Motivation and performance theories in organizational psychology tend
to have a predominantly individualistic scope, relating characteristic
s of individual tasks to personal work outcomes of individuals (e.g.,
the Job Characteristics Model [JCM]). The present study goes beyond th
e realm of individual job characteristics by examining the effects of
two interpersonal characteristics: task and outcome interdependence of
team members. Subscales for the measurement of these social job dimen
sions were developed. The results support the hypothesis that, in addi
tion to the JCM variables, the interdependence dimensions influence th
e employees' sense of responsibility and personal work outcomes. More
specifically, the interdependence dimensions influence experienced res
ponsibility for the others' work and thus account for a separate part
of the variance in team members' personal work outcomes.
