The purpose of this study was to examine associations between maladaptive personality traits and satisfaction in various relationships using a co\u2010twin control design to identify potential environmental contributions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>The sample consisted of 1340 older adult twin participants from the Minnesota Twin Registry (<jats:italic>M<\/jats:italic><jats:sub>age<\/jats:sub>\u2009=\u200970.3) that completed the Personality Inventory for DSM\u20105 Faceted Brief Form and Network of Relationships Inventory (Revised for Older Adults).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Several maladaptive personality traits were phenotypically associated with relationship dissatisfaction, with detachment and negative affect having the largest effects. Further, within twin pair differences in detachment and negative affect were associated with greater relationship dissatisfaction, suggesting that observed associations were mediated partly by the unique environment, not solely the result of genetic and familial confounding.
