Validation of the Korean version of the Eating Disorder Inventory-2: psychometric properties and cross-cultural comparison.

Purpose: The purpose of the present study was to examine the validity and reliability of the Korean version of the Eating Disorder Inventory-2 (EDI-2) in Korean patients with eating disorders and healthy controls, and to investigate cultural differences of EDI-2 between a Korean group and a North American standardization sample.

Materials And Methods: The Korean version of the EDI-2 was prepared after comprehensive clinical assessment of Korean patients with eating disorders (n=327) as well as female undergraduates (n=176). Results were compared between eating disorder subgroups (anorexia nervosa, bulimia nervosa and eating disorders not otherwise specified) and those of a North American standardization sample and healthy controls.

Decreased P3 amplitudes elicited by negative facial emotion in manic patients: selective deficits in emotional processing.

Manic patients have impairments in recognizing negative emotional stimuli. However, there have been few studies on manic patients' neurophysiological responses to facial emotions. We measured the P3 event-related potentials using facial emotional stimuli to investigate whether the impairment in recognition of negative emotions is greater in maniac patients.
