The role of temperament and character in the outcome of depressive mood in eating disorders

Abstract

Objectives: The aims were to see which temperament and character dimensions were associated with depression, mainly with its outcome at two-year follow up in eating disorders (EDs).

Methods: Participants (N=151) were 44 Anorexia nervosa (AN), 55 Bulimia nervosa (BN) and 52 Eating disorders not otherwise specified (EDNOS) patients. The Beck Depression Inventory (BDI), State and Trait Anxiety Inventory (STAI), Rosenberg Self Esteem Questionnaire (RSE), Eating Disorder Inventory (EDI-2) and Temperament and Character Inventory (TCI) were administered.

Results: Depression at the beginning (t0) was severe in 22% of the cases. Harm Avoidance and Novelty Seeking had an effect on depressed mood at t0, mediated by Ineffectiveness. Responsibility (SD1) was associated with scores on the BDI at two-year follow up (β=-0.37, 95% CI -2.6, -0.6, p<0.01).

Conclusion: The evaluation of personality dimension in EDs has therapeutic and prognostic implications: To enhance self-efficacy and self-directness is crucial for good clinical outcome.
