Abstract
Purpose:Posttraumatic stress disorder(PTSD)is a significant global mental health concern,especially in the military.This study aims to estimate the efficacy of mindfulness meditation in the treatment of military-related PTSD,by synthesizing evidences from randomized controlled trials.Methods:Five electronic databases(Pubmed,EBSCO Medline,Embase,PsychINFO and Cochrane Library)were searched for randomized controlled trials focusing on the treatment effect of mindfulness medi-tation on military-related PTSD.The selection of eligible studies was based on identical inclusion and exclusion criteria.Information about study characteristics,participant characteristics,intervention de-tails,PTSD outcomes,as well as potential adverse effects was extracted from the included studies.Risk of bias of all the included studies was critically assessed using the Cochrane Collaboration's tool.R Statis-tical software was performed for data analysis.Results:A total of 1902 records were initially identified and screened.After duplicates removal and title&abstract review,finally,19 articles in English language with 1326 participants were included through strict inclusion and exclusion criteria.The results revealed that mindfulness meditation had a signifi-cantly larger effect on alleviating military-related PTSD symptoms compared with control conditions,such as treatment as usual,present-centered group therapy and PTSD health education(standardized mean difference(SMD)=-0.33;95％CI[-0.45,-0.21];p＜0.0001).Mindfulness interventions with different control conditions(active or non-active control,SMD =-0.33,95％CI[-0.46,-0.19];SMD =-0.49,95％CI[-0.88,-0.10],respectively),formats of delivery(group-based or individual-based,SMD =-0.30,95％CI[-0.42,-0.17],SMD =-0.49,95％CI[-0.90,-0.08],respectively)and intervention durations(short-term or standard duration.SMD =-0.27,95％CI[-0.46.-0.08],SMD =-0.40,95％CI[-0.58,-0.21],respectively)were equally effective in improving military-related PTSD symptoms.Conclusion:Findings from this meta-analysis consolidate the efficacy and feasibility of mindfulness meditation in the treatment of military-related PTSD.Further evidence with higher quality and more rigorous design is needed in the future.
