A confirmatory factor analysis of the evidence-based practice attitudes scale in child welfare

Despite the emphasis on evidence-based practice (EBP) in child welfare services (CWS) as an emerging and inevitable trend, implementation factors such as child welfare worker attitudes towards implementing EBP have received little attention in CWS. Aaron's (2004) Evidence Based Practice Attitudes Scale (EBPAS) has been used in multiple studies across mental health and healthcare settings. However, it has rarely been used in CWS. A-Mid Atlantic State implemented the EBPAS in all child welfare jurisdictions to measure workers' performance. The purpose of this study is to examine the EBPAS applied in a large urban child welfare services setting using a confirmatory factor analysis. Based on prior literature, three models were tested: a four factor model, a five factor model, and a second order four factor model. The second order model provided the best fit to the data, suggesting the EBPAS can measure workers' global attitudes, as well as four attitude types, towards EBP in a CWS setting. This study validates the use of the EBPAS with child welfare workers. Implications for effective evidence based practice in child welfare are discussed.
