Journal ArticleDOI
The separation of between-person and within-person components of individual change over time: a latent curve model with structured residuals.
TL;DR: This article proposes and demonstrates a novel extension of the multivariate latent curve model to allow for the disaggregation of between-person differences in change and obtains a specificity of results from the proposed analytic strategy that is not available from other existing methodologies.
Journal ArticleDOI
Adolescent Substance Use in the Multimodal Treatment Study of Attention-Deficit/Hyperactivity Disorder (ADHD) (MTA) as a Function of Childhood ADHD, Random Assignment to Childhood Treatments, and Subsequent Medication
Brooke S.G. Molina,Stephen P. Hinshaw,L. Eugene Arnold,James M. Swanson,William E. Pelham,Lily Hechtman,Betsy Hoza,Jeffery N. Epstein,Timothy Wigal,Howard Abikoff,Laurence L. Greenhill,Peter S. Jensen,Karen C. Wells,Benedetto Vitiello,Robert D. Gibbons,Andrea L. Howard,Patricia R. Houck,Kwan Hur,Bo Lu,Sue M. Marcus +19 more
TL;DR: The results suggest the need to identify alternative or adjunctive adolescent-focused approaches to substance abuse prevention and treatment for boys and girls with ADHD, especially given their increased risk for use and abuse of multiple substances that is not improved with stimulant medication.
Journal ArticleDOI
Functional Adult Outcomes 16 Years After Childhood Diagnosis of Attention-Deficit/Hyperactivity Disorder: MTA Results.
Lily Hechtman,James M. Swanson,Margaret H. Sibley,Annamarie Stehli,Elizabeth B. Owens,John T. Mitchell,L. Eugene Arnold,Brooke S.G. Molina,Stephen P. Hinshaw,Peter S. Jensen,Howard Abikoff,Guillermo Perez Algorta,Andrea L. Howard,Betsy Hoza,Joy Etcovitch,Sylviane Houssais,Kimberley D. Lakes,J. Quyen Nichols +17 more
TL;DR: Adult functioning after childhood ADHD varies by domain and is generally worse when ADHD symptoms persist, so it is important to identify factors and interventions that promote better functional outcomes.
Journal ArticleDOI
Young adult outcomes in the follow‐up of the multimodal treatment study of attention‐deficit/hyperactivity disorder: symptom persistence, source discrepancy, and height suppression
James M. Swanson,L. Eugene Arnold,Brooke S.G. Molina,Margaret H. Sibley,Lily Hechtman,Stephen P. Hinshaw,Howard Abikoff,Annamarie Stehli,Elizabeth B. Owens,John T. Mitchell,Quyen Nichols,Andrea L. Howard,Laurence L. Greenhill,Betsy Hoza,Jeffrey H. Newcorn,Peter S. Jensen,Benedetto Vitiello,Timothy Wigal,Jeffery N. Epstein,Leanne Tamm,Kimberly D. Lakes,James G. Waxmonsky,Marc Lerner,Joy Etcovitch,Desiree W. Murray,Maximilian Muenke,Maria T. Acosta,Mauricio Arcos-Burgos,William E. Pelham,Helena C. Kraemer +29 more
TL;DR: In the MTA follow-up into adulthood, the ADHD group showed symptom persistence compared to local norms from the LNCG, and within naturalistic subgroups of ADHD cases, extended use of medication was associated with suppression of adult height but not with reduction of symptom severity.
Journal ArticleDOI
Defining ADHD symptom persistence in adulthood: optimizing sensitivity and specificity
Margaret H. Sibley,James M. Swanson,L. Eugene Arnold,Lily Hechtman,Elizabeth B. Owens,Annamarie Stehli,Howard Abikoff,Stephen P. Hinshaw,Brooke S.G. Molina,John T. Mitchell,Peter S. Jensen,Andrea L. Howard,Kimberley D. Lakes,William E. Pelham +13 more
TL;DR: The interview format optimizes young adult self-reporting when parent reports are not available, and the combination of parent and self-reports from rating scales, using an 'or' rule and a NB threshold optimized the balance between sensitivity and specificity.
