这项研究评估了 280 名创伤后应激障碍 (PTSD) 筛查呈阳性的个体的非适应性和适应性人格表 (SNAP; Clark, 1996) 的心理测量特征。将 SNAP 有效性、特质、气质和人格障碍 (PD) 量表与多维人格问卷简表上的量表进行比较（Patrick、Curtin 和 Tellegen，2002 年）。在 86 名退伍军人的子样本中，还与国际人格障碍检查（IPDE；Loranger，1999）（一项半结构化诊断访谈）进行了比较，对 SNAP PD、特质和气质量表进行了评估。结果显示，SNAP 量表具有良好的收敛效度，其与人格和 PD 相关测量的关联模式证明了这一点。然而，它们与其他人格和 PD 测量相关的区分有效性的证据更加复杂，并且 SNAP 特质和气质量表的测试分数在 IPDE 评估的 PD 中留下了许多无法解释的差异。 SNAP PD 量表的诊断评分大大夸大了相对于 IPDE 的 PD 患病率估计值，并且与 IPDE 的一致性较差。相比之下，维度 SNAP 分数与 IPDE 上的连续分数产生了更强的关联。 SNAP 量表也在很大程度上证明了与 PTSD 严重程度衡量标准的预期关联模式。总体而言，研究结果支持在这一人群中使用这一测量方法，并有助于我们对气质、PTSD 和 Axis II 精神病理学之间关联的概念化。（PsycINFO 数据库记录 (c) 2016 APA，保留所有权利）
This study evaluated the psychometric characteristics of the Schedule for Nonadaptive and Adaptive Personality (SNAP; Clark, 1996) in 280 individuals who screened positive for posttraumatic stress disorder (PTSD). The SNAP validity, trait, temperament, and personality disorder (PD) scales were compared with scales on the Brief Form of the Multidimensional Personality Questionnaire (Patrick, Curtin, & Tellegen, 2002). In a subsample of 86 veterans, the SNAP PD, trait, and temperament scales were also evaluated in comparison to the International Personality Disorder Examination (IPDE; Loranger, 1999), a semistructured diagnostic interview. Results revealed that the SNAP scales have good convergent validity, as evidenced by their pattern of associations with related measures of personality and PD. However, evidence for their discriminant validity in relationship to other measures of personality and PD was more mixed, and test scores on the SNAP trait and temperament scales left much unexplained variance in IPDE-assessed PDs. The diagnostic scoring of the SNAP PD scales greatly inflated prevalence estimates of PDs relative to the IPDE and showed poor agreement with the IPDE. In contrast, the dimensional SNAP scores yielded far stronger associations with continuous scores on the IPDE. The SNAP scales also largely evidenced expected patterns of association with a measure of PTSD severity. Overall, findings support the use of this measure in this population and contribute to our conceptualization of the association between temperament, PTSD, and Axis II psychopathology.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
