Cm. Bulik et al., TEMPERAMENT, CHARACTER, AND PERSONALITY-DISORDER IN BULIMIA-NERVOSA, The Journal of nervous and mental disease, 183(9), 1995, pp. 593-598
In a sample of 76 women participating in a clinical treatment trial fo
r bulimia nervosa, we examined the clinical differences between subjec
ts with and without concurrent personality disorders and the ability o
f ''self-directedness'' (a character scale of Cloninger's Temperament
and Character Inventory) to predict the presence of personality disord
er. Sixty-three percent of the sample had at least one personality dis
order diagnosis. Fifty-one percent of personality disorders were in cl
uster C, 41% were in cluster B, and 33% were in cluster A. The presenc
e of personality disorder was associated with greater depressive sympt
oms, worse global functioning, laxative use, greater body dissatisfact
ion, higher harm avoidance, and lower self-directedness. As hypothesiz
ed, low self-directedness scores were associated with a markedly incre
ased probability of a personality disorder.
