We aimed to assess the associations between pre-treatment personality traits on symptoms of posttraumatic stress disorder (PTSD) and depression before and after an intensive outpatient treatment program (IOP). In a secondary data analysis of a sample of = 665 veteran or active-duty U.S. military servicemembers who completed IOP treatment (65.7 % male; mean age = 41.8; 57.0 % White), we used multiple regression analyses and latent change score models to investigate pre-treatment measures of Five Factor Model traits, psychopathy, and narcissism as predictors of PTSD and depression symptoms across timepoints (i.e., from pre-treatment up to 12-months post-treatment) following completion of exposure-based, cognitive-behavioral IOP treatment. Neuroticism and Extraversion were positively and negatively, respectively, associated with PTSD and depression symptoms at all timepoints, and facets from other domains (e.g., trust, self-efficacy) also bore medium-to-large associations with these symptoms at each timepoint. Psychopathy and narcissism bore null-to-small relations with psychopathology. Pre-treatment PTSD and depression symptoms were consistent predictors of post-treatment symptoms, as well as of greater symptom reduction from pre- to post-treatment, pre-treatment to 12-month follow-up, and post-treatment to 12-month follow up. Higher Extraversion was significantly related to greater change in PTSD and depression symptoms from pre- to post-treatment. No other personality traits were related to symptom change beyond pre-treatment symptoms on any timescale. Personality traits have large associations with PTSD and depression symptoms over time, but the degree to which they account for IOP treatment response beyond baseline symptoms is relatively small.
我们旨在评估强化门诊治疗项目（IOP）前后，创伤后应激障碍（PTSD）症状及抑郁与治疗前人格特质之间的关联。在对665名完成IOP治疗的美国退伍军人或现役军人样本进行的二次数据分析中（65.7%为男性；平均年龄 = 41.8岁；57.0%为白人），我们使用多元回归分析和潜在变化分数模型，来研究五因素模型特质、精神病态和自恋的治疗前测量指标，作为基于暴露的认知行为IOP治疗完成后不同时间点（即从治疗前到治疗后12个月）PTSD和抑郁症状的预测因素。神经质和外向性分别与所有时间点的PTSD和抑郁症状呈正相关和负相关，其他领域的方面（如信任、自我效能感）在每个时间点也与这些症状存在中到高度的关联。精神病态和自恋与精神病理学的关系为零到较小。治疗前的PTSD和抑郁症状是治疗后症状的一致预测因素，也是从治疗前到治疗后、治疗前到12个月随访以及治疗后到12个月随访症状减轻程度的一致预测因素。较高的外向性与治疗前到治疗后PTSD和抑郁症状的更大变化显著相关。在任何时间尺度上，除治疗前症状外，没有其他人格特质与症状变化相关。人格特质随时间与PTSD和抑郁症状有很大关联，但它们在解释超出基线症状的IOP治疗反应方面的程度相对较小。
