Trial Information

Safety & Health Improvement: Enhancing Law Enforcement Departments

Following a 3 month pilot study with four teams, we will enroll 14 precincts and 80 teams
(approximately 470 participants) of LEO work groups for a prospective, clustered randomized
2-year assessment of the intervention (40 intervention and 40 testing-only,
control-condition teams). Participants will be evaluated at baseline, 12, and 24. Primary
study aims are; 1) Implement a randomized controlled efficacy trial of the SHIELD
intervention, a peer-led, team-based occupational wellness program, and assess its
behavioral and occupational outcomes, 2) Determine relations among variables in the chain
from exposure of LEO subjects to specific intervention components to changes in mediating
variables to behavior changes and occupational outcomes, and 3) Perform a cost analysis to
determine the economic benefit of this LEO worksite health promotion program.

The intervention involves a scripted peer-taught interactive curriculum, which is delivered
as twelve, one-hour weekly sessions incorporated into a team's usual work time activities,
with four follow-up booster sessions after twelve months. The curriculum is designed to
build understanding, healthy decision making skills and engender the social support of
teammates; its content and scope reflects the core lifestyles activities used with fire
fighters, along with adaptations for the needs of LEOs in domains of the team-building,
family support and psychological health.

Participant assessments include established survey instruments, physiological measures and
selected laboratory parameters of outcomes and potential mediating variables at the
individual, interpersonal and organizational levels. Intervention delivery and fidelity will
be assessed. Multilevel and latent growth modeling and mediation analyses will be used to
assess outcomes and the relationships among variables. At proposal completion there will be
an evidenced-based, exportable occupational safety and health program for LEOs. Its critical
components will be defined, and its benefits clearly determined.
