Mindfulness-based interventions have recently been shown to be a promising option for treating posttraumatic stress. The current study aimed to investigate the effects of an online mindfulness-based intervention on ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) symptoms at a 3-month follow-up.
An RCT design with three measurement points (pre-intervention, post-intervention, and 3-month follow-up) was used to investigate the effects of an 8-week online mindfulness intervention. In total, 53 traumatized young adults ( = 23.21, = 2.81; 84.9% female) participated in the study: 17 in the intervention group and 36 in the waiting list control group.
Intervention group and waiting list control group comparison revealed that the intervention was effective for reducing CPTSD disturbances in self-organization symptoms ( = -0.84 [-1.44; -0.24]), specifically, negative self-concept ( = -0.66 [-1.25; -0.07]) and disturbances in relationships ( = -0.87 [-1.47; -0.27]), at 3-month follow-up. There were no between-group effects for PTSD symptoms from pre-test to follow-up.
This is one of the first RCT studies to report follow-up effects of an online mindfulness-based intervention for ICD-11 PTSD or CPTSD symptoms. Our study yielded that the effects of mindfulness-based internet intervention on CPTSD symptoms tend to retain over time.

基于正念的干预措施最近已被证明是治疗创伤后应激障碍的一个有前景的选择。本研究旨在调查一项基于正念的在线干预措施在3个月随访时对国际疾病分类第11版（ICD - 11）创伤后应激障碍（PTSD）和复杂性创伤后应激障碍（CPTSD）症状的影响。
采用随机对照试验（RCT）设计，有三个测量点（干预前、干预后和3个月随访），以研究为期8周的在线正念干预的效果。共有53名受过创伤的年轻成年人（平均年龄 = 23.21岁，标准差 = 2.81岁；84.9%为女性）参与了该研究：干预组17人，等待名单对照组36人。
干预组与等待名单对照组的比较显示，在3个月随访时，该干预措施对于减轻CPTSD自我组织症状方面的紊乱（效应量 = -0.84 [-1.44；-0.24]）有效，具体而言，对消极自我概念（效应量 = -0.66 [-1.25；-0.07]）和人际关系紊乱（效应量 = -0.87 [-1.47；-0.27]）有效。从预测试到随访，PTSD症状在组间没有差异。
这是首批报告基于正念的在线干预措施对ICD - 11 PTSD或CPTSD症状随访效果的随机对照试验研究之一。我们的研究表明，基于正念的网络干预对CPTSD症状的影响往往会随着时间推移而持续存在。
本研究已在ClinicalTrials.gov注册（NCT编号：NCT04333667；https://clinicaltrials.gov/ct2/show/NCT04333667）。于2020年4月3日注册。
