Abstract

Background

Behavioral sleep interventions (BSIs) for infants are ubiquitous, yet knowledge about their implementation in real-world settings is limited. This study aimed to compare the frequency, timing, duration, difficulty, and helpfulness of real-world implementation of three BSI approaches: Unmodified Extinction, Modified Extinction, and Parental Presence. It additionally aimed to compare infant sleep, parent sleep, daytime sleepiness, depression, and parent-infant bonding between parents who had and had not implemented these interventions.

Methods

Participants were 2090 parents of US infants (49% girls) aged 3-18 months (M=9.1, SD=4.1). Parents completed online questionnaires regarding their infant's sleep, their own sleep quality, daytime sleepiness, depression levels, and parent-infant bonding. Infant sleep was assessed objectively via auto-videosomnography, obtained from the 14-day period prior to survey completion.

Results

Implementation of BSIs was common, with 63.8% of parents reporting implementation of at least one BSI. The average infant age at the time of intervention was 5.3 months (SD=2.6) and did not differ between groups. Unmodified and Modified Extinction were rated as significantly more difficult to implement compared to Parental Presence but also as more helpful, shorter, and quicker to show improvements. Auto-videosomnography revealed that infant nighttime sleep was longer and more consolidated in the Unmodified and Modified Extinction groups compared to the Parental Presence and no BSI groups. Finally, no differences were found between BSI groups in any of the parent measures.

Discussion

Implementation of BSIs outside clinical settings is pervasive, and occurs earlier than generally recommended by clinicians (i.e., <6 months). Implementation of Unmodified and Modified Extinction was associated with longer and more consolidated infant sleep. Despite concerns regarding the potential harm of BSIs, implementation of these approaches was not linked with parent sleep, daytime sleepiness, depression, or parent-infant bonding, providing additional evidence for the safety and potential benefits of these interventions.
