Effects of Childhood and Adult Persistent Attention-Deficit/Hyperactivity Disorder on Risk of Motor Vehicle Crashes: Results From the Multimodal Treatment Study of Children With Attention-Deficit/Hyperactivity Disorder.

Objective: To determine motor vehicle crash (MVC) risk in adults with a history of childhood attention-deficit/hyperactivity disorder (ADHD) and persistent ADHD symptoms.

Method: Participants with (n = 441) and without (n = 239; local normative comparison group) childhood ADHD from the Multimodal Treatment of Attention-Deficit/Hyperactivity Disorder (MTA) Study were included. Participants provided self-reports on total number of MVCs they had been involved in and the time of licensure.

Young adult outcomes in the follow-up of the multimodal treatment study of attention-deficit/hyperactivity disorder: symptom persistence, source discrepancy, and height suppression.

Background: The Multimodal Treatment Study (MTA) began as a 14-month randomized clinical trial of behavioral and pharmacological treatments of 579 children (7-10 years of age) diagnosed with attention-deficit/hyperactivity disorder (ADHD)-combined type. It transitioned into an observational long-term follow-up of 515 cases consented for continuation and 289 classmates (258 without ADHD) added as a local normative comparison group (LNCG), with assessments 2-16 years after baseline.

Methods: Primary (symptom severity) and secondary (adult height) outcomes in adulthood were specified.

Functional Adult Outcomes 16 Years After Childhood Diagnosis of Attention-Deficit/Hyperactivity Disorder: MTA Results.

Objective: To compare educational, occupational, legal, emotional, substance use disorder, and sexual behavior outcomes in young adults with persistent and desistent attention-deficit/hyperactivity disorder (ADHD) symptoms and a local normative comparison group (LNCG) in the Multimodal Treatment Study of Children with ADHD (MTA).

Method: Data were collected 12, 14, and 16 years postbaseline (mean age 24.7 years at 16 years postbaseline) from 476 participants with ADHD diagnosed at age 7 to 9 years, and 241 age- and sex-matched classmates.

Exploration of the Factor Structure of ADHD in Adolescence through Self, Parent, and Teacher Reports of Symptomatology.

Factor analytic studies of attention-deficit/hyperactivity disorder (ADHD) in children and adults have shown that second-order and bifactor models better represent ADHD symptoms than two- or three-factor models, yet there is far less evidence for a bestfitting model of ADHD in adolescence. Thus, the current study examined the factor structure of ADHD in adolescence and further evaluated the external validity of the best fitting model. Participants were 588 adolescents (22 % female; 366 with a childhood ADHD diagnosis; mean age 15.

Comparison of On-Road Driving Between Young Adults With and Without ADHD.

Objective: This study compared video recordings from routine driving of ADHD and non-ADHD young adults to identify differences in driving behaviors.

Method: A matched sample of young adult drivers with and without ADHD are compared via blinded ratings of videoed g-force events recorded by DriveCam technology over 3 months of on-road driving.

Results: ADHD drivers were significantly more likely to have more crashes, minor events, and g-force events.
