Work-related psychological trauma: A review of methodological and assessment issues

Abstract
The members of many professional and occupational groups (e.g., emergency services, social services, psychology, and financial sector) can become affected by traumatic events occurring in the workplace. Currently, a range of methodologies and assessment instruments are used in the study of this area, making comparison between studies difficult, and raising issues relating to the validity and reliability of the instruments. Existing research in this area is also hampered by it being predominantly cross‐sectional in nature. This paper discusses the issues that need to be dealt with in order to put the study of work‐related psychological trauma on a firm theoretical foundation. The issues canvassed include establishing assessment instruments using sound psychometric principles: the need for normative data: the methodological implications of longitudinal, multi‐wave research design; and evaluating change.
