This study used latent profile analysis (LPA) to identify differing classes of psychopathic traits in a large sample of military personnel (90.7% Army National Guard) and examined how membership across profiles can be differentiated by mean scores on external correlates relevant to psychopathy and/or to military service (e.g., aggression, posttraumatic stress symptoms, impulsivity). Psychopathy was operationalized via the three-factor model of the Levenson Self-Report Psychopathy Scales (LSRP; Brinkley et al. 2008; Levenson et al. 1995). LPA revealed optimal fit for a four-profile solution. Three profiles had roughly equivalent within-profile means across the three factors, characterized by below average, average, and above/high average LSRP scores. The fourth profile emerged as qualitatively different: high on LSRP-Callous but below average on LSRP-Egocentricity and LSRP-Antisocial. The four profiles were differentiable based on their mean scores on external correlates, suggesting varied implications for externalizing and internalizing features across psychopathic trait configurations in a military sample. Implications for studying psychopathy in military and other novel samples are discussed.

这项研究使用了潜在特征分析（LPA）来识别大量军事人员（90.7％陆军国民警卫队）样本中不同类别的精神病性状，并研究了如何通过与心理疾病和/或疾病相关的外部相关因素的平均得分来区分不同特征的成员或服兵役（例如，侵略，创伤后压力症状，冲动）。精神病通过Levenson自我报告精神病量表的三因素模型进行操作（LSRP； Brinkley等人，2008； Levenson等人，1995）。LPA揭示了四轮廓解决方案的最佳配合。三个配置文件在三个因素中的配置文件内均值大致相等，其特征在于LSRP得分低于平均，平均和高于/高于平均。第四个特征在质量上有所不同：LSRP-Callous较高，但LSRP-Egocentricity和LSRP-Antisocial低于平均值。这四个配置文件是基于它们在外部相关性上的平均分数而可区分的，这暗示了在军事样本中跨精神病性状构型外部化和内部化特征的各种含义。讨论了在军事和其他新颖样本中研究精神病的意义。
