Increasing maternal sensitivity to infant distress through attachment-based intervention: a randomized controlled trial.

Maternal sensitivity to infant distress is a key predictor of infant attachment security and social-emotional development. Preventive interventions that support mothers' sensitive responses to infant distress are crucial, as are rigorous evaluations that test such interventions are effective. The current randomized controlled trial tested main and moderated effects of an attachment-based intervention on mothers' sensitivity to their infants' distress in 161 low-income, predominantly Latino mother-infant dyads.
