This paper explores which demographic variables (age, gender) correlate with presenteeism in research which aims to reproduce previous studies’ results. We aim to identify factors which may increase an individual’s susceptibility to presenteeism. This paper also introduces collectivism, a measure of one's self conception in relation to one’s ingroups, as a possible moderator of the relationship of age and gender on presenteeism. The thesis is that collectivism moderates certain demographic variables, strengthening their relationship to presenteeism. Participants worked more than 20 hours a week and responded to a 15 minute survey offered in Dutch and English. Data was analyzed with Pearson correlations, ANOVA and linear regression models in R Studio. Conclusions were that gender had a significant relationship with presenteeism and when collectivism is added to the regression equation this remains significant. The interaction effect of gender and collectivism had more of an impact on a woman’s presenteeism score, especially at lower collectivism scores. A high collectivism score for men resulted in increased presenteeism, and the opposite for women. Between age*collectivism and presenteeism no significant interaction was found.Show less
