Measurement issues have plagued attachment research over the past 30 years. Concerns range from limitations of the original paragraph measure (C. Hazan & P. R. Shaver, 1987), low reliability of continuous scales of Bartholomew's 4‐category measure, limited interpretation of the 2 dimensions of the Experience of Close Relationships and the Experience of Close Relationships‐Revised (ECR/ECR‐R; K. A. Brennan, C. L. Clark, & P. R. Shaver, 1998; R. C. Fraley, N. G. Waller, & K. A. Brennan, 2000), and time‐consuming coding of attachment interviews. In this article, a revision of the Relationship Scales Questionnaire (RSQ) is introduced. The new 4‐category scales were found to have improved internal consistency when compared with the original RSQ scales as well as moderate to high test–retest reliability and good construct validity, thereby providing an alternative measure for researchers who are interested in assessing the effects of the 4‐category model of attachment.
