The observational coding scales originating from
the Beavers Systems Model (BIS), the three instruments originating from the McMasters Model (FAD, MCRS, and MICS), the observational IFIRS and CCRS, and the self - report FAM - III and FRI were all classified as «well - established.»
Comparisons of self - report measures of
the Beavers Systems Model and Olson's Circumplex Model.
Beavers, W. R. & Hampson, R. B. «Measuring Family Competence:
The Beavers Systems Model.»
Validity was measured by correlating the SFI with the observational scales of
the Beavers System Model.
The Beavers System Model integrates Family Systems Theory and Developmental Theory to understand family health or pathology (Franklin, Cody & Jordan, 2004).
