Abstract

Inclusion criteria

Types of participants

This review will consider studies that include Registered Nurses, regardless of their credentials or specialty fields, who are currently employed in adult patient care settings. Studies involving nurses employed in non-adult health service settings will be excluded.

Types of intervention(s)/phenomena of interest

This review will consider studies that evaluate any mindfulness based programs that originate from the original Mindfulness-Based Stress Reduction Program developed by John Kabat Zinn.

The intervention will be compared to standard care, which in most instances is no intervention. Studies examining the effectiveness of mindful meditation alone without a concurrent structured mindfulness based program will be excluded.

Types of outcomes

This review will consider studies pertaining to mindfulness based programs that include the following outcome measure: perceived stress. Studies will be selected that measure stress experienced by nurses as measured by a variety of perceived stress scales, including but not limited to, the Perceived Stress Scale (PSS-14, PSS-10 and PSS-4) and the Depression and Anxiety Stress Scale (DASS-21).

Types of studies

This review will consider any experimental study design including randomized controlled trials, non-randomized controlled trials, quasi-experimental, and before and after studies for inclusion.

Search strategy

The search strategy aims to find both published and unpublished studies. A three-step search strategy will be utilized in this review. An initial limited search of PUBMED and CINAHL will be undertaken followed by an analysis of the text words contained in the title and abstract, and of the index terms used to describe the article. A second search using all identified keywords and index terms will then be undertaken across all included databases. Thirdly, the reference list of all identified reports and articles will be searched for additional studies. Studies published in English will be considered for inclusion in this review. Studies published since 1979 will be considered for inclusion in this review as the first mindfulness based stress reduction program was created in 1979 by John Kabat Zinn.

The databases to be searched include:

PUBMED

CINAHL

PsycINFO

Scopus

The search for unpublished studies will include:

Google Scholar

ProQuest Dissertation and Theses.

Initial keywords to be used will be:

Mindfulness; Nurses; Nursing; Stress; Stress reduction; Mindfulness based programs.

Assessment of methodological quality

Papers selected for retrieval will be assessed by two independent reviewers for methodological quality prior to inclusion in the review using standardized critical appraisal instruments from the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) (Appendix I). Any disagreements that arise between the reviewers will be resolved through discussion, or with a third reviewer.

Data extraction

Data will be extracted from papers included in the review using the standardized data extraction tool from JBI-MAStARI (Appendix II). The data extracted will include specific details about the interventions, populations, study methods and outcomes of significance to the review question and specific objectives. An attempt will be made to contact the authors of the primary studies for any missing information or to clarify unclear data.

Data synthesis

Quantitative data will, where possible, be pooled in statistical meta-analysis using JBI-MAStARI. All results will be subject to double data entry. Effect sizes expressed as odds ratio (for categorical data) and weighted mean differences (for continuous data) and their 95% confidence intervals will be calculated for analysis. Heterogeneity will be assessed statistically using the standard Chi-square. Where statistical pooling is not possible the findings will be presented in narrative form including tables and figures to aid in data presentation where appropriate.

Conflicts of interest

The authors have no conflict of interest to declare.
