The thesis presented includes a systematic literature review, an empirical paper, and a critical appraisal containing wider reflections on the thesis.
Chapter One outlines a systematic literature review exploring the efficacy of psychological interventions for individuals living with Binge Eating Disorder (BED) and comorbid Obesity. A systematic search identified 17 quantitative studies, which were in line with PRISMA guidelines and analysed using narrative synthesis. Results showed psychological interventions are effective in reducing binge eating, and for some a reduction in weight and improvements in psychological wellbeing. However, most studies focused on a Cognitive-Behavioural Therapy approach and recorded outcomes and delivery of interventions varied. The findings are discussed in relation to research surrounding BED and individuals living with obesity. Further research exploring different therapeutic interventions, particularly in the UK, is required before conclusions can be drawn from the findings.
Chapter Two explores the empirical paper which aimed to gain an in-depth understanding of psychologists’ views of psychological support provision in Specialist Weight Management Services (SWMS). Ten UK psychologists working within SWMS voluntary participated in individual semi-structured interviews conducted online; with transcripts analysed by reflexive thematic analysis. Three themes were identified: (1) The ethical impact and moral injury for staff; (2) The domino effect of demand outweighing resource; and (3) Misunderstanding the complexity of SWMS and the role of psychology within this. Each theme had multiple subthemes. The research found perceived gaps within SWMS, alongside suggestions for future research. Clinical implications from the findings of this research are discussed, particularly in relation to commissioners and staff within SWMS, with the aim of better supporting patients in the future.
Chapter Three includes a critical appraisal summarising research findings, including strengths and limitations, research implications, and suggestions for future research. The author’s personal reflections and decision making are further explored.
