ASD Case Study: Adult with Developmental Challenges
This case study examines a 26-year-old male diagnosed with Autism Spectrum Disorder (ASD) Level 2 who experienced increased anxiety and resistance to attending a vocational training center. The paper outlines his background, presenting concerns, personal strengths, and daily living challenges before detailing a holistic, multi-modal intervention plan. Interventions included Applied Behavior Analysis-based behavioral therapy, sensory integration-focused occupational therapy, family counseling, and music therapy. After six months of consistent treatment, the client demonstrated significantly reduced anxiety, renewed participation in vocational programming, and improved social confidence. The case illustrates the value of strength-based, interdisciplinary approaches in supporting adults with developmental disabilities.

What makes this paper effective
- The case study follows a clear, logical structure — moving from background and concerns to strengths, interventions, and outcomes — which makes complex clinical information easy to follow.
- Each intervention is grounded in a named theoretical framework (Applied Behavior Analysis, sensory integration theory), demonstrating awareness of evidence-based practice.
- The paper takes a genuinely strength-based approach, identifying the client's musical ability and family relationships as foundations for intervention design rather than treating them as incidental details.
Key academic technique demonstrated
The paper models interdisciplinary case conceptualization: rather than relying on a single clinical modality, it coordinates behavioral, occupational, relational, and expressive therapeutic approaches under one coherent treatment plan. This integrative structure reflects graduate-level clinical thinking about multi-domain needs in adults with ASD.
Structure breakdown
The paper opens with client demographics and diagnosis, then establishes context through background and presenting concerns. A dedicated strengths-and-challenges section precedes the intervention descriptions, ensuring that assets inform treatment. Four discrete interventions are presented sequentially, followed by a unified outcomes section and a brief reflective conclusion that ties back to the holistic approach theme.
Client Background and Presenting Concerns
The client is a 26-year-old male diagnosed with Autism Spectrum Disorder (ASD), Level 2 (requiring substantial support). He was diagnosed with ASD at the age of 4. His family has been supportive throughout his life and into adulthood. He has two parents, two siblings, and an extended family that continues to support and assist him. He attended a special education school until the age of 18 and, in his mid-20s, began attending a vocational training center for adults with developmental disabilities.
The client's family noticed an increase in his anxiety levels, particularly when changes occurred to an already established routine. They began to observe his resistance to attending his vocational training center, which, though he had been attending without issue for more than a year, was still relatively new to him. His limited verbal communication skills made it difficult to discuss how he felt or what he was experiencing. To express his discomfort, he relied on repetitive behaviors such as hand-flapping and rocking.
Strengths and Challenges
The client has a strong memory for details and can recall dates, times, events, and facts with excellent precision. He has a deep interest in and love for music, and he has learned to play the keyboard with the assistance of a special educator. He also maintains a very close relationship with his younger sister, Emily, whose bond with him is notably strong. She frequently serves as an interpreter, as she understands his non-verbal cues better than anyone else in his life.
At the same time, the client struggles with social interactions due to difficulty understanding social cues. He experiences sensory sensitivities — particularly to loud noises and bright lights — which can heighten his anxiety. He also continues to require assistance with daily living activities, including personal hygiene and meal preparation.
Behavioral and Occupational Therapy Interventions
A behavior therapist was consulted to address the client's increased anxiety and resistance to attending the vocational training center. Drawing on the theory of Applied Behavior Analysis (ABA), the therapist worked on developing a structured routine for the client. This consisted of incorporating visual schedules and social stories to help him understand and anticipate any changes occurring at the training center.
An occupational therapist applied sensory integration theory to address the client's sensory sensitivities. The therapist introduced the use of noise-canceling headphones and light-filtering glasses, both of which helped the client maintain calm while at the vocational training center. These accommodations reduced the environmental triggers that had been contributing to his elevated anxiety.
