and a poly-drug excessive drinking and smoking group, on an objec-
tive measure of PM.
Methods A between-subjects design will be used to compare
three groups: (1) a group of excessive drinkers who do not smoke;
(2) a group of smokers who do not drink excessively and (3) a group
of excessive drinkers who also smoke. The Cambridge Prospec-
tive Memory Task will measure both time and event based PM;
and two self-reports will measure covariates of substance use and
everyday mood (since these can impact upon PM independent of
smoking/drinking status).
Results Descriptive statisticswill be applied to observe the trends
across all three groups with regards the covariates andmain depen-
dent measures of time and event based PM. A series of ANOVAs
will be applied to determine significance across the groups on the
covariates and on the main dependent measures.
Conclusions The conclusions and implications will be presented
at the conference, along with suggestions for future research.

Introduction Substance related disorders is a problem of global
concern because of the high prevalence and costs for patients and
society. In one of the latest surveys, 52% of the American popu-
lation reported being current alcohol drinkers and 6.3% admitted
being heavy drinkers. In addition, 9.4% are illicit drug users, being
marijuana the most commonly used.
Objectives To determine whether there is a relation between the
substance of abuse and the demographic characteristics, medical
and psychiatric comorbidities of patients with substance use dis-
order.
Patients and methods This correlational study examined data
of 218 patients with substance use disorder (DSM-5), that con-
sulted at the Addiction Unit of “Red de Salud, Pontificia Universidad
Católica de Chile”, between April 2012 and September 2015. Data
included: demographics, medical and psychiatric history, labora-
tory and imaging tests.
Results Out of all the patients, 57% suffered from alcohol use dis-
order, whereas 21% abused of marijuana, 20% of cocaine and 8% of
benzodiazepines. There was a correlation between alcohol use dis-
order and being over 40 years of age, being separated and having
higher educational studies. For marijuana, being under 40 years of
age, being single and having no medical comorbidities. For cocaine,
not being single. For benzodiazepines, being over 40 years of age,
being separated and having medical comorbidities. All of these cor-
relations were statistically significant.
Conclusion These results emphasize on the complexity of these
patients and on the important contrast created between age,
marital status, level of education and prevalence of comorbidity
depending on the abused substance.

Introduction Over the past two decades the prescription of opioid
analgesics has increased with a subsequent escalating in prescrip-
tion opioid misuse. It is estimated that 4.5 million (2.5%) of the
United States of America population abuse of pain relievers; opioids
are among the most commonly.
In Chile there are few reports about the prevalence of opioid use
disorder.
Objectives The aim of this study is to describe the demographic
characteristics, medical and psychiatric comorbidity of patients
that suffer from opioid addiction.
Patients and methods This transversal study examined data of 7
patients with opioid use disorder (OUD; DSM-5) that consulted
at the addiction unit of “Red de Salud, Pontificia Universidad
Católica de Chile”, betweenNovember 2013 andOctober 2015. Data
included: demographics, medical and psychiatric history, labora-
tory and imaging tests.
Results Of all the patients, 57% were men, 25 to 67 years of
age, 43% between 35-40 years; 57% were married; 57% had com-
pleted studies at university. 43% had also alcohol use disorder,
28% marijuana, 28% cocaine and 28% benzodiazepines than in most
cases began before OUD. In addition; 57% had medical comorbid-
ity among which stand out obesity (17%), osteoarthritis (17%) and
chronic low back pain (17%). Eighty-three percent require hospi-
talization. Twenty-eight percent had abnormal liver tests and one
patient had positive hepatitis B core antibody. Opioids used were:
morphine(14%), codeine (43%), tramadol (42%).
Conclusion These results emphasize on the misuse of prescrip-
tion opioids analgesics, the complexity of patients with OUD and
the prevalence of other substance use disorder that precedes and
accompany OUD.

Introduction Quality of Life (QoL) is an important outcome vari-
able in Methadone Maintenance Treatment (MMT) for opiate
dependence. Previous research has focused on demographic vari-
ables, treatment features, drug use and physical and mental health
as possible predictors of QoL in this condition but interest in gen-
uinely psychological variables (skills and personal repertoires) has
been lacking. Experiential Avoidance (EA), the tendency to behave
in order to decrease some kind of internal distress, has a strong rela-
tionship to psychological disorders and holds promise as a potential
predictor of QoL.
