Marriage and couple relationships constitute an area of intense interest for researchers as well as policymakers. One of the goals of the Healthy Marriages study is to inform current discussions regarding the measurement of aspects of the quality of marital relationships. This literature review and annotated bibliography represent several products of Child Trends’ project to review the state of the art in measuring couple relationships. The literature review and bibliography included here provide information on the psychometric properties of existing measures/tools used in current research on couple relationships across abroad range of sub-populations. These populations include: cohabiting couples, stepfamilies and remarried families, families who are co-parenting after the couple relationship has ended, families with children, families in which one or more partners in a couple is in the military, and families in which one or more partners in a couple is incarcerated. We also provide information on the psychometric properties of general measures that have been widely used in the literature, as well as measures that have been used to capture societal norms, values, and attitudes. The review contains psychometric information on measures of marriage from published papers and studies, most of which were conducted during the past decade. The review is not exhaustive, but rather abroad representation of the type and quality of measures that have been previously used. The review of the psychometric properties of existing measures is intended to be a useful tool for the development of measures of healthy marriage for future research and evaluation. (Author abstract)
