Assessing behavioral interventions for infant sleep problems using computer-vision technology

The current study aimed to assess parents' experiences in implementing infant behavioral sleep interventions (BSIS) in a real-world setting, and whether BSIS are linked with objective infant sleep and parent-reported well-being.

To assess parents' experiences in implementing infant behavioral sleep interventions (BSIS) in a real-world setting, and whether BSIS are linked with objective infant sleep and parent- reported well-being. 


Parents of 4,925 infants (47%f), aged 1-20 mo (M=7.9, SD=4.9) completed an online survey reporting use of BSIs, sleepiness, sleep quality, and depressive symptoms. Auto-videosomnography (ie, computer-vision technology) was collected over 14-days to assess infant sleep patterns. 


The majority (65%) of parents reported implementing BSIs with their infants. Extinction-based BSIs were implemented for shorter periods of time, were rated as more difficult but more helpful than Parental Presence (all p<0.0001). Infants who underwent Extinction- based methods had longer and more consolidated sleep than those who had not implemented any BSIs, and those who had undergone Parental Presence (33.9 mins and 47.2 mins more sleep, respectively). BSI use was associated with better parental sleep quality, but not parental sleepiness or depressive symptoms. 


Real-world implementation of infant behavioral sleep interventions is highly prevalent, and linked with longer and more consolidated infant nighttime sleep. Future work is warranted to examine the effects of infant age at implementation on sleep outcomes.
