Repeated IT Interruption: Habituation and Sensitization of User Responses
Forthcoming in: Journal of Management Information Systems (VHB-JOURQUAL 3 Rating: A)

View Abstract
Information technology (IT) interruptions are IT-based events that capture users’ attention and interfere with other activities. This study focuses on repeated IT interruption and task performance. We draw on dual-process theory and suggest that users may get used to repeated IT interruption, known as habituation, or may become hypersensitive, known as sensitization. We validate the research model based on data from a laboratory experiment with 100 subjects by using a multivariate latent growth model (LGM). With subjective and objective measurement techniques, we show how users respond to repeated IT interruption with physiological arousal, psychological exhaustion, and behavioral task performance. Our results indicate that user responses follow different patterns over time, revealing time-dependent effects of arousal and exhaustion on task performance. We contribute to literature by providing evidence that repeated IT interruption results in unique habituation and sensitization user response patterns compared to a single IT interruption.

Technostress mitigation: an experimental study of social support during a computer freeze
Journal of Business Economics (JBE) (90:8), p.1199-1249, (VHB-JOURQUAL 3 Rating: B)

View Abstract
In situations when Information Systems (IS) do not work as intended, using IS might hinder their users and let them perceive technostress; this then comes along with reduced user performance and high perceptions of exhaustion, among others. To alleviate these consequences, a mitigating behavior of stressed users is to seek social support to get instrumental (e.g., from the help desk) or emotional (e.g., consolation) backing. Using insights from psychology literature that suggest social support reduces the consequences of stressors, this paper investigates how instrumental and emotional support reduces the consequences of techno-stressors, such as reduced end-user performance, techno-exhaustion, and physiological arousal, caused by techno-unreliability such as a computer freeze. In a laboratory setting, measurements of skin conductance were used to evaluate the technostress of 73 subjects, manipulated by techno-unreliability and then treated with instrumental and emotional support. The findings indicate that social support increased end-user performance as well as reduced techno-exhaustion and physiological arousal. In particular, instrumental support directly influenced end-user performance, techno-exhaustion, and physiological arousal, whereas emotional support only influenced techno-exhaustion. Further, this study provides the first indications that the effect of social support on technostress depends on individual differences.

IS Reappraisal and Technology Adaptation Behaviors: A Longitudinal Study During an IS Implementation
ACM SIGMIS Database (51:4), p.11-39, (VHB-JOURQUAL 3 Rating: B)

View Abstract
Employees have to adapt to newly implemented information systems (IS) because they are often perceived as radical changes or disruptions. To understand such adaptation behavior, IS research suggests that employees first appraise the new IS and second perform technology adaptive behaviors. However, while the psychology literature indicates that adaptation is a continuous process unfolding over time, previous IS literature treats adaptation towards IS implementation as a rather singular, noniterative process. As firms continue to implement IS, an understanding of reappraisal and the influence of technology adaptation behavior is vital to ensure successful implementations. Therefore, the present paper investigates reappraisal and the influences of four different technology adaptation behaviors. We conducted a longitudinal study and used hierarchical linear modeling (HLM) to validate our research model. The findings reveal that employees reappraise the newly implemented IS over time regarding perceived opportunity, threat, and controllability and demonstrate that technology adaption behaviors influence such reappraisal. One specific finding is that employees might get into positive or negative reappraisal loops. We thereby contribute to research by extending the adaptation behavior literature and add a new piece of the puzzle to understand how employees adapt towards newly implemented IS over time.

The Effects of Technostress and Switching-stress on Discontinued Use of Social Networking Services: A Study of Facebook Use
Information Systems Journal (ISJ) (25:3), p. 275-308, (VHB-JOURQUAL 3 Rating: A)

View Abstract
Although much research has been done on the adoption and usage phases of the IS life cycle, the final phase, termination, has received little attention. This paper focuses on the development of discontinuous usage intentions, i.e. the behavioral intention in the termination phase, in the context of social networking services (SNSs), where it plays an especially crucial role. We argue that users stressed by using SNSs try to avoid the stress and develop discontinuous usage intentions, which we identify as a behavioral response to SNS-stress creators and SNS-exhaustion. Furthermore, as discontinuing the use of an SNS also takes effort and has costs, we theorize that switching-stress creators and switching-exhaustion reduce discontinuous usage intentions. We tested and validated these effects empirically in an experimental setting monitoring individuals who stopped using Facebook for a certain time period and switched to alternatives. Our results show that SNS-stress creators and SNS-exhaustion cause discontinuous usage intentions, and switching-stress creators and switching-exhaustion reduce these intentions.
