The Center for Attachment Research uses the Coding Interactive Behavior (CIB) global rating scheme (developed by Ruth Feldman, 1998) to objectively assess the progress of families participating in the Group Attachment-Based Intervention (GABI) program. At each meeting, a three- to five-minute video of parent-child unstructured play is viewed and coded via group consensus using 45 individual scales from the CIB manual, with a primary focus on reflections of parental sensitivity vs. intrusiveness, child involvement vs. withdrawal, and dyadic reciprocity; additional clinical and domestic violence markers are also coded wherever relevant. While in this group we’re most interested in the behavioral effects and artifacts of responsive parenting on young children, the CIB system has broad utility for understanding dynamics in couples, families, etc., and is helpful for building/honing observation skills.
