Is It Adaptive for People With Personality Problems to Know How Their Romantic Partner Perceives Them? The Effect of Meta-accuracy on Romantic Relationship Satisfaction

People with personality disorder (PD) symptoms tend to report and have partners who report lower quality relationships with them. Using a large community sample of romantic couples, the current research tested whether the established link between PD symptoms and partner-reported relationship quality was attenuated by meta-accuracy (insight into the impression one makes) as well as whether the link between PD symptoms and self-reported relationship quality was attenuated by positivity (assuming one makes a desirable impression). Results suggested that meta-accuracy for core personality traits moderated the link between PD symptoms and partner-reported relationship quality, such that high meta-accuracy attenuated whereas low meta-accuracy exacerbated the negative association between PD symptoms and quality. However, individuals with symptoms did not necessarily reap the same relational benefits of their meta-accuracy, and positivity did not moderate the link between their symptoms and relationship quality. Implications for assessment and whether meta-accuracy should be improved are discussed.
