Seventy Years of Research on Personality and Close Relationships: Substantive and Methodological Trends Over Time

Abstract

The present review is based on a quantitative analysis of the abstracts for 477 studies published since 1932 on the topic of personality and close (romantic) relationships. This approach enables a "bird's-eye" view of the content and methods that have characterized research in this area and an examination of publication trends over time. Results showed that 60% of all published studies in this area relied exclusively on cross-sectional and self-report methods; that nearly all used convenience samples, though more than half used nonstudent samples; and that more than one-third relied exclusively on data from individuals rather than couples. Few studies appeared to include elaborated networks of constructs in either the personality or relationship domain or to attempt to integrate an elaborated model of personality with an elaborated relationship model. Examination of trends over time revealed a mixed picture, with increasing use of the least informative designs balanced by evidence of increasingly complex conceptual models.
