Anorexia nervosa is recognised as a complex and chronic disorder that is often associated with poor prognosis and severe psychological and physiological consequences. Previous research has identified an array of factors associated with anorexia nervosa of which self-esteem, self-concept and body image are amongst the most commonly cited factors involved in the development and maintenance of the disorder. Capitalising on recent advances that have been made in other realms of psychology, the current study attempts to address current limitations regarding self-esteem, self-concept, body image and experiences of adolescent girls with anorexia nervosa. More specifically, a series of three studies were designed to address : a/ self-esteem and self-concept ; b/ body image and the association between body image and self-concept; and c/ the experiences and support needs of young people with eating disorders.The current findings have demonstrated that whilst quantitative methods can be effectively utilised to elucidate various relations between predictor and outcome variables, qualitative methods can offer important insight into the patient with the eating disorder On a more general level, the current results obtained from the current series of studies may be able to inform current conceptualisations of anorexia nervosa and the future development of aetiology and treatment programs. / Doctor of Philosophy (PhD)

The purpose of this study was to quantitatively evaluate the overall effectiveness of eating disorder prevention programs and to investigate potential moderating variables that may influence the magnitude of intervention effects. Meta-analysis was used to conduct a comprehensive and systematic analysis of data across 46 studies. Effect size estimates were grouped into outcome sets based on the following variables: knowledge, general eating pathology, dieting, thin-ideal internalization, body dissatisfaction, negative affect, and self-esteem. Q statistics were used to analyze the distribution of effect size estimates within each outcome set and to explore the systematic influence of moderating variables. Results revealed large effects on the acquisition of knowledge and small net effects on reducing maladaptive eating attitudes and behaviors at posttest and follow-up. These programs were not found to produce significant effects on negative affect, and there were inconsistent effects on self-esteem across studies. Population targeted was the sole moderator that could account for variability in effect size distributions. There was a tendency toward greater benefits for studies targeting participants considered to be at a relatively higher risk for developing an eating disorder. Previous assumptions regarding the insufficiency of "one-shot" interventions and concerns about the iatrogenic effects of including information about eating disorders in an intervention were not supported by the data. These findings challenge negative conclusions drawn in previous review articles regarding the inability of eating disorder prevention programs to demonstrate behavioral improvements. Although these findings have implications for the prevention of eating disorders, it was argued that a clear link between intervention efficacy and a decreased incidence of eating disorders was not demonstrated. Rather, only direct information was offered about the ability to influence eating disorder related knowledge, attitudes, and behaviors. Specific recommendations related to intervention content, reasonable goals/expectations, and outcome criteria were offered for improving research in this area.

The purpose of this study was to investigate the influence of childhood sexual, physical and emotional abuse and childhood emotional and physical neglect on eating disorder symptoms and general psychopathology. This study utilized a cross-sectional research design incorporating a combination of self-report measures and clinical interviews. Seventy participants were recruited from two eating disorder treatment centres. A series of univariate tests revealed no significant differences between individuals who reported a mild level of trauma and those who reported a severe level of trauma on all clinical measures. Logistic regression analyses revealed associations between impulsivity and childhood physical abuse and between psychiatric comorbidity and childhood physical neglect. Few associations were found and the observed effect sizes were generally small suggesting that the null findings were not due to inadequate power. It may be that the study sample differed from those used in previous investigations in which significant associations have been documented.

The purpose of this research was to develop and evaluate a 5-week readiness for change precursor to group cognitive-behavioral therapy for individuals with eating disorders. Group content was based on the theories of the Transtheoretical Model of Change and Motivational Interviewing, and also included an experiential pretraining component. Forty-six medically stable individuals with anorexia nervosa, bulimia nervosa or eating disorder not otherwise specified (EDNOS) were recruited from the Adult Eating Disorders Program at the Health Sciences Centre in Winnipeg, Canada. Participants completed measures of readiness for change, eating disorder symptomatology, and treatment outcome at three time points: pre- and post-readiness precursor, and post-cognitive-behavioral group. One-way repeated measures analysis of variance, regression analysis, and Cochran’s Q analysis were used to investigate hypotheses. Results revealed that participants’ readiness for change increased significantly following the readiness group. However, despite changes in readiness, stage of change awareness and cognitive-behavioral treatment drop-out rates were not significantly improved. In was concluded that motivational interventions appear to be an effective way to increase readiness for change in the eating disorders, however more research is needed to determine whether increases in readiness have a significant impact on treatment outcome.
