AbstractCognitive-behavioral therapy (CBT) is a successful treatment method for reducing symptomatology associated with bulimia nervosa (BN). Less is known regarding the impact of CBT on measures of temperament and character across treatment. We explore changes on the Temperament and Character Inventory (TCI) from pretreatment to 1-year follow-up in a sample of women with bulimia nervosa (BN). Ninety-one women who met DSM-III-R criteria for BN, completed pretreatment measures, and participated in a randomized clinical trial with a core treatment of CBT were available for follow-up at 1 year. Participants were assessed at pretreatment using the TCI as part of a larger assessment battery, and received eight sessions of CBT and eight sessions of exposure with response prevention or relaxation training. The TCI was readministered at the 1-year follow-up point. We compared TCI scores across the two administrations and explored the relation between clinical status at 1 year and TCI scores. Significant decreases in the TCI temperament scale of harm avoidance and increases in the character scale of self-directedness were observed between pretreatment and 1-year follow-up. Observed differences in these scales were independent of change in depression scores as well as other measures of therapeutic change (i.e., binge and purge frequency). We conclude that self-directedness and harm avoidance scores are positively affected by CBT. Higher scores on self-directedness not only predict treatment outcome for BN, but overall self-directedness is improved with CBT in women with BN. These results suggest that the elements of CBT affecting self-directedness may hold promise for enhancing the effectiveness of treatment for BN.Copyright 2002, Elsevier Science (USA).
