Substantial decrease of psychiatric comorbidity in chronic alcoholics upon integrated outpatient treatment - results...

Area of Science:

• Psychiatry
• Addiction Medicine
• Clinical Psychology

Background:

• Comorbidity in alcoholism treatment is not well understood.
• Chronic alcohol dependence often co-occurs with Axis I and Axis II disorders.
• Long-term treatment effects on these comorbidities require further investigation.

Purpose of the Study:

• To examine the course of comorbid Axis I disorders during two years of outpatient alcoholism treatment.
• To assess the impact of comorbid Axis I and II disorders on drinking outcomes over a four-year follow-up.
• To identify predictors of relapse in patients with severe chronic alcohol dependence.

Main Methods:

• Prospective study of 89 severely affected chronic alcohol-dependent patients.
• Psychiatric assessments at baseline, 6, 12, and 24 months of treatment.
• Drinking outcomes analyzed over a four-year follow-up period.
• Statistical analysis to determine remission rates and predictors of relapse.

Main Results:

• Comorbid Axis I disorders significantly remitted over two years of treatment (from 59.0% to 12.8%).
• Anxiety disorders showed slower remission, while mood disorders remitted early.
• The cumulative probability of not relapsing after four years was 0.59.
• Number of inpatient detoxifications and presence of personality disorders predicted poorer abstinence outcomes.

Conclusions:

• Comprehensive long-term outpatient alcoholism treatment leads to significant remission of comorbid Axis I disorders.
• Personality disorders, more than Axis I disorders, are strong predictors of long-term drinking outcomes.
• Integrated treatment addressing both substance use and personality disorders is crucial for improving abstinence rates.
