Personality Disorder in Social Networks: Network Position as a Marker of Interpersonal Dysfunction.

The present study investigated social network position as a marker of interpersonal functioning in personality disorders. Participants were groups of military recruits (N=809) in 21 training groups. Participants completed self- and informant-versions of the Multisource Assessment of Personality Pathology, acting as both targets and judges in a round-robin design. Network characteristics were associated with both self- and peer-reported personality disorder traits. Consistent with DSM-IV descriptors, measures of centrality and degree connectivity were positively associated with Narcissistic and Histrionic PDs, and negatively associated with Avoidant, Schizoid, and Schizotypal PDs.
