Given the need to develop and validate effective implementation models that lead to sustainable improvements, we prospectively examined changes in attitudes, behaviors, and perceived organizational support during and after statewide Community-Based Learning Collaboratives (CBLCs) promoting trauma-focused evidence-based practices (EBPs). Participants ( N  = 857; i.e., 492 clinicians, 218 brokers, and 139 senior leaders) from 10 CBLCs completed surveys pre- and post-CBLC; a subsample ( n  = 146) completed a follow-up survey approximately two years post-CBLC. Results indicated (a) medium, sustained increases in clinician-reported use of trauma-focused EBPs, (b) medium to large, sustained increases in perceived organizational support for trauma-focused EBPs, and (c) trivial to small, sustained increases in perceived organizational support for EBPs broadly. In contrast, clinician-reported overall attitudes towards EBPs decreased to a trivial degree pre- to post-CBLC, but then increased to a small, statistically significant degree from post-CBLC to follow-up. Notably, the degree of perceived improvements in organizational support for general and trauma-focused EBPs varied by professional role. Findings suggest the CBLC implementation strategies may both increase and sustain provider practices and organizational support towards EBPs, particularly those EBPs a CBLC explicitly targets.
