The Infant CARE-Index (ICI) is an attachment measure that involves a 3-minute video recording of a typical play interaction between a caregiver and infant, birth to 15 months. The ICI was developed by Patricia Crittenden. Unlike many attachment measures, the ICI does not involve caregiver separation. The ICI measures relational and developmental risk within the context of the dyad. The ICI assesses caregivers on three measures: sensitivity, control, and unresponsiveness. The ICI assesses infants on four measures: cooperativeness, compulsivity, difficulty, and passivity.
