Acute stress disorder (ASD) refers to the symptoms associated with posttraumatic stress disorder (PTSD) within the first four weeks following the traumatic event. Recent theoretical models suggest that early detection of ASD provides an opportunity to implement early interventions to prevent the development of PTSD or ameliorate its symptomatology. The aim of the present study was the evaluation of the efficacy of an ASD treatment for earthquake victims, which would serve as an early intervention for PTSD. A single-case (n = 1) quasi-experimental design was used, with pre and post-assessments, as well as one, three and six-month follow-ups, with direct treatment replications. Fourteen participants completed the treatment and the follow-up measurements. The results obtained using a single-case analysis showed significant clinical improvement and clinically significant change when employing a clinical significance analysis and the reliable index of change. Statistical analyses of the dataset displayed statistically significant differences between the pre and post-assessments and the follow-up measures, as well as large effect sizes in all clinical measures. These results suggest that the treatment was an efficacious early intervention for PTSD during the months following the traumatic event, although some relevant study limitations are discussed in the text.

早期认知行为干预对墨西哥地震受害者急性应激障碍的疗效

急性应激障碍 (ASD) 是指在创伤事件发生后的前 4 周内与创伤后应激障碍 (PTSD) 相关的症状。最近的理论模型表明,早期发现 ASD 为实施早期干预以预防 PTSD 的发展或改善其症状提供了机会。本研究的目的是评估 ASD 治疗对地震受害者的疗效,这将作为 PTSD 的早期干预。单例(n= 1) 使用准实验设计,进行前后评估,以及 1、3 和 6 个月的随访,直接重复治疗。十四名参与者完成了治疗和后续测量。当采用临床意义分析和可靠的变化指数时,使用单病例分析获得的结果显示出显着的临床改善和临床显着变化。数据集的统计分析显示了评估前和评估后以及后续措施之间的统计学显着差异,以及所有临床措施中的大效应量。这些结果表明,在创伤事件发生后的几个月内,该治疗是对 PTSD 的有效早期干预,尽管文中讨论了一些相关的研究限制。
