What treatment approach is recommended for a younger to middle-aged adult with a history of substance use disorder and psychological factors, as per DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) diagnosis, but no formal psychiatric diagnosis?

Treatment Approach for Psychological Factors Without Formal Psychiatric Diagnosis in Substance Use Disorder

Immediate Clinical Action

Even without a formal psychiatric diagnosis, psychological factors (DSM-5 diagnosis) in the context of substance use disorder warrant integrated treatment addressing both the substance use and psychological symptoms concurrently. 1

Understanding the Diagnostic Context

• The American Psychiatric Association's DSM-5 eliminated the abuse/dependence distinction and created a single substance use disorder diagnosis requiring 2 or more of 11 criteria, with severity specifiers (mild: 2-3 criteria; moderate: 4-5 criteria; severe: 6+ criteria). 2, 3

• Psychological factors without a formal psychiatric diagnosis may represent:

  • Substance-induced symptoms that resolve within 4 weeks of abstinence 1, 4
  • Subthreshold psychiatric symptoms that don't meet full diagnostic criteria but still cause distress
  • Early manifestations of co-occurring mental health conditions requiring monitoring

Treatment Framework

Psychotherapeutic Interventions (First-Line)

• Cognitive Behavioral Therapy (CBT) should be the primary psychotherapy approach, as it has strong evidence for both substance use disorders and psychological symptoms including depression and anxiety. 1

• Additional evidence-based psychotherapies include:

  • Motivational enhancement therapy 1
  • Behavioral activation 1
  • Interpersonal therapy 1
  • Problem-solving therapy 1

• Treatment should emphasize psychoeducation, establishing a strong therapeutic relationship, and maintaining flexibility regarding methods and goals. 5

Pharmacological Considerations

• For the substance use disorder component, consider FDA-approved medications:

  • Naltrexone, acamprosate, or disulfiram for alcohol use disorder 1
  • These medications reduce cravings and maintain abstinence 1

• For psychological symptoms, antidepressant medication (SSRIs or SNRIs) may be considered if symptoms are clinically significant and persist beyond the acute withdrawal period. 1, 4

• Critical caveat: Patients with substance use disorder history require intensive counseling about risks and proper medication use, with frequent reevaluation for signs of misuse. 6

Integrated Care Model

• The American College of Physicians recommends treating substance use and psychological symptoms concurrently by the same treatment team, which demonstrates superior outcomes compared to sequential or parallel treatment. 1

• Continuous reassessment of psychological symptoms during substance use disorder treatment is necessary to differentiate substance-induced symptoms (which resolve with abstinence) from independent conditions requiring ongoing treatment. 1, 4

Treatment Intensity Determination

More intensive settings (inpatient or residential) are indicated for:

• Severe substance use disorder (6+ DSM-5 criteria) 2
• Suicidal ideation 1
• Poor social support 1
• Previous treatment failures 1

Outpatient treatment is appropriate for:

• Mild to moderate substance use disorder with adequate social support
• Absence of acute safety concerns
• Ability to engage in regular treatment sessions

Monitoring Strategy

• Temporal assessment is critical: Evaluate whether psychological symptoms preceded substance use, occur only during intoxication/withdrawal, or persist beyond 4 weeks of abstinence. 1, 4

• Use validated assessment tools:

  • PHQ-9 for depressive symptoms 1
  • Standardized alcohol/substance use assessments 1

• Reassess at regular intervals (weekly initially, then monthly) to determine if symptoms resolve with abstinence or require escalation to formal psychiatric diagnosis and treatment. 1, 4

Critical Pitfalls to Avoid

• Do not delay treatment waiting for formal psychiatric diagnosis—psychological factors alone warrant intervention in the context of substance use disorder. 1

• Avoid benzodiazepines for anxiety symptoms outside of acute withdrawal management, as they carry significant risk of respiratory depression and addiction when combined with substance use disorders. 6

• Do not assume all psychological symptoms are substance-induced—some may represent independent conditions requiring specific treatment even if they don't meet full diagnostic criteria. 1, 4

• Avoid confrontational approaches—address consequences of behaviors in a non-confrontive style while maintaining pragmatic flexibility regarding treatment goals. 5
