The Measurement and Impact of Workplace Cyberbullying Samuel Farley Institute of Work Psychology Sheffield University Management School University of Sheffield Thesis submitted for the degree of Doctor of Philosophy September 2015 Acknowledgements I would like to thank my supervisors Carolyn Axtell, Christine Sprigg and Iain Coyne for the constant support they have given me over the past three years. They have answered my daily email bombardments with saint-like patience and have been enormously generous with their encouragement. I must also acknowledge staff within Sheffield University Management School for the time and advice they have given me, and I owe huge thanks to the Management School for funding this Ph.D. The past few years would not have been the same without my office mates Liam Goucher, Rob Marchand and Peter Crellin. The enduring memories from this Ph.D will centre around life in B03, including the coffee breaks, Sainsbury’s trips and most of all the arguments. I am especially grateful to Liam and Debs for letting me stay over so often, even though you were quite rude about my washing-up skills. I would also like to thank my fellow Ph.D. students at the doctoral centre for all the good times. If we ever go to the Lake District again I promise to take you on a regular walk and not a nine hour hike. There are numerous friends and family members who have helped me along this journey. Most importantly I would like to thank my Mum and Dad who have supported me through countless years of university (in return I’ll not to make you read this) and both Robbie and Josh for being around on Sky Sports Super Sundays. Finally, I would like to thank Kim for being a source of empathy and love, and for keeping me going when it was tough.

Abstract This thesis investigates workplace cyberbullying, defined as a situation where over time, an individual is repeatedly subjected to perceived negative acts conducted through technology (for example, phone, email, web sites, social media) which are related to their work context. In this situation the target of workplace cyberbullying has difficulty defending him or herself against these actions. The thesis has two broad aims: (1) to develop a workplace cyberbullying measurement scale; and (2) to investigate the impact of workplace cyberbullying on employees. Workplace cyberbullying is conceptualised in this thesis by drawing on the traditional workplace bullying and cyberbullying literature. A rationale is presented for investigating it as a distinct form of workplace bullying and four separate studies address the development of the workplace cyberbullying measure (WCM). The first study generated measurement items by asking employees to describe cyberbullying behaviours. The behaviours were sorted into categories using content analysis and converted into measurement items. In the second study, the relative severity of each item was assessed so that the measure could be weighted according to severity. In the third study, the 34 item WCM was completed by a sample of 424 employees. A two factor structure (comprising work-related cyberbullying and person-related cyberbullying) was compared to a unidimensional factor structure and the measure was refined into a 17 item instrument. During the fourth study the nomological network of the WCM was constructed and further reliability and validity evidence was obtained. The fifth and final study then used the WCM to investigate the impact of workplace cyberbullying within a theoretical framework. The theoretical and practical contributions of the studies are discussed along with directions for future research.
