Objectives The present study was designed to test the demand-control model
using indicators of both health impairment and active learning or motivatio
n.
Methods A total of 381 insurance company employees participated in the stud
y. Discriminant analysis was used to examine the relationship between job d
emands and job control on one hand and health impairment and active learnin
g on the other.
Results The amount of demands and control could be predicted on the basis o
f employees' perceived health impairment (exhaustion and health complaints)
and active learning (engagement and commitment). Each of the four combinat
ions of demand and control differentially affected the perception of strain
or active learning. Job demands were the most clearly related to health im
pairment, whereas job control was the most clearly associated with active l
earning.
Conclusions These findings partly contradict the demand-control model, espe
cially with respect to the validity of the interaction between demand and c
ontrol. Job demands and job control seem to initiate two essentially indepe
ndent processes, and this occurrence is consistent with the recently propos
ed job demands-resources model.
