This study aimed to describe the course of early onset eating disorders in a population-based sample followed from 14 to 20 years; identify variables that could account for the persistence of eating disorders from 14 to 20 years; and describe outcome of early onset eating disorders with reference to general and psychological functioning at age 20. Participants (N?=?1,383; 49 % male) were drawn from the Western Australian Pregnancy Cohort (Raine) Study, which has followed children from pre-birth to young adulthood. Eating disorder symptoms were assessed using an adapted version of the Eating Disorder Examination-Questionnaire, at ages 14, 17 and 20. At age 14, 70 participants met DSM-IV criteria for a binge eating or purging eating disorder. Nearly half (44 %) of these adolescents ceased to meet criteria for an eating disorders at ages 17 and 20, whilst one-quarter still met criteria for an eating disorder at age 20 and one-fifth met criteria for an eating disorder at all three time points. Purging at age 17 and externalising behaviour problems at age 14 were the strongest predictors of eating disorder persistence to age 20. Participants who experienced a persistent eating disorder were less likely to complete high school than other participants, and reported pronounced depressive and anxiety symptoms at age 20. This study provides new data the course and outcome of early onset eating disorders at a population level. Behavioural difficulties in early adolescence and purging in middle adolescence may predict persistent eating pathology to young adulthood. 相似文献

Two studies are reported which test the hypothesis that extraverts are more tolerant of cognitive inconsistency than are introverts. The first study tested this prediction in the context of Heider's balance model. While degree of extraversion did not moderate reactions to imbalance, extraverts did show less aversion to interpersonal disagreement than introverts. When coupled with other recently published data this suggests that extraverts find arousing social situations less aversive than introverts. In support of the main hypothesis, the second experiment showed that extraverts changed their attitudes less than introverts as a result of writing an essay which was counter to their own attitude under conditions where they had high perceived freedom of choice. 相似文献

Retrieval-induced forgetting refers to a paradoxical occurrence wherein the act of remembering some material disrupts the retrieval of other, related material (see, e.g., M. C. Anderson, R. A. Bjork, & E. L. Bjork, 1994). This effect is generally accounted for in terms of inhibitory processes. Across three experiments, we test the inhibitory account of retrieval-induced forgetting, as well as whether there may be a strategy disruption component to the effect. In our first two experiments, we manipulate which items individuals are cued to recall during retrieval practice and demonstrate that retrieval-induced forgetting can be neutralized when those items do not interfere with the individual's retrieval strategy. In the third experiment, we confirm this finding with a different set of stimuli. These results are inconsistent with a purely inhibitory account of retrieval-induced forgetting, and we discuss implications for inhibition theory and strategy disruption in light of these and other findings. 相似文献
