THE TWO previous papers in this series reported on the theoretical framework and method for evaluating the "Family Interaction Scales" and on the data analysis and research findings.1,2 This paper will focus on some of the methodological issues of the research and on a discussion of the substantive findings. Details on the theory, method, and research findings were covered in the first two papers and will not be repeated here.
