Conceptual and Empirical Approaches to Developing Family‐Based Assessment Procedures: Resolving the Case of the Family Environment Scale

Abstract

This article focuses on the reliability and validity of the Family Environment Scale (FES). The FES subscales generally show adequate internal consistency reliability and stability over time when applied in samples that are diverse; the items also have good content and face validity. An extensive body of research supports the construct, concurrent, and predictive validity of the FES. More generally, reliability and validity are a joint function of scale items and response formats and of the characteristics and diversity of specific samples. To contribute to further advances in family assessment, researchers need to use both conceptual and psychometric criteria rather than rely too heavily on the pursuit of internal consistency reliability and factor analytic approaches to scale construction and validation.
