The dark side of working online

Ivana Vranjes; Elfi Baillien; Heidi Vandebosch; Sara Erreygers; Hans De Witte

The introduction of new technologies created avenues for new forms of bullying. Despite an impressive body of research on cyberbullying amongst youngsters, studies in the work context have largely neglected its electronic counterpart. In this study, we define workplace cyberbullying and propose an Emotion Reaction Model of its occurrence. Our model aligns with the main proposition of the Affective Events Theory (Weiss & Cropanzano, 1996), that emotions evoked by certain work events may fuel emotion driven behaviors. However, in our model these relationships are further specified combining different literature traditions. Making inferences from the workplace bullying literature, we suggest work stressors to be the work events leading to cyberbullying. Furthermore, building on the literature on cyberbullying amongst youngsters, computer-mediated communication and emotions, we propose discrete emotions of anger, sadness and fear to play a significant role in explaining this stressor-cyberbullying relation. In addition, different moderators (i.e., control appraisal and emotion regulation) of this relationship are suggested and implications of the model are discussed. The concept of workplace cyberbullying is defined.A theoretical model of factors predicting workplace cyberbullying is proposed.Both victimization and perpetration of workplace cyberbullying are accounted for.Discrete emotions are seen as drivers of cyberbullying behaviour.

Moon and media : lunar cycles and television viewing

Heidi Vandebosch; Keith Roe; Jan Van den Bulck

A review of the literature reveals that the possibility of lunar influence on various aspects of human health and behavior has long been taken seriously in established scientific journals. The purpose of this article is to extend this perspective to media research by focusing on the relation between lunar cycles and television viewing behavior. In preliminary analyses performed on a data set containing daily television viewing figures and moon and weather information for Flanders in 1993 (over a 12-month period), a weak but significant positive relation between the amount of television viewing and the percentage of the moon illuminated was found. However, subsequent analyses of a data set containing daily television viewing figures and moon information for Flanders, Denmark, Norway, and The Netherlands in 2002 (over a 12-month period), revealed a weak positive correlation between television viewing time and percentage of the moon surface illuminated only in Denmark. Given these inconsistent results, it is concluded that further investigation is needed. Future studies should investigate data over a longer period of time, include additional moon variables (i.e., amount of moonlight), explicitly test the moon-sleep deprivation-television viewing hypothesis, control for other environmental factors (e.g., weather conditions), and search for alternative explanations for a possible relation between amount of television viewing and the moon cycle.

Nice or Naughty? The Role of Emotions and Digital Media Use in Explaining Adolescents’ Online Prosocial and Antisocial Behavior

Sara Erreygers; Heidi Vandebosch; Ivana Vranjes; Elfi Baillien; Hans De Witte

The opportunities and mostly the risks of digital communication technologies for adolescents have been documented extensively in the last two decades, but less is known about how adolescents interact with each other online, especially regarding positive interactions. Moreover, since online prosocial and antisocial behavior have rarely been assessed simultaneously, it is hard to obtain a balanced view of adolescents’ online behavior. Therefore, in this study, we examined both dimensions of online social behavior and how these are related to adolescents’ experienced emotions and their uses of digital media. Findings indicated that participants performed and received more prosocial than antisocial behavior online. Experiencing negative as well as positive emotions was related to online social behavior, and these associations were mediated by adolescents’ use of social and audiovisual media, but not by gaming or functional Internet use. The social sharing of emotions and mood management theory are used to discuss the results.

When workplace bullying goes online: construction and validation of the Inventory of Cyberbullying Acts at Work (ICA-W)

Ivana Vranjes; Elfi Baillien; Heidi Vandebosch; Sara Erreygers; Hans De Witte

ABSTRACT There has been an increase in the use of Information Communication Technologies in the workplace. This change extends the scope of bullying behaviours at work to the online context. However, a generally accepted measure of workplace cyberbullying is still lacking. The purpose of the present paper is to construct and validate the Inventory of Cyberbullying Acts at Work, in order to contribute to this emerging field. Building on existing knowledge, we expected three types of cyberbullying behaviours to emerge in the work context: person related, work related and intrusive. First, the items of the scale were constructed and the three-dimensional structure of the scale was tested in two different samples. Then, the reliability and the convergent validity of the scale were assessed. Finally, we tested the predictive validity of the scale by assessing the impact of exposure to cyberbullying acts at work to individuals’ mental well-being six months later. Our analyses confirmed the three-dimensional structure of the scale. In addition, the scale was found reliable and valid. The construction of this scale offers an avenue for further research on cyberbullying in the work context.

Positive or negative spirals of online behavior? Exploring reciprocal associations between being the actor and the recipient of prosocial and antisocial behavior online:

Sara Erreygers; Heidi Vandebosch; Ivana Vranjes; Elfi Baillien; Hans De Witte

Bidirectional associations between being cyberbullied and cyberbullying others have been suggested, as well as bidirectional patterns of online prosocial behavior (reciprocity). However, so far, these relations have been studied as population-level associations, and it is not clear whether they also reflect within-person behavioral patterns. Therefore, this study aimed to disentangle between-person and within-person processes in online antisocial (cyberbullying) and prosocial behavior over time. Random intercept cross-lagged panel models were used to examine long-term within-person patterns of involvement in cyberbullying and online prosocial behavior. The findings showed no within-person effects between cyberbullying victimization and perpetration over time. In contrast, results did reveal significant within-person autoregressive effects of performing and receiving online prosocial behavior over time, and within-person cross-lagged effects between receiving online prosocial behavior and acting prosocially later on. These results indicate long-term positive, reinforcing spirals of prosocial exchanges, but no long-term negative spirals of cyberbullying perpetration and victimization.

Shall I call, text, post it online or just tell it face-to-face? How and why Flemish adolescents choose to share their emotions on- or offline

Anne Vermeulen; Heidi Vandebosch; Wannes Heirman

Abstract Social sharing of emotions is a frequently used emotion regulation strategy. This study adds to the emotion regulation literature and the affordances of technologies perspective by providing a better understanding of with whom adolescents share emotions on- and offline, how they do this and why they use certain modes. In-depth interviews with 22 Flemish adolescents (aged 14–18) show that these youngsters share almost all experienced emotions, often with multiple recipients and using multiple communication modes. Although they mostly prefer sharing emotions face-to-face, they also share by texting, calling, or posting something on Twitter, Facebook, Snapchat, or Instagram. Our respondents generally make a more or less conscious decision about what and how to share. The valence, type, and intensity of the emotion, the affordances of the mode, social norms, and impression management concerns influence this decision.

Development of a measure of adolescents’ online prosocial behavior

Sara Erreygers; Heidi Vandebosch; Ivana Vranjes; Elfi Baillien; Hans De Witte

ABSTRACT Research on adolescents’ media use has focused predominantly on its negative aspects (risks) and far less on its positive side (opportunities). This is reflected in the lack of validated instruments to assess adolescents’ online prosocial behavior. To address this issue, we developed the Online Prosocial Behavior Scale (OPBS) to assess adolescents’ involvement in online prosocial behavior. Two subscales (performing and receiving online prosocial behavior) were constructed and their factor structure was evaluated and confirmed through parallel analysis, exploratory factor analysis, and confirmatory factor analysis. The OPBS-subscales displayed good reliability and correlated positively with offline prosocial behavior and use of digital media, supporting the scale’s construct validity. Unexpectedly, the subscales also correlated positively with online antisocial behavior, which may be understood within the framework of the online disinhibition theory. The scale can be a useful tool for researchers and practitioners who need a global instrument to assess adolescents’ online prosocial behavior.

The Longitudinal Association Between Poor Sleep Quality and Cyberbullying, Mediated by Anger

Sara Erreygers; Heidi Vandebosch; Ivana Vranjes; Elfi Baillien; Hans De Witte

ABSTRACT Adolescents tend to go to bed later and sleep less as they grow older, although their need for sleep stays the same throughout adolescence. Poor sleep has negative consequences on personal and interpersonal functioning, including increased aggressive tendencies. With adolescents’ social life increasingly including interactions via digital media, these interactions may also become more aggressive when adolescents’ sleep problems increase. One of the ways in which online aggression may be enacted is through cyberbullying. Although previous research has examined the role of sleep disruptions in offline bullying, the role of sleep in cyberbullying has not yet been addressed. Therefore, this study examines the longitudinal effect of poor sleep quality on later cyberbullying behavior. Thirteen- to fourteen-year-old adolescents completed self-report measures on sleep quality, anger, cyberbullying perpetration, and frequency of digital media use. Because one of the pathways through which sleep is proposed to be linked to aggression is an affective pathway, namely via angry affect, a mediation model of poor sleep quality predicting cyberbullying via feelings of anger was tested. Results from structural equation modeling and a bootstrap test indicated that poor sleep quality was indeed indirectly associated with later cyberbullying behavior through heightened feelings of anger, even when taking the effects of the use of digital media and previous cyberbullying behavior into account. This finding provides support for the proposed affective pathway linking sleep problems to aggression. As sleep problems and anger seem to play a predicting role in cyberbullying behavior, suggestions for cyberbullying intervention and prevention strategies are formulated.

Kicking someone in cyberspace when they are down: Testing the role of stressor evoked emotions on exposure to workplace cyberbullying

Ivana Vranjes; Elfi Baillien; Heidi Vandebosch; Sara Erreygers; Hans De Witte

ABSTRACT New technologies at work broaden the scope of bullying behaviours to the online context, creating opportunities for a new form of bullying to arise – workplace cyberbullying. So far, knowledge on the factors contributing to workplace cyberbullying has been lacking. Within this emerging research line, the Emotion Reaction model, specifically focused on workplace cyberbullying, was put forward. In this study, we test the model’s main proposition regarding exposure to workplace cyberbullying; namely, that stressors evoked emotions predict exposure to cyberbullying and that this relation is moderated by emotion regulation strategies. The model was tested in two steps. First, the model as a whole was tested cross-sectionally. Next, the direction of causality between fear and sadness and exposure to cyberbullying was tested using a cross-lagged panel design. The results provide support for the central role of fear and sadness in the relationship between work stressors and cyberbullying exposure and the moderating role of reappraisal. No moderating effect of suppression was observed. In addition, support is found for the causal claim that fear and sadness predict cyberbullying exposure. The results and their implications are discussed.

The interplay of negative experiences, emotions and affective styles in adolescents' cybervictimization: A moderated mediation analysis

Sara Erreygers; Heidi Vandebosch; Ivana Vranjes; Elfi Baillien; Hans De Witte

Abstract Cyberbullying research has uncovered several contextual and personal risk factors for cybervictimization, but their interaction has not received much attention. However, the combined influence of several individual and situational factors and the interplay between them may have a different influence on the risk of cybervictimization than each factor separately. Therefore, this longitudinal moderated mediation study, conducted among a large sample of early adolescents, examined how the events adolescents experience in daily life influence their risk of being victimized online via the emotions they experience, and whether this process is moderated by differences in adolescents habitual tendencies to regulate their emotions (affective styles). The results indicated that negative events were directly and indirectly, via experiencing negative emotions, related to later cybervictimization. Furthermore, the association between negative events and emotions was moderated by concealing and tolerating affective styles: Adolescents who habitually concealed or tolerated their emotions were more likely to experience negative emotions associated with negative events, especially when they experienced few negative events. These findings illustrate the importance of taking person-environment-interactions into account when studying cyberbullying and support the implementation of prevention and intervention programs that assist students in developing adaptive emotion regulation and coping skills.
