Creating the Global Criminal Justice Survey: A Questionnaire Designed to Gather Perspectives from the Autism Community and Criminal Justice Professionals.

The text reports 1618 participants, but Table 2 reports N = 1706, so the analysed sample is unclear. The methods describe an 18-item autism-knowledge measure, but the results describe 17 items, and Table 3 lists 18 items with the first item used only as a screener. The sample was recruited by snowball methods and was largely from the United States, so it may not represent autistic adults, parents/carers or criminal justice professionals globally. The sample was predominantly White and North American, despite the goal of global perspectives. Data were self-report, collected in 2021 during global trauma and stress, and respondents could choose to participate, which may bias answers. The questionnaire was lengthy, which may burden parents/carers and limit participation. The authors did not report differential item functioning across countries or translated versions, so measurement across languages is not yet shown. Autistic adults included both professionally diagnosed and self-identified individuals, so diagnostic status varied.

The paper names the International Society for Autism Research as funder. It also states that the revised Sequential Intercept Model was funded by the International Society for Autism Research.

Do not read this as evidence that the survey improves autism knowledge, police attitudes or criminal justice outcomes. It reports how questionnaire items performed in one large, self-selected sample.
