Specificity, contexts, and reference groups matter when assessing autistic traits.

Area of Science:

• Psychology
• Neurodevelopmental Disorders
• Psychometrics

Background:

• Autistic traits assessed via questionnaires can be influenced by social context and reference groups.
• Understanding these influences is crucial for accurate trait assessment in autistic and non-autistic populations.

Purpose of the Study:

• To investigate how specifying context and reference groups affects the self-reporting of autistic traits.
• To determine if these factors differentially influence autistic versus non-autistic individuals' responses.

Main Methods:

• Two experiments were conducted with autistic and non-autistic participants.
• Experiment 1 manipulated the context (in-group vs. out-group) for the Broad Autism Phenotype Questionnaire.
• Experiment 2 manipulated the reference group (in-group vs. out-group) for the Social Responsiveness Scale.

Main Results:

• Specifying context influenced self-reported autistic traits for both groups; out-group context increased reported traits, while in-group context decreased them.
• Specifying reference group significantly impacted autistic participants' self-reports, with out-group references increasing reported traits and in-group references decreasing them.
• Non-autistic participants showed less sensitivity to reference group changes. Unspecified assessments defaulted to a non-autistic majority as the implied context and reference group.

Conclusions:

• Context and reference group are critical variables in the accurate assessment of autistic traits.
• Questionnaire design and interpretation must account for social context and reference group effects.
• Future research should consider these factors to improve the validity of autism trait measures.
