The Digitization of Healthcare in Developing Countries: Examining Individuals’ Willingness to Disclose Personal Health Information A thesis submitted in fulfilment of the requirements for the Degree of Doctor of Philosophy in Information Systems By Ernest Kwadwo Adu University of Canterbury 2019 DEDICATION This thesis is dedicated to the Blessed Virgin Mary, the Patroness of my studies, and my late father Mike Okrah i ACKNOWLEDGEMENTS I wish to express my profound gratitude to my supervisors, Associate Professor Annette Mills and Senior Lecturer Nelly Todorova, whose guidance, insights and constructive criticisms have been invaluable in successfully completing this thesis. Their motivation, patience and kindness have also been very helpful, especially during the days when the PhD journey was difficult to travel. I cannot forget the sacrifices they made in the latter stages of my studies to ensure this thesis was completed and submitted on time. Prof. Annette Mills, in particular, spent her entire time while on leave to work on the final chapters of the thesis, to which I am very grateful. I thank God for blessing me with such wonderful people as my supervisors. I would also like to thank the University of Canterbury for awarding me the UC Doctoral Scholarship without which it would have been impossible for me to pursue my PhD studies. I must also acknowledge the constant support and assistance provided by the administrative, academic, and technical staff of the Accounting and Information Systems department. You helped create a supportive, friendly, and conducive environment for learning and research, and for that, I am exceedingly grateful. Thank you also to the friends and colleagues with whom I shared this journey. Your friendship, encouragement, and support helped make pleasant my PhD journey. I am also greatly indebted to Dr Musah Adams of the Department of Information Studies, University of Ghana. Dr Adams taught me during my undergraduate studies and upon graduating, I worked as his teaching assistant. He has played a vital role throughout my academic journey by providing me with academic recommendations and offering needed advice and encouragement. Of course, I cannot thank enough my family and friends back home in Ghana for their constant prayers, love and support. They have been a strong pillar of support throughout my life and especially during this period of intensive learning. Finally, and most importantly, I am eternally grateful to God for his blessings and grace which have brought me this far in my academic career. To HIM be all GLORY, HONOUR, and PRAISE. ii TABLE OF CONTENTS DEDICATION .......................................................................................................... i ACKNOWLEDGEMENTS
