Hm. Pettinati et al., The relationship of axis II personality disorders to other known predictors of addiction treatment outcome, AM J ADDICT, 8(2), 1999, pp. 136-147
This study evaluated the prevalence of Axis II disorders in substance abuse
patients and the relationship between Axis II psychopathology and two othe
r known predictors of adverse addiction treatment outcomes, i.e., Axis I ps
ychiatric comorbidity and illegal drug use, specifically cocaine. 232 patie
nts with cocaine and/or alcohol dependence were admitted to either inpatien
t or outpatient addiction recovery programs at Carrier Foundation, a nonpro
fit, private-pay hospital in New Jersey. Axis II disorders were more preval
ent in cocaine than alcohol dependence and in patients with Axis I psychiat
ric comorbidity. When all three predictors were evaluated in one prediction
model, the combination of Axis I and II psychopathology was the best predi
ctor of a return to substance use at one year post-treatment, compared to t
he three factors alone. These findings highlighted the importance of the in
terrelationship of the relative prognostic value of three known predictors
of addiction treatment.
