The Importance of a Holistic Approach in ADHD and Autism Diagnosis

Why Traditional Methods Fall Short

For years, ADHD and autism assessments relied primarily on standardized tests and symptom checklists. While these tools can be useful, they often miss the full complexity of neurodivergent individuals. This is especially true for those who mask, internalise their traits, have above-average IQs, or belong to minority backgrounds. These groups are at a higher risk of being misdiagnosed or overlooked.

A holistic approach to ADHD and autism assessments recognises that neurodivergence varies from person to person. It involves looking beyond strict diagnostic criteria to understand how individuals perceive the world and navigate daily challenges. This approach highlights the importance of their unique experiences.

Limitations of Standardised Tests

Traditional assessment methods depend too much on observable behaviours and symptom criteria. These were largely developed based on stereotypical male childhood presentations of ADHD and autism. Consequently, this poses a significant issue for individuals who don't fit this model, such as:

• Women and AFAB individuals, who may adopt strategies to mask their difficulties.

• Individuals with high intelligence, who often create coping mechanisms to hide their challenges.

• People from culturally diverse backgrounds, where communication styles and social norms influence how symptoms are perceived and reported.

  
  

When clinicians focus only on checklists and visible behaviours, they run the risk of failing to capture the internal experiences of Autistic and ADHD individuals, particularly those who have learned to suppress traits to fit into a neurotypical world.

The Shift to a Holistic Assessment Philosophy

Adopting a holistic approach in ADHD and autism diagnostic assessments recognises that every person has a unique neurocognitive profile. Instead of pushing clients into predetermined diagnostic categories, clinicians should embrace an inquisitive, contextual, and affirming perspective. This involves considering:

• The individual’s lived experiences beyond outwardly observable traits.

• The effects of social conditioning and minority stress on their presentation.

• Their distinct strengths and challenges, rather than focusing solely on deficits.

  
  

An effective question for clinicians is: “How does this individual navigate the world and experience these traits?” This fosters a deeper understanding of the person's reality.

Key Considerations in a Holistic Approach

1. Understanding the Influence of Masking

Masking serves as a survival strategy that allows neurodivergent individuals to mimic neurotypical behaviour. Many clients, especially autistic women and late-diagnosed adults, report facing significant burnout, anxiety, and identity confusion due to prolonged masking.

A holistic assessment must:

• Create a safe environment where clients can remove their masks.

• Explore their experiences in various settings; how they behave in one environment may differ from how they feel in another.

• Acknowledge that the lack of obvious traits doesn't mean they aren’t struggling.

  
  

2. Recognising Internalised Traits

Many Autistic and ADHD individuals do not exhibit the outward behaviors typically associated with these diagnoses. Instead, they may face:

• Severe mental exhaustion from continuous self-monitoring.

• Chronic anxiety or depression due to unmet needs.

• A strong desire for routine and predictability, often without showing distress outwardly.

  
  

Clinicians need to delve beyond visible behaviors. They should consider how the individual experiences emotions, sensory input, and executive functioning challenges internally.

3. Considering IQ and Coping Strategies

Individuals with above-average intelligence may develop effective workarounds, allowing them to excel academically or professionally. Yet, they often struggle with daily tasks, emotional regulation, and social interactions. These individuals may be dismissed because they appear "too successful" to be Autistic or have ADHD.

A holistic approach should:

• Assess various domains of adaptive functioning rather than just academic or career success.

• Evaluate the mental and emotional costs of maintaining a façade of competence.

• Recognise that intelligence does not lessen the impact of disability.

  
  

4. Addressing Higher Missed Diagnoses Among Minority Groups

Research indicates that racial, ethnic, and culturally diverse groups are less likely to receive ADHD or autism diagnoses, despite experiencing comparable disabilities to their white peers. Cultural stigma, systemic bias, and varied communication styles contribute to this gap.

A holistic, culturally responsive assessment should:

• Consider cultural differences in behaviour and expectations.

• Acknowledge systemic barriers to diagnosis and adapt assessment strategies to ensure you are providing culturally-informed and affirming practices.

• Implement trauma-informed, affirming approaches that take intersecting challenges into account.

  
  

Importance of Training for Psychologists

For psychologists to deliver accurate ADHD and autism diagnoses, it's essential to move beyond rigid diagnostic frameworks. ADHD and autism assessment training should equip professionals with skills to:

• Identify masked and internalised presentations.

• Conduct contextual, strengths-based assessments.

• Understand the disability and functional impacts individuals face because of their neurotype.

• Recognise the influence of social, cultural, and gender factors on diagnosis.

• Engage in neurodiversity-affirming, client-centred practice.

  
  

The Call for Holistic Understanding

A holistic approach to ADHD and autism assessment emphasises understanding the individual, rather than merely ticking off diagnostic boxes. By focusing on qualitative data, personal stories, and an intersectional lens, clinicians can achieve more accurate and meaningful diagnoses.
