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.
