Can CATI be used to measure autistic inertia

Can CATI be used to measure Autistic Inertia. 

Autistic inertia refers to the challenges autistics may face in initiating, switching, or stopping activities, which can significantly impact various aspects of their lives, from daily routines to employment and social interactions. It manifests in numerous ways, including difficulties with time management, adjusting to changes, motivation, and focusing on tasks. Support strategiesinclude providing structure, teaching time management, organizing activities around energy levels, using visual reminders, establishing routines, breaking tasks down into manageable steps, and offering prompts or assistance with task initiation. [More on autistic inertia here].

While there are no current scales to measure autistic inertia, we could perhaps use one of the measures like CATI (Comprehensive Autistic Trait Inventory) [post on CATI] which covers a broad range of autistic traits, and has subscales may indirectly relate to behaviors and experiences that could be associated with autistic inertia; specifically - social interactions (SOC), communication (COM), social camouflage (CAM), repetitive behaviors (REP), cognitive rigidity (RIG), and sensory sensitivity (SEN).

• Cognitive Rigidity (RIG) could relate to difficulties with changing activities or adapting to new tasks, as it may measure aspects of flexibility in thinking and behavior.
• Repetitive Behaviors (REP) might also have connections to autistic inertia, given that a preference for sameness and routine or repetitive actions could impact the ability to start or stop activities.
• Sensory Sensitivity (SEN) could influence autistic inertia by affecting how sensory inputs are processed, potentially making transitions between activities more challenging.
• Social Interactions (SOC): Difficulties in understanding and engaging in social interactions could exacerbate feelings of inertia by increasing anxiety or reluctance to transition into social activities or contexts, impacting the ability to initiate or change social engagements.
• Communication (COM): Challenges with verbal and non-verbal communication may contribute to autistic inertia by making the prospect of initiating or adapting to communicative tasks more daunting, leading to delays or avoidance of these activities.
• Social Camouflage (CAM): The effort required to mask autistic traits in social situations could lead to increased inertia, as the mental and emotional resources expended on camouflaging may reduce the capacity to engage with new tasks or changes.

While these subscales can provide insights into traits that might influence or correlate with autistic inertia, it's important to note that autistic inertia as a specific construct might require more targeted assessment tools or approaches to fully understand and measure its impact on autistics. The CATI provides a broad overview of autistic traits within the general population and is not designed to diagnose autism or directly measure autistic inertia. 

Comparing the ABC and CATI Autism Measures

Autism Assessments & Measures 

The Aberrant Behavior Checklist (ABC) and the Comprehensive Autistic Trait Inventory (CATI) are both tools used to assess behaviors and traits associated with autism, but they differ in their specific focus, structure, and use cases. Here’s a comparison to highlight the differences between the two:

Aberrant Behavior Checklist (ABC)

Purpose: Designed to assess the presence and severity of problem behaviors in individuals with developmental disabilities, including autism.

Structure: Consists of 58 items divided into five subscales:

• 1. Irritability
  2. Lethargy/Social Withdrawal
  3. Stereotypic Behavior
  4. Hyperactivity/Noncompliance
  5. Inappropriate Speech

Administration:

• Completed by caregivers, teachers, or clinicians who are familiar with the individual's behavior.
• Uses a Likert scale (0-3) to rate the severity of each behavior.

Focus:

• Measures the severity and frequency of specific problem behaviors.
• Used to track changes over time and assess treatment effectiveness.

Advantages:

• Provides detailed information about specific behavioral issues.
• Useful for treatment planning and monitoring progress.

Limitations:

• Subjective responses from raters.
• Does not provide a comprehensive assessment of autism traits.

Comprehensive Autistic Trait Inventory (CATI)

Purpose: Designed to provide a detailed assessment of the range of autistic traits across various domains, specifically for research and clinical purposes.

Structure: The exact structure may vary, but typically includes multiple domains that cover:

• 1. Social Interaction
  2. Communication
  3. Restricted and Repetitive Behaviors
  4. Sensory Sensitivities
  5. Cognitive Traits
  6. Emotional Regulation

Administration:

• Can be completed by individuals with autism (self-report), parents, or clinicians, depending on the version.
• Uses a comprehensive rating scale to assess the frequency and intensity of various autistic traits.

Focus:

• Provides a broad and detailed overview of autistic traits across multiple domains.
• Aims to capture the full spectrum of autism-related characteristics for both diagnostic and research purposes.

Advantages:

• Offers a comprehensive assessment of a wide range of autistic traits.
• Useful for identifying strengths and areas of need in individuals with autism.

Limitations:

• Can be more time-consuming due to its comprehensive nature.
• May require detailed knowledge of the individual’s behaviors and traits.

Key Differences

1. Focus:

   • ABC: Focuses on assessing and quantifying specific problem behaviors.
   • CATI: Focuses on providing a comprehensive assessment of a wide range of autistic traits across multiple domains.

2. Structure:

   • ABC: 58 items across five subscales related to problem behaviors.
   • CATI: Multiple domains covering social interaction, communication, repetitive behaviors, sensory sensitivities, cognitive traits, and emotional regulation.

3. Administration:

   • ABC: Typically completed by caregivers or teachers.
   • CATI: Can be completed by individuals with autism, parents, or clinicians, depending on the version.

4. Purpose:

   • ABC: Used for identifying problem behaviors, planning treatment, and monitoring changes over time.
   • CATI: Used for a detailed assessment of autistic traits for both diagnostic and research purposes.

5. Rating Scale:

   • ABC: Uses a Likert scale (0-3) to rate the severity of each behavior.
   • CATI: Uses a comprehensive rating scale to assess the frequency and intensity of various autistic traits.

In Essence, while the ABC is focused on problem behaviors and is useful for clinical treatment planning, the CATI provides a broad and detailed assessment of the full range of autistic traits, making it valuable for both clinical and research applications.

CATI - Comprehensive Autism Trait Inventory

 

• The Comprehensive Autism Trait Inventory (CATI) is a new measure of autistic traits that reflects our current understanding of autism and includes subscales for social camouflage and sensory sensitivity.
• The 42 items are divided into 6 subscales of "Social Interactions,” “Communication,” "Social Camouflage,” "Cognitive Rigidity,” "Repetitive Behaviours,” and "Sensory Sensitivity” (each with 7 items).
• It is free to use.

• (English et al., 2021) is a first validation paper that has included 3 separate studies.
• The CATI showed convergent validity and superior internal reliability compared to existing measures like the AQ and BAPQ
• The CATI provides a comprehensive assessment of trait dimensions associated with autism, potentially eliminating the need for multiple measures, and has the potential to improve research on autistic traits in the general population.

The English et al (2021) article discusses the need for a new measure of autistic traits that reflects our current understanding of autism. The article describes the development and validation of the CATI, comparing it to existing measures such as the Autism-Spectrum Quotient (AQ) and the Broad Autism Phenotype Questionnaire (BAPQ). The CATI demonstrates convergent validity, superior internal reliability, and greater predictive ability for classifying autism compared to the other measures. It is also the first measure to have dedicated subscales for social camouflage and sensory sensitivity. The authors conclude that the CATI provides a reliable and comprehensive assessment of autistic traits, addressing the limitations of existing measures

• (Meng & Xuan, 2023) - A Mandarin Chinese translation of CATI that was recently validated (although only 35 of the 42 items made it into that version, likely due to issues with the model fit of the translated measure). The Chinese group also derived a 24-item short form of the Chinese CATI which appears to have good psychometrics as well.
