Doctoral thesis of Philosophy: The impact of disruptions on routinization of goal-directed grocery shopping behavior

This thesis bridges a gap in extant research by examining key factors that play a role in behavioral grocery shopping routines following minor and major disruptions. The present research involves two interrelated investigations incorporating mixed methodologies (Cresswell, 2003). The primary research objectives of the present thesis are: To model how consumer routines are established and maintained over time (i.e., model of routinization); and to investigate the impact of no, minor, and major disruptions on routinized grocery shopping behavior.
