Abstract Workaholism is a concept that needs conceptual and empirical clarification as it is currently defined, understood, and measured in different ways. Generally, positive workaholism features (e.g. work enjoyment) have consistently been shown to be positively related to good outcomes, whereas negative workaholism features (e.g. working compulsively) have been linked with negative outcomes. However, it should be debated whether workaholism should be considered as a multidimensional construct. This field is in great need of studies using longitudinal designs as well as studies including objective measures of behavior and health.
