Acknowledgments I would like to thank my supervisor – Professor Allan Luke – for his sustained mentorship and professional insight throughout the research process. I would also like to put on record my thanks to Starhub Pte Ltd for the generous and complimentary provision of the telephone accounts. In addition, I owe a debt of gratitude to the staff and students of Yishun Town Secondary School, Fuchun Secondary School, Bowen Secondary School and Christ Church Secondary School, for agreeing to let me work with them in the field-based interventions. Acknowledgment also goes to the many other people, such as those listed below, without whom this research would not have been possible. To God be the glory for His gracious sustenance and guidance throughout this journey. Research Assistants Travis Teo Jason Wang
