Mindfulness Meditation for Chronic Pain: Systematic Review and Meta-analysis

BackgroundChronic pain patients increasingly seek treatment through mindfulness meditation.PurposeThis study aims to synthesize evidence on efficacy and safety of mindfulness meditation interventions for the treatment of chronic pain in adults.MethodWe conducted a systematic review on randomized controlled trials (RCTs) with meta-analyses using the Hartung-Knapp-Sidik-Jonkman method for random-effects models. Quality of evidence was assessed using the GRADE approach. Outcomes included pain, depression, quality of life, and analgesic use.ResultsThirty-eight RCTs met inclusion criteria; seven reported on safety. We found low-quality evidence that mindfulness meditation is associated with a small decrease in pain compared with all types of controls in 30 RCTs. Statistically significant effects were also found for depression symptoms and quality of life.ConclusionsWhile mindfulness meditation improves pain and depression symptoms and quality of life, additional well-designed, rigorous, and large-scale RCTs are needed to decisively provide estimates of the efficacy of mindfulness meditation for chronic pain.

A Systematic Review of Peer-Supported Interventions for Health Promotion and Disease Prevention

Prior research has examined peer programs with respect to specific peer roles (e.g.; peer support) or specific health/wellness domains (e.g.; exercise/diet), or have aggregated effects across roles and domains. We sought to conduct a systematic review that categorizes and assesses the effects of peer interventions to promote health and wellness by peer role, intervention type, and outcomes. We use evidence mapping to visually catalog and synthesize the existing research. We searched PubMed and WorldCat databases (2005 to 2015) and New York Academy of Medicine Grey Literature Report (1999 to 2016) for English-language randomized control trials. We extracted study design, study participants, type of intervention(s), peer role(s), outcomes assessed and measures used, and effects from 116 randomized controlled trials. Maps were created to provide a visual display of the evidence by intervention type, peer role, outcome type, and significant vs null or negative effects. There are more null than positive effects across peer interventions, with notable exceptions: group-based interventions that use peers as educators or group facilitators commonly improve knowledge, attitudes, beliefs, and perceptions; peer educators also commonly improved social health/connectedness and engagement. Dyadic peer support influenced behavior change and peer counseling shows promising effects on physical health outcomes. Programs seeking to use peers in public health campaigns can use evidence maps to identify interventions that have previously demonstrated beneficial effects. Those seeking to produce health outcomes may benefit from identifying the mechanisms by which they expect their program to produce these effects and associated proximal outcomes for future evaluations. PROSPERO REGISTRATION NUMBER Although we attempted to register our protocol with PROSPERO, we did not meet eligibility criteria because we were past the data collection phase.

A Cluster-Randomized Trial of Restorative Practices: An Illustration to Spur High-Quality Research and Evaluation

ABSTRACT Restorative practices in schools lack rigorous evaluation studies. As an example of rigorous school-based research, this article describes the first randomized control trial of restorative practices to date, the Study of Restorative Practices. It is a 5-year, cluster-randomized controlled trial (RCT) of the Restorative Practices Intervention (RPI) in 14 middle schools in Maine to assess whether RPI affects both positive developmental outcomes and problem behaviors and whether the effects persist during the transition from middle to high school. The 2-year RPI began in the 2014–2015 school year. The study’s rationale and theoretical concerns are discussed along with methodological concerns including teacher professional development. The theoretical rationale and description of the methods from this study may be useful to others conducting rigorous research and evaluation in this area.

How Community and Public Health Partnerships Contribute to Disaster Recovery and Resilience

OBJECTIVE To summarize ways that networks of community-based organizations (CBO), in partnership with public health departments, contribute to community recovery from disaster. METHODS The study was conducted using an online survey administered one and 2 years after Hurricane Sandy to the partnership networks of 369 CBO and the New York Department of Health and Mental Hygiene. The survey assessed the structure and durability of networks, how they were influenced by storm damage, and whether more connected networks were associated with better recovery outcomes. RESULTS During response and recovery, CBOs provide an array of critical public health services often outside their usual scope. New CBO partnerships were formed to support recovery, particularly in severely impacted areas. CBOs that were more connected to other CBOs and were part of a long-term recovery committee reported greater impacts on the community; however, a partnership with the local health department was not associated with recovery impacts. CONCLUSION CBO partners are flexible in their scope of services, and CBO partnerships often emerge in areas with the greatest storm damage, and subsequently the greatest community needs. National policies will advance if they account for the dynamic and emergent nature of these partnerships and their contributions, and clarify the role of government partners.

Systematic Reviews for Occupational Safety and Health Questions: Resources for Evidence Synthesis

This report outlines the steps undertaken in a systematic review of the literature to summarize the existing evidence to answer a research or policy question with a transparent, reliable, and valid approach. It provides practical guidance to execute systematic reviews as well as considerations and available resources specific to occupational safety and health evidence synthesis.

Combining Entrepreneurship and Web Development for High School Students: A Pilot Evaluation of the Startup Tech Program and High School Students' College and Career Aspirations

This pilot evaluation of Startup Tech — a program built around an innovative, applied curriculum that aims to teach creative problem-solving and technical skills in the context of developing and pitching a new web-based business idea — assesses whether 12th-grade students experienced either improved self-efficacy or changes in their college and career plans during the year in which they were in the program.

This systematic review assesses the safety and efficacy of mindfulness meditation as an intervention to alleviate chronic pain. The review will be of interest to military health policymakers and practitioners, civilian health care providers, and policymakers, payers, and patients. None of the authors has any conflicts of interest to declare. Abstract This systematic review synthesized evidence on mindfulness meditation interventions for the treatment of chronic pain (PROSPERO 2015:CRD42015025052). In June 2015, we searched four electronic databases, as well as bibliographies of existing systematic reviews, to identify randomized controlled trials (RCTs) testing the efficacy and safety of mindfulness to treat adults with chronic pain. Two independent reviewers screened identified literature using predetermined eligibility criteria, abstracted study-level information, and assessed the quality of included studies. Outcomes of interest included changes in pain symptoms, use of analgesics, health-related quality of life, and adverse events. Efficacy meta-analyses used the Hartung-Knapp-Sidik-Jonkman method for random-effects models. The quality of evidence was assessed using the GRADE approach. In total, 28 RCTs met inclusion criteria; three of these RCTs reported on safety. Interventions ranged in length from three to 12 weeks, and the median duration was eight weeks. We found low quality evidence (due to substantial unexplained heterogeneity among studies) that mindfulness meditation is associated with a small decrease in pain compared with control in 24
