Interaction between disinhibition and restraint: Implications for body weight and eating disturbance.Bryant, Eleanor J., Keizebrink, K., King, N., Blundell, J.E. 03 1900 (has links)
yes / An increase in obesity is usually accompanied by an increase in eating disturbances.
Susceptibility to these states may arise from different combinations of underlying
traits: Three Factor Eating Questionnaire (TFEQ) Restraint and Disinhibition. Two
studies were conducted to examine the interaction between these traits; one on-line study
(n=351) and one laboratory-based study (n=120). Participants completed a battery of questionnaires
and provided self-report measures of body weight and physical activity. A combination
of high Disinhibition and high Restraint was associated with a problematic eating
behaviour profile (EAT-26), and a higher rate of smoking and alcohol consumption. A
combination of high Disinhibition and low Restraint was associated with a higher susceptibility
to weight gain and a higher sedentary behaviour. These data show that different
combinations of Disinhibition and Restraint are associated with distinct weight and behaviour
outcomes.

Body Image, Self-Esteem and Eating Disturbance among Chinese Women: Testing the Tripartite Influence modelWang, Weiwei 29 October 2018 (has links)
The purpose of the study is to confirm the reasons behind young Chinese women’s eating disturbances and self-esteem. The researcher uses the Tripartite Influence model to illustrate the relationship between internalization and pressures in the form of peer, family, and media pressure. It further reveals the relationship between internalization and self-esteem and eating disorders. Besides conforming with the mode of young Chinese females, it aims at finding out the reasons behind each relevant relationship. One point of the study is the different impact of media pressure on young Chinese females; the influence of media tends to be much lower in China and the reasons have been discussed in their entirety.

Early onset Anorexia NervosaRose, Cynthia Beulah 06 1900 (has links)
Text in English / Two consecutive referrals of early onset (symptom onset at 11 years) anorexia nervosa (restricting sub-type) to an inpatient eating disorders unit in a psychiatric hospital, will be described. Within both cases, there was a history of sequential mother-daughter dieting prior to the daughter's onset of anorexic symptoms. This pattern will be viewed from the perspective of systemic theory, with reference to the cybernetic processes implicated in the onset and maintenance of symptoms. Structural systemic interpretations, in terms of exchangeable senses of self within the mother-daughter pairs, will also be considered. A brief comment will be made about the symmetry which underlies the choreography of anorexia nervosa when viewed from the perspective of communication theory. The implications for intervention will be addressed. In conclusion, the nature of the intergenerational
transmission of disordered eating behaviours, will be considered with
reference to the nature-nurture debate. / Clinical Psychology / M.A. (Clinical Psychology)

The Effects of Environmental Enrichment on Stress-Induced Eating Disturbances in RatsChu, Jennifer January 2008 (has links)
Eating disorders are serious psychological disorders associated with debilitating lifestyle, multiple health problems and high rates of suicidality and mortality. Despite extensive research, the aetiology of eating disorders still remains unclear. Amongst the identified risk factors for eating disorders, stress has been frequently studied. The purpose of the present study was to explore the possibility that tail-pinch administered to rats could provide an animal model of stress-induced eating disturbances in humans, and whether environmental enrichment might ameliorate the effects of stress. In Experiment 1, we compared eating behaviours of rats that were reared in either enriched or standard environments and later exposed to tail-pinch and allowed to eat when food deprived. The study showed that a single exposure to tail-pinch induced eating disturbances in most of the rats. When rats were not food deprived, but were conditioned to eating when placed in test chamber, tail-pinch suppressed eating in all rats, but significantly more for rats reared under standard than in enriched conditions. Experiment 2 used a between-subjects design in which rats were reared in either a standard or enriched environment, and were either exposed to tail-pinch or not exposed during sessions in which they were not food deprived and allowed to eat. Tail-pinch suppressed the food intake of rats reared in enriched but not standard environments. Although this finding appeared to contradict results of Experiment 1, analysis of body weight revealed that exposure to tail pinch suppressed increases in weight gain across sessions more for rats reared in standard than enriched environments. The suppression of food intake during test sessions for enriched but not standard rats exposed to tail-pinch was attributed to differences in contextual conditioning and discrimination of the test chamber from home cages. Overall, results of the present study suggest that rats reared in enriched environments were more resilient to the effects of tail-pinch as a stressor. Implications of these findings for the understanding of human eating disorders are discussed.
