v support and supplications. Taufik, Rachid, Jamal, Farouk, Riaz and Faisal have been my goto-men. Words cannot express my gratitude to my sister, Noor Aini. She has been the bedrock in my life. When our father passed away, she has assumed the role entirely and sacrificed herself for the family's benefit. I would not have been able to achieve the things I did without her. Thanks to my younger brother for his in-depth discussions in life and being a good friend. I dedicate my work to my four lovely children-Haney, Hud, Zainal Abidin and A'isyah, and my nephew, Muhammad, whom I consider as my own. I appreciate my wife; Wan Azrina does not seem to be fazed by the hassle of managing our four young children. She took over the dual role of being a mother and a father, especially towards the end of my thesis writing. Most of my friends tell me that I am lucky to have a "cool" mother. When I was in primary school, the vice-principal of Tao Nan School commended my mother because she would cook for my friends and took care of them before we go for our co-curricular activities. She continued this tradition until I was in college. My house was known as the "port" among my friends where they would come to chill-out. My mother has been supportive of everything I do and provides me with advice whenever I need one. I know in seclusion, she would supplicate and seek blessings for me. I know my late father has been doing the same. vi SUMMARY Diabetes is a major cause of death worldwide and ranks amongst killer diseases such as cancer and cardiovascular diseases. The Malays with Type 2 diabetes were being investigated in this research as they are the most susceptible to the disease compared to the other ethnic groups in Singapore. Among the non-clinical intervention programmes, scholarly articles suggest that emotion-based health messages can be a powerful driver to promote health preservation attitudes and behaviours. The objective of this research was to investigate the influence of fear-based messages on patients' behaviours in managing their diabetes condition. To achieve this objective, the research was divided into three phases. In Phase I, forty stimuli were curated. Eight patients with diabetes and eight healthcare providers took part in two separate focus group discussions (FGDs) and a one-to-one interview to determine the appropriateness of the stimuli curated. In Phase II, 100 patients were recruited and asked to rank the stimuli according to three emotion metrics: valence, arousal and dominance. The metrics were derived from the standard Self-Assessment-Manikin (SAM). In Phase III, the rated stimuli were used in a 2 (high-threat, low-threat) x 2 (image, text) factorial design experiment, where 60 patients were recruited. The research findings indicated that varying the threat levels and manipulating the type of format (image or text) had no significant impact on Malay patients accepting the health messages. However, it was found that varying threat levels could influence message acceptance among Malay patients when mode...
