CONTEXT Efforts to classify eating-disordered individuals based on concurrent personality traits have consistently converged on a typology encompassing "over-regulated", "dysregulated", and "low psychopathology" subgroups. In various populations, evidence has associated personality variations of an "over-regulated/dysregulated" type with differences on(More)
OBJECTIVES To review the main phenomenological variants observed among bulimia spectrum syndromes and the factors believed to act etiologically for them and also to generate an etiologic model that accommodates known heterogeneities within the population suffering bulimic syndromes. METHOD Defining bulimic syndromes broadly, we address threshold and(More)
BACKGROUND There is empirical evidence suggesting that individuals with bulimia nervosa vary considerably in terms of psychiatric co-morbidity and personality functioning. In this study, latent profile analysis was used to attempt to identify clusters of bulimic subjects based on psychiatric co-morbidity and personality. METHOD A total of 178 women with(More)
OBJECTIVE Impulsivity is generally believed to be more characteristic of individuals with bulimic than with restrictive eating disorders (EDs). However, studies have not exhaustively explored the association between EDs and various component dimensions of the impulsivity construct. METHOD We conducted a multidimensional assessment of impulsivity in 84(More)
Studies have linked bulimia nervosa (BN) to alterations in brain serotonin (5-hydroxytryptamine: 5-HT) activity and to heightened propensity for parasuicidality and self-injuriousness. The coincidence of self-destructiveness and 5-HT abnormality in BN is of interest, given documentation (in various populations) of an inverse association between 5-HT(More)
Findings show brain serotonin (5-hydroxytryptamine (5-HT)) activity to be altered in individuals who have had bulimia nervosa (BN), even after substantial remission of symptoms. Such findings could reflect persistent sequelae due to BN, or a vulnerability 'trait' that exists independently of active eating-disorder manifestations. We compared women with(More)
BACKGROUND In bulimic syndromes, binge episodes are thought to be caused by dietary restraint and negative moods. However, as central serotonin (5-hydroxytryptamine: 5-HT) mechanisms regulate appetite and mood, the 5-HT system could be implicated in diet- and mood-based binge antecedents. METHOD We used hand-held computers to obtain repeated "online"(More)
OBJECTIVE A primary objective of the current article is to investigate the relationship between impulsivity and compulsivity in patients with bulimia nervosa (BN). A second goal is to explore the relationship between impulsivity and compulsivity and related psychiatric problems. METHOD Two-hundred four females with BN completed several measures of(More)
This systematic review summarises and critically appraises the literature on structural magnetic resonance imaging in people with a current or past eating disorder. Studies using voxel-based morphometry image analysis were included. Ten studies reported on a total of 236 people with a current or past eating disorder and 257 healthy controls. Sample(More)
OBJECTIVE Naturalistic studies on sufferers of bulimic syndromes suggest that binge episodes are often precipitated by episodes of dietary restraint. However, evidence also implies that binge eating may, in certain psychopathological contexts, have less direct connection with dietary control factors.
