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...

This study aimed to evaluate the utility of a novel, more cost-effective driving simulator, Assetto Corsa (AC), in detecting differences in driving performance between individuals with and without ADHD. Driving simulators are a useful means of assessing driving performance in those with attention-deficit hyperactivity disorder (ADHD); however, they are frequently expensive and thus unavailable to many researchers. A total of 87 participants (16 with ADHD, 71 without) completed an AC driving simulator task. They also completed computerized measures of attention and executive functioning and a questionnaire assessing self-reported driving behaviors and anger, ADHD and related symptoms, and mind wandering...

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...

This study aimed to understand the contributions of active ADHD symptoms and the diagnostic label of ADHD in yielding negative attitudes and social distance ratings. Using Amazon's Mechanical Turk (n = 305), respondents were assigned to read a vignette about: (a) a typically developing child, (b) a child with active ADHD symptoms and (c) a child with active ADHD symptoms + diagnostic label. Participants were then asked to answer questions about their beliefs and feelings about the child in the vignette...

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...

Children with attention-deficit/hyperactivity disorder (ADHD) experience high rates of temperamental negative affect and comorbid internalizing and externalizing pathology. The current study explored the role of emotion-specific regulation in accounting for the link between temperamental negative affect and psychopathology among children with ADHD. Forty parents of children ages 8-11 (N =29 males, N =11 females) completed measures of child temperament, emotion-specific dysregulation (i.e., anger dysregulation, sadness dysregulation), and psychopathology...

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...

This longitudinal study focused on early behavioural problems and autistic traits. In a stratified, population-derived sample of 119 children, mothers reported through questionnaires on externalizing, internalizing, and social-communicative characteristics of their child in infancy (14 months) and toddlerhood (37 months), and on autistic traits at preschool age (4-5 years). Children with consistently normal behaviour from infancy to toddlerhood showed lower autistic traits at preschool age than children with deviant behaviour on one or both time points...

Studies have strongly suggested a disturbed regulation of dopaminergic neurotransmission in attention-deficit/hyperactivity disorder (ADHD) and Parkinson's disease (PD). A genetic and phenotypic overlap between both disorders is discussed. A well-studied risk gene for PD is the gene coding for α-synuclein (SNCA). α-Synuclein, a protein located primarily in the presynaptic vesicles, has been suggested to play a role in the modulation of dopamine transporter (DAT) function. DAT is the target of psychostimulants for the treatment of ADHD and plays a key role in regulating the dopamine concentrations in the synaptic cleft...

Na+ /H+ Exchanger 9 (NHE9) is an endosomal membrane protein encoded by the Solute Carrier 9A, member 9 gene (SLC9A9). SLC9A9 has been implicated in attention deficit hyperactivity disorder (ADHD), autism spectrum disorders (ASDs), epilepsy, multiple sclerosis and cancers. To better understand the function of NHE9 and the effects of disease-associated variants on protein-protein interactions, we conducted a quantitative analysis of the NHE9 interactome using co-immunoprecipitation and isobaric labeling-based quantitative mass spectrometry...

Adult attention-deficit/hyperactivity disorder (aADHD) has recently been better recognized and treated in many European countries. In spite of this development, aADHD still features as a "hidden" comorbidity, often not diagnosed even in patients under psychiatric treatment for other psychiatric disorders. The aim of this study was to establish the prevalence rates of unrecognized aADHD in academic centers providing regular psychiatric services in the Czech Republic and Hungary. In a population of psychiatric in-and outpatients, Adult ADHD Self-Report Scale was administered...
