Psychometric properties of heavy work investment measures: A systematic review

In recent years, the study of heavy work investment (HWI) has been diversifying greatly in the various fields of application in the organizational field, for example, occupational health, human resources, quality at work among others. However, to date, no systematic review has been carried out to examine the methodological quality of the instruments designed to measure HWI. Therefore, the present systematic review examines the psychometric properties of three main measures of HWI: Workaholism Battery (WorkBAT), Work Addiction Risk Test (WART), and Dutch Work Addiction Scale (DUWAS). Five electronic databases were systematically searched, selecting psychometric articles. Of the 2621 articles identified, 35 articles met all inclusion criteria published between 1992 and 2019. The findings indicated that most of the articles were focused on reviewing psychometric properties, analyses were conducted from classical test theory, collected validity evidence based on internal structure and relationship with other variables, and reliability of scores was obtained through the internal consistency method. Of the instruments reviewed, the DUWAS is the one with the highest methodological quality. Recommendations are made for future research to address the psychometric study of these instruments based on recent advances in the field of organizational measurement.
