A System for Tailoring Change Measures to the Individual Family

The focus of this project is the problem of evaluating change in families. Prior work has tended to limit itself to anecdotal or self‐report data. By and large, the studies that have evaluated a family intervention by observing family interactions have failed to demonstrate change. A major drawback in such studies has been the assumption that the few interaction variables selected (e.g., amount of silent time) have roughly the same salience and meaning for all the families studied. The measurement system described here was developed to fulfill four methodological requirements: (a) to represent the family as a whole; (b) to be sensitive to change; (c) to contain multiple measures; and (d) to be adaptable to the variation among families. The solution to these requirements, presented here, is a system for tailoring measures to individual families.
