We examined the impact of a home visiting intervention on 227 adolescent mothers' parenting attitudes. At enrollment, half of mothers were at risk for child maltreatment. Mothers assigned to intervention (n = 161) received home visits and case management. Intervention and comparison mothers (n = 66) participated in monthly peer group meetings. Regression analyses controlling for enrollment differences indicated that intervention group mothers had significant improvements in 3 of 5 subscales and in total Adult-Adolescent Parenting Inventory-2 scores relative to the comparison group.
