Mental disorders are particularly stressful in combination with unemployment. Unemployed are often in a worse physical condition compared to employed people; they tend to negative emotional states and depression, fatigue and sleep disorders. It is to be expected that unemployment will have the same effect on adolescents. Fergusson, Horwood and Lynskey (1997) showed that in 16 to 25 years old, the increase of the unemployment was correlated with the increase of mental distress having consequences like depression, anxiety, substance abuse and attempts to suicide.
