在物质使用障碍（SUD）的治疗中，使用人格来对患者进行分型有着悠久的历史。然而，没有人使用正常范围人格的结构模型来验证SUD患者的类型学，特别是表明亚型在治疗过程和结果上是否不同。我们在退伍军人事务部医疗中心的196名参加住宅SUD治疗的退伍军人中开发了一种基于个性的类型学。在治疗开始、治疗1个月和治疗结束时对患者进行评估。在治疗开始时，使用多维人格量表-简表评估人格。潜伏特征分析确定了3组解决方案，包括低病理，内化和外化组。内化组在治疗开始时的功能指标得分最低，而外化组在治疗过程和住院期间的结果得分更低（e.例如，在一个实施例中，与其他居民的关系更紧张，计划联盟更低）。这些研究结果支持基于3因素人格模型的SUD患者的临床有意义的类型学，并可作为未来努力的指导，旨在制定有针对性的干预措施，以解决该人群中患者的个体差异。
There is a long history of using personality to subtype patients in treatment for substance use disorders (SUD). However, no one has validated a typology of SUD patients using a structural model of normal-range personality, particularly indicating whether subtypes differ on treatment processes and outcomes. We developed a personality-based typology among 196 military veterans enrolled in residential SUD treatment at a Veterans Affairs medical center. Patients were assessed at treatment entry, 1 month into treatment, and at discharge from treatment. Personality was assessed using the Multidimensional Personality Questionnaire-Brief Form at treatment entry. Latent profile analyses identified a 3-group solution consisting of low pathology, internalizing, and externalizing groups. The internalizing group scored lowest on measures of functioning at treatment entry, whereas the externalizing group scored more poorly on treatment processes and outcomes over the course of their residential stay (e. g., more stressful relationships with other residents, lower program alliance). These findings support a clinically meaningful typology of SUD patients based on a 3-factor model of personality and can serve as a guide for future efforts aimed at developing targeted interventions that can address the individual differences of patients in this population.
