RESUMEN
Implementation of evidence-based programs in progressed slowly, with the majority of services in child welfare settings lacking empirical evidence for effectiveness. In other settings, research has identified providers' attitudes about evidence-based practices (EBPs) as a potential barrier to adoption of EBPs. As little research has focused on the role of attitudes in influencing use after training in an EBP in child welfare, the potential for attitudes to impede implementation efforts in child welfare is unclear. This study addressed this question in a sample of 55 caseworkers and therapists randomly assigned to enhanced support to use an EBP following training or a training-only condition. Information on providers' use of the intervention after training and their attitudes about EBPs were measured for up to five time points. Results indicate that attitudes did not predict providers' use of the EBP, and attitudes did not change overall or in the enhanced condition that provided greater exposure to the intervention. Providers perceived of requirements to use a practice as more influential in their use than their openness to EBPs. However, those who were more open to EBPs were more likely to participate in implementation support after the training, suggesting that openness facilitates participation in activities that support use of a new intervention.
