When service members manifest symptoms of posttraumatic stress disorder (PTSD), intimate partners may engage in behaviors to accommodate their partners’ experiences (e.g., helping service members avoid situations that could make them uncomfortable, not expressing own thoughts and feelings to minimize PTSD-related conflict), which may inadvertently serve to maintain or increase PTSD symptoms over time. In a sample of 274 male service member/female civilian couples, we evaluated hypothesized bidirectional pathways between self-reported service member PTSD symptoms and partner accommodation, assessed four times over an approximately 18-month period. A random-intercept cross-lagged panel model disaggregating between and within effects revealed that, on average, couples in which the service member had higher levels of total PTSD symptoms also scored higher in partner accommodation, between-couple correlation, r = .40. In addition, at time points when service members’ PTSD symptoms were higher relative to their own average symptom level, their partners’ level of accommodation was also higher than their personal average, within-couple correlation r = .22. Longitudinally, service member PTSD symptom scores higher than their personal average predicted subsequent increases in partner accommodation, β = .19, but not vice versa, β = .03. Overall, the findings indicate both stable and time-specific significant associations between service member PTSD symptoms and partner accommodation and suggest that higher levels of PTSD symptoms are a significant driver of later increases in partner accommodation. These findings add further support for treating PTSD in an interpersonal context to address the disorder and concomitant relational processes that can adversely impact individual and relational well-being.

随着时间的推移，服务人员的创伤后应激障碍症状与伴侣适应之间的关联

当服务人员表现出创伤后应激障碍 (PTSD) 的症状时，亲密伙伴可能会采取一些行为来适应其伴侣的经历（例如，帮助服务人员避免可能使他们感到不舒服的情况，不表达自己的想法和感受以尽量减少与 PTSD 相关的冲突），随着时间的推移，这可能会无意中维持或增加 PTSD 症状。在 274 对男性服务人员/女性平民夫妇的样本中，我们评估了自我报告的服务人员 PTSD 症状和伴侣住宿之间假设的双向途径，在大约 18 个月的时间内评估了四次。一个在效应之间和效应内分解的随机截距交叉滞后面板模型显示，平均而言，r = .40。此外，在服役人员的 PTSD 症状相对于他们自己的平均症状水平更高的时间点，他们的伴侣的适应水平也高于他们的个人平均水平，夫妻内相关r= .22。从纵向上看，服务人员 PTSD 症状评分高于他们的个人平均水平，预测了伴侣住宿的后续增加，β = .19，但反之亦然，β = .03。总体而言，研究结果表明，服务人员 PTSD 症状与伴侣适应之间存在稳定且特定于时间的显着关联，并表明更高水平的 PTSD 症状是后来伴侣适应增加的重要驱动因素。这些发现进一步支持在人际关系环境中治疗 PTSD，以解决可能对个人和关系福祉产生不利影响的障碍和伴随的关系过程。
