The Diagnostic and Statistical Manual of Mental Disorders (DSM) is the primary resource used by healthcare professionals in the United States for diagnosing mental health conditions. Published by the American Psychiatric Association (APA), the DSM has undergone several revisions to reflect the evolving understanding of mental disorders. One significant change was the move from the DSM-IV to the DSM-5, which included the removal of the multi-axial system. While the “5 axis diagnosis” is no longer a feature of the current DSM-5, understanding this historical framework is crucial for context and for those familiar with previous diagnostic methods. This article will explore the 5 Axis Diagnosis Dsm 5, clarifying its role in the DSM-IV and its absence in the DSM-5.
The Multi-Axial System of DSM-IV: A 5 Axis Approach
In the DSM-IV, diagnoses were organized using a multi-axial system, often referred to as the “5 axis diagnosis”. This system was designed to provide a comprehensive and multi-dimensional evaluation of an individual’s mental health. Each of the five axes addressed a different category of information, allowing clinicians to create a more complete picture of the patient’s condition.
The five axes in the DSM-IV were:
- Axis I: Clinical Disorders: This axis encompassed the major clinical syndromes that are typically what we think of as mental health conditions. This included disorders such as depression, anxiety disorders, schizophrenia, and substance use disorders.
- Axis II: Personality Disorders and Mental Retardation: Axis II was reserved for personality disorders and mental retardation (now referred to as intellectual developmental disorder). These conditions were considered to be more chronic and pervasive aspects of an individual’s functioning.
- Axis III: General Medical Conditions: This axis was used to note any current general medical conditions that might be relevant to understanding or treating the individual’s mental disorder. Physical health conditions could significantly impact mental health, and this axis ensured these factors were considered.
- Axis IV: Psychosocial and Environmental Problems: Axis IV highlighted psychosocial and environmental factors contributing to the disorder. This could include issues like problems with primary support groups, occupational difficulties, economic problems, or housing issues.
- Axis V: Global Assessment of Functioning (GAF): Axis V involved a Global Assessment of Functioning (GAF) scale, a numerical rating from 0 to 100 representing the clinician’s judgment of the individual’s overall level of functioning. This score aimed to summarize the person’s psychological, social, and occupational functioning.

The History and Purpose of the 5 Axis System
Introduced in the DSM-III, the multi-axial system was designed to ensure that clinicians considered a broader range of information when diagnosing mental disorders. The intention was to move beyond simply labeling a patient with a psychiatric diagnosis and instead to provide a richer, more nuanced understanding of the individual’s overall situation.
For example, a patient diagnosed with Major Depressive Disorder (Axis I) might also have information recorded on Axis IV, such as “Problems with primary support group,” and an Axis V GAF score reflecting their current functional level. This multi-faceted approach was intended to improve diagnostic accuracy and treatment planning by considering various aspects of a patient’s life and health.
The aim was to create a standardized system that would encourage healthcare professionals to systematically evaluate patients across these five domains. By using the 5 axis system, clinicians could organize complex diagnostic information efficiently and ensure that no critical area was overlooked.
Why the 5 Axis Diagnosis Was Discontinued in DSM-5
Despite its good intentions, the multi-axial system faced criticism and ultimately was removed with the publication of the DSM-5 in 2013. The APA determined that the system lacked a strong scientific basis and, in practice, it sometimes led to confusion and did not consistently improve clinical utility.
Key reasons for discontinuing the 5 axis diagnosis included:
- Artificial Distinctions: Many clinicians found the separation between Axis I and Axis II disorders to be somewhat arbitrary. The distinction was not always clear-cut, and some conditions could arguably fit into either category.
- Conceptual Confusion: There was ongoing debate and confusion about the difference between “mental disorders” (Axis I) and “personality disorders” (Axis II). This distinction didn’t always reflect the clinical reality of overlapping symptoms and conditions.
- Limited Utility of GAF (Axis V): The Global Assessment of Functioning (GAF) scale, while intended to provide a snapshot of overall functioning, was criticized for its subjectivity and lack of sensitivity to change. Furthermore, it didn’t adequately capture crucial aspects like suicide risk or disability levels.
- Integration with ICD: The move towards a non-axial system also aligned the DSM more closely with the International Classification of Diseases (ICD), which does not use a multi-axial system. This harmonization was seen as beneficial for international communication and research.
The DSM-5 and the Shift to a Non-Axial System
The DSM-5 transitioned to a non-axial diagnostic system. This means that the separate axes were eliminated, and instead, the DSM-5 combines what were Axes I, II, and III into the primary diagnostic listing. Information that would have been coded on Axis IV and Axis V is now incorporated using separate notations and dimensional assessments.
In the DSM-5, clinicians are encouraged to consider and document psychosocial and contextual factors (previously Axis IV) and to assess functional impairment, but these are not structured into distinct axes. The focus shifted towards a more integrated approach, where all relevant diagnostic information is considered without being artificially separated into axes.
For instance, instead of listing diagnoses across five axes, a DSM-5 diagnosis might look like:
- Major Depressive Disorder, recurrent episode, severe
- Posttraumatic Stress Disorder
- Obesity (as a relevant medical condition)
- Job loss and marital problems (psychosocial stressors)
- Assessment of functional impairment using standardized scales (replacing GAF).
This approach aims to streamline the diagnostic process and encourage clinicians to consider the full spectrum of factors influencing a patient’s mental health without being constrained by the artificial divisions of the 5 axis system.
Changes and Continuities from DSM-IV to DSM-5
While the 5 axis system is no longer part of the DSM-5, many of the concepts it represented remain important in clinical practice. The DSM-5 still emphasizes the importance of considering:
- Clinical Disorders: The core mental health conditions remain the central focus of diagnosis.
- Personality and Developmental Disorders: These are still recognized as significant patterns of maladaptive functioning. Intellectual Disability is now termed Intellectual Developmental Disorder in DSM-5-TR, with “Intellectual Disability” in parentheses for continued use.
- Medical Conditions: The influence of general medical conditions on mental health is still a critical consideration.
- Psychosocial and Environmental Factors: These contextual elements are considered crucial in understanding and treating mental disorders, even without Axis IV.
- Functional Impairment: Assessing the level of functional impairment remains a key component of diagnosis and treatment planning, although the GAF scale is no longer used. DSM-5 encourages the use of more specific and reliable measures of functioning.
The DSM-5-TR, the text revision of the DSM-5, further refined diagnostic criteria and incorporated updates based on new research and clinical experience. It also includes specifiers for suicidal behavior and non-suicidal self-injury, addressing some of the limitations previously associated with the GAF scale in capturing risk.
Conclusion: The Legacy of the 5 Axis Diagnosis in DSM-5 and Beyond
While the term “5 axis diagnosis dsm 5” is technically inaccurate because the DSM-5 eliminated the multi-axial system, understanding the historical context of the 5 axis system is valuable. It reflects a period in psychiatric diagnosis where there was a strong emphasis on multi-dimensional assessment.
The shift away from the 5 axis system in DSM-5 represents an evolution in the field, moving towards a more integrated and scientifically grounded approach to diagnosis. Today’s diagnostic practices, informed by the DSM-5 and DSM-5-TR, continue to prioritize a comprehensive understanding of the individual, considering clinical disorders, related medical conditions, psychosocial factors, and functional impairment, albeit without the formal structure of the five axes. For professionals familiar with the DSM-IV, understanding the rationale behind this change is essential for navigating the current diagnostic landscape and appreciating the ongoing evolution of psychiatric classification.
