Summary
The computer-assisted Composite International Diagnostic Interview (CIDI-Auto) demonstrates reliable alcohol and substance abuse diagnoses across different countries and languages. This diagnostic tool shows good reliability for classifying substance use disorders.
Area of Science:
- Psychiatry and Mental Health
- Epidemiology
- Clinical Psychology
Background:
- Accurate diagnosis of alcohol and substance abuse disorders is crucial for effective treatment.
- The Composite International Diagnostic Interview (CIDI) is a widely used diagnostic instrument.
- Computer-assisted versions aim to improve efficiency and standardization of diagnostic interviews.
Purpose of the Study:
- To evaluate the test-retest reliability of the Alcohol and Substance Abuse modules of the CIDI-Auto.
- To assess reliability across different countries (Australia, Puerto Rico) and languages (English, Spanish).
- To examine reliability at both the diagnostic and symptom levels for DSM/ICD criteria.
Main Methods:
- The study involved 286 participants (ages 17-60) with a history of alcohol consumption.
- Test-retest reliability was assessed for the CIDI-Auto using kappa statistics.
- Analyses were conducted across different nosologies, study sites, substances, and time intervals.
Main Results:
- Adequate to good test-retest reliability estimates were achieved for the CIDI-Auto modules.
- Reliability was consistent across different settings, languages, and substances.
- Dependence showed higher reliability (kappa: 0.70-0.95) compared to harmful use/abuse (kappa: 0.45-0.66).
Conclusions:
- The CIDI-Auto provides reliable classifications for alcohol and substance abuse disorders.
- Its reliability is maintained across diverse cultural and linguistic contexts.
- The instrument demonstrates good coverage of various manifestations of substance use disorders.
