Patterns and predictors of adolescent engagement in a mindfulness-based social-emotional learning program.

INTRODUCTION: Although mindfulness-based interventions (MBIs) show promise for promoting positive youth development, little is known about student engagement in MBIs. Initial research presents mixed findings in MBI engagement related to participant characteristics, and there is a lack of research examining the influence of context on engagement, despite the critical role context plays in academic engagement. This study examines the contribution of student demographic characteristics and classroom context to MBI engagement. METHODS: Survey engagement data were collected at three time points from 106 ninth grade students (Mage = 14.17 years, 60.4% female, 44.2% Black, 24.8% Hispanic/Latino) who participated in the Be CALM program during the 2021-2022 school year. Latent growth curve modeling was used to examine trajectory of student engagement and assess student and classroom predictors of engagement. RESULTS: There was no overall change in the trajectory of student engagement, although variability was observed across classes. Identifying as Hispanic/Latino was associated with lower engagement (ß = -.25, p = .008), although this did not appear to be related to program experience. Peer connections predicted engagement at the end of the program (ß = .39, p < .001). Post hoc analyses suggested that student engagement may be related to teacher program delivery quality. CONCLUSIONS: Student engagement in MBIs appears related to classroom context more than student characteristics, although further research with larger samples is needed to assess the link between engagement and program outcomes. Findings have implications for designing school-based MBIs and training school staff to deliver them in culturally responsive ways.

Co-Regulation as a Support for Older Youth in the Context of Foster Care: a Scoping Review of the Literature.

Co-regulation is a relatively new theoretical framework for interventions that connects developmental science to adolescent needs and provides strategies that can be applied across contexts. It also has value in shifting the focus of interventions to the role of relationships and interactions with caring adults, as well as supportive environments. This framework may be particularly salient for older youth with foster care experience whose relationships with adults and availability of developmental supports are disrupted. To understand how co-regulation aligns with current understanding of needs and supports for this population, we conducted a scoping review that involved systematically searching four databases, coding and charting relevant information, and actively engaging expert consultants and other stakeholders. Across 46 primarily descriptive articles, co-regulation was discussed most often in relation to relationships, as expected (89% of articles). Despite theoretical and empirical evidence of the benefits of supportive environments and intentional day-to-day interactions in promoting developmental skills and competencies, these two domains of co-regulation were referenced much less (39% and 28%, respectively). Results highlight opportunities for co-regulation supports that can be provided to older youth with foster care experience by caring adults and near-aged peers in a wide range of roles. Notable limitations in the literature were identified in applying co-regulation within the context of employment and career readiness, healthy relationships, and teen parenting. Also under-researched is the role of adult self-regulation skills and co-regulation approaches for youth from diverse backgrounds, including those who identify as LGBTQ or have disabilities. Considerations for practice and future research are provided.

Feasibility of combining biosensor and ecological momentary assessment to measure stress experiences among economically disadvantaged adolescents.

Adolescent stress is complex and impairing. Novel measures are needed to understand stress variability within individuals over time from a physiological as well as a subjective perspective. To test the feasibility of combining ecological momentary assessment (EMA) and wearable biosensors to assess adolescent stress, using an idiographic approach with experience sampling methods. A small sample (n = 23) of predominantly African American, economically disadvantaged adolescents were asked to complete EMA surveys four times per day and wear an armband measuring Heart rate (HR) and skin response for a 2-week period. Descriptive analyses examined number of hours of armband wear, percentage of viable data, and percentage of surveys completed by gender and race. Associations between biosensor data and EMA reports within and across individuals were also examined using hierarchical linear regression. EMA survey completion was good (81%) as was adherence to biosensor protocols, although technological difficulties interfered with collection of HR variability for youth with darker skin tones. Youth reported stressful events in 12.79% of EMA surveys, although 43% reported no negative mood experiences. Convergent validity was supported for detecting between-person (EMA) and within-person (EMA and biosensors) variability in stress across time, although associations across youth were highly variable. Results suggest value for biobehavioral methods in understanding day-to-day stress in adolescents but highlight variability in stress experiences as well as technological limitations, especially for youth of colour.

Meta-analysis of early adolescent self-regulation interventions: Moderation by intervention and outcome type.

INTRODUCTION: Self-regulation has been identified as a highly promising target for interventions promoting broad wellbeing across development; however, there appear to be notable limitations in efficacy for early adolescents in particular. One possible reason is that the emotion regulation needs of youth have not been intentionally targeted in many interventions for this age group. The aim of this study is to advance understanding of how different intervention approaches defined from a clear theoretical model may impact different types of outcomes and with regard to different types of measures. METHODS: We conducted a systematic literature review of four databases using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and identified 33 studies of early adolescents (aged 10-15) using five different intervention approaches that were methodologically rigorous (e.g., randomized controlled trial design with low risk of bias). Studies were conducted predominantly in North America (58%), and Western Europe (30%). RESULTS: A two-level mixed-effects meta-analysis indicated a small but significant overall intervention effect (Hedges g = 0.12). When examined by intervention type, effects were significant only for approaches focusing predominantly on emotion regulation (g = 0.20), which significantly improved behavioral outcomes as well as emotional outcomes. Approaches examining cognitive regulation, parent training, physical activity, and working memory did not differ significantly from zero. Across intervention types, outcomes demonstrated the largest effects for youth report of emotional distress. CONCLUSION: Overall, results suggest that emotion regulation may be a critically important self-regulation mechanism during early adolescence and demonstrates value in the use of applied theoretical frameworks to operationalize intervention approaches and outcomes.

Addressing Barriers to Primary Care Screening and Referral to Prevention for Youth Risky Health Behaviors: Evidence Regarding Potential Cost-Savings and Provider Concerns.

Despite growing evidence and support for co-locating behavioral services in primary care to prevent risky health behaviors, implementation of these services has been limited due to a lack of reimbursement for services and negative perceptions among providers. We investigated potential to overcome these barriers based on new developments in healthcare funding and screening and referral to prevention (SRP) in primary care based on the Consolidated Framework for Implementation Research (CFIR), which could guide future SRP implementation strategies. To investigate the economic need for healthcare-based SRP, we quantified hospital charges to healthcare payors for services arising from adolescent risky behaviors (e.g., substance use, risky sex). Annual North Carolina (NC) hospital charges for these services exceeded $327 M (2019 dollars), suggesting high potential for cost savings if SRP can curb hospital services associated with risky behaviors. To investigate provider barriers and facilitators, we surveyed 151 NC pediatricians and 230 NC family therapists about their attitudes regarding a recently developed well-child visit SRP with family-based prevention. Both sets of professionals reported widespread need for and interest in the SRP but cited barriers of lack of reimbursement, training, and referrals to/from each other. Physicians, but not family therapists, reported concerns with poor patient or parent compliance. Many barriers could be resolved by co-locating family therapists in pediatric clinics to conduct well-child SRP. Our results support further research to develop business models for payor-funded SRP and CFIR-guided research to develop implementation strategies for primary care SRP to prevent adolescent risky health behaviors.

A Qualitative Analysis of Contextual Factors Relevant to Suspected Late-Onset ADHD.

Objective: Recent studies suggest attention-deficit/hyperactivity disorder (ADHD) may emerge post-childhood. We integrate qualitative methods to systematically characterize contextual factors that may (a) delay identification of ADHD in childhood and (b) inform why ADHD symptoms emerge post-childhood. Method: Suspected late-onset ADHD cases from the local normative comparison group of the Multimodal Treatment Study of ADHD completed a qualitative interview (14 young adults and 7 caregivers). Interviews were qualitatively analyzed. Results: We identified five themes. Three themes may attenuate or delay identification of childhood ADHD: external factors (e.g., supportive adults), internal factors (e.g., strong intellectual functioning), and other factors (e.g., dismissive attitudes toward ADHD). Two themes may accompany an increase in ADHD symptoms post-childhood: external factors (e.g., increased external demands) and internal factors (e.g., perceived stress). Conclusion: Clinicians should probe these factors in suspected late-onset cases to address (a) whether, how, and to what extent ADHD was attenuated in childhood and (b) why symptoms emerge post-childhood.

Childhood ADHD and Involvement in Early Pregnancy: Mechanisms of Risk.

Objective: ADHD is associated with risky sexual behavior and early pregnancy, but few studies have examined mechanisms of risk linking childhood ADHD to early pregnancy. The present study utilized data from the Multimodal Treatment Study of ADHD to examine potential mechanisms that may account for the association between childhood ADHD and becoming pregnant or causing a pregnancy by age 18. Method: Participants were 579 children with ADHD and 289 comparison peers followed over 16 years. Results: Relative to the comparison group, those with childhood ADHD were at more than two times increased risk of early pregnancy. Univariately, persistence of ADHD symptoms, delinquency/substance use, and academic performance/achievement during adolescence each mediated the association between childhood ADHD and early pregnancy. When considered together, only delinquency/substance use remained a significant mediator of this relationship. Conclusion: Findings point toward specific targets of intervention for youth with ADHD to prevent early pregnancy.

An Applied Contextual Model for Promoting Self-Regulation Enactment Across Development: Implications for Prevention, Public Health and Future Research.

This theoretical paper presents a public health approach for promoting self-regulation across development that is based in cross-disciplinary theory and research. The self-regulation promotion model includes three key approaches that are each dependent on the relationship that children and youth have with caregivers: teaching self-regulation skills, building supportive environments, and providing co-regulation. This model extends the science of self-regulation insofar as it: (1) focuses on promoting wellbeing (not only reducing risks) across domains of functioning, (2) addresses self-regulation intervention across childhood and through young adulthood, (3) integrates multiple theories and applies them to intervention in meaningful ways, and (4) identifies specific strategies that can be used in natural developmental contexts and that address the social ecological environment as well as the individual child. We describe seven key principles that support the model including a description of self-regulation processes and implications for promoting self-regulation at each developmental stage. We end with broad implications for intervention, highlighting the relevance of the self-regulation promotion model for practitioners, policy makers, and prevention researchers.

Impact of a Neuroscience-Based Health Education Course on High School Students' Health Knowledge, Beliefs, and Behaviors.

PURPOSE: The purpose of this pilot study was to evaluate the potential of an innovative high school neuroscience-based health course for implementation feasibility and impact on student outcomes. METHODS: Thirteen teachers from two high schools participated in this quasi-experimental pilot study including 395 students (202 in the intervention classes and 193 in the comparison classes). Students completed pre/post online surveys assessing their knowledge, beliefs, and behaviors. Our analysis strategy for multi-item measures was to estimate the effects of the intervention on latent change scores in structural equation models. RESULTS: Students in the neuroscience health classes showed a significant increase in neuroscience knowledge as compared to students in the comparison group (difference estimate in proportion correct metric, adjusted for covariates = .04; 95% confidence interval [.01, .06]). However, none of the other primary outcomes showed a significant difference between conditions. Teachers in the intervention group were observed implementing the neuroscience and health components more often than the self-regulation and growth mindset components. Students in the neuroscience group were more likely to mention the importance of caring for their brain and its link to health behaviors. CONCLUSIONS: Findings demonstrate that information about the link between health behaviors and brain functioning can be successfully integrated into a high school health education course, although effects on student health beliefs and behaviors were not observed. Additional development work should focus on clarifying the theoretical mechanisms of change, integrating the neuroscience content with self-regulation and growth mindset, and providing additional professional development for teachers.

Investigating teacher and student effects of the Incredible Years Classroom Management Program in early elementary school.

The present paper reports on the results of a cluster randomized trial of the Incredible Years® Teacher Classroom Management Program (IY-TCM) and its effects on early elementary teachers' management strategies, classroom climate, and students' emotion regulation, attention, and academic competence. IY-TCM was implemented in 11 rural and semi-rural schools with K-2 teachers and a diverse student sample. Outcomes were compared for 45 teachers who participated in five full day training workshops and brief classroom consultation and 46 control teachers; these 91 teachers had a total of 1192 students. A high level of teacher satisfaction was found and specific aspects of the training considered most valuable for early elementary teachers were identified. Hierarchical linear modeling indicated a statistically significant intervention effect on Positive Climate in the classroom (d=0.45) that did not sustain into the next school year. No main effects on student outcomes were observed, although a priori moderator analyses indicated that students with elevated social-behavioral difficulties benefitted with regard to prosocial behavior (d=0.54) and inattention (d=-0.34). Results highlight potential benefits and limitations of a universal teacher training program for elementary students, and suggest strategies for future delivery of the IY-TCM program and areas for future research.

How Substance Users With ADHD Perceive the Relationship Between Substance Use and Emotional Functioning.

OBJECTIVE: Although substance use (SU) is elevated in ADHD and both are associated with disrupted emotional functioning, little is known about how emotions and SU interact in ADHD. We used a mixed qualitative-quantitative approach to explore this relationship. METHOD: Narrative comments were coded for 67 persistent (50 ADHD, 17 local normative comparison group [LNCG]) and 25 desistent (20 ADHD, 5 LNCG) substance users from the Multimodal Treatment Study of Children with ADHD (MTA) adult follow-up (21.7-26.7 years-old). RESULTS: SU persisters perceived SU positively affects emotional states and positive emotional effects outweigh negative effects. No ADHD group effects emerged. Qualitative analysis identified perceptions that cannabis enhanced positive mood for ADHD and LNCG SU persisters, and improved negative mood and ADHD for ADHD SU persisters. CONCLUSION: Perceptions about SU broadly and mood do not differentiate ADHD and non-ADHD SU persisters. However, perceptions that cannabis is therapeutic may inform ADHD-related risk for cannabis use.

Follow-Up of Young Adults With ADHD in the MTA: Design and Methods for Qualitative Interviews.

OBJECTIVE: Qualitative interviews with 183 young adults (YA) in the follow-up of the Multimodal Treatment Study of Children With and Without ADHD (MTA) provide rich information on beliefs and expectations regarding ADHD, life's turning points, medication use, and substance use (SU). METHOD: Participants from four MTA sites were sampled to include those with persistent and atypically high SU, and a local normative comparison group (LNCG). Respondents were encouraged to "tell their story" about their lives, using a semistructured conversational interview format. RESULTS: Interviews were reliably coded for interview topics. ADHD youth more often desisted from SU because of seeing others going down wrong paths due to SU. Narratives revealed very diverse accounts and explanations for SU-ADHD influences. CONCLUSION: Qualitative methods captured the perspectives of YAs regarding using substances. This information is essential for improving resilience models in drug prevention and treatment programs and for treatment development for this at-risk population.

Young adult outcomes in the follow-up of the multimodal treatment study of attention-deficit/hyperactivity disorder: symptom persistence, source discrepancy, and height suppression.

BACKGROUND: The Multimodal Treatment Study (MTA) began as a 14-month randomized clinical trial of behavioral and pharmacological treatments of 579 children (7-10 years of age) diagnosed with attention-deficit/hyperactivity disorder (ADHD)-combined type. It transitioned into an observational long-term follow-up of 515 cases consented for continuation and 289 classmates (258 without ADHD) added as a local normative comparison group (LNCG), with assessments 2-16 years after baseline. METHODS: Primary (symptom severity) and secondary (adult height) outcomes in adulthood were specified. Treatment was monitored to age 18, and naturalistic subgroups were formed based on three patterns of long-term use of stimulant medication (Consistent, Inconsistent, and Negligible). For the follow-up, hypothesis-generating analyses were performed on outcomes in early adulthood (at 25 years of age). Planned comparisons were used to estimate ADHD-LNCG differences reflecting persistence of symptoms and naturalistic subgroup differences reflecting benefit (symptom reduction) and cost (height suppression) associated with extended use of medication. RESULTS: For ratings of symptom severity, the ADHD-LNCG comparison was statistically significant for the parent/self-report average (0.51 ± 0.04, p < .0001, d = 1.11), documenting symptom persistence, and for the parent/self-report difference (0.21 ± 0.04, p < .0001, d = .60), documenting source discrepancy, but the comparisons of naturalistic subgroups reflecting medication effects were not significant. For adult height, the ADHD group was 1.29 ± 0.55 cm shorter than the LNCG (p < .01, d = .21), and the comparisons of the naturalistic subgroups were significant: the treated group with the Consistent or Inconsistent pattern was 2.55 ± 0.73 cm shorter than the subgroup with the Negligible pattern (p < .0005, d = .42), and within the treated group, the subgroup with the Consistent pattern was 2.36 ± 1.13 cm shorter than the subgroup with the Inconsistent pattern (p < .04, d = .38). CONCLUSIONS: In the MTA follow-up into adulthood, the ADHD group showed symptom persistence compared to local norms from the LNCG. Within naturalistic subgroups of ADHD cases, extended use of medication was associated with suppression of adult height but not with reduction of symptom severity.

Meaningful Effect Sizes, Intraclass Correlations, and Proportions of Variance Explained by Covariates for Planning Two- and Three-Level Cluster Randomized Trials of Social and Behavioral Outcomes.

BACKGROUND: There is a need for greater guidance regarding design parameters and empirical benchmarks for social and behavioral outcomes to inform assumptions in the design and interpretation of cluster randomized trials (CRTs). OBJECTIVES: We calculated the empirical reference values on critical research design parameters associated with statistical power for children's social and behavioral outcomes, including effect sizes, intraclass correlations (ICCs), and proportions of variance explained by a covariate at different levels (R 2). SUBJECTS: Children from kindergarten to Grade 5 in the samples from four large CRTs evaluating the effectiveness of two classroom- and two school-level preventive interventions. MEASURES: Teacher ratings of students' social and behavioral outcomes using the Teacher Observation of Classroom Adaptation-Checklist and the Social Competence Scale-Teacher. RESEARCH DESIGN: Two types of effect size benchmarks were calculated: (1) normative expectations for change and (2) policy-relevant demographic performance gaps. The ICCs and R 2 were calculated using two-level hierarchical linear modeling (HLM), where students are nested within schools, and three-level HLM, where students were nested within classrooms, and classrooms were nested within schools. RESULTS AND CONCLUSIONS: Comprehensive tables of benchmarks and ICC values are provided to inform prevention researchers in interpreting the effect size of interventions and conduct power analyses for designing CRTs of children's social and behavioral outcomes. The discussion also provides a demonstration for how to use the parameter reference values provided in this article to calculate the sample size for two- and three-level CRTs 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.

Prevalence and Characteristics of School Services for High School Students with Attention-Deficit/Hyperactivity Disorder.

This study examines the prevalence and characteristics of services reported by school staff for 543 high school students participating in the 8 year follow-up of the multi-site Multimodal Treatment study of ADHD (MTA). Overall, 51.6% of students with a history of attention-deficit/hyperactivity disorder (ADHD) were receiving services through an Individualized Educational Plan (IEP) or a 504 plan, a rate higher than expected for this age group. Less than 5% of these had 504 plans; 35.5% attended special education classes. Very few services (except tutoring) were provided outside of an IEP or 504 plan. Almost all students with services received some type of academic intervention, whereas only half received any behavioral support or learning strategy. Less than one-fourth of interventions appear to be evidence-based. Students receiving services showed greater academic and behavioral needs than those not receiving services. Services varied based upon type of school, with the greatest number of interventions provided to students attending schools that only serve those with disabilities. Original MTA treatment randomization was unrelated to services, but cumulative stimulant medication and greater severity predicted more service receipt. Results highlight a need for accommodations with greater evidence of efficacy and for increased services for students who develop academic difficulties in high school.

Methylphenidate in children with ADHD with or without learning disability.

OBJECTIVE: To explore treatment response to Osmotic Release Oral System(®) (OROS) methylphenidate in children with ADHD with and without comorbid learning disability (LD). METHOD: Data were analyzed from two 6-week, double-blind, randomized, placebo-controlled, crossover studies evaluating individually determined doses of OROS methylphenidate versus placebo in 135 children (ages 9 to 12 years) with ADHD with or without an LD in reading, math, or both. The sample was demographically diverse, with 31% females and more than 40% minority, predominantly African American and Hispanic. On two laboratory school days, participants received either OROS methylphenidate or placebo and were given a battery of cognitive and behavioral tests. RESULTS: Treatment with OROS methylphenidate led to improvement in ADHD Rating Scale scores for participants with or without comorbid LD. Both groups performed better during treatment with OROS methylphenidate than placebo on measures of cognitive skills (i.e., Test of Variables of Attention, Finger Windows Backwards), academically related tasks (i.e., Dynamic Indicators of Basic Early Literacy Skills, Test of Handwriting Skills-Revised, Permanent Product Math Test), and observed classroom behavior (i.e., Swanson, Kotkin, Alger, M-Flynn, and Pelham Scale). CONCLUSION: In children with ADHD with or without comorbid LD, behavior and performance improved during treatment with OROS methylphenidate.

The Preschool Attention-Deficit/Hyperactivity Disorder Treatment Study (PATS) 6-year follow-up.

OBJECTIVE: To describe the clinical course of attention-deficit/hyperactivity disorder (ADHD) symptom severity and diagnosis from ages 3 to 5 up to 9 to 12 years during a 6-year follow-up after the original Preschool ADHD Treatment Study (PATS). METHOD: A total of 207 participants (75% male) from the original PATS, assessed at baseline (mean age, 4.4 years, when all met criteria for ADHD) and 3 months later (before medication treatment), were re-evaluated in three follow-up assessment visits (year 3, mean age 7.4 years; year 4, 8.3 years; and year 6, 10.4 years). Parents and teachers rated symptom severity, and clinicians established psychiatric diagnoses. Analyses examined longitudinal changes in symptom severity and ADHD diagnosis. RESULTS: Parent- and teacher-rated symptom severity decreased from baseline to year 3 but remained relatively stable and in the moderate-to-severe clinical range through year 6. Girls showed generally steeper decreases in symptom T-scores. At year 6, 89% (160/180) of remaining participants met ADHD symptom and impairment diagnostic criteria. Comorbidity of oppositional defiant disorder and/or conduct disorder was associated with a 30% higher risk of having an ADHD diagnosis at year 6 in the multiple logistic model. Medication status during follow-up, on versus off, did not predict symptom severity change from year 3 to year 6 after adjustment for other variables. CONCLUSIONS: ADHD in preschoolers is a relatively stable diagnosis over a 6-year period. The course is generally chronic, with high symptom severity and impairment, in very young children with moderate-to-severe ADHD, despite treatment with medication. Development of more effective ADHD intervention strategies is needed for this age group.

Remediating organizational functioning in children with ADHD: immediate and long-term effects from a randomized controlled trial.

OBJECTIVE: The study compared the efficacy of 2 behavioral interventions to ameliorate organization, time management, and planning (OTMP) difficulties in 3rd- to 5th-grade children with attention-deficit/hyperactivity disorder (ADHD). METHOD: In a dual-site randomized controlled trial, 158 children were assigned to organizational skills training (OST; N = 64); PATHKO, a performance-based intervention that precluded skills training (N = 61); or a wait-list control (WL, N = 33). Treatments were 20 individual clinic-based sessions over 10-12 weeks. OST involved skills building provided primarily to the child. PATHKO trained parents and teachers to reinforce children contingently for meeting end-point target goals. Primary outcomes were the Children's Organizational Skills Scales (COSS-Parent, COSS-Teacher). Other relevant functional outcomes were assessed. Percentage of participants no longer meeting inclusion criteria for OTMP impairments informed on clinical significance. Assessments occurred at post-treatment, 1-month post-treatment, and twice in the following school year. RESULTS: OST was superior to WL on the COSS-P (Cohen's d = 2.77; p < .0001), COSS-T (d = 1.18; p < .0001), children's COSS self-ratings, academic performance and proficiency, homework, and family functioning. OST was significantly better than PATHKO only on the COSS-P (d = 0.63; p < .005). PATHKO was superior to WL on most outcomes but not on academic proficiency. Sixty percent of OST and PATHKO participants versus 3% of controls no longer met OTMP inclusion criteria. Significant maintenance effects were found for both treatments. CONCLUSIONS: Two distinct treatments targeting OTMP problems in children with ADHD generated robust, sustained functional improvements. The interventions show promise of clinical utility in children with ADHD and organizational deficits.

Effects of OROS methylphenidate on academic, behavioral, and cognitive tasks in children 9 to 12 years of age with attention-deficit/hyperactivity disorder.

OBJECTIVE: To assess effects of OROS methylphenidate on cognitive and academic tasks in 9 to 12 year olds with attention-deficit/hyperactivity disorder (ADHD). METHODS: A double-blind, within-subject, crossover design was used to compare OROS methylphenidate with placebo in a laboratory classroom setting on several cognitive and academic tasks for 68 children who met randomization criteria. RESULTS: Performance on the following measures was significantly better when children received individually optimized OROS methylphenidate than placebo: math fluency and accuracy measured by the Permanent Product Math Test, ADHD symptoms observed in the laboratory setting, computerized indices of attention and impulsivity as measured by the Test of Variables of Attention (TOVA), and visual-spatial working memory (Finger Windows Backwards). Study medication was well tolerated; adverse events were generally consistent with previous reports. CONCLUSIONS: OROS methylphenidate improves performance on measures of attention and vigilance, behavior, and working memory in a laboratory school setting in 9 to 12 year olds with ADHD.
