Effects of a Mindfulness-Based Intervention for Police Officers

Objectives Although the effectiveness of mindfulness-based intervention for various populations is well-documented, research examining these effects for police officers is limited. This study aimed to increase knowledge on (1) the effects of a mindfulness-based intervention in police officers and (2) potential mechanisms of change by relating changes in facets of mindful awareness to changes in stress. Methods In the present study, we investigated the effects of a 6-session group-based mindfulness-based intervention in police officers (n = 82) on self-report measures, using a quasi-experimental design consisting of a within-group 6-week baseline period; pre-test, 6-week intervention; and post-test, 6-week follow-up. Multilevel analyses were used to test intervention effects. Using structural equation modeling, we analyzed whether changes in facets of mindfulness were associated with changes in various types of stress. Results After the intervention, police officers significantly and substantially improved on stress (primary outcome), facets of mindful awareness (explanatory variables), and related secondary outcomes including somatic complaints, sleep disturbances, positive affect, happiness, and work ability, while in baseline period, outcome measures did not change. Effects remained significant or improved further during the follow-up period. Further, we found that increases in particularly the facets of mindful awareness of acting with awareness and non-judging were associated with reductions in stress. Conclusions Mindfulness-based intervention appears beneficial for police officers. Further, increases in both attention and acceptance skills such as acting with awareness and non-judging seem to be most important in explaining reductions of stress in police officers.
