The Tridimensional Personality Questionnaire: an exploration of personality traits in eating disorders.
ABSTRACT The Tridimensional Personality Questionnaire (TPQ) was tested in four subgroups of eating-disorder patients: anorectic-restrictors (AN-R), anorectic-bulimics (AN-B), normal weight bulimics (BN), and bulimics with a past history of anorexia (B-AN). Normal controls and patients were matched for gender and age. All subjects completed the Beck Depression Inventory (BDI) in addition to the TPQ. AN-Rs scored lower on the Novelty Seeking scale than the bulimic groups and controls, and the two normal weight bulimic groups had higher Novelty Seeking scores than the controls. On the Harm Avoidance scale, all eating disorder groups scored significantly higher than the control group. In addition, the AN-Rs scored lower than the AN-Bs and B-ANs. The Harm Avoidance scale and depression scores were positively correlated while the Reward Dependence scale and depression scores were negatively correlated. Differences between diagnostic groups on the Novelty Seeking and Persistence scales remained clearly significant when depression was partialled out. These results are discussed in terms of the Tridimensional Personality Questionnaire as a stable measure of traits with eating disorder subjects.

ABSTRACT: This article reviews the current literature on ‘disturbed eating patterns’, particularly anorexia nervosa (AN) and bulimia nervosa (BN) and the relationship between these two eating disorders and life stress, coping styles, social support and personality factors. The article sets out to describe how these psychosocial factors interact and the possible role they play in eating disturbance. Three possible models of the stress process and its relationship to disordered eating behaviour are proposed. Copyright © 1999 John Wiley & Sons, Ltd.Stress Medicine 07/1999; 15(3).

ABSTRACT: Although suggested as an important contributor to the development and maintenance of eating disorders, temperament has not previously been studied adopting a meta-analytical approach. We therefore pooled data (N = 14 studies; N = 3315 cases, N = 3395 controls) on Cloninger's temperament traits (novelty seeking, harm avoidance, reward dependence and persistence) in anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED) and eating disorders not otherwise specified. Persistence was significantly higher than in the controls in all eating disorders except for BED the highest levels being observed in AN. Correspondingly, the highest effect sizes for harm avoidance were seen in AN. Novelty seeking was significantly elevated relative to the controls only in BN. Harm avoidance was significantly lower, and reward dependence was significantly higher in individuals who had recovered from AN than in those who remained ill. Future studies with a longitudinal design are needed to explore the temporal relationships between eating disorders and temperament traits.
