DO FIRST-YEAR INTERVENTION EFFECTS ENDURE - FOLLOW-UP DURING TODDLERHOOD OF A SAMPLE OF DUTCH IRRITABLE INFANTS

This study evaluated the enduring effectiveness of a skill-based train ing program to enhance maternal sensitivity between 6 and 9 months of age. 82 mothers and their toddlers were evaluated at 18 and 24 months, and 79 at 31/2 years on the bases of observations of free play, every day interaction, problem solving, and peer interaction. Most of the si gnificant behavioral changes noted in the second year pertain to attac hment security, indices of maternal sensitivity across situations, and child cooperation. Some enduring effects on indices of sensitivity ap pear to be attachment-mediated. In the third year, results revealed di rect enduring intervention effects on parental responsiveness and chil d cooperation. Attachment-mediated effects were evident for maternal a ssistance, child security, and positive peer contact. Attachment patte rn also predicted differences in attractiveness of the focal child as an interactive partner.
