Clinical Correlates of Restrictive Type Attention Deficit Hyperactivity Disorder in Adolescents

Abstract

Introduction: Clinical correlates of the proposed restrictive type attention deficit hyperactivity disorder (ADHD/R) is not well established in adolescents. There is still controversy on the validity of ADHD/R as a distinct entity from ADHD predominantly inattentive (ADHD/I). This study aims to define the clinical symptoms of ADHD/R and compare of ADHD/R with other sub - types of ADHD in adolescents. Methods: A total of 87 adolescents (mean: 143 months, 73.5% male) with a DSM-V ADHD diagnosis were included in the study. ADHD subtypes, including the proposed ADHD/R, were diagnosed based on clinical interview, parental reports, and teacher reports. Study measures included the Turgay DSM-IV based ADHD rating Scale (T-DSM-IV-S) parent and teacher forms, conners’ parent rating scale (CPRS), and Conners’ teacher rating scale revised. Results: Thirty-nine adolescents (44.8%) had ADHD combined (ADHD/C), 33 (37.9%) had ADHD/I, and 15 (17.2%) had ADH- D/R subtype. Regarding gender, no significant difference was found between ADHD/I and ADHD/R. Regarding the par - ent-rated scales; the total, hyperactivity, conduct problems, and oppositional scores of T-DSM-IV-S; and the total, hyperac- tivity and learning problems scores of CPRS were found to be higher in adolescents with ADHD/I when compared to those with ADHD/R (p
