Prevention Issues
Lifetime Patterns of Substance Use
and Abuse: Focus for Prevention
Strategies
Higher
Older
Prevention of Substance Abuse Among
Older Adults: Conceptual Issues
Age group definitions
 Life course variations in consumption
 Sensible/appropriate use of alcohol and
prescription drugs
 Diagnostic criteria for abuse/dependence
 Risk profiles for specific subpopulations
 Prevention goals

Prevention Strategies Effective with
Youth: Relevance to Older Adults





Individual-Focused: education, skills development,
alternate behaviors, health behaviors
Families/Social Support: spousal interventions,
family supports, caregivers
Peer Norms: network of friends, perceptions
Organizations: health care organizations, AARP,
other policy changes
Social Environment: social norms and policies,
availability and sanctions
Prevention of Substance Abuse Among
Older Adults: Additional Issues


Access to target populations
Optimal modality for materials
Appropriateness and acceptability of
content
Delivery systems
Program-driven vs. research-initiated
interventions
Policy interventions
Role of drinking, prescription drugs in late
life
Risk and Protective Factors
Prevention of Substance Abuse Among
Older Adults: Risk Factors







Male
Racial/Ethnic Minority Status
Psychiatric Comorbidity
Higher SES
Lower Social Supports
Previous History of Problems
History of Using Substances as Coping Strategy
Prevention of Substance Abuse Among
Older Adults: Protective Factors
Female
 Higher Religiosity
 Fewer Mental/Physical Health Problems
 Lower SES
 Positive Coping Styles
 More Social Supports

Diagnosis Issues
Problems with Definitions
Substance Misuse
 At-risk or Hazardous Use
 Problem Use
 Substance Abuse
 Substance Dependence

Diagnostic Criteria
for Substance Dependence
in Older Adults
The Treatment Improvement Protocol
(TIP #26) Consensus Panel determined:
DSM-IV criteria for substance abuse
and dependence may not be
adequate to diagnose older adults
with substance use problems
DSM-IV Dependence Criteria
Tolerance
 Withdrawal
 Use in larger amounts or for longer than intended
 Desire to cut down or control use
 Great deal of time spent in obtaining substance
or getting over effects
 Social, occupational, or recreation activities
given up or reduced
 Use despite knowledge of physical or
psychological problem

Applying DSM-IV Criteria
to Older Adults
Tolerance
Even low intake may cause
problems due to body changes
Withdrawal
May not develop physiological
dependence
Use in larger amounts or for longer
than intended
Cognitive impairment interferes
with self-monitoring
Desire to cut down or control use
Same across life span
Time in obtaining substance or
getting over effects
Negative effects with relatively
low use
Activities given up or reduced
May have fewer activities
Use despite knowledge of problems
May not know problems are
related to use
Screening
Practitioner Barriers
to Identification
Ageist
assumptions
Failure to recognize symptoms
Lack of knowledge about screening
Physician discomfort with substance abuse
topic
- 46.6% of primary care physicians found it
difficult to discuss prescription drug abuse with
their patients
(CASA, 2000)
Individual Barriers
to Identification
Attempts
at self-diagnosis
Description of symptoms attributed to aging
process or disease
Many do not self-refer or seek treatment
- Although most older adults (87 percent) see
physicians regularly, an estimated 40 percent of
those who are at risk do not self-identify or seek
services for substance abuse
(Raschko, 1990)
Signs and Symptoms of Substance
Use Problems in Older Adults










Anxiety
Blackouts, dizziness
Depression
Disorientation
Mood swings
Falls, bruises, burns
Family problems
Financial problems
Headaches
Incontinence







Increased tolerance
Legal difficulties
Memory loss
New problems in decision
making
Poor hygiene
Seizures, idiopathic
Sleep problems
Social isolation
Unusual response to
medications
Symptom Identification


Applying quantity and frequency levels
appropriate for younger adults to elders may cause
failure to identify substance use problems
Warning signs can be confused with or masked by
concurrent illnesses and chronic conditions, or
attributed to aging
– Sleep problems associated with chronic conditions,
particularly cardiovascular disease and pain
– Falls attributed to poor lower body strength, poor
balance, or vision limitations
– Anxiety attributed to psychosocial concerns
– Confusion/memory problems associated with
Alzheimer’s disease or other dementias
Psychosocial Manifestations of
Mild/Moderate Drug Disorders

Psychological/Behavioral
– Agitation, irritability, dysphoria, difficulty in coping,
mood swings, hostility, violence, psychosomatic
symptoms, hyperventilation, generalized anxiety, panic
attacks, depression, psychosis

Family
– Chronic stable family dysfunction, marital problems,
anxiety and depression in family members, divorce,
abuse and violence
(Brown, 1992)
Psychosocial Manifestations of
Mild/Moderate Drug Disorders

Social
– Alienation and loss of old friends, gravitation toward
others with similar lifestyle

Legal
– Arrests for disturbing the peace or driving while
intoxicated, stealing, drug dealing

Financial
– Borrowing or owing money, selling personal or family
possessions
(Brown, 1992)
Screening Instruments

Modified CAGE for drug abuse
– Examined for older populations (50 and over)
– Excellent sensitivity, poor specificity
(Hinkin et al., 2001)

Conjoint two-item screen
– "In the past year, have you ever drunk or used drugs
more than you meant to?"
– "Have you felt you wanted or needed to cut down on
your drinking or drug use in the past year?"
» Ages 50-59: Sensitivity 73.9, Specificity 84.8
(Brown et al., 2001)

Screening and Assessment
Recommendations for Older Adults

Every person over 60 should be screened
for alcohol and drug abuse as part of regular
physical examination
 “Brown Bag Approach”

Screen or re-screen if certain physical
symptoms are present or if the older person
is undergoing major life transitions
Screening and Assessment
Recommendations for Older Adults

Ask direct questions about concerns
 Preface question with link to medical
conditions of health concerns
 Do not use stigmatizing terms (i.e. drug addict)
Future Directions
 Risk and Protective Factors/Prevention/Early
Identification
 Drug of Choice
• Illicit, Prescription, Alcohol
 Patterns of use
• Drug use trajectories
• Re-emergence of addiction in late life
• Late-life onset of substance use disorder
 Screening, Assessment and Diagnosis
 Identification and treatment of psychiatric
comorbidities
