“…Not surprisingly, bulimics took signifIcantly more time to eat than the controls, regardless of the drug. Patients knew that they were subject to possible observation during eating and that they would not be able to purge following the testmeal; this situation may have increased food-related anxiety and avoidance be havior (Katzman and Wolchik 1984;Johnson et al 1986;Davis et al 1988). The effects of the artifIcial nature of this eating paradigm on our results must be ac knowledged.…”

A wealth of data support a role for serotonin (5-HT) function in the mediation of satiety responses, that are impaired in patients with bulimia nervosa. Testmeal results are presented in which 26 bulimic patients and 17 normal controls were given in randomized, double-blind-fashion, placebo, and the 5-HT agents m-chlorophenylpiperazine (m-CPP, 0.5 mglkg p.o.) and L-tryptophan (L-TRP, 100 mglkg I. V.). Three and one-half hours after drug administration, subjects were allowed to eat and lib from a standardized testmeal of 3,500 calories, after which postprandial vomiting was not allowed. M-CPP, but not L-TRP, significantly decreased meal size in the combined group, the controls, and to a lesser extent, the bulimics (p � .06). Maximum m-CPP Serotonergic manipulations are known to result in marked changes in feeding behaviors, particularly sati ety responses (Blundell 1977(Blundell , 1984(Blundell , 1986Blundell and Latham, 1978, 1982Latham and Blundell 1979;Samanin et al. 1982;Silverstone and Goodall 1986;Garattini et al., 1988Garattini et al., , 1989, which are dysfunctional in bulimic patients (Owen et al. 1985;Chiodo and Latimer 1986;Kissileff et al. 1986). Pharmacologic en hancement of 5-HT neurotransmission in animals and concentrations were inversely correlated to the number of calories consumed in the total group. Following m-CPP, there were significant decreases in carbohydrate, protein, and fat intake in the total group of subjects. There were also trends for decreased carbohydrate and protein intake in the bulimics following m-CPP. There were trends for both m-CPP and L-TRP to reduce fat intake in the controls. Differences in the effects between m-CPP and L-TRP are likely due to differential involvement of 5-HT receptor subtypes at presynaptic and postsynaptic sites. These studies in humans confirm reports in animals that m-CPP decreases food intake, including carbohydrates, protein, and fat in a mixed testmeal.

“…Esto ha llevado a algunos investigadores (van Strien et al, 2007) a excluir a priori este ítem de los análisis posteriores. Asimismo, en muestras que evaluaron a personas con obesidad o bulimia nervosa (Johnson et al, 1986;Johnson et al, 1983;Lowe, 1984;Ruderman, 1983) se observaron variaciones en la estructura factorial asociadas principalmente en los ítems 6 y 7. En el presente trabajo, así como en otro estudio que utilizó la escala en español de la ER (Silva, 2010), los ítems mencionados cargaron adecuadamente en el factor esperado.…”

“…En otro tipo de poblaciones (i.e. sujetos con sobrepeso) se verifican variaciones en esta solución (Johnson, Corrigan, Crusco & Schlundt, 1986;Johnson, Lake & Mahan, 1983;Ruderman, 1983;van Strien et al, 2007). Bajo esta perspectiva, se ha concluido que la ER es un instrumento válido para ser utilizado en personas de peso normal y no así para personas con sobrepeso u obesidad 1 .…”

La escala de restricción revisada (ER) es un instrumento psicométrico para medir restricción alimentaria crónica. Objetivo: Obtener la fiabilidad y estructura factorial de la versión en español de la ER en una muestra de adolescentes. Materiales y método: 838 adolescentes (15,5 años) completaron el instrumento. Se realizó un análisis factorial exploratorio y confirmatorio sobre los puntajes. Resultados: Ambas sub-escalas de la ER muestran una fiabilidad apropiada, aunque el item 9 mostró una homogeneidad corregida pobre (r<.3). Dos factores correlacionados emergieron del análisis factorial, explicando el 55,76% de la varianza. El análisis confirmatorio develó un ajuste moderado de la estructura bifactorial hipotética. Conclusiones: El instrumento muestra una estructura bifactorial y niveles adecuados de fiabilidad en una muestra de adolescentes.

“…In summary, these results indicate the BCDS and MAC are valid and useful instruments for assessing the cognitions of individuals with bulimia nervosa and for evaluating the effectiveness of cognitive-behavioral interventions for bulimia nervosa that target cognitive change as a treatment goal. While this research may be criticized for failing to recruit a "clinical" sample of women with bulimia, it is important to note that participants were selected on the basis of a standardized interview, and the bulimic group's RRS, EDE, and MAC scores were comparable to those found in clinical populations of women with bulimia (Johnson, Corrigan, Crusco, & Schlundt, 1986;Mizes, 1992;Wilson & Smith, 1989). Thus, our participants with bulimia nervosa may be as pathological as women with bulimia who seek treatment.…”
