Marital Quality Assessment: Reviewing the Concept, Instruments, and Methods

This study aimed to investigate which instruments have been used in marital quality research since 2005, and the concepts underlying each measure. We conducted a literature review in the following databases: PsycINFO, PubMed, Web of Science, and BVS. The review included 91 studies investigating 21 instruments. Half of the scales were multidimensional, but the most used instruments were unidimensional, except for the DAS. Most measures had exploratory evidence of construct validity and did not provide a definition of the construct under evaluation. Theoretical development is needed to address the problem of largely subjective, empirically based measures. We suggest network models can help to develop new measures and to provide a fresh understanding of the construct and the dynamics of marital relations.
