Mental and behavioural disorders (ICD-10 F00-F99, Z502, Z503, Z561-Z566, Z630-Z639, Z729, Z733, Z738, Z864, Z915): schizophrenia, mood disorders, stress-related disorders and mental and behavioural disorders due to psychoactive substance useDisability free days=number of between end of first episode and beginning of subsequent episodeNumber of employees with
≥1 sickness absence episode:
Due to mental disorders=422
Due to physical disorders=
3171
Median disability free days (SE):
Previous episode for mental disorders=673 (79.8)
Previous episode for physical disorders=1053 (48.6)
Koopmans et al9NLCommon mental disorders (CMD) from medical certification: stress-related (distress and adjustment disorders) (ICD-10 R45, F43) and psychiatric (mild to moderate depressive and anxiety disorders) (ICD-10 F32.0, F32.1, F40.0, F40.1, F40.2, F41.0, F41.1, F41.2, F41.3)Recurrence density=number of employees with recurrent episodes by the worker-years in the subpopulation of men and women with a previous episode of sickness absence due to a CMD
New episodes=>28 days apart
Worker-years=years of coverage from index episode to end of employment period
Number of employees with ≥1 sickness absence due to CMD=8951
Total number of sickness absence due to CMD=10 921
From 2001 to 2007, episodes per worker with ≥ 1 sickness absence related to CMD:
1 episode = 82%
2 episodes= 14%
3 episodes= 3%
≥ 4 episodes = 1%
From 2001 to 2007, CMD recurrence densities/1000 worker-years (95% CI):
Men:
Stress=74.4 (72.9 to 76.0)
Psychiatric=83.8 (71.9 to 95.7)
Total CMD=75.6 (70.7 to 80.4)
Women:
Stress=78.4 (75.9 to 80.9)
Psychiatric=78.9 (64.1 to 93.7)
Total CMD=78.5 (72.4 to 84.6)
From 2001 to 2007, CMD sickness absence median time to onset recurrence (in months) (95% CI):
Men:
Stress=11 (11 to 13)
Psychiatric=12 (8 to 15)
Total CMD=11 (10 to 13)
Women:
Stress=11 (9 to 12)
Psychiatric=10 (8 to 12)
Total CMD=10 (9 to 12)

Worker-years=years of coverage from index episode to end of employment period
Number of employees with ≥1 sickness absence due to CMD=9904
Total number of sickness absences due to CMD=12 404
From 2001 to 2007, CMD sickness absence median time to onset recurrence (in months) (95% CI):
Total=10 (10 to 11)
Distress symptoms=11 (10 to 12)
Adjustment disorder=11 (9 to 12)
Depressive symptoms=10 (7 to 12)
Anxiety symptoms=10 (7 to 14)
Other CMD disorders=8 (6 to 9)
Reis et al11BRMental and behavioural disorders (ICD-10 F00-F99)Duration of episode=Number of calendar days absent from work
Recurrence density=number of recurrent sickness absences divided by total worker-time at risk for the subsequent sickness absences
Number of sickness absence episodes:
Due to any disorder=5138
Due to mental and behavioural disorders=324
Recurrence density/100 worker-months:
Due to any disorder =17.37
Due to mental and behavioural disorders=6.72
Roelen et al10NLMental and behavioural disorders from medical certification (ICD-10 F00-F99)
Recurrence density=number of employees with recurrent episodes by the worker-years in the subpopulation of men and women with a previous episode of sickness absence
Number of employees with ≥1 sickness absence=36 342
Number of employees with ≥1 sickness absence due to mental and behavioural disorders=7197
Number of employees with >1 sickness absence due to mental and behavioural disorders=1400
Worker-years=363 461
From 2001 to 2007,
Recurrence density/1000 worker-years (95% CI):
Mental and behavioural disorders=80.4 (74.9 to 86.0)
Any disorder=81.6 (79.1 to 84.0)
Median days to recurrence (in days) (95% CI):
Mental and behavioural disorders=328 (284 to 372)
Any disorder=384 (367 to 401)
