| Sumario: | <p>This mixed-methods randomized controlled trial study, conducted in collaboration with three Dane County (Wisconsin) law enforcement agencies, compared the effects of an 8-week mindfulness training (MT) program relative to a waitlist control (WLC) group on biological, behavioral, and self-report measures of stress and stress-related health outcomes. Across a two-year data collection period, the research team randomly assigned 114 sworn law enforcement officers to MT or WLC groups. Across three timepoints (baseline, post-program, and 3-month follow-up), researchers assessed the impact of MT on perceived stress (Aim 1), physical and mental health outcomes including behaviorally assessed and self-reported sleep quality, cardiovascular risk factors, and symptoms of PTSD, anxiety, and depression (Aim 2), and stress-related biological and behavioral markers (Aim 3), including cortisol output and a behavioral assay of hippocampus function. Data collected as part of this study include quantitative measures obtained during laboratory visits and a week of field data collection, as well as optional semi-structured qualitative interview data.</p> <p>This collection currently contains the following file types available in zipped package format. Excluding changes made for confidentiality purposes, files have been released as they were received by ICPSR: <ul> <li>Summary data: Master data file (nij_masterfile.csv) containing demographics, summed scores from self-report questionnaires, behavioral markers, biomarkers, and mindfulness practice logs; Fitbit activity, heart rate, and sleep data (nij_fitbitSummary.csv); saliva sample collection data (nij_salivaCollectionNotes.csv, nij_salivaQCSpreadsheet.xlsx, nij_salivaryCortCleaned.csv, nij_salivaryCortProcessed.csv, nij_salivaryCortRaw.csv); work event log data (nij_workEventsRaw.xlsx)</li> <li>Raw behavioral data files: for all timepoints, affective go/no-go task data (agnRaw) and mnemonic similarity task data (mstRaw)</li> <li>Summary behavioral data files (agnSummary): for all timepoints, affective go/no-go task data</li> <li>Raw Fitbit data files (fitbitRaw): activity/steps, heart rate, and sleep data for all timepoints</li> <li>Scripts: R, Python, and bash scripts, with readme files, that were used in biomarker and behavioral marker data cleaning/analysis</li> </ul></p> <p>Qualitative interview data and documentation are not available at this time.</p>
