The Working Model of the Child Interview (WMCI) is a 30-75 minute semi-structured interview developed by Zeanah, Benoit, & Barton in 1986 to formally assess a caregiver's internal representations (perceptions and subjective experience) of their child and relationship with the child. The traditional 3-way WMCI coding scheme allows for classification of caregivers' representations of their child in one of three major classifications (balanced, disengaged, distorted). The WMCI and its two coding schemes can be used with caregivers from pregnancy to any child age (no upper limit with respect to child's age).
