THE USE OF STRUCTURAL EQUATION MODELING IN ASSESSING THE QUALITY OF MARITAL OBSERVATIONS

The authors examine traditional analytic approaches to assessing the quality of observational measures and suggest a structural equation modeling (SEM) approach that extends the multitrait-multimethod tradition to assess both reliability and validity of observational data. Drawing on observations of hostility and coercion in marital interactions obtained with the Iowa Family Interaction Rating Scales (J. Melby et al., 1990), the authors illustrate the use of SEM as a means to evaluate estimates of psychometric properties of both observational ratings and family member reports within the same analytic framework, thereby providing more comparable assessments across study informants. The results demonstrate the utility of this approach.
