Mood disorders in opioid-dependent patients

Area of Science:

• Psychiatry
• Addiction Medicine
• Clinical Psychology

Background:

• Opioid dependence is a significant public health issue.
• Co-occurring mood disorders are common in individuals with substance use disorders.
• Understanding the prevalence of mood disorders in opioid-dependent outpatients is crucial for effective treatment.

Purpose of the Study:

• To determine the current prevalence of mood disorders among outpatients treated for opioid dependence.
• To identify specific types of mood disorders within this population.

Main Methods:

• A prevalence study design was employed.
• The study included 500 unpaid opioid-dependent outpatients voluntarily seeking treatment at private and government clinics.
• Diagnosis of mood disorders was assessed using the Research version of the structured clinical interview for DSM-IV Axis I Disorders (SCID-I).

Main Results:

• 67.2% of opioid-dependent outpatients were diagnosed with mood disorders.
• Substance-induced depression was the most common diagnosis (54.8%), followed by major depression (7.4%) and dysthymia (2.8%).
• The majority of participants reported long-term opioid use (over 5 years) and multiple attempts at abstinence.

Conclusions:

• High rates of mood disorders necessitate integrated psychiatric care for opioid-dependent individuals.
• Accessible and open psychiatric services are essential for patients voluntarily seeking treatment for opioid use disorder.
• Screening for and treating mood disorders should be a priority in addiction treatment programs.
