Best Practices in Screening and Assessment for People with Co-Occurring Disorders

What Makes a Good Screening Tool

Good screening tools are designed to accurately identify both mental health and substance use disorders. Their effectiveness is often measured by sensitivity (ability to detect true positives) and specificity (ability to rule out false positives).

For example, the AC-OK Screen for Co-Occurring Disorders demonstrates over 90% agreement with other validated assessments, showcasing its reliability.

A strong screening tool strikes a balance between being thorough and practical. In busy clinical settings, it needs to gather enough information without being too time-consuming or resource-heavy.

Modern screening tools are even more effective when paired with digital platforms and standardized scoring systems. These features make it easier to interpret results consistently and provide actionable insights.

Accessibility is also critical. Tools should be easy to use, integrate seamlessly with digital health systems, and maintain clinical accuracy and security. When combined with clear, standardized protocols, such tools support reliable diagnoses and treatments across various clinical environments.

1. Addiction Severity Index (ASI)

The Addiction Severity Index (ASI) is a widely used tool for assessing co-occurring disorders. Created in the 1980s by A. Thomas McLellan and his team, this semi-structured interview remains a key resource in addiction evaluation.

The ASI examines seven key areas, each scored on a scale from 0 to 1:

These areas help provide a detailed picture of a person’s needs.

The ASI serves a dual purpose: it evaluates both substance use and mental health. The psychiatric section is particularly useful for identifying co-occurring disorders, paving the way for integrated care. Its standardized scoring ensures consistent results, with higher scores indicating greater severity and helping prioritize treatment.

While the ASI can be time-consuming, it offers several key benefits:

For accurate results, trained professionals must conduct the ASI interviews. The tool’s effectiveness depends on a consistent and thorough approach to gathering and interpreting information.

The latest ASI-6 version now also includes assessments for behavioral addictions, such as gambling.

2. Alcohol Use Disorder Identification Test (AUDIT)

The Alcohol Use Disorder Identification Test (AUDIT) was created by the World Health Organization (WHO) to screen for alcohol use disorders and related mental health issues. This 10-question tool examines three main areas: drinking habits, signs of dependence, and alcohol-related problems.

Here’s how the scoring works:

Compared to simpler tools like the CAGE questionnaire, AUDIT offers a more detailed look at drinking behaviors and related risks. Its structured scoring system makes it easier to assess risk levels across different healthcare settings.

AUDIT works especially well when paired with other mental health tools. For example, combining it with the Patient Health Questionnaire (PHQ-9) or the Generalized Anxiety Disorder scale (GAD-7) helps paint a fuller picture of a patient’s overall health and co-existing conditions.

Best practices for using AUDIT:

• Approach patients without judgment
• Be mindful of cultural differences
• Offer referrals when needed
• Stick to consistent scoring methods

AUDIT is widely used in primary care, emergency departments, and specialized treatment centers to catch alcohol-related issues early. By identifying at-risk individuals, it supports early intervention and helps prevent worsening alcohol use and mental health challenges.

Facilities like Ikon Recovery Center incorporate AUDIT into personalized treatment plans for dual-diagnosis care. This highlights its role in spotting issues early and supporting effective intervention strategies.

3. Patient Health Questionnaire (PHQ-9)

The PHQ-9 is a widely-used tool for identifying depression in individuals with co-occurring disorders. This nine-question survey assesses depressive symptoms over the past two weeks, giving clinicians a clear picture of a patient’s mental health.

Here’s how the PHQ-9 scoring system works:

This straightforward scoring system makes it an essential tool for assessing and managing depression, especially when paired with substance use screenings for a more complete understanding of co-occurring disorders.

Why PHQ-9 Stands Out

• Fast and efficient: Takes less than 5 minutes to complete.
• Accessible: Available in multiple languages to serve diverse populations.
• Validated: Proven effective across numerous clinical settings.
• Simple scoring: Ensures consistent and reliable interpretation.

These qualities make the PHQ-9 a practical choice for integrating into broader assessments, offering valuable insights for treatment planning.

How It’s Used

The PHQ-9 focuses on specific symptoms such as:

• Sleep disturbances
• Fatigue or low energy
• Difficulty concentrating
• Changes in appetite
• Thoughts of self-harm

For the best results, the questionnaire should be completed in a private, supportive setting where patients feel comfortable sharing openly. Regular follow-ups with the PHQ-9 can help track progress and refine treatment strategies.

When depression is identified alongside substance use issues, combining mental health counseling with substance use treatment is crucial. Facilities like Ikon Recovery Center use tools like the PHQ-9 to enhance dual diagnosis evaluations, ensuring precise treatment plans tailored to each individual’s needs.
