Understanding Self-Injurious Behaviors in Autistic Children: Shedding Light on a Complex Issue

Self-injurious behaviors (SIBs) can be challenging for individuals with autism spectrum disorder (ASD) and their caregivers. It’s important to approach SIBs with empathy, understanding, and a comprehensive support plan. Here are some strategies that can be helpful in managing and addressing self-injurious behaviors in individuals with autism:

Understanding Self-Injurious Behaviors

Self-injurious behaviors often serve a specific purpose for the individual engaging in them. It could be a means of communication, an attempt to gain attention or sensory stimulation, or a response to frustration or anxiety. Identifying the underlying cause or trigger of the behavior can guide intervention strategies. It is important to seek professional guidance when it comes to working with individuals who engage in SIB. Consulting with professionals, like Board Certified Behavior Analysts (BCBAs), who specialize in ASD and behavior management, can provide valuable insights and tailored strategies for addressing self-injury. We will dive deeper into what assessments are used to understand the function of SIB, but below are some common and potential reasons:

Sensory sensitivities

Sensory sensitivities are a prominent feature of autism spectrum disorder (ASD) and can significantly impact the daily lives of autistic children and may be a cause of SIB. These sensitivities involve atypical responses to sensory stimuli, such as sound, touch, taste, smell, and visual input. Understanding and addressing sensory sensitivities in autistic children is crucial for promoting their well-being and enabling them to thrive.

The Spectrum of Sensory Sensitivities – Sensory sensitivities in autistic children exist on a wide spectrum, with each individual having unique preferences and aversions. The two main categories of sensory sensitivities are:

• Hypersensitivity (over-responsivity): Autistic children with hypersensitivity experience heightened responses to sensory stimuli. They may find certain sounds painfully loud, textures unbearable, or bright lights overwhelming. Even everyday sensory experiences, like clothing tags or background noise, can trigger discomfort or distress.
• Hyposensitivity (under-responsivity): Conversely, some autistic children exhibit hyposensitivity, characterized by diminished responses to sensory input. They may seek out intense sensory experiences, such as spinning or repetitive movements, to compensate for a lack of sensory input. They might also have a higher pain tolerance or difficulty recognizing body signals, such as hunger or temperature.

Impact of Sensory Sensitivities – Sensory sensitivities can significantly impact autistic children’s lives, influencing their behavior, emotions, and overall well-being:

• Emotional regulation: Sensory overload can lead to emotional dysregulation, resulting in anxiety, frustration, meltdowns, or withdrawal. Understanding and managing sensory triggers can help regulate emotions more effectively.
• Social interactions: Sensory sensitivities can affect social interactions, as children may struggle with sensory aspects of communication, such as maintaining eye contact or tolerating physical touch. This can lead to social isolation or misinterpretation of social cues.
• Daily routines and activities: Sensory sensitivities can disrupt everyday routines and activities. For example, sensitivity to certain food textures might limit dietary choices, or aversion to crowded places might affect participation in community events.

Communication Difficulties

Communication is an essential aspect of human interaction, allowing us to express our thoughts, needs, and emotions. For autistic children, communication difficulties represent a core challenge associated with autism spectrum disorder (ASD). Understanding these difficulties and implementing effective strategies to support communication development is crucial for promoting their social and emotional well-being.

Nature of Communication Difficulties – Communication difficulties in autistic children encompass a broad range of challenges that can vary from individual to individual. Some common characteristics include:

• Delayed language development: Many autistic children experience delays in acquiring speech and language skills compared to their neurotypical peers. They may have limited vocabulary, difficulty with grammar and syntax, or struggle with articulation.

• Nonverbal communication: Autistic children may face challenges with nonverbal communication cues, such as maintaining eye contact, understanding gestures, or interpreting facial expressions. This can impact their ability to engage in reciprocal social interactions.

• Social communication deficits: Difficulties in social communication, including understanding social norms, initiating and sustaining conversations, and using appropriate turn-taking, are common among autistic children. They may have trouble adapting their communication style to different contexts or understanding the perspective of others.

• Echolalia: Echolalia, the repetition of words or phrases, is often observed in autistic children. It can serve as a way to communicate, practice language, or self-regulate. However, echolalia may not always convey meaningful communication in a given context.

Impact of Communication Difficulties – Communication difficulties can significantly impact various aspects of autistic children’s lives:

• Social interactions: Challenges in communication can hinder the development of social relationships and result in social isolation. Difficulty understanding and expressing emotions may lead to misunderstandings and difficulty forming connections with peers.

• Emotional regulation: Communication difficulties can make it challenging for autistic children to express their needs, desires, and emotions effectively. This can contribute to frustration, anxiety, and emotional dysregulation.

• Academic performance: Communication difficulties may affect academic progress, as language skills are essential for comprehension, reading, and written expression. Difficulties in understanding instructions or expressing thoughts can impact learning outcomes.

• Behavior and self-expression: When communication is limited, autistic children may resort to alternative ways of expressing their needs or frustrations, which can manifest as challenging behaviors. Frustration from communication breakdowns may lead to meltdowns or withdrawal.

Anxiety and Stress

Anxiety and stress are common experiences for many individuals, and autistic children are no exception. Autism spectrum disorder (ASD) often coexists with heightened levels of anxiety and stress, which can significantly impact a child’s well-being and daily functioning. Understanding the causes, manifestations, and effective strategies for supporting autistic children with anxiety and stress is crucial for promoting their mental health and overall quality of life.

Causes and Manifestations of Anxiety and Stress – Several factors contribute to the development of anxiety and stress in autistic children:

• Difficulty with change and transitions: Autistic children often thrive on predictability and routine. Changes in routine, unexpected events, or transitions can create uncertainty and anxiety, leading to increased stress levels.

• Social challenges: Social interactions can be a significant source of anxiety and stress for autistic children. Difficulties in understanding social cues, maintaining friendships, or feeling excluded can contribute to heightened anxiety in social situations.

• Communication difficulties: Challenges in communication, such as expressing needs or understanding instructions, can lead to frustration and anxiety. Difficulties in effectively conveying thoughts and emotions may exacerbate stress levels.

• Overstimulation and information processing: Autistic individuals may struggle with filtering and processing overwhelming amounts of information. This cognitive overload can contribute to anxiety and stress.

What is the Function of the Behavior? How we assess: 

Conducting an Functional Behavior Assessment can help determine the antecedents (triggers), consequences, and functions of the self-injurious behavior. This assessment helps identify patterns and provides a foundation for developing an effective behavior support plan using direct and indirect assessment methods. Once a FBA is completed, then it is time to develop a behavior support plan. A behavior support plan outlines strategies to address self-injury. It may include positive reinforcement for alternative behaviors, modifying the environment to reduce triggers, teaching coping skills, and implementing appropriate consequences. The plan should be individualized and developed collaboratively with professionals, caregivers, and the individual with ASD.

Replacing SIBs with Appropriate Behaviors:

Many individuals with ASD engage in self-injury due to communication challenges. Teaching alternative communication methods, such as using visual supports, augmentative and alternative communication (AAC) systems, or sign language, can help individuals express their needs and reduce frustration. Sensory issues often contribute to self-injurious behaviors as well. Implementing sensory regulation strategies, such as providing sensory breaks, incorporating sensory activities, or using sensory tools like fidget toys, weighted blankets, or noise-canceling headphones, can help individuals regulate their sensory needs and reduce the likelihood of self-injury. It can also be beneficial to encourage those who engage in SIB to seek social interaction and find a supportive social network that can contribute to improved emotional well-being. In conjunction with other evidence based strategies, social stories, which are personalized narratives that explain social situations and appropriate behaviors, can help individuals with autism better understand and cope with challenging situations.

Collaboration & Effectiveness:

Effective intervention that targets SIB requires collaboration among caregivers, educators, therapists, and medical professionals involved in the individual’s care. Regular communication, sharing progress and data, and adjusting strategies based on the individual’s needs are essential for success. It is crucial to keep a record of the self-injurious behaviors, interventions used, and their effectiveness. Tracking progress can help identify patterns, make adjustments to strategies, and determine the effectiveness of interventions over time. A BCBA will regularly analyze data to ensure that those most effective, pragmatic interventions are being utilized.

Self-injurious behaviors in autistic children are complex and multifaceted. Understanding the underlying factors and triggers can assist in developing effective strategies to support and manage these behaviors. By employing a holistic approach that addresses sensory sensitivities, communication difficulties, and emotional well-being, it is possible to improve the quality of life for autistic children and provide them with alternative ways to cope with challenges. With patience, empathy, and the right support, autistic individuals can thrive and reach their full potential.
