Psychometric Validation of a Job-Related Mental Health Forensic Assessment Tool: Insights from the Chilean System

Keywords: Occupational health, mental health, exploratory factor analysis, reliability, occupational disorders

Abstract

The standardization of expert evaluations in occupational mental health is a global challenge. This study presents the psychometric validation of a support questionnaire for the Job Position Study for Mental Pathology (EPT-PM) in Chile, with potential transferability to other regulatory frameworks. A total of 326 applications were analyzed (295 valid after data cleaning) using Exploratory Factor Analysis (EFA) with a tetrachoric correlation matrix and Weighted Least Squares (WLS) estimation; reliability (KR-20, split-half) and diagnostic performance (ROC, AUC, sensitivity, specificity, accuracy) were estimated. The 8-factor solution explained 53% of the variance (RMSEA = .053, 90% CI [.048–.059]; TLI = .888; RMSR = .03), with high internal consistency (KR-20 = .91) and excellent discriminative capacity (AUC = .965; accuracy = .934). The findings support structural validity and diagnostic utility. The integration of psychometric evidence is suggested to improve forensic traceability, transparency, and comparability. A confirmatory study and the standardization of evaluator training are recommended.
