Multifactorial assessment of bulimia nervosa.

Abstract

We investigated a multifactorial approach to the assessment of bulimia nervosa by means of hierarchical factor analysis. Two hundred forty-five bulimia nervosa patients and 68 patients with either anorexia nervosa or eating disorders not otherwise specified were administered a self-report battery that was organized into 21 dimensions relevant to eating disorder patients. When dimensions from this battery were subjected to hierarchical factor analysis, support for bulimia nervosa as a unique diagnostic category was obtained. However, the emergence of 3 secondary factors and 6 primary factors suggests that bulimia nervosa can also be described more complexly. The emergence of a multifactorial model of bulimia nervosa that incorporates several existing undimensional models suggests the potential for both divergent and complicated clinical presentation in bulimia nervosa patients.

Personality disorders in patients with eating disorders in Japan

“…These findings indicate that the severity of binge-purge behavior may not represent the global impulsivity being characterized as the borderline pathology and that impulsive behaviors such as alcohol and drug abuse, self-mutilation, or suicidal attempts are related to a generalized impulsivity and a self-regulatory difficulty of the borderline pathology. Some research on the structure of BN suggested that there exists an intriguing degree of independence between eating symptoms and the severity of comorbid character disturbance (Tobin, Johnson, Steinberg, Staats, & Dennis, 1991;Gleaves, Williamson, & Barker, 1993). Additionally, Steiger et al (1993Steiger et al ( , 1996 and Steiger, Thibaudeau, et al (1994) suggested that character disturbance is more strongly linked to the course of general psychiatric symptoms such as depression, borderline symptoms, and reliance on maladaptive defenses than it is to the course of eating disturbances.…”

Wie lassen sich bulimische Symptome erfassen? Ein psychometrischer Vergleich von Fragebogenskalen

“…Die Restraint Scale (RS) [Laessle et al, 1989] erhebt (8) Gewichtsfluktuationen und (9) Diätsorgen. Der Fragebogen zum Essverhalten (FEV) [Pudel und Westenhöfer, 1989] [Tobin et al, 1991;Gleaves et al, 1993;Gleaves und Eberenz, 1995;Varnado et al, 1995] gestützt. Auch die uneindeutige Zuordnung der Skala Schlankheitsdrang zeichnete sich bereits ab Killen et al, 1994].…”

“…In ihr deutet sich auch an, wie stark das Ergebnis einer Faktorenanalyse von den a priori berücksichtigten Variablen abhängen kann, denn die Extraktion eines Faktors «Gezügeltes Essverhalten/Gewichtsfluktuationen» ohne die BMI-Variablen erscheint wenig wahrscheinlich. Zumindest Hinweise auf die Konstruktvalidität von Skalen zur Erfassung von Ernährungsverhalten und Figurbewertung finden sich auch in Studien, die sich mit der Dimensionalität von Symptomen der Bulimia nervosa beschäftigen [Tobin et al, 1991;Gleaves et al, 1993;Gleaves und Eberenz, 1995;Varnado et al, 1995]. Auch für diese Untersuchungen gilt, dass sie sich nicht primär auf die Analyse von Fragebogenskalen beschränken, sondern zusätzlich Aspekte wie die Anzahl der wöchentlichen Essanfälle [Gleaves und Eberenz, 1995], das Körpergewicht [Tobin et al, 1991] oder Körperbildein-schätzungen [Varnado et al, 1995] [Margraf et al, 1994] anhand der DSM-III-R Kriterien vergeben.…”

The social self in bulimia nervosa: Public self-consciousness, social anxiety, and perceived fraudulence.

“…Eating disordered patients appear preoccupied with self-presentation and with how others perceive and evaluate them, a facet of the self first designated the "social self" by William James (1890. ' Research suggests that women with bulimia nervosa and anorexia nervosa experience significant difficulties in the area of social adjustment, characterized by social anxiety, impoverished relationships, and social isolation (Fairburn et al, 1990;Grissett & Norvell, 1992;Herzog, Pepose, Norman, & Rigotti, 1985;Johnson & Berndt, 1983;Mizes, 1988;Norman & Herzog, 1984;Rybicki, Lepkowsky, & Arndt, 1989;Tobin, Johnson, Steinberg, Staats, & Enright, 1991;Yager, Landsverk, & Edelstein, 1987). The social disturbances do not seem to relate simply to eating pathology: Even after the behavioral symptoms of eating disorders remit, social maladjustment has been found to persist for many patients (Casper, 1990;Herzog, Keller, Lavori, Bradburn, & Ott, 1990;Mallik, Whipple, & Huerta, 1987;Norman, Herzog, & Chauncey, 1986;Stonehill & Crisp, 1977;Yager et al, 1987).…”
