However, a lack of evidence on its factorial structure interferes with score interpretation. To examine whether the currently-available structures of the Theory of Mind Inventory-2 are robust and replicable, confirmatory factor analysis was conducted in 242 children with autism spectrum disorder aged 3-12 years. Two possible structures were examined: the development-based structure, which reflects children's developmental stages of theory of mind (early, basic, and advanced), and the content-based structure, which represents children's social-related functions (emotion recognition, mental state term comprehension, and pragmatics). Four fit indices were adopted simultaneously to examine the model fit of both structures. We found that the development-based structure had a better model fit and was further modified. After modification, the development-based structure showed an improved model fit, but it was not completely acceptable in all fit indices. These findings suggest that the scores of the Theory of Mind Inventory-2 are more appropriate for reflecting children's developmental stages of theory of mind than the social-related functions in children with autism spectrum disorder. However, the domain scores should be cautiously interpreted because the model fits were not completely acceptable. For further revisions, ambiguous terms (e.g., "want" and "need") and confusing concepts assessed by the items (e.g., "recognize" and "understand") could be specified for a better representation of children's developmental stages of theory of mind. Moreover, further validations are needed. LAY SUMMARY: In children with autism spectrum disorder, the scores of the Theory of Mind Inventory-2 are more appropriate for indicating the developmental stages of theory of mind (early, basic, and advanced) than for indicating the social-related functions (emotion recognition, mental state term comprehension, and pragmatics). However, since the factorial validity was not completely acceptable, the domain scores should be interpreted cautiously. Moreover, further revisions and validations are warranted.

Here, we explore the psychometric properties of the Social Communication Questionnaire (SCQ) current version reported at age 8 in a large population-based sample. Using data from the Norwegian Mother, Father and Child Cohort study (MoBa), we perform exploratory (N = 21,775) and confirmatory (N = 21,674) factor analyses on items and compare our results with previously suggested factor structure models of the SCQ. Furthermore, we test for measurement invariance across sex and registry-ascertained autism diagnostic status (Ndiagnosed = 636). A 5-factor model provided best fit to the data in both children with and without autism diagnoses, though with some qualitative differences in what the factors represent across these groups. This model performed largely consistently across boys and girls in the general population. Taken together, the SCQ?s measurement properties must be carefully considered when it is used in population-based samples and measurement invariance testing of other autism screening tools used in similar contexts is warranted. Lay abstract Using questionnaires in research relies on the expectation that they measure the same things across different groups of individuals. If this is not true, then interpretations of results can be misleading when researchers compare responses across different groups of individuals or use in it a group that differs from that in which the questionnaire was developed. For the questionnaire we investigated, the Social Communication Questionnaire (SCQ), we found that parents of boys and girls responded to questionnaire items in largely the same way but that the SCQ measured traits and behaviors slightly differently depending on whether the children had autism. Based on these results, we concluded that researchers using this questionnaire should carefully consider these differences when deciding how to interpret findings. SCQ scores as a reflection of "autism-associated traits" in samples that are mostly or entirely made up of individuals without an autism diagnosis may be misleading and we encourage a more precise interpretation of scores as a broader indication of social-communicative and behavioral traits.
