This article presents an example of the successful adoption of workplace outcome measures in an internal employee assistance and work-life program at Partners HealthCare System. We present the findings for over 500 cases over a five-year span with data from the brief version of the Workplace Outcome Suite (WOS-5). This retrospective data analysis is significant for three reasons. First, most of the results in the literature to date for the WOS measures have been from the context of external vendors of EAP services whereas the present retrospective data analysis of Partners EAP is from the context of an internal EA program. Second, we also compare our results against a matched group of over 700 cases from other similar internal programs in the United States. These findings for internal programs are also compared with those of external EAP vendors in the United States. This is also one of the first reports to feature WOS results based on the simpler alternative scoring approach introduced in 2017 of having or not having a “problem” with each kind of workplace outcome.
