Improved but still impaired: symptom-impairment correspondence among youth with attention-deficit hyperactivity disorder receiving community-based care

Receiver operating characteristic curve analysis of the Weiss Functional Impairment Rating Scale-Parent Report for screening children with ADHD: Looking beyond symptoms in ADHD diagnosis

AIM

The current study aimed at examining the ability of the Weiss Functional Impairment Rating Scale-Parent Report (WFIRS-P) to discriminate between children with ADHD and controls in functional impairment and identifying optimal cutoff scores for the WFIRS-P subscales and total scale.

METHODS

Parents of 51 children with ADHD (90.2% male; grades 1-6) and 51 gender/grade matched controls (90.2% male; grades 1-6) completed the WFIRS-P. Receiver operating characteristic (ROC) curve analysis was used to examine the ability of the WFIRS-P to differentiate children with ADHD from controls and to determine optimal cutoff scores of the WFIRS-P.

RESULTS

Area under the curve (AUC) was 0.98 for the WFIRS-P total scale, indicating excellent ability to differentiate children with ADHD from controls. The score of 0.45 with 0.88 for sensitivity and 0.96 for specificity was determined as the optimal cutoff score for the total scale of the WFIRS-P. AUC was 0.73 to 0.97 for the WFIRS-P subscales, suggesting good to excellent ability for discriminating between children with ADHD and controls. Among the subscales, the family subscale score of 0.42 with 0.92 for sensitivity and 0.96 for specificity showed the highest discriminating power. The self-concept and life skills subscales had low sensitivity, suggesting Iranian mothers do not identify problems with self-concept or difficulty with life skills as particularly problematic in ADHD.

CONCLUSIONS

The WFIRS-P is a sensitive and specific measure of the functional impairment associated with ADHD in Iranian children. Our sample was predominantly male, limiting the generalizability of results to females.

Etiological Networks of Attention-Deficit/Hyperactivity Disorder during Childhood and Adolescence

OBJECTIVE

The purpose of the current study was to use network analysis techniques to parse relations between attention-deficit/hyperactivity disorder (ADHD) symptom domains, domains of executive function, and temperament traits.

METHODS

Participants were 420 children aged 6-17 years (55% boys). The majority of the participants were Caucasian (72.86%) and 50% of the sample met diagnostic criteria for ADHD. Both parents and teachers provided ratings of participants' ADHD symptom severity. Parents completed questionnaires pertaining to participants' temperament traits, and participants completed well-validated laboratory measures of executive function.

RESULTS

Results suggested effortful control as demonstrating the strongest relations with ADHD, particularly the parent-reported inattentive symptom domain. Additionally, negative effects appeared to demonstrate weaker but still notable relations primarily with the parent-reported hyperactive/impulsive symptom domain. Measures of executive function did not appear to demonstrate relations with any measures of ADHD symptoms or temperament traits. The results were generally replicated in a distinct sample (n = 732, 7-13 years, 63% boys, 81% White), although differences emerged pertaining to the role of surgency (i.e., related to the hyperactive/impulsive symptom domain in the replication but not the primary sample).

CONCLUSIONS

Overall, findings provided support for the primary role of effortful control, as well as secondary roles for negative affect and surgency, as key risk markers for the characterization of ADHD. Additional exploration of the overlap between temperament and executive function, as pertaining to ADHD, may help clarify heterogeneity in phenotypes and suggest priorities for targeted interventions outside of traditional symptoms.

Data-Driven Methods for Predicting ADHD Diagnosis and Related Impairment: The Potential of a Machine Learning Approach

Current diagnostic criteria for ADHD include several symptoms that highly overlap in conceptual meaning and interpretation. Additionally, inadequate sensitivity and specificity of current screening tools have hampered clinicians' ability to identify those at risk for related outcomes. Using machine learning techniques, the current study aimed to propose a novel algorithm incorporating key ADHD symptoms to predict concurrent and future (i.e., five years later) ADHD diagnosis and related impairment levels. Participants were 399 children with and without ADHD; multiple informant measures of ADHD symptoms, global impairment, academic performance, and social skills were included as part of an accelerated longitudinal design. Results suggested eight symptoms as most important in predicting impairment outcomes five years later: (1) Has difficulty sustaining attention in tasks or play activities, (2) Does not follow through on instructions and fails to finish work, (3) Has difficulty organizing tasks and activities, (4) Avoids tasks (e.g., schoolwork, homework) that require sustained mental effort, (5) Is often easily distracted, (6) Is often forgetful in daily activities, (7) Fidgets with hands or feet or squirms in seat, and (8) Interrupts/intrudes on others. The algorithm comprising this abbreviated list of symptoms performed just as well as or significantly better than one comprising all 18 symptoms in predicting future global impairment and academic performance, but not social skills. It also predicted concurrent and future ADHD diagnosis with 81-93% accuracy. Continued development of screening tools will be key to ensuring access to clinical services for youth at risk for ADHD.

Higher treatment focus diffusion in Multisystemic Therapy is associated with less functional improvement over the course of treatment

PURPOSE

Treatment focus diffusion (TFD), dividing focus across multiple concerns during treatment, is common in public mental health care and differs from the more narrowly focused empirically supported treatments for youth reported in the literature. The present study examined whether and to what extent TFD is associated with youth functional improvement over the course of therapy.

METHOD

This study utilized multi-level modeling techniques to analyze 12 consecutive years of standardized routine clinical service data from youth receiving treatment in one of two intensive in-home service settings: (a) Multisystemic Therapy (MST; n = 776 youths, 99 therapists), an implemented evidence-based treatment based on ecological theories of behavior in which therapists work with the multiple systems a youth interacts with (school, community, family), and (b) a standards-based service (n = 1854 youth, 413 therapists). Both service settings operate in the context of a publicly funded mental health care system which serves youth and families who are typically from underserved and low-income backgrounds. Majority of youth in this sample identified as multi-ethnic and male, and they, on average, were approximately 13 years old with three co-occurring diagnoses.

RESULTS

A significant TFD by service format interaction on youth functional improvement (alone and in the overall model) and follow up simple effects indicated that higher TFD was associated with significantly poorer outcomes in MST. The parameter estimate for TFD on functional improvement in the standards-based service format was in the same direction, but not statistically significant.

CONCLUSION

Our findings suggest that maintaining a narrower treatment focus might be beneficial to clients, particularly in implemented evidence-based treatments. Likewise, TFD could be a helpful case monitoring tool for clinicians, supervisors, and systems leaders when reviewing intensive-in-home cases.

Associated predictors of functional impairment among adolescents with ADHD-a cross-sectional study

BACKGROUND

Attention-deficit/hyperactivity disorder (ADHD) in adolescence is associated with functional impairment in several domains of life. To enable development of interventions that more effectively target functional impairment in this age group, the associations between clinical characteristics and impairment need to be clarified. The aim of this study was to investigate the associations between ADHD and functional impairment, if they varied by sex, and the potential impact of comorbid psychiatric symptoms on the associations.

METHODS

This was a cross-sectional study including adolescents with ADHD (n = 164) and a reference group of adolescents without ADHD (n = 106). Self-ratings and parental ratings of functional impairment in different life domains were used as outcomes in all analyses. Differences between groups were investigated with comparative analyses. General linear models (GLMs) were used to explore associations between ADHD symptoms and functional impairment in adolescents with ADHD, while adjusting for of comorbid symptoms, sex, and medication.

RESULTS

Adolescents with ADHD displayed higher levels of functional impairment than peers without ADHD, and girls with ADHD rated higher impairment than their male counterparts. The combined ADHD presentation was associated with the highest levels of self-reported impairment, while parental ratings indicated comparable levels of overall impairment across presentations. In the adjusted GLMs, symptoms of inattention were strongly associated with self- and parent-rated impairment in school, but symptoms of hyperactivity/impulsivity were not, whereas symptoms of both inattention and hyperactivity/impulsivity were modestly associated with self-rated impairment with friends. Further, both emotional and conduct problems were associated with impairment in daily life.

CONCLUSIONS

Our results suggest that attention difficulties, in particular, seem to impair academic functioning in adolescents with ADHD, and interventions targeting such difficulties are warranted. In addition, comorbid symptoms need to be assessed and treated, and self-reports of functioning should be included in research and clinical practice involving adolescents.

Self-reported functional impairment in college students: relationship to noncredible reporting, ADHD, psychological disorders, and other psychological factors

INTRODUCTION

Both symptoms and functional impairment should be assessed in college students seeking evaluations for Attention Deficit Hyperactivity Disorder (ADHD). However, impairment is not specific to ADHD. Although it is well documented that self-reported symptoms can be reported noncredibly, there is less research examining credibility of self-reported impairment, and few clinicians rule out alternative causes for impairment.

METHOD

Participants (N = 428) completed self-report measures of functional impairment, sleep, perceived stress, and in an ADHD symptom measure with embedded validity indicators.

RESULTS

Noncredible reporters endorsed greater functional impairment than credible reporters in several domains, but impairment was reported at a high rate even in credible responders (N = 323) in several domains. Participants who reported prior ADHD and participants who reported prior psychiatric diagnoses reported greater impairment and higher rates of clinically significant impairment than those who reported no prior diagnoses. Few differences in reported impairment emerged between those who reported ADHD and psychiatric diagnoses. Sleep and stress accounted for significant variance in impairment, and the ADHD group reported greater impairment than the psychiatric diagnosis and no diagnosis groups after controlling for these variables.

CONCLUSIONS

Results reinforce the importance of considering the validity of, and alternative sources for, self-reported impairment in college students with ADHD concerns.

Overdiagnosis of Attention-Deficit/Hyperactivity Disorder in Children and Adolescents: A Systematic Scoping Review

IMPORTANCE

Reported increases in attention-deficit/hyperactivity disorder (ADHD) diagnoses are accompanied by growing debate about the underlying factors. Although overdiagnosis is often suggested, no comprehensive evaluation of evidence for or against overdiagnosis has ever been undertaken and is urgently needed to enable evidence-based, patient-centered diagnosis and treatment of ADHD in contemporary health services.

OBJECTIVE

To systematically identify, appraise, and synthesize the evidence on overdiagnosis of ADHD in children and adolescents using a published 5-question framework for detecting overdiagnosis in noncancer conditions.

EVIDENCE REVIEW

This systematic scoping review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Extension for Scoping Reviews and Joanna Briggs Methodology, including the PRISMA-ScR Checklist. MEDLINE, Embase, PsychINFO, and the Cochrane Library databases were searched for studies published in English between January 1, 1979, and August 21, 2020. Studies of children and adolescents (aged ≤18 years) with ADHD that focused on overdiagnosis plus studies that could be mapped to 1 or more framework question were included. Two researchers independently reviewed all abstracts and full-text articles, and all included studies were assessed for quality.

FINDINGS

Of the 12 267 potentially relevant studies retrieved, 334 (2.7%) were included. Of the 334 studies, 61 (18.3%) were secondary and 273 (81.7%) were primary research articles. Substantial evidence of a reservoir of ADHD was found in 104 studies, providing a potential for diagnoses to increase (question 1). Evidence that actual ADHD diagnosis had increased was found in 45 studies (question 2). Twenty-five studies showed that these additional cases may be on the milder end of the ADHD spectrum (question 3), and 83 studies showed that pharmacological treatment of ADHD was increasing (question 4). A total of 151 studies reported on outcomes of diagnosis and pharmacological treatment (question 5). However, only 5 studies evaluated the critical issue of benefits and harms among the additional, milder cases. These studies supported a hypothesis of diminishing returns in which the harms may outweigh the benefits for youths with milder symptoms.

CONCLUSIONS AND RELEVANCE

This review found evidence of ADHD overdiagnosis and overtreatment in children and adolescents. Evidence gaps remain and future research is needed, in particular research on the long-term benefits and harms of diagnosing and treating ADHD in youths with milder symptoms; therefore, practitioners should be mindful of these knowledge gaps, especially when identifying these individuals and to ensure safe and equitable practice and policy.

Psychometric properties of the Weiss Functional Impairment Rating Scale parent and self-reports in a Norwegian clinical sample of adolescents treated for ADHD

OBJECTIVE

To analyze the psychometric properties of the Norwegian version of the Weiss Functional Impairment Rating Scale parent and self-reports (WFIRS-P and WFIRS-S) in adolescents with ADHD.

METHODS

102 clinically referred patients, of which 86% were enrolled in an ongoing RCT program (Clinical trials NCT02937142), were diagnosed with ADHD according to the Diagnostic and Statistical Manual of Mental Disorders version IV (DSM-IV). The conceptual framework of the WFIRS-P and the WFIRS-S was evaluated using confirmatory factor analysis (CFA), reliability was estimated using Cronbach's alpha, convergent and divergent validity was assessed using correlations with the Children's Global Assessment Scale (C-GAS) and the ADHD Rating Scale-IV (ADHD-RS-IV).

RESULTS

CFA supported the original factor structure of the questionnaires, both a first-order and a second-order model revealed acceptable model fit. Internal consistency was satisfactory across domains. The parent-adolescent agreement was moderate. The correlations between the C-GAS and the total scores of the WFIRS-P and WFIRS-S were low to moderate (r = -0.29 to -0.38). The ADHD-RS-IV correlated moderately (r = 0.49) with WFIRS-P, the correlation with WFIRS-S was weak (r = 0.28) supporting divergent validity. In multiple regression analyses, the ADHD-RS total score was the strongest predictor of the total score in both the WFIRS questionnaires, with internalizing disorder showing an additional small contribution. Age, gender and full-scale IQ gave no additional contribution in explaining the variance.

CONCLUSIONS

The findings support the use of the Norwegian version of the WFIRS-S and the WFIRS-P in the evaluation of functional impairment in adolescents with ADHD.

The Impact of Persistent Irritability on the Medication Treatment of Paediatric Attention Deficit Hyperactivity Disorder

This study compares the efficacy and tolerability of central nervous system (CNS) stimulants in children with attention deficit hyperactivity disorder (ADHD) with and without prominent irritability (IRR) over the course of 30 months. This is a secondary analysis of a study examining growth patterns in medication naïve children with ADHD subsequently treated with CNS stimulants (predominantly OROS-Methylphenidate, up to 54 mg per day) for 30 months. Participants had to meet full diagnostic criteria for ADHD and been treated with CNS stimulants for under 30 days. Children were classified as IRR if they were rated as pretty much or very much on either of the "often angry" or easily annoyed" items plus "lose temper," items of the Disruptive Behavior Disorders Rating Scale (DBDRS). Structured ratings of ADHD symptoms, impairment, side effects, and symptoms of oppositional defiant disorder (ODD) were collected every 2-12 weeks for the duration of the study. Medication use was measured by pill count and parent report. The IRR group comprised 28% of all participants. The IRR group had significantly higher levels of ADHD and ODD symptoms, impairment, and side effects ratings at baseline. In the IRR group, ODD symptoms, emotional lability, and impairment significantly decreased for participants with higher medication use. Total side effects increased for non-IRR participants with higher medication use. Emotional side effects decreased for IRR participants with higher medication use. Central nervous system stimulants were a tolerable and efficacious treatment in treatment naïve youth with ADHD with irritability. Clinical Trials Registration: NCT01109849.

Do Preschoolers' Neuropsychological Functioning and Hyperactivity/Inattention Predict Social Functioning Trajectories Through Childhood?

OBJECTIVE

This longitudinal study examined whether preschool attention deficit hyperactivity disorder (ADHD) symptoms and neuropsychological functioning predicted trajectories of children's social functioning from age 3 to 4 through 12 years.

METHODS

Three- and four-year-old children (N = 208; 72.6% boys) were evaluated annually through age 12. Parent and teacher Attention Deficit/Hyperactivity Disorder Rating Scale, Fourth Edition responses during the initial evaluation were used to categorize preschoolers as "High" or "Low" risk for ADHD. Children's neuropsychological functioning was assessed using the NEPSY. Teachers' reports of children's social functioning were obtained annually from preschool through age 12 years using the Adaptability, Functional Communication, and Social Skills subscales of the Behavioral Assessment System for Children, Second Edition. Hierarchical linear modeling was used to assess the trajectories of social functioning and determine whether preschoolers' neuropsychological functioning and ADHD risk status predicted social functioning at age 12 years, and/or change in social functioning throughout childhood. All models controlled for baseline socioeconomic status.

RESULTS

High Risk children had significantly lower teacher-rated Adaptability and Social Skills at age 12 years. High Risk children and those with lower Verbal neuropsychological functioning in preschool had lower teacher-rated Functional Communication at 12 years old. Lower preschool Verbal neuropsychological functioning predicted greater positive change in teacher-rated Functional Communication across childhood.

CONCLUSIONS

Early identification of and intervention for children exhibiting ADHD behaviors is critical given the enduring negative impact of these behaviors on social functioning. Screening preschoolers for verbal difficulties is encouraged given their long-term impact on children's ability to clearly express thoughts and feelings and obtain and provide information.

Clarifying ADHD and Sluggish Cognitive Tempo Item Relations with Impairment: A Network Analysis

Despite the pervasive nature of various forms of impairment associated with attention-deficit/hyperactivity disorder (ADHD), the precise nature of their associations with ADHD and related sluggish cognitive tempo (SCT), particularly at the heterogeneous item level, remains ambiguous. Using innovative network analysis techniques, we sought to identify and examine the concurrent validity of ADHD and SCT bridge items (i.e., those demonstrating the most robust relations with various forms of impairment) with respect to Overall, Home-School, and Community-Leisure impairment domains. Parents of a nationally representative sample of 1742 children (50.17% male) aged 6-17 years completed rating scales of ADHD, SCT, and impairment. Assessment of Bridge Expected Influence suggested eight bridge items primarily from impulsive and Task Completion (i.e., overlapping SCT and inattentive) domains that demonstrated relations with impairment in school performance, completing chores at home, interacting with family members, following rules, and playing sports. Sum scores only including bridge items exhibited relations with Overall, Home-School, and Community-Leisure impairment domains comparable to that of sum scores including all items. Bridge impairment areas were generally consistent across "Childhood" (6-11 years) and "Adolescence" (12-17 years). Problems listening and slowness emerged as bridge items in Childhood, whereas difficulties following through on instructions, problems waiting one's turn, and social withdrawal emerged in Adolescence. Given the comparable validity of ADHD- and SCT-related bridge items versus all items, bridge items, together, may be the most efficient indicators of impairment. Further clarification is needed across development to inform personalized assessment and intervention protocols that account for item-level heterogeneity in ADHD, SCT, and impairment phenotypes.

A Commercial Insurance Claims Analysis of Correlates of Behavioral Therapy Use Among Children With ADHD

OBJECTIVE

The study examined factors associated with uptake of behavioral therapy among children with attention-deficit hyperactivity disorder (ADHD).

METHODS

Insurance claims data from 2008-2014 (MarketScan) were reviewed to examine associations between behavioral therapy use and demographic, patient, family, and provider factors. The association between ADHD medication use and future uptake of behavioral therapy was examined with logistic regression adjusted for covariates found to affect behavioral therapy use.

RESULTS

Among 827,396 youths with ADHD, under 50% received any billable behavioral therapy services over the 7 years. ADHD severity, gender, region of residence, assessment year, comorbid behavioral disorders, and behavioral therapy use by siblings were significantly associated with behavioral therapy use (p<0.001). Parent psychopathology and sibling medication use was not. Children prescribed ADHD medication were 2.5 times less likely than those not prescribed medication to use behavioral therapy, even after adjustment for severity of behavioral health symptoms and other covariates (odds ratio [OR]= 0.41, 95% confidence interval [CI]=.40-.41, p<0.001). Effects of medication use were stronger for future uptake of behavioral therapy (OR=0.25, 95% CI =0.24-0.25, p<.001). The impact of medication use on behavioral therapy use was equally strong for children under age 6 and for older children and did not weaken after release of 2011 guidelines recommending behavioral therapy as the initial ADHD treatment for young children.

CONCLUSIONS

Multiple systems, family, patient and provider factors affected behavioral therapy uptake. ADHD medication was a robust and potentially modifiable factor. It may be advisable to engage families in behavioral therapy prior to initiation of ADHD medication.

Inattention, emotion dysregulation and impairment among urban, diverse adults seeking psychological treatment

Emotion dysregulation is commonly reported among adults with Attention-Deficit/Hyperactivity Disorder. This study examined whether inattention and/or hyperactivity/impulsivity directly affect functional impairment, or whether they do so indirectly by decreasing emotion regulation capabilities. An ethnically, racially and socioeconomically diverse sample of clients seeking treatment at a low-fee outpatient mental health clinic were recruited [N = 177, male n = 59, 33.3%, mean (SD) age = 28.54 (8.41) years]. Participants completed measures of inattention, hyperactivity/impulsivity, emotion regulation and impairment at intake. Inattention was more strongly related to emotion regulation and impairment than hyperactivity/impulsivity. Hayes' PROCESS was used to test for significant indirect effects. More severe inattention was associated with less emotional clarity, which in turn was associated with worse Interpersonal Relationship difficulties; more severe inattention was associated with less access to emotion regulation strategies and poorer emotional clarity, which in turn were associated with greater Symptom Distress; and inattention was directly associated with impairment at school and work. In addition to treating inattention, clinicians should focus on emotion regulation deficits. Specifically, working with individuals to improve identification and labeling of emotions, develop strategies to reduce the intensity of their negative emotions, and feel more confident that they have these tools at their disposable may help to reduce impairment.

Honing in on the Social Difficulties Associated With Sluggish Cognitive Tempo in Children: Withdrawal, Peer Ignoring, and Low Engagement

Sluggish cognitive tempo (SCT) symptoms are associated with social difficulties in children, though findings are mixed and many studies have used global measures of social impairment. The present study tested the hypothesis that SCT would be uniquely associated with aspects of social functioning characterized by withdrawal and isolation, whereas attention deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) symptoms would be uniquely associated with aspects of social functioning characterized by inappropriate responding in social situations and active peer exclusion. Participants were 158 children (70% boys) between 7-12 years of age being evaluated for possible ADHD. Both parents and teachers completed measures of SCT, ADHD, ODD, and internalizing (anxiety/depression) symptoms. Parents also completed ratings of social engagement and self-control. Teachers also completed measures assessing asociality and exclusion, as well as peer ignoring and dislike. In regression analyses controlling for demographic characteristics and other psychopathology symptoms, parent-reported SCT symptoms were significantly associated with lower social engagement (e.g., starting conversations, joining activities). Teacher-reported SCT symptoms were significantly associated with greater asociality/withdrawal and ratings of more frequent ignoring by peers, as well as greater exclusion. ODD symptoms and ADHD hyperactive-impulsive symptoms were more consistently associated with other aspects of social behavior, including peer exclusion, being disliked by peers, and poorer self-control during social situations. Findings provide the clearest evidence to date that the social difficulties associated with SCT are primarily due to withdrawal, isolation, and low initiative in social situations. Social skills training interventions may be effective for children displaying elevated SCT symptomatology.

Academic Skills Groups for Middle School Children With ADHD in the Outpatient Mental Health Setting: An Open Trial

OBJECTIVE

To conduct an open trial assessing the initial efficacy of an intervention focusing on increasing skills related to academic performance (planning, organization, studying, and homework behaviors) for middle school children diagnosed with ADHD. The intervention is modeled on evidence-based interventions but designed for administration in the outpatient setting.

METHOD

Parents and their children diagnosed with ADHD attended seven weekly group sessions targeting academic, organizational, and homework skills. Parents completed the Homework Problem Checklist and Impairment Rating Scale pre- and post-treatment.

RESULTS

Following intervention, significant improvements in homework completion and management, as well as reductions in academic impairment and improvements in parent confidence and family relations, were reported.

CONCLUSION

Despite limitations including small sample size and lack of a control group, our results demonstrate initial efficacy of an academic skills intervention designed for use in the outpatient setting with middle school children diagnosed with ADHD on clinically relevant outcome measures.

Is it possible to determine the level of functional impairment that distinguishes the patients with ADHD from those without ADHD?

INTRODUCTION

Functional impairment in attention deficit hyperactivity disorder (ADHD) can occur in many areas such as in family, social activities, and problems related to school and may also persist during adulthood. The Weiss Functional Impairment Rating Scale-Parent Form (WFIRS-P) is designed to measure the functional impairment related to ADHD symptoms. The aim of this study was to determine the level of functional impairment that distinguishes the patients with ADHD who were diagnosed through semi-structured interviews from those without ADHD.

METHOD

This study consists of ADHD patients who were diagnosed through semi-structured interview aged 5-18 years (n = 250) and same age gender-matched healthy controls (n = 250). A receiver operating characteristic (ROC) curve was constructed by calculating the sensitivity and specificity of the scale cut-off values.

RESULTS

An area under the curve (AUC) of 0.974 (95% CI 0.956-0.986) was found in this study. For WFIRS-P subdomains, AUC curves, which range from 0.76 to 0.95, were also having strong power for differentiation between groups. The optimal cut-off value for WFIRS-P using Youden's J Index is 0.32. There is no significant gender and age group differences in AUC for either the total or subdomain scores.

CONCLUSION

Our findings provide that Turkish version of WFIRS-P could be a reliable way of distinguishing the level of functional impairment in ADHD from controls.

Reasons Why Children and Adolescents With Attention-Deficit/Hyperactivity Disorder Stop and Restart Taking Medicine

OBJECTIVE

To describe the prevalence of reasons why children and adolescents stop and restart attention-deficit/hyperactivity disorder (ADHD) medicine and whether functional impairment is present after stopping medicine.

METHODS

We used the prospective longitudinal cohort from the Multimodal Treatment of Study of Children With ADHD. At the 12-year follow-up, when participants were a mean of 21.1 years old, 372 participants (76% male, 64% white) reported ever taking ADHD medicine. Participants reported the age when they last stopped and/or restarted ADHD medicine and also endorsed reasons for stopping and restarting.

RESULTS

Seventy-seven percent (286 of 372) reported stopping medicine for a month or longer at some time during childhood or adolescence. Participants were a mean of 13.3 years old when they last stopped medicine. The most commonly endorsed reasons for stopping medication related to 1) medicine not needed/helping, 2) adverse effects, 3) logistical barriers of getting or taking medication, and 4) social concerns or stigma. Seventeen percent (64 of 372) reported restarting medicine after stopping for a month or longer. Commonly endorsed reasons for restarting related to medicine being needed or medicine helping; and resolution of logistical barriers to getting or taking medicine. For both stopping and restarting, the proportion endorsing some reasons differed by age range, with the overall pattern suggesting that parental involvement in decisions decreased with age. Nearly all participants had impairment at the assessment after stopping, regardless of whether medication was resumed.

CONCLUSIONS

Different reasons for stopping and/or restarting medicine are relevant at different times for different teens. Tailored strategies may help engage adolescents as full partners in their treatment plan.

Proof-of-concept study of an at-home, engaging, digital intervention for pediatric ADHD

OBJECTIVE

Pharmacological and behavioral therapies have limited impact on the distinct neurocognitive impairments associated with ADHD, and existing cognitive training programs have shown limited efficacy. This proof-of-concept study assessed treatment acceptability and explored outcomes for a novel digital treatment targeting cognitive processes implicated in ADHD.

METHOD

Participants included 40 children with ADHD and 40 children without ADHD. Following psychiatric screening, ADHD ratings, and baseline neuropsychological measures, participants completed 28-days of at-home treatment. Neuropsychological assessment was repeated at end-of-study along with treatment satisfaction measures.

RESULTS

Eighty-four percent of treatment sessions were completed and ratings showed strong intervention appeal. Significant improvements were observed on a computerized attention task for the ADHD group and a highly impaired ADHD High Severity subgroup. There was no change for the non-ADHD group. Spatial working memory also improved for the ADHD group and the ADHD High Severity subgroup.

CONCLUSION

Findings provide preliminary support that this treatment may improve attention, working memory, and inhibition in children with ADHD. Future research requires larger-scale randomized controlled trials that also evaluate treatment impact on functional impairments.

Specific Components of Pediatricians' Medication-Related Care Predict Attention-Deficit/Hyperactivity Disorder Symptom Improvement

OBJECTIVE

The development of attention-deficit/hyperactivity disorder (ADHD) care quality measurements is a prerequisite to improving the quality of community-based pediatric care of children with ADHD. Unfortunately, the evidence base for existing ADHD care quality metrics is poor. The objective of this study was to identify which components of ADHD care best predict patient outcomes.

METHOD

Parents of 372 medication-naïve children in grades 1 to 5 presenting to their community-based pediatrician (N = 195) for an ADHD-related concern and who were subsequently prescribed ADHD medication were identified. Parents completed the Vanderbilt ADHD Parent Rating Scale (VAPRS) at the time ADHD was raised as a concern and then approximately 12 months after starting ADHD medication. Each patient's chart was reviewed to measure 12 different components of ADHD care.

RESULTS

Across all children, the mean decrease in VAPRS total symptom score during the first year of treatment was 11.6 (standard deviation 10.1). Of the 12 components of ADHD care, shorter times to first contact and more teacher ratings collected in the first year of treatment significantly predicted greater decreases in patient total symptom scores. Notably, it was timeliness of contacts, defined as office visits, phone calls, or email communication, that predicted more ADHD symptom decreases. Office visits alone, in terms of number or timeliness, did not predict patient outcomes.

CONCLUSION

The magnitude of ADHD symptom decrease that can be achieved with the use of ADHD medications was associated with specific components of ADHD care. Future development and modifications of ADHD quality care metrics should include these ADHD care components.

Targeting Functional Impairments in the Treatment of Children and Adolescents with ADHD

The diagnostic criteria for attention-deficit hyperactivity disorder (ADHD) require both symptoms and impairment to be present. Impairment in functioning is commonly the primary reason for referral, and is also a better predictor of long-term outcomes than ADHD symptoms. And yet, only recently has research begun to examine the impact of ADHD treatments on functional impairment using efficient and psychometrically sound outcome measures. In this article, we identify several noteworthy multidimensional measures of functional impairment (ADHD FX, Barkley Functional Impairment Scale [BFIS], Impairment Rating Scale [IRS], Weiss Functional Impairment Rating Scale [WFIRS]) utilized in recent clinical trials for ADHD, and describe their psychometric properties and clinical utility. We also review existing evidence on the impact of pharmacological and behavioral treatments on different domains of functional impairment in ADHD youth as measured by these specific measures. Further research is needed to evaluate longitudinal effects of ADHD treatments on functional impairment, and the use of these measures in adaptive treatment designs.

Progression of impairment in adolescents with attention-deficit/hyperactivity disorder through the transition out of high school: Contributions of parent involvement and college attendance

Long-term, prospective follow-up studies of children diagnosed with attention-deficit/hyperactivity disorder (ADHD) show that symptoms tend to decline with age, but impairments in daily life functioning often persist into adulthood. We examined the developmental progression of impairments before and after the transition out of high school in relation to parent involvement during adolescence, parent support during adulthood, and college attendance, using 8 waves of data from the prospective 16-year follow-up of the Multimodal Treatment of ADHD (MTA) study. Participants were 548 proband children diagnosed with Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV; American Psychiatric Association, 2000) ADHD Combined Type and 258 age- and sex-matched comparison children (Local Normative Comparison Group; LNCG) randomly sampled from probands' schools. Impairment was assessed consistently by parent report from childhood through adulthood. Results showed that impairment worsens over time both before and after the transition to adulthood for those with ADHD histories, in contrast to non-ADHD peers, whose impairments remained stably low over time. However, impairment stabilized after leaving high school for young adults with ADHD histories who attended college. Involved parenting in adolescence was associated with less impairment overall. Attending college was associated with a stable post-high school trajectory of impairment regardless of parents' involvement during adolescence, but young adults with histories of involved parenting and who attended college were the least impaired overall.

The interplay among temperament, neuropsychological abilities, and global functioning in young hyperactive/inattentive children

Cognition and emotion have been shown to interact and influence psychological functioning. However, to date these interactions have only been examined cross-sectionally among inattentive and/or hyperactive/impulsive children. This study investigated the moderating effects of neuropsychological functioning at age 3-4 years on the relation between negative emotionality at age 3-4 years and global functioning 1 year later, at age 4-5 years. Hyperactive/inattentive (H/I; n = 114) preschoolers entered the study (BL: baseline) and were seen again 1 year later (F1). Children's BL scores on a neuropsychological test (NEPSY) and their temperament as rated by parents (Child Behavior Questionnaire) and teachers (Temperament Assessment Battery for Children-Revised) were obtained, as were clinicians' ratings of their global functioning (Children's Global Assessment Scale) at F1. Hierarchical linear regression analyses revealed that BL temperament variables accounted for significant variance in F1 Global Functioning. Significant interactions indicated that higher Verbal Executive abilities were associated with better child functioning when parent-rated Effortful Control was high, but not when Effortful Control was low. Additionally, high levels of Nonverbal Executive skills were associated with higher child global functioning when both parent- and teacher-rated negative affect was low, but not when negative affect was high.

Impact of a Web-Portal Intervention on Community ADHD Care and Outcomes

BACKGROUND

The quality of care for children with attention-deficit/hyperactivity disorder (ADHD) delivered in community-based pediatric settings is often poor. Interventions have been developed to improve community-based ADHD care but have not demonstrated that better care results in improved patient outcomes. The objective of this study was to determine whether an ADHD quality improvement (QI) intervention for community-based pediatric practices improves patient outcomes.

METHODS

A cluster randomized controlled trial was conducted in which 50 community-based pediatric primary care practices (213 providers) were randomized either to receive a technology-assisted QI intervention or to a control condition. The intervention consisted of 4 training sessions, office flow modification, guided QI, and an ADHD Internet portal to assist with treatment monitoring. ADHD treatment processes and parent- and teacher-rated ADHD symptoms over the first year of treatment were collected for 577 patients.

RESULTS

Intent-to-treat analyses examining outcomes of all children assessed for ADHD were not significant (b = -1.97, P = .08). However, among the 373 children prescribed ADHD medication, there was a significant intervention effect (b = -2.42, P = .04) indicating greater reductions in parent ratings of ADHD symptoms after treatment among patients treated by intervention physicians compared with patients treated at control practices. There were no group differences on teacher ratings of ADHD symptoms. ADHD treatment care around medication was significantly better at intervention practices compared with control practices.

CONCLUSIONS

A technology-assisted QI intervention improved some ADHD care quality and resulted in additional reductions in parent-rated ADHD symptoms among patients prescribed ADHD medications.

Pharmacological treatment of attention-deficit/hyperactivity disorder: assessing outcomes

A substantial body of evidence has supported the efficacy and safety of pharmacological treatment available for attention deficit/hyperactivity disorder (ADHD). There is increasing agreement that the important treatment outcomes for ADHD extend beyond improvement in core symptoms and that a more generic (or global) concept of remission is the overarching goal of treatment. However, there is no consensus on the best definition of remission or on how best to conceptualize and measure broader treatment outcomes. In this article, we provide an overview of the various methods and approaches to measuring treatment outcomes for ADHD with respect to symptoms, impairment, quality of life, adverse events and safety as well as cognition. We will describe the ways that they may be used within routine clinical practice and think ahead about the kinds of studies that are required to move the field forward.
