Vicarious Trauma Scale: Psychometric Properties in a Sample of Social Workers from Spain.

As a result of secondary exposure to traumatic material, social workers may experience vicarious trauma. However, the analysis of this variable among social workers is scarce. The Vicarious Trauma Scale (VTS) is a brief instrument designed to measure the stress consequence of shared trauma. This study aims to examine the psychometrics of the VTS in a sample of 448 social workers from Spain. The results from the exploratory and confirmatory factor analyses (EFA and CFA) indicated that the VTS has satisfactory psychometric properties. Different indices of internal consistency supported the reliability of the VTS. Both EFA and CFA revealed the existence of two factors, corresponding to the cognitive and affective consequences of secondary exposure to trauma. Finally, the correlations of the VTS with other relevant and well-known job variables (workload, work-family conflict, detachment, supervisor support, burnout, and engagement) followed the expected pattern, and the VTS differentiated the social workers by their trauma caseload. Therefore, the VTS can be considered an adequate screening method of social workers' vicarious trauma, and its application recommended to examine the possible risk and protective factors and consequences.
