Measuring relationship quality in an international study: Exploratory and confirmatory factor validity

This chapter describes on the operationalisation and testing of the newly developed Relationship Quality (RQ) scale, designed to assess an individual's perception of his or her RQ in their current partnership. It utilises the cross-sectional, community sample from the combined data set, drawn primarily from the United Kingdom, United States, and Australia. The chapter aims to develop a scale that measures the positive aspects of a relationship, namely, RQ, using a large international diverse community sample. After the review of relationship satisfaction/quality scales, the chapter outlines the process of scale development with specific reference to RQ. According to J. M. Graham et al. and J. L. Funk and R. D. Rogge: The Locke-Wallace Marital Adjustment Test (MAT), the Kansas Marital Satisfaction Scale (KMSS), the Quality of Marriage Index (QMI), the Relationship Assessment Scale (RAS), and B. R. Karney and T. N. Bradbury's semantic differential scale, are the most commonly used relationship satisfaction scales.
