Dual Diagnosis
Historically
• In the 1970s it was thought that a minority of
clients suffered from both a mental illness and
an addiction
• Today, we know this is not true....
• Today we acknowledge that a majority of our
clients suffer from both a mental illness and an
addiction

Theories of DualDiagnosis
Self-medication theory: Substances are selectively used in
service of alleviating symptoms of mental illness (i.e. stimulant
abuse employed to counter the sedative effects of antipsychotic medications)
Alleviation of dysphoria: mental illness creates dysphoria
(feeling bad) and this dysphoria leads to drug use to mitigate
the experience of these unpleasant feelings
Multiple risk: In addition to the alleviation of bad-feelings, there
are additional risks such as: social isolation, poverty, lack of
daily structure, residing in areas with drug availability, history of
traumatic events
Theories Continued

Supersensitivity: individuals with severe mental illness
have biological/psychological vulnerabilities for substance
abuse caused by genetic and early environmental factors
that interact with life stressors
It is important to note that these theories might all be
present to varying degree’s in looking at the causal links
underlying a dual-diagnosis.
There are no definitive quantitative links correlating
mental illness/substance abuse apart from heavy
adolescent cannabis use and early onset schizophrenia
No Universal Agreed Upon
Definition
• Each disorder is intertwined with the other
• Each is able to influence the other (addiction magnifies)
• Chicken and Egg as far etiology
• Difficult to discern symptoms of one from psychiatric disorder
from the addictive disorder
• Many psychiatric symptoms omit once addiction is ceased or
after a period of abstinence
Stigma of the Dually
Diagnosed!
Likelihood that people with
mental illness will commit
violent acts
No greater than general
population!
Why worry about it?
• Have worse treatment outcomes
• Higher health care outcomes
• Increased risk of violence, trauma,
suicide, child abuse, neglect, involvement
with justice system
• More prone to helplessness, depression,
greater trouble coping

lifetime will have a mental illness

Problems in Working with
Dual Diagnosis Clients
• Fractured support systems
• Slow progress
• Off and on meds
• Significant level of denial
• Seeming inability to trust
• Collude and transference / idealization / or devalue
• Feelings on meds
• Field as a whole and turf wars
Dual-Diagnosis “Treatment”
•
•
•
The term “treatment” is a real set up because it points toward
a terminal end-point goal with the dually diagnosed and this, in
my experience, is simply not realistic.
There are some “approaches” and/or philosophies that have
emerged in working with the dual-diagnosed that have varying
degrees of efficacy
These approaches fall under: Serial Treatment, which treats
one condition first followed by the other
“Treatment” Continued
Parallel: These intervention approaches focus on both
substance abuse and mental illness treatment at the same
time
Integrated: Treatments are delivered at the same time (like the
parallel approach) but are coordinated by the same staff
team members in the same treatment setting
Biological: This is the psychotropic medication arm of treatment
and can be effective toward managing symptoms of mental
illness which in turn can facilitate treatment of substance
misuse
“Treatment” Continued

•
•
•
Social and Psychological: This is a broad spectrum term used to
describe therapeutic techniques such as:
Motivational Interviewing: Engaging in supportive and directed
conversation about individuals behaviors and patterns that are
designed to increase intrinsic motivation to change
Cognitive Behavioral: weakening connections between life stressors
and reactive/habitual responses that are negative and destructive.
Self-Help Groups: This includes many 12-step groups that can instill
peer support and self-discipline
