Using an intensive short-term longitudinal design, this study first examined whether there were significant differences in maternal sensitivity and intrusiveness after completion of Attachment and Biobehavioral Catch-up (ABC; Dozier & the Infant-Caregiver Project Lab, 2013) when compared to a control condition. The second aim was to explore the rate and shape of change in parenting behaviors. Participants were 24 mothers and their biological children, who were randomly assigned to ABC (n = 13) or a control condition (n = 11). A structured play assessment with each mother and her child was video-recorded prior to randomization into the study, before each intervention session, and at a follow-up visit. A total of 270 videos were coded for sensitivity and intrusiveness. Hierarchical linear growth models were used to estimate the total change in parenting qualities across the 10 intervention sessions when comparing ABC to a control condition. Piecewise hierarchical linear growth models were used to investigate patterns of change across the intervention for mothers within ABC. Mothers in the ABC condition showed greater increases in sensitivity and decreases in intrusiveness than mothers in the control condition. There was evidence for nonlinear patterns of change in sensitivity and intrusiveness among mothers in ABC. These results support the effectiveness of ABC in changing sensitivity quickly.
