METHOD
Sample
Recruitment.
An anger
management group
treatment was
delivered in
conjunction with
two substance
abuse treatment
programs. Men
received
substance abuse
treatment at the
Substance Abuse
Outpatient
(SAOP) Clinic at
San Francisco
Veterans Affairs
Medical Center.
Women received
substance abuse
treatment at the
Stimulant
Treatment
Outpatient
Program (STOP)
at San Francisco
General
Hospital.
Potential
participants
were recruited
for the study if
they met the
inclusion
criteria of
cocaine
dependence
according to the
Diagnostic and
Statistical
Manual of Mental
Disorders (7)
and if they
reported
problems
controlling
their anger.
Initial
diagnoses were
made by intake
clinicians at
the treatment
programs and
were verified by
a clinical
psychologist.
Participants
were excluded if
they had medical
or psychiatric
problems that
were so severe
that
hospitalization
was expected
within the
6-month study
period, were
diagnosed by
staff as having
schizophrenia or
organic brain
dysfunction,
planned to leave
the San
Francisco Bay
Area within 6
months, or
anticipated jail
time within that
period.
Study
investigators
recruited
patients from
early cocaine
dependence
treatment groups
at the two study
sites.
Interested
patients
attended an
orientation
session at which
the
investigators
explained study
procedures,
obtained
informed
consent, and
determined
eligibility for
the study.
Ninety-one
patients
consented and
attended a
12-week anger
management group
treatment.
Treatment groups
began when at
least 5
participants
meeting the
study criteria
had been
recruited.
Participants
waited between 1
and 6 weeks for
their group to
form. Seven
cohorts of men
and four cohorts
of women were
recruited. The
mean size of the
cohorts was 8.27
(SD = 2.83)
participants.
Demographics.
The sample
consisted of 59
men and 32
women. Men and
women did not
differ on
baseline levels
of anger,
negative affect,
or drug use (all
t values [is
less than]
1.50). Men were
significantly
older than
women, with a
mean age of 44.3
(SD = 7.22)
years versus a
mean of 36.4 (SD
= 5.31) years (p
= .02). Of the
91 participants,
53 (58%) were
African-American,
28 (31%)
Caucasian, 5
(6%) Hispanic, 3
(3%) Asian, and
2 (2%) from
other ethnic
groups. There
were 29 (32%)
participants who
reported taking
medication for a
psychiatric
problem at
baseline.
Drug use
history. There
were 67 (74%)
participants who
reported that
they did not use
any substance 30
days prior to
baseline, which
was expected
considering that
all participants
were enrolled in
substance abuse
treatment
programs. Also,
4 (4%)
participants
reported alcohol
use only 30 days
prior to
baseline; 5 (6%)
used cocaine
only; 1 (1%)
used heroin
only; 3 (3%)
used alcohol and
marijuana; 3
(3%) used
cocaine and
alcohol; 2 (2%)
used alcohol,
cocaine, and
marijuana; and 6
(7%) did not
provide a
response. Only 2
participants who
used drugs or
alcohol reported
7 or more days
of drug or
alcohol use
during the 30
days prior to
baseline.
