ABSTRACT

Research on the epidemiology of bulimia nervosa has focused largely on the prevalence of the disorder. As methods have improved, consensus has increased regarding the prevalence rate among adolescent and young adult women--about 1%. However, the accuracy of this figure and its clinical significance must be questioned. In this synthesis of the epidemiological work to date, the authors review the literature from a clinical and research perspective. They recommend a shift in emphasis away from studies of the distribution of the disorder toward studies of the determinants of the whole spectrum of the disturbance that exists in the community.

    • "Las investigaciones en otros países con adolescentes, y principalmente en zonas industrializadas, señalan que los TCA han tenido en los últimos años un alto crecimiento en las mujeres y se encuentran muy cerca de definirse como epidemia social (Anderson-Fye & Becker, 2004; Beach, 1996; Gordon, 1990 citados en Zeledón, 2004; Rozenzweig & Spruill, 1987). Una gran cantidad de investigaciones han estimado su prevalencia del 1% al 8% de la población femenina (Abraham & Llewellyn-Jones, 1992; APA, 2000; Fairbun & Beglin, 1990; Hoek, 1993; Rand & Kuldau, 1992) y del 4.5% al 13% en estudios de comunidades modelos (Bhugra & Bhui, 2003; Halmi, Falk & Schwartz, 1980; Pyle et al., 1983). Sin embargo, los profesionales de la salud consideran que los números de prevalencia reales deben ser mucho mayores, pues quienes padecen estos trastornos tienden a esconderlos. "

    ABSTRACT: Se analiza la validez discriminante del Eating Attitudes Test (EAT-40) mediante la Teoría de Respuesta al Ítem y su modelo de un parámetro, conocido como modelo de Rasch. El EAT-40 (Garner & Garfinkel, 1979) consiste en un instrumento de detección temprana del riesgo de desarrollar trastornos de la conducta alimentaria (TCA), cuyas evidencias de validez en Costa Rica se repasan en este trabajo. Para este estudio se aplicó la versión española del instrumento (Castro, Toro, Salamero & Guimerá, 1991) a una muestra de 556 mujeres del área metropolitana de Costa Rica, con un edad promedio de 17.66 años (DE = 6.65). Para aumentar la variabilidad de las puntuaciones, la muestra estuvo compuesta por estudiantes de colegio (n = 391, 70.3%), de universidad (n = 120, 21.6%), de academias de ballet (n = 26, 4.7%) y pacientes hospitalizadas por bulimia nerviosa o anorexia nerviosa (n = 19, 3.4%). Mediante el modelo de Rasch, el análisis del mapeo de dificultad, y el análisis de las curvas características de los ítems y de la prueba completa, se obtuvo evidencia consistente de la capacidad de los ítems del EAT-40 para discriminar entre personas con y sin riesgo de TCA. En el apartado final se discuten los hallazgos y se abordan las limitaciones del tamaño de la muestra clínica.

    ABSTRACT: Objective: The Eating Disorder Inventory (EDI) is used worldwide in research and treatment of eating disorders (EDs). Using the latest version (EDI-3: 91 items), we extracted the best screening items for a diagnosis of anorexia (AN) and bulimia (BN) nervosa. Method: A patient sample of 561 women was recruited from an ED treatment centre in Denmark, and a comparison group of 878 women was randomly selected from the general population. An ED diagnosis was determined according to the Eating Disorder Examination Interview, yielding 84 AN and 202 BN patients. Results: Only two EDI items (Cronbach's α = .79) were needed to achieve a superior screening capability of BN (sensitivity = .94, specificity = .94). An adequate screening of AN was possible by using three items (α = .71; sensitivity = .91, specificity = .86). Discussion: The present study provides an even more economical and reliable screening of AN and BN compared with existing screening instruments. Implications for DSM-5 are also discussed.

    • "As a result of this recognition, there now exist several two-stage studies in which self-report questionnaires were followed by interviews to confirm or disconfn'm the diagnosis (Button & Whitehouse, 1981; Clarke & Palmer, 1983; Meadows et al., 1986; Nagelberg, Hale, & Ware, 1984; Nevo, 1985; Shefer, 1987; Whitehouse, Phil, & Button , 1988). However, as pointed out by Fairburn et al. (1990), a problem is that these studies simply include a statement noting that individuals misdiagnosed by selfreport were eliminated from the study; there are only about nine studies that have included a report of the actual percentage of individuals misdiagnosed by the self-report inventory (e.g., false-positive rates) or the level of agreement (e.g., kappa) between self-report and clinical interview diagnoses (de Zwaan et al., 1993; Freeman & Henderson, 1988; Johnsone-Sabine et al., 1988; King, 1986; Pyle et al., 1986; Schotte & Stunkard, 1987; Spitzer et al., 1993; Szmukler, 1982; Williams, Schaefer, Shisslak, Gronwaldt, & Comerci, 1986). Of these nine studies, only four have been concerned with the evaluation of questionnaires that operationalize DSM criteria (de Zwaan et al., 1993; Pyle et al., 1986; Schotte & Stunkard, 1987; Spitzer et al., 1993).
