The purpose of this article is to report on the use of empirically supported treatments (ESTs) among clinical addiction workers, in order to relate the use of ESTs to both perceived agency expectations and worker-level attitudes. We recruited a convenience sample of 120 frontline workers within 4 agencies providing addiction services in St. Louis. The results found that agency expectations were related to clinician's reported use of ESTs, but were unrelated to clinician attitudes. The regression results revealed that reported use of ESTs was associated with openness to ESTs, but was not associated with favoring clinical experience. Organizational leaders interested in using ESTs should send clear, strong messages that they expect workers to use ESTs during clinical practice. (PsycINFO Database Record
