to the bedtime routine education arm will complete the treatment acceptability/bedtime routine evaluation form. Caregivers will rate 7 statements related to the perceived helpfulness/efficacy and acceptability of the intervention using a 5-point Likert scale from strongly disagree to strongly agree, with total scores ranging from 0 to 35. Higher scores indicate higher perceived helpfulness and acceptability of the intervention. | 15-month and 24-month visits |
