Is overestimation of body size associated with neuropsychological weaknesses in anorexia nervosa?

Background: Recent research indicates some evidence of neuropsychological weaknesses in visuospatial memory, central coherence and set-shifting in adults with anorexia nervosa (AN). The growing interest in neuropsychological functioning of patients with AN is based upon the assumption that neuropsychological weaknesses contribute to the clinical features of the illness. However, due to a paucity of research on the connection between neuropsychological difficulties and the clinical features of AN, this link remains hypothetical.

Are poor set-shifting abilities associated with a higher frequency of body checking in anorexia nervosa?

Background: The rigid and obsessional features of anorexia nervosa (AN) have led researchers to explore possible underlying neuropsychological difficulties. Numerous studies have demonstrated poorer set-shifting in patients with AN. However, due to a paucity of research on the connection between neuropsychological difficulties and the clinical features of AN, the link remains hypothetical.

Validation of the Norwegian short version of the Body Shape Questionnaire (BSQ-14).

Background: The Body Shape Questionnaire (BSQ) is a widely used self-report measure of body shape dissatisfaction.

Aims: We aimed to establish psychometric properties and report normative data for the Norwegian 14-item BSQ in a clinical and non-clinical sample.

Methods: A total of 423 female students, 267 male students and 49 female inpatients [anorexia nervosa (AN) and subthreshold AN] were administered the BSQ, the Body Checking Questionnaire (BCQ), and the Eating Disorder Examination Questionnaire (EDE-Q).

Memory versus perception of body size in patients with anorexia nervosa and healthy controls.

The objective of this study was to compare body size estimation based on memory versus perception, in patients with anorexia nervosa (AN) and healthy controls, adjusting for possible confounders. Seventy-one women (AN: 37, controls: 35), aged 14-29 years, were assessed with a computerized body size estimation morphing program. Information was gathered on depression, anxiety, time since last meal, weight and height.

Nibbling: frequency and relationship to BMI, pattern of eating, and shape, weight, and eating concerns among university women.

Objective: Nibbling has been defined by the Eating Disorder Examination (EDE 16.0) as eating in an unplanned and repetitious manner between meals and snacks without an accompanying sense of loss of control. We investigated the nature and frequency of nibbling in young women.

Convergent validity of the eating disorder examination and the eating disorder examination-questionnaire among university women in Norway.

The present study compared the Eating Disorder Examination (EDE; 16.0) and the Eating Disorder Examination-Questionnaire (EDE-Q; 6.0) and investigated the psychometric properties of the Norwegian translation of the EDE.

Psychometric properties of the clinical impairment assessment: norms for young adult women.

Objective: This study aimed to investigate the initial psychometric properties and to establish norms for the Clinical Impairment Assessment (CIA v. 3.0) among a nonclinical sample of young adult women.
