Mapping the academic problem behaviors of adolescents with ADHD

Effects of Compliance to a Training Intervention for High School Students with ADHD

OBJECTIVE

We evaluated the effects of treatment compliance with the Challenging Horizons Program (CHP) for high school aged adolescents with attention-deficit hyperactivity disorder (ADHD).

METHOD

Participants were 185 high school aged adolescents (65% non-Hispanic White; 79% male) with a diagnosis of ADHD who were randomly assigned to either CHP or community control. Outcomes included parent-rated academic functioning, parent- and self-rated social-emotional functioning, and GPA. The complier average causal effect (CACE) was estimated using propensity-weighted models for youth engaging in ≥ 30 CHP individual sessions (15-20 min) across the academic year.

RESULTS

Most (78%) CHP participants engaged in≥30 CHP sessions. CACE analyses using latent growth curve modeling revealed significant treatment effects among treatment compliers across ratings of academic and social outcomes relative to similar control participants. For most outcomes, CACE estimates were larger than those found in intent-to-treat analyses, especially at 6-months follow-up.

CONCLUSIONS

Compliance with 30 or more individual CHP sessions appeared to be an attainable threshold associated with incremental gains across several academic and social outcomes. Effects of compliance were amplified at 6-months follow-up, supporting the hypothesized theory of change of training interventions. Future work should focus on facilitators of treatment engagement and feasibility of the CHP as delivered by high school personnel.

Examining daily stimulant medication use and sleep in adolescents with ADHD

Research has been inconclusive as to whether stimulant treatment causes or exacerbates sleep problems in adolescents with ADHD. This study examined sleep differences in adolescents with ADHD as a function of stimulant use. Participants were adolescents with ADHD (N = 159, ages 12-14). Parents reported on receipt of stimulant treatment (n = 92, 57.86%; n = 47 amphetamines, n = 45 methylphenidate). Adolescents wore actigraphs and completed daily diaries assessing sleep and daily use of stimulants for 2 weeks. Sleep parameters included daily-reported bedtime, sleep onset latency (SOL), sleep duration, daytime sleepiness, and difficulty waking the following morning; and actigraphy-measured sleep onset time, total time in bed, and sleep efficiency. We estimated between- and within-individual associations between stimulant medication use and sleep indices with all stimulants, after removing adolescents using sleep aids and weekend days, and as a function of stimulant type. Adolescent sleep did not differ between those receiving and not receiving stimulant treatment. Within individuals using stimulants, we largely observed no significant differences between medicated and unmedicated days, though findings were most often significant for school days only. Small effects were found indicating longer SOL, later sleep onset time, and more daytime sleepiness related to medication use. In contrast, there were slight improvements to sleep duration and sleep efficiency related to methylphenidate use, though methylphenidate was also associated with later sleep onset time and more daytime sleepiness. Given the inconsistent and small effects, findings suggest that stimulant medication may impact sleep, but does not appear to be a primary contributor to sleep problems in adolescents with ADHD.

Achieving Independence and Mastery in School: A School-Based Executive Function Group Intervention for Autistic Middle Schoolers

Executive functioning (EF) deficits, such as challenges with planning, organization, and materials management, negatively impact academic performance, particularly for middle-school students with autism spectrum disorder (ASD) without intellectual disability (ID). The aim was to assess the initial efficacy of the school-based version of the Achieving Independence and Mastery in School (AIMS) intervention in a pilot randomized clinical trial. 47 autistic middle-schoolers without ID attending nine different schools were randomized to participate in AIMS or to wait to receive AIMS the following semester (waitlist control = WLC). Youth, caregivers, and teachers rated academic EFs and academic functioning, and youth completed an objective EF measure, at baseline and outcome (post). Effect sizes were computed comparing baseline and post measures within each group. Individuals randomized to AIMS improved from baseline to post on academic EF outcome measures with small to moderate effect sizes, compared to WLC, who made some improvements but with generally smaller effect sizes. Analyses with academic functioning measures showed a similar pattern of results. These promising results suggest that AIMS delivered in the school by school-based personnel to small groups of students with ASD without ID can improve academic EF skills.

Study protocol of a randomized trial of STRIPES: a schoolyear, peer-delivered high school intervention for students with ADHD

BACKGROUND

Youth with ADHD are at risk of academic impairments, dropping out of high school, and dysfunction in young adulthood. Interventions delivered early in high school could prevent these harmful outcomes, yet few high school students with ADHD receive treatment due to limited access to intervention providers. This study will test a peer-delivered intervention (STRIPES) for general education 9th grade students with impairing ADHD symptoms.

METHODS

A type 1 hybrid effectiveness-implementation design will be used to evaluate the effectiveness of STRIPES and explore the intervention's implementability. Analyses will test the impact of STRIPES vs. enhanced school services control on target mechanisms and determine whether differences in basic cognitive profiles moderate intervention response. The acceptability and feasibility of STRIPES and treatment moderators will also be examined.

DISCUSSION

This study will generate knowledge about the effectiveness and implementability of STRIPES, which will inform dissemination efforts in the future. A peer-delivered high school intervention for organization, time management, and planning skills can provide accessible and feasible treatment targeting declines in academic motivation, grades, and attendance during the ninth-grade year.

Attention-deficit hyperactivity symptoms and risk of alcohol use relapse

AIM

Alcohol use disorder (AUD) is frequently accompanied by comorbid attention-deficit hyperactivity disorder (ADHD). Comorbid ADHD has been reported to increase the severity of AUD. We investigated whether ADHD severity also influences AUD relapse risk at baseline and after inpatient treatment.

METHODS

In this study, 187 AUD patients admitted to Narimasu Kosei Hospital from October 2019 to March 2021 were included in the analysis. According to the Adult ADHD Self-Report Scale (ASRS), participants were divided into two groups: ASRS+ with ADHD characteristics (n = 43) and ASRS- with low/no ADHD characteristics (n = 144). Groups were compared for AUD relapse risk at the start of treatment (baseline) and before hospital discharge using the multidimensional Alcohol Relapse Risk Scale (ARRS). The change in relapse risk during hospitalization was also compared by assessment of the interaction between groups (ASRS+ vs. ASRS-) and time (at discharge vs. baseline).

RESULTS

The total ARRS score and dimension subscores for stimulus-induced vulnerability and emotionality problems were significantly higher in the ASRS+ group at baseline and before discharge compared to the ASRS- group. There was a significant group × time interaction indicating less improvement of stimulus-induced vulnerability during inpatient treatment among the ASRS+ group compared to the ASRS- group.

CONCLUSIONS

Our findings suggest that AUD patients with ADHD characteristics have a higher risk of relapse both at baseline and after inpatient treatment. Stimulus-induced vulnerability to relapse is less likely to improve with treatment in patients with ADHD characteristics.

Improving academic performance through a school-based intervention targeting academic executive functions - a pilot study

Background

Academic challenges such as losing/not turning in assignments, misplacing materials, and inefficient studying are common in middle-school students with autism spectrum disorder (ASD) without intellectual disability. Deficits in organization, planning, prioritizing, memory/materials management, and studying skills [i.e. academic executive functioning (EF) deficits] contribute to these challenges.

Objectives

To assess the feasibility, satisfaction, and initial efficacy of the school-based version of the Achieving Independence and Mastery in School (AIMS) intervention in a proof-of-concept trial with 6 students with ASD.

Methods

6 middle-schoolers with ASD without ID participated in AIMS. Parents and teachers rated academic EFs and functioning.

Results

Results suggest high feasibility, youth satisfaction, and improved EF skills and academic behaviors by parent and teacher report.

Conclusion

These promising results support further intervention development and suggest that academic EF skills are malleable in students with ASD.

Mediators of psychosocial treatment for adolescent ADHD

OBJECTIVE

Almost no studies identify mediators of psychosocial interventions for attention deficit/hyperactivity disorder (ADHD)-largely due to design limitations. Understanding mediators can promote streamlined interventions in usual care (UC) settings. When individual studies are insufficient to pursue complex questions, integrative data analysis (IDA) allows researchers to pool raw data from multiple studies to produce cumulative scientific knowledge.

METHOD

We leveraged IDA to pool and harmonize data from four randomized controlled trials of ADHD psychosocial treatment (N = 854) with three time points. Linear growth curve analyses examined the impact of four psychosocial treatment conditions on ADHD symptom outcomes and five candidate mediators (compared to no treatment). To test mediation, we examined whether treatment condition predicted linear growth in the mediator at posttreatment, and if the mediator predicted linear growth in the outcome at follow-up.

RESULTS

Compared to no treatment, engagement-focused parent-teen treatment (d = .43-.72; Supporting Teens' Autonomy Daily [STAND]) and community-based usual care (d = .54-.99) led to greatest reductions in parent-rated ADHD symptoms, followed by the Summer Treatment Program-Adolescent (d = .29-.30; STP-A) and standard behavioral parent training + organization skills training (d = .26-.31; BPT/OST). Improvements in organization, time management, and planning skills mediated outcome for all treatments. BPT/OST and STP-A prevented deterioration of social skills, in turn mitigating escalation of ADHD symptoms. Improvements in parent-teen communication skills mediated outcome for STAND, BPT/OST, and the STP-A. Parent contingency management and disruptive classroom behavior were not treatment mediators.

CONCLUSIONS

Psychosocial treatments for adolescent ADHD primarily improve ADHD symptoms through development of teen organization, time management (OTP), and parent-teen communication skills, as well as slowing deterioration of social skills. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

The Impact of School Strategies and the Home Environment on Home Learning Experiences During the COVID-19 Pandemic in Children With and Without Developmental Disorders

Using the Opportunity-Propensity Model (Byrnes in Dev Rev 56:100911, 2020; Byrnes & Miller in Contemp Educ Psychol 32(4);599–629, 2007), the current study investigated which factors helped predicting children’s home learning experiences during the COVID-19 pandemic, thereby examining differences between children with (DD; n = 779) and without (TD; n = 1443) developmental disorders. MANCOVA results indicated more negative experiences for DD children and their parents. SEM-results revealed the alignment between different teachers and autonomous motivation in children as the most important predictors for the outcome variables. Less predictors were significant for DD as compared to TD children which suggests other factors are at play in the DD group. Limitations, strengths and suggestions for future research are being discussed, together with some implications for classroom practices and remote learning approaches.

Predictors of Treatment Engagement and Outcome Among Adolescents With Attention-Deficit/Hyperactivity Disorder: An Integrative Data Analysis

OBJECTIVE

To identify patient- and treatment-level factors that predict intervention engagement and outcome for adolescents with attention-deficit/hyperactivity disorder (ADHD), guiding efforts to enhance care.

METHOD

Integrative data analysis was used to pool data from 4 randomized controlled trials of adolescent ADHD treatment with participants (N = 854) receiving various evidence-based behavioral therapy packages in 5 treatment arms (standard [STANDARD], comprehensive [COMP], engagement-focused [ENGAGE]), community-based usual care (UC), or no treatment (NOTX). Participants also displayed varying medication use patterns (negligible, inconsistent, consistent) during the trial. Regression and latent growth curve analyses examined treatment- and patient-level predictors of engagement and outcome.

RESULTS

Compared with COMP, ENGAGE was associated with higher parent engagement in behavioral therapy (d = 1.35-1.73) when delivered in university, but not community, clinics. Under some conditions, ENGAGE also predicted youth engagement in behavioral therapy (d = 1.21) and lower likelihood of negligible medication use (odds ratio = 0.49 compared with NOTX). UC was associated with poorer parent engagement compared with COMP (d = -0.59) and negligible medication use (odds ratio = 2.29) compared with NOTX. Compared with COMP, ENGAGE (in university settings) was consistently associated with larger ADHD symptom improvements (d = 0.41-0.83) at 6-month follow-up and sometimes associated with larger grade point average (d = 0.68) and parent-teen conflict (d = 0.41) improvements. Consistent medication use during behavioral therapy was associated with larger improvements in ADHD symptoms (d = 0.28) and parent-teen conflict (d = 0.25-0.36). An ADHD+internalizing clinical profile predicted larger improvements in grade point average (d = 0.45). Family adversity predicted poorer parent and youth engagement (rate ratio = 0.90-0.95), negligible medication use (odds ratio = 1.22), and smaller improvements in grade point average (d = -0.23). African American race predicted smaller improvements in parent-teen conflict (d = -0.49).

CONCLUSION

Engagement-focused behavioral therapy and consistent medication use most frequently predicted stronger clinical engagement and outcomes for adolescents with ADHD. Youths who are African American or who experience family adversity may demonstrate treatment-related disparities for certain outcomes; youths with ADHD+internalizing symptoms may demonstrate excellent academic outcomes following behavioral therapy.

Poor Mental Health in Caregivers of Children with Attention-Deficit/Hyperactivity Disorder and Its Relationships with Caregivers' Difficulties in Managing the Children's Behaviors and Worsened Psychological Symptoms during the COVID-19 Pandemic

The coronavirus disease 2019 (COVID-19) pandemic has thrown out a challenge to caregivers of children with attention-deficit/hyperactivity disorder (ADHD). The present study examined the factors related to the poor general mental health state of the caregivers of children with ADHD during the COVID-19 pandemic, including (1) difficulties of caregivers in asking their child to adopt protective behaviors against COVID-19, (2) difficulties of caregivers in managing the child’s daily performance, and (3) worsened psychological symptoms in children. In total, 161 caregivers completed an online questionnaire to provide data regarding their general mental health state and difficulties in asking their child with ADHD to adopt protective behaviors against COVID-19 and in managing the child’s after-school learning, sleep routine, and internet use, as well as worsened psychological symptoms. The results of multivariate logistic regression analysis demonstrated that caregivers’ difficulties in managing ADHD children’s self-protective behaviors and after-school learning and the children’s worsened emotional symptoms were significantly associated with poor caregiver general mental health state. An intervention that enhances the mental health of caregivers of children with ADHD during the COVID-19 pandemic by addressing their difficulties in managing the children’s behaviors and psychological problems is warranted.

Presenting problem profiles for adolescents with ADHD: differences by sex, age, race, and family adversity

BACKGROUND

Adolescents with attention-deficit/hyperactivity disorder (ADHD) experience developmentally distinct challenges from children and adults with ADHD. Yet no work in this age group identifies treatment-related phenotypes that can inform treatment matching, development of tailored treatments, and screening efforts.

METHOD

This study uses Latent Profile Analysis to detect unique presenting problem profiles among adolescents with ADHD and to test whether these profiles differ by key individual characteristics (age, sex, race, family adversity level). Participants were 854 ethnically diverse adolescents (ages 10-17) from the ADHD Teen Integrative Data Analysis Longitudinal (TIDAL) dataset who were assessed at clinical referral. Parent, adolescent, and teacher ratings, educational testing, and school records measured eight key presenting problems at intake.

RESULTS

A three-profile solution emerged. ADHD simplex (63.7%) was characterized by a mix of the ADHD-Inattentive and ADHD-Combined subtypes, moderate impairment levels, and infrequent comorbidities. ADHD + internalizing (11.4%) was characterized by higher likelihood of comorbid anxiety and/or depression. The disruptive/disorganized ADHD (24.9%) profile was characterized by severe organization, time management, and planning (OTP) problems, the ADHD-Combined subtype, and frequent disruptive behavior at school. Age did not vary across these phenotypes. More females were present in the ADHD + internalizing phenotype; males were more likely to be found in the disruptive/disorganized ADHD phenotype. Higher family adversity and African American race were associated with the disruptive/disorganized ADHD phenotype.

CONCLUSIONS

Adolescents with ADHD demonstrate varying presenting problem phenotypes that vary by sex, family adversity, and race/ethnicity. Consideration of these phenotypes may inform treatment matching and efforts to improve screening among under-diagnosed groups.

Study protocol of a randomised trial of Summer STRIPES: a peer-delivered high school preparatory intervention for students with ADHD

INTRODUCTION

High schoolers with attention-deficit/hyperactivity disorder (ADHD) experience substantial impairments, particularly in the school setting. However, very few high school students with ADHD receive evidence-based interventions for their difficulties. We aim to improve access to care by adapting evidence-based psychosocial intervention components to a low-resource and novel school-based intervention model, Summer STRIPES (Students Taking Responsibility and Initiative through Peer Enhanced Support). Summer STRIPES is a brief peer-delivered summer orientation to high school with continued peer-delivered sessions during ninth grade.

METHODS AND ANALYSIS

Participants will be 72 rising ninth grade students with ADHD who are randomised to receive either Summer STRIPES or school services as usual. Summer STRIPES will be delivered by 12 peer interventionists in a school setting. Outcomes will be measured at baseline, start of ninth grade, mid-ninth grade and end-of-ninth grade. At each assessment, self, parent and teacher measures will be obtained. We will test the effect of Summer STRIPES (compared with school services as usual) on ADHD symptoms and key mechanisms (intrinsic motivation, extrinsic motivation, executive functions) as well as key academic outcomes during the ninth-grade year (Grade Point Average (GPA), class attendance).

ETHICS AND DISSEMINATION

Findings will contribute to our understanding of how to improve access and utilisation of care for adolescents with ADHD. The protocol is approved by the institutional review board at Seattle Children's Research Institute. The study results will be disseminated through publications in peer-reviewed journals and presentations at scientific conferences.

School-based intervention for adolescents with attention-deficit/hyperactivity disorder: Effects on academic functioning

Multi-component training interventions such as the Challenging Horizons Program (CHP) improve organization skills and academic functioning of middle school students with attention-deficit/hyperactivity disorder (ADHD); however, few studies have investigated treatment for high school students. We explored the extent to which CHP adapted for high school would improve proximal (e.g., organization skills, homework performance) and distal (e.g., report card grades) academic outcomes through 6-month follow-up relative to a community care (CC) condition. Participants included 186 adolescents who were randomly assigned to CHP (n = 92; 80% male; M age = 15.0; SD = 0.8) or CC (n = 94; 78% male; M age = 15.1; SD = 0.9) with CHP delivered over one school year. Parent, teacher, and self-report ratings of organization skills and academic performance, report card grades, and achievement tests were collected across multiple occasions. Intent-to-treat analyses using hierarchical linear modeling revealed significant improvements of small to medium magnitude (d range = 0.32 to 0.58) for parent-rated organization skills, homework performance, and academic functioning at 6-month follow-up. CHP effect on grades was small, but associated with a less steep decline than that found for CC. No statistically significant effects on teacher or self-report ratings were obtained. CHP appears efficacious for ameliorating organization skills and homework performance deficits exhibited by high school students with ADHD and can protect against decline in report card grades experienced by these students. CHP may require supplementation with academic skills instruction for some students and may need implementation beyond one school year to produce durable effects.

An integrated program of computer-presented and physical cognitive training exercises for children with attention-deficit/hyperactivity disorder

BACKGROUND

This study integrated an experimental medicine approach and a randomized cross-over clinical trial design following CONSORT recommendations to evaluate a cognitive training (CT) intervention for attention deficit hyperactivity disorder (ADHD). The experimental medicine approach was adopted because of documented pathophysiological heterogeneity within the diagnosis of ADHD. The cross-over design was adopted to provide the intervention for all participants and make maximum use of data.

METHODS

Children (n = 93, mean age 7.3 +/- 1.1 years) with or sub-threshold for ADHD were randomly assigned to CT exercises over 15 weeks, before or after 15 weeks of treatment-as-usual (TAU). Fifteen dropped out of the CT/TAU group and 12 out of the TAU/CT group, leaving 66 for cross-over analysis. Seven in the CT/TAU group completed CT before dropping out making 73 available for experimental medicine analyses. Attention, response inhibition, and working memory were assessed before and after CT and TAU.

RESULTS

Children were more likely to improve with CT than TAU (27/66 v. 13/66, McNemar p = 0.02). Consistent with the experimental medicine hypotheses, responders improved on all tests of executive function (p = 0.009-0.01) while non-responders improved on none (p = 0.27-0.81). The degree of clinical improvement was predicted by baseline and change scores in focused attention and working memory (p = 0.008). The response rate was higher in inattentive and combined subtypes than hyperactive-impulsive subtype (p = 0.003).

CONCLUSIONS

Targeting cognitive dysfunction decreases clinical symptoms in proportion to improvement in cognition. Inattentive and combined subtypes were more likely to respond, consistent with targeted pathology and clinically relevant heterogeneity within ADHD.

Effectiveness of Motivational Interviewing-Enhanced Behavior Therapy for Adolescents With Attention-Deficit/Hyperactivity Disorder: A Randomized Community-Based Trial

OBJECTIVE

This study tests the effectiveness of parent-teen psychotherapy for adolescent attention-deficit/hyperactivity disorder (ADHD) (Supporting Teens' Autonomy Daily [STAND]) versus usual care (UC) in 4 community clinics.

METHOD

A randomized clinical trial was conducted with double randomization of adolescents and therapists to STAND versus UC. Participants were 278 culturally diverse adolescents diagnosed with DSM-5 ADHD at baseline and 82 community therapists. Seven primary outcomes were assessed at baseline (BL), posttreatment (PT; mean = 5.11 months post-BL, SD = 2.26), and follow-up (FU; mean = 9.81 months post-BL, SD = 2.50): inattention (IN; parent/teacher-rated), academics (parent-rated/official records), family functioning (parent/adolescent-rated), and disciplinary records. Treatment engagement indicated consumer fit (eg, number or sessions received, percentage of sessions attended by parent, satisfaction). The impact of treatment on concurrent medication use was also examined. Service delivery features were examined as moderators of outcome.

RESULTS

Intent-to-treat (N = 278) analyses indicated no significant group × time effects. STAND only led to superior outcomes when therapists were licensed (22% of sample) versus unlicensed (parent-rated IN: p < .001, d = 1.08; parent-rated academic impairment: p = .010, d = 1.17). Compared to UC, STAND was associated with greater parent participation (p < .001, d = 0.88) and higher scores on certain indices of parent satisfaction. STAND also was associated with superior medication engagement over time compared to UC (odds ratio = 7.18).

CONCLUSION

Evidence-based psychosocial treatment for adolescent ADHD did not outperform UC on outcome trajectories despite improving some indices of treatment engagement. STAND requires additional adaptation for community contexts.

Association Between Hyperactivity Symptoms and Somatic Complaints: Mediating and Moderating Mechanisms in Childhood Trauma and Life Events Among Chinese Male Adolescents

Background: Prior research has found that attention deficit/hyperactivity disorder (ADHD) - particularly hyperactivity symptoms - is associated with various somatic complaints. The present study further tests the relationship between hyperactivity symptoms and somatic complaints in Chinese male adolescents and explores the underlying moderating and mediating mechanisms. Methods: Our sample included 1,586 males (age = 12-16) recruited as part of an epidemiological study of child and adolescent mental disorders from April to July, 2014. Hyperactivity symptoms and somatic complaints were assessed with Achenbach's Child Behavior Checklist (CBCL), and the Childhood Trauma Questionnaire Short Form (CTQ-SF) and Adolescent Life Events Scale (ASLEC) were used to assess exposure to childhood trauma and recent life events. Results: Adolescents with hyperactivity symptoms experienced more emotional abuse, physical abuse, life events, and reported more somatic complaints symptoms (p < 0.0083 or p < 0.05). Linear regression analysis showed that hyperactivity, total childhood trauma score/emotional abuse and sexual abuse and ASLEC score significantly predicted somatic complaints (all p < 0.05). Emotional abuse and life events mediated the relationship between hyperactivity symptoms and somatic complaints. Furthermore, childhood trauma moderated the path between hyperactivity symptoms and ASLEC in the moderation mediation model for predicting somatic complaints (p < 0.05). Conclusions: Hyperactivity symptoms had a significant impact on somatic complaints among Chinese male adolescents. Furthermore, childhood trauma and life events affected the relationship between hyperactivity symptoms and somatic complaints. Interventions for somatic complaints in male adolescents with hyperactivity symptoms should thus consider history of childhood trauma and life events.

Remote Learning During COVID-19: Examining School Practices, Service Continuation, and Difficulties for Adolescents With and Without Attention-Deficit/Hyperactivity Disorder

PURPOSE

This study examined remote learning practices and difficulties during initial stay-at-home orders during the COVID-19 pandemic in adolescents with and without attention-deficit/hyperactivity disorder (ADHD).

METHODS

Participants were 238 adolescents (132 males; 118 with ADHD) aged 15.64-17.99 years and their parents. Adolescents and parents completed questionnaires in May/June 2020 when in-person schools were closed in the U.S.

RESULTS

Twenty-two percent of families incurred financial costs to support remote learning, and only 59% of school-based services received before COVID-19 continued during COVID-19 remote learning. Adolescents with ADHD had fewer routines and more remote learning difficulties than adolescents without ADHD. Parents of adolescents with ADHD had less confidence in managing remote learning and more difficulties in supporting home learning and home-school communication. Thirty-one percent of parents of adolescents with ADHD with an Individualized Education Program (IEP) or receiving academic accommodations (504 Plan) reported remote learning to be very challenging, compared with 18% of parents of adolescents with ADHD without an IEP/504 Plan, and only 4% of parents of adolescents with neither ADHD nor an IEP/504 Plan. Fewer adolescent routines, higher negative affect, and more difficulty concentrating because of COVID-19 were each associated with greater adolescent remote learning difficulties only in adolescents with ADHD.

CONCLUSIONS

This study provides initial findings of the nature and impact of remote learning during the COVID-19 pandemic. It is imperative for schools and communities to provide the necessary supports to adolescents, particularly those with mental health and/or learning difficulties, and to their parents.

Four-Year Follow-Up of High versus Low Intensity Summer Treatment for Adolescents with ADHD

OBJECTIVE

Despite an emergence of psychosocial treatments for adolescent ADHD, their long-term effects are unknown.

METHOD

We examine four-year outcomes of a randomized controlled trial (N = 218) comparing high-intensity (HI; 412 h, $4,373 per participant) versus low-intensity (LI; 24 h, $97 per participant) skills-based summer intervention delivered to adolescents with ADHD at two secondary school transitions (6th/9th grade). Quantitative and qualitative analyses evaluated group×time and group×grade×time effects on 4-year outcomes.

RESULTS

Relative to LI, a single dose of HI had modest but lasting effects on teen organization skills (d =.40) and ADHD symptoms (9th grade only: d =.27 to.31) at 4-year follow-up. There was no long-term incremental effect of HI (vs. LI) for parent-teen conflict, GPA, or parent use of contingency management. Treatment appeared most effective when delivered to older adolescents (i.e., 9th versus 6th grade), suggesting the long-term impact of ADHD treatment may increase with age. Qualitative data corroborated that the primary long-term benefit of HI (vs. LI) treatment was to organization skills; many of the remaining perceived benefits were to parent and teen psychological variables (i.e., increased self-esteem, self-awareness, parental optimism). HI offered no incremental benefit to long-term educational or clinical service utilization or costs.

CONCLUSIONS

Modest therapeutic benefits of adolescent ADHD treatment are maintained long term. However, HI treatment did not impact outcomes that could defray the intervention's high costs ($4,373) compared to LI treatment ($97).

The ADHD teen integrative data analysis longitudinal (TIDAL) dataset: background, methodology, and aims

BACKGROUND

The Attention Deficit Hyperactivity Disorder (ADHD) Teen Integrative Data Analysis Longitudinal (TIDAL) dataset integrates data from four randomized trials.

METHOD

Participants with ADHD (N = 854; 72.5% male, 92.5% racial/ethnic minority, ages 10-17) were assessed three times across 12 months. Data includes parent, self, and teacher ratings, observations, and school records. The battery was harmonized using an Integrative Data Analysis (IDA) approach to form variables that assign unique values to all participants.

RESULTS

The data will be used to investigate: (1) profiles that organize the heterogeneous population into clinically meaningful subgroups, (2) whether these profiles predict treatment response, (3) heterogeneity in treatment response and variables that predict this response, (4) how treatment characteristics and adjunctive supports predict treatment response, and (5) mediators of treatment and whether these mechanisms are moderated by treatment characteristics.

CONCLUSIONS

The ADHD TIDAL Dataset will be openly shared with the field to maximize its utility.

Metacognitive and motivation deficits, exposure to trauma, and high parental demands characterize adolescents with late-onset ADHD

The objective of this study is to evaluate support for three hypotheses about the etiology of adolescent-onset ADHD symptoms: (1) a "cool" cognitive load hypothesis, (2) a "hot" rewards processing hypothesis, and (3) a trauma exposure hypothesis. Participants (N = 50) were drawn from two public high schools in a culturally diverse metropolitan area. A detailed procedure for identifying and confirming late-onset ADHD cases is described. Adolescents with late-onset ADHD (n = 15) were identified and compared to childhood-onset (n = 17) and non-ADHD classmates (n = 18). Adolescents and parents completed measures of neurocognition, rewards' processing, clinical profile, and environmental demands. Late-onset cases were clinically and neurocognitively indistinguishable from childhood-onset cases; however, they experienced higher demands from parents (d = 1.09). Compared to the non-ADHD group, late-onset cases showed significant deficits in metacognition (d = 1.25) and academic motivation (d = 0.80), as well as a pronounced history of multiple trauma exposure (OR 11.82). At 1-year follow-up, ADHD persisted in 67.7% of late-onset cases. Late-onset cases (26.7%) were more likely than childhood-onset cases (0.0%) to transfer to alternative schools by 1-year follow-up. Multiple factors may contribute to adolescent-onset ADHD. Adolescents with metacognition and motivation deficits may be at greatest risk for the late-onset ADHD phenotype, particularly in highly demanding environments. Exposure to traumatic stress may play a key role in the exacerbation of existing deficits or onset of new symptoms. Late-onset ADHD was persistent in most cases and associated with higher risk for school disengagement than childhood-onset ADHD. Further work is needed to better understand the etiologies of late-onset ADHD symptoms.

Sensory processing and organisational abilities in children with inattentive-hyperactive behaviours

Background/Aims

Sensory processing has been theorised to contribute to object and temporal organisation. Sensory processing and organisational abilities in children with inattention-hyperactivity was assessed, and investigated if there was a relationship between the two.

Methods

A community sample of children aged 9–12 years was categorised into inattentive-hyperactive (n=20) and non-inattentive-hyperactive groups (n=56) using the Vanderbilt Attention Deficit Hyperactivity Disorder Parent and Teacher Rating Scales. The Sensory Profile, Child Organisation Scale and Child Organisation Parent Perception Scale were used to collect additional data.

Results

Sensory processing and organisational abilities differed significantly between the groups. Object organisation correlated significantly with multisensory processing; temporal organisation failed to correlate with sensory processing.

Conclusions

Results suggest there is a need to screen children with informant-reported inattention-hyperactivity for sensory processing differences and organisational deficits. Sensory processing and object organisation may be associated; further research on potential factors underlying this association is needed.

Academic impairment among high school students with ADHD: The role of motivation and goal-directed executive functions

Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with academic failure in high school; however the underpinnings of these difficulties are insufficiently understood. This study examined deficits in self-regulated learning in a sample of high school students with ADHD (n = 32) compared to demographically similar classmates without ADHD (n = 18). A multimethod battery of self and parent rating scales and cognitive tasks measured aspects of intrinsic motivation, extrinsic motivation, and goal-directed executive functions. A multiple regression modeled predictors of current Grade Point Average (GPA). Results indicated that high school students with ADHD placed lower value on academics (d = .99), were less likely to use goal-setting strategies (d = .95), possessed lower levels of metacognition (d = 1.86), and showed significant deficits in task-based cognitive flexibility (d = .80). After controlling for covariates, the set of self-regulated learning variables explained 23% of the variance in GPA, with metacognition (6% of variance explained) and cognitive flexibility (7% of variance explained) serving as significant predictors of outcome. Findings suggest that higher-order executive function deficits play a critical role in the academic functioning of high school students and students with ADHD show large deficits in these areas. Thus, interventions that target metacognition and cognitive flexibility (i.e., the ability to think through decisions before acting, inhibit automatic responses, and make effective decisions for a desired goal) may be particularly promising to remediate ADHD-related academic problems in high school.

Sleep and daytime sleepiness in adolescents with and without ADHD: differences across ratings, daily diary, and actigraphy

BACKGROUND

Children with attention-deficit/hyperactivity disorder (ADHD) experience greater sleep problems than their peers. Although adolescence is generally a developmental period characterized by insufficient sleep, few studies have used a multi-informant, multi-method design, to examine whether sleep differs in adolescents with and without ADHD.

METHODS

Targeted recruitment was used to enroll an approximately equal number of eighth-grade adolescents (mean age = 13 years) with (n = 162) and without ADHD (n = 140). Adolescents and parents completed global ratings of sleep problems; adolescents, parents, and teachers completed ratings of daytime sleepiness. Adolescents wore actigraphs and completed a daily sleep diary for approximately 2 weeks.

RESULTS

Adolescents with ADHD were more likely than adolescents without ADHD to obtain insufficient sleep on school days (per diary) and weekends (per diary and actigraphy). Adolescents with ADHD were also more likely to report falling asleep in class and to have stayed up all night at least twice in the previous 2 weeks (14% and 5% reported all-nighters for ADHD and comparison, respectively). In regression analyses controlling for a number of variables known to impact sleep (e.g. pubertal development, sex, medication use, having an externalizing, anxiety, or depression diagnosis), ADHD remained associated with shorter diary and actigraphy school night sleep duration, adolescent- and parent-reported daytime sleepiness, and parent-reported difficulties initiating and maintaining sleep and total sleep disturbance. Controlling for other variables, the odds of being classified with clinically elevated parent-reported sleep disturbance were 6.20 times greater for adolescents with ADHD.

CONCLUSIONS

Findings provide some of the clearest evidence yet that adolescents with ADHD experience more sleep problems and sleepiness than their peers without ADHD. It may be especially important to assess for sleep problems in adolescents with ADHD and to evaluate whether existing sleep interventions are effective, or can be optimized, for use in adolescents with ADHD who also have sleep problems.

High versus Low Intensity Summer Treatment for ADHD Delivered at Secondary School Transitions

Spikes in symptom severity are noted for adolescents with attention deficit/hyperactivity disorder (ADHD) at the transitions to middle and high school that are attributed to developmental maladjustment. This study evaluated the effectiveness of high-intensity (HI; 412 hr, $4,373 per participant) versus low-intensity (LI; 24 hr, $97 per participant) skills-based summer intervention delivered to adolescents with ADHD by local school district staff. Participants were 325 ethnically diverse rising sixth and ninth graders with ADHD randomized to HI versus LI (n = 218) or recruited into an untreated comparison group (n = 107). Group × Time 1-year outcome trajectories were compared using linear mixed models. Both interventions possessed high fidelity and were viewed by families as enjoyable and beneficial. Youth attendance was higher for HI (~80%) versus LI (~45%). Parent training attendance was uniform across groups (~50%). Parent and student attendance did not impact trajectories. Primary benefits of HI over LI were to note taking (d = .50), parent contingency management (d = .43), and parent-rated ADHD symptoms (d = .40-.46; ninth grade only). Secondary analyses suggested that HI may produce additional benefits compared to no treatment for home organization skills (HI vs. untreated d = .54), parent-teen conflict (HI vs. untreated d = .39), and grade point average (HI vs. untreated d = .47, ninth grade only). Summer HI treatment was superior to LI in engagement and uptake of certain skills. However, the extent to which these medium benefits on a limited number of outcomes justify high costs compared to LI remains an open question. Delivering treatment during the summer instead of school year may limit generalizability.

Parent-Teen Group versus Dyadic Treatment for Adolescent ADHD: What Works for Whom?

The goal of this study was to evaluate the comparative efficacy of 2 clinic-based psychosocial treatment modalities for adolescent attention deficit/hyperactivity disorder (ADHD) and identify characteristics that facilitate patient-modality matching. Culturally diverse adolescents with ADHD (N = 123) were randomized to 1 of 2 versions of a parent-teen psychosocial treatment for ADHD (Supporting Teens' Autonomy Daily [STAND]): (a) group parent and adolescent skills training or (b) dyadic skills training blended with motivational interviewing. Participants were assessed at baseline, posttreatment, and 6-month follow-up on ADHD symptom severity and functional treatment targets. Differences in therapy process and cost were documented. Modality differences in outcome were examined using linear mixed and general linear models. Each modality successfully engaged the proposed therapy processes. Dyadic and group STAND produced equivalent overall outcomes. However, the dyadic modality demonstrated superior efficacy when parents had elevated ADHD or depression symptoms or high conflict with the teen. Families with lower parent education level and higher parental depression showed lower overall attendance; married parents were more likely to attend dyadic STAND (vs. group). Naturalistic stimulant medication did not influence treatment outcome. At less than one third of the cost of dyadic treatment, group models may be an economical option for treating parents and adolescents with ADHD. Screening adolescents with ADHD for parental psychopathology and parent-teen conflict may allow clinics to match higher risk patients to more personalized approaches that can enhance efficacy.

Relational impairments, sluggish cognitive tempo, and severe inattention are associated with elevated self-rated depressive symptoms in adolescents with ADHD

This study examines how ADHD-related symptoms and impairments interact to predict depression symptoms in young adolescents with ADHD. A sample of 342 adolescents (71% male, mean age = 13 years old) with DSM-IV-TR diagnosed ADHD completed baseline clinical assessments upon entry to a psychosocial treatment study for ADHD. Ratings of ADHD and sluggish cognitive tempo (SCT) symptoms, and social and academic impairment were obtained from parents, while ratings of depressive symptoms and conflict with parents were obtained from youth. Among adolescents with ADHD, elevated depressive symptoms were associated with higher SCT symptom severity, lower hyperactive/impulsive (HI) symptom severity, higher social impairments, higher conflict with parents, and lower academic problems. Interaction effects indicated that clinically significant depressive symptoms were most likely to occur when high levels of parent-youth conflict were present along with high inattentive (IN) symptoms, high SCT, and/or low HI. Among children and adolescents with ADHD, depression prevention efforts might target IN/SCT symptom management, as well as improving interpersonal relationships with parents and peers. Future work is needed to verify these findings longitudinally.

Metacognitive interventions in text production and working memory in students with ADHD

This study compared the effects of two metacognitive interventions on writing, working memory (WM), and behavioral symptoms of students with attention-deficit/hyperactivity disorder (ADHD). The disorder was clinically diagnosed by a multidisciplinary team according to DSM-IV criteria. The first approach consisted of a combined intervention in text production and WM while the second focused only on WM. Participants were 47 students from the fifth to ninth grades of two public elementary schools in Porto Alegre (Brazil), randomized to one of the two interventions groups. Writing and WM were assessed before, immediately after, and 3 months after the interventions. The results suggest that both interventions contributed to improving behavior and school performance, whereas only the combined intervention increased the overall quality of narrative text, organization of paragraphs, and denouement.

Delivering Parent-Teen Therapy for ADHD through Videoconferencing: A Preliminary Investigation

Adolescents with ADHD demonstrate notoriously poor treatment utilization. Barriers to access have been partially addressed through tailored therapy content and therapist delivery style; yet, additional challenges to engaging this population remain. To leverage modern technology in support of this aim, the current study investigates parent-teen therapy for ADHD delivered over a videoconferencing format. In this preliminary feasibility study, teens and parents (N=20) received an empirically supported dyadic therapy that incorporates skills-based modules with motivational interviewing. The videoconferencing interface was deemed feasible with nearly all families completing treatment. Acceptable therapeutic alliance was reported and key mechanisms of change were engaged (i.e., adolescent motivation to meet goals, parent strategy implementation). Families reported high satisfaction, despite minor disturbances associated with delivering therapy via videoconferencing. Treatment integrity and fidelity were acceptable, though slightly reduced compared to clinic-based trials of the same protocol. Therapists perceived that videoconferencing enhanced treatment for 50% of families. Reductions in participant ADHD symptoms and organization, time management, and planning problems from baseline to post-treatment were noted by parents and teachers. However, open trial results of this study should be interpreted with caution due to their uncontrolled and preliminary nature.

Reexamining ADHD-Related Self-Reporting Problems Using Polynomial Regression

Individuals with attention deficit hyperactivity disorder (ADHD) underreport symptoms compared with informants and objective measures. This study applied enhanced statistical methodology (polynomial regression) to the study of ADHD self-reporting to clarify what contributes to symptom underreporting by adolescents with ADHD ( N = 107; ages = 11-15 years). Polynomial regression models were conducted to test competing hypotheses about the nature of self-reporting problems. Traditional difference score models were nested within polynomial regression models to examine how modeling strategy influences results. Sixty-six percent of the sample substantially underreported symptoms compared with parents and 23.6% denied all symptoms. Polynomial regression models provided no evidence that the size of the discrepancy between parent and adolescent symptom reports possessed meaningful linear associations with any of the hypothesized predictors. Nested models indicated that the difference score approach led to very poor model fit and increased risk for Type I errors when examining underreporting among youth with ADHD. This finding suggests that past evaluations using a difference score approach should be replicated using polynomial regression to ensure that significant effects do not represent statistical artifact.

Social Functioning in Children With or At Risk for Attention Deficit/Hyperactivity Disorder: A Meta-Analytic Review

Considerable work has demonstrated significant impairment in social functioning for children with attention deficit/hyperactivity disorder (ADHD). The social functioning profiles of children with ADHD are marked by impairments across diverse domains as they tend to experience greater rates of peer rejection, have lower levels of social skills, and have impaired social cognitions. The purpose of this study was to (a) quantitatively examine the association between ADHD and deficits across several domains of social functioning (peer functioning, social skills, social information processing), (b) examine differences in the magnitude of such associations, and (c) examine the effect of potential moderators. A meta-analysis of 109 studies (n = 104,813) revealed that children with ADHD have the most impairment within the peer functioning domain (weighted effect size [ES] r = .33) followed by significantly smaller effects within the social skills (weighted ES r = .27) and social information-processing domains (weighted ES r = .27). When examining potential moderators, results revealed that the association between ADHD and deficits within the social skills domain was weaker among studies that controlled for co-occurring conduct problems (CP). Studies that utilized sociometric and teacher reports of peer status reported the largest effects within the peer functioning domain. In addition, studies that utilized the "gold standard" approach to diagnosing ADHD documented the largest effects within both the social skills and peer functioning domains. Last, studies utilizing younger samples revealed the largest effects for deficits within the peer functioning domain. Theoretical and clinical implications are discussed.

Meta-analysis of organizational skills interventions for children and adolescents with Attention-Deficit/Hyperactivity Disorder

BACKGROUND

In addition to problems with attention and hyperactivity, children with ADHD present with poor organizational skills required for managing time and materials in academic projects. Organizational skills training (OST) has been increasingly used to address these deficits. We conducted a systematic review and meta-analysis of OST in children with ADHD.

OBJECTIVES

The objective of this study was to systematically review the evidence of the effects of OST for children with ADHD for organizational skills, attention, and academic performance.

METHODS

We searched 3 electronic databases to locate randomized controlled trials published in English in peer-reviewed journals comparing OST with parent education, treatment-as-usual, or waitlist control conditions. Standardized mean difference effect sizes from the studies were statistically combined using a random-effects meta-analyses across six outcomes: teacher- and parent-rated organizational skills, teacher- and parent-rated inattention, teacher-rated academic performance, and Grade Point Average (GPA). Risk of bias was assessed for randomization, allocation concealment, blinding of participants and treatment personnel, blinding of outcome assessors, incomplete outcome data, and selective outcome reporting.

RESULTS

Twelve studies involving 1054 children (576 treatment, 478 control) were included in the meta-analyses. Weighted mean effect sizes for teacher- and parent-rated outcome measures of organizational skills were g=0.54 (95% CI 0.17 to 0.91) and g=0.83 (95% CI 0.32 to 1.34), respectively. Weighted mean effect sizes of teacher- and parent-rated symptoms of inattention were g=0.26 (95% CI 0.01 to 0.52) and g=0.56 (95% CI 0.38 to 0.74), respectively. Weighted standardized mean effect size for teacher-rated academic performance and GPA were g=0.33 (95% CI 0.14 to 0.51) and g=0.29 (95% CI 0.07 to 0.51), respectively.

CONCLUSIONS

OST leads to moderate improvements in organizational skills of children with ADHD as rated by teachers and large improvements as rated by parents. More modest improvements were observed on the ratings of symptoms of inattention and academic performance.

A school consultation intervention for adolescents with ADHD: barriers and implementation strategies

BACKGROUND

Academic impairment is among the most troubling domains of impairment for adolescents with Attention Deficit/Hyperactivity Disorder (ADHD).

METHOD

This investigation presents results of a yearlong academic intervention delivered to adolescents with ADHD (N = 218) by engaging school staff as interventionists through behavioral consultation with an outside mental health professional.

RESULTS

The intervention was coordinated successfully in some cases, but not in others. The principal challenge to intervention coordination was sustaining monthly contact between consultants and interventionists (38.5% success rate) and scheduling in-person consultation meetings with interventionists (40.0% success rate). Implementation of the intervention was enhanced when the student (a) attended a public (vs. private) school, (b) had an IEP or Section 504 plan in place, (c) was in middle school (vs. high school), (d) had a parent who communicated regularly with the school, and (e) had a special education support staff member or counselor (vs. teacher or administrator) as a school interventionist.

CONCLUSIONS

Considering these data, recommendations are provided for effective coordination of academic interventions for adolescents with ADHD.

Predictors of Informant Discrepancies Between Mother and Middle School Teacher ADHD Ratings

A diagnosis of attention-deficit/hyperactivity disorder (ADHD) according to the Diagnostic and Statistical Manual, 5th Eldition (DSM-5) is assessed in youth using ratings from both a parent and a teacher. However, individual and contextual differences between informants may lead to discrepancies in these ratings. The purpose of this study was to examine predictors of discrepancies between mother and middle school teacher reports of ADHD symptoms and related impairment. In an ethnically diverse sample of middle school students with well-diagnosed DSM-IV-TR ADHD (N = 112), we examined a range of mother and school setting characteristics that may contribute to informant discrepancies in this population. Hierarchical multiple regression analyses suggested that mothers with higher levels of education and psychopathology (i.e., ADHD symptom severity, parenting stress) may be most likely to report adolescent ADHD symptom severity that is higher than reported by teachers. Reports from general education teachers (vs. special education) were associated with lower symptom severity compared to mothers. Finally, a documented diagnosis of ADHD in the school was predictive of more severe reports from mothers. We discuss explanations for these findings and implications for assessment of middle school students with ADHD.

Longitudinal evaluation of the importance of homework assignment completion for the academic performance of middle school students with ADHD

The primary goal of this study was to longitudinally evaluate the homework assignment completion patterns of middle school age adolescents with ADHD, their associations with academic performance, and malleable predictors of homework assignment completion. Analyses were conducted on a sample of 104 middle school students comprehensively diagnosed with ADHD and followed for 18 months. Multiple teachers for each student provided information about the percentage of homework assignments turned in at five separate time points and school grades were collected quarterly. Results showed that agreement between teachers with respect to students assignment completion was high, with an intraclass correlation of .879 at baseline. Students with ADHD were turning in an average of 12% fewer assignments each academic quarter in comparison to teacher-reported classroom averages. Regression analyses revealed a robust association between the percentage of assignments turned in at baseline and school grades 18 months later, even after controlling for baseline grades, achievement (reading and math), intelligence, family income, and race. Cross-lag analyses demonstrated that the association between assignment completion and grades was reciprocal, with assignment completion negatively impacting grades and low grades in turn being associated with decreased future homework completion. Parent ratings of homework materials management abilities at baseline significantly predicted the percentage of assignments turned in as reported by teachers 18 months later. These findings demonstrate that homework assignment completion problems are persistent across time and an important intervention target for adolescents with ADHD.

Parent Management of Organization, Time Management, and Planning Deficits among Adolescents with ADHD

Organization, Time Management, and Planning (OTP) problems are a key mechanism of academic failure for adolescents with ADHD. Parents may be well positioned to promote remediation of these deficits; yet, almost nothing is known about OTP management behaviors among parents of middle and high school students with ADHD. In a sample of 299 well-diagnosed adolescents with ADHD, a measure of parental OTP management was psychometrically validated. Latent Class Analysis was conducted to detect distinct patterns of parental OTP management and yielded four unique classes: Parental Control (18.7 %), Parent-Teen Collaboration (20.4 %), Homework Assistance (20.4 %), and Uninvolved (40.5 %). Logistic Regression analyses indicated that maladaptive parental OTP strategies were related to higher levels of parent and adolescent psychopathology. Parental OTP management did not relate to current adolescent OTP skills or GPA, indicating that parents did not select OTP management strategies in immediate response to adolescent functioning. Implications for parent-directed intervention are discussed.

ADHD symptomatology is best conceptualized as a spectrum: a dimensional versus unitary approach to diagnosis

The aim of this paper is to build a case for the utility of conceptualizing ADHD, not as a unitary disorder that contains several subtypes, but rather as a marker of impairment in attention and/or impulsivity that can be used to identify one of several disorders belonging to a spectrum. The literature will be reviewed to provide an overview of what is known about ADHD in terms of heterogeneity in symptomatology, neuropsychology, neurobiology, as well as comorbidity with other diseases and treatment options. The data from these areas of research will be critically analyzed to support the construct of a spectrum of disorders that can capture the great variability that exists between individuals with ADHD and can discriminate between separate disorders that manifest similar symptoms. The symptoms associated with ADHD can be viewed as dimensional markers that point to a spectrum of related disorders that have as part of their characteristics impairments of attention and impulsivity. The spectrum can accommodate symmetrically and asymmetrically comorbid psychiatric disorders associated with ADHD as well as the wide heterogeneity known to be a part of the ADHD disorder. Individuals presenting with impairments associated with ADHD should be treated as having a positive marker for a spectrum disorder that has as part of its characteristics impairments of attention and/or impulsivity. The identification of impairment in attention and/or impulsivity should be a starting point for further testing rather than being an endpoint of diagnosis that results in pharmacological treatment that may or may not be the optimal therapy. Rather than continuing to attribute a large amount of heterogeneity in symptom presentation as well as a high degree of symmetric and asymmetric comorbidity to a single disorder, clinical evaluation should turn to the diagnosis of the type of attentional deficit and/or impulsivity an individual has in order to colocate the individual's disorder on a spectrum that captures the heterogeneity in symptomatology, the symmetrical and asymmetrical comorbidity, as well as subthreshold presentation and other variants often worked into the disorder of ADHD. The spectrum model can accommodate not only the psychophysiological profiles of patients, but is also consistent with what is known about the functional heterogeneity of the prefrontal cortex as well as the construct that cognitive processes are supported by overlapping and collaborative networks.
