Based on Bayer and Gerstein's (1988a) Bystander- Equity Model of Supervisory Helping Behavior, this study examined the relationship between characteristics of EAPs, managers, workers, and the EAP referral process. In general, it was hypothesized that managerial status, the type of employee substance abuse, and the location of an EAP would affect hypothetical supervisors' referrals. Graduate level business students (n = 222) were asked to imagine themselves as supervisors (upper, middle, and front-line) of persons employed by a fictitious manufacturing firm. Each received one of three sets of employee scenarios (cocaine abuser, alcohol abuser, or job-impairment only). Additionally, half of the particiants were told that their EAP was company-based, while the other half were told that their EAP was community-based. Respondents were asked to indicate their likelihood (0%-100%) of referring a particular worker to their EAP. As expected, ANOVA results revealed two main effects for type of substance abuse and managerial level. Participants were more likely to refer cocaine abusers than alcohol or non-substance abusing hypothetical employees. Referral rates were also higher for alcoholl abusers as compared to non-substance users. Finally, it was discovered that hypothetical front-line managers were more inclined to make referrals as contrasted with upper-level managers. No effect was discovered for the manipulation of the EAP's location. A number of theoretical explanations for these results were offered, as were limitations of the current study and implications for future research.
