- Continuous variables are presented as M (SD), and categorical variables are presented as N (%). All data in both samples were gathered by self-report
- SPARK Simons Powering Autism Research Knowledge, HPP Human Penguin Project, ADHD attention deficit hyperactivity disorder, TAS Toronto Alexithymia Scale, GAFS-8 8-item General Alexithymia Factor Score
- aParticipants in the HPP sample completed 16 items of the TAS-20, which excluded items 16, 17, 18, and 20. For comparison with the TAS-20 scores in the SPARK sample, these four items were imputed for all HPP participants using random forest imputation
- bCalculated as mean of all 16 non-missing TAS-20 items multiplied by 20, for comparison with TAS-20 scores
