A collaborative effort to study mother—child interaction in three risk groups: Social risk mother,adolescent mother,preterm infant

This paper describes the collaborative efforts of three intervention projects with similar data sets on high-risk populations of mothers and their children at 13 and 20 months. The three projects collected data on a total of 190 dyads from three risk groups: adolescent mothers and their infants, high social risk mothers and their infants, and high social risk mothers and their preterm infants. The authors define the common set of measures and resulting variables used collaboratively to measure parent-child interaction and compare the three risk groups at both 13 and 20 months.
