消防员患创伤后应激障碍（PTSD）的风险更高，这强调了了解临床可针对性因素以告知循证干预措施发展的重要性。享乐能力，或体验快乐的能力，是奖励功能的一个方面。快感缺乏（即，快乐能力低或缺乏）是PTSD的标志性症状。痛苦耐受力（DT），或承受负面情绪状态的感知能力，也被证明与PTSD有关。本研究的目的是探讨自我报告的快乐能力（Snaith-Hamilton快乐量表）和DT（痛苦耐受量表）的主要和交互作用的PTSD症状的严重程度的消防员。分层线性回归进行了802创伤暴露的职业消防员，谁完成了电池的自我报告问卷的样本。协变量包括创伤负荷（即，创伤类型的数量）、消防服务年限和抑郁症状（不包括快感缺乏）。快乐能力（B = 2.71，SE = 0.95，p = 0.005）和DT（B =-0.21，SE = 0.03，p <0.001）与PTSD症状严重程度呈递增相关。快乐能力和DT的交互作用与PTSD症状严重程度的增加相关（B = 0.25，SE = 0.07，p <0.001）。在创伤暴露的消防员中，享乐能力和DT与创伤后应激障碍症状严重程度的升高独立和交易相关。这些研究结果提供了证据，在制定干预措施，目标DT和消防员，特别是那些经历创伤后应激障碍的患者的享乐能力受损的效用。
Firefighters are at heightened risk of posttraumatic stress disorder (PTSD), underscoring the importance of understanding clinically targetable factors to inform evidence-based intervention development. Hedonic capacity, or the ability to experience pleasure, is a facet of reward functioning. Anhedonia (i.e., low or absent hedonic capacity) is a hallmark symptom of PTSD. Distress tolerance (DT), or the perceived ability to withstand negative emotional states, has also demonstrated associations with PTSD. The purpose of the present study was to examine the main and interactive effects of self-reported hedonic capacity (Snaith-Hamilton Pleasure Scale) and DT (Distress Tolerance Scale) on PTSD symptom severity among firefighters. A hierarchical linear regression was performed among a sample of 802 trauma-exposed career firefighters, who completed a battery of self-report questionnaires. Covariates included trauma load (i.e., number of trauma types), years in the fire service, and depression symptoms (excluding anhedonia). Both hedonic capacity (B = 2.71, SE = 0.95, p = 0.005) and DT (B = −0.21, SE = 0.03, p < .001) were incrementally associated with PTSD symptom severity. The interactive effect of hedonic capacity and DT was associated with heightened PTSD symptom severity (B = 0.25, SE = 0.07, p < .001). Hedonic capacity and DT were independently and transactionally associated with heightened PTSD symptom severity among trauma-exposed firefighters. These findings provide evidence for the utility in developing interventions that target DT and impaired hedonic capacity among firefighters, particularly those experiencing PTSD symptomatology.
