This is an integration of three studies on type 2 diabetes. In this study, diabetes was seen in relation to illness perception, stress, depression, social support, and self management. The studies conducted using quantitative approach, employing 68 participants, aged between 40–75 years old. Interviewer-administered questionnaires were used for the data collection. Sobel test was employed to examine the mediation states of the variables in the three quantitative studies, and regression analysis was then executed for hypotheses testing. Results show that self-acceptance were significantly related to depression (r:-.14, p .05). Religiosity approved to be significantly related to the stress (r:-.69, p<.05), mediated by self acceptance (r:-.36, p<.05). “Easily being tired in work, compared to the previous condition” was identified by most of the study participants as the cause of stress. It was also discovered that illness perception and coping strategies were not having a direct association with self-management in general. This study suspected that there was multicollinearity among 8 sub-components of illness perception, coping strategies and self-management. Conclusion: self-acceptance is the most important among others; and that participants, with family, need to have correct knowledge on the nature of the illness and its management.
