Recurrence of sickness absence; a longitudinal study

This thesis describes the risk of recurrence of sickness absence after a previous episode of sickness absence, not only recurrence after long-term sickness absence, but also recurrence after frequent episodes of short-term sickness absence. The main focus was on the recurrence of sickness due to common mental disorders (CMDs). Once there is a tendency towards sickness absence, will this eventually lead to long-term sickness absence? The results of our research seem to be confirmative.
