Obesity is one of the most serious public health challenges of the 21<sup>st</sup> century, associated with a range of adverse physical, psychological, social and economic consequences. The aetiology of obesity is complex; however, the psychological factors associated with overweight and obesity remain poorly understood. The first paper critically appraises evidence for three of the most developed psychological theories of obesity. Based on these findings, literature from the fields of emotion regulation and attachment are reviewed, and a novel developmental theory of obesity based on an integration of these theoretical constructs is proposed. Recommendations for future research based on a theoretical framework of emotion regulation are made, and implications for clinical practice including a focus on enhancing caregiver sensitivity are highlighted. The second paper explores the applicability of an established cognitive model of Bulimia Nervosa (BN) and binge eating to an overweight and obese sample. Findings support the relevance of cognitive aspects of the model in an overweight and obese sample, and highlight the potential role of early attachment relationships in the formation of cognitions that make an individual vulnerable to overweight and obesity in later life. Theoretical and clinical implications based on the established cognitive model are considered. Limitations include reliance on self-report and the correlational nature of analyses used. Recommendations for future research with larger, more representative samples to address these limitations are made. Overall, this dissertation makes a unique contribution to the psychological understanding of overweight and obesity, which has the potential to enhance treatment outcomes and suggests useful avenues for further research.
