What kinds of questionnaires are administered?
The questionnaires for both studies (the Genetic Linkage/Association Study of Tourette Syndrome and the Family Genetic Study of TS, ADHD and OCD) gather information about social behaviors and psychiatric history. Additional questionnaires for the Family Genetic Study consist of questions relating to sensory sensitivity, attention and impulsivity, executive functioning, organization, and other behaviors. If you participate in both studies, you will only need to complete the questionnaires once. Please note that all information is kept confidential.
