Observational couple assessment: a cross-model comparison

This study compared the clinical rating scales from the Circumplex Model (CCRS), the McMaster Model of Family Functioning (MCRS) and the Family Health Scales (FHS). A central purpose was to investigate whether observational rating scales designed to measure family functioning can also be used to assess couple functioning. One hundred and sixty-six drug abusing women, receiving primary drug treatment in two metropolitan drug agencies in the southwest of the US, and their partners were videotaped while engaged in three couple tasks prior to receiving any treatment. The main findings indicated that all three rating scales have: (1) sufficient interrater reliability; (2) good construct validity, as reflected in factor analyses; and (3) very good convergent validity. However, there was some concern about whether these scales are as discriminating when measuring couples as they are when assessing families.
