Using the data basis of the Mannheim Cohort Study the present paper investi
gates the correlation between socio-economic status and psychogenic impairm
ent due to predominantly psychosocially influenced ("psychogenic") disorder
s (neurotic spectrum disorders, personality disorders, stress reactions and
somatoform disorders) in a representative adult community sample. The peri
od of observation amounted up to 11,1 years. Subjects investigated within o
ur follow-up study for this interval (n=301) were drawn from an representat
ive adult community population sample (N=600). Within the three step class
model members of the lower class were at all investigation time points sign
ificantly stronger impaired compared to the members of the middle- and uppe
r class. Investigating the clinical impairment related to the intragenerati
ve class mobility those subjects, which could achieve a social rise between
two points of investigation were even prior, to the first investigation ti
me point, less affected compared to the ones remaining in their social clas
s. Vice versa subjects in the process of an social decline presented a stro
nger psychogenic impairment Drier to their decline compared to those, which
remained stable in their social class. These dynamic correlations offer ev
idence for the effect of the socalled "drift-hypothesis", which postulates,
that persons due to their disease decline in their social status respectiv
ely after improving rise to a higher social class.
