ABSTRACT

Objective:To systematically examine the efficacy of mindfulness-based stress reduction (MBSR) for post-traumatic stress disorder (PTSD).Methods:A systematic literature search was performed in multiple databases,including Cochrane Library,Pubmed,MEDLINE,Embase,Web of Science,CBM,CNKI,WanFang Database.Paper inclusion criteria were confined to intervention trials of MBSR conducted in patients with PTSD.Revman5.3 and Stata12.0 was used to get pooled results.Results:A total of 8 studies were included,4 randomized controlled trials (including 255 patients with PTSD) and 4 self-controlled studies (including 152 patients with PTSD).Comparing to control groups,MBSR groups resulted in statistically significant improvements on symp toms of PTSD [SMD =-0.53,95 ％ CI(-0.87--0.19),P ＜ 0.05].The symptoms of PTSD after the intervention was improved [SMD =-1.95,95％ CI(-2.84--1.07),P ＜0.01].There was no statistically significant difference between the data of follow-up and post-intervention [SMD =-0.26,95％ CI(-0.77-0.26),P ＞0.05].ContusionIt suggests that the mindfulness-based stress reduction (MBSR) may be effective in reducing symptoms of post-traumatic stress disorder and have stable short-term effects.
