Abstract: | An instrument is described that is used to assess interaction style in parent-infant dyads in which the infant is handicapped or developmentally delayed. The rating scales were designed to be easy to use by professionals and trained nonprofessionals, to be applicable to children who are functioning between birth and 18 months developmental age, and to involve a minimal time commitment so that they could be used in the context of early intervention programs. The rating scales cover intrusive, responsive, and general social behavior by the parent and social and avoidant behavior by the child. Successful implementation of these scales is described. |
