- Abstract
We investigated the prevalence and phenomenology of repetitive behavior in genetic syndromes to detail profiles of behavior. The Repetitive Behaviour Questionnaire (RBQ) provides fine-grained identification of repetitive behaviors. The RBQ was employed to examine repetitive behavior in Angelman ( N = 104), Cornelia de Lange ( N = 101), Cri-du-Chat ( N = 58), Fragile X ( N = 191), Prader-Willi ( N = 189), Lowe ( N = 56) and Smith-Magenis ( N = 42) syndromes and individuals with intellectual disability of heterogeneous aetiology ( N = 56). Repetitive behavior was variable across syndromes. Fragile X syndrome scored highly on all subscales. Angelman syndrome demonstrated a significantly lowered probability for most behaviors. Prader-Willi, Cri-du-Chat and Smith-Magenis syndrome evidenced unique profiles of repetitive behavior. There is extreme heterogeneity of repetitive behavior across genetic syndromes, highlighting syndrome specific profiles.
