Major Subgroups of Major Subgroups of Comorbid ClientsComorbid Clients
• Severely mentally ill - psychotic Frequently abuse moderate amounts of
substances Small amounts of substance use trigger
negative consequences
• Anxiety and/or depression Substance use can cause or worsen
symptoms
Frequently abuse moderate to high amounts of substances
• Personality Disorders Antisocial & borderline most common Frequently abuse high amounts of
substances
Clinical EpidemiologyClinical Epidemiology
11. . Rates higher for people in treatment
22.. Approximately 50% lifetime, 25% 35% current substance abuse
33.. Rates are higher in acute care, institutional, shelter, and emergency settings
44.. Substance abuse is often missed in mental health settings
Why Focus on Dual Why Focus on Dual Disorders?Disorders?
11.. Substance abuse is the most common co-occurring disorder in persons with severemental disorders
22.. Significant negative outcomes related to substance abuse:
1) Clinical relapse & rehospitalization2) Demoralization
3) Family stress
4) Violent behavior
1) Incarceration2) Homelessness3) Suicide 4) Medical illness 5) Infections diseases6) Early mortality
3.3. Outcomes improve when substance abuse remits
4.4. Poor treatment is expensive for families and society
Reasons for High Reasons for High Comorbidity Rates of Severe Comorbidity Rates of Severe Mental Illness and Substance Mental Illness and Substance
AbuseAbuse• Berkson’s Fallacy• Self-medication*• Super-sensitivity to effects of
substances*• Socialization motives• Precipitation of psychosis from
substance use
• Common factors Poverty/deprivation Neurocognitive impairment Conduct disorder/antisocial
personality disorder
Self-MedicationSelf-Medication:: More symptomatic clients don’t abuse
more substances Substance selection unrelated to type of
symptoms experienced Types of substances abused unrelated to
psychiatric diagnosis Self-medication may contribute to some
comorbidity but doesn’t explain all More evidence supporting self-medication
in anxiety disorders (PTSD)
Super-sensitivity ModelSuper-sensitivity Model:: Biological sensitivity increases vulnerability to
effects of substances Smaller amounts of substances result in
problems “Normal” substance use is problematic for
clients with severe mental illness but not in general population
Sensitivity to substances, rather than high amounts of use, makes many clients with mental illness different from general population

Support for Super-sensitivity ModelSupport for Super-sensitivity Model:: Dual disorder clients less likely to develop physical
dependence on substances Standard measures of substance abuse are less
sensitive in clients with severe mental illness Clients are more sensitive to effects of small
amounts of substances Few clients are able to sustain “moderate” use
without impairment Super-sensitivity accounts for some increased
comorbidity
Overview of Assessment Overview of Assessment of Substance Abuse in of Substance Abuse in
Clients with Severe Clients with Severe Mental IllnessMental Illness
Detection
Classification
Functional Assessment
Functional Analysis
Treatment Planning
• Psychological DependencePsychological Dependence - - Use of more substance than intended, unsuccessful attempts to cut down, giving up important activities to use substances, or spending lots of time obtaining substances.
• Physical DependencePhysical Dependence - - Development of tolerance to effects of substance, withdrawal symptoms following cessation of substance use, use of
substance to decrease withdrawal symptoms.
Functional AssessmentFunctional Assessment• GoalsGoals:: To understand client’s functioning
across different domains and to gather information about substance use behavior
• Domains of FunctioningDomains of Functioning
1. 1. Psychiatric disorder
2.2. Physical health
3.3. Psychosocial adjustment (family & social relationships, leisure, work, education, finances, legal problems, spirituality)
• Dimensions of Substance AbuseDimensions of Substance Abuse1.1. 6-Month Time-Line Follow-Back
Calendar2.2. Substances abused & route of administration3.3. Patterns of use4.4. Situations in which abuse occurs5.5. Reported motives for use
• Social• Coping• Recreational• Structure/sense of purpose
6.6. Consequences of use
Evaluating Social FactorsEvaluating Social FactorsAssociated with Associated with
Substance AbuseSubstance Abuse• Does person have non-substance abusing
peers?• Can person resist offers to use substances?• Is the person lonely?• Can the person initiate and maintain
conversations?• Is person able to get others to respond
positively to him/her?• Can the person express feelings? Resolve
conflicts?
Common Symptoms Common Symptoms AssociatedAssociated
with Self-Medicationwith Self-Medication
• Depression, suicidal thoughts• Anxiety, nervousness, tension• Hallucinations• Delusions of reference & paranoia• Sleep disturbance• Mania/hypomania
Recreational Skills and Recreational Skills and Substance AbuseSubstance Abuse
• What does the person do for fun?• Hobbies?• Sports?• What is person’s involvement with
others in recreational activities?• Does the person not participate in
activities which he/she previously did?
Functional AnalysisFunctional Analysis• GoalGoal:: To identify factors which influence or control
substance use behavior• Characteristics of Useful Functional AnalysesCharacteristics of Useful Functional Analyses
1. 1. Focus on behaviors, NOT stable traits2.2. Constructive, NOT eliminative3.3. Contextual, NOT mechanistic4. 4. Examines maintaining factors, NOT etiological
factors5.5. Leads to hypotheses that can be tested by
treatment & modified, NOT theories that remain unchanged regardless of outcome
6.6. Change usually doesn’t happen magically on its own
•Constructing a Payoff MatrixConstructing a Payoff Matrix1. 1. List advantages & disadvantages of using
substances, & advantages & disadvantages of not using substances in Payoff Matrix
2.2. Use all available information from functional assessment
3.3. Consider advantages & disadvantages from theclient’s perspective
4. 4. View different reasons listed as hypothesesabout maintaining factors, not establishedfacts; reasons may change as new informationemerges
5.5. If client is using, the pros of using & cons ofnot using should outweigh the pros of notusing and cons of using

Treatment PlanningTreatment Planning
• GoalsGoals: : To determine which interventions are most likely to be effective and how to measure outcome
• StepsSteps
1. 1. Engage the client and significant others
2.2. Assess motivation to change
3.3. Select target behaviors, thoughts, emotions to change
4.4. Identify interventions to address targets: select at least 1 strategy to
enhance motivation & 1 strategy to address needs currently met by substance use
5.5. Choose measures to assess effects of intervention
Treatment BarriersTreatment Barriers
• Historical division of service and training
• Sequential and parallel treatments• Organizational and categorical funding
barriers in the public sector• Eligibility limits, benefit limits, and
payment limits in the private sector
Integrated TreatmentIntegrated Treatment
• Mental health and substance abuse treatmentDelivered concurrentlyBy the same team or group of
cliniciansWithin the same programThe burden of integration is on
the clinicians

Research on Integrated Research on Integrated Treatment (IT)Treatment (IT)
• 26+ RCT or quasi-experimental studies of IT (reviewed by Drake et al., 2004)
• 3/4 studies of brief motivational interviewing interventions showed positive effects
• 6/7 studies found group intervention better than 12-step or standard care
Research on IT (Cont.)Research on IT (Cont.)
• Family intervention: no RCTs examining family treatment alone
• Comprehensive IT: 2 RCT & 1 quasi-exp. study favor comp. IT over treatment as usual
• Intensity: more intensive IT produces slightly better outcomes (e.g., Drake et al., 1998)
Drake et al. (1998)Drake et al. (1998)
• 203 clients (77% schizophrenia)• ACT vs. standard case management (SCM)
(both IT)• 3 year follow-up• ACT better than SCM in alcohol severity &
stage of treatment• No differences in hospitalization, symptoms,
quality of life

Avoiding the Avoiding the Blame/Demoralization Blame/Demoralization
TrapTrapDon’t blame the client for substance Don’t blame the client for substance
abuse or relapses because:abuse or relapses because: Substance abuse is a disorder for which
clients are no more responsible than their primary psychiatric symptoms
Clients with most severe substance abuse need professional help the most; many others improve spontaneously
Remember that the clients are doing the best they can
To avoid demoralizationTo avoid demoralization:: Remember: integrated treatment works in
the long run There is usually no obvious “best solution” Adopt a collaborative-empirical approach to
treatment View relapses as an inevitable part of the
recovery process Develop a case formulation based on a
functional analysis to guide treatment
