.the family socioeconomic status in children and adolescents through
four questions. The sum of the scores for each response provides a
number that allows to classification of the subject into a high (score
from 6 to 9), medium (score from 3 to 5) or low (score less than 3)
socioeconomic status. The “Health” section involved questions about
diseases and the health status of the subjects, and the “Welfare” section
consisted of questions regarding mental health. The participants
were asked about psychiatric assessment or treatments received and
psychiatric disorders diagnosed. We used the “Standardized Assessment
of Personality-Abbreviated Scale” (SAPAS) as the screening method to
identify personality disorders. This test consists of 8 questions with
a score “0/1”. A total of 3 points in the interview correctly identifies
(sensitivity 94% and specificity 85%) the presence of personality
disorders according to the Diagnostic and Statistical Manual of Mental
Disorders IV (DSM-IV) [15]. For the assessment of ADHD we used
the “Adult ADHD Self-Report Scale (ASRS-v1-1) symptom checklist”,
a WHO self-administered scale that assesses the frequency of the 18
ADHD symptoms described by the DSM-IV [16]. In the last section,
relating to drug use, the participants were asked about the use of
cannabis, cocaine, heroin, benzodiazepine, liquid ecstasy, ecstasy,
amphetamine, and hallucinogens. The Fast Alcohol Screening Test
(FAST) was used to screen use/abuse of alcohol. This test consists of 4
questions, resulting in a score between 0 and 16. If the total score is 3 or
more, the patient is considered a hazardous drinker with a sensitivity of
93% and a specificity of 88%[17].
