We examined differences between personality characteristics of euthymic bipolar disorder patients (BD) (n = 34) and recovered unipolar depressed patients (UD) (n = 74) using the taxonomy of the Five-Factor Model of personality (FFM) as measured by composite scales derived from the NEO Personality Inventory (NEO PI) and the revised NEO PI (NEO PI-R). Euthymic BD patients scored significantly higher on the Openness (O) dimension and the Positive Emotions facet of the E dimension than did recovered UD patients. For O, euthymic BD patients scored higher on the Feelings facet. These results suggest not only that euthymic BD patients are more likely to experience positive affects than recovered UD patients, but also that euthymic BD patients are more receptive to their positive and negative feelings than are recovered UD patients.
