For veterans navigating the VA disability for mental health conditions, then the Global Assessment of Functioning (GAF) score is not new to you.
For years, it has been VA’s system for evaluating the veteran’s functional capacity if they were diagnosed with a mental health condition.
We are now living in an age where the majority of the world population is getting a deeper understanding of the importance of mental health, and as a way to modernize how they evaluate mental health-related disabilities, the VA will now use a new evaluation method—WHODAS 2.0.
Veterans across the country are seeing their disability ratings affected by this updated method of assessment. If you’re filing your first claim or seeking a reassessment, understanding how WHODAS 2.0 works—and how to prepare— is critical. You can also seek out our VA claim consulting service for educational coaching assistance to make sure you have all the information you need to claim any benefits.
Understanding GAF and WHODAS 2.0
GAF was once the standard for assessing mental health for the VA disability measurement scale. Some mental health conditions were rated on your overall psychological, social, and occupational functioning.
However, some changes need to be implemented since there are some serious limitations in its process.
Some raise concerns about its overall lack of consistency, objectiveness, and even the details required to allay the veteran’s concern of whether they are being assigned with the proper VA rating.
In pursuit of remedying this issue the VA will now use the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0). This assessment will offer more standardization and measures of health and disability across six core domains.
- Cognition (understanding & communicating)
- Mobility
- Self-care
- Getting along with people
- Life activities (work, household)
- Participation (community involvement)
Compared to GAF score, WHODAS 2.0 offers a structured, standardized way to measure how mental health conditions actually affect your daily life. It aligns its process with the International Classification of Functioning (ICF), to make it a more globally accepted disability measurement scale.
Comparative Analysis: GAF vs. WHODAS 2.0
WHODAS 2.0 was introduced as a replacement for GAF after the DSM-5 removed GAF scoring due to its lack of reliability. Here’s a quick comparison:
| Criteria | GAF | WHODAS 2.0 |
| Subjectivity | High | Low – Uses structured questions |
| Scope | Mental health focus only | Broader – Includes Physical Limitations |
| Scoring System | 0-100 | 0-100 (Converted from raw score) |
| Functionality Domains | General Functioning | 6 Detailed Life Domains |
| VA Application | Phased Out | Active Used in Mental Health Evaluations |
The WHODAS scoring system numerically codes each response, contributing to a composite score that ranges from 0 (no disability) to 100 (complete disability). The VA then uses this number to help determine your mental health disability rating.
Implementation of WHODAS 2.0 in VA Evaluations
The VA now uses WHODAS 2.0 scoring in Compensation & Pension (C&P) exams for veterans filing claims for conditions like PTSD, anxiety, depression, and other mental disorders; which means that every question will come from the WHODAS 2.0 manual.
The WHODAS scoring will be used to evaluate your mental health condition and how it impacts your life. This will give the VA the proper understanding on how you are able to work, or can you establish friendship or meaningful relationships amongst your peers.
There would be a short and long version of the evaluation, both you can receive depending on the severity of your conditions.
- 12-item version – commonly used for quicker evaluations
- 36-item version – more comprehensive, often used in complex cases
Understanding how to answer these questions can influence your final rating. You just have to make sure that you answer them clearly and with all honesty. You can acquire the services of educational VA claim consulting, such as Just4Veterans to review your condition ahead of time.
Preparing for a WHODAS 2.0 Assessment
Here’s how to get ready for your WHODAS 2.0 evaluation:
- Be honest but specific. Don’t downplay or exaggerate your condition.
- Document your limitations. Keep a journal that details how your condition affects you daily.
- Review the domains. Familiarize yourself with the six core areas WHODAS measures.
- Consider medical opinions. A supporting letter from a therapist or psychiatrist that references WHODAS domains can strengthen your case.
- Consult professionals. Services like Just4Veterans offer VA claim consulting to help you understand how your symptoms align with the scoring system.
Remember, you’re not just being evaluated for a diagnosis—but for how that diagnosis limits your ability to live a full, independent life.
Exploring Options for Appeal or Reassessment if Necessary
The transition from GAF to WHODAS 2.0 is more than just a procedural update—it’s a shift toward a more objective and holistic view of your mental health. If you’re filing or appealing a VA claim for PTSD, depression, or other mental conditions, understanding how WHODAS scoring works can give you a strategic advantage.
