Section one reports on a quantitative systematic literature review examining the relationship between post-traumatic stress disorder and eating disorders within a military population. Six academic databases were systematically searched using key words related to the concepts of post-traumatic stress disorder, eating disorders, and military personnel and veterans. The findings suggested that there is a significant positive association between post-traumatic stress disorder and eating disorders within a military population. Females were at a greater likelihood than males of experiencing co-occurring post-traumatic stress disorder and eating disorders. Furthermore, longitudinal studies suggested a directional relationship wherein military personnel and veterans experiencing post-traumatic stress disorder were later more likely to engage in disordered eating behaviours. However, the majority of research reviewed was cross-sectional and related to US military veterans, therefore the area would benefit from additional studies, particularly those examining international active military service members and veterans. Section two reports on an empirical study examining the effect of fear of compassion on the relationship between self-criticism and disordered eating within an adult population. Individuals across the spectrum of disordered eating took part in an online survey. A series of mediation models were employed in order to explore the relationships between self-criticism, fear of compassion, and disordered eating. Findings indicated that the relationships between two forms of self-criticism, namely self-critical rumination and self-criticism in relation to a sense of personal inadequacy, and disordered eating were mediated by fear of both showing compassion to oneself and receiving compassion from others. These results highlight a need for the assessment of fear of compassion within therapeutic interventions for people who experience disordered eating, particularly in clients who experience high levels of self-criticism. Section three includes a critical appraisal of the thesis. It includes a summary of overall findings in addition to reflections upon key decision-making points.
