Research from Penn State College of Medicine, reported in EurekAlert, suggests that those with autism are more prone to suicidal ideation than non-autistic youth. The researchers looked at achievement and cognitive ability, as well as various demographic variables. The four most significant demographic variables were Black or Hispanic, 10 years old or older, socioeconomic status and male. Interestingly, cognitive ability was not a significant predictor, but depression was. The results were published in the January issue of Research in Autism Spectrum Disorders.
