The internal structure of the Work

Personality-based integrity tests are used in selection procedures to reduce the chance of hiring employees who are likely to engage in counterproductive work behaviour. This study reports the internal psychometric properties of a personality-based measure developed for this purpose. Data collected from 1353 working adults were used to investigate the internal consistency reliability and to examine construct validity with confirmatory factor analysis and Rasch analysis. Results showed that the reliability estimates for all the scales of the assessment were satisfactory. For the confirmatory factor analysis, inspection of the incremental (comparative fit index and Tucker–Lewis index) and absolute (root mean square error of approximation) goodness-of-fit values found strong support for the construct validity of all the scales. Infit statistics from Rasch analysis provided further support for construct validity, with items from all the scales fitting the Rasch model. The confirmatory and Rasch analysis demonstrated that unidimensional, coherent, and meaningful latent constructs are being measured on the Work-related Risk and Integrity Scale. Overall, results found excellent support for the internal psychometric properties of the instrument in a culturally diverse context
