In the research into subjective strain there does not exist yet an uni
versally accepted definition; the existing theoretical models consider
its complex structure as related to variables that influence its char
acteristics not enough. On the basis of the results of analysing numer
ous definitions and models of subjective strain a re-definition of emo
tional and cognitive component was done and the existing idea about th
e relation between actual and habitual aspects of subjective strain wa
s re-evaluated. A model of subjective strain was presented that holds
emotions, physical feelings and ''emotionally neutral periods'' as pri
mary units of analysis for its structural components. The model consid
ers the process character of subjective strain and respects the existe
nce of actual subjective strain as strain in a period of time, and hab
itual subjective strain as strain typical for the individual. The mode
l integrates factors participating in the determination of the subject
ive strain and classifies them into four groups: variables of the envi
ronment, variables related to the individual, variables of moderating
type, and variables of mediating type.
