Background:
Adolescence is the most vulnerable development stage to start drug abuse in our country. Moreover, adolescent personality may be an individual risk factor for drug abuse.
Aim:
To characterize the personality of adolescent drug abusers using the Millon Adolescent Clinical Inventory (MACI) and its Chilean norms.
Patients And Methods:
Adolescents consulting in a mental health facility were studied. MACI was applied to 46 subjects, aged 16 +/- 1 years (30 males) with a history of drug abuse and compared with 58 peers aged 15 +/- 2 years (34 males) without such history.
Results:
Male and female drug abuser adolescents had a transgressor type of personality. Males had a high degree of sociability and unrestrained sexuality while females present signs of sexual abuse, suicide risk, and a more severe personality disorder.
Conclusions:
The personality traits detected in this group of drug abuser adolescents using Chilean norms is similar to those detected abroad and should help to plan rehabilitation.
