ADHD is best understood as a cultural construct

Spectralities of ADHD: hauntological diagnosis amidst agency, politics and pedagogies

Hauntology has become an increasingly alluring concept in social sciences to reflect upon everyday life and how subjects dwell upon scenarios pervaded not only by the potency of the actual but also the haunting of the past and the virtual. Drawing on the concept of 'hauntology', we inquire about recurring temporalities and spectrality themes concerning the 'controversial' diagnosis of attention deficit hyperactivity disorder (ADHD) in Chile. Using participant observation and in-depth interviews with health practitioners, teachers, school staff, diagnosed children, and their peers from 3-year-long research, we examine how the performance of the diagnosis by clinicians at times can produce a modification of the temporality of the diagnosed children from that moment forth. Amidst tension created by educational policies, ideas of well-being, pedagogical practices, and everyday living, the diagnosis keeps repeating its agentic capacity while resisting its decay, becoming ever-present and actual. Once cast, the diagnosis acts as a repeating force that can shape every experience, cancelling the possibility for the child to become different by unfolding out of the diagnosis.

The Impact of Adverse Childhood Experiences on Symptom and Performance Validity Tests Among a Multiracial Sample Presenting for ADHD Evaluation

OBJECTIVE

Adverse childhood experiences (ACEs) are commonly reported in individuals presenting for attention-deficit hyperactivity disorder (ADHD) evaluation. Performance validity tests (PVTs) and symptom validity tests (SVTs) are essential to ADHD evaluations in young adults, but extant research suggests that those who report ACEs may be inaccurately classified as invalid on these measures. The current study aimed to assess the degree to which ACE exposure differentiated PVT and SVT performance and ADHD symptom reporting in a multi-racial sample of adults presenting for ADHD evaluation.

METHOD

This study included 170 adults referred for outpatient neuropsychological ADHD evaluation who completed the ACE Checklist and a neurocognitive battery that included multiple PVTs and SVTs. Analysis of variance was used to examine differences in PVT and SVT performance among those with high (≥4) and low (≤3) reported ACEs.

RESULTS

Main effects of the ACE group were observed, such that high ACE group reporting demonstrated higher scores on SVTs assessing ADHD symptom over-reporting and infrequent psychiatric and somatic symptoms on the Minnesota Multiphasic Personality Inventory-2-Restructured Form. Conversely, no significant differences emerged in total PVT failures across ACE groups.

CONCLUSIONS

Those with high ACE exposure were more likely to have higher scores on SVTs assessing over-reporting and infrequent responses. In contrast, ACE exposure did not affect PVT performance. Thus, ACE exposure should be considered specifically when evaluating SVT performance in the context of ADHD evaluations, and more work is needed to understand factors that contribute to different patterns of symptom reporting as a function of ACE exposure.

Cross-Cultural Adult ADHD Assessment in 42 Countries Using the Adult ADHD Self-Report Scale Screener

OBJECTIVE

We analyzed adult ADHD symptoms in a cross-cultural context, including investigating the occurrence and potential correlates of adult ADHD and psychometric examination of the Adult ADHD Self-Report Scale (ASRS) Screener.

METHOD

Our analysis is based on a large-scale research project involving 42 countries (International Sex Survey, N=72,627, 57% women, Mage=32.84; SDage=12.57).

RESULTS

The ASRS Screener demonstrated good reliability and validity, along with partial invariance across different languages, countries, and genders. The occurrence of being at risk for adult ADHD was relatively high (21.4% for women, 18.1% for men). The highest scores were obtained in the US, Canada, and other English-speaking Western countries, with significantly lower scores among East Asian and non-English-speaking European countries. Moreover, ADHD symptom severity and occurrence were especially high among gender-diverse individuals. Significant associations between adult ADHD symptoms and age, mental and sexual health, and socioeconomic status were observed.

CONCLUSIONS

Present results show significant cross-cultural variability in adult ADHD occurrence as well as highlight important factors related to adult ADHD. Moreover, the importance of further research on adult ADHD in previously understudied populations (non-Western countries) and minority groups (gender-diverse individuals) is stressed. Lastly, the present analysis is consistent with previous evidence showing low specificity of adult ADHD screening instruments and contributes to the current discussion on accurate adult ADHD screening and diagnosis.

Perspectives on ADHD in children and adolescents as a social construct amidst rising prevalence of diagnosis and medication use

The diagnosis of attention-deficit hyperactivity disorder (ADHD) is based on the presence of pervasive, persistent symptoms of inattention and/or hyperactivity/impulsivity typically emerging early in life and resulting in significant functional impairment. In contrast to a worldwide epidemiological prevalence of approximately 5% in children and 2-3% in adults, there are significant variations in the prevalence of administrative ADHD diagnoses and medication use. We assert that in order to explore the underlying dynamics of this phenomenon, a thorough understanding of the construct ADHD is necessary. We contend that ADHD is not a natural entity that unfolds within an individual and can be understood independent from societal and environmental factors, but rather that ADHD as a diagnosis can better be conceptualized as a valid and pragmatically useful social construct. Decisions to diagnose and treat ADHD should follow a person-centered approach and be focused on functional impairment within a socially constructed, context-dependent and environmentally contingent model.

ADHD Diagnosis in Children of Non-US-Born Parents: A Cross-Sectional Analysis

OBJECTIVE(S)

To assess the likelihood of ADHD diagnosis in children of non-US-born caregivers relative to children of US-born caregivers.

METHOD

Cross-sectional analysis of a combined 2016 to 2019 National Survey of Children's Health dataset (n = 109,881) was performed to identify associations between caregiver's birth outside the U.S. and child's ADHD diagnosis. Logistic regression models adjusted for potential sociodemographic confounders.

RESULTS

Children with one or two non-US-born caregivers were less likely to be diagnosed with ADHD (aOR = 0.58, p < .001; aOR = 0.59, p < .001, respectively). Likelihood of a diagnosis increased as non-US-born caregivers spent more time in the US. After a diagnosis, children of two non-US-born caregivers were less likely to be treated with medication.

CONCLUSION

The lower likelihood of ADHD diagnosis in children with non-US-born caregivers may reflect an increasing need for public health education to raise awareness about ADHD among this population and the development of culturally sensitive ADHD identification methodologies.

Experiences of children and adolescents with attention-deficit/hyperactivity disorder taking methylphenidate

To improve clinical counselling for adolescents about the use of stimulant medication, it is crucial to understand the experiences of young people diagnosed with attention-deficit/hyperactivity disorder (ADHD) who are taking such treatment. For this narrative review, five databases were searched for studies investigating the personal experiences of control issues in adolescents diagnosed with ADHD taking methylphenidate. We extracted the data using NVivo 12 and interpretatively synthesized them according to the procedures of thematic analysis. Interviewed youngsters spontaneously put forward self-experiences about self-esteem and sense of control, although these issues were rarely explicitly addressed in the research question. The overarching theme in these studies was 'improving the self'. Two subthemes emerged: (1) medication sometimes delivered on its promise to improve the self, but regularly it did not; and (2) youngsters felt pressurized to conform to behavioural norms and comply with the medication use that adults had decided on. To genuinely involve youngsters diagnosed with ADHD for whom stimulant medication is prescribed in the shared decision-making process, we recommend to specifically involve them in a dialogue on the medication's potential effects on their self-experiences. This will allow them to feel at least partly in control of their body and life, and less pressurized to conform to others' norms.

When ADHD knocks on the door - discourse theory as a frame to explore subject positions and mental wellbeing before diagnosis

PURPOSE

Attention deficit hyperactivity disorder (ADHD) is currently the most prevalent childhood psychiatric diagnosis. This article reports how 10 young adults in Norway positioned themselves before they were diagnosed with ADHD either during early childhood or adolescence. A central theme is how these subject-positions relate to societal norms and mental well-being.

METHOD

Individual interviews were conducted, and the transcriptions of the interviews were analysed according to discourse theory.

RESULT

Six central subject positions were identified which in turn related to two major positions: 1) failure with schoolwork and 2) struggle in social interaction. The findings indicated specific emotional and environmental needs and that individuals were confronted with societal norms related to the criteria for ADHD prior to and regardless of whether one had received a formal diagnosis.

CONCLUSION

We argue that analysing subject positions provides important knowledge regarding ADHD that is useful for individuals, parents, teachers, practitioners, policymakers, and helping professionals in the field of mental health and education when it comes to interventions that support children who possess different temperaments.

A Narrative Review of the Association between Prematurity and Attention-Deficit/Hyperactivity Disorder and Accompanying Inequities across the Life-Course

Preterm birth is associated with an increased risk of neurodevelopmental and neurobehavioral impairments including attention-deficit/hyperactivity disorder (ADHD), the most common neurobehavioral disorder of childhood. In this narrative review, we examine the known associations between prematurity and ADHD and highlight the impact of both prematurity and ADHD on multiple domains across the pediatric life-course. We develop a framework for understanding the health services journey of individuals with ADHD to access appropriate services and treatments for ADHD, the "ADHD Care Cascade". We then discuss the many racial and ethnic inequities that affect the risk of preterm birth as well as the steps along the "ADHD Care Cascade". By using a life-course approach, we highlight the ways in which inequities are layered over time to magnify the neurodevelopmental impact of preterm birth on the most vulnerable children across the life-course.

Methylphenidate for children and adolescents with attention deficit hyperactivity disorder (ADHD)

BACKGROUND

Attention deficit hyperactivity disorder (ADHD) is one of the most commonly diagnosed and treated psychiatric disorders in childhood. Typically, children and adolescents with ADHD find it difficult to pay attention and they are hyperactive and impulsive. Methylphenidate is the psychostimulant most often prescribed, but the evidence on benefits and harms is uncertain. This is an update of our comprehensive systematic review on benefits and harms published in 2015.

OBJECTIVES

To assess the beneficial and harmful effects of methylphenidate for children and adolescents with ADHD.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, three other databases and two trials registers up to March 2022. In addition, we checked reference lists and requested published and unpublished data from manufacturers of methylphenidate.

SELECTION CRITERIA

We included all randomised clinical trials (RCTs) comparing methylphenidate versus placebo or no intervention in children and adolescents aged 18 years and younger with a diagnosis of ADHD. The search was not limited by publication year or language, but trial inclusion required that 75% or more of participants had a normal intellectual quotient (IQ > 70). We assessed two primary outcomes, ADHD symptoms and serious adverse events, and three secondary outcomes, adverse events considered non-serious, general behaviour, and quality of life.

DATA COLLECTION AND ANALYSIS

Two review authors independently conducted data extraction and risk of bias assessment for each trial. Six review authors including two review authors from the original publication participated in the update in 2022. We used standard Cochrane methodological procedures. Data from parallel-group trials and first-period data from cross-over trials formed the basis of our primary analyses. We undertook separate analyses using end-of-last period data from cross-over trials. We used Trial Sequential Analyses (TSA) to control for type I (5%) and type II (20%) errors, and we assessed and downgraded evidence according to the GRADE approach.

MAIN RESULTS

We included 212 trials (16,302 participants randomised); 55 parallel-group trials (8104 participants randomised), and 156 cross-over trials (8033 participants randomised) as well as one trial with a parallel phase (114 participants randomised) and a cross-over phase (165 participants randomised). The mean age of participants was 9.8 years ranging from 3 to 18 years (two trials from 3 to 21 years). The male-female ratio was 3:1. Most trials were carried out in high-income countries, and 86/212 included trials (41%) were funded or partly funded by the pharmaceutical industry. Methylphenidate treatment duration ranged from 1 to 425 days, with a mean duration of 28.8 days. Trials compared methylphenidate with placebo (200 trials) and with no intervention (12 trials). Only 165/212 trials included usable data on one or more outcomes from 14,271 participants. Of the 212 trials, we assessed 191 at high risk of bias and 21 at low risk of bias. If, however, deblinding of methylphenidate due to typical adverse events is considered, then all 212 trials were at high risk of bias.

PRIMARY OUTCOMES

methylphenidate versus placebo or no intervention may improve teacher-rated ADHD symptoms (standardised mean difference (SMD) -0.74, 95% confidence interval (CI) -0.88 to -0.61; I² = 38%; 21 trials; 1728 participants; very low-certainty evidence). This corresponds to a mean difference (MD) of -10.58 (95% CI -12.58 to -8.72) on the ADHD Rating Scale (ADHD-RS; range 0 to 72 points). The minimal clinically relevant difference is considered to be a change of 6.6 points on the ADHD-RS. Methylphenidate may not affect serious adverse events (risk ratio (RR) 0.80, 95% CI 0.39 to 1.67; I² = 0%; 26 trials, 3673 participants; very low-certainty evidence). The TSA-adjusted intervention effect was RR 0.91 (CI 0.31 to 2.68).

SECONDARY OUTCOMES

methylphenidate may cause more adverse events considered non-serious versus placebo or no intervention (RR 1.23, 95% CI 1.11 to 1.37; I² = 72%; 35 trials 5342 participants; very low-certainty evidence). The TSA-adjusted intervention effect was RR 1.22 (CI 1.08 to 1.43). Methylphenidate may improve teacher-rated general behaviour versus placebo (SMD -0.62, 95% CI -0.91 to -0.33; I² = 68%; 7 trials 792 participants; very low-certainty evidence), but may not affect quality of life (SMD 0.40, 95% CI -0.03 to 0.83; I² = 81%; 4 trials, 608 participants; very low-certainty evidence).

AUTHORS' CONCLUSIONS

The majority of our conclusions from the 2015 version of this review still apply. Our updated meta-analyses suggest that methylphenidate versus placebo or no-intervention may improve teacher-rated ADHD symptoms and general behaviour in children and adolescents with ADHD. There may be no effects on serious adverse events and quality of life. Methylphenidate may be associated with an increased risk of adverse events considered non-serious, such as sleep problems and decreased appetite. However, the certainty of the evidence for all outcomes is very low and therefore the true magnitude of effects remain unclear. Due to the frequency of non-serious adverse events associated with methylphenidate, the blinding of participants and outcome assessors is particularly challenging. To accommodate this challenge, an active placebo should be sought and utilised. It may be difficult to find such a drug, but identifying a substance that could mimic the easily recognised adverse effects of methylphenidate would avert the unblinding that detrimentally affects current randomised trials. Future systematic reviews should investigate the subgroups of patients with ADHD that may benefit most and least from methylphenidate. This could be done with individual participant data to investigate predictors and modifiers like age, comorbidity, and ADHD subtypes.

Screen Time and ADHD Behaviors in Chinese Children: Findings From Longitudinal and Cross-Sectional Data

OBJECTIVE

Research suggests that screen exposure presents a risk for ADHD behaviors in young children. However, the operationalization of screen exposure remains murky and longitudinal data is scarce. In this paper, we examined the relations between better operationalized daily screen time and behaviors of inattention and behaviors of hyperactivity/impulsivity in three cohorts of community samples of young Chinese children.

METHOD

Study 1 was longitudinal and included 111 children who were 3.6 years old (Range = 2.4-4.9; SD = 0.4) at Baseline and 4.8 years old (Range = 3.9-6.0; SD = 0.4) at Follow-Up. Study 2 was cross-sectional and included 172 children aged 4.9 years (Range = 3.0-7.1; SD = 1.0). Study 3 was also cross-sectional and included 313 children who were 6.9 years old (Range = 5.7-8.3; SD = 0.4). In each study, the parents reported how much time that their children spent daily on iPad/tablet, smart phone, and online games and watching TV in the previous week, and their children's behaviors of inattention (I/A) and hyperactivity/impulsivity (H/I).

RESULTS

Regression analysis revealed that in Study 1, controlling for child demographics, mother's education, family SES, and corresponding I/A or H/I scores at Baseline, screen time at Baseline predicted I/A scores (β = .27, p < .01) and H/I scores (β = .32, p < .001) at Follow-Up. Similarly, controlling for covariates, screen time predicted I/A scores (β = .25, p < .01) and H/I scores (β = .25, p < .01) in Study 2; I/A scores (β = 0.16, p < .01) and H/I scores (β = .15, p < .05) in Study 3.

CONCLUSION

Screen exposure was a risk for inattention and hyperactivity/impulsivity behaviors in urban Chinese children.

Debate: 'A rose by any other name' would smell as sweet - myths peddled about the ills of diagnosing conduct disorders

Using a diagnosis of ODD/CD enables the clinician to apply a huge amount of helpful information about what has caused the concerns and then to offer effective treatment. More often than not, they do not use a diagnostic label with the family; the point is for the clinician to share the expertise. Myths about the nature of psychiatric diagnosis and the harms of a label of ODD/CD are debunked in this article. It is society who stigmatises these individuals because of their antisocial behaviour, and withholding skilfully applied benefits of the accumulated knowledge of the condition is cruel and especially harmful to disadvantaged groups in society where ODD/CD is far more prevalent.

Annual Research Review: Attention-deficit/hyperactivity disorder in girls and women: underrepresentation, longitudinal processes, and key directions

Attention-deficit/hyperactivity disorder (ADHD) - and its underlying behavioral dimensions of inattention and hyperactivity-impulsivity - have been understudied in females. We first cover the conceptual issues of prevalence, diagnostic practices, diversity, comorbidity, and causal factors, plus forces limiting awareness of ADHD in females. After a narrative review of cross-sectional and longitudinal findings, we conclude the following. (a) Girls meet diagnostic criteria for ADHD at just under half the rates of boys, a ratio that becomes much closer to equal by adulthood. (b) Girls and women with ADHD show a predominance of inattention and associated internalizing problems; boys and men display greater levels of hyperactive-impulsive symptoms and associated externalizing problems. (c) Sex differences in ADHD symptoms and related outcomes depend heavily on the clinical versus nonreferred nature of the samples under investigation. (d) Females with ADHD experience, on average, serious impairments, with a particularly heightened risk for problems in close relationships and engagement in self-harm. (e) Clinicians may overlook symptoms and impairments in females because of less overt (but still impairing) symptom manifestations in girls and women and their frequent adoption of compensatory strategies. Our review of predictors and mediators of adult outcomes highlights (a) the potential for heterotypically continuous pathways in females with childhood ADHD and (b) developmental progressions to self-harm, intimate partner violence, unplanned pregnancy, and comorbid psychopathology. Focusing on ADHD in females is necessary to characterize causal and maintaining mechanisms with accuracy and to foster responsive interventions, as highlighted in our closing list of clinical implications and research priorities.

Do we over-diagnose ADHD in North America? A critical review and clinical recommendations

There has been a marked increase in the prevalence of attention-deficit/hyperactivity disorder (ADHD) in the last 25 years in North America. Some see this trend as positive and believe that it reflects a better identification of ADHD and even think that the disorder is still under-diagnosed. Others, however, contend that ADHD is over-diagnosed. To help mental health clinicians to maintain an informed and nuanced perspective on this debate, this critical review aims to (1) summarize empirical results on factors that might contribute to increase the number of ADHD diagnoses and (2) propose clinical recommendations coherent with these findings to improve clinical practices for ADHD assessment and treatment. We conclude that artifactual factors such as current formulation of diagnostic criteria, clinical practices, and inordinate focus on performance, which is rampant in North America, likely contribute to inflated prevalence rates.

The Benefits and Limitations of Stimulants in Treating ADHD

This chapter focusses on the benefits and limitations of stimulant medications in the treatment of ADHD. We highlight the key similarities and differences between the different stimulants used to treat ADHD and briefly discuss mechanisms of action, pharmacokinetics, and pharmacodynamics. We will discuss some of the political, ethical, and moral discussions about the use of stimulants including a consideration of the treatment of subsyndromal ADHD and the use of stimulants as cognitive enhancers. We review the comparative efficacy and effectiveness between stimulants and non-pharmacological treatments for ADHD, between stimulant classes and formulations and between stimulant and non-stimulant medications. We discuss the effects on core symptoms, common associated symptoms, cognition, and more distal outcomes including quality of life and functioning and issues related to tolerance, tolerability and adverse effects. Looking at the clinical implications of these findings, we discuss the importance of measurement-based care in the treatment of ADHD. Finally, we will look at the benefits and limitations of stimulants across several different populations and clinical subgroups.

Fifteen-minute consultation: To prescribe or not to prescribe in ADHD, that is the question

Attention-deficit hyperactivity disorder (ADHD) is fraught with controversy. Some clinicians believe it is a biological neurodevelopmental disorder which should be treated with medication. Others are adamant that ADHD is a social construct in which children, who have suffered developmental trauma, are medicalised. Evolutionary science may help us find a solution to this dichotomy by seeing ADHD as an example of an evolutionary mismatch in which children with ADHD are caught in a school environment that does not suit their natures. By considering how to improve the 'goodness of fit' between the child and their environment, clinicians can be more flexible in finding solutions that are ethically sound.

Attention-deficit/hyperactivity disorder in youth with psychosis spectrum symptoms

BACKGROUND

Childhood attention deficit-hyperactivity disorder (ADHD) is common in psychotic disorders. However, prevalence estimates vary widely and the impact of ADHD on the severity of psychotic symptoms and associated features is unclear. We used the Philadelphia Neurodevelopmental Cohort (PNC; n = 9498 youth age 8-21), which includes a comprehensive structured interview of clinical symptoms and the Penn Computerized Neurocognitive Battery (CNB), to clarify the prevalence of ADHD in psychosis spectrum (PS) youth and determine if comorbid ADHD is associated with severity of psychotic symptoms and cognitive impairment.

METHODS

Prevalence of ADHD among PS youth was established by comparing PS youth to all other youth in the PNC cohort. Cognition was compared between four groups: typically developing (TD), ADHD, PS without ADHD (PS-ADHD), and PS with ADHD (PS+ADHD). To evaluate the impact of ADHD on psychosis symptomatology, severity of positive and negative psychotic symptoms was compared between PS-ADHD and PS+ADHD groups.

RESULTS

ADHD was more prevalent in PS youth compared to non-PS youth (45% vs. 20%). Cognition was significantly impaired in PS youth compared to TD youth, but the presence of ADHD in PS youth was not associated with greater cognitive impairment. Co-morbid ADHD was, however, associated with more severe psychosis symptoms in PS youth.

CONCLUSION

ADHD is more common among PS youth compared to youth without PS symptoms and is associated with more severe psychotic symptoms, but not severity of cognitive impairment. The association between ADHD and psychotic disorders may be mediated by psychosis symptoms in youth and may manifest a more stable cognitive impairment.

Genetics on the neurodiversity spectrum: Genetic, phenotypic and endophenotypic continua in autism and ADHD

How we ought to diagnose, categorise and respond to spectrum disabilities such as autism and Attention Deficit/Hyperactivity Disorder (ADHD) is a topic of lively debate. The heterogeneity associated with ADHD and autism is described as falling on various continua of behavioural, neural, and genetic difference. These continua are varyingly described either as extending into the general population, or as being continua within a given disorder demarcation. Moreover, the interrelationships of these continua are likewise often vague and subject to diverse interpretations. In this paper, I explore geneticists' and self-advocates' perspectives concerning autism and ADHD as continua. These diagnoses are overwhelmingly analysed as falling on a continuum or continua of underlying traits, which supports the notion of "the neurodiversity spectrum", i.e., a broader swath of human neural and behavioural diversity on which some concentrations of different functioning are diagnosed. I offer a taxonomy of conceptions of the genetic, phenotypic, and endophenotypic dimensionality within and beyond these diagnostic categories, and suggest that the spectrum of neurodiversity is characteristically endophenotypic.

Inattention, hyperactivity/impulsivity, and academic competence: Findings from three cohorts

BACKGROUND

Attention-deficit hyperactivity disorder (ADHD) is a risk for learning. Because ADHD commonly includes behaviours of inattention and behaviours of hyperactivity/impulsivity, how the two types of behaviours independently affect children's academic competence remains poorly understood.

AIMS

To investigate the impact of behaviours of inattention and behaviours of hyperactivity/impulsivity on Chinese students' academic competence.

SAMPLES

Parents of 167 preschoolers (Cohort 1), parents of 313 first graders (Cohort 2), and 1,003 high school students (Cohort 3).

METHODS

The ADHD-RS-IV Preschool version (Cohort 1), ADHD-RS-IV Home version (Cohort 2), and BASC-SRP (Cohort 3) were used to measure behaviours of inattention and hyperactivity/impulsivity. Academic competence was operationalized as school readiness (Cohort 1), math and language arts scores at two time points provided by school (Cohort 2), and self-reported academic performance (Cohort 3). Multiple regressions were performed to investigate the relationship between academic performance and behaviours of inattention alone (Step 1), and behaviours of hyperactivity/impulsivity alone (Step 2), and behaviours of inattention together with behaviours of hyperactivity/impulsivity (Step 3).

RESULTS

For each cohort, both types of behaviours were negatively correlated with academic competence. However, regression analyses showed that in Step 3, behaviours of hyperactivity/impulsivity either failed to predict academic competence or predicted better academic competence. Overall, behaviours of inattention alone accounted for a similar amount of variance in academic competence as did behaviours of inattention and hyperactivity/impulsivity combined.

CONCLUSIONS

Behaviours of inattention presented a risk for academic competence but the effect of behaviours of hyperactivity/impulsivity varied. Implications for instructional strategies for behaviours of inattention were discussed.

Racial Disparities in Diagnosis of Attention-Deficit/Hyperactivity Disorder in a US National Birth Cohort

IMPORTANCE

There are limited data on the racial disparities in the incidence of attention-deficit/hyperactivity disorder (ADHD) diagnosis in children at the national level.

OBJECTIVE

To explore differences in rates of diagnosis of ADHD and use of treatment among children by race and ethnicity.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study assessed insurance claims data of children born in the US between January 1, 2006, and December 31, 2012, who had continuous insurance coverage for at least 4 years. The last date of follow-up included in the cohort was June 30, 2019. Race/ethnicity designations were based on self-report and included non-Hispanic White, Black, Hispanic, and Asian. Data were analyzed between October 2019 and December 2020.

EXPOSURES

Race and ethnicity.

MAIN OUTCOMES AND MEASURES

ADHD diagnosis as defined by International Classification of Diseases codes (ninth or tenth editions) and treatment within 1 year of diagnosis, including medication and behavior therapy as defined by billing codes. Data on ADHD diagnosis and treatment were adjusted for sex, region, and household income in a multivariate Cox regression model.

RESULTS

Among 238 011 children in the cohort (116 093 [48.8%] girls; 15 183 [6.7%] Asian, 14 792 [6.2%] Black, 23 358 [9.8%] Hispanic, and 173 082 [72.7%] White children), 11 401 (4.8%) were diagnosed with ADHD. The cumulative incidence at age 12 was 13.12% (95% CI, 12.79%-13.46%). In multivariate Cox regression adjusting for sex, region, and household income, the hazard ratio for Asian children was 0.48 (95% CI, 0.43-0.53); Black children, 0.83 (95% CI, 0.77-0.90); and Hispanic children, 0.77 (95% CI, 0.72, 0.82) compared with White children. In the first year after diagnosis, 516 preschool children (19.4%) received behavioral therapy only, 860 (32.4%) had medications only, 505 (19.0%) had both, and 774 (29.2%) had no claims associated with either option. A higher percentage of school-aged children (2904 [65.6%]) were prescribed medications, and fewer had therapy only (639 [14.4%]) or no treatment at all (884 [20.0%]). Compared with other groups, White children were more likely to receive some kind of treatment. Asian children had the highest odds of receiving no treatment (odds ratio compared with White children, 0.54; 95% CI, 0.42-0.70).

CONCLUSIONS AND RELEVANCE

Racial and ethnic disparities in the diagnosis and treatment of ADHD are evident. Future study is needed to elucidate the mechanism behind these disparities, with special attention to Asian children. Clinicians should provide racially sensitive care in the evaluation and treatment of ADHD.

What children and young people learn about ADHD from youth information books: A text analysis of nine books on ADHD available in Dutch

Attention Deficit Hyperactivity Disorder (ADHD) is not a singular concept. For the purposes of this study, understandings of ADHD are assumed also to spread along a conceptual dimension that includes some combination of biomedical and psychosocial knowledge. Biomedically, ADHD may be considered a somatic affliction causing inattention and hyperactivity, amenable to pharmaceutical treatment. Psychosocially, ADHD ranks among adverse behaviour patterns that are amenable to psychosocial and pedagogical intervention. Considering both biomedical and psychosocial factors are associated with the ADHD construct, it seems self-evident that young people should be offered information that gives equal consideration to both ways of addressing ADHD, but the question is just how balanced the information available to young people is. This study investigated nine information books on ADHD available in the Netherlands in Dutch, aimed at children and young people up to age 17. Thirteen perspective-dependent text elements were identified in qualitative content analysis. Eight attributes associate with a biomedical view: ADHD as cause, biological factors, clinical diagnosis, brain abnormality, medication, neurofeedback, heritability and persistence. Five text elements associate with a psychosocial view: ADHD as perceived behaviour, environmental factors, descriptive diagnosis, behavioural intervention and normalisation. The most frequent text passages encountered describe ADHD as a brain abnormality, along with medical and behavioural treatment. Providing the main focus for information in eight out of nine books, biomedical information about ADHD predominates in the available youth information books, while psychosocial information about ADHD is far less well covered.

Increased Alopecia Areata Risk in Children with Attention-Deficit/Hyperactivity Disorder and the Impact of Methylphenidate Use: A Nationwide Population-Based Cohort Study

Alopecia areata (AA) is an autoimmune disease that causes sudden hair loss. Although few studies have reported the association between AA and attention-deficit/hyperactivity disorder (ADHD), the impact of methylphenidate (MPH) on AA has not been examined. This study examined whether AA risk is higher in children with ADHD than in those without ADHD as well as the impact of MPH use on AA risk in children with ADHD. From the Taiwan Maternal and Child Health Database, we enrolled all 1,750,456 newborns from 2004 to 2017 in Taiwan. Of them, 90,016 children received a diagnosis of ADHD whereas the remaining 1,660,440 did not. To compare AA risk in ADHD and the impact of MPH treatment on it, multiple Cox regression with adjustments for covariates (i.e., age, sex, and psychiatric comorbidities) was performed. The results indicated that 88 (0.098%) children with ADHD and 1191 (0.072%) children without ADHD had AA. Nevertheless, after adjustment for the covariates, AA risk was higher in children with ADHD than in those without ADHD (adjusted hazard ratio [aHR]: 1.30, 95% confidence interval [CI]: 1.04–1.64). Our data indicated a considerable reduction in AA risk (aHR: 0.64) among children with ADHD who received MPH than among those who did not receive MPH; however, this difference was nonsignificant, indicated by a wide 95% CI (0.32–1.25). In conclusion, ADHD and AA may share some underlying mechanisms.

Failure of Healthcare Provision for Attention-Deficit/Hyperactivity Disorder in the United Kingdom: A Consensus Statement

Background: Despite evidence-based national guidelines for ADHD in the United Kingdom (UK), ADHD is under-identified, under-diagnosed, and under-treated. Many seeking help for ADHD face prejudice, long waiting lists, and patchy or unavailable services, and are turning to service-user support groups and/or private healthcare for help. Methods: A group of UK experts representing clinical and healthcare providers from public and private healthcare, academia, ADHD patient groups, educational, and occupational specialists, met to discuss shortfalls in ADHD service provision in the UK. Discussions explored causes of under-diagnosis, examined biases operating across referral, diagnosis and treatment, together with recommendations for resolving these matters. Results: Cultural and structural barriers operate at all levels of the healthcare system, resulting in a de-prioritization of ADHD. Services for ADHD are insufficient in many regions, and problems with service provision have intensified as a result of the response to the COVID-19 pandemic. Research has established a range of adverse outcomes of untreated ADHD, and associated long-term personal, social, health and economic costs are high. The consensus group called for training of professionals who come into contact with people with ADHD, increased funding, commissioning and monitoring to improve service provision, and streamlined communication between health services to support better outcomes for people with ADHD. Conclusions: Evidence-based national clinical guidelines for ADHD are not being met. People with ADHD should have access to healthcare free from discrimination, and in line with their legal rights. UK Governments and clinical and regulatory bodies must act urgently on this important public health issue.

Attention-deficit hyperactivity disorder in school-age children in Gaborone, Botswana: Comorbidity and risk factors

Background

Attention deficit hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders in children. Its occurrence and pattern of presentation are unknown in Botswana.

Aim

To determine the prevalence of attention-deficit hyperactivity disorder (ADHD), associated comorbid conditions and risk factors amongst school-age children in Botswana.

Setting

Primary schools in Gaborone, Botswana.

Methods

This study used a cross-sectional design. A two-stage random sampling technique was utilised to select learners from 25 out of the 29 public schools in the city. The Vanderbilt ADHD Diagnostic Rating Scale (VADRS), teacher and parent versions, was administered.

Results

Of the 1737 children, 50.9% (n = 884) were male, and their mean age was 9.53 years (s.d. = 1.97). The prevalence of ADHD was 12.3% (n = 213). The most prevalent presentation was the predominantly inattentive, 7.2% (n = 125). A family history of mental illness (odds ratio [OR] = 6.59, 95% CI: 1.36–32.0) and perinatal complications (OR = 2.16, 95% CI: 1.08–4.29) emerged as the independent predictors of ADHD.

Conclusions

The prevalence of ADHD in Botswana is slightly higher than that reported in the literature, but the pattern of presentations and comorbidities is similar. A positive family history of mental illness and perinatal complications independently predicted ADHD. Mental health screening amongst families of the affected individuals and improved perinatal care should be considered as health care priorities in Botswana.

Sex Differences in the Meaning of Parent and Teacher Ratings of ADHD Behaviors: An Observational Study

Objective: To test explanations for the underrecognition of female ADHD by examining differences in adult ratings of boys and girls matched for levels of directly observed ADHD behaviors. Method: In a secondary analysis of a population-based sample, 3- to 4-year-olds (n = 153, 79 male) and 8- to 9-year-olds (n = 144, 75 male) were grouped according to levels of directly observed ADHD behaviors (low/moderate/high). Groups were then compared with parent/teacher ADHD ratings. Results: There were no sex differences in levels of directly observed ADHD behaviors within groups. For preschoolers, parents' ratings of males, but not females, significantly increased across groups-mirroring levels of observed behaviors. For older children, both parent and teacher mean ratings were significantly higher for males than females across groups. Conclusion: Identified differences in adult ratings of males and females matched for directly observed behaviors may contribute to understanding the substantial ADHD underrecognition in females.

Behaviors of ADHD and Peer Relationship Difficulties in Chinese and American Youths: Role of Co-Occurring Behaviors of Depression and Anxiety

The co-occurrence of behaviors of attention-deficit/hyperactivity disorder (ADHD) with behaviors of anxiety or behaviors of depression is the norm, but little is known on how the co-occurrence accounted for youths' peer relations. The authors report results on difficult peer relations in relation to behaviors of ADHD, co-occurring behaviors of depression, and behaviors of anxiety from three studies on 862 youths in China and in the United States. Study 1 included 313 ethnically and socioeconomically diverse American youths; Study 2 included 250 youths who were adopted out of Chinese orphanages by American parents; and Study 3 included 299 youths from Beijing, China. Data on difficult peer relations and behaviors of ADHD, depression, and anxiety were collected with the third edition of Behavior Assessment System for Children-Self Report of Personality. In all three studies, each type of problems alone significantly predicted difficult peer relations, but behaviors of ADHD were not significant when co-occurring behaviors of depression or co-occurring behaviors of anxiety were considered. Despite that the youths in our study had different cultural and personal backgrounds, there was no evidence that behaviors of ADHD were detrimental to youths' peer relations when behaviors of depression or anxiety were considered. Implications for intervention were discussed.

Challenges in ADHD care for ethnic minority children: A review of the current literature

While attention deficit hyperactivity disorder (ADHD) has been extensively studied in the past decades, the role of social and cultural practices in its assessment, diagnosis, and treatment has been often overlooked. This selective review provides an overview of research that explores social and cultural influences on help-seeking behavior in ethnic minority children with ADHD. Studies were selected that address cultural diversity in three areas of ADHD help-seeking: problem recognition, access to mental health services, and treatment. Special attention was given to studies of treatment selection and adherence in minority groups. Findings suggested that cultural disparities in ADHD care among ethnic minority children occur in the early stages of problem recognition, through service selection, and in the quality of treatment. Ethnic minority children were less likely than their nonminority counterparts to be diagnosed with ADHD and its comorbid conditions and less likely to be prescribed and adhere to stimulant drug treatment. These differences reflect cultural diversity in norms and attitudes towards mental health issues (e.g., fear of social stigma) as well as limited access to qualified health care. Paradoxically, cultural, racial, and language bias may also lead to the overidentification of ethnic minority children as disabled and to higher ratings of ADHD symptoms. This review highlights the importance of sociocultural factors in understanding developmental psychopathology and help-seeking behavior. In addition, it further supports calls for increasing cultural competence in communications during clinical assessment, diagnosis, and treatment in minority communities. Clinical, theoretical, and methodological considerations for future research are discussed.

Investigative interviewing of youth with ADHD - recommendations for detective training

Attention deficit hyperactivity disorder (ADHD) in youth can lead to a trajectory of early and repeated contact with the criminal justice system (CJS), where such youth face significant challenges due to the nature of their diagnosis and the lack of specialized detective training in this area. This article reviews Australian detectives' perceptions regarding contact with ADHD-affected youth, ongoing contact of such youth with the CJS, and the impact of ADHD on interviewing time efficiency and quality of information gathered. It explores detectives' perceived impact of ADHD on components of the Cognitive Interview (CI). It overviews detectives' perceptions regarding their own skill/ability, training availability and future training preferences regarding the interviewing of ADHD-affected youth. The authors highlight best practice in specialized detective training, as well as in working with ADHD-affected youth. Recommendations are made regarding the design features of a potential specialized training programme for detectives interviewing ADHD-affected youth.

Suggestive diagnosis of attention-deficit/hyperactivity disorder in indigenous children and adolescents from the Brazilian Amazon

The prevalence of attention-deficit/hyperactivity disorder (ADHD) symptoms has been scarcely studied in indigenous cultures that preserve ancestral cultural characteristics. The objective of the study is to estimate the prevalence of suggestive diagnosis of ADHD among indigenous children and adolescents from villages in the Amazon. This is an analytical cross-sectional study using instruments to track ADHD symptoms (the Child Behaviour Checklist for ages 6-18: CBCL/6-18 and the teacher report form for ages 6-18: TRF/6-18) and to investigate their negative impact on the patients (using the Strengths and Difficulties Questionnaire-SDQ). The prevalence of a suggestive ADHD diagnosis according to the CBCL/TRF DSM-IV ADHD subscale without and with negative impact as assessed by the SDQ was 4.3% and 1.1%, respectively. Comorbid oppositional-defiant, conduct problems and anxious symptoms were present in all cases screening positive for ADHD. We also presented a case report as an illustration of the observed clinical presentation. ADHD is a recognizable disorder even in a culture that preserves millennial characteristics. Furthermore, the presence of ADHD symptoms was associated with significant impairment.

Liberating parents from guilt: a grounded theory study of parents' internet communities for the recognition of ADHD

PURPOSE

This study presents a qualitative analysis of information posted on the Internet by two communities of French parents promoting the recognition of ADHD in the context of current health and school practices.

METHOD

Grounded Theory (Strauss & Corbin's approach) was applied to the posted messages, with the aim to discover the main concern and common theme through a constant comparison analysis.

RESULTS

Liberating parents from feeling responsible for their child's misconduct was found to be the core category. From this perspective, we account for the commitment of the digital communities to formalize the child's conduct as a consequence of a neurodevelopmental disorder. This approach helps to account for the promotion of behavioural expertise and conditioning strategies (e.g., positive reinforcement) for handling the child's so-called disorder as appropriate parental responses. Giving evidence for parenting struggles was the third main concern of the communities, in the face of perceived skepticism from professionals towards ADHD as a medical condition.

CONCLUSIONS

By using examples from countries that are found to have a more pro-medical approach to ADHD, the communities aim at improving such medical practices in France. Issues surrounding the claim that ADHD would require a specific style of parenting are also discussed.

The Conners 3-short forms: Evaluating the adequacy of brief versions to assess ADHD symptoms and related problems

The Conners' Rating Scales are widely used to assess attention deficit/hyperactivity disorder (ADHD) and related difficulties in children and adolescents. A short form of the scales is available, which, along with the several advantages of brief versions, also displays good psychometric properties. Nonetheless, no studies have confirmed them in cultural contexts different from the original one. The present study examined the psychometric properties of the Self-Report, Parent, and Teacher Conners 3-Short Forms in terms of reliability and validity in an Italian sample. Analyses were performed on 591 children and adolescents, 631 parents' ratings, and 325 teachers' ratings. To test for discriminative validity, ADHD clinical samples of 55 youth, 63 parents, and 15 teachers were compared to gender- and age-matched groups. Findings confirmed the original multidimensional structures and supported the Conners 3-Short Form scales as reliable and valid tools to assess ADHD and its main comorbid conditions.

Exploring attentive task-based connectivity for screening attention deficit/hyperactivity disorder children: a functional near-infrared spectroscopy study

Connectivity impairment has frequently been associated with the pathophysiology of attention-deficit/hyperactivity disorder (ADHD). Although the connectivity of the resting state has mainly been studied, we expect the transition between baseline and task may also be impaired in ADHD children. Twenty-three typically developing (i.e., control) and 36 disordered (ADHD and autism-comorbid ADHD) children were subjected to connectivity analysis. Specifically, they performed an attention task, visual oddball, while their brains were measured by functional near-infrared spectroscopy. The results of the measurements revealed three key findings. First, the control group maintained attentive connectivity, even in the baseline interval. Meanwhile, the disordered group showed enhanced bilateral intra- and interhemispheric connectivities while performing the task. However, right intrahemispheric connectivity was found to be weaker than those for the control group. Second, connectivity and activation characteristics might not be positively correlated with each other. In our previous results, disordered children lacked activation in the right middle frontal gyrus. However, within region connectivity of the right middle frontal gyrus was relatively strong in the baseline interval and significantly increased in the task interval. Third, the connectivity-based biomarker performed better than the activation-based biomarker in terms of screening. Activation and connectivity features were independently optimized and cross validated to obtain the best performing threshold-based classifier. The effectiveness of connectivity features, which brought significantly higher training accuracy than the optimum activation features, was confirmed (88% versus 76%). The optimum screening features were characterized by two trends: (1) strong connectivities of right frontal, left frontal, and left parietal lobes and (2) weak connectivities of left frontal, left parietal, and right parietal lobes in the control group. We conclude that the attentive task-based connectivity effectively shows the difference between control and disordered children and may represent pathological characteristics to be feasibly implemented as a supporting tool for clinical screening.

A pilot study: Use of the Adult Attention-Deficit/Hyperactivity Disorder Self-Report Scale in a South African patient population

BACKGROUND

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder which typically presents in childhood. This diagnosis may often be overlooked in adulthood, particularly in psychiatric populations. The Adult ADHD Self-Report Scale (ASRS) is an internationally used and reliable screener; however, studies investigating its use in African populations are limited.

AIM

To investigate the application of the ASRS in a South African setting.

SETTING

A patient population in Port Elizabeth, South Africa, was identified as representing a developing or low- and middle-income country population.

METHODS

A convenience sample of acutely presenting psychiatric participants admitted for stabilisation was used. Fieldworkers administered the ASRS; collected information relating to demographics, differential diagnoses, substance use disorder (SUD) presence and substance consumption; and prescribed medication relating to current or historical treatment of ADHD.

RESULTS

The study sample included 30 participants, with black people representing the majority of participants. Adult ADHD Self-Report Scale completion revealed the rate of ADHD within the study population to be 43.3%, a contrast to the initially presumed prevalence of 6.7% which was based on reported methylphenidate therapy. A difference in SUD prevalence was identified between subjects screening positively and negatively for ADHD with a greater tendency towards SUDs seen for ASRS-positive individuals. Significant differences were identified in relation to cannabis- and polysubstance use for ASRS-positive individuals.

CONCLUSION

Despite limitations related to the sample used and challenges in ASRS administration, investigation findings support recommendations for ADHD screening inclusion in acute inpatient settings in South Africa and ASRS translation into indigenous African languages.

The powerless or the empowered? Stakeholders' experiences of diagnosis and treatment for attention-deficit hyperactivity disorder in Ireland

IntroductionIn Ireland, attention-deficit hyperactivity disorder (ADHD) is the most commonly diagnosed condition in Child and Adolescent Mental Health Services (CAMHS). However, little is known about the experiences of stakeholders affected by ADHD in their pathways through care, especially in Ireland.

OBJECTIVES

The aim of this stakeholder voice study was to explore stress and coping among parents and Children and Young People (C/YP) affected by ADHD in an Irish context, in order to contribute to knowledge about what works and what needs to change in practice from a service user perspective.

METHODS

In total, 15 C/YP (7-18 years) with ADHD and their parents participated in semi-structured interviews, which were triangulated using other sources (e.g. visual methods), to contribute to a highly contextualised understanding of lived experiences. Transcribed interviews were analysed using a deductive approach to Thematic Analysis informed by a theoretical framework of stress and coping theory and Bronfenbrenner's bio-ecological model.

RESULTS

Some degree of difficulty in their pathway through care was identified by participants in all case studies. Findings identified barriers to diagnosis, including delays in diagnosis, such as scepticism, stigma, and label avoidance from gatekeepers; poor multiagency working; and misdiagnosis. Once received, diagnosis may serve as an access to empowerment, providing knowledge, understanding, and support. However, C/YP and their parents also reported distressing experiences and a sense of powerlessness within CAMHS and with treatment; such as tensions around medical management, stigma, and a lack of child- and family-centred practice.

CONCLUSIONS

Despite the professionals and the systematic supports available, stakeholders did not feel that they were fully understood, listened to, or participants in accessing diagnosis and care planning.

A systematic review of mindfulness based interventions for children and young people with ADHD and their parents

Objective

Attention deficit hyperactivity disorder (ADHD) is one of the most prevalent disorders in childhood, which may pose risks in later life such as academic underachievement and anti-social behaviour. It has been suggested that mindfulness-based interventions (MBI) may contribute to positive outcomes with child and adult populations. In this article, we aim to systematically review the literature regarding the effectiveness of MBI on both children with ADHD and their parents.

Method

Seven databases were searched using the PRISMA criteria and included peer-reviewed journals and grey literature.

Results

Ten studies met the inclusion criteria. Findings suggested that MBI had positive results in addressing attention deficits in children with ADHD, but in terms of hyperactivity, the evidence was conflicting. MBI interventions also appear to effectively address parental stress and family functioning. However, the rating from the quality assessment showed several methodological limitations.

Discussion

The current evidence on the impact of MBI on ADHD symptoms is non-conclusive. However, promising data indicated the potential for MBI in addressing parental stress and family functioning. Further research is recommended to overcome the current methodological limitations.

ADHD and Gender: subjective experiences of children in Chile

Abstract Although research on ADHD has tended to ignore gender differentials, recent contributions produced mainly from epidemiology have revealed that this diagnostic category seems to be strongly related to gender. However, these contributions seem to limit their scope to the study of the symptoms as well as cognitive, affective and social functioning of children, leaving aside subjective aspects associated with the ADHD practices of diagnosis and treatment. Thus, this article aims to explore how the gender dimension crosses the subjective experience of children diagnosed with ADHD. Based on open interviews conducted with children between the ages of 7 and 13, we show general trends that articulate gender and characteristics associated with the ADHD diagnosis, while at the same time, with children’s experiences that dislocate such trends. The findings were grouped according to four emerging axes: (1) locations, (2) abilities, (3) approches, (4) interactions. Thus, we will show how the experience of boys and girls is multiple in relation to the diagnosis and it is not possible to be reduced to a gender binary perspective.

Rethinking medicalization: discursive positions of children and their caregivers on the diagnosis and treatment of ADHD in Chile

Abstract The debates around the diagnosis and pharmacological treatment of Attention Deficit and Hyperactivity Disorder (ADHD) have traditionally been approached from the perspective of the “medicalization processes” of children’s behaviour. However, this perspective tends to overlook the meanings of diagnosis and treatment of ADHD for children and their caregivers. The purpose of this article is to describe the discursive positions of children and their caregivers on the diagnosis and treatment of ADHD. In-depth interviews were conducted with seven Chilean children and their caregivers. The material was analysed following the procedures of the discourse structure analysis. A discursive structure was identified that configures four emerging realities: the myth of origin of the child’s behaviour and learning problems; the ambivalences in/of medicalization; the process of identity (dis)stabilization under diagnosis and treatment; and the subversion of medicalization. It is observed that the subjective experience of the diagnosis and treatment of ADHD is not homogeneous, since different discursive positions, family and institutional understandings that enter into conflict cross it. The experiences of ADHD are shaped by discursive structures that condition the meanings of this experience. The medicalization process is not univocal, but can take different forms and have consequences on children’s experiences and social trajectories.

What Is a Clinically Relevant Improvement in Quality of Life in Adults With ADHD?

OBJECTIVE

To estimate a minimal clinically important difference (MCID) on the adult ADHD Quality of Life (AAQoL) scale.

METHOD

The MCID was determined from data from short-term ( N = 537) and long-term ( N = 440), placebo-controlled atomoxetine trials in adults with ADHD. For the anchor-based approach, change in clinician-rated Clinical Global Impressions-ADHD-Severity (CGI-ADHD-S) scores was used to derive MCID. For the distribution-based approach, baseline-to-endpoint mean ( SD) changes in AAQoL scores corresponding to 0.5 SD were computed.

RESULTS

The MCID was similar (approximately 8-point difference) between the short-term and the long-term treatment groups when either the anchor-based or distribution-based approach was used.

CONCLUSION

These results suggest that approximately 8 points in the change from baseline on the AAQoL is a MCID.

Screen media use and ADHD-related behaviors: Four decades of research

The diagnosis of attention-deficit/hyperactivity disorder (ADHD) among children and adolescents has increased considerably over the past decades. Scholars and health professionals alike have expressed concern about the role of screen media in the rise in ADHD diagnosis. However, the extent to which screen media use and ADHD are linked remains a point of debate. To understand the current state of the field and, ultimately, move the field forward, we provide a systematic review of the literature on the relationship between children and adolescents' screen media use and ADHD-related behaviors (i.e., attention problems, hyperactivity, and impulsivity). Using the Differential Susceptibility to Media effects Model as a theoretical lens, we systematically organize the existing literature, identify potential shortcomings in this literature, and provide directions for future research. The available evidence suggests a statistically small relationship between media and ADHD-related behaviors. Evidence also suggests that individual child differences, such as gender and trait aggression, may moderate this relationship. There is a clear need for future research that investigates causality, underlying mechanisms, and differential susceptibility to the effects of screen media use on ADHD-related behaviors. It is only through a richer empirical body that we will be able to fully understand the media-ADHD relationship.

ADHD prevalence estimates in Italian children and adolescents: a methodological issue

BACKGROUND

Attention deficit hyperactivity disorder (ADHD) is recognized as the most common, and most studied, developmental age disorder. Basic information, such as the most appropriate case definition and the best way to evaluate the disorder's prevalence rate, however, remains an open issue.

METHODS

A comprehensive meta-analysis on the epidemiology of ADHD in Italy, which was lacking from the literature, was therefore performed to attempt to estimate the actual prevalence rate of ADHD, highlighting conceptual and quantitative differences between clinical-diagnosis and survey-based symptoms studies. The Medline, Embase, and PsycINFO databases, and the grey literature, were searched up to January 2018. The review was laid out in three main sections: an overall prevalence estimate, an epidemiological profile of ADHD symptoms, and an attempt to define the actual rate of ADHD diagnosis, as emerged from Italian studies.

RESULTS

A total of 15 unique studies were included. These contributed to estimating the prevalence of ADHD in 67,838 subjects aged 5-17, representing 9 of the 20 regions (45%) of Italy. Overall, the pooled prevalence of ADHD was 2.9% (range: 1.1-16.7%). When distinguishing studies based on case definition, however, we found an average prevalence estimate, based on symptoms criteria, of 5.9% (range: 1.4 to 16.7%) and a best-estimate prevalence rate of 1.4% (range: 1.1 to 3.1%).

CONCLUSIONS

Following the case definition for epidemiological studies of ADHD, counting only subjects with an ADHD diagnosis performed and confirmed by clinical assessment would reduce the wide variability in prevalence estimates, and, above all, would both describe the real rate of subjects suffering from ADHD disorder and avoid misdiagnosis.

ADHD: science, stigma and service implications

We are delighted to dedicate an edition of the Irish Journal of Psychological Medicine to the topic of attention-deficit hyperactivity disorder (ADHD). ADHD accounts for the majority of clinical presentations to Child and Adolescent Mental Health Services, both in terms of new assessments and ongoing attendances. Papers presented in this edition reflect on the evolving construct of ADHD, drawing from science, clinical practice and public opinion. Current and evidenced-based assessment and treatment practice guidelines are reviewed. International longitudinal studies allow us to understand the personal and societal cost, which can persist for many years post-diagnosis. Despite continuation to adulthood in many young people, follow on adult services are lacking. It is fitting that submissions, by way of personal reflections and opinion pieces, are also included from adult colleagues as they reflect on their experiences in this area. Given the recent development of a national clinical programme in ADHD in Ireland, coupled with a growing evidence for effective interventions, it is hoped that this special edition will highlight the need for appropriate and accessible ADHD treatments across the lifespan.

How evolutionary thinking can help us to understand ADHD

We argue that current debates about attention-deficit hyperactivity disorder (ADHD) can be considered afresh using an evolutionary lens. We show how the symptoms of ADHD can often be considered adaptive to their specific environment. We suggest that, from an evolutionary point of view, ADHD symptoms might be understood to result from an ‘evolutionary mismatch’, in which current environmental demands do not fit with what evolution has prepared us to cope with. For example, in our ancestral environment of evolutionary adaptedness (EEA), children were not expected to sit still and concentrate on academic tasks for many hours a day. Understanding ADHD in terms of such a ‘mismatch’ raises significant issues regarding the management of childhood ADHD, including ethical ones. An approach based on the concept of mismatch could provide an alternative to current debates on whether ADHD results from nature or nurture and whether it is under- or over-diagnosed. It would allow clinicians and policy makers to take both the child and the environment into account and consider what might be desirable and feasible, both in society and for specific children, to lessen the mismatch.

LEARNING OBJECTIVES

How ‘culture bound’ is ‘cultural psychiatry’?

Cultural psychiatry as a clinical specialty sprung mainly from Europe and North America, in order to respond to growing concerns of ethnic minorities in high-income countries. Academic psychiatrists pursuing comparative international studies on mental health, together with medical anthropologists conducting clinical ethnographies, contributed to its theoretical basis (Kleinman, 1987; Littlewood, 1990). What at first appeared to be a marginal specialty is no longer so. For example, the UK alone has witnessed a steady growth of the field, as evidenced by its mandatory inclusion in mental health training curricula, and the existence of several taught masters courses, academic positions in universities and three dedicated journals, as well as, more recently, lead papers in mainstream publications that have debated the cultural position of ‘biology’ itself (Timimi & Taylor, 2004). Additionally, with a proliferation of clinical jobs for ‘ethnic minority’ services in hospital trusts across the country, there is ample scope for employment. The overall evidence indicates that ‘cultural psychiatry’ in the UK is now a specialty in its own right.

Dutch Norms for the Eyberg Child Behavior Inventory: Comparisons with other Western Countries

The Eyberg Child Behavior Inventory (ECBI) is one of the most widely used and well-validated parent rating scales for children's disruptive behavior. This screening instrument is a short, targetted and easy to implement inventory with good psychometric properties and is normed for different countries, among which the United States, Spain, Sweden and Norway. The ECBI has been successfully used for research and clinical purposes, in several countries including The Netherlands. To date, Dutch studies have relied on Scandinavian or US norm scores. However, this may be problematic because of cross-cultural differences in the degree to which certain behaviors are seen as problematic by parents. The main goal of this paper therefore was to obtain norm scores for The Netherlands among 6462 Dutch children aged 4 to 8 years (Mage = 6.37 years; SD = 1.32; 50.6% boys). In line with previous research, we found small differences on the mean sum scores across children of different ages (intensity scale) and gender (intensity and problem scale). Therefore, Dutch norm scores were provided age- and gender specific. Our results showed that disruptive behavior of children in the most rural areas was reported as occurring less frequently and was seen as less problematic by parents compared to the disruptive behavior of children in less rural areas. Finally, we found that Dutch norm scores on the ECBI were significantly lower than US norm scores, and significantly higher on the intensity scale (but not the problem scale) than Norwegian and Swedish norm scores.

La Construcción Social de la Hiperactividad

El trastorno por déficit de atención e hiperactividad (tdah)es una afección frecuente, con alta variabilidad en su preva-lencia a través de contextos, y de interés por la repercusión que tiene sobre el desempeño escolar de quienes la padecen. Se exploraron las construcciones simbólicas que hacen diferentes actores acerca de niños diagnosticados con TDAH. Con tal fin se realizaron entrevistas abiertas de tipo semántico y episódico a 31 participantes bogotanos, distribuidos en grupos de maestros, padres y niños. Estas entrevistas fueron abordadas desde una perspectiva de análisis de discurso. Los resultados mostraron que el tdahse reconstruye, a partir de la perspectiva del observador y del contexto, en términos de problema hereditario y de fallas en las prácticas de crianza. Por su parte, para los niños, el diagnóstico es un evento importante en la construcción de su subjetividad.
