Objectives: Mental health organizations are strongly encouraged to implement empirically supported treatments (ESTs), however little is known about their working environments. The present study investigated how provider demographics, workplace environment and whether ESTs were used affected the worker morale. Methods: Front-line workers (N = 1,273) from 55 different programs in a single, large organization completed a measure of organizational culture and climate (OCC) and worker morale. A multilevel regression analysis used worker demographics to predict worker morale at level 1 and EST use and OCC scales to predict program level worker morale. Results: Worker morale was significantly negatively correlated with EST use and significantly correlated with OCC dimensions. Regression results showed that culture and climate but not EST use predicted morale. Conclusions: Although EST use by programs in this agency had negative effects on both morale and OCC, separately, the effect on morale was subsumed by the effect on OCC
