DRIVING ANGER: THE ROLE OF PERSONALITY ATTRIBUTES, EMOTIONAL INTELLIGENCE, GENDER AND AGE Melissa Esterhuyse Thesis submitted in partial fulfilment of the requirements for the degree of Master of Commerce (Industrial Psychology) in the Faculty of Economic and Management Sciences at Stellenbosch University Supervisor: Dr Billy Boonzaier March 2017 Stellenbosch University https://scholar.sun.ac.za i DECLARATION By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification.

Furthermore, the same study shows that only between 3% and 5% of traffic accidents could be blamed on the environment in which the individual is travelling, and another small percentage of accidents can be attributed to flaws of the vehicle. Driving anger can be defined as the propensity to become angry while driving, an individual characteristic unique to every driver (Deffenbacher, Deffenbacher, Lynch & Richards, 2003). Research shows that high driving anger is related to risky driving behaviours, such as fast driving, reckless manoeuvers and violations of traffic laws (Sarbescu, Costea & Rusu, 2012; Villieux & Delhomme, 2010). The study of driving anger includes the way an individual experiences or deals with anger. Hence, driving anger is assumed to form part of internal factors (driver characteristics) impacting a larger, more complex system. This complex system consists of external and internal factors working together that consequently influence each other and traffic safety (i.e. traffic outcomes and consequences). The main objective of this study was to develop a structural model, based on the current literature, which explains the antecedents of driving anger, and to empirically test this structural model. The antecedents comprise personality attributes (agreeableness, conscientiousness, neuroticism, openness to experience and extraversion), emotional intelligence, gender and age, and the impact that these factors have on driving anger. An ex post facto correlational design was used to test the hypotheses formulated specifically for the purpose of the current research study. Convenience sampling (as well as elements of stratified random sampling) was used to select a sample. Quantitative data was collected from a total of 199 drivers; 50 professional and 149 non-professional drivers. An online electronic survey was distributed to Pepkor and Lube Marketing employees, amongst others using social media and networking strategies. The following measurement instruments were used: (1) the International Personality Item Pool (IPIP) (Dahlen & White, 2006), (2) the Schutte Emotional Intelligence Scale (SEIS) (Davies, Lane, Devonport & Scott, 2010), and (3) the Driving Anger Scale (DAS) (Deffenbacher, Oetting & Lynch, 1994). Gender and age were measured via biographical questions asked in the survey. Item analysis, partial least squares (PLS) and Stellenbosch University https://scholar.sun.ac.za iii multiple regression analysis were conducted to analyse the data that was collected and also to report on the nature of the paths. From the 18 hypotheses formulated in the study, one was found to be statistically significant, namely, the relationship between neuroticism and driving anger. This implies that those high in neuroticism are most likely to experience driving anger. It is important to note that, of the statistically insignificant paths, 12 were related to moderating effects. These statistically insignificant results could be due to many reasons and is discussed in the study. The study has shed some light on the understanding of driving anger and its antecedents as related to professional and non-professional drivers. Based on the results reported, possible interventions for industrial psychologists and managers were suggested to foster a safe driving culture. Furthermore, the limitations of the study and recommendations for future research were discussed.

Thank you for reassuring me that: “nothing will be impossible with God” (Luke 1:37). To Billy and Michele Boonzaier I want to thank you for your guidance and encouragement. As mentors you challenged me to grow in so many different ways. I always felt welcome to reflect with you – thank you. I would like to extend my appreciation to Prof Martin Kidd – thank you for your time and patience in the data collection and analysis process. I value your support. To Pat, my leader at Pep, thank you for allowing me the time to work on this study, and to the Talent Management Team – thank you for your support. It is greatly appreciated. I would also like to thank all of the participants for taking time out to assist me with the study. Thank you to Pep, Pepkor Logistics and Lube Marketing for cooperating in the data collection. Next, to my parents Debbie and Stephan – I cannot express my gratitude. Mom and Dad, words cannot thank you enough for the motivation, love and financial support you gave over the years. It is thanks to you that my dreams of studying became a reality. Dad, you never once doubted my abilities and always helped me see the positive side of all the challenges I was faced with. Mom, you always believed in me and picked me up when I felt demotivated. I therefore dedicate this research project to you, the most wonderful parents I could ask for. Thank you for affording me the opportunity to do you proud. To my sister, Reshé, friends and family – your words of encouragement, understanding and love have been a source of strength and motivation. Thank you for showing interest in something so close to my heart. You all have helped me along this amazing journey. Last, but not least, to my fiancé, Westley: You have been my rock. You never once let me think that my challenges could overcome me. You have been an inspiration to me and I could never thank you enough for the love and support you have given me.
