Teleworking in the Covid-19 pandemic: The Effects of Life-Work Conflict on Job Outcomes and the Role of the IT Telework Environment
Forthcoming in: Business & Information Systems Engineering (BISE) (VHB-JOURQUAL 3 Rating: B)

View Abstract
Teleworkers who live and work in the same space are vulnerable to conflicts between personal life and work (LWC). The Covid-19 lockdowns increased the intensity and risk of LWC and changed telework conditions, confronting teleworkers with difficult personal situations and often ill-equipped telework environments. To develop a better understanding of the effects of different LWC dimensions (e.g., time, strain, behavior) on work exhaustion, job satisfaction, routine and innovative job performance and the role of the IT telework environment among teleworkers in the Covid-19 pandemic, we develop and validate a research model based on a sample of 249 teleworkers. Our findings show that LWC has adverse effects on job outcomes and that the IT telework environment moderates these effects. We contribute to the telework and role conflict literature by revealing the essential role of the IT telework environment and by differentiating between routine and innovative job performance among teleworkers.

Repeated IT Interruption: Habituation and Sensitization of User Responses
Journal of Management Information Systems (39:1), p.187-217, (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.

Social Networking Site Use Resumption: A Model of Return Migration
Journal of the Association for Information Systems (JAIS) (22:4), p.1037-1075, (VHB-JOURQUAL 3 Rating: A)

View Abstract
This research explains why individuals resume using social networking sites (SNSs) after terminating their use. Drawing on return migration theory, we developed a theory-driven model of SNS resumption that includes two novel antecedents of SNS resumption behavior: nonuse-related dissatisfaction and use-related satisfaction. We also hypothesize that dispositional resistance to change moderates the impact of nonuse-related dissatisfaction and use-related satisfaction on resumption. We used a mixed methods approach to refine and evaluate the research model. Study 1 used the critical incident method to identify SNS-specific antecedents of nonuse-related satisfaction and use-related satisfaction, allowing us to refine the research model. Study 2 used structural equation modeling to evaluate our research model using two three-wave surveys: one with recent ex-users who recently decided to stop using and delete their profiles on Facebook and one with long-standing ex-users who stopped using and deleted their profiles on Facebook a long time ago. We found support for most relationships in our model: nonuse-related dissatisfaction and use-related satisfaction drive resumption intentions, and dispositional resistance moderates these relationships. Furthermore, we found that the time elapsed since users discontinued Facebook moderated these relationships such that the effect of nonuse-related dissatisfaction on resumption intention is stronger for recent ex-users and the effect of use-related satisfaction is stronger for long-standing ex-users. Our findings advance the understanding of resumption, an understudied behavior of the IT lifecycle and IT use and acceptance research.

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.
