The tools with the strongest psychometric properties are described below: There are few well-established and empirically-validated measures to assess ASD. Trauma as a result of an assault is associated with a higher risk for developing ASD than other types of trauma (9,10). Factors that elevate the risk of developing ASD are past psychiatric disorders, prior trauma, greater trauma severity, avoidant coping, high neuroticism, and being female (8). While many studies have examined factors that place individuals at risk for developing PTSD, only a handful of studies have examined risk factors for the development of ASD. ![]() Currently, there are no prevalence estimates of ASD in adults using DSM-5criteria. Of note, these rates are based on DSM-IV ASD criteria. For example, prevalence estimates of ASD range from 13 - 21% following motor vehicle accidents and 14% after brain injury (5) to 24% following assault (6) and 59% following rape (7). Some trauma types are associated with higher rates of ASD than others. Regardless of whether an individual goes on to develop PTSD, a diagnosis of ASD is important so that individuals experiencing early significant distress in response to a trauma can be identified and treated.īack to Top How Common Is ASD Following Trauma Exposure?ĪSD prevalence rates vary in trauma exposed populations across studies and across different trauma types, with an average of 19% (1). However, not all individuals who meet criteria for ASD will go onto develop PTSD, and many individuals who develop PTSD do not first have an ASD diagnosis (3). Is ASD Predictive of PTSD? How Common Is ASD Following Trauma Exposure? Who Is at Risk for ASD? How is ASD diagnosed? What Are Effective Treatments for ASD? References Is ASD Predictive of PTSD?ĪSD is a risk factor for developing subsequent PTSD (1). See Bryant's (2016) comprehensive text on ASD (1) for a thorough discussion of the differences between ASD and PTSD.
