Executive functioning (EF) training interventions aimed at ADHD-symptom reduction have limited results. However, EF training might only be effective for children with relatively poor EF capacity. This randomized double-blind placebo-controlled study examined whether pre-training EF capacity moderates the outcome of an EF-training intervention on measures of near transfer (EF performance) and far transfer (ADHD symptoms and parent-rated EF behavior) immediately after treatment and at 3-month follow-up. Sixty-one children with ADHD (aged 8-12) were randomized either to an EF-training condition where working memory, inhibition and cognitive flexibility were trained, or to a placebo condition...

Research on motivational processes in attention deficit/hyperactivity disorder (ADHD) focuses on reward. Studies with punishment are limited and findings mixed. This study evaluated the effects of punishment on response allocation in Japanese children with and without ADHD. Thirty-four children meeting DSM-IV criteria for ADHD and 59 typically developing control-group children completed an operant task in which they choose between playing two simultaneously available games. Reward was arranged symmetrically across the games under concurrent variable interval schedules...

Although anxiety and attention-deficit/hyperactivity disorder (ADHD) symptoms are highly comorbid, research has generally examined the executive functioning (EF) deficits associated with each of these symptoms independently. The purpose of this study was to examine the unique and interactive effects of anxiety and ADHD symptoms (first respectively, then collectively) on multiple dimensions of EF (i.e., inhibition, updating, and shifting, respectively). A sample of 142 youth from the community (age range 8-17 years; Mage  = 11...

The aim of the present study was to evaluate relationships of Internet addiction (IA) and Internet gaming disorder (IGD) symptom severities with probable attention deficit/hyperactivity disorder (ADHD) and aggression among university students, while controlling the effects of anxiety and depressive symptoms. The study was conducted with online survey among 1509 volunteered university students in Ankara who regularly use the Internet, among whom we conducted analyses related with IA. Among these students, 987 of them, who play video games, were included in the analyses related with IGD...

Attention-deficit/hyperactivity disorder (ADHD) is a neuropsychiatric disorder normally diagnosed in childhood and persisting into adulthood in up to two-thirds of the patients. Its core symptoms comprise inattention and hyperactive-impulsive behaviours. Several studies suggest that patients with ADHD show alterations in self-regulation and self-monitoring. So far, it has not been described whether these deficits also affect the awareness of one's own bodily signals, that is, interoceptive awareness. To investigate possible alterations in interoceptive awareness, 14 adult patients with ADHD and 16 healthy controls performed a heartbeat detection task, in which they had to count their heartbeat without any external help (e...

Impulsive behaviours occurring as a central deficit in connection with attention-deficit/hyperactivity disorder (ADHD) are associated with social and academic impairment in children. Whereas impulsivity was shown to be related to both delay aversion and deficient timing skills, the mutual relation between the latter two has hardly been investigated. The present study therefore examined the interplay of delay aversion, timing skills, and impulsivity in a sample of eighty-eight children aged between seven and fourteen, twenty-one of them diagnosed with ADHD...

There is a debate how different ADHD cases with a comorbid sluggish cognitive tempo (SCT) phenotype are from subjects with a pure inattentive ADHD presentation (ADHD-restrictive inattentive presentation). In this study, 214 patients aged 8-15 years from an ADHD outpatient clinic were assessed, and 100 typically developing controls (TD) were recruited as comparisons. No psychiatric comorbidities except for oppositional defiant disorder were allowed. We compared 29 cases with ADHD + SCT with 34 ADHD-RI cases and 92 TD subjects on sociodemographic profiles, CBCL subscales scores and neurocognitive findings...

This study examined the psychometric properties, convergent validity, and divergent validity of a Japanese translation of Barkley (The Barkley adult ADHD rating scale-IV, Guilford Press, New York, 2011) rating scale for assessing sluggish cognitive tempo (SCT) in adults. In total, 429 Japanese adults participated across three samples: 26 diagnosed with attention-deficit/hyperactivity disorder (ADHD; ages 19-50), 81 adults without ADHD (ages 22-65), and 322 university students (ages 18-27). All participants completed rating scales of SCT, ADHD, anxiety, and depressive symptoms...

Emerging research has identified sluggish cognitive tempo (SCT) as a construct separate from ADHD predominately inattentive presentation. The present study explores the longitudinal stability of SCT over a period of 7 years, specifically the independent effects of SCT on behavioural and academic outcomes concurrently over a 3-year period. A sample of 639 twins, aged 6-12 years, participating in the Western Reserve Reading and Math Project (WRRMP) were assessed at seven annual home visits. The WRRMP sample is an unselected sample of twins representative of the general population of typically developing school-age children...

The association between social anxiety disorder (SAD) and attention-deficit/hyperactivity disorder (ADHD) is poorly established. In fact, increasing and converging evidences suggest that there is a close relationship between the two disorders. High comorbidity rate between these two disorders, follow-up studies showing high rates of later development of SAD in ADHD and treatment studies in which ADHD medications have been helpful for both conditions all indicate this relationship. Recently, we have published a hypothesis regarding the development of SAD secondary to ADHD...

There is sparse research on quality of life (QoL) as an outcome measure in patients with substance use disorders (SUD), with or without attention deficit hyperactivity disorder (ADHD). We aimed to investigate whether SUD patients with and without ADHD (SUD + ADHD vs. SUD - ADHD) differed in QoL at baseline and at a 12-month follow-up after SUD treatment. The groups were additionally compared with data from a national population sample (NPS). From a sample of 16 SUD + ADHD and 87 SUD - ADHD patients originally recruited between 2010 and 2012, eight SUD + ADHD (50...

This study examines how ADHD-related symptoms and impairments interact to predict depression symptoms in young adolescents with ADHD. A sample of 342 adolescents (71% male, mean age = 13 years old) with DSM-IV-TR diagnosed ADHD completed baseline clinical assessments upon entry to a psychosocial treatment study for ADHD. Ratings of ADHD and sluggish cognitive tempo (SCT) symptoms, and social and academic impairment were obtained from parents, while ratings of depressive symptoms and conflict with parents were obtained from youth...

In recent years, there has been an increasing focus on the role of future expectations-the extent to which a future outcome is deemed likely-in the health and well-being of adolescents, with research linking future expectations to outcomes such as an increased likelihood of engaging in risky health behaviors. As yet, however, there has been no research on future expectations and attention deficit/hyperactivity disorder (ADHD) in adolescence. To address this research gap, the current study examined the association between ADHD symptoms/possible ADHD status and future expectations in a school-based sample of adolescents...

In the present study, our primary aim was to compare the generalized social anxiety (GSAD) patients with and without attention-deficit/hyperactivity disorder (ADHD) in terms of avoidant personality disorder (AVPD), and some clinical variables. We also investigated the relationship of AVPD and depression with ADHD and GSAD. We hypothesized that ADHD may be associated with AVPD in patients with GSAD. Seventy-six patients with GSAD were evaluated for depression, AVPD, and childhood and adulthood diagnoses of ADHD...

Guidance on management of attention deficit hyperactivity disorder (ADHD) in the UK was issued by the National Institute for Clinical Excellence in 2008. No UK study has examined all psychotropic prescribing in young people with ADHD since the introduction of the guidance; this is especially relevant due to the high prevalence of psychiatric comorbidity in this population. The aim of this study was to describe primary care prescribing of ADHD and other psychotropic medications for young people with ADHD...

The use of medicines to treat attention deficit/hyperactivity disorder (ADHD) has increased worldwide, including the use of amphetamine-based medicines or prodrugs that metabolise to amphetamine in vivo. At the same time, drugs-of-abuse testing by non-specific, point-of-care immunoassay methods ('quick tests') has increased. This article discusses the risk of 'false positive' results or post-analytical misinterpretations of results when immunoassays are used to analyse biological samples from ADHD patients...

Although there is limited knowledge about early signs of ADHD, deviations in motor development are suggested as a possible indicator of such early signs. The purpose of the present systematic review was to gather knowledge about motor development before three years of age in children later diagnosed with ADHD. A systematic search was completed in four research databases, and the quality of the identified studies was systematically assessed. Of 440 initial search results, only five studies met the inclusion criteria and were fully abstracted...

Attention-deficit hyperactivity disorder (ADHD) is frequently associated with language impairment, autism spectrum disorder (ASD) symptoms and higher-order language deficit (HOLD); yet, their complex relationship is poorly understood. HOLD encompasses deficits in using language for reasoning, problem-solving, causal and critical thinking. This study evaluates the roles of HOLD in children with ADHD. We hypothesise that both our subgroups (ADHD-only and ADHD + 'ASD traits') will have HOLD difficulties, though to a differing degree, as children with ADHD are compromised by executive function deficits, and those with additional ASD traits are further impaired by pragmatic language deficits...
