Objective: To study how common personality disorders (PDs) are among employed subjects with first-episode depression. Depression is the single most common cause of working disability in Finland. Personality disorders are associated with depression.
Methods: Subjects were screened using the Beck Depression Inventory scale, with a cutoff point greater than 9. The structured clinical interview for Diagnostic and Statistical Manual, fourth revision, was used to assess mental disorders. Inclusion criterion was major depressive disorder.
Results: Most of the 272 participants were female (83%) and the majority (74%) were older than 40 years. The main finding was that one third of the participants had obsessive-compulsive PD. The prevalence of obsessive-compulsive PD was 50% among men and 28% in women.
Conclusion: It is important to recognize comorbid PDs when assessing working-age persons experiencing depression.
