To determine the relationship between Tridimensional Personality Questionnaire (TPQ) scales and bulimia nervosa, TPQ scores of 27 bulimic women, age range 21-59, were compared with values for an age-matched sample of 128 normal control women drawn from the national norming sample by Przybeck. Scores for Novelty Seeking and Harm Avoidance were significantly higher, while scores for Reward Dependence were significantly lower for the bulimic women. A stepwise regression model of severity of purging on TPQ selected Novelty Seeking and a composite depression score, with Novelty Seeking being the stronger of the two predictors. Whole blood serotonin levels did not relate to TPQ scores or to purging frequency.

The nature of visual and auditory coding processes in students with learning disabilities (SLDs) and student controls (SCs) was examined with a letter-matching task on four types of successively presented letter pairs: identical (A,A), visually confusable (P,R), auditorily confusable (F,S), and neither visually nor auditorily confusable (N,T). Two delay intervals (0 and 2 seconds) were used between the presentation of the first and second letters. Analysis of decision latencies on the nonidentical letter pair trials revealed that with initial exposure to the task, the SLDs responded more slowly than SCs, but their general confusability patterns (visual and auditory) were similar. With additional practice, overall decision latencies were comparable for the two groups, while confusability differences emerged: SCs showed maximal visual confusability at a 0-second delay and maximal auditory confusability at a 2-second delay, while SLDs did not. Evidently, SLDs make less extensive use of visual and auditory coding processes compared to SCs.

To study the possible role of plasma beta-endorphin in bulimia, we measured plasma beta-endorphin immunoreactivity in 34 female patients with normal-weight bulimia and 34 normal female controls matched for weight as percent of ideal. Plasma beta-endorphin immunoreactivity in bulimics (mean 59.6 pg/ml; SEM 5.6) was significantly lower (p less than 0.05) than in controls (mean 79.5 pg/ml; SEM 8.5). Within the bulimic group, plasma beta-endorphin immunoreactivity correlated inversely with severity of bulimic symptomatology as measured by the Eating Attitudes Test Bulimia Subscale (p less than 0.05). Endorphin level did not correlate with severity of depression or with percent ideal body weight. Abnormalities in opioid metabolism may be implicated in eating disorders and account for the addictive properties of these disorders.
