Despite the popularity and prevalence of Employee Assistance Programs (EAPs), and the historical emphasis on how EAP can improve work performance, there has been very little rigorous evaluation of the workplace effects of EAP counseling. The aim of this Federal Occupational Health (FOH) outcome study was to examine if and to what degree EAP counseling is associated with improved workplace effectiveness with this particular population. Federal Occupational Health (FOH) is the largest provider of occupational health services in the Federal Government, serving more than 360 federal agencies and reaching 1.8 million federal employees. FOH began providing Employee Assistance Program (EAP) services in 1980 and is Health and Human Services’ recognized expert in this key area of employee health programs, delivering specialized EAP services exclusively to over 905,624 federal employees. In 2004 Selvick, Stephenson, Plaza and Sugden published one of the few studies that demonstrated statistically and practically significant outcomes from the FOH’s EAP. Their work showed significant improvement from pre- to post-EAP intervention on measures of productivity; work and social relationships; perceived health status; attendance and tardiness; and global assessment of functioning. In an effort to revitalize the findings with more current outcomes, FOH engaged an industry gold standard tool, the Workplace Outcome Suite (WOS). This measurement tool consists of a 5-item measure, that has been psychometrically tested and is also easy to administer telephonically. It consists of five scales that measures absenteeism, presenteeism, work engagement, life satisfaction, and workplace distress. In October of 2015 FOH began to collect data on specific outcomes for clients who accessed the EAP. This study reports findings from 2016 and 2017 data that indicates a significant decrease in absenteeism and workplace distress as well as increases in life satisfaction and workplace presenteeism.
