Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by persistent challenges in social interaction, communication, and restricted or repetitive patterns of behavior. The current diagnostic manual categorizes individuals based on the support they require, using three severity levels. This article focuses specifically on understanding the traits and support needs associated with Level 2 autism.
Defining Level 2 Autism
Level 2 autism is formally defined in the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) as “Requiring Substantial Support.” This designation indicates that difficulties in social communication and restricted, repetitive behaviors are noticeable to the casual observer and significantly impair daily functioning. Impairments are evident even when supports are in place, distinguishing Level 2 from Level 1 (less support) and Level 3 (“Very Substantial Support”).
Individuals at this level experience challenges that affect their ability to function across various aspects of daily life, requiring consistent, ongoing assistance. The severity level is determined by assessing the degree of impairment across both the social communication and the restricted/repetitive behavior domains.
Social Communication Impairments
Level 2 autism is characterized by marked deficits in both verbal and nonverbal social communication skills. These social impairments are apparent even when external supports are available. Individuals may speak using simple sentences or short phrases, but they often struggle to sustain a back-and-forth conversation.
Communication may be limited to specific, narrow interests, making it difficult to engage in typical reciprocal social exchanges. They often show reduced responses to social overtures and have difficulty initiating social interactions. Nonverbal communication is also noticeably affected, often presenting as limited eye contact, a flat facial affect, or difficulty reading social cues like body language and tone of voice.
These challenges significantly impact the ability to build and maintain relationships, often leading to misunderstandings or isolation. They may struggle with nuanced social concepts, such as interpreting sarcasm or humor, or adjusting their communication style for different listeners. The combination of limited verbal skills and difficulty with nonverbal signals results in noticeable social awkwardness that requires consistent intervention.
Patterns of Restricted and Repetitive Behaviors
The non-social criteria for Level 2 autism involve restricted, repetitive behaviors (RRBs) that are frequent and obvious enough to be noticed by the casual observer. These behaviors significantly interfere with the person’s functioning across multiple environments. Repetitive motor movements, such as hand-flapping, body rocking, or spinning, may be present for self-soothing or sensory regulation.
Individuals at this level display inflexibility of behavior and difficulty coping with change. When routines are interrupted or expectations change, the person may experience distress or frustration, which can manifest as anxiety or behavioral outbursts. They may have intense, fixated interests that are abnormal in their focus or intensity, making redirection difficult.
Insistence on sameness and adherence to ritualized patterns can make transitioning between activities challenging. Sensory issues are also common, involving heightened or reduced responses to stimuli like bright lights, loud noises, or certain textures. These behavioral patterns require substantial intervention to minimize their impact on daily life.
Necessary Support and Intervention Strategies
The substantial support required for Level 2 autism necessitates a comprehensive and intensive intervention approach. Applied Behavior Analysis (ABA) therapy is a widely used, evidence-based intervention that focuses on developing new skills and reducing challenging behaviors through positive reinforcement and structured teaching methods. This therapy is often delivered with high intensity to address the moderate level of impairment.
Speech therapy is a component, specifically targeting deficits in both expressive and receptive communication. Therapists work to improve functional communication, which may involve developing verbal skills, enhancing vocabulary, or utilizing augmentative and alternative communication (AAC) systems. Visual supports, such as visual schedules and the Picture Exchange Communication System (PECS), are often introduced to help with comprehension and facilitate initiation of requests.
Occupational therapy (OT) addresses sensory processing challenges and teaches skills necessary for daily living. OT helps individuals develop self-care abilities like dressing and grooming, and provides strategies to manage sensory input and improve self-regulation. In educational settings, a structured environment, such as a specialized classroom or resource room, is needed to provide the adult supervision and prompting required for skill acquisition. Teaching functional skills and coping mechanisms for transitions and routine changes is a continuous focus across all support environments.
