DSM-IV and DSM-5 in Terms of PTSD and Its Effects on VA Disability Ratings

Effective August 4, 2014, the amendment to 38 CFR 4.125 states that a mental disorder diagnosis must conform to the standards set in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Before that date, the regulation required diagnoses to conform to the DSM-IV.

Introduction

Post-Traumatic Stress Disorder (PTSD) has undergone significant changes in its diagnostic criteria with the transition from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) to the Fifth Edition (DSM-5). These changes have profound implications for veterans seeking disability ratings from the Department of Veterans Affairs (VA). This article explores the critical differences between DSM-IV and DSM-5 in diagnosing PTSD, the rationale behind these changes, and their impact on VA disability ratings.

Evolution of PTSD Diagnostic Criteria

DSM-IV Criteria

Under DSM-IV, the classification of PTSD was under Anxiety Disorders, and the following criteria were required for diagnosis.

- Criterion A: Exposure to a traumatic event involving actual or threatened death, serious injury, or a threat to physical integrity, with a response involving intense fear, helplessness, or horror.

- Criterion B: Persistent re-experiencing of the traumatic event (e.g., flashbacks, nightmares).

- Criterion C: Persistent avoidance of stimuli associated with the Trauma and numbing of general responsiveness.

- Criterion D: Persistent symptoms of increased arousal (e.g., hypervigilance, exaggerated startle response).

- Criterion E: The duration of symptoms is more than one month.

- Criterion F: Significant distress or impairment in social, occupational, or other important areas of functioning.

DSM-5 Criteria

The DSM-5 introduced several fundamental changes:

Reclassification moved PTSD from Anxiety Disorders to a new category called Trauma- and Stressor-Related Disorders 2 5.

- Criterion A: Expanded to include direct exposure, witnessing, learning about Trauma to a close relative or friend, and repeated or extreme exposure to aversive details of the traumatic event (e.g., first responders) 5.

- Criterion B: Re-experiencing symptoms remained similar but with refined descriptions.

- Criterion C: Avoidance symptoms were separated from numbing symptoms, now categorized under Criterion D.

- Criterion D: New category for negative alterations in cognitions and mood, including symptoms like persistent negative beliefs and feelings of detachment 1 7.

- Criterion E: Alterations in arousal and reactivity, including irritability, reckless behavior, and sleep disturbances.

- Criterion F: The duration of symptoms is more than one month.

- Criterion G: Significant distress or impairment in social, occupational, or other important areas of functioning.

- Criterion H: Symptoms not attributable to substance use or other medical conditions.

Rationale for Changes

The changes from DSM-IV to DSM-5 were driven by extensive research and clinical input aimed at improving diagnostic accuracy and reflecting a better understanding of PTSD. The reclassification into Trauma and Stressor Related Disorders acknowledges PTSD arises specifically from exposure to traumatic events, differentiating it from other anxiety disorders 1 5.

Impact on VA Disability Ratings

Diagnostic Criteria

The VA adopted DSM-5 criteria in August 2014, so they evaluate all PTSD disability claims received or pending review on or after this date using the new criteria 2.

This transition has several implications:

- Symptom Clusters: The separation of avoidance and numbing symptoms into distinct clusters (Criteria C and D) allows for more precise identification and documentation of PTSD symptoms 7.

- Expanded Criterion A: The broadened definition of traumatic exposure under Criterion A may lead to more veterans qualifying for a PTSD diagnosis, as it includes indirect exposure to trauma 9.

- Negative Cognitions and Mood: The inclusion of negative alterations in cognitions and mood (Criterion D) provides a more comprehensive understanding of the psychological impact of Trauma, potentially leading to higher disability ratings for veterans with severe symptoms. 1 5.

Evaluation and Rating

The VA rates PTSD on a scale from 0% to 100% based on the severity of symptoms and their impact on daily life, work efficiency, and social functioning 3.

The DSM-5 criteria influence this rating process in several ways:

- Detailed Symptom Documentation: The refined criteria require more detailed documentation of symptoms, which can aid in accurately assessing the severity of PTSD and determining the appropriate disability rating 6.

- Consistency in Evaluation: The standardized criteria help ensure consistency in evaluations across different VA examiners and facilities, potentially reducing variability in disability ratings 6.

- Potential for Higher Ratings: The new symptom clusters and expanded definitions may lead to higher ratings for veterans with complex PTSD presentations, as the criteria capture a broader range of symptoms and their effects 5.

Challenges and Considerations

While the DSM-5 criteria offer several advantages, there are also challenges and considerations for veterans and clinicians:

- Transition Period: The transition from DSM-IV to DSM-5 may have led to initial evaluation inconsistencies as clinicians adapted to the new criteria 5.

- Documentation Requirements: The detailed documentation required by DSM-5 can be time-consuming for clinicians and may require additional training and resources 6.

- Impact on Prevalence: Some studies suggest that the prevalence of PTSD diagnoses may decrease slightly under DSM-5 because of the more stringent criteria, mainly the exclusion of sudden unexpected death of a loved one from Criterion A 9.

Conclusion

The transition from DSM-IV to DSM-5 brought significant changes to the diagnostic criteria for PTSD, reflecting advancements in our understanding of the disorder. These changes have important implications for veterans seeking VA disability ratings. The reclassification of PTSD expanded definitions of traumatic exposure and refined symptom clusters provide a more comprehensive framework for diagnosing and evaluating PTSD. While the new criteria offer several benefits, including more detailed documentation and consistency in evaluations, they also present challenges regarding adaptation and documentation requirements. Overall, the DSM-5 criteria for PTSD are a step forward in accurately diagnosing and assessing the impact of Trauma on veterans. By understanding these changes and their implications, veterans and clinicians can better navigate the VA disability rating process and ensure that veterans receive the support and compensation they deserve.
