OBJECTIVE To determine latent classes of treatment receipt among people with comorbid posttraumatic stress disorder (PTSD) and substance use disorder (SUD) and describe each class by demographics, disease characteristics, and psychiatric diagnoses. METHOD Participants were National Epidemiologic Survey on Alcohol and Related Conditions-III respondents with lifetime PTSD and SUD (n = 1,349; mean age 40.3; 62.5% female; 30.9% non-White or Hispanic-White). Cross-sectional data were collected using the DSM-5 Alcohol Use Disorder and Associated Disabilities Interview Schedule. Latent class analysis was used to identify subgroups of participants with different patterns of treatment receipt. RESULTS Of the patients, 36% received at least 1 SUD treatment while 84% received at least 1 mental health (MH) treatment. Six latent classes were identified: no treatment (17.3%), outpatient MH (34.0%), outpatient + inpatient MH (17.9%), SUD (7.3%), SUD + outpatient MH (15.7%), and SUD + outpatient MH + inpatient MH (7.7%). The SUD treatment classes evidenced greater social instability, had higher alcohol use disorder symptom severity, and used more drug types than the non-SUD classes. Classes receiving inpatient MH treatment had a greater incidence of additional comorbid conditions and suicidal behaviors. Across all 6 classes, most respondents met diagnostic criteria for chronic PTSD (overall: 68.9%) while fewer met diagnostic criteria for chronic SUD (overall: 38.7%). CONCLUSIONS Most people with lifetime PTSD and SUD have sought either SUD or MH treatment or both, with substantially greater receipt of MH treatment. This comorbid group has complex clinical presentations that differ depending upon treatment subgroup, and for most, their PTSD persisted despite high rates of treatment engagement.

患有同时发生的创伤后应激障碍 (PTSD) 和物质使用障碍的个体的治疗接受模式。

目的 确定合并有创伤后应激障碍 (PTSD) 和物质使用障碍 (SUD) 的人接受治疗的潜在类别，并通过人口统计学、疾病特征和精神病学诊断来描述每个类别。方法 参与者是关于酒精和相关疾病的国家流行病学调查-III 终生患有 PTSD 和 SUD 的受访者（n = 1,349；平均年龄 40.3；62.5% 为女性；30.9% 为非白人或西班牙裔白人）。使用 DSM-5 酒精使用障碍和相关残疾访谈表收集横断面数据。潜在类别分析用于识别具有不同治疗模式的参与者亚组。结果 在这些患者中，36% 接受了至少 1 次 SUD 治疗，而 84% 接受了至少 1 次心理健康 (MH) 治疗。确定了六个潜在类别：未治疗 (17.3%)、门诊 MH (34.0%)、门诊 + 住院 MH (17.9%)、SUD (7.3%)、SUD + 门诊 MH (15.7%) 和 SUD + 门诊 MH + 住院 MH (7.7%) . 与非 SUD 班级相比，SUD 班级表现出更大的社会不稳定性，酒精使用障碍症状严重程度更高，并且使用的药物类型更多。接受住院 MH 治疗的班级有更高的其他合并症和自杀行为的发生率。在所有 6 个类别中，大多数受访者符合慢性 PTSD 的诊断标准（总体：68.9%），而符合慢性 SUD 诊断标准的受访者较少（总体：38.7%）。结论 大多数终生患有 PTSD 和 SUD 的人都曾寻求过 SUD 或 MH 治疗，或两者都寻求过，接受 MH 治疗的人要多得多。这个共病组具有复杂的临床表现，根据治疗亚组的不同而有所不同，并且对于大多数人来说，尽管治疗参与率很高，但他们的 PTSD 仍然存在。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
