This thesis considers the traits perfectionism, persistence and perseveration. It consists of a systematic review, an empirical study and a critical appraisal of the process. The systematic review followed on from a previous review by Forsberg and Lock (2006) and examined research on the relationship between perfectionism and eating disorders in athletes. A number of databases were systematically searched for studies conducted between January 2006 and October 2012, which revealed 17 relevant articles. Results showed that it is unclear whether eating disorders and perfectionism are different in athletes as compared with people with eating disorders or control groups (e.g. students). There do seem to be links between eating disorders and perfectionism in athletes, although the relationship is complex. The review concludes with a discussion of limitations and recommendations for future research designs. The empirical study tested the validity, reliability and factor structure of the Persistence, Perseveration and Perfectionism Questionnaire (PPPQ-22), as well as links with general psychopathology and eating pathology. One hundred and eighty adult participants, including 23 with current eating disorders, took part online. They completed the PPPQ-22 in addition to existing measures of persistence, perseveration and perfectionism, as well as measures of eating and general psychopathology. The PPPQ-22 subscales were reliable and showed higher correlations with theoretically similar measures. However, the hypothesised three factor structure of the PPPQ-22 was not fully supported. Higher levels of perseveration predicted greater levels of general and eating psychopathology. Study limitations and the implications for psychological theory and treatment are discussed. The critical appraisal considers the use of online testing in more depth, including advantages and limitations, ethical implications and technical aspects.
