Comparing the second-order factor structure of the Family Environment Scale across husbands' and wives' perceptions of their family environment.

The Family Environment Scale (Moos & Moos, 1986) is one of the most widely used environmental measures in clinical and family research. Clinicians and researchers often use the FES for comparing spouses' perceptions of their family environment, under the assumption that the underlying structure of the FES is the same for husbands and wives. However, no studies have actually compared the structure of the FES across spouse responses to the FES. Additionally, a review of the literature generally suggests a lack of consensus regarding the factor structure of the FES. Using confirmatory factor analyses, we examined whether the second-order factor structures of the FES, as identified in the literature, were consistent across spouses' perceptions of their family environment. Husbands and wives in 130 nonclinical families responded to Form R of the FES. The findings supported the two-factor solution presented by Fowler (1981) and by Boake and Salmon (1983), and did not differ across responses by husbands and wives. In contrast, responses by husbands and wives to the FES could not be modeled using the three-factor solutions presented by Moos and Moos (1986) and by others. The importance of using a measure that is structurally the same across different groups of respondents is discussed.
