Symons, Frank J.; Byiers, Breanne J.; Raspa, Melissa; Bishop, Ellen; Bailey, Donald B., Jr. – American Journal on Intellectual and Developmental Disabilities, 2010
We used National Fragile X Survey data in order to examine reported self-injurious behavior (SIB) to (a) generate lifetime and point prevalence estimates, (b) document detailed features of SIB (frequency, types, location, severity) in relation to gender, and (c) compare comorbid conditions between matched pairs (SIB vs. no SIB). Results indicate…
