Recent research suggests that psychological needs such as competence and relatedness are involved in users’ experience with technology and are related to the perception of a product's hedonic and pragmatic quality. This line of research, however, predominately focuses on positive leisure experiences, and it is unclear whether need fulfillment plays a similar role in negative experiences or in other activity domains such as work. Therefore, this study investigates need fulfillment in positive and negative experiences, and in work and leisure experiences in two separate studies by analyzing almost 600 users’ experiences with technology along with ratings on need fulfillment, affect, and perceived product quality. Results suggest that work and leisure experiences as well as positive and negative experiences differ in terms of need fulfillment. Hence, both activity domain and valence of experiences are important factors that should be taken in account when modeling user experience.
