This article describes the history, purpose, and overall methodology of the
Workplace Managed Care (WMC) study sponsored by the Substance Abuse and Me
ntal Health Services Administration, Center for Substance Abuse Prevention
(CSAP). This study was initiated to discern best practices for workplaces a
nd managed care organizations integrating their substance abuse prevention
and early intervention programs, strategies, and activities for employees a
nd their families. CSAP funded nine WMC grants to study their retrospective
and prospective data. Results of the WMC study suggested the addition of s
ubstance abuse prevention material to existing workplace health promotion o
fferings that resulted in improved substance abuse attitudes without jeopar
dizing existing health promotion programs. Stress management programming wa
s successful at improving substance abuse attitudes indirectly. This study
provides a platform for multidisciplinary research in workplace and managed
care settings.
