Effects of Psychological Interventions for Mental Health in Police Officers: A Systematic Review and Meta-Analysis.
Review in Healthcare (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND/
objectivesPolice officers are exposed to chronic occupational stress and traumatic events, placing them at increased risk for mental health problems. Previous meta-analyses have been limited by heterogeneous samples and methodological variability. This study evaluated the effectiveness of psychological interventions on mental health and posttraumatic stress disorder (PTSD) symptoms among police officers using randomized controlled trials (RCTs).
methodsA systematic search of PubMed, Embase, Web of Science, PsycINFO, and MEDLINE was conducted for studies published between January 2000 and September 2025. The search strategy utilized key terms including "police officers," "psychological interventions," "mental health," and "randomized controlled trials". Only RCTs involving police officers were included. Psychological interventions were compared with waitlist, usual-care, or active control conditions. General mental health outcomes (depression, anxiety, and stress) were analyzed as the primary outcome, and PTSD symptoms as a secondary outcome. Effect sizes were calculated as Hedges's g using random-effects models. Subgroup, meta-regression, sensitivity, and publication bias analyses were conducted when appropriate.
resultsTen RCTs comprising 637 police officers met the inclusion criteria. Psychological interventions demonstrated moderate improvements in overall mental health (Hedges's g = 0.516, 95% CI = 0.296-0.735,
conclusionsThese findings suggest that structured psychological programs show potential to confer added benefits for general mental health beyond routine wellness activities, although the certainty of the evidence is moderate to low. In contrast, the evidence for PTSD symptoms remains inconclusive, with effects failing to reach robust statistical significance. This underscores that preliminary individual-level intervention may be insufficient for trauma-specific symptoms, necessitating further research into specialized, trauma-focused approaches and the role of organizational determinants in enhancing intervention efficacy.
