Objective: Confirm the Psychological Injury Risk Indicator (PIRI) scale capacity to facilitate routine assessment of psychological health of workers in high-stress environments.
Method: A cross-sectional study compared the PIRI scale scores with two experienced clinical psychologists' assessment of defined psychological injury in 93 participants. A second, longitudinal, study assessed PIRI predictive capacity for emotional exhaustion, physical health, and work engagement in 420 participants over 14 months.
Results: The PIRI scale was shown to (a) determine the degree of psychological injury in participants with high correspondence to a specialist clinical interview; and (b) predict future emotional exhaustion, physical health, and work engagement to a significantly better degree than the 12-item General Health Questionnaire and Kessler-10 measures.
Conclusions: The PIRI scale shows a valuable capacity to provide accurate routine psychological health assessment for at-risk workers in high-strain work environments.
