The Impact of an Interactive Guidance Intervention on Sustained Social Withdrawal in Preterm Infants in Chile: Randomized Controlled Trial.

Background: Sustained social withdrawal is a key indicator of child emotional distress and a risk factor for psychological development. Preterm infants have a higher probability of developing sustained social withdrawal than infants born full-term during their first year.

Objective: To compare the effect of a behavioral guidance intervention to that of routine pediatric care on sustained social withdrawal behavior in preterm infants.

Interactive Guidance Intervention to Address Sustained Social Withdrawal in Preterm Infants in Chile: Protocol for a Randomized Controlled Trial.

Background: Preterm newborns can be exposed early to significant perinatal stress, and this stress can increase the risk of altered socioemotional development. Sustained social withdrawal in infants is an early indicator of emotional distress which is expressed by low reactivity to the environment, and if persistent, is frequently associated with altered psychological development. Infants born prematurely have a higher probability of developing sustained social withdrawal (adjusted odds ratio 1.
