Although I am stressed, I still use IT! Theorizing the decisive impact of strain and addiction of social network site users in post-acceptance theory

This paper examines the decisive roles of strain and addiction in post-acceptance behavior of social networking sites' users. Therefore, we focus in a first step on the formation of discontinuous usage intentions by theorizing strain, addiction, and satisfaction as direct influencing factor that causes and/or inhibits them. In a second step, the influence of these variables on the intention-behavior relation is focused. We theorize that addiction as well as the ratio between satisfaction and strain moderate whether users transfer discontinuous usage intentions into non-usage behavior. To validate the subsequent research model we propose a longitudinal research setting and present initial results, whereupon satisfaction and strain - but not addiction - causes discontinuous usage intentions. We discuss our expected contributions by revealing that satisfaction, strain, and addiction influence whether a technology is used continuously; however, their influence on intentions and actual behaviors differs.
