Background Resource and geographic barriers are the commonly cited constraints preventing the uptake of psychological treatment for chronic pain management. control, treatment Rabbit Polyclonal to NDUFA4L2 as usual or waiting list control conditions. This systematic review will be reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidance. Published and unpublished randomised controlled trials will be included and the literature search will comprise Ovid MEDLINE, Ovid Embase, PsycINFO and the Cochrane Library on Wiley, including CENTRAL and Cochrane Database of Systematic Reviews. Grey literature including theses, dissertations, technical and research reports will also be examined. Two review authors will conduct study selection, relevant data assessment and extraction of methodological quality. Threat of bias in included research will be assessed using the Cochrane Cooperation threat of bias device requirements. Two experienced coders will separately code behaviour modification techniques based on the behavior modification taxonomy (v1) of 93 hierarchically clustered methods and a book coding structure for setting of delivery and usability elements. A quantitative synthesis will be conducted if appropriate. Dialogue The findings of the review may give insight for health care professionals employed in chronic discomfort services also to researchers involved with designing and analyzing information and conversation technology-based interventions. Organized review enrollment PROSPERO CRD42016017657 Digital supplementary material The web version of the content (doi:10.1186/s13643-016-0350-1) contains supplementary materials, which is open to authorized users. beliefs that would enable its calculation. If lacking data necessary for analyses can’t be extracted from the scholarly research writer or extrapolated from various other figures, the scholarly study will be excluded. We will record the usage of intention to take care of analyses (ITT) and, if enough data is obtainable, we will carry out subgroup analyses to judge the impact of exclusion or inclusion of non-completers in final research analysis. We will record rates of lacking result data per arm and make reference to the Cochrane threat of bias tool for missing outcome data in any evaluation of imputation methods. Finally, we address the potential impact of missing data around the findings of the review in the Discussion section . Unit of analysis issuesWe anticipate unit of analysis issues such as repeated observations of the same outcome and studies including multiple intervention arms. For studies reporting repeated measurements of the same outcome, we will extract data at the following time points: baseline, post-treatment (not longer than 3?months post-randomisation) and follow-up (not buy RGD (Arg-Gly-Asp) Peptides longer than 12?months post-randomisation). For studies including more than two intervention groups, we will adhere to the recommended method suggested by the Cochrane Collaboration in section 16.5 for combining multiple groups from one study . If cluster-randomised controlled trials are included, we will check for unit of analysis errors. Where possible, we will recalculate results using the appropriate unit of analysis (Higgins 2011). As per the Eccleston et al., (2012) process, all psychological intervention circumstances will be labelled treatment and everything comparator circumstances will end up being labelled control circumstances. Evaluating for heterogeneityWe will assess heterogeneity buy RGD (Arg-Gly-Asp) Peptides by determining 2 and I buy RGD (Arg-Gly-Asp) Peptides 2 beliefs for all result factors. Statistical heterogeneity will be considered substantial if I 2 values are above 50?%. We will also assess the impact of heterogeneity through sensitivity analyses and presume the appropriate random-effects or fixed-effect model in meta-analyses accordingly . Assessment of reporting biasesAccording to section 10.1 of the Cochrane Handbook, reporting biases arise when dissemination of findings is influenced by the nature and direction of results . For this reason, we will, where possible, retrieve and compare the protocol for the included studies with the final reports. The potential for small study effects such as publication bias will be assessed visually by inspection of funnel plots of estimated effects by standard error and using statistical assessments which are in line with recent recommendations [66, 67]. Funnel plots will be assessed if 10 or even more research are identified. The possible known reasons for asymmetry will be investigated. Data synthesisWe shall pool data using the Cochrane Collaborations buy RGD (Arg-Gly-Asp) Peptides Review Supervisor Software program, RevMan 5.3 (RevMan 2014). A quantitative synthesis will end up being completed only when the included research are sufficiently homogenous with regards to quality, research design, individuals, buy RGD (Arg-Gly-Asp) Peptides interventions, type and final results of analyses to supply a meaningful overview of results. A narrative synthesis will be carried away when there is insufficient data to.
