The Impact of a Infant Sleep Hygiene Training Program on Infant Sleep Habits and Parental Self-Efficacy

This randomized controlled trial aims to evaluate the effectiveness of a structured, Infant Sleep Hygiene Education Program initiated during pregnancy on infant sleep habits and parental self-efficacy related to infant sleep in the postpartum period. The program is grounded in developmental science and attachment-sensitive principles and focuses on promoting healthy sleep habits through responsive caregiving, consistent bedtime routines, and evidence-based sleep hygiene practices.

Pregnant women will be randomly assigned to either an intervention group receiving a multi-session prenatal education program with postnatal follow-up support, or a control group receiving routine antenatal care. Primary outcomes include parental self-efficacy regarding infant sleep and infant sleep habits (e.g., night awakenings, sleep duration, sleep onset latency, and routine consistency), assessed at 1, 3, and 6 months postpartum.

Secondary outcomes include adherence to recommended sleep-supportive parenting practices and infant sleep diary indicators. In addition, the mediating role of parental self-efficacy in the relationship between the intervention and infant sleep outcomes will be examined. Program evaluation outcomes will assess parental knowledge before and after the education, participation and adherence to the sessions, and parental satisfaction with the education program.

This study aims to provide evidence for an ethical, developmentally appropriate, and preventive infant sleep education model integrated into routine prenatal care.
