RESUMO

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder characterized by inattention and/or impulsivity/hyperactivity. ADHD, especially when persisting into adulthood, often includes emotional dysregulation, such as affect lability; however, the neural correlates of emotionality in adults with heterogeneous ADHD symptom persistence remain unclear. METHODS: The present study sought to determine shared and distinct functional neuroanatomical profiles of neural circuitry during emotional interference resistance using the emotional face n-back task in adult participants with persisting (n = 47), desisting (n = 93), or no (n = 42) childhood ADHD symptoms while undergoing functional magnetic resonance imaging. RESULTS: Participants without any lifetime ADHD diagnosis performed significantly better (faster and more accurately) than participants with ADHD diagnoses on trials with high cognitive loads (2-back) that included task-irrelevant emotional distractors, tapping into executive functioning and emotion regulatory processes. In participants with persisting ADHD symptoms, more severe emotional symptoms were related to worse task performance. Heightened dorsolateral and ventrolateral prefrontal cortex activation was associated with more accurate and faster performance on 2-back emotional faces trials, respectively. Reduced activation was associated with greater affect lability in adults with persisting ADHD, and dorsolateral prefrontal cortex activation mediated the relationship between affect lability and task accuracy. CONCLUSIONS: These findings suggest that alterations in dorsolateral prefrontal cortex function associated with greater interference in cognitive processes from emotion could represent a marker of risk for problems with emotional dysregulation in individuals with persisting ADHD and thus represent a potential therapeutic target for those with greater emotional symptoms of ADHD.

RESUMO

OBJECTIVE: Parent history of alcohol-related problems and antisocial behaviors contribute to adolescent alcohol use and are associated with offspring attention-deficit/hyperactivity disorder (ADHD). Youth with ADHD may be susceptible to intergenerational transmission of alcohol-related cognitions, which may model drinking motives that enhance risk for adolescent alcohol use. We examined whether childhood ADHD and parent history of alcohol use disorder, with or without antisociality, were associated with adolescents' perceptions of their parents' drinking motives and whether these perceptions predicted their alcohol use behaviors. METHOD: Adolescents (N = 199; 56% with ADHD; Mage = 15.73) completed the Drinking Motives Questionnaire regarding perceptions of their parents' drinking motives. Participants subsequently reported their past-year alcohol use behaviors (Mage = 16.95). Parents reported their history of alcohol-related problems and antisocial symptoms. Covariates included adolescent gender (7% girls), race (9% self-identified Black), and parental education and marital status. RESULTS: Perceived parent drinking motives were highest for social and lowest for conformity motives, consistent with adult self-reports in the literature. Parent alcohol use and antisociality history predicted perceptions of parent drinking motives, and child ADHD only predicted perceptions of parent social drinking motives. Perceived parent drinking motives predicted adolescent alcohol use, but only among youth without ADHD. CONCLUSION: Findings reflect the potential importance of assessing adolescent perceptions of parent drinking motives for adolescents without ADHD and a possible need for supporting parents in communicating about their own alcohol use. Future research should consider alternative strategies (e.g., assessing implicit cognitions) for studying the link between alcohol-related cognitions and behaviors for adolescents with ADHD.

RESUMO

Behavioral treatment, stimulants, and their combination are the recommended treatments for childhood attention-deficit/hyperactivity disorder (ADHD). The current study utilizes within-subjects manipulations of multiple doses of methylphenidate (placebo, 0.15, 0.30, and 0.60 mg/kg/dose t.i.d.) and intensities of behavioral modification (no, low, and high intensity) in the summer treatment program (STP) and home settings. Outcomes are evaluated in the home setting. Participants were 153 children (ages 5-12) diagnosed with ADHD. In alignment with experimental conditions implemented during the STP day, parents implemented behavioral modification levels in three-week intervals, child medication status varied daily, and the orders were randomized. Parents provided daily reports of child behavior, impairment, and symptoms and self-reported parenting stress and self-efficacy. At the end of the study, parents reported treatment preferences. Stimulant medication led to significant improvements across all outcome variables with higher doses resulting in greater improvement. Behavioral treatment significantly improved child individualized goal attainment, symptoms, and impairment in the home setting and parenting stress and self-efficacy. Effect sizes indicate that behavioral treatment combined with a low-medium dose (0.15 or 0.30 mg/kg/dose) of medication results in equivalent or superior outcomes compared to a higher dose (0.60 mg/kg/dose) of medication alone. This pattern was seen across outcomes. Parents overwhelmingly reported preferring treatment with a behavioral component as a first-choice treatment (99%). Results underscore the need to consider dosing as well as parent preference when utilizing combined treatment approaches. This study provides further evidence that combining behavioral treatment and stimulant medication may reduce the stimulant dose needed for beneficial effects.

RESUMO

Attention-deficit/hyperactivity disorder (ADHD) is a chronic neurodevelopmental disorder defined by pervasive symptoms of inattention, hyperactivity, and impulsivity. Furthermore, children with ADHD show marked deficits in executive functioning (EF) such as attention, effortful control, and behavior, and are more likely to have poor self-regulatory skills. Current evidence-based interventions for children with ADHD include behavioral treatment (BT), psychopharmacological treatment, and their combination. Many other interventions are often used conjunction with or in lieu of evidence-based treatments for ADHD. One such example is the use of mindfulness-based interventions which have been shown to improve attention, reduce maladaptive behaviors, and increase self-regulatory abilities among children in general education settings. The current study is the first to evaluate the effect of mindfulness intervention in combination with BT on behavior, task-based executive functioning (EF), and mindful awareness in elementary-aged children with ADHD (N = 58). The study took place in a controlled analogue summer program setting (STP) in which children were randomized to receive either the mindfulness intervention in conjunction with BT or to a BT active control condition. Children completed a variety of EF cognitive tasks at baseline and post-treatment. Child behavioral responses were measured as teacher and staff-recorded frequencies of observed behavior. In addition, parent-reported and child self-reported measures on mindful awareness were collected. Overall, there were no beneficial incremental effects of mindfulness when used in combination with intensive BT with regard to observed child behavior, attention and inhibitory control, or mindful awareness.

RESUMO

Childhood attention-deficit/hyperactivity disorder (ADHD) is associated with substantial burden to caregiver quality of life (QoL). However, a paucity of work has focused on quantifying QoL among caregivers of adolescents with a history of ADHD. The purpose of the current study was (1) to quantify maternal QoL in a sample of mothers of adolescents with and without childhood ADHD; and (2) to examine predictors (i.e., parent and child characteristics and behavior) associated with maternal QoL. Participants included mothers of adolescents with (N = 110) and without ADHD (N = 90) ranging in age from 13 to 18 (M = 16.09, 92% male). The Quality Adjusted Life-Year (QALY) was used to calculate maternal QoL using two health domains (i.e., anxiety/depression and disruption in daily activities) commonly impacted by raising youth with ADHD. QALYs are valued monetarily to estimate disease burden. Mothers of adolescents with childhood ADHD experienced significantly worse QoL relative to mothers in the comparison group. Maternal depression, as well as adolescent age, ADHD status, and discipline problems significantly predicted lower levels of maternal QALY health status index, with ADHD being the strongest predictor. This is equal to a reduction in 1.96 QALYs when summed over the course of a child's lifetime and is associated with a loss of $98,000 to $196,000. Results of the investigation help to further elucidate the health impacts incurred by families of adolescents with ADHD and have important public health implications. Further, parental QoL should be considered when conceptualizing the financial and negative health impact of ADHD.

RESUMO

OBJECTIVE: Evaluate whether stimulant medication improves acquisition of academic material in children with attention deficit hyperactivity disorder (ADHD) receiving small-group, content-area instruction in a classroom setting. METHOD: Participants were 173 children between the ages of 7 and 12 years old (77% male, 86% Hispanic) who met Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for ADHD and were participating in a therapeutic summer camp. The design was a triple-masked, within-subject, AB/BA crossover trial. Children completed two consecutive phases of daily, 25-min instruction in both (a) subject-area content (science, social studies) and (b) vocabulary. Each phase was a standard instructional unit lasting for 3 weeks. Teachers and aides taught the material to small groups in a summer classroom setting. Each child was randomized to be medicated with daily osmotic-release oral system methylphenidate (OROS-MPH) during either the first or second of the instructional phases, receiving placebo during the other. RESULTS: Medication had large, salutary, statistically significant effects on children's academic seatwork productivity and classroom behavior on every single day of the instructional period. However, there was no detectable effect of medication on learning the material taught during instruction: Children learned the same amount of subject-area and vocabulary content whether they were taking OROS-MPH or placebo during the instructional period. CONCLUSIONS: Acute effects of OROS-MPH on daily academic seatwork productivity and classroom behavior did not translate into improved learning of new academic material taught via small-group, evidence-based instruction.

RESUMO

The conceptual overlap between mind-wandering and attention-deficit/hyperactivity disorder (ADHD)-related impairments is considerable, yet little experimental research examining this overlap among children is available. The current study aims to experimentally manipulate mind-wandering among children with and without ADHD and examine effects on task performance. Participants were 59 children with ADHD and 55 age-matched controls. Participants completed a novel mind-wandering sustained attention to response task (SART) that included non-self-referential and self-referential stimuli to experimentally increase self-referential mind-wandering, reflected by increases in reaction time variability (RTV) following self-referential stimuli. The ADHD group participated in a classroom study with analogue conditions aimed at encouraging self-referential future-oriented thinking (free play/movie before and after class work) compared to a control condition (newscast) and a cross-over methylphenidate trial. The significant interaction between ADHD status and self-referential stimuli on SART performance indicated that self-referential stimuli led to greater RTV among children with ADHD (within-subject d = 1.29) but not among controls. Methylphenidate significantly reduced RTV among youth with ADHD across self-referential (d = 1.07) and non-self-referential conditions (d = 0.72). In the ADHD classroom study, the significant interaction between mind-wandering condition and methylphenidate indicated that methylphenidate led to higher work completion (ds > 5.00), and the free-play mind-wandering condition had more consistent detrimental effects on productivity (ds ≥ 1.25) than the movie mind-wandering condition. This study is the first to manipulate mind-wandering and assess effects among children with ADHD using a behavioral task. Results provide evidence that children with ADHD are uniquely susceptible to mind-wandering interference.

RESUMO

Individuals with Attention-Deficit Hyperactivity Disorder (ADHD) consistently exhibit a stronger preference for immediate rewards than for larger rewards available following a delay on tasks measuring choice impulsivity (CI). Despite this, however, there remains a dearth of studies examining the impact of stimulant treatment on CI as well as associated higher order (e.g., working memory [WM]) and perceptual (e.g., time perception) cognitive processes. The present study examines the effect of osmotic release oral system methylphenidate (OROS-MPH) on CI, WM and time perception processes as well as the relation among these processes before and after taking a regimen of OROS-MPH. Thirty-five children (aged 7-12 years) with a diagnosis of ADHD participating in a concurrent stimulant medication study were recruited to complete computerized assessments of CI, WM, and time perception. Children completed the assessments after administration of a placebo as well as their lowest effective dose of OROS-MPH following a 2-week titration period. The results from one-sample t-tests indicated that OROS-MPH improves both CI and WM in youth with ADHD but does not impact time perception. Further, results revealed no significant association among the various indices of cognitive performance while taking placebo or OROS-MPH. Overall, the findings suggest that while OROS-MPH improves both CI and WM in youth with ADHD, improvements in CI as a result of OROS-MPH are unlikely to be associated with the improvements in WM given the lack of association among the two. Future studies should consider alternate cognitive, emotional, and motivational mechanisms that may account for the impact of OROS-MPH on CI.

RESUMO

OBJECTIVE: To test whether smoking-specific risk factors in early adulthood mediate prediction to daily smoking from childhood ADHD. METHODS: Participants were 237 with and 164 without childhood ADHD. A smoking risk profile score comprising smoking-specific factors measured between ages 18 to 25 (e.g., craving severity) and age of initiation was tested as mediator of the association between childhood ADHD and age 29 daily smoking. RESULTS: Childhood ADHD predicted age 29 smoking (ß = -.15, p = .019), 35% of ADHD versus 17% of nonADHD, and the profile score (ß = -.07, p = .004), which in turn mediated prediction to age 29 daily smoking (ß = -.03; p = .007). When tested individually, three profile variables (# cigarettes/day, difficulty concentrating during abstinence, and nicotine dependence) were significant mediators (ps = 0.005-0.038), above and beyond early adult smoking, ADHD persistence, and delinquency. CONCLUSIONS: These behavioral smoking characteristics help explain later daily cigarette smoking for adults with ADHD histories and may need to be targeted in intervention.

RESUMO

OBJECTIVE: The General Life Functioning Scale (GLF) was developed to provide a complementary alternative to existing measures of impairment. We examined the psychometric properties of the GLF-Parent version (GLF-P), given the known value of informant ratings. METHODS: The GLF-P was administered to parents of adults with attention-deficit/hyperactivity disorder (ADHD) diagnosed in childhood and a nonADHD comparison group in the Pittsburgh ADHD Longitudinal Study. GLF-P ratings described 334 participants (ADHD = 186; comparison = 148) rated at age 25 (Mage = 24.80 years, SDage = 0.46, range = 24-26) and 401 participants (ADHD = 237; comparison = 164) rated at age 30 (Mage = 29.30, SDage = 0.64, range = 28-33). Exploratory (EFA) and confirmatory (CFA) factor analyses were used. RESULTS: EFAs suggested and CFAs confirmed a five-factor solution. We found measurement invariance across diagnostic and age groups, satisfactory internal consistency, construct validity, and known-group validity. CONCLUSION: Psychometric results suggest the GLF-P as a helpful adjunctive measure of functioning. Further research is needed to determine the utility of the GLF across diverse settings.

RESUMO

BACKGROUND: Although individuals with histories of childhood attention-deficit/hyperactivity disorder (ADHD) report more alcohol-related problems in adulthood than those without ADHD, it is unknown whether there are group differences in certain types of alcohol problems. We tested whether the nature of alcohol problems differed for individuals with and without childhood ADHD, as well as adulthood-persistent ADHD, to facilitate a personalized medicine approach for alcohol problems in this high-risk group. METHODS: Data were drawn from a prospective, observational study. Children diagnosed with ADHD and demographically similar individuals without childhood ADHD were followed prospectively through young adulthood (N = 453; 87.6% male). ADHD symptom persistence was assessed using self-reports and parent reports. Alcohol problems and heavy drinking were assessed repeatedly from 18-30 years old to construct lifetime measures. RESULTS: Full-sample confirmatory factor analyses identified 5 alcohol problem "types:" interpersonal problems/risky behaviors, occupational/academic impairment, impaired control/treatment seeking, tolerance/withdrawal, and drinking to blackout. Latent class analyses of items within each type yielded the best fit for 3-class solutions for all sets of items except blackout drinking, for which 2 classes emerged. Children with ADHD were more likely than those without ADHD to belong to high-risk latent classes for interpersonal problems/risky behaviors, occupational/academic problems, and impaired control (the high-risk class that indexed treatment-seeking behavior). These effects were driven by individuals whose ADHD symptoms persisted into adulthood. Few group differences emerged for tolerance/withdrawal and blackout drinking, except that individuals with only childhood ADHD (no persistence) were more likely to belong to the low-risk groups than those with adulthood-persistent ADHD and without ADHD. CONCLUSIONS: Individuals with ADHD histories whose symptoms persist into adulthood may be more likely to experience socially oriented alcohol problems and impaired control/treatment seeking than individuals without an ADHD history and those with childhood ADHD only. Tailored alcohol prevention and treatment programs may benefit this high-risk population.

RESUMO

The relation between sustained attention in the laboratory and behaviors exhibited in naturalistic settings among children with Attention Deficit/Hyperactivity Disorder (ADHD) remains unclear. Additionally, research on stimulant medication effects in these areas and their association with one another remains scarce. Twenty-one children with ADHD and 21 children without ADHD completed a novel continuous performance test (CPT) involving high cognitive demands (e.g., visual search). Participants with ADHD also attended a Summer Treatment Program and received three doses of stimulant medication (placebo, low, and high). Their behavior in classroom and peer settings was observed and recorded, and they completed the CPT in each medication condition. The CPT measures of bias and sensitivity were used in analyses. Results indicated that children with ADHD had impaired overall performance and worse bias during the second half of the task compared to controls. Methylphenidate improved both naturalistic behavior and overall CPT performance but did not specifically improve the sustained attention deficit. Despite improvements in overall CPT performance, medication-related improvement in CPT performance did not mediate medication-related improvement in observed behavior in classroom or recreational settings. As such, our findings suggest that although children with ADHD do demonstrate a sustained attention deficit, salutary psychostimulant effects on CPT performance are not indicative of, or causally linked to, psychostimulant effects on presenting problems in naturalistic settings.

RESUMO

Variability in working memory (WM) task selection likely contributes to heterogeneity in effect size estimates of deficiencies in youth with attention-deficit/hyperactivity disorder (ADHD). This has resulted in the development of brief, easy to administer assessments such as the NIH List Sorting Working Memory (LSWM) task from the NIH Cognitive Toolbox in hopes of standardizing measurement of this construct. Unfortunately, substantial questions persist regarding the specific constructs being evaluated by this task (e.g., visuospatial [VS] or phonological [PH] WM) as well as the ability of this task to detect WM deficits in previously identified impaired groups (e.g., ADHD). The current study examines the extent to which the LSWM task is associated with VS and PHWM performance as well as symptoms of ADHD. Additionally, we examined the magnitude of differences between ADHD and Typically Developing (TD) youth on this task relative to empirically derived WM tasks utilized in the past. Forty-six children (25 ADHD, 21 TD) completed multiple WM tasks. The LSWM task was moderately associated with PHWM and demonstrated relatively weaker associations with VSWM. Symptoms of inattention and hyperactivity/impulsivity were unrelated to the LSWM task; whereas tasks assessing PH and VSWM were moderately associated with inattention and weakly associated with hyperactivity (VSWM only). No significant between-group differences in performance emerged on the LSWM task; however, significant large-magnitude group differences were observed on both the PH and VSWM tasks. These findings suggest that the LSWM task may lack the ability to detect WM difficulties in youth with ADHD.

RESUMO

BACKGROUND: ADHD poses risk for problematic alcohol use through adulthood. Perceived peer alcohol use, one of the strongest correlates of individuals' own alcohol use, is especially salient for adolescents with ADHD. The extent to which this risk extends into young adulthood is unknown, as well as how change in these constructs is associated throughout young adulthood. METHODS: In the Pittsburgh ADHD Longitudinal Study, 358 individuals with childhood-diagnosed ADHD and 239 without were prospectively followed from ages 18 to 29. Piecewise, bivariate longitudinal growth modeling was used to examine the change in both peer alcohol use and individuals' heavy drinking (binge-drinking frequency), their between-person associations, and differences by ADHD group. The addition of structured residuals probed within-person year-to-year change in peer and personal alcohol use and their prospective associations. RESULTS: Perceived peer alcohol use and individuals' heavy drinking frequencies changed together over time concurrently-from ages 18 to 21 (piece 1) and 21 to 29 (piece 2). Prospectively, individuals who increased the most in heavy drinking from ages 18 to 21 reported more friends using alcohol at age 29, regardless of ADHD history. Within-person increases in personal alcohol use likewise predicted increased perceived peer use the subsequent year within each age group (piece), regardless of ADHD history. However, while decreasing perceived peer use from ages 21 to 29 was related to more frequent heavy drinking at age 29 for those without ADHD, increasing perceived peer use from ages 18 to 21 predicted more frequent heavy drinking at age 29 for those with ADHD. CONCLUSIONS: Young adult heavy drinking changes in tandem with perceived peer alcohol use across individuals and predicts selection of alcohol-using peers from year to year within individuals, further into adulthood than previously documented. Findings suggest the centrality of relationships with alcohol-consuming friends in relation to one's heavy drinking, especially for young adults with ADHD histories, through the twenties.

RESUMO

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) symptoms persist into adulthood and are associated with functional impairments. Neuroimaging studies of reward-modulated inhibitory control can identify potential objective markers of impairment and may deepen our understanding of why probands engage in costly behaviors leading to adverse outcomes. The study aimed to identify reward-modulated inhibitory control neural circuitries, their association with ADHD symptoms, and real-world implications of a decreased capacity to engage in reward-modulated inhibitory control. METHODS: A total of 106 adults (90% male) with rigorous childhood diagnoses of ADHD were scanned with functional magnetic resonance imaging during the Monetary Incentive Go/NoGo task. Adulthood symptoms of inattention and hyperactivity/impulsivity based on self- and informant report were assessed. The number of lifetime attempts taken to quit smoking were also assessed as an exemplar real-world outcome. RESULTS: Hyperactivity/impulsivity was negatively associated with activation in the pallidum and primary motor cortex when inhibiting a previously rewarded Go stimulus that yielded a small immediate reward in order to obtain a larger reward later on. Reduced recruitment of the pallidal-thalamic-motor circuit mediated the negative association between hyperactivity/impulsivity and reward-modulated inhibitory control accuracy. Reduced pallidum activation, in response to reward-modulated inhibitory control, was also associated with more attempts made to successfully quit smoking. CONCLUSIONS: Probands with persistent hyperactivity/impulsivity symptoms have alterations in brain regions that calculate the value of inhibiting an action that yields an immediate reward in order to obtain delayed larger rewards. This deficit results in poor inhibitory control on basic tasks and during real-world behaviors that rely on similar processes.

RESUMO

The literature is inconsistent regarding whether childhood ADHD confers risk for adulthood problematic alcohol use, depressive symptoms, and their co-occurrence. These inconsistencies could be due to meaningful heterogeneity in the adulthood outcomes of children with ADHD that were obscured in traditional group-based analyses. The current study tested this possibility, as well as the contribution of adulthood ADHD symptom persistence, in order to clarify long-term risk in this population. Children diagnosed with ADHD and demographically-similar children without ADHD were followed longitudinally into adulthood and repeatedly assessed on heavy drinking, alcohol problems, and depressive symptoms from ages 21-29 (84.1% White (not Hispanic); 86.9% male; 51.2% childhood ADHD; 14.7% adulthood-persistent ADHD; N = 320). Group-based multi-trajectory modeling identified six groups with different combinations of trajectories across these variables. Heterogeneous longitudinal outcomes for those with ADHD were found. Some children with ADHD showed increased risk as typically predicted, with a higher likelihood of membership in a group with stable-moderate alcohol outcomes and stable-severe depression (adulthood persistent ADHD also predicted this group), whereas some children with ADHD were more likely to belong to a group with virtually no alcohol outcomes and low depression. Additionally, adulthood persistent ADHD predicted membership in a group with stable-severe alcohol outcomes and stable-moderate depression. Given the severity associated with co-occurring alcohol and depressive disorders, studies of early risk and protective factors and long-term outcomes for these disparate trajectory patterns are needed, particularly for those with childhood and persisting ADHD.

RESUMO

Adults with childhood attention-deficit hyperactivity disorder (ADHD) experience impairment in core functional domains (e.g., educational attainment, occupational status, social relationships, substance abuse, and criminal behavior), but it is currently unclear which impairments co-occur and whether subgroups experience differentiable patterns, none, or all aforementioned functional domains. Latent profile analysis (LPA) was used to characterize patterns of impairment. Data from the Pittsburgh ADHD Longitudinal Study were used. The 317 participants were 25 years old and had childhood ADHD. LPA characterized the variability across substance use (alcohol consumption, cigarette smoking, marijuana use), criminal behavior, peer impairment, educational attainment, maternal relationship, financial dependence, and sexual activity among young adults with childhood ADHD. Childhood predictors of profiles were examined, and ADHD profiles were compared to a matched comparison group without ADHD also followed longitudinally (n = 217). Five profiles were found: prototypic impairment group (54%), high binge-drinking group (17%), high marijuana use group (10%), high criminal activity group (3%), and high cross-domain impairment group (17%). All profiles were impaired compared to non-ADHD young adults. Childhood variables rarely significantly predicted profiles. Young adults with childhood ADHD have differentiable impairment patterns that vary based on substance use, criminal behavior, and number of clinically impaired domains. Nearly all young adult ADHD profiles were impaired in peer, educational, and financial domains, and there was not a nonimpaired ADHD profile. Use of specific substances was elevated among subgroups of, but not all, young adults with ADHD histories. Finally, the high cross-domain impairment profile was impaired in all domains.

RESUMO

A study conducted in an analogue summer treatment setting showed that when concurrently receiving behavioral intervention, many children with Attention-Deficit Hyperactivity Disorder (ADHD) did not need medication or maximized responsiveness at very low doses. The present study followed participants in that summer study into the subsequent school year to investigate whether the same pattern would extend to the natural school and home settings. There were 127 unmedicated children with ADHD between the ages of 5 and 13 who were randomly assigned to receive or not receive behavioral consultation (BC) at the start of the school year. Children were evaluated by teachers and parents each week to determine if central nervous system stimulant treatment was needed. Children who received BC were approximately half as likely those who did not (NoBC) to initiate medication use each week at school or home and used lower doses when medicated at school. This produced a 40% reduction in total methylphenidate exposure over the course of the school year. BC and NoBC groups did not significantly differ on end-of-year teacher or parent ratings of behavior, which were positive. Moreover, BC and NoBC groups did not significantly differ in cost of treatment; although children in the BC condition accrued additional costs via the BC, these costs were offset by the associated delay and reduction in medication use. Results add to a growing literature suggesting that the use of low-intensity behavioral intervention as a first-line treatment reduces or eliminates the need for medication in children with ADHD.

RESUMO

Objective: Test the hypothesis that alcoholism, including antisocial alcoholism, is more prevalent among mothers and fathers of children with versus without ADHD. Method: Mothers (312 ADHD group, 235 non-ADHD group) and fathers (291 ADHD group, 227 non-ADHD group) in the Pittsburgh ADHD Longitudinal Study were interviewed along with their adolescent and young adult offspring. Results: Maternal and paternal alcoholism, with and without comorbid antisociality, was more prevalent in the ADHD group. Paternal alcoholism without antisociality was only marginally higher for probands after controlling for paternal ADHD. Offspring conduct disorder comorbidity was associated with parental antisociality but not parental antisocial alcoholism. Conclusion: Our findings that 44% of proband fathers and 25% of proband mothers experienced alcohol problems with or without antisociality are further evidence of increased alcoholism prevalence in families affected by ADHD. Maternal alcoholism and antisociality are prominent contributors to this family-level vulnerability. These findings indicate the need to assess long-term offspring outcomes as a function of parental alcohol and externalizing comorbidities, and perhaps other indicators of parental alcoholism phenotype, as familial vulnerability unfolds across development.
