This study constitutes the first national longitudinal survey to address the relationship between workplace harassment and service utilization. We examine how patterns of sexual harassment and generalized workplace harassment are linked to utilization of mental health, health, legal, spiritual, and work-related services, and whether and how gender influences these relationships. Data derive from a random digit dial telephone survey with a continental U.S. sample of employed adults. Eligibility criteria were being 18 years of age or over, and being employed at least 20 hours per week at some time in the 12 months prior to the wave 1 survey. Out of 4,116 households with eligible individuals, 2,151 agreed to participate at wave 1. 1,418 participated at wave 2, thus, the overall response rate was 34.5%. We show that the patterning of workplace harassment over two time points (chronic, remission, onset, never harassed) is associated with the use of different types of services. Gender partially moderated the relationship between workplace harassment and services.
