The present investigation examined the associations among thwarted belongingness (TB), emotion regulation difficulties (ERD), and posttraumatic stress disorder (PTSD) symptom severity among firefighters. First, the associations of TB and ERD with PTSD symptom severity were evaluated. Second, the indirect effect of TB on PTSD symptom severity through ERD was examined. The sample included 246 trauma-exposed firefighters (M age = 40.21, SD = 9.93, 93.1% male) who completed an online questionnaire battery. Results demonstrate significant, positive associations among TB, ERD, and PTSD symptom severity; and an indirect effect of TB on PTSD symptom severity through heightened ERD (β = 0.17; CI [0.08, 0.29]). Alternate indirect effect models were also significant, underscoring the potentially bidirectional associations of these variables. These findings suggest that there is merit in investigating the role of interpersonal factors and ERD among firefighter populations to better understand PTSD symptomatology. Clinical and empirical implications are discussed.

本调查检查了消防员受挫的归属感 (TB)、情绪调节困难 (ERD) 和创伤后应激障碍 (PTSD) 症状严重程度之间的关联。首先，评估了 TB 和 ERD 与 PTSD 症状严重程度的关联。其次，通过 ERD 检查了 TB 对 PTSD 症状严重程度的间接影响。样本包括 246 名受过创伤的消防员（M年龄 = 40.21，SD = 9.93, 93.1% 男性）谁完成了在线问卷调查。结果表明 TB、ERD 和 PTSD 症状严重程度之间存在显着的正相关；TB 通过增加 ERD 对 PTSD 症状严重程度产生间接影响（β = 0.17；CI [0.08, 0.29]）。替代的间接效应模型也很重要，强调了这些变量的潜在双向关联。这些发现表明，调查人际因素和 ERD 在消防员人群中的作用，以更好地了解 PTSD 症状学是有价值的。讨论了临床和经验意义。
