Psychometric information was determined for two scales commonly used in early intervention programs and research, the Family Support Scale (FSS) (C. J. Dunst and others, 1984) and the Family Resource Scale (FRS) (C. J. Dunst and H. E. Leet, 1985). These questionnaires measure the perceptions of support for families with children with disabilities and the adequacy of resources for families with young children in general. Data come from longitudinal efficacy studies conducted at 17 sites nationwide with a combined sample of nearly 1,000 families. Reliability, validity, and factor structure were investigated for these measures with 990 families. Both classical and confirmatory methodologies were used in the analyses. Results suggest that the FSS and FRS are stable, internally consistent measures that appear to measure familial perceptions of support and resources adequately. The factor structure of each is probably more accurately represented by these studies than previous analyses. Twelve tables contain details of the analyses. (SLD)
