SCQ - Social Communication Questionnaire

Lexicon [Measures] - SCQ 

The Social Communication Questionnaire (SCQ) is a caregiver-reported questionnaire that evaluates social communication and interaction patterns in individuals suspected of being autistic. It was derived from the Autism Diagnostic Interview-Revised (ADI-R). It is designed for use with children and adults who have a mental age [see post on why "mental age" is problematic] of at least 2 years and 6 months. It is often used as a screening tool in clinical and research settings. [See posts on other Screening/Diagnostic Measures].

Limitations:

• The SCQ is a screening tool and should not be used as a standalone diagnostic instrument. A comprehensive evaluation by a trained clinician using multiple assessment methods is necessary for a formal autism diagnosis.
• Co-occurring Conditions: Many individuals with ASD may have co-occurring conditions such as intellectual disabilities, language impairments, ADHD, anxiety, or sensory processing difficulties. The SCQ focuses specifically on social communication and interaction and may not fully capture the range of challenges associated with co-occurring conditions such as language challenges, ADHD, anxiety or sensory processing.
• Caregiver reports are subject to biases and inaccuracies, as they rely on the caregiver's observations and interpretations of the individual's behaviors.
• Caregivers' ability to accurately report on specific social communication behaviors and experiences of nonspeaking autistics may be limited.
• The SCQ is not designed to assess other developmental disabilities apart from ASD.

Berkeley News

UC Berkeley Chancellor Christ retires next year. 

Can't help but remember that had handed me my University Medal finalist award on stage at convocation along with a lovely message. I think she became chancellor around the time I joined Cal.

NASEM: Cultivating Accessible Educational Pathways and Spaces

 

Event by National Academies of Sciences, Engr and Medicine. 

Disrupting Ableism and Advancing STEM:  

Cultivating Accessible Educational Pathways and Spaces 

THURSDAY, JUNE 15, 2023, 

I was on the the panel that runs from 1:35pm ET - 2:15pm ET

Recording link 

"This virtual session is a critical element of Disrupting Ableism and Advancing STEM: Cultivating Accessible Educational Pathways and Spaces, the fourth event in the five-part Disrupting Ableism and Advancing STEM conversation series.  Overall, this event in the series will focus on the important role of education in preparing students with disabilities as they enter the STEM ecosystem.  Discussions will focus on the need to challenge assumptions about who can learn and succeed in STEM and the need to make direct changes to policies and practices to facilitate positive educational experiences for students. Examples will include asset based approaches to learning in classrooms, laboratories, online, and in the field. 

Got a nice feedback email today. 

"My name is ____ and I work at a medical university in a northern town in ___Ontario Canada. I saw your presentation today on cultivating accessible educational pathways and spaces. I was completely blown away by your presentation. What you have accomplished is incredibly impressive. I not only applaud you but the professors who went out of their way to make labs accessible for you. I think as a medical school, we are behind the ball so to speak with regards to accommodating the needs of those with different abilities....... This entire series has been fascinating to me. Thank you for sharing."

Review v Meta Analysis

I continue to learn....as I navigate grad school

Review vs Meta-Analysis

A review paper /literature review, provides a comprehensive overview and evaluation of existing research on a particular topic. It involves gathering information from multiple sources, such as research articles, books, and other relevant publications, and synthesizing the findings to summarize the current state of knowledge on the topic. Review papers typically do not involve statistical analysis or original data collection.

A meta-analysis is a specific type of research synthesis that involves combining and analyzing quantitative data from multiple studies to generate more robust conclusions. Researchers identify relevant studies, extract relevant data from each study, and statistically analyze the combined data to derive overall effect sizes or estimates of the relationship between variables. Meta-analyses often include a systematic review of the literature as a first step to identify relevant studies for inclusion.

Ed Levels and dx age

 I came across an intriguing fact today. 

Individuals who get an ADHD diagnosis in childhood tend to attain lower levels of education than individuals who get an ADHD in adulthood (Wymbs & Dawson-2015).

I wonder if there is a parallel in autism too. Do autistics who get dx in childhood have lower ed levels than autistics who get dx in adulthood. (though I could not see much research on this)

I would think so - cuz despite the claim that you get better access to childhood autism therapy (most of which does not work by the way), you also end up facing a lot of gatekeeping from an educational system that fundamentally starts off with a view of lower exceptions of anyone with a disability dx, which means you are often kept out of mainstream education, gatekeeped out of opportunities than those without a dx would have access to if they chose to pursue it. We are not even given that option of opportunities as everything and everyone around you indicates over and over that you are incapable of more than just surviving and being pushed up and out of the school system (parallels to the school-prison pipeline in minority communities). 

All this constant stigma and discrimination takes a toll on mental health, self-esteem, and motivation. If the ed foundational legs at the basic school level is non-supportive and discouraging, there is no motivation to complete and attempt yet another potentially demotivating/discouraging environment. 

Ironically I find that though it's a lot more work/effort (the disability part), ed is actually much more non-judgmental and freeing at college level compared to school, but you have to first navigate the school system; a step many may not be able to cross, to even make it to college.

Proprioceptive feedback

Proprioceptive feedback has been studied in the context of Autism to understand its potential role in the motor impairments and sensory processing differences and altered personal space.

Proprioceptive feedback refers to the sensory information that our body receives regarding the position, movement, and orientation of our body parts. It is a crucial component of our overall perception and awareness of our body in space. This feedback allows us to have a sense of where our body is located, how it is moving, and how our limbs are positioned without having to visually observe them.

Proprioception is mediated by specialized receptors known as proprioceptors, which are found in muscles, tendons, ligaments, and joints. These proprioceptors detect changes in muscle length, muscle tension, joint angles, and joint pressure. They provide constant input to the central nervous system, particularly the brain and spinal cord, enabling us to have a continuous sense of our body's position and movement.

Examples of proprioceptors

• the muscle spindle located within skeletal muscles, responds to changes in muscle length. When a muscle is stretched or contracted, the muscle spindle sends signals to the CNS, providing information about the degree and speed of muscle stretch. This information helps the brain monitor and control muscle activity, contributing to coordinated movement.
• Golgi tendon organ, located at the junction between muscles and tendons, responds to changes in muscle tension or force exerted on the tendon. When muscle tension increases, the Golgi tendon organ detects this change and sends signals to the central nervous system, allowing for adjustments in muscle force and preventing excessive muscle contraction.
• Joint receptors  found in the capsules and ligaments surrounding joints,  detect changes in joint position and movement. There are different types of joint receptors, including Ruffini corpuscles, Pacinian corpuscles, and free nerve endings, each specialized for different aspects of joint movement. These receptors provide information about joint angles, joint velocity, and joint pressure, allowing for precise control of limb movements.

Proprioceptive feedback is integrated with other sensory information, such as visual and vestibular input, to provide a comprehensive perception of body position and movement. The brain combines these different sensory inputs to create a coherent representation of the body in space, known as body schema.

Research has shown that proprioception plays a vital role in motor control, coordination, and balance. Impairments in proprioceptive feedback can lead to difficulties in performing precise movements, maintaining balance, and coordinating multiple body parts. For example, individuals with certain neurological conditions or injuries affecting proprioceptive pathways may experience problems with coordination and a reduced awareness of their body's position, potentially leading to increased risk of falls or accidents.
