The interpersonal sensitivity/privileged self scale (IPS) was developed to measure the personality traits assumed to be risk factors for depression, especially "modern type depression (MTD)". Although MTD has become a subject of discussion in corporate organizations, previous studies using the IPS sampled only college students. Therefore, we examined the relationship between IPS scores and depressive symptoms in company employees via an online survey. Participants were 518 (258 male, 260 female) Japanese employees, aged 20-59 years (M = 37.39, SD = 11.17). They completed the IPS and a depression scale (Kessler-10), and reported their socioeconomic status. To compare IPS scores between generations, we divided participants into four groups by age (10-year intervals). The results showed that IPS scores were (1) almost unchanged across age groups and (2) positively correlated with depression symptoms. We discuss these results with respect to participants' socioeconomic status.
