Abstract

This thesis examines predictors of self-disgust among a sample who screened positive for personality disorders. It is a joint thesis with ‘The role of self-disgust in non-suicidal self-injury among individuals with personality disorder’ (Schwaiger, 2016). Part 1, the literature review, examines whether self-disgust is associated with psychopathology (as evidenced by a DSM-5 mental health disorder). Seventeen studies indicate that self-disgust is associated with a wide range of mental health disorders including Depression, Borderline Personality Disorder and Eating Disorders. The evidence is limited by the use of largely non-clinical samples, cross- sectional designs, and by theoretical and methodological limitations regarding the operationalisation and measurement of the self-disgust construct. Part 2, the empirical paper investigates predictors of self-disgust using a cross- sectional web-based survey. Self-disgust was elevated in those classified as PD according to a brief screening tool (n =188), relative to a non-PD sample (n=133). Childhood abuse and trauma and shame independently predicted self-disgust in those who screened positive for a probable PD. Self-disgust also mediated the relationship between childhood abuse and trauma and the likelihood of PD. Part 3, the critical appraisal considers outstanding issues regarding the psychometric measurement of self-disgust. Directions for further research are discussed, as are the strengths and limitations of utilising web-based research and social media to aid recruitment in psychological research. Personal reflections are finally offered on how the research has impacted me as a researcher and clinician.
