Persistent attention-deficit/hyperactivity disorder predicts socially oriented, but not physical/physiologically oriented, alcohol problems in early adulthood.

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.

A measure of functioning in adults With ADHD: Psychometric properties of the general life functioning scale-parent version.

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.

Beers with Peers: Childhood ADHD and Risk for Correlated Change in Perceived Peer and Personal Alcohol Use Across Young Adulthood.

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.

Functional Outcomes of Young Adults with Childhood ADHD: A Latent Profile Analysis.

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.

Randomized Trial of First-Line Behavioral Intervention to Reduce Need for Medication in Children with ADHD.

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.

Role of ADHD in the Co-Occurrence Between Heavy Alcohol Use and Depression Trajectories in Adulthood.

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is associated with greater heavy alcohol use and depressive symptoms in adulthood. Yet, few studies have investigated whether childhood ADHD predicts an increased association between heavy drinking and depression in adulthood when this co-occurrence becomes more common. We examined associations among heavy alcohol use and depression longitudinally from ages 21 to 29 and whether these associations differed for those with or without childhood ADHD, as well as for those with or without persistent ADHD in adulthood. METHODS: Data were from the Pittsburgh ADHD Longitudinal Study, a prospective cohort of children diagnosed with ADHD and demographically similar individuals without ADHD histories. ADHD symptoms in adulthood were self- and parent reported; depressive symptoms and frequency of drinking 5 or more drinks in a single drinking occasion were self-reported and measured at 5 time-points from ages 21 to 29. Depression and alcohol use were modeled in a multiple-group, parallel process longitudinal growth model. RESULTS: The slopes of heavy alcohol use and depression were significantly and positively associated from ages 25 to 29 but not at the younger ages. Although the strength of these associations did not differ by group (with or without ADHD, childhood or adulthood), the slopes of depression and heavy drinking at the older ages were highly variable and individuals with ADHD showed significantly faster growth in depression from ages 25 to 29. CONCLUSIONS: Due to the strengthening association between heavy drinking and depression for adults in their late 20s, and increasing depression for adults with ADHD histories, individuals with ADHD may be at greater risk for co-occurring depression and binge drinking. Negative reinforcement-related alcohol use may strengthen as these individuals age toward the fourth decade of life. More rigorous testing of this possibility is warranted.

The Effects of Stimulant Medication and Training on Sports Competence Among Children With ADHD.

The current study examined the relative efficacy of behavioral sports training, medication, and their combination in improving sports competence among youth with attention deficit/hyperactivity disorder (ADHD). Participants were 73 youth (74% male; 81% Hispanic) between the ages of 5 and 12 diagnosed with Diagnostic and Statistical Manual of Mental Disorders (4th ed.) ADHD enrolled in a Summer Treatment Program (STP). The study consisted of a 2 (medication: methylphenidate, placebo) × 2 (sports training: instruction and practice, recreational play) between-groups design and was conducted over a 3-week period during the STP. Sports training was conducted with a novel sport, badminton, to limit previous sport knowledge and to differentiate it from concurrent sports training that occurred within the STP. Objective and subjective measures of sports skills, knowledge, and behavior were collected. Results indicated that, relative to recreational play, brief sports training improved observed and counselor-rated measures of sports competence including sports skills, knowledge, game awareness, effort, frustration, and enjoyment. During sports training, medication incrementally improved children's observed rule following behavior and counselor-rated sportsmanship relative to placebo. In the absence of sports training, medication improved behavior, effort, and sport knowledge. Training in sports skills and rules produced the largest magnitude effects on sports-related outcomes. Therefore, skills training, rather than medication alone, should be used in conjunction with behavioral intervention to teach sports to youth with ADHD. It is recommended that medication be used only as an adjunct to highly structured sports skills training for youth who display high rates of negative behavior during sports activities.

Fathers with Childhood ADHD, Parenting, and Their Young Children's Behavior: Offspring of the Pittsburgh ADHD Longitudinal Study (PALS).

Despite high heritability, no research has followed children with ADHD to parenthood to study their offspring and parenting behaviors. Given greater prevalence of ADHD in males and lack of research involving fathers, this study evaluated offspring of fathers with and without ADHD histories for ADHD and disruptive behavior and compared fathers' parenting behaviors. Male fathers (N = 29) from the Pittsburgh ADHD Longitudinal Study (PALS) participated with their preschool-aged offspring. Fathers completed self-reported measures, and father-child dyads completed an interaction task. ADHD offspring had elevated ADHD symptoms and behavior dysregulation. All fathers displayed positive parenting. ADHD fathers reported lower supportive responses to their child's negative emotions than comparison fathers, yet rated their parenting as more efficacious. ADHD offspring were distinguishable as early as age 3; thus, earlier diagnosis and intervention may be feasible for this at-risk population. Future research should investigate the acceptability and efficacy of parent training for fathers with ADHD.

Anger-irritability as a mediator of attention deficit hyperactivity disorder risk for adolescent alcohol use and the contribution of coping skills.

BACKGROUND: Research on susceptibility to alcohol use disorder within the attention deficit/hyperactivity disorder (ADHD) population has begun to expand examination of putative moderators and mediators in order to develop effective treatments. Specific dysregulated emotions have been separately associated with ADHD and with alcohol use difficulties. The current study is the first to conjointly study these variables by testing anger-irritability as a mediator of ADHD risk for adolescent alcohol use. METHODS: Frequency of binge drinking, drunkenness, and alcohol problems were examined for 142 children with ADHD followed into adolescence and compared to 100 demographically similar youth without ADHD. Parent-rated anger-irritability was tested as a mediator. Behavioral and cognitive coping skills, which are key clinical treatment targets, were studied as moderators of these associations. RESULTS: Childhood ADHD was positively associated with anger-irritability and the drinking outcomes in adolescence. Anger-irritability mediated the association between ADHD and alcohol use problems, but not binge drinking or drunkenness. Behavioral and cognitive, but not avoidant, coping played a moderating role, but only of the association between childhood ADHD and anger-irritability. CONCLUSIONS: Active coping strategies by adolescents with ADHD may reduce the vulnerability to alcohol problems through a reduction of negative emotions. Future research on additional mediators and treatments that target these skills is encouraged.

Treatment Sequencing for Childhood ADHD: A Multiple-Randomization Study of Adaptive Medication and Behavioral Interventions.

Behavioral and pharmacological treatments for children with attention deficit/hyperactivity disorder (ADHD) were evaluated to address whether endpoint outcomes are better depending on which treatment is initiated first and, in case of insufficient response to initial treatment, whether increasing dose of initial treatment or adding the other treatment modality is superior. Children with ADHD (ages 5-12, N = 146, 76% male) were treated for 1 school year. Children were randomized to initiate treatment with low doses of either (a) behavioral parent training (8 group sessions) and brief teacher consultation to establish a Daily Report Card or (b) extended-release methylphenidate (equivalent to .15 mg/kg/dose bid). After 8 weeks or at later monthly intervals as necessary, insufficient responders were rerandomized to secondary interventions that either increased the dose/intensity of the initial treatment or added the other treatment modality, with adaptive adjustments monthly as needed to these secondary treatments. The group beginning with behavioral treatment displayed significantly lower rates of observed classroom rule violations (the primary outcome) at study endpoint and tended to have fewer out-of-class disciplinary events. Further, adding medication secondary to initial behavior modification resulted in better outcomes on the primary outcomes and parent/teacher ratings of oppositional behavior than adding behavior modification to initial medication. Normalization rates on teacher and parent ratings were generally high. Parents who began treatment with behavioral parent training had substantially better attendance than those assigned to receive training following medication. Beginning treatment with behavioral intervention produced better outcomes overall than beginning treatment with medication.

Comparative Cost Analysis of Sequential, Adaptive, Behavioral, Pharmacological, and Combined Treatments for Childhood ADHD.

We conducted a cost analysis of the behavioral, pharmacological, and combined interventions employed in a sequential, multiple assignment, randomized, and adaptive trial investigating the sequencing and enhancement of treatment for children with attention deficit hyperactivity disorder (ADHD; Pelham et al., 201X; N = 146, 76% male, 80% Caucasian). The quantity of resources expended on each child's treatment was determined from records that listed the type, date, location, persons present, and duration of all services provided. The inputs considered were the amount of physician time, clinician time, paraprofessional time, teacher time, parent time, medication, and gasoline. Quantities of these inputs were converted into costs in 2013 USD using national wage estimates from the Bureau of Labor Statistics, the prices of 30-day supplies of prescription drugs from the national Express Scripts service, and mean fuel prices from the Energy Information Administration. Beginning treatment with a low-dose/intensity regimen of behavior modification (large-group parent training) was less costly for a school year of treatment ($961) than beginning treatment with a low dose of stimulant medication ($1,669), regardless of whether the initial treatment was intensified with a higher "dose" or if the other modality was added. Outcome data from the parent study (Pelham et al., 201X) found equivalent or superior outcomes for treatments beginning with low-intensity behavior modification compared to intervention beginning with medication. Combined with the present analyses, these findings suggest that initiating treatment with behavior modification rather than medication is the more cost-effective option for children with ADHD.

ADHD and Marijuana-Use Expectancies in Young Adulthood.

OBJECTIVE: This study examined mean level differences in marijuana expectancies and the differential associations between expectancies and marijuana use for individuals with and without a history of Attention-Deficit/Hyperactivity Disorder (ADHD). BACKGROUND: Substance-use expectancies are a widely studied risk factor for alcohol and other drug use. The relations between marijuana-use expectancies and self-reported marijuana use have not been examined in young adults with ADHD, a population shown to be at risk for marijuana use. METHOD: Participants were 306 (190 ADHD and 116 non-ADHD) young adults (M age = 20.06, SD = 2.03) from the Pittsburgh ADHD Longitudinal Study (PALS) who provided data about marijuana use and marijuana-use expectancies. RESULTS: Individuals in the ADHD group reported lower levels of social enhancement, tension reduction, and cognitive and behavioral-impairment expectancies compared to individuals in the non-ADHD group. Positive and negative marijuana-use expectancies were associated with marijuana use frequency in the whole sample and statistically significant ADHD group by expectancy interactions were found. Sexual-enhancement expectancies were more strongly associated with marijuana use frequency among individuals with ADHD histories while cognitive behavioral-impairment expectancies were more strongly associated with marijuana use frequency among individuals without ADHD. CONCLUSIONS: Marijuana-use expectancies may be acquired, and operate differently, for individuals with and without ADHD histories. Although future research is needed to test this speculation, these differences may be associated with ADHD-related difficulties in higher order cognitive processes that affect the encoding and utilization of expectations regarding marijuana's effects.

Altered Lateral Prefrontal Cortex Functioning During Emotional Interference Resistance Is Associated With Affect Lability in Adults With Persisting Symptoms of Attention-Deficit/Hyperactivity Disorder From Childhood.

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.

The role of perceived parent drinking motives on alcohol use among adolescents with and without childhood attention-deficit/hyperactivity disorder.

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.

Motorsports involvement among adolescents and young adults with childhood ADHD.

Although children with attention-deficit/hyperactivity disorder (ADHD) are at risk for impulsive, health-endangering behavior, few studies have examined nonsubstance, use-related risk-taking behaviors. This study examined whether adolescents and young adults with ADHD histories were more likely than those without ADHD histories to report frequent engagement in motorsports, a collection of risky driving-related activities associated with elevated rates of physical injury. Path analyses tested whether persistent impulsivity, comorbid conduct disorder or antisocial personality disorder (CD/ASP), and heavy alcohol use mediated this association. Analyses also explored whether frequent motorsporting was associated with unsafe and alcohol-influenced driving. Two hundred twenty-one adolescent and young adult males (16-25 years old) diagnosed with ADHD in childhood and 139 demographically similar males without ADHD histories reported their motorsports involvement. Persistent impulsivity, CD/ASP, heavy drinking, and hazardous driving were also measured in adolescence/young adulthood. Adolescents and young adults with ADHD histories were more likely to report frequent motorsports involvement than those without childhood ADHD. Impulsivity, CD/ASP, and heavy drinking partially mediated this association, such that individuals with ADHD histories, who had persistent impulsivity or CD/ASP diagnoses, were more likely to engage in heavy drinking, which was positively associated with frequent motorsporting. Motorsports involvement was associated with more unsafe and alcohol-influenced driving, and this association was more often found among those with, than without, ADHD histories. Adolescents and young adults with ADHD histories, especially those with persisting impulsivity, comorbid CD/ASP and heavy drinking tendencies, are more likely to engage in motorsports, which may heighten risk of injury.

Single and Combined Effects of Multiple Intensities of Behavioral Modification and Methylphenidate for Children with ADHD in the Home Setting.

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.

Smoking-Specific Risk Factors in Early Adulthood That Mediate Risk of Daily Smoking by Age 29 for Children with ADHD.

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.

An evaluation of the effect of methylphenidate on working memory, time perception, and choice impulsivity in children with ADHD.

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.

Mindfulness as an Adjunct to Behavior Modification for Elementary-aged Children with ADHD.

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.

The Impact of ADHD on Maternal Quality of Life.

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.
