Given a 6-year-old boy with autism spectrum disorder and ADI‑R (Autism Diagnostic Interview‑Revised) scores of 11 for social interaction, 9 for communication, and 8 for restricted/repetitive behaviors, should he be assigned Level 2 support for the social‑communication and restricted‑repetitive behavior domains?

DSM-5 Level 2 Support Assignment: Clinical Disagreement Analysis

Direct Recommendation

Based on this child's clinical presentation, I agree with the Level 2 support designation for both social communication and restricted/repetitive behaviors. The ADI-R scores, developmental history showing regression at 12 months with first words not emerging until age 5, and current functional limitations requiring intensive ABA therapy all support this severity level 1, 2.

Rationale for Level 2 Support in Social Communication

Marked Deficits Present

  • This child demonstrates "marked deficits in verbal and nonverbal social communication skills" consistent with Level 2 criteria 1. His first words emerged at age 5 (compared to typical 12-18 months), he currently produces only 2-3 word phrases with prompting, and relies heavily on echolalia rather than spontaneous communication 3, 2.

  • Limited initiation of social interactions is clearly documented 1. He does not spontaneously engage in conversation, requires prompting for most communication, and his social overtures lack coordination of gaze, gesture, and vocalization—instead grabbing adults and leading them to objects 3.

  • Reduced or absent response to social overtures from others is evident 1, 2. He walks away when other children approach him, demonstrates inconsistent eye contact occurring mainly when he wants something, and does not automatically pay attention when spoken to without extra prompting 3.

Functional Impact Supports Level 2

  • The family reports significant functional impairment requiring careful planning and resulting in social isolation 1. They cannot engage in typical activities like dining out or attending events, and experience helplessness during his meltdowns when he cannot communicate his needs 3.

  • His ADI-R Communication score of 9 (cutoff 8) and Social Interaction score of 11 (cutoff 10) both exceed diagnostic thresholds 4, 5, indicating clinically significant impairment beyond what would warrant Level 1 support.

Rationale for Level 2 Support in Restricted/Repetitive Behaviors

Observable and Interfering Behaviors

  • His restricted interests and repetitive behaviors "appear frequently enough to be obvious to the casual observer and interfere with functioning in a variety of contexts"—the exact DSM-5 language for Level 2 1.

  • His preoccupation with rocks is intrusive and disruptive, preventing normal activities like hiking 3. This goes beyond the Level 1 criterion of "interfering with functioning in one or more contexts" to clearly affecting multiple domains.

  • His ADI-R Restricted/Repetitive Behaviors score of 8 (cutoff 3) substantially exceeds the diagnostic threshold 4, 6, indicating severity beyond mild impairment.

Sensory and Behavioral Manifestations

  • Significant sensory sensitivities requiring noise-canceling headphones and showing distress with unfamiliar sounds demonstrate marked impairment 3, 1, 2. His hypo-reactivity to pain (ignoring discomfort until severe, multiple bruises from self-injury) and hyper-reactivity to auditory stimuli occur frequently 3, 2.

  • Self-injurious behaviors during meltdowns causing bruising represent a safety concern 3, elevating the clinical significance beyond Level 1 support needs.

Why Not Level 1?

Level 1 would be inappropriate given the severity of functional impairment 1. Level 1 requires that "without supports in place, deficits in social communication cause noticeable impairments" but the child can function with minimal support. This child:

  • Required no verbal communication until age 5 3, 2
  • Currently needs intensive ABA therapy described as "life-changing" 3
  • Cannot participate in typical family activities without significant accommodation 1
  • Demonstrates parallel play only, with minimal interactive engagement 3, 7

Why Not Level 3?

Level 3 would be excessive given his emerging skills and response to intervention 1. Level 3 requires "severe deficits" causing "severe impairments in functioning" with "very limited initiation" and "minimal response to social overtures." This child:

  • Shows social smiling and can be redirected through positive engagement 3, 7
  • Demonstrates interest in other children and will approach peers 3, 7
  • Has made significant gains with ABA therapy 3
  • Uses an AAC device effectively 3
  • Shows emerging ability to label emotions and objects 3, 7

Critical Considerations for Level Assignment

ADI-R Scores Support Level 2

  • Research demonstrates that ADI-R domain scores correlate with functional impairment in verbal children 8. His scores of 11 (Social), 9 (Communication), and 8 (Restricted/Repetitive) all exceed cutoffs but are not in the extreme range that would suggest Level 3 4, 6.

  • The ADI-R has excellent interrater reliability (ICC 0.91-1.00) in clinical settings 4, supporting confidence in these scores as valid indicators of symptom severity.

Developmental Trajectory Matters

  • His history of regression at 12 months followed by extremely delayed language emergence (age 5) indicates substantial early impairment 3, 2. Early markers including failure to respond to name, lack of pointing, and absence of conventional gestures at 20-42 months are highly specific for ASD requiring more than minimal support 1, 2.

  • However, his recent progress with intensive intervention suggests he is not at the severe end of the spectrum 3, 6. Studies show ADI-R scores in Social and Communication domains can decrease over time with intervention, while Restricted/Repetitive scores remain more stable 6.

Common Pitfalls to Avoid

  • Do not underestimate severity based on emerging skills alone 1, 7. The American Academy of Child and Adolescent Psychiatry emphasizes that children with ASD may show progress in some areas while still requiring substantial support 7.

  • Do not assign Level 1 simply because the child has some verbal language 1, 2. The quality and functional use of communication matters more than vocabulary count 7.

  • Do not assign Level 3 based solely on early developmental history if current functioning shows response to intervention 6, 5. Level assignment should reflect current support needs, not just historical severity 1.

The Level 2 designation accurately captures this child's current need for "substantial support" while acknowledging his capacity for growth with intensive intervention 1, 5.
