Change in Behavior Problems from Childhood Through Adolescence for Children with Fragile X Syndrome

Abstract

In this study, we examined trajectories of specific domains of behavior problems (i.e., attention problems, depression/anxiety, and aggressive behavior) from age 6 to 18 in a sample of 55 children with fragile X syndrome. We also examined autism status and early parenting as predictors of subsequent behavioral trajectories. We found that attention problems and aggressive behavior declined steadily from childhood through adolescence whereas anxious/depressed behavior demonstrated relative stability over the same period. Youth with highly flexible mothers displayed more optional trajectories of improvement in attention problems.
