PTSD in autistic adults: Correlates of meeting DSM-5 criteria and predictors of professional diagnosis.

Objective: Although many autistic adults show high posttraumatic stress, PTSD is underdiagnosed in this population. This study aims to examine correlates of autistic adults screening positive for PTSD (PTSD +) and predictors of a professional PTSD diagnosis (Diagnosis +) in the PTSD + subgroup.

Method: Self-identified autistic adults ( = 677) completed an online survey on their demographic characteristics, mental health symptoms, and trauma history.

Interpersonal Trauma and Posttraumatic Stress in Autistic Adults.

Background: Many autistic adults report interpersonal traumas (IPTs) such as physical or sexual assault, which are often associated with posttraumatic stress and dissociation. Factors such as gender might make autistic individuals particularly vulnerable to experiencing IPT and negative posttraumatic symptoms.

Methods: In this study, 687 self-identified autistic adults completed an online survey on their traumatic experiences and mental health symptoms.

Dual-Task Processing With Identical Stimulus and Response Sets: Assessing the Importance of Task Representation in Dual-Task Interference.

Limitations in our ability to produce two responses at the same time - that is, dual-task interference - are typically measured by comparing performance when two stimuli are presented and two responses are made in close temporal proximity to when a single stimulus is presented and a single response is made. While straightforward, this approach leaves open multiple possible sources for observed differences. For example, on dual-task trials, it is typically necessary to identify two stimuli nearly simultaneously, whereas on typical single-task trials, only one stimulus is presented at a time.
