正念冥想在ADHD儿童干预中的应用

正念冥想是有意识、非评判地将注意集中于当下经验的方法。近年来,正念冥想作为一种潜在的方法被引进到ADHD儿童干预领域。因为ADHD儿童的特异性,为了增加正念冥想方案对ADHD儿童的适切性,研究者从练习设置、奖励系统、解释方式和家长纳入几个方面对标准的正念减压训练方案做了改编。越来越多的研究证据表明,正念冥想训练能有效地减轻ADHD儿童的核心缺陷、改善其内外化症状和亲子关系。本文通过对已有相关实证研究的分析认为这些积极的影响可能与ADHD儿童的执行功能与去中心化等心理功能的改善有关,而大脑相关区域激活模式的变化和结构的积极改变可能是正念冥想影响ADHD儿童的神经基础。文章也提出已有研究在内容和方法学上的不足及其以后的探究方向。     

COMT and DAT1 polymorphisms moderate the indirect effect of parenting behavior on youth ADHD symptoms through neurocognitive functioning

Although gene × environment interactions contribute to youth attention-deficit/hyperactivity disorder (ADHD) symptoms, the pathways mediating these influences are unknown. We tested genetic moderation of indirect effects from parenting behavior to youth ADHD symptoms through multiple neurocognitive factors. Two hundred and twenty-nine youth with and without ADHD were assessed at baseline (Wave 1; ages 5–10) and at a 2-year follow-up (Wave 2; ages 7–13). At Wave 1, youth completed a neurocognitive battery including measures of response inhibition, visuospatial working memory, and fluid reasoning, and a standardized parent–child interaction task yielding observational measures of positive and negative parenting. At Wave 2, youth psychopathology was rated by parents and teachers using multiple methods (i.e., structured interview, rating scale). We employed moderated multiple mediation and compared conditional indirect effects across youth genotypes at two biologically plausible genetic loci. Controlling for parent ADHD symptoms as well as youth demographic factors and co-occurring externalizing symptoms, these genetic factors moderated the indirect effect from Wave 1 parenting to multi-method/informant Wave 2 ADHD symptoms through Wave 1 neurocognitive functioning. This preliminary study is the first to identify genetic moderation of mediated effects underlying ADHD symptoms and suggests that specific gene × parenting interactions may underlie neurocognitive functioning deficits and subsequent ADHD.     

Cognitive Behavioral Therapy for Attention-Deficit/Hyperactivity Disorder in College Students: A Review of the Literature

The current review presents a theory-guided review of the existing cognitive behavioral therapy (CBT) interventions for attention-deficit/hyperactivity disorder (ADHD) in college students. Across the eight studies that investigated this topic, moderate reductions were shown in inattentive symptoms but little to no change was reported in hyperactive/impulsive symptoms. Results indicated a moderate treatment effect on self-reported quality of life and school/work functioning, yet less of an impact on GPA, response inhibition, social functioning, and executive functioning. Methodological and statistical problems and inconsistencies were noted. Since college students are emerging adults, it is likely that the optimum CBT intervention for college students with ADHD lies somewhere in between the existing clinic-based adult ADHD CBT interventions as well as the school-based adolescent ADHD psychosocial interventions. Directions for future research and recommendations for clinicians in university settings are provided in an attempt to further develop the existing college students CBT clinical research evidence base.     

The Association between Self-Regulation and Symptoms of Autism Spectrum Disorder in Preschoolers with Externalizing Behavior Problems

The purpose of the current study was to examine the role of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) symptoms in predicting deficits in self-regulation across the domains of executive functioning and emotion regulation. Parents of 40 preschoolers with externalizing behavior problems reported on children’s ADHD and ASD symptoms, and emotion regulation. Children completed a standardized executive functioning battery. Results indicated that 28% of parents and 53% of teachers rated children above the subclinical range on ASD symptoms. An interaction emerged such that higher ASD symptoms were only associated with poorer executive functioning for children with lower ADHD symptoms. However, ASD symptoms were predictive of poorer emotion regulation independent of ADHD symptoms. Findings revealed clinically significant ASD symptoms, which aided in explaining heterogeneity in self-regulation deficits.     

A Review of Pediatric Nonpharmacological Sleep Interventions: Effects on Sleep,Secondary Outcomes,and Populations With Co-occurring Mental Health Conditions

Sleep problems are common in school-age children and linked to numerous negative outcomes. Sleep disturbances are particularly common in children with mental health disorders, such as attention-deficit/hyperactivity disorder, depression, and anxiety. Despite frequent use of nonpharmacological pediatric sleep interventions to treat common sleep problems, there is a paucity of research on whether these interventions are effective. Further, it is unclear whether by targeting sleep, these interventions lead to broader improvements in the domains of functioning that are commonly affected by poor sleep. The present review includes 20 studies that evaluated nonpharmacological sleep treatments for school-aged youth, including 5 studies specifically focused on youth with externalizing or internalizing problems. Multimodal approaches consisting of psychoeducation and sleep hygiene in combination with other components were effective at treating insomnia and general sleep problems in typically developing samples. The addition of behavioral parent training to sleep interventions was effective for youth with externalizing problems, whereas incorporating cognitive strategies into sleep interventions for youth with internalizing problems was found to be ineffective. A variety of secondary outcomes were examined, with the strongest support emerging for improvement in anxiety and behavioral problems. Implications for clinical practice and future research directions are discussed.     

Mindfulness meditation improves cognition: Evidence of brief mental training

Although research has found that long-term mindfulness meditation practice promotes executive functioning and the ability to sustain attention, the effects of brief mindfulness meditation training have not been fully explored. We examined whether brief meditation training affects cognition and mood when compared to an active control group. After four sessions of either meditation training or listening to a recorded book, participants with no prior meditation experience were assessed with measures of mood, verbal fluency, visual coding, and working memory. Both interventions were effective at improving mood but only brief meditation training reduced fatigue, anxiety, and increased mindfulness. Moreover, brief mindfulness training significantly improved visuo-spatial processing, working memory, and executive functioning. Our findings suggest that 4 days of meditation training can enhance the ability to sustain attention; benefits that have previously been reported with long-term meditators.     

Sequenced neurocognitive and behavioral parent training for the treatment of ADHD in school-age children

The present study examines the potential of sequencing a neurocognitive intervention with behavioral parent training (BPT) to improve executive functions (EFs), psychiatric symptoms, and multiple indices of functional impairment in school-age children aged 7 to 11 years who have been diagnosed with attention-deficit/hyperactivity disorder (ADHD). Specifically, in a randomized controlled trial design, 85 children were assigned to either Cogmed Working Memory Training (CWMT) followed by an empirically supported, manualized BPT intervention, or to a placebo version of CWMT followed by the same BPT intervention. Working memory maintenance (i.e., attention control/short-term memory), working memory processing and manipulation, ADHD and oppositional defiant disorder (ODD) symptoms, impairment in parent–child dynamics, familial impairment, and overall functional compromise were evaluated as outcomes. The results suggest specific effects of the combined CWMT and BPT program on verbal and nonverbal working memory storage and nonverbal working memory processing and manipulation but no incremental benefits in regard to ADHD symptoms, ODD symptoms, and functional outcomes. The present findings do not support the hypothesis regarding the complementary and augmentative benefits of sequenced neurocognitive and BPT interventions for the treatment of ADHD. These results, the study’s limitations, and future directions for research are further discussed.     

Neuropsychological deficits in preschool as predictors of ADHD symptoms and academic achievement in late adolescence

High levels of ADHD symptoms are related to severe negative outcomes, which underscore the importance of identifying early markers of these behavior problems. The main aim of the present study was therefore to investigate whether neuropsychological deficits in preschool are related to later ADHD symptoms and academic achievement, over and above the influence of early ADHD symptom levels. The present study is unique because it includes a broader range of predictors compared to previous studies and the participants are followed over time for as long as 13 years (i.e., ages 5–18 years). Preschool data included measures of executive functioning and reaction time variability as well as emotional reactivity and emotion regulation of both positive and negative emotions. When controlling for early ADHD symptom levels, working memory, reaction time variability, and regulation of happiness/exuberance were significantly related to inattention whereas regulation of happiness/exuberance and anger reactivity were significantly related to hyperactivity/impulsivity. Furthermore, working memory and reaction time variability in preschool were significantly related to academic achievement in late adolescence beyond the influence of early ADHD symptoms. These findings could suggest that it is possible to screen for early neuropsychological deficits and thereby identify children who are at risk of negative outcomes. Furthermore, our results suggest that interventions need to look beyond executive functioning deficits in ADHD and also target the role of emotional functioning and reaction time variability. The importance of including both the positive and negative aspects of emotional functioning and distinguishing between emotion regulation and emotional reactivity was also demonstrated.     

Meditation has stronger relationships with mindfulness,kundalini, and mystical experiences than yoga or prayer

Contemplative practices can have profound effects on mindfulness and on physical and sensory and mystical experiences. Individuals who self-reported meditation, yoga, contemplative prayer, or a combination of practices and their patterns of practice were compared for mindfulness, kundalini effects, and mystical experiences. The results suggest that the amount of practice but not the pattern and social conditions of practice influences mindfulness and possibly mystical experiences. Meditation, yoga, contemplative prayer, or a combination of practices all were found to be associated with enhancements of mindfulness, kundalini effects, and mystical experiences, but meditation had particularly strong associations and may be the basis of the associations of yoga and prayer with these outcomes. The results further suggest that the primary association of contemplative practices is with the real time awareness and appreciation of sensory and perceptual experiences which may be the intermediary between disparate practices and mindfulness, kundalini effects, and mystical experiences.     

Co-occurring Mental Health Problems and Peer Functioning Among Youth with Attention-Deficit/Hyperactivity Disorder: A Review and Recommendations for Future Research

It is well established that children and adolescents with attention-deficit/hyperactivity disorder (ADHD) frequently experience co-occurring mental health problems in addition to difficulties in their peer relationships. Although substantial research has focused on the extent to which peer functioning contributes to subsequent co-occurring mental health problems, much less research has considered how co-occurring mental health problems affect peer functioning domains. Therefore, the purpose of this review is to examine the effect of co-occurring mental health problems on the peer functioning of youth with ADHD. The impact of co-occurring externalizing (i.e., oppositional defiant disorder, conduct disorder) and internalizing (i.e., anxiety, depression) symptoms are reviewed, with a focus on whether these co-occurring symptoms exacerbate, attenuate, or have no effect across peer domains of social skills/competence, peer status, and friendship among youth with ADHD. Drawing from a developmental psychopathology framework, this review then draws attention to relevant causal processes and developmental cascades (including social-cognitive, affective, and family and parenting factors) in offering promising avenues for future work.     

Review of the Evidence for Motivation Deficits in Youth with ADHD and Their Association with Functional Outcomes

Preeminent theories of attention-deficit/hyperactivity disorder (ADHD) suggest that motivation deficits are core underlying features of the disorder. However, it is currently unclear whether empirical evidence supports the assertion that significant group (ADHD v. comparison) differences in motivation exist or that problems with motivation contribute to the functional impairments that youth with ADHD experience. Accordingly, this review focused on evaluating and summarizing the empirical literature on the presence of motivation deficits and their association with functional outcomes in samples of youth with ADHD. Twenty studies met the review inclusion criteria. Results support the assertion that youth with ADHD have lower academic-related motivation in comparison to their peers and that motivation plays an important role in academic outcomes, with the strongest evidence to date for reading achievement. However, the available evidence is limited, and few existing studies are aligned with the much larger theoretical and empirical motivation literature in typically developing youth. Given preliminary evidence that motivation plays a role in the academic impairments of youth with ADHD, the review concludes with a discussion of whether current ADHD interventions adequately target motivation and highlights important future directions.     

What outcomes have mindfulness and meditation interventions for managers and leaders achieved? A systematic review

No systematic review had previously been conducted examining the benefits mindfulness or meditation interventions for leaders and managers. However, the literature suggested that such interventions would have a positive impact on leaders’ own well-being, their leadership capability, their “post-conventional” leadership capacity, and their direct reports. The purpose of this study was therefore to systematically review research on mindfulness or meditation interventions for managers and leaders. Our review identified 19 studies that met the inclusion criteria. Findings indicate some encouraging signs that mindfulness and meditation interventions may improve aspects of leaders’/managers’ well-being and resilience, and leadership capability, possibly including their “post-conventional” leadership, but research results are very variable in quality and strength, and there was no evidence on benefits for participants’ direct reports. The studies reviewed explored a diversity of interventions, but provided little insight into which mindfulness and meditation interventions for managers and leaders are most effective, in what context they are best applied, or for whom they are most suitable. While the sub-set of studies that measured mindfulness found that the interventions used did increase participants’ mindfulness, there was no exploration of whether improved mindfulness was the mechanism by which other positive outcomes were achieved.     

Interventions to Address the Academic Impairment of Children and Adolescents with ADHD

There exists a strong link between ADHD and academic underachievement. Both the core behavioral symptoms of ADHD and associated executive functioning deficits likely contribute to academic impairment. Current evidence-based approaches to the treatment of ADHD (i.e., stimulant medication, clinical behavior therapy and classroom behavioral interventions) have demonstrated a robust impact on behavioral variables such as attention and disruptive behavior within classroom analogue settings; however, their efficacy in improving academic outcomes is much less clear. Although surprisingly few treatment outcome studies of ADHD have attempted to incorporate interventions that specifically target academic outcomes, the studies that are available suggest that these interventions may be beneficial. The state of the treatment literature for addressing academic impairment in children and adolescents with ADHD will be reviewed herein, as well as limitations of current research, and directions for future research.     

Comorbid ADHD: Implications for the Treatment of Anxiety Disorders in Children and Adolescents

Despite high comorbidity rates and potential clinical implications, the influence of co-occurring attention-deficit/hyperactivity disorder (ADHD) on outcomes of cognitive-behavioral treatment (CBT) for anxious youth remains poorly understood. In this qualitative review, the current literature on the influence of comorbid ADHD on CBT of youth with diverse anxiety disorders is explored. Peer-reviewed studies examining ADHD, at the diagnostic and symptom level, received highest priority. In addition, inasmuch as some studies did not isolate the effects of ADHD from other disruptive behavior disorders (DBDs: oppositional defiant disorder, conduct disorders), studies with the three DBDs were explored as well. Ten studies met our specified methodological criteria. Findings are discussed in relation to the following two factors: type of anxiety disorder and measurement of ADHD (diagnostic or symptom level) in these studies. There was evidence that youth with a variety of anxiety disorders and with co-occurring ADHD fared worse than their counterparts without ADHD. Additionally, grouping ADHD with other DBDs tended to obscure the negative impact of ADHD on treatment outcomes. Additional research is needed to delineate the influence of comorbid ADHD specifically on treatment outcomes for the various anxiety disorders. Clinical implications of treating anxious youth with comorbid ADHD are explored.     

Executive Function in Pediatric Bipolar Disorder and Attention-Deficit Hyperactivity Disorder: In Search of Distinct Phenotypic Profiles

Often, there is diagnostic confusion between bipolar disorder (BD) and attention-deficit hyperactivity disorder (ADHD) in youth due to similar behavioral presentations. Both disorders have been implicated as having abnormal functioning in the prefrontal cortex; however, there may be subtle differences in the manner in which the prefrontal cortex functions in each disorder that could assist in their differentiation. Executive function is a construct thought to be a behavioral analogy to prefrontal cortex functioning. We provide a qualitative review of the literature on performance on executive function tasks for BD and ADHD in order to determine differences in task performance and neurocognitive profile. Our review found primary differences in executive function in the areas of interference control, working memory, planning, cognitive flexibility, and fluency. These differences may begin to establish a pediatric BD profile that provides a more objective means of differential diagnosis between BD and ADHD when they are not reliably distinguished by clinical diagnostic methods.     

Developmental change in the relation between executive functions and symptoms of ADHD and co‐occurring behaviour problems

In a sample of 92 children aged 6–13 years this study investigates the normal developmental change in the relation between executive functioning (EF) and the core behavioural symptoms associated with attention deficit hyperactivity disorder (ADHD) (hyperactivity/impulsivity and inattention) as well as symptoms often co‐occurring with childhood hyperactivity (conduct‐ and internalizing problems). EF was assessed by using multiple tests grouped through prior factor analysis, resulting in cognitive measures relating to disinhibition, speed/arousal, verbal working memory, non‐verbal working memory, and fluency. The results showed that although disinhibition was positively related to hyperactivity/impulsivity and inattention mainly for the youngest age group, there were no significant age effects for these relations. Instead, age effects were found for the relations between speed/arousal and inattention as well as for the relations between verbal working memory/fluency and inattention. In the oldest age group poor performance on these cognitive measures was associated with high ratings of inattention. For the total sample a relation was obtained between disinhibition and hyperactivity/impulsivity as well as between both working memory measures and internalizing problems. In conclusion, the results from this study suggest that poor inhibition is most clearly associated with ADHD symptoms for younger children, whereas poor functioning with regard to later developing and more complex executive functions such as working memory and fluency is associated with ADHD symptoms for older children.

Bending the Curve: A Community-Based Behavioral Parent Training Model to Address ADHD-Related Concerns in the Voluntary Sector in Denmark

Limited access to evidence-based behavioral parent training (BPT) for addressing attention deficit/hyperactivity disorder (ADHD) has been a growing concern internationally. Models to improve access to BPT are needed, particularly those that can be readily implemented in community settings and that leverage the potential workforce to increase capacity to deliver BPT. The purpose of this study was to evaluate a BPT model which included oft-used content, methods, processes of BPT (common-elements), non-professionally delivered (task-shifted/shared) BPT intervention, and an efficient ancillary support system (training, fidelity, and supervision methods) for families of youth with parental concerns about ADHD. In a randomized controlled trial of 161 families of children (79% male; mean age 7.04 [1.55]), the Caring in Chaos (CiC) BPT model, delivered by community volunteers across 12 community-based sites in Denmark, was compared to a wait-list control condition on key child and parent outcomes at immediate post-treatment and 4-month follow-up assessment points. Results suggested that the CiC model led to significantly greater improvement in parenting behavior, parenting sense of competence, child functional impairment, parental stress and parental depressive symptoms compared to the wait list condition at immediate post-treatment, with maintenance of gains in most of these areas at follow-up assessment. No effect of intervention was found on ADHD symptoms. The results of this study suggest that developing efficient BPT intervention models, such as the CiC model, can result in readily implemented interventions by a variety of individuals in community settings. Such models are necessary to bend the curve on addressing unmet needs of families of youth with concerns about ADHD.     

Externalizing Outcomes of Youth with and without ADHD: Time-Varying Prediction by Parental ADHD and Mediated Effects

Although parental attention-deficit/hyperactivity disorder (ADHD) is a risk factor for multiple negative youth outcomes, it is unknown how change in parental ADHD symptoms over time affects change in child ADHD symptoms; moreover, mediators of these predictions are largely unknown. Parents of 230 5–10 year-old children (68 % male) with (n = 120) and without ADHD (n = 110) were followed prospectively for 6–7 years across three separate waves. Parents self-reported their ADHD and depression symptoms and similarly rated offspring ADHD, oppositional defiant disorder (ODD), and conduct disorder (CD) symptoms; youth self-reported their substance use. Temporally-ordered mediators consisted of parental expressed emotion (EE), derived from the Five Minute Speech Sample, and self-reported positive and negative parenting behavior. Controlling for key demographics and parental depression symptoms, increasing parental ADHD symptoms were a time-varying predictor of worsening youth ADHD and ODD, although it was unrelated to change in CD and alcohol/substance use. Next, although EE facets (i.e., criticism, emotional over-involvement) did not mediate these predictions, negative parenting behavior significantly mediated predictions of youth ADHD (and marginally in predictions of ODD) from parental ADHD symptoms. These quasi-experimental findings suggest that parental ADHD symptoms are a potential unique causal risk factor for offspring ADHD and ODD; also, preventing negative parenting behavior secondary to parental ADHD symptoms is critical to improve trajectories of youth ADHD and ODD. We consider parental ADHD symptoms and family factors underlying emergent externalizing problems utilizing a developmental psychopathology framework, including implications for intervention and prevention.     

Executive functions and ADHD in adults: evidence for selective effects on ADHD symptom domains

Dual-process models of attention-deficit/hyperactivity disorder (ADHD) suggest that both executive functioning and regulatory functions (e.g., processing speed) are involved and that executive function weaknesses may be associated specifically with symptoms of inattention-disorganization but not hyperactivity-impulsivity. Adults aged 18-37 (105 with ADHD, 90 controls) completed a neuropsychological battery. The ADHD group had weaker performance than did the control group (p<.01) on both executive and speed measures. Symptoms of inattention-disorganization were uniquely related to executive functioning with hyperactivity-impulsivity controlled. Inattention was associated with slower response speed, and hyperactivity-impulsivity with faster output speed. Results were not accounted for by IQ, age, gender, education level, or comorbid disorders. Findings are discussed in terms of developmental and dual-process models of ADHD leading into adulthood.     

Relations between Parenting Stress,Parenting Style,and Child Executive Functioning for Children with ADHD or Autism

Relations among parenting stress, parenting style, and child executive functioning for children with disabilities are not easily teased apart. The current study explored these relations among 82 children and adolescents age 7–18: 21 with attention deficit/hyperactivity disorder, 33 with autism spectrum disorder, and 28 typically developing. Results indicated that children with attention deficit/hyperactivity disorder or autism spectrum disorder had more executive functioning deficits, and their parents reported more parenting stress and a greater use of permissive parenting, compared to typically developing children. In general, increased parenting stress was associated with greater use of authoritarian and permissive parenting styles, as well as more problems with behavior regulation for children. Authoritarian and permissive parenting styles were associated with poorer child executive functioning. Child diagnostic group (attention deficit/hyperactivity disorder, autism spectrum disorder, typically developing) moderated relations between parent stress and child functioning, and between parenting style and child functioning. Implications for intervention with families of children with disabilities are discussed.
