Study summary

The SHIP study is a randomized controlled trial of an intervention for preschool children with sleep problems, in which we aim to give parents the knowledge, motivation, and skills necessary to set goals, problem-solve, and improve their child's sleep. In collecting three years of follow-up data, we will be able to determine the impact of the SHIP intervention on childhood sleep problems, obesity, academic achievement, and emotional and behavioral problems, as well as parental stress and daytime tiredness. This study has the dual potential to expand treatment resources for young children with behavioral sleep problems and to increase our scientific understanding of the long-term consequences of early childhood sleep problems.

Study arms

  • Experimental
    SHIP Intervention

    SHIP is a health behavior change intervention to give parents the knowledge, motivation, and skills necessary to set goals, problem-solve, and improve their child's sleep.

    Behavioral: SHIP (Sleep Health in Preschoolers)

  • Active comparator
    SHIP Control Arm

    The active control arm uses the same strategies as the SHIP intervention arm, but for child health topics unrelated to sleep or outcome measures.

    Behavioral: SHIP Control Arm

Interventions

  • BehavioralSHIP (Sleep Health in Preschoolers)

    SHIP (Sleep Health in Preschoolers) is a family-centered health behavior change intervention for child behavioral sleep problems delivered 1:1 to parents via a home visit and follow-up phone calls.

  • BehavioralSHIP Control Arm

    Families will receive a family-centered health behavior change intervention for child health topics unrelated to sleep or outcome measures, delivered 1:1 to parents via a home visit and follow-up phone calls.
