However, the nature of this relationship has not yet been fully elucidated. The aims of this study were to evaluate the relationship between AT and PTSD and to investigate which specific autistic dimension was more associated with trauma and stress-related symptoms.<\/jats:p><\/jats:sec><jats:sec id=\"S1092852924000014_sec2\" sec-type=\"methods\"><jats:title>Methods<\/jats:title><jats:p>A total of 68 subjects with ASD and 64 healthy controls (HCs) were assessed with the Adult Autism Subthreshold Spectrum (AdAS Spectrum) and the Trauma and Loss Spectrum (TALS) questionnaires.
