## Abstract

PROJECT SUMMARY
Neurodevelopmental disorders such as attention-deficit/hyperactivity disorder (ADHD) emerge during early
childhood and are more prevalent in males. In contrast, anxiety and mood disorders commonly emerge during
adolescence and are more frequent in females. However, our understanding of the mechanisms that underlie
sex differences in the occurrence of various forms of psychopathology is limited. The Research Domain
Criteria (RDoC) project provides a dimensional and transdiagnostic framework as an alternative to our
traditional categorical conceptualization of psychiatric disorders in order to better characterize the full range of
typical to atypical functioning and to better understand sex differences and comorbidity. It is critical to consider
RDoC constructs within the context of development, particularly when examining disorders that emerge in
childhood and often progress to increasingly severe forms or new comorbidities later in development. Further,
given evidence of sex differences in the developmental course of psychopathology and trajectories of brain
development, longitudinal research is necessary to understand whether biobehavioral markers of internalizing
and externalizing psychopathology differ across development for girls and boys. The proposed study will
leverage neuroimaging and behavioral data from existing longitudinal studies to examine the effect of sexual
dimorphism on the development of motor, emotional, and cognitive control from early childhood through
adolescence (ages 4-17 years) among a large sample of children with ADHD (n=329) and typically developing
controls (n=273). There is considerable evidence that ADHD lies at the extreme of a continuous dimension
rather than a discrete syndrome with clear boundaries between disorder and health. Motor, cognitive, and
emotional control systems, thought to develop in parallel, are implicated in the pathophysiology of ADHD and
other neuropsychiatric disorders. Furthermore, ADHD is often comorbid with other disorders in childhood and
girls and boys with ADHD experience differential risk for deleterious outcomes in adolescence and adulthood.
Therefore, studying developmental changes in dimensional RDoC constructs among a sample of children with
and without ADHD will inform our understanding of sex differences in psychopathology more broadly defined.
We propose to compare the developmental trajectories of cognitive, emotional, and motor control both in terms
of behavior and neuroanatomy, and to relate these trajectories to externalizing and internalizing symptoms
using dimensional analyses. This study will draw from and integrate data across two ongoing longitudinal
studies: one of preschool children (age 4-5 years at time 1; n=145) followed into middle childhood and a
second large sample of (confirmed) pre-pubertal 8-12 year-old children (n=437), a subset of whom have
completed longitudinal follow-up visits in adolescence (ages 12-17; n=106). Combining these datasets p...
