Purpose: the study aims to evaluate the concurrent validity of the shedler-westen assessment procedure (swap-200) and the millon clinical multiaxial inventory-iv (mcmi-iv) in a non-clinical sample from the iranian oil industry.methods and materials: the research utilized pearson’s product-moment correlation model to assess the relationship between the scales of the shedler-westen assessment procedure and the millon clinical multiaxial inventory-iv. the study sample consisted of employees from the iranian oil industry who participated in a psychological evaluation for managerial or contract promotion purposes.findings: the results demonstrated significant positive correlations between the scales of the swap-200 and the mcmi-iv, with correlation coefficients of 0.60 or higher at α = 0.01 and α = 0.05 levels. this indicates that both tools have strong concurrent validity in measuring personality disorders.conclusion: the study confirms that the shedler-westen assessment procedure and the millon clinical multiaxial inventory-iv exhibit concurrent validity in a non-clinical sample, supporting their effectiveness in assessing personality disorders in organizational contexts.
