Confirmatory Factor Analysis of the Evidence-based Practice Attitude Scale (EBPAS) in a Geographically Diverse Sample of Community Mental Health Providers

Abstract

The Evidence-Based Practice Attitude Scale (EBPAS) assesses mental health service provider attitudes toward adopting evidence-based practices. The original scale development was done in one large California County using paper/pencil surveys. The present study examined the factor structure and internal consistency of the EBPAS in a sample of service providers from 17 states. Participants were mental health workers from agencies affiliated with communities funded under the federal Comprehensive Community Mental Health Services for Children and Their Families Program. A confirmatory factor analysis supported the originally derived a priori factor structure of the EBPAS in this new more geographically diverse sample and with a different data collection method. Analyses also demonstrated better internal consistency than in the original psychometric analyses. This study supports the factor structure and reliability of the EBPAS.
