Starting from the critical review of various motivational frameworks of change that have been applied to the study of eating disorders, the present paper provides an alternative conceptualization of the change in psychotherapy presenting a single-case study. We analyzed six psychotherapeutic conversations with a bulimic patient and found out narratives “for” and “against” change. We read them in terms of tension between dominance and exchange in I-positions, as described by Hermans. These results indicate that the dialogical analysis of clinical discourse may be a useful method to investigate change from the beginning to the end of therapy.

Why no cognitive body image feature such as overvaluation of shape/weight in the binge eating disorder diagnosis?

OBJECTIVE: Undue influence of body shape or weight on self-evaluation-referred to as overvaluation-is considered a core feature across eating disorders, but is not a diagnostic requirement for binge eating disorder (BED). This article addresses the relevance of a feature reflecting disturbance in body image for the diagnosis of BED. METHOD: The distinction between overvaluation of shape/weight and body dissatisfaction is discussed, and empirical research regarding the concurrent and predictive significance of overvaluation of shape/weight for BED is reviewed. RESULTS: The literature suggests that overvaluation does not simply reflect concern or distress commensurate with excess weight, is reliably associated with greater severity of eating-related psychopathology and psychological distress, and has reliably shown negative prognostic significance. DISCUSSION: Overvaluation of shape/weight warrants consideration as a diagnostic specifier for BED. © 2012 by Wiley Periodicals, Inc. (Int J Eat Disord 2012).

INTRODUCTION. Recent studies have shown that alterations to the executive cognitive functions may be endophenotypes of eating disorders. AIM. To perform a critical review of the literature on neuropsychological alterations in patients with eating disorders and their first-degree relatives. DEVELOPMENT. We review the papers written in English and in Spanish indexed in Medline and PsycINFO over the last 10 years. We included abstracts of papers that have still not been published and search terms were crossed. Excluding some isolated clinical cases, we obtained 41 studies on patients with anorexia nervosa (n = 17), bulimia nervosa (n = 5), both (n = 13) or a non-specific eating disorder (n = 6). CONCLUSIONS. The studies reviewed display important limitations due to their heterogeneous methodology and small samples, which give rise to contradictory results. Most of them were conducted on anorexia nervosa. Cognitive rigidity seems to be more frequent in patients with anorexia and their relatives, and alterations in decision-making or central coherence is more often found in bulimia nervosa. There is evidence suggesting that the neuropsychological alterations found in eating disorders are endophenotypes of the disease.

OBJECT: Ultra-high field (UHF) neuroimaging is usually conducted with volume transmit (Tx) and phased array receive (Rx) coils, both tightly enclosing the object. The travelling-wave (TW) concept allows a remote excitation offering more flexible experimental setups. To investigate the feasibility of primate MRI in horizontal UHF MRI, we first compared the distribution of the electromagnetic fields in an oil phantom and then verified the concept with an in vivo experiment. MATERIALS AND METHODS: In the phantom experiments an in-house circularly polarized hybrid birdcage coil and a self-developed patch antenna were used for Tx and an eight-element phased array antenna for Rx. B (1) (+) fields were calculated and measured for both approaches. For in vivo experiments the Rx part was replaced with an optimized three-element phased array head coil. The SAR was calculated using field simulation. RESULTS: In the phantom the field distribution was homogenous in a central volume of interest of about 10 cm diameter. The TW concept showed a slightly better homogeneity. Examination of a female crab-eating macaque led to homogeneous high-contrast images with a good delineation of anatomical details. CONCLUSION: The TW concept opens up a new approach for MRI of medium-sized animals in horizontal UHF scanners.
