An attempt to understand the paradox of anorexia nervosa without drive for thinness

The "atypical" subgroup of women with anorexia nervosa not characterized by drive for thinness (DT) was studied. The study group comprised 151 anorectic patients (restrictor anorectics [AN-R], n=74; binge-purging anorectics [AN-BP], n=77). Subjects completed the following self-administered questionnaires: Eating Disorder Inventory-2 (EDI-2), Temperament and Character Inventory (TCI), State-Trait Anger Expression Inventory (STAXI), and Beek Depression Inventory (BDI). Patients were subdivided into three groups on the basis of body mass index (BMI) and DT score: AN-I with a BMI < 15 and DT < 7 (n = 24); AN-II with a BMI > 15 and DT < 7 (n=34); and AN-III with a BMI < 17.5 and DT > 7 (n=93). Patients belonging to the AN-III group had a more severe disorder and form of psychopathology based on their scores on several scales. No association emerged between personality disorders and any single subgroup. Three hypotheses emerge: (1) some patients (about 38%) deny DT and provide negative answers on the questionnaires; (2) patients without DT (even when malnourished) seem to show less severe psychopathologic and personality traits; and (3) patients without DT answer questions honestly, but they have developed a character structure that enables them to feel negative and ego-dystonic emotions regarding their condition. Implications for treatment are discussed. (c) 2006 Elsevier Ireland Ltd. All fights reserved.
