Theoretical perspective on the interplay between leT and quality of life Gunilla Bradley Royal Institute a/Technology, Stockholm, Sweden, BradlevrW.it.kth.se Abstract: An interdisciplinary research program on "Computer technology and work life" was initiated and led by the author at Stockholm University from 1974 to 1988. The program inspired many other research programs in Sweden in the field. A theoretical framework was developed including two theoretical models, one more general and one where the concepts and their interrelationships were specified. The models were tested empirically in three large work organisations in Sweden, representing three main historical periods of computer technology. It was also used as a model in discussing what might be desirable goals in the information society. The present fourth period, the "Network period", is characterised by a convergence of three main technologies: computer technology, telecommunication technology, and media technology (lCT). lCT is used in almost every activity and embedded in many things around us. The author proposes a superimposed theoretical model reflecting "ICT and psychosocial life environment", a revised model of her initial models. Finally, future research is discussed with reference to theoretical models revised, and conclusions address major psychosocial processes, psychosocial life environments and a call for synthesis.
