This study compares the relationship between personality disorders and interpersonal problems as obtained by self-report and peer-report measures. Participants (N = 393) were administered self- and peer-report versions of the Peer Inventory for Personality Disorder and the Inventory of Interpersonal Problems-64. Canonical analyses demonstrated similar relationships between personality disorder features and interpersonal problems as measured by either self or peer. Analyses between self and peer found little shared variance across sources, indicating a large method variance. Results indicate that although similar constructs are identified by self and peers in their understanding of personality pathology and associated interpersonal problems, self-report information overlaps very little with information obtained from peers, underscoring the importance of obtaining multiple sources of information.
本研究比较了通过自我报告和同伴报告测量得出的人格障碍与人际问题之间的关系。参与者（N = 393）接受了人格障碍同伴量表和人际问题量表-64的自我报告版和同伴报告版。典型分析表明，无论是自我报告还是同伴报告所测量的人格障碍特征与人际问题之间的关系相似。自我报告与同伴报告之间的分析发现，不同来源之间几乎没有共同方差，表明存在较大的方法方差。结果表明，尽管自我报告和同伴报告在对人格病理学及相关人际问题的理解中识别出了相似的结构，但自我报告信息与从同伴那里获得的信息几乎没有重叠，这突出了获取多源信息的重要性。
