  • December 2016 - Sibling Stress Survey
    Researchers at Virginia Tech conducted a nationwide, online survey to examine stress and perceived support among adolescent siblings of individuals with autism spectrum disorder (ASD) and Down syndrome (DS). Siblings completed measures of perceived support from family and friends, their relationship with their brother or sister with ASD or DS, the level of challenging behaviors in the brother/sister, overall levels of personal stress, and stress due to specific parts of their life.
    Importantly, there were no group differences on perceived support from family and friends or the sibling relationship. That is, siblings of individuals with ASD and siblings of individuals with DS both feel equally supported by friends and family and reported equally close relationships with their brother or sister. Additionally, the groups reported no significant differences on most sources of stress, including academics, social life, romantic life, family, environment, and personal health (scores for individual stressors were on a scale from 0-100).
    However, siblings of individuals with Down syndrome reported significantly less overall stress and significantly less stress due to their brother/sister than did siblings of individuals with ASD. At first, it seemed that this difference might be a result of the higher level of brother/sister behavior problems reported by siblings of individuals with ASD, but further statistical analyses showed that group membership (e.g. Down syndrome vs. autism spectrum disorder) predicted total stress levels even when controlling for brother/sister behavior problems. It is important to note that the overall stress scale had possible scores of 0-40, meaning that the group averages indicated mild to moderate levels of stress.
    Full results from this study are currently being written up for publication in academic journals. Please direct any questions to Dr. Carolyn Shivers, lead researcher (shivercm@vt.edu).
  • January 2017 - “A predictive model for obstructive sleep apnea and Down syndrome," American Journal of Medical Genetics Part A.
