Differences in social vulnerability among individuals with autism spectrum disorder, Williams syndrome, and Down syndrome

Although individuals with disabilities are at increased risk of victimization, few studies examine persons with different disability conditions to determine whether distinctive cognitive-behavioral profiles are associated with different levels of social vulnerability. To determine the differences in social vulnerability and experiences of victimization, caregiver responses to a Social Vulnerability Questionnaire were examined for 103 caregivers of individuals with autism spectrum disorder (ASD), Williams syndrome (WS), and Down syndrome (DS). Although all three groups experienced similar rates and types of victimization, the specific correlates of social vulnerability differed by disability. Individuals with ASD displayed less risk awareness and had less social protection; those with WS were rated higher on risk factors related to perceived vulnerability and parental independence; and those with DS had less risk awareness and were perceived to be more vulnerable. Safety interventions should be tailored to address each group's specific correlates of social vulnerability.
