ADHD and its Effects on Job Performance: A Moderated Mediation Model

The purpose of the present study was to examine the effects of ADHD on job performance and the possible mediating role of work engagement and moderating role of gender. Hypotheses testing were performed using structural equation modeling base on PLS-SEM approach applied to a sample of 448 employees from different organizations in Puerto Rico. The results shown that ADHD has a direct effect on task performance and counterproductive work behaviors, but none on organizational citizenship behaviors. Meanwhile, the relationship between ADHD and task performance/organizational citizenship behavior were mediated by work engagement. On the other hand, gender moderated the relationship between ADHD and counterproductive work behaviors on which males were more strongly to show counterproductive work behaviors under high levels of ADHD than females. Findings are discussed in the light of their theoretical and practical implications for future studies.
