This study was designed to evaluate attitudes toward and utilization of evidence-based practices (EBPs) among mental health professionals specializing in trauma. An Internet survey was completed by 461 trauma professionals who were recruited via International Society for Traumatic Stress Studies membership rolls and electronic mailing lists of trauma special interest groups. Although a minority of participants held negative views of EBPs, the overwhelming majority of respondents were supportive of the EBP movement. Theoretical orientation, training model, and age were associated with EBP attitudes. Favorable EBP attitudes were not as strongly related to reported clinical behaviors as might reasonably be expected. Even respondents utilizing unsupported treatments espoused positive EBP opinions, suggesting that practitioners may hold widely varying evidentiary standards.
