Background: The field's understanding of the association between sluggish cognitive tempo (SCT) and sleep is severely limited by the lack of multi-method and multi-informant research designs that move beyond global ratings, often focused on a limited number of sleep-related domains, such as daytime sleepiness. The current study begins to address…

Objective: To conduct a systematic review of the measures designed to assess sluggish cognitive tempo (SCT) since the first SCT scale using careful test-construction procedures was published in 2009. Methods: The MEDLINE (PubMed), Embase, PsychINFO, and Web of Science databases were searched from September 2009 through December 2019. Articles…

In this editorial perspective we consider the potential conceptual and empirical overlap between the research on mind wandering, particularly in its pathological extreme, and that on sluggish cognitive tempo (SCT) as it has diverged from research on attention-deficit/hyperactivity disorder (ADHD). The more advanced state of research findings on…

Objective: The aim of present research was to make a Meta-Thinking educational program based on mental-brain simulation and to evaluate its effectiveness on executive functions, emotion regulation and impulsivity in children with ADHD. Methods: The research method was Embedded Design: Embedded Experimental Model. The research sample included 32…

Objective: In this review, we examined if there is a deficit in facial recognition of emotion (FER) in children, adolescents, and adults with attention deficit hyperactivity disorder (ADHD). Background: Emotional regulation is impaired in ADHD. Although a facial emotion recognition deficit has been described in this condition, the underlying…

This research aims to develop an instrument for the evaluation of impulsivity traits in children and to examine the psychometric features of the developed scale. The process of developing the scale involved three main phases: namely, item generation, evaluation of content validity, and analysis of psychometric properties. The study sample…

Objective: This study examined the unique and interactive effects of PA volume and within-person fluctuations in PA volume (i.e., intraindividual variability in PA volume; PA-var) on preschoolers' (N = 141; 47.5% girls) ADHD symptoms. Method: Preschoolers wore accelerometers during the school day over a 2-week period. Teachers reported on…

Objective: Maladaptive daydreaming (MD) is characterized by vivid, excessive fantasy activity that becomes prioritized over other activities and may result in avoidant coping strategies. Little is known about the relationship between MD and internalized stigma in the neurodivergent sample. The current study aimed to examine emotional…

The Adult Concentration Inventory (ACI) is an adult self-report measure of sluggish cognitive tempo (SCT) developed following a meta-analysis identifying items distinguishing SCT from ADHD inattention. To date, only one study conducted in college students has examined the structural and external validity of the ACI. The current study evaluated the…

Objective: Sluggish cognitive tempo (SCT) and autistic-like traits (ALTs) may occur together in attention-deficit/hyperactivity disorder (ADHD). This study aimed to explore a possible association between SCT and ALTs in a sample diagnosed with ADHD. Method: A total of 147 children and adolescents with ADHD aged 6 to 14 were included in the study.…

Objective: The QbTest that combines a continuous performance task (CPT) with a motion-tracking system may help identify attention deficit hyperactivity disorder (ADHD). This study examined the structure and diagnostic ability of the QbTest in children and adolescents. Method: Retrospective data from 1,274 children and adolescents were analyzed.…

Objective: To examine the manifestation of cognitive control deficit of children with different levels of hyperactivity, an "at risk" dimension for ADHD. Method: A group of children with high hyperactivity (N = 40) and another group of children with low levels of hyperactivity (N = 38) performed a modified stop-signal anticipation task,…

Children who exhibit inattention (IA) and hyperactivity-impulsivity (HI), symptoms often indicative of attention-deficit/hyperactivity disorder (ADHD), have notable social impairments. We investigated whether IA and HI are directly connected to peer difficulties or indirectly connected through their known association with other problem behaviors.…

Introduction: This study seeks to psychometrically evaluate the inattention and hyperactivity/impulsivity subscales of the Vanderbilt ADHD Teacher Rating Scale (VADTRS) for the diagnosis of Attention Deficit Hyperactivity Disorder (ADHD) in children and adolescents in Chile. Method: The sample included 353 students from the 2nd grade of primary…

Both ADHD and poor sleep are associated with deficits in prefrontal cortex functioning, and related executive processes (e.g. directing attention, judgement and decision-making). The present study examined whether sleep factors provided an indirect link between certain symptoms of ADHD and impulsivity or future orientation among college students.…
