The relationship between user participation and information systems su
ccess has intrigued researchers for two decades. Despite this history
there is minimal research on the antecedents of user participation. Th
e tenet of the present paper is that the conditions of user participat
ion are essentially changing. Especially, the European tradition of us
er participation has focused on blue collar workers rather than profes
sionals and managers. Users are normally assumed to be computer illite
rate. The North American tradition has almost exclusively focused on t
he impact of user participation on information systems success. The pr
esent paper examined the significance of organizational level of users
, their task variety and computer experience as determinants of user p
articipation including age, gender, education, computer training, orga
nizational tenure and job tenure as control variables. The three deter
minants were found to have a significant positive effect on user parti
cipation, computer experience emerging as the most dominant factor. Ge
nder, education and computer training were discovered to have signific
ant effects mediated by organizational level, task variety and compute
r experience.
