Working memory and organizational skills problems in ADHD.

ABSTRACT: BACKGROUND:This study tested model-driven predictions regarding working memory's role in the organizational problems associated with ADHD. METHOD:Children aged 8-13 (M = 10.33, SD = 1.42) with and without ADHD (N = 103; 39 girls; 73% Caucasian/Non-Hispanic) were assessed on multiple, counterbalanced working memory tasks. Parents and teachers completed norm-referenced measures of organizational problems (Children's Organizational Skills Scale; COSS). RESULTS:Results confirmed large magnitude working memory deficits (d = 1.24) and organizational problems in ADHD (d = 0.85). Bias-corrected, bootstrapped conditional effects models linked impaired working memory with greater parent- and teacher-reported inattention, hyperactivity/impulsivity, and organizational problems. Working memory predicted organization problems across all parent and teacher COSS subscales (R2 = .19-.23). Approximately 38%-57% of working memory's effect on organization problems was conveyed by working memory's association with inattentive behavior. Unique effects of working memory remained significant for both parent- and teacher-reported task planning, as well as for teacher-reported memory/materials management and overall organization problems. Attention problems uniquely predicted worse organizational skills. Hyperactivity was unrelated to parent-reported organizational skills, but predicted better teacher-reported task planning. CONCLUSIONS:Children with ADHD exhibit multisetting, broad-based organizational impairment. These impaired organizational skills are attributable in part to performance deficits secondary to working memory dysfunction, both directly and indirectly via working memory's role in regulating attention. Impaired working memory in ADHD renders it extraordinarily difficult for these children to consistently anticipate, plan, enact, and maintain goal-directed actions.

Project description:BackgroundProblems with sustained attention, impulsivity, and hyperactivity are the most prominent symptoms of attention-deficit hyperactivity disorder (ADHD), but many children with this diagnosis also present with poor organizational skills that are important in relation to school. These problems tend to increase from childhood to adolescence and are often not well managed by medication. Organizational skills training (OST) is a range of behavioral interventions that specifically target organizational skills deficits. Evidence supports the effect of OST on improving organizational skills, inattention, and academic performance in children with ADHD. Because previous clinical trials included mostly children above the age of 8 years, this trial includes children in the age range 6-13 years to expand the knowledge on the effects of OST in younger children. Previous OST research has also shown improvement on inattention in parent ratings; we will investigate if a change in inattention can be confirmed with neurocognitive tests. Finally, little is known about predictors of treatment response in OST.ObjectivesThe primary objective is to investigate if OST has positive effects on organizational skills in children with ADHD. The primary outcome measurement is the parent-rated Children's Organizational Skills Scale (COSS), collected before and at the end of the 10 week intervention. Secondary and exploratory outcomes include inattention ratings, family and school functioning, and cognitive functions measured before the intervention period, immediately after, and at a 6 month follow-up. Additional objectives are to investigate both neurocognitive outcomes and age as predictors of treatment response.MethodsThis is a randomized clinical superiority trial investigating the effect of OST vs a treatment-as-usual (TAU) control group for children with ADHD in the age range of 6-13 years. All participants (n = 142) receive TAU. OST is administered in a group format of 10 weekly sessions. Adverse events are monitored by study clinicians during weekly therapy sessions and all assessments. Data analyses will be conducted using mixed linear regression models with random intercepts for patients, adjusted for the stratification variables and the baseline value.PerspectivesThis study will provide important new knowledge and expand on existing research in the field of non-pharmacological treatment of children with ADHD. OST can potentially have a significant impact on the lives of children with ADHD by helping them learn how to cope with their present deficits and to become more independent and self-reliant. It is also important to investigate predictors of treatment response in order to optimize OST.Trial registrationClinicalTrials.gov NCT03160378 . Registered on May 19, 2017.
