Do I feel ill because I crave for work or do I crave for work because I feel ill? A longitudinal analysis of work craving, self-regulation, and health.

Background The theory of work craving defines workaholism as a pathological work addiction which comprises: (a) obsessive-compulsive desire to work, (b) anticipation of self-worth compensatory incentives from working, (c) anticipation of reduction of negative emotions or withdrawal symptoms from working, and (d) neurotic perfectionism. Research has shown that workaholism is associated with adverse health outcomes. However, the antecedents of workaholism and the causal direction of the relationship with health have been largely neglected. Aims In the present longitudinal study, we expect that work craving is predicted by deficits in emotional self-regulation (i.e., low action orientation) and mediates the relationship between self-regulation deficits and symptoms of psychological distress. We expected work craving to have an effect on later psychological distress symptoms, but not psychological distress symptoms to have an effect on later work craving. Methods In a sample of 170 German employees, a half-longitudinal design using two times of measurement was implemented to specify the paths of two different structural equation models of mediation: (a) action orientation to later work craving and work craving to later psychological distress, and alternatively, (b) the temporal order of action orientation to later distress and distress to later work craving. Results Our data indicated that work craving partially mediated the relationship between self-regulation deficits and psychological distress, but psychological distress symptoms were not found to increase later work craving. Conclusions The presented longitudinal study indicates important mechanisms of work craving, especially by highlighting the influence of self-regulation deficits on work craving and, in turn, psychological distress.
