Individuals with autism exhibit mild symptoms that may not be immediately apparent. Moreover, individuals may exhibit severe repetitive behaviours and restricted interests, which can interfere with daily activities and relationships. These behaviours may pose safety concerns or lead to self-injury, necessitating intensive behaviour management strategies and supervision. Understanding the three levels of autism is essential for recognising the diverse presentations of the condition and providing targeted support and interventions.

What are the three levels of autism?

The three levels of autism, as defined in the DSM-5, are Level 1 (requiring support), Level 2 (requiring substantial support), and Level 3 (requiring very substantial support).

Understanding the Three Levels of Autism

Each level reflects the varying degrees of severity and the support needed by individuals with ASD. Let’s understand in detail:

Level 1 (requiring support)

Individuals at Level 1 of the autism spectrum require relatively mild support. They may exhibit noticeable impairments in social communication, particularly initiating social interactions and responding to social cues.

Characteristics of Level 1 Autism

Difficulty initiating and maintaining social interactions
Challenges in adapting to changes in routine or environment
Special interests and repetitive behaviours
Verbal communication difficulties, such as understanding non-literal language

Challenges Faced by Individuals at Level 1

Navigating social situations and forming friendships
Coping with unexpected changes in routines
Dealing with sensory sensitivities
Understanding an abstract or non-literal language

Support and Interventions for Level 1 Autism

Social skills training to improve interactions and communication
Cognitive-behavioural therapy to address inflexibility and anxiety
Sensory accommodations to reduce sensory overload
Individualised education plans (IEPs) in educational settings

Level 2 (requiring substantial support)

At Level 2 of the autism spectrum, individuals require more substantial support across various areas of functioning. They exhibit marked impairments in social communication and demonstrate restricted, repetitive behaviours that significantly impact their daily functioning. Individuals at this level often face challenges in adapting to change and may require consistent support to navigate social situations and activities of daily living.

Characteristics of Level 2 Autism

Severe challenges in social communication and interaction
Pronounced inflexibility of behaviour and difficulty coping with change
Highly restricted, fixated interests
Significant difficulty in initiating social interactions

Challenges Faced by Individuals at Level 2

Forming and maintaining relationships
Managing intense fixations and repetitive behaviours
Coping with sensory overload in various environments
Accessing and succeeding in education and employment

Support and Interventions for Level 2 Autism

Structured behavioural interventions to address repetitive behaviours
Individual or group therapy to improve social communication skills
Supported employment programmes and workplace accommodations
Sensory integration therapy to manage sensory sensitivities

Level 3 (requiring very substantial support)

Individuals at Level 3 of the autism spectrum require very substantial support due to the severe impairments in social communication and the extreme inflexibility of their behaviour. Their adaptive functioning is significantly limited, and they may exhibit little interest in social interactions. These individuals often require intensive, hands-on support across all aspects of life, including personal care, safety, and communication.

Characteristics of Level 3 Autism

Severe impairments in verbal and nonverbal communication
Minimal interest in social interactions
Extremely rigid routines and resistance to change
Significant challenges in managing daily living skills

Challenges Faced by Individuals at Level 3

Meeting basic self-care needs
Communicating basic wants and needs
Navigating environments without intense sensory overload
Accessing appropriate education and specialised care

Support and Interventions for Level 3 Autism

Intensive behavioural interventions tailored to individual needs
Specialised communication strategies, such as augmentative and alternative communication (AAC) systems
Adaptive equipment and assistive technology to enhance independence

Conclusion

Comprehending the three levels of autism is essential for fostering understanding, support, and inclusion within society. Understanding each level of autism enables carers, educators, and healthcare professionals to provide targeted support and enhance the quality of life for those on the spectrum.
