The research reported in this article intends to investigate whether individuals a) update degrees of beliefs over time and b) transfer behavioral intentions into adoption behavior in a different manner based on their personality. Therefore, the personality trait dispositional resistance is discussed within the Integrative Framework of Technology Use. Results of an empirical longitudinal analysis (N=145) show that individuals update their beliefs based on prior beliefs and usage behavior differently in accordance with their personality. Results also reveal that individuals transfer behavioral intentions into adoption behavior differently based on their personality. Hence, we discuss our contributions to technology adoption research by highlighting the importance of personality traits when investigating technology-related beliefs and behavior over time. Results also include an assessment of the findings' practical relevance by identifying which individuals maintain negative beliefs over time and by identifying the high extent of technology usage as a possibility for overcoming negative beliefs.
