Among Cambodian refugees attending a psychiatric clinic (n=100), 49% (49/100) had at least one episode of sleep paralysis (SP) in the previous 12 months. The annual and monthly SP prevalences were much higher in posttraumatic stress disorder (PTSD) than in non-PTSD patients. Among the PTSD patients, 65% (30/46) had monthly episodes of SP versus 14.85% (8/54) among non-PTSD patients (chi2[2, n=100]=26.78, P<.001). Moreover, patients with SP in the last month (n=30) versus those without SP had much higher PTSD severity scores. In the entire sample (n=100), the PTSD severity scores correlated significantly with the rate of SP in the last month. During SP, Cambodian refugees usually hallucinated an approaching figure (90%, 44/49). The rate of SP-associated and post-SP panic attacks was high, indicating the great distress caused by the phenomenon. SP seems to be a core aspect of the Cambodian refugee's response to trauma. When treating Cambodian refugees, and traumatized refugees in general, clinicians should assess for its presence.
在一家精神病诊所就诊的柬埔寨难民（n = 100）中，49%（49/100）在过去12个月中至少经历过一次睡眠瘫痪（SP）发作。创伤后应激障碍（PTSD）患者的年度和月度SP患病率远高于非PTSD患者。在PTSD患者中，65%（30/46）每月发作SP，而非PTSD患者中这一比例为14.85%（8/54）（卡方检验[2, n = 100] = 26.78，P <.001）。此外，上个月有SP发作的患者（n = 30）与没有SP发作的患者相比，PTSD严重程度得分要高得多。在整个样本（n = 100）中，PTSD严重程度得分与上个月的SP发作率显著相关。在SP发作期间，柬埔寨难民通常会幻觉到一个正在靠近的身影（90%，44/49）。与SP相关及SP发作后的惊恐发作发生率很高，表明该现象会造成极大痛苦。SP似乎是柬埔寨难民对创伤反应的一个核心方面。在治疗柬埔寨难民以及一般的受创伤难民时，临床医生应评估是否存在SP。
