ABSTRACTObjective: Mindfulness-based interventions (MBIs) are clinically effective forinsomnia, but the research findings have been mixed. This meta-analysis ofrandomized controlled trials (RCTs) examined the effect of MBIs on insomnia.Method: Both English (PubMed, PsycINFO, Embase, and Cochrane Librarydatabases) and Chinese (WanFang and CNKI) databases were systematicallyand independently searched. Standardized mean differences (SMDs) and riskratio (RR) with their 95% confidence intervals (CIs) were calculated using therandom effects model. Results: Five RCTs (n = 520) comparing MBIs (n = 279)and control (n = 241) groups were identified and analyzed. Compared to thecontrol group, participants in the MBIs group showed significant improvementin insomnia as measured by the Pittsburgh Sleep Quality Index (n = 247; SMD:−1.01, 95% CI: −1.28 to −0.75, I2 = 0%, p < 0.00001) at post-MBIs assessment.Conclusion: In this comprehensive meta-analysis, MBIs appear to be effective inthe treatment of insomnia. Further studies to examine the long-term effects ofMBIs for insomnia are needed.
Insomnia is a common sleep disorder that is associated with increased risk of physical comorbidities,psychiatric disorders, impaired social function (Gong et al., 2016; Li et al., 2015; Ohayon & Bader,2010), and all-cause mortality (Araujo et al., 2017). Insomnia has been estimated to affect up to athird of the population globally based on different diagnoses (Ohayon, 2002). Common strategies fortreating insomnia include pharmacotherapy and psychosocial interventions, such as cognitivebehavioral therapy (CBT) and mindfulness-based interventions (MBIs). Both pharmacotherapyand psychosocial interventions are widely used to treat insomnia (Hohagen et al., 1994). CBT hasbeen regarded as a first-line treatment for chronic insomnia in many countries (Perlis & Smith,2008), with satisfactory effectiveness (Cheng & Dizon, 2012; Wang, Wang, & Tsai, 2005).
Mindfulness-based interventions (MBIs) are often used in treating insomnia (Wong et al.,2017; Zhang et al., 2015) and could improve insomnia and sleep quality (Black, O’Reilly,Olmstead, Breen, & Irwin, 2015; Bowden, Gaudry, An, & Gruzelier, 2012; Crain, Schonert-Reichl, & Roeser, 2017; Rao, Metri, Raghuram, & Hongasandra, 2017; Wong et al., 2017).

Mindfulness emphasizes the awareness that emerges through purposeful attention to the presentmoment, with an accepting and nonjudgmental attitude (Kabat-Zinn, 2003). MBIs aim to reduceworry about the past or the future, and focus on everyday activities (Kanen, Nazir, Sedky, &Pradhan, 2015). MBIs consist of a number of brief interventions that incorporate mindfulness asa principle (Strauss, Cavanagh, Oliver, & Pettman, 2014), including the Mindfulness-BasedCognitive Therapy (MBCT), Mindfulness-Based Stress Reduction (MBSR) and other approacheswith modified or integrated mindfulness components. Of them, MBCT and MBSR are the mostwidely used in treating psychiatric disorders and related problems (Strauss et al., 2014). MBSRwas developed from the ancient tradition of mindfulness mediation established by Kabat-Zinnet al in 1970s, and was used as a method of healing (Kabat-Zinn, 2003). In contrast, MBCT wasdeveloped in the 1990s by integrating MBSR with cognitive therapy elements, which is now usedin the maintenance treatment for depression and insomnia (Kuyken et al., 2016; Segal, Williams,& Teasdale, 2012; Wong et al., 2017). Studies of insomnia treatments have compared MBIs andpharmacotherapy (Gross et al., 2011; Cohen’s d = −0.64 in sleep efficiency), CBT and pharma-cotherapy (Jacobs, Pace-Schott, Stickgold, & Otto, 2004; Cohen’s d = 1.1 in sleep efficiency), andMBIs and CBT (Garland et al., 2014; Cohen’s d = −2.76 in sleep efficiency), but the findingshave been mixed.
Several meta-analyses (Gong et al., 2016; Kanen et al., 2015) were conducted to examine the effect ofMBIs on sleep problems, but studies involving subjects with major medical conditions, such as cancerand osteoarthritis, were not excluded. Major medical conditions, including physical and psychiatriccomorbidities and medication-caused side effects, could influence the effect of MBIs on insomnia andlimit the generalizability of the findings (O’Donnell, 2004). In addition, several recent RCTs ofMBIs havebeen published and not been included in previous meta-analyses (Wei et al., 2017; Wong et al., 2017).
Thus, we performed a comprehensive meta-analysis of RCTs on MBIs for insomnia. We hypothe-sized that compared to control groups, MBIs would be more effective for improving insomnia.
Methods
Selection criteria
According to the PICOS acronym, the following inclusion criteria were used: Participants (P):participants with insomnia according to standardized diagnostic criteria, such as the ChineseClassification and Diagnostic Criteria for Mental Disorders, third edition (CCMD-3; Chen, 2002),the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV; AmericanPsychiatric Association, 1994), and the International Statistical Classification of Diseases andRelated Health Problems, 10th revision (ICD-10; World Health Organization, 1992). Intervention(I): MBIs group including MBIs alone or MBIs plus other treatments (e.g., health education).Comparison (C): control group; that is, receiving other intervention (i.e., pharmacotherapy orsleep hygiene education) and blank control or waitlist control. Outcomes (O): the primary outcomemeasure was insomnia at post-MBI assessment as measured using standardized rating scales, such asthe Pittsburgh Sleep Quality Index (PSQI) (Buysse, Reynolds, Monk, Berman, & Kupfer, 1989). Keysecondary outcome measures included other sleep-related data, such as sleep efficacy, total sleeptime, total wake time, and sleep quality. Study design (S): RCTs with meta-analyzable data. Casereports or series, qualitative reports, observational trials, nonrandomized studies, reviews, and meta-analyses were excluded. Studies conducted in patients with major medical conditions (e.g., cancer)were excluded.
Search methods
Both English (PubMed, PsycINFO, Embase, and Cochrane Library databases) and Chinese(WanFang, and CNKI) databases were systematically and independently searched by two
2 Y.-Y. WANG ET AL.
reviewers (YYW and FW), from their inception until August 16, 2017. The following searchterms were used: (“insomnia” OR “sleep” OR “early morning awakening” OR “maintenancedisorder” OR “dyssomnia” OR “sleepless”) AND (“mindfulness” OR “Mindfulness-BasedCognitive Therapy” OR “Mindfulness-Based Stress Reduction” OR “MBCT” OR “MBSR”)AND (“Random*” OR “control” OR “Randomized controlled trial”). Moreover, reference listsof the relevant reviews were hand-searched in order to avoid missing studies.
Data extraction
Two reviewers (YYW and FW) independently extracted the relevant data. Any inconsistency arisingin the process was discussed to reach an agreement or was resolved by referring to a third reviewer(YTX). Two studies reported both actigraphy and sleep diary data (Gross et al., 2011; Ong et al.,2014); in order to avoid interdependence, only actigraphy data were extracted. There was one study(Ong et al., 2014) with three treatment arms that compared the control group with two differentMBIs groups. Half of the participants in the control group were assigned to each MBIs arm to avoidinflating the number of participants in the control group.
Quality assessment
The quality of the included studies were assessed by the Cochrane risk of bias (Higgins &Green, 2014) and Jadad scale (Jadad et al., 1996), both of which are widely used qualityassessment tools for meta-analyses of RCTs. The Cochrane risk of bias assesses the aspectsof selection bias (random sequence generation and allocation concealment), reporting bias(selective reporting), blinding, attribution bias, and other sources of bias; while the Jadad scaleassesses the randomization, blinding, and withdrawals and dropouts of participants with thetotal score ranging from 3 to 4. Jadad total score < 3 was rated as low-quality; otherwise, it wasconsidered as high-quality (Jadad et al., 1996). The grading of recommendations assessment,development, and evaluation (GRADE) system (Atkins et al., 2004; Balshem et al., 2011) wasused to judge the evidence level of outcomes.
Data synthesis and statistical analyses
The Review Manager Version 5.3 (http://www.cochrane.org) and Comprehensive Meta-AnalysisV2.0 (www.meta-analysis.com) were used to synthesize data and conduct additional analyses.Considering the discrepancies in sampling methods, measurements, and demographic characteristicsbetween studies, the random effects model was used in all meta-analytic outcomes because it is moreconservative than the fixed-effects model (DerSimonian & Laird, 1986). Standardized mean differ-ence (SMD) with 95% confidence intervals (CIs) was used for continuous outcomes. Risk ratio (RR)± 95% CI was calculated for dichotomous data. Study heterogeneity was measured using I2, with I2
values greater than 50% indicating significant heterogeneity (Higgins, Thompson, Deeks, & Altman,2003). All meta-analytic outcomes were two-tailed, with significance level set at 0.05.
Results
Literature search and study characteristics
A total of 527 relevant hits were identified in the initial search. As shown in Figure 1, 5 RCTs with 11MBT treatment arms were included in the analyses. In Table 1, the pooled sample size was 520, with279 patients in the MBIs group and 241 in the control group. Study sites included China (3 RCTs,n = 436), the United States (2 RCTs, n = 84). The MBIs treatment duration ranged from 6 to8 weeks. One study in China used the CCMD-3 (Psychiatry Branch of the Chinese Medical
BEHAVIORAL SLEEP MEDICINE 3
Association, 2001), one study in China used DSM-IV (American Psychiatric Association, 1994),another study in Hong Kong used both DSM-IV (American Psychiatric Association, 1994) and ICD-10 (World Health Organization, 1992), and two U.S. studies used DSM-IV (American PsychiatricAssociation, 1994) and DSM-IV-TR (American Psychiatric Association, 2000). MBIs treatmentfrequency varied from 50 min per week for 6 weeks, to 2.5 hr per day for 8 weeks.
Assessment quality and quality of evidence
The risk of bias of the included studies is summarized in Supplemental Figure 1. Two RCTs weresingle blinded and all the others did not report blinding. Five RCTs described the random allocationsequence generation, and none mentioned allocation concealment. All studies were rated as low-riskin terms of attrition and reporting bias. Jadad scores ranged from 3 to 4 (Table 1). Of the 5 RCTs, allwere rated as high-quality. The quality of evidence of 5 outcome measures ranged from low-quality(80%) to moderate-quality (20%) according to the GRADE approach (Table 2).

Insomnia assessed by PSQI at post-MBI assessment
Three RCTs with 3 treatment arms reported data on insomnia assessed by the PSQI at the post-MBIsassessment. Compared to the control group, the MBIs group showed significant improvement inpost-MBIs insomnia (n = 247; SMD: −1.01, 95% CI: −1.28 to −0.75, I2 = 0%, p < 0.00001, Figure 2).
Sleep efficiency at post-MBIs assessment
Three RCTs with 4 treatment arms provided data on sleep efficiency, with 3 arms using actigraphy(Gross et al., 2011; Ong et al., 2014), and 1 arm using sleep diary (Wong et al., 2017). There was nosignificant group difference in terms of sleep efficiency at post-MBIs assessment (n = 274; SMD:−0.07, 95% CI: −0.31 to 0.17, I2 = 0%, p = 0.58).
Sleep time at post-MBIs assessment
Three RCTs with 4 treatment arms reported data on total sleep time (TST), with 3 arms using actigraphy(Gross et al., 2011; Ong et al., 2014), and 1 arm using sleep diary (Wong et al., 2017). There was nosignificant group difference in terms of total sleep time at post-MBIs assessment (n = 274; SMD: −0.14,95% CI: −0.51 to 0.24, I2 = 29%, p = 0.47). One RCT with 2 treatment arms also reported total wake timeat post-MBIs using actigraphy (Ong et al., 2014), and there was no significant group difference in termsof total wake time at post-MBIs assessment (n = 54; SMD: 0.03, 95% CI: −0.55 to 0.61, I2 = 0%, p = 0.92).

All cause discontinuation
The discontinuation rate was not significantly different between the MBIs and control groups(n = 536, RR = 3.74, 95% CI: 0.74 to 18.90, I2 = 35%, p = 0.11). Only 5 RCTs with 6 treatmentarms were included for primary and secondary outcomes, thus we cannot assess publication bias byperforming a funnel plot or Egger’s test (Egger, Davey Smith, Schneider, & Minder, 1997).
Discussion
This updated and comprehensivemeta-analysis of RCTs on the effect ofMBIs on insomnia found thatMBIssignificantly improved insomnia symptoms, as measured by the PSQI, compared to control groups. Inaddition, the discontinuation rate was not different between the MBIs and control groups, which indicatesthat the treatment adherence to MBIs was satisfactory.
Several meta-analyses have examined the effect ofMBIs on sleep. Onemeta-analysis (Kanen et al., 2015)evaluated the effect of MBIs on sleep disturbances in the general population. Two earlier meta-analysesincluded participants with major medical conditions, such as cancer and osteoarthritis (Gong et al., 2016;Kanen et al., 2015). In order to increase the homogeneity of included studies, we excluded studies thatincluded participants with major medical conditions and only synthesized studies that used insomniadiagnostic criteria. In addition, we included recently published RCTs in both English andChinese databasesthatwere not previously included. Similar to an earliermeta-analysis (Gong et al., 2016), we found thatMBIscould significantly improve insomnia symptomsmeasured by the PSQI. Themechanism of the therapeuticeffects of MBIs on insomnia is not clear, although it is recognized that MBIs could improve emotionalregulation and reduce stress level (Zhang et al., 2015), which could in turn alleviate insomnia. Furthermore,another meta-analysis (Kanen et al., 2015) reported that the significant effects of MBIs on insomnia werefound only in subjective (i.e., the PSQI) but not in objective assessments (i.e., actigraphy). In this study, nosignificant group difference was found in terms of actigraphy data as well as sleep efficacy and sleep time atthe post-MBIs. Instead of assessing individual sleep parameters, the PSQI covers multiple aspects of sleepincluding sleep efficacy, sleep time, sleep latency, and daytime dysfunction, which therefore may be moresensitive in detecting the minor changes in insomnia symptoms.
The advantages of this meta-analysis are the inclusion of recently published RCTs (Wei et al., 2017;Wong et al., 2017) and the exclusion of those involving major medical conditions, which provide a morehomogeneous sample and avoid the confounding effects caused by major medical conditions. However,there are also several methodological limitations. First, the duration and frequency of MBIs varied acrossstudies; the dose-response ofMBIs for insomnia was thus difficult tomeasure. Second, the follow-up periodranged from 3 to 6 months, but insufficient data were available to analyze the long-term MBIs effect oninsomnia. Third, both theMBIs and control groups were heterogeneous: theMBIs groups includedMBCT,MBSR, and mindfulness-based therapy for insomnia, while the control groups included wait-list control,pharmacotherapy, self-monitoring condition and regular health education, all of which increased theheterogeneity of the outcomes. Fourth, although all included studies were rated as high-quality, the qualityof evidence of 5 outcomemeasures ranged from low-quality (80%) to moderate-quality (20%) according tothe GRADE approach. Fifth, three of the five included studies were from China and two from the UnitedStates, which limits the generalization of the findings to other populations. Finally, theMBIs group includedMBIs alone or MBIs plus other treatments. Other treatments, such as health education, may haveaugmentation effect and bias the efficacy of MBIs in insomnia.
Conclusions
This comprehensive meta-analysis of RCTs on MBIs for insomnia found that MBIs appear to have apositive effect on insomnia as measured by the PSQI. Further RCTs with larger samples and longerfollow-up are needed to confirm the findings.
