- A later pooled CAT-PD report included 3,987 people from US clinical, community, university and online samples (mean age 31.6; 54% women; about 70% White, 13% Black and 9% Asian). Most completed the short form, but mixed recruitment settings limit population-wide comparisons.
Review the study used for these details
Scores do not capture culture, minority stress, disability or barriers to support. These factors can shape responses.
The evidence cannot determine whether a questionnaire fits you personally. NuraCheck does not ask for or infer identity to decide this.
