Abstract

This study has two purposes. First, the study evaluates the reliability of self-reports of argumentativeness by comparing self-reported argumentativeness with two other reports of the same target: evaluations by friends and evaluations by intimates. Second, the study examines whether particular characteristics presage a larger or smaller disparity in different reporters’ reports. We found the reliability of both the approach and avoidance subscales to be acceptable for the intimate partner’s responses, but only marginally acceptable when the scale was answered by a friend; on a basic level, we did not find individuals over or under-estimating their level of argumentativeness, self-over and under estimating has limited impact on the self-reporting of argumentativeness, though males are more likely to over-report argumentativeness; and while relational history had little effect on other-reports, there were effects for same-sex couples that should be further explored.
