This thesis conducted three studies to explore negative emotions associated with dietary self-care and the role of rational and irrational beliefs in people with type 2 diabetes, from the Rational Emotive Behaviour Therapy perspective. The first study employed the Interpretative Phenomenological Analysis approach to explore people's experiences of maintaining good dietary self-care and the role of negative emotions. Guilt, anger, frustration, and feeling irritated, annoyed and depressed were negative emotions resulting from poor dietary self-care and resulting in poor dietary self-care. In study two which employed quantitative methodology, beliefs related to negative emotions were used to develop and validate a diabetes-related food beliefs questionnaire. Rational and irrational food beliefs were held concurrently and associated with distress about dietary restrictions. Irrational food beliefs were also linked to people's dietary self-care activities and dietary self-efficacy. The third study used the experimental method to further test the behavioural and physiological effects of beliefs, using three categories of food pictures. Although rational beliefs were associated with positive emotions, beliefs did not affect electrocortical processing of food pictures. Guilt was associated with high calorie foods and a further distinction was made between the high calorie foods, with larger amplitudes recorded for high-fat savoury foods.
