Abstract
OBJECTIVE The study aims to examine family functionality, emotion regulation difficulties, preference for loneliness, social exclusion, internalizing and externalizing disorders, and executive functions in children with Attention Deficit Hyperactivity Disorder (ADHD) and Cognitive Disengagement Syndrome (CDS) and compare with ADHD, and ADHD+ Oppositional Defiant Disorder (ODD). METHOD This study included 842 children aged 8-12 years. The subjects were categorized according to DSM-V as ADHD (n = 246), ADHD + ODD (n = 212), ADHD + CDS (n = 176), and Control group (n = 207). The solitude and social exclusion, difficulties in emotion dysregulation and Barkley SCT scales, Child Behavior Checklist, family assessment device, and Central Vital Signs (CNSVS) test were used. RESULTS According to the study, children with ADHD + CDS had higher rates of internalizing disorders. They also preferred being alone and experienced more difficulty communicating with their parents and solving problems within the family. Additionally, these children had difficulty recognizing and understanding the emotional reactions of others. The ADHD + ODD group presented a poorer performance on CNSVS domain tests except for the psychomotor speed test than other groups. Also, ADHD + CDS children had the lowest psychomotor speed scores and lower scores on reaction time and cognitive flexibility than pure ADHD children. CONCLUSION This study will contribute to the etiology, treatment, and clinical discrimination of ADHD + CDS.

Abstract
This study aims to investigate the predictive and mediating relationships between emotion dysregulation, internalizing disorders, family functionality, loneliness preference, and executive functions (EF) in children with attention deficit hyperactivity disorder and cognitive disengagement syndrome (ADHD + CDS). This study included 176 children and adolescents (92 boys, 84 girls) who were diagnosed with ADHD + CDS according to the Diagnostic and Statistical Manual of Mental Disorders, the Fifth Edition criteria by a fellowship-trained child and adolescent psychiatrist, between ages 8 -12 (M = 10, SD = 1.52) with a convenience sampling method. The solitude scale for children, difficulties in emotion dysregulation scale, Child Behavior Checklist, Barkley Sluggish Cognitive Tempo Scale, Family assessment device, and CNS Vital Signs test were used. The results showed that difficulty in emotion regulation, preference for loneliness, internalizing disorders and CDS symptom severity did not have a mediating effect between family functionality and EF. Still, emotion dysregulation mediates the relationship between EF and internalizing disorders by itself and through loneliness preference. Also, preference for loneliness and emotion dysregulation had a mediating effect between family functionality and internalizing disorders. Finally, it was found that the effect of emotion regulation difficulty, loneliness preference, and internalizing disorders had a mediating role between CDS symptom severity and family functionality. In conclusion, the information obtained from this study on the etiology of CDS may guide future studies.

Abstract
Given the substantial increase in pediatric obesity rates in recent decades, its long-term stability, and its pervasive negative outcomes, continuous efforts to identify factors that may place children at increased risk for overweight or obesity (OW/OB) are essential. As such, the primary aim of the present investigation was to examine the extent to which symptoms of Cognitive Disengagement Syndrome (CDS; i.e., Sluggish Cognitive Tempo) relates to child body mass index (BMI) independent of Attention-Deficit/Hyperactivity Disorder (ADHD). The study is the first to examine whether CDS subdomains of slowed thinking, hypoarousal, and daydreamy is associated with BMI. Analyses included data from 72 clinically-referred children (46 males, 26 females) aged 4-12 years old (M = 8.41, SD = 2.48). CDS and ADHD were assessed using standardized parent-report rating scales, and children's BMI was collected at the time of encounter. Bayesian hierarchical regression models revealed no evidence that overall CDS symptoms or ADHD symptoms (overall and subdomain) predicted child BMI. However, models did provide moderate evidence that hypoarousal and daydream subdomains jointly predicted BMI independent of ADHD (BF10 = 19.28-21.87). The present study suggests that CDS is a risk factor for obesity in young children and future research is needed to inform clinical interventions and to provide further understanding of the relatively nuanced association between CDS symptoms and obesity.

Abstract
Sluggish cognitive tempo (SCT) (cognitive disengagement syndrome) (CDS) describes a cluster of symptoms including slowness, lethargy, and daydreaming. This study aims to evaluate the psychometric properties of the Turkish version of the Child and Adolescent Behavior Inventory (CABI-SCT) scale and its relationship to other psychological difficulties. A total of 328 children and adolescents aged between 6-18 years were included in the study. CABI-SCT, Revised Child Anxiety and Depression Scale (RCADS), Barkley Child Attention Scale (BCAS), ADHD Rating Scale-IV, and Strengths and Challenges Questionnaire (SDQ) were administered to parents of participants. Reliability analysis demonstrated good internal consistency and reliability. Confirmatory factor analysis indicated that the one-factor model of the Turkish version of CABI-SCT is an acceptable construct. This study supports the validity and reliability of the Turkish version of CABI-SCT for use in children and adolescents providing initial data concerning the psychometric properties and difficulties associated with the Turkish version of the CABI-SCT.

Abstract
Background: There has been a debate on whether sluggish cognitive tempo (SCT) differs from attention-deficit/hyperactivity disorder (ADHD). Although there have been many studies on metabolic parameters in relation to ADHD, no similar studies have been conducted on patients with SCT. We investigated whether there are differences between SCT and ADHD in terms of these factors. Subjects and Methods: Sixty-two participants with ages ranging from 11 to 18 who have diagnosis of ADHD (33 subjects) and SCT (29 subjects) were included in this study. The parents of all participants completed the 48-item Conners' Parent Rating Scale (CPRS) and the Barkley Child Attention Scale (BCAS) forms, and all participants' blood was taken to compare metabolic, oxidative stress, and antioxidant status of the SCT and ADHD groups. A child and adolescent psychiatrist interviewed the parents and children to assess the diagnosis of SCT and ADHD using standard diagnostic procedures. Results: In the comparison between the SCT and ADHD groups in terms of metabolic parameters, statistically significant differences were found in terms of total oxidant status, total antioxidant status, Oxidative Stress Index, total thiol, native thiol, disulfide, interleukin (IL)-1β, IL-6, and DNA damage (p < 0.05), but not in terms of tumor necrosis factor-α (p > 0.05). Conclusions: Our data showed that these two disorders may be different, but we believe that the data that indicate their differences remain inconclusive overall, but this study may be a potential pathway for future research.

RESEARCH IN DEVELOPMENTAL DISABILITIES 2023; 139:104557. [PMID: 37327573 DOI: 10.1016/j.ridd.2023.104557] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 05/14/2023] [Accepted: 06/02/2023] [Indexed: 06/18/2023]
Abstract
BACKGROUND & AIMS The purpose of this study was to examine the relationships between Attention Deficit Hyperactivity Disorder (ADHD), Sluggish Cognitive Tempo (SCT), demographic factors, and Internet Addiction (IA) and internet gaming disorder (IGD) among medical students and resident doctors. METHODS The study included 274 medical students and resident doctors. (Ages:18-35, 70.4% female). Fisher exact test, Contingency Table analyses, Mann Whithey-U Test and structural equation model-path analysis were used for analysis. The Sociodemographic Information Form, ASRS Scale, Barkley SCT Scale, Young Internet Addiction Test-Short Form and The Digital Game Addiction Scale were utilized to collect data. RESULTS In the sample, 48 participants (17.51%, 22 female, 26 male) were classified as having a high-risk internet gaming disorder (IGD+), while 53 participants (19.3%, 37 female, 16 male) were classified as having a high-risk internet addiction (IA+). SCT Scale Daydreaming and Sluggishness scores, as well as ASRS Scale Inattention and Hyperactivity/Impulsivity ratings, were all substantially higher in high-risk groups (for all, p < 0.05). Instead of age, there was no difference between high and low-risk groups, but men had a significantly greater rate of high risk- IGD (%32.1 vs. 11.4; p = 0.001). Path analysis revealed that while older age has a substantial negative effect (β = -0.37, p = 0.001) on increased risk of IA, Inattention (β = 0.19, p = 0.028), Daydreaming (β = 0.62, p0.001), and Sluggishness ( β = 1.12, p0.001) had significant positive effects. On the other hand, results revealed that male gender (β = 5.08, p0.001), IA scores (β = 0.21, p0.001), and only Sluggishness ( = 0.52, p = 0.002), but not Inattention, Hyperactivity/impulsivity, or Daydreaming, have positive effects on greater risk of internet gaming disorder (IGD). CONCLUSION & IMPLICATIONS Our study is the first to show that SCT symptoms increase the risk of Internet addiction and Internet Gaming Disorder even when ADHD symptoms are controlled. To date, many research have highlighted the necessity of ADHD treatment when evaluating IA and IGD. However, SCT symptoms have a greater impact on people who are predisposed to these behavioral addictions, and despite high comorbidity rates, various treatment approaches for ADHD and SCT are effective. SCT should be kept in mind when assessing treatment-resistant individuals with IA and IGD.

J Am Acad Child Adolesc Psychiatry 2023; 62:629-645.

Abstract
OBJECTIVE The aim of this work was 2-fold: (1) to evaluate current knowledge and identify key directions in the study of sluggish cognitive tempo (SCT); and (2) to arrive at a consensus change in terminology for the construct that reflects the current science and may be more acceptable to researchers, clinicians, caregivers, and patients. METHOD An international Work Group was convened that, in early 2021, compiled an online archive of all research studies on SCT and summarized the current state of knowledge, noted methodological issues, and highlighted future directions, and met virtually on 10 occasions in 2021 to discuss these topics and terminology. RESULTS Major progress has been made over the last decade in advancing our understanding of SCT across the following domains of inquiry: construct measurement and stability; genetic, environmental, pathophysiologic, and neuropsychological correlates; comorbid conditions; functional impairments; and psychosocial and medication interventions. Findings across these domains are summarized, and potential avenues to pursue in the next generation of SCT-related research are proposed. Following repeated discussions on terminology, the Work Group selected "cognitive disengagement syndrome" (CDS) to replace "SCT" as the name for this construct. This term was deemed to best satisfy considerations that should apply when selecting terms for a condition or syndrome, as it does not overlap with established terms for other constructs, is not offensive, and reflects the current state of the science. CONCLUSION It is evident that CDS (SCT) has reached the threshold of recognition as a distinct syndrome. Much work remains to further clarify its nature (eg, transdiagnostic factor, separate disorder, diagnostic specifier), etiologies, demographic factors, relations to other psychopathologies, and linkages to specific domains of functional impairment. Investigators are needed with interests and expertise spanning basic, clinical, and translational research to advance our understanding and to improve the lives of individuals with this unique syndrome.

Abstract
Although the study of cognitive disengagement syndrome (CDS; previously called sluggish cognitive tempo) first emerged in the 1980s, very little is known about treating CDS or its impact on evidence-based interventions for attention-deficit/hyperactivity disorder (ADHD) with which it frequently co-occurs. The objective of this leading article was to investigate the existing evidence on medication treatment and CDS, including studies that have examined CDS response to medication and CDS as a moderator of ADHD treatment response. A total of seven studies were identified. At present, the limited existing literature suggests that psychostimulants such as methylphenidate and lisdexamfetamine, as well as atomoxetine, may improve CDS symptoms, although replication and research on related medications is needed. However, there are indications that CDS symptoms may predict a reduced response to methylphenidate in children with ADHD. Although untested, research on the neurobiological, neuropsychological, and behavioral correlates of CDS point to a possible benefit of other ADHD medications (e.g., guanfacine), medications that treat narcolepsy (e.g., modafinil), and medications traditionally used to treat depression and anxiety (e.g., viloxazine, bupropion, fluvoxamine), some of which have also recently been used in ADHD management. The article concludes with recommendations for future research on pharmacologic treatment and CDS.

Abstract
OBJECTIVE Rates of obesity have risen steeply in the western world in all age groups. Sluggish Cognitive Tempo (SCT) is characterized by a cluster of symptoms. Daytime sleepiness, commonly seen in obesity, may share a similar origin with sleepiness and daydreaming symptoms of SCT. This study aims to investigate the relationship between obesity, SCT, daytime sleepiness, and eating habits. METHOD Adolescents, aged between 10-17 years, with a BMI >95th centile, were recruited to the study. Clinical interviews were supplemented with standardized questionnaires. RESULTS Of the 35 adolescents, more than one quarter (N = 10, 28.6%) had SCT. Emotional overeating and food enjoyment subscale scores showed moderate correlations with the SCT scores, though these associations were not significant when controlling for ADHD symptoms. Daytime sleepiness score in adolescents with SCT was found to be significantly higher than those without. CONCLUSION Sluggish Cognitive Tempo is frequently present in adolescents with obesity and associated with higher levels of emotional overeating, food enjoyment, and daytime sleepiness. Targeting aspects of SCT might offer additional avenues to assist in weight management programs for youth.

Abstract
The past two decades have witnessed substantial interest in sluggish cognitive tempo (SCT), a set of symptoms (e.g., excessive daydreaming, mental confusion, slowed behavior) distinct from attention-deficit/hyperactivity disorder (ADHD) and other psychopathology symptoms. Despite evidence linking SCT to a range of functional outcomes, findings for academic functioning are unclear. The current review summarizes the literature on SCT and academic functioning and offers an agenda for future research. A systematic review was conducted to identify studies assessing SCT and academic outcomes, including academic impairments and performance, in childhood, adolescence, and young adulthood. Sixty studies were retained (53 cross-sectional, 7 longitudinal) from 44 separate samples, with the majority (n = 32, 53%) assessing global ratings of academic impairment and fewer measuring specific academic domains or standardized achievement test scores. Findings were generally consistent in showing SCT to be correlated with global ratings of academic impairment, lower grades, and inconsistently associated with poorer math and reading scores. Findings were more mixed when controlling for ADHD symptoms, intelligence, and/or demographic factors. Overall, SCT is associated with poorer academic functioning, although inconsistencies and key limitations are common across studies. Ten directions for future research are offered to advance understanding of how SCT may be associated with or impact academic functioning.

Abstract
BACKGROUND Sluggish cognitive tempo (SCT) has been proposed to be either its own distinct disorder or a transdiagnostic process. OBJECTIVE To examine SCT within ADHD (and its specific presentations) and internalizing disorders and its relationship with functional impairment, particularly when considered from a multidimensional perspective. METHOD Undergraduate students (N = 2,806) completed self-report scales measuring SCT, ADHD, anxiety, depression, and functional impairment. The SCT scale consisted of three subfactors identified in prior research. RESULTS Students with internalizing disorders were equally as likely as those with ADHD to report clinically significant SCT, and having multiple other disorders predicted especially high levels of SCT symptoms. Only sleepy/sluggish symptoms incrementally predicted impairment. CONCLUSIONS These findings provide more support for SCT as a transdiagnostic process than as a distinct disorder. All areas of SCT symptoms are associated with ADHD, anxiety, and depression, but the sleepy/sluggish symptoms may be uniquely associated with problems in everyday living.

Abstract
OBJECTIVE Cognitive disengagement syndrome (CDS, previously referred to as "sluggish cognitive tempo") is a set of symptoms defined by excessive mind-wandering, mental confusion, and slowed behaviors separable from ADHD inattention. METHOD Of the studies examining CDS in relation to psychosocial outcomes, one of the most established correlates of CDS is social withdrawal. However, studies have yet to test mechanisms or moderators of the link between CDS and social withdrawal. RESULTS As a parallel body of literature exists in developmental psychopathology on predictors and outcomes of social withdrawal, this review merges these literatures to identify themes and advance a conceptual model on mechanisms (e.g., task-unrelated thought, poorer social skills, social anxiety) and moderators (e.g., behavioral inhibition, sex, parenting) of the CDS and social withdrawal link. CONCLUSION This model provides researchers and clinicians with testable hypotheses to better understand the link between CDS and social withdrawal and to identify treatment targets to improve the social engagement of youth with CDS.

Abstract
An international Sluggish Cognitive Tempo (SCT) Work Group proposed a new term for SCT, "cognitive disengagement syndrome," that more accurately describes the syndrome than does SCT. According to the Work Group, symptoms of SCT represent a cognitive dimension (cognitive disengagement) and a motor dimension (hypoactivity). Our study determined (1) if distinct factors representing cognitive disengagement and hypoactivity emerged when SCT items were factor analyzed and (2) the degree of differences in cognitive disengagement and hypoactivity within diagnostic groups. Mothers rated 1,177 children with autism, 725 with ADHD-Combined, and 307 with ADHD-Inattentive (4-17 years) and 665 elementary school children (6-12 years) on the Pediatric Behavior Scale (PBS). SCT prevalence rates were autism 32%, ADHD-Inattentive 27%, ADHD-Combined 18%, and elementary school students 7%. Factor analysis of the SCT items yielded two factors reflecting cognitive disengagement (in a fog/confused and stares/preoccupied/in own world) and hypoactivity (sluggish/slow moving/low energy, drowsy/sleepy/not alert, and tires easily) in all diagnostic groups. Cognitive disengagement prevalence rates and scores were significantly higher than hypoactivity in the autism and ADHD-C groups and in the autism and ADHD-C subgroups of children with SCT (but not in the ADHD-I and elementary school total groups and SCT subgroups). Our findings factor analyzing five SCT items support two SCT subfactors: cognitive disengagement and hypoactivity.

Abstract
OBJECTIVE ADHD is a neurodevelopmental disorder characterized by executive dysfunction and functional impairments including nicotine consumption. Sluggish cognitive tempo (SCT) has been associated with ADHD and posited as an independent construct. The present study hypothesized that SCT would moderate the relationships between ADHD and nicotine-related behaviors. METHOD Participants (n = 309) were recruited using Mechanical Turk and completed measures of ADHD symptoms, SCT, and smoking history. RESULTS ADHD was associated with age of initiation of smoking and more severe withdrawal symptoms for both combustible and electronic cigarettes. SCT significantly moderated the relationship between ADHD and withdrawal symptom severity (both electronic and combustible cigarettes). CONCLUSION The results of the present study suggest that SCT plays an important role in the complex relationship between ADHD and smoking withdrawal. Future research should further explore the construct of SCT to better understand its role in psychopathology and intervention strategies.

Abstract
Sluggish cognitive tempo (SCT) is increasingly conceptualized as a transdiagnostic set of symptoms associated with poorer functional outcomes, although the extent to which SCT is associated with academic functioning remains unclear. This study recruited children based on the presence or absence of clinically elevated SCT symptoms, using a multi-informant and multi-method design to provide a comprehensive examination of academic functioning in children with and without clinically elevated SCT symptoms. Participants were 207 children in Grades 2-5 (ages 7-11 years; 63.3% male), including 103 with clinically elevated teacher-reported SCT symptoms and 104 without elevated SCT, closely matched on grade and sex. A multi-informant, multi-method design that included standardized achievement testing, curriculum-based measurement (CBM), grades, classroom and laboratory observations, and parent and teacher rating scales was used. Children with elevated SCT symptoms had poorer academic functioning than their peers across most domains examined. Specifically, compared to children without SCT, children with elevated SCT had significantly lower grade point average (d = 0.42) and standardized achievement scores (ds = 0.40-0.77), poorer CBM performance including lower productivity (ds = 0.39-0.51), poorer homework performance and organizational skills (ds = 0.58-0.85), and lower teacher-reported academic skills (ds = 0.63-0.74) and academic enablers (ds = 0.66-0.74). The groups did not significantly differ on percentage of time on task during classroom observations or academic enabler interpersonal skills. Most effects were robust to control of family income, medication use, and attention-deficit/hyperactivity disorder inattentive symptoms, although effects for motivation and study skills academic enablers were reduced. This study demonstrates that children with clinically elevated SCT symptoms have wide-ranging academic difficulties compared to their peers without SCT. Findings point to the potential importance of assessing and treating SCT to improve academic outcomes.

Abstract
OBJECTIVE Although peer difficulties and sluggish cognitive tempo (SCT) are related, studies have yet to examine environmental factors that may advance further understanding of this association. The current study tested whether peer difficulties, specifically social competence and peer victimization, interacted with school support, a component of school climate, in relation to adolescents' SCT symptoms. Further, we explored whether these relations would be differentially associated with SCT in adolescents with and without attention-deficit/hyperactivity disorder (ADHD). METHOD Adolescents (N = 288; Mage = 14.08, 45% female, 82.6% White; 52% with ADHD) completed measures of social competence, peer victimization, school climate support, and SCT and ADHD inattentive (IN) symptoms. Parents also reported on adolescents' social competence, SCT, and ADHD-IN symptoms. RESULTS Results indicated that adolescent and parent ratings of lower social competence were both associated with higher adolescent-reported SCT symptoms in the context of low, but not high, school support. Relational and nonphysical victimization were associated with higher self-reported SCT symptoms in the context of low school support. Lower adolescent- and parent-reported social competence were also related to higher parent-reported SCT symptoms, with these associations not moderated by school support. These results remained after controlling for demographics and ADHD-IN symptoms and were similar across adolescents with and without ADHD. CONCLUSIONS Findings from the current study are the first to provide evidence that peer difficulties and school climate are jointly related to adolescents' self-reported SCT and underscore the importance of continued research investigating social adversity and environmental factors in relation to SCT.

Abstract
OBJECTIVE To investigate whether sluggish cognitive tempo (SCT) was associated with anxiety, depression, and academic performance (AP) in children with reading disorder (RD), and whether ADHD-Inattention (ADHD-IN) moderated these relationships. METHOD Parents and teachers of children with RD (N = 147, ages 6-18) completed evaluations of SCT, ADHD, anxiety, depression, and AP, every 3 months for 18 months. Baseline and longitudinal associations between SCT and outcomes, and effect moderation of ADHD-IN, were assessed. RESULTS Teacher-rated SCT was positively associated with teacher-rated anxiety (p < .001) and negatively associated with AP (p < .001) cross-sectionally and longitudinally, with significant effect modification by ADHD-IN for both outcomes. SCT was not associated with depression in adjusted cross-sectional and longitudinal analyses. There were no significant findings for any parent-reported measures. CONCLUSION SCT has negative effects on anxiety and AP in children with RD among individuals with low ADHD-IN according to teacher report. Targeted treatment of SCT may provide substantial benefits.

Abstract
Background Sickle cell disease (SCD) imparts risk for a range of neurodevelopmental and neurocognitive disorders. Sluggish cognitive tempo (SCT) is a distinct syndrome that often co-occurs with attention-deficit/hyperactivity disorder (ADHD) but has not been described in SCD. We investigated the reliability and validity of a SCT measure in SCD and examined associations with biopsychosocial risk factors and functional outcomes. Materials and Methods Caregivers (n = 85) of children with SCD ages 7-16 reported on socio-demographics and the Kiddie-Sluggish Cognitive Tempo (K-SCT) measure, Behavior Rating Inventory of Executive Function, and Conners 3. Disease-related characteristics were extracted from health records. Results The K-SCT demonstrated excellent internal consistency (α = 0.92) and test-retest reliability (r = 0.82, p < 0.001). K-SCT scores were correlated with ADHD-Inattention (r = 0.64, p < 0.001) and ADHD-Hyperactive/Impulsive (r = 0.46, p < 0.001) scores, as well as functional outcomes, including learning problems (r = 0.69, p < 0.001). In multivariate analyses controlling for ADHD symptoms, SCT accounted for unique variance in learning (b = 9.67, p < 0.01) and executive functioning (b = 5.93, p < 0.01). Nearly all participants (93%) with elevated levels of co-occurring SCT and ADHD-Inattention symptoms had significant learning problems. Conclusion The K-SCT is a reliable and valid measure of SCT in SCD. SCT symptoms are associated with learning difficulties even after controlling for ADHD symptoms. Further research is needed to understand the biopsychosocial factors that lead to SCT symptoms in SCD and examine long-term implications of SCT.

Abstract
It is unknown whether sluggish cognitive tempo (SCT) is prospectively associated with depression in adolescence, and possible processes linking SCT to depression remain unexamined. Using a longitudinal study with three timepoints over a two-year period, the current study tested the indirect effects of SCT on depression via peer victimization, specifically physical, relational, and verbal victimization. Participants were 302 adolescents (Mage = 13.17 years; 44.7% female participants; 81.8% White; 52% with ADHD). In the fall of 8th grade, adolescents and parents completed measures of adolescents' SCT and ADHD symptoms. Adolescents completed a measure of peer victimization in spring of 8th grade and a measure of depressive symptoms in 10th grade. Models examining indirect effects were conducted with and without control of baseline ADHD and/or depressive symptoms. Across analyses, adolescent and parent ratings of SCT symptoms uniquely predicted greater depressive symptoms two years later when controlling for adolescent sex, study site, and either 8th grade depressive or ADHD symptoms. Further, adolescents' self-reported 8th grade SCT symptoms predicted 10th grade depressive symptoms via verbal victimization when controlling for 8th grade ADHD symptoms, but not in analyses incorporating 8th grade depressive symptoms. Findings underscore the predictive association of SCT on depressive symptoms, the possible role of adverse peer relationships as a mechanism linking SCT to depression, and the importance of considering ADHD and depressive symptoms in research on longitudinal correlates of SCT.

Abstract
Prior studies have suggested that grit and resilience predict both academic and career success. However, these qualities have not been examined in children with reading disorder (RD). We therefore investigated whether grit and resilience were associated with anxiety, depression, academic performance, and quality of life (QOL) in these students. This 3-year longitudinal cohort study included 163 participants with RD from 3 schools. Evaluations were completed by parents and/or teachers every 3 months. The Grit and Resilience Scale was adapted from the 10-item Connor-Davidson Resilience Scale and the 12-item Grit Scale. Outcome measures included anxiety (School Anxiety Scale - Teacher Report and the 8-item Spence Children's Anxiety Scale), depression (Short Mood and Feelings Questionnaire), academic performance, and QOL (Pediatric QOL Inventory 4.0). Multivariate linear regression models (adjusting for age and sex) assessed the associations at baseline. Repeated measures analysis using mixed-effects models assessed the relationship longitudinally. There were statistically significant associations between grit and resilience and all outcomes at baseline and over time. After adjusting for age and sex, improved grit and resilience was associated with decreased anxiety (β = - 0.4, p < 0.001) and improved academic performance (β = 0.5, p < 0.001) when grit and resilience was measured by teachers, as well as decreased depression (β = - 0.3, p < 0.001) and improved QOL (β = 0.6, p < 0.001) when grit and resilience was measured by parents. Grit and resilience are significantly related to mental health, academic performance, and QOL in children with RD. This suggests that interventions to improve grit and resilience may lead to positive benefits.

Abstract
OBJECTIVE Sleep difficulties, daytime sleepiness, and sluggish cognitive tempo (SCT) are associated with impairments in academic performance. SCT refers to symptoms of sluggishness, tiredness/lethargy, and slowed thinking/processing, but despite symptom overlap with sleepiness, research examining interrelations of SCT with sleep and daytime sleepiness is limited. The aims of this study were to evaluate the relationship between SCT and daytime sleepiness and to examine pathways between sleep, daytime sleepiness, SCT, and academic performance. METHOD Participants were a community sample of 1628 parents/caregivers of children aged between 6 and 10 years who completed questionnaires about their child's behavior, sleep, and academic performance. Confirmatory factor analysis was used to examine whether SCT was distinct from daytime sleepiness. Then, structural equation modeling was used to examine direct and indirect pathways between sleep (sleep-disordered breathing [SDB] symptoms, sleep duration, and latency), daytime sleepiness, SCT, and academic performance in reading, writing, and math. RESULTS SCT and daytime sleepiness were distinct but moderately correlated (r = 0.33, p ≤ 0.001). Sleep, in particular SDB symptoms, predicted increased SCT and daytime sleepiness. SCT was directly and negatively associated with all domains of academic performance, daytime sleepiness was associated with poorer reading performance, and longer sleep duration was directly associated with poorer math performance. SCT and, to a lesser extent, daytime sleepiness mediated effects of sleep on academic performance. CONCLUSION SCT symptoms are important for understanding how sleep difficulties affect academic performance in children. Sleep, daytime sleepiness, and SCT are interrelated but distinct factors that affect children's academic performance.

Abstract
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. METHOD MEDLINE (PubMed), Embase, PsychINFO, and Web of Science databases were searched from September 2009 through December 2019. Articles reporting on reliability (internal consistency, test-retest, and interrater reliability), structural validity (an aspect of construct validity focused on items' convergent and discriminant validity), concurrent and longitudinal external validity, invariance, or intervention/experimental findings were included. RESULTS Full criteria for data extraction and inclusion were met by 76 studies. Nine measures for assessing SCT were identified (7 assessing parent report, teacher report, and/or self-report in children and 2 assessing self-report and/or collateral informant report in adults). Each measure demonstrated acceptable to excellent reliability. All or at least the majority of SCT items on each measure also had structural validity (high loadings on an SCT factor and low loadings on an attention-deficit/hyperactivity disorder [ADHD] inattention factor). Studies have supported the invariance of SCT across sex and time, and there is initial evidence of invariance across informants, youths with ADHD and youths without ADHD, and ADHD presentations. The Child and Adolescent Behavior Inventory (CABI), Child Concentration Inventory, Second Edition (CCI-2), and Barkley Adult ADHD Rating Scale-IV (BAARS-IV) have particularly strong support for assessing parent/teacher-reported, youth self-reported, and adult self-reported SCT, respectively. CONCLUSION The SCT measures included in this review share numerous positive properties, have promising psychometric support, and have proven useful for examining the external correlates of SCT across the life span. Although substantial progress has been made over the last decade, work remains to be done to further improve the assessment of SCT and key directions for future research are provided.

Abstract
Sluggish Cognitive Tempo (SCT) describes a pattern of under-activity, poor initiation, and slowness. It was first reported within the Attention Deficit Hyperactivity Disorder (ADHD) literature and found to be positively associated with the inattentive symptoms of ADHD and negatively or not significantly associated with the hyperactivity/impulsivity symptoms of ADHD. SCT has since been considered applicable to the pediatric oncology population given the emergence of inattentive, sluggish symptoms secondary to cancer treatment. The present study examined the unique contribution of SCT to various processing speed skills in a clinical sample of pediatric brain tumor (BT) survivors in order to determine the degree to which SCT explained timed "cognitive" processing components. Measures included speeded naming, graphomotor speed, and speeded inhibition. Hierarchical linear regression analyses were used to predict performance-based measures of processing speed. After controlling for verbal ability and inattention, SCT, particularly Daydreamy SCT (β = -0.698, p = 0.023), explained 28% of variance in speeded inhibition. SCT did not add significantly to the prediction of speeded naming or graphomotor speed. Findings suggest that the "daydreamy" aspect of SCT, rather than "sluggishness" per se, may be related to more complex, cognitively-demanding tasks with greater executive functioning burdens in BT survivors. Implications for intervention for oncology survivors as well as future research directions are discussed.

Abstract
We examined whether there are factors of SCT in nonclinical young adults and whether SCT factors show differential relationships with depression, anxiety, ADHD, and executive functioning as assessed by self-report (EF-SR) or neuropsychological performance (EF-NP). Factor analysis revealed Daydreaming/Bored (D/B), Lethargy (L), and Cognitive Complaints (CC) factors. CC was associated with anxiety and D/B with depression. CC and D/B were associated with inattentive ADHD, while D/B was associated with hyperactive/impulsive ADHD. While all factors were associated with EF-SR, there were few relationships with EF-NP. Higher CC was associated with lower intellect, and higher D/B was related to better working memory.

Previous studies have demonstrated that sluggish cognitive tempo (SCT) behaviors are empirically distinct from inattentive (IN) behaviors that are used to define attention-deficit/hyperactivity disorder. However, most studies used cross-sectional designs during middle childhood. Using parent and teacher ratings from the Family Life Project (N = 1,173), we investigated the factor structure, longitudinal measurement invariance, developmental trajectories, and predictors of developmental change in SCT and IN from age 3 years through Grade 5. SCT and IN were dissociable but correlated constructs that exhibited longitudinal invariance for both informants. Mean levels of SCT increased modestly with age, becoming more prominent between age 5 years and first grade, while IN was more stable. Lower parental education was associated with higher parent- and teacher-reported SCT, male sex was associated with higher teacher-reported IN, and African American race was associated with higher teacher-reported IN but lower teacher-reported SCT. These findings support the validity of SCT starting in early childhood.

Abstract
Objective: Sluggish cognitive tempo (SCT) symptoms uniquely contribute to psychiatric and functional outcomes in child samples; however, the psychometric properties of SCT measures among adult outpatients are unknown. Method: Adults (n = 124) presenting for an ADHD evaluation provided self- and collateral report of SCT symptoms. Results: The SCT scale had good internal consistency and yielded three factors across raters: Slow/Daydreamy, Sleepy/Sluggish, and Low Initiation/Persistence. SCT scores exhibited convergent validity with ADHD symptoms across raters. Individuals with ADHD received higher SCT ratings than those without ADHD via collateral report, a pattern that was similar when comorbidity was considered. SCT was associated with poorer functioning after accounting for ADHD symptoms with some differential effects based on reporting source. Conclusion: Findings support the internal consistency and validity of a three-factor SCT scale among adult outpatients. Differential results between self- and collateral report demonstrate the importance of multiple reporters of SCT in clinical settings.

Abstract
Sluggish cognitive tempo (SCT) is characterized by excessive daydreaming, slowed thinking, and mental confusion and 'fogginess'. A growing body of research supports the empirical differentiation of sluggish cognitive tempo (SCT) from the inattentive (IN) behaviors that characterize attention-deficit/hyperactivity disorder (ADHD). Further SCT and IN are uniquely associated with clinical correlates across academic, social, and emotional domains; however, there is limited understanding of how neuropsychological functioning contributes to SCT and/or IN behaviors. The two broad domains of neuropsychological functioning that have been most frequently examined in relation to SCT behaviors are processing speed and executive functions (EF). The present study tested whether EF and processing speed measured when children were on average age five years were predictive of teacher-rated IN and SCT behaviors in 1st - 3rd grades. Participants included 1,022 children from the Family Life Project, an ongoing prospective longitudinal study of child development in low-income, non-metropolitan communities. EF and processing speed uniquely made independent contributions to the prediction of IN and SCT. In secondary analyses that focused on specific facets of EF and processing speed, inhibitory control and working memory abilities predicted lower IN but not SCT behaviors, whereas slower processing speed significantly predicted both greater SCT and IN behaviors. These results are discussed as they inform developmental models of SCT and IN.

Abstract
Previous studies have found that sluggish cognitive tempo (SCT) symptoms are often associated with social problems and withdrawn behavior. However, the possible neuropsychological mechanism underlying this relationship remains unclear. Some studies have also found that SCT symptoms are related to deficits in sustained attention and selective attention. However, no study has examined whether attention deficits are related to social problems and withdrawn behavior in children with SCT. This study was the first to examine the neuropsychological correlates of social problems and withdrawn behavior among children with SCT symptoms. The results showed that sustained attention measure (omission) predicted the severity of social problems and withdrawn behavior in children with SCT even after controlling for symptoms of attention-deficit hyperactivity disorder. Selective attention measure (response latency mean) was also found to predict the severity of social problems. These results suggest that the social problems commonly exhibited by children with SCT are related to deficits in sustained attention and attentional control. Thus, our results provide an initial support to the link between attention deficits and social problems among children with SCT.

Abstract
Sluggish cognitive tempo (SCT) is characterized by behavioral symptoms reflecting slowness and lethargy (e.g., sluggishness, appearing sleepy) and inconsistent alertness/mental confusion (e.g., daydreaming, fogginess). SCT is substantially correlated with the inattentive symptoms of attention-deficit/hyperactivity disorder (ADHD) and may be part of that domain, but in cross-sectional data, SCT is also strongly associated with both inattention and depression. To date, no study has examined the prospective associations of SCT symptoms in childhood/adolescence with symptoms of ADHD and internalizing problems in adulthood. Using a sample of 449 twin children and adolescent pairs, prospective multiple regression analyses examined whether self- and parent-reported SCT, depression, and parent-reported symptoms of ADHD predicted symptoms in adulthood 12 years later. SCT and depression at time one were strongly correlated (self-reported SCT and depression r = 0.84; parent-reported SCT and depression r = 0.78). When adult outcomes were separately regressed on each youth symptom dimension, self-reported SCT (β = 0.26, p < 0.0001) and depression (β = 0.13, p < 0.0001) each predicted adult symptoms of depression and self-reported SCT predicted inattention (β = 0.12, p = 0.0026). Parent-reported depression, but not parent-reported SCT, predicted self-reported adult depression symptoms (β = 0.17, p = 0.0003). In contrast, when each adult outcome was regressed simultaneously on youth self-reported SCT and depression, neither predicted adulthood inattention or depression. These findings indicate that SCT in childhood and adolescence is strongly associated concurrently and predictively with both inattention and depression. Theoretical and clinical applications of the construct of SCT must take its robust association with both inattention and depression into account.

Abstract
Objective: The purpose of this study was to reexamine the latent structure of ADHD and sluggish cognitive tempo (SCT) due to issues with construct validity. Two proposed changes to the construct include viewing hyperactivity and sluggishness (hypoactivity) as a single continuum of activity level, and viewing inattention as a separate dimension from activity level. Method: Data were collected from 1,398 adults using Amazon's MTurk. A new scale measuring activity level was developed, and scores of Inattention were regressed onto scores of Activity Level using curvilinear regression. Results: The Activity Level scale showed acceptable levels of internal consistency, normality, and unimodality. Curvilinear regression indicates that a quadratic (curvilinear) model accurately explains a small but significant portion of the variance in levels of inattention. Conclusion: Hyperactivity and hypoactivity may be viewed as a continuum, rather than separate disorders. Inattention may have a U-shaped relationship with activity level. Linear analyses may be insufficient and inaccurate for studying ADHD.

Abstract
Some researchers believe that Sluggish Cognitive Tempo (SCT) should be its own psychiatric disorder. However, despite the abundance of literature describing its possible symptoms, evidence of its clinical impact on cognitive tests and some clinical comorbidities is still weak. This retrospective study aimed to analyze the added clinical value of exploring SCT symptoms prior to a neuropsychological assessment in a youth population diagnosed with an Attention-Deficit/Hyperactivity Disorder (ADHD). For this purpose, we used linear regressions to examine the association between different test results and SCT, as well as logistic regressions to examine the association between the existence of different diagnoses and SCT in a group of 295 ADHD patients [73 females, 24.7%], aged between 6 and 18 years [Mean (SD): 9.91 (3.12)]. Our results showed that parent-reported SCT symptoms did not help predict neuropsychological test outcomes. In addition, they did not predict Specific Learning Disorder (SLD) or Developmental Coordination Disorder (DCD), nor anxiety and depression when we controlled for age, Vanderbilt inattention and hyperactivity subscales, autism spectrum disorder, and intellectual disability. These results requestion the added-value of screening for SCT in similar clinical neuropsychological settings.

Abstract
Few studies have examined whether behavioral sluggish cognitive tempo (SCT) symptoms are related to speeded task performance. Mixed findings in existing research could be due to previous studies using a broad conceptualization of processing speed, not including self-report of SCT symptoms, and relying on non-optimal measures of SCT. Using a multi-informant design with both parent- and adolescent-reported SCT symptoms, the present study provides a preliminary test of the hypothesis that SCT symptoms would be associated with slower performance on tasks having greater graphomotor and fine motor demands. Participants were 80 adolescents (ages 13-17 years; 71% male) with attention-deficit/hyperactivity disorder (ADHD). Adolescents and parents completed ratings of SCT. Adolescents were administered the Wechsler Symbol Search and Coding subtests and the Grooved Pegboard Test. When adjusting for age, sex, and ADHD symptom severity, parent-reported SCT symptoms were not significantly associated with Symbol Search or Coding scores but were significantly associated with slower Grooved Pegboard time. Adolescent-reported SCT symptoms were not significantly associated with Symbol Search but were significantly associated with lower Coding scores and slower Grooved Pegboard time. Findings provide preliminary support for the hypothesis that SCT may be more clearly associated with processing speed task performance as motor demands increase and provide a potential explanation for the mixed literature on SCT in relation to processing speed by demonstrating that the presence and magnitude of associations vary by informant and task.

Abstract
Interest in symptoms of sluggish cognitive tempo (SCT) has led to a number of studies evaluating how these symptoms respond to treatment commonly utilized in youths with symptoms of ADHD. No study to date, however, has examined the extent to which symptoms of SCT predict behavioral treatment response in youths across multiple domains of functioning. The current preliminary investigation integrates a number of methodological (e.g., direct observations) and analytic (e.g., Poisson regression) refinements to evaluate the extent to which symptoms of SCT predict treatment responses across multiple domains including behavioral (e.g., interruptions, rule violations), social (e.g., social skills, negative verbalizations), and severe behavioral difficulties (e.g., intentional aggression) above and beyond other demographic characteristics (e.g., symptom severity, Full Scale Intelligence Quotient [FSIQ]). A relatively small sample of 37 children, aged six to 12 years (M = 8.03, SD = 1.83, 35 males: 2 females) attending an eight week multi-component intensive behavioral treatment program for youths with behavioral difficulties participated in the current study. Baseline parental perceptions of SCT were collected prior to the initiation of treatment. Results from this preliminary investigation revealed that pre-treatment SCT symptoms only predicted a less robust treatment response to time out which was associated also with parent's perceptions of underlying working memory problems. Results revealed also that pre-treatment SCT symptoms failed to predict paraprofessional counselor's and teacher's improvement ratings of both rule following and social skills following treatment. Notably, other potential predictors (e.g., symptom severity, FSIQ) also largely failed to predict behavioral treatment response.

Abstract
Sluggish cognitive tempo (SCT) appears to be distinct from attention-deficit/hyperactivity disorder (ADHD) and unique patterns of association between SCT and comorbid symptoms have been reported in the literature. The current study examined the relation between environmental supports and comorbid concerns among children with high SCT. Parents of children (ages 6-12) with a diagnosis of ADHD and clinically elevated SCT (N = 126) completed measures of emotional/behavioral functioning, child routines, and parental adjustment. Regression analyses revealed that after controlling for child age and parental adjustment, Household and Daily Living routines were associated with lower levels of externalizing symptoms while Discipline routines were associated with higher levels of these symptoms, accounting for nearly 20% of the variance in the equation. The findings suggest that for children with ADHD and high SCT routines may play an important role as an environmental support for externalizing symptoms.

Abstract
To advance the research examining the sluggish cognitive tempo (SCT) construct, a key priority has been to develop assessment tools that are reliable and valid. The current study builds upon existing work by conducting the most thorough psychometric evaluation to date of the teacher-reported Child and Adolescent Behavior Inventory (CABI) SCT and attention-deficit/hyperactivity disorder inattention (ADHD-IN) modules in a large sample of elementary students. Participants were 7,613 students (Grades 2-5; 50.3% boys) attending 24 elementary schools in 3 school districts. Teachers (N = 398) provided ratings of SCT, ADHD-IN, academic impairment, and social impairment. An a priori 2-factor model with cross-loadings found the SCT items to demonstrate excellent structural validity with ADHD-IN items. The measurement properties of the SCT and ADHD-IN constructs were also invariant across sex and grade. SCT and ADHD-IN were both uniquely associated with academic and social impairment. Graded response item response theory analysis indicated that the SCT and ADHD-IN scales provided a high level of information and precision. The current study replicates and extends previous research and provides the strongest psychometric evidence to date of teacher-rated SCT using the CABI. The teacher-report CABI may be especially useful in the school-based screening of SCT and ADHD-IN. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Abstract
Research on the predominantly inattentive attention-deficit/hyperactivity disorder (ADHD-PI) subtype/presentation is important given its high prevalence, but paradoxically it is under-recognized and undertreated. The temporal stability of the inattention symptom could impact the high worldwide prevalence of ADHD-PI. Some evidence suggests differences in the nature of attentional deficit in ADHD-PI vs. that in other subtypes. Impairments in neuropsychological, neurocognitive, and social functioning are also evident in ADHD-PI, which could be specific to the subtype (e.g., processing speed, social perception, and skills), or differ from others in severity. Neuroimaging studies have also revealed ADHD-PI-specific neuropathological abnormalities and those that are shared with other subtypes. ADHD-PI is highly comorbid with learning and internalizing (e.g., anxiety and depression) disorders. There is no solid evidence for ADHD-PI-specific genetic etiologies and differential responses of subtypes to ADHD medications. Translational studies have used the Wistar Kyoto/NCrl substrain which requires further characterizations as an ADHD-PI model. Overall, ADHD-PI research has been conducted in the context of the Diagnostic and Statistical Manual, which arguably does not conform to the widely recognized "dimensional" view of ADHD. The Research Domain Criteria has been proposed to provide a novel framework for understanding the nature of neuropsychiatric illnesses and ultimately improve their diagnosis and treatment.

Abstract
Objective: Although internalizing and externalizing disorders have received considerable attention among young population, the mechanisms that explain the relationships of internalization and externalization symptoms with attention deficit/hyperactivity disorder (ADHD) in children and adolescents are not well understood. Since sluggish cognitive tempo (SCT) symptoms had significant associations with ADHD, and internalization/externalization disorders, we examined whether SCT may mediate between ADHD symptoms and internalizing/externalizing problems during childhood.Methods: We performed a retrospective chart-review of 95 children and adolescents (76 boys and 19 girls, aged 6-16) with ADHD. The severity of ADHD was evaluated by Turgay DSM-IV-Based Disruptive Behavioral Disorders Screening and Rating Scale (T-DSMIV-S) completed by teachers. Measures of SCT, internalisation and externalisation symptoms, social, thought, and attentional problems were based on the Teacher Report Form (TRF) that was completed by subjects' primary teachers.Results: The withdrawn scores were significantly correlated with SCT scores, social problems, and ADHD-inattention. There was an inverse correlation between withdrawn and ADHD-hyperactivity/impulsivity scores. The mediation test using bootstrapping method showed that the indirect coefficient for SCT was significant, after controlling of ADHD-inattention and social problems covariates, consistent with partial mediation.Conclusion: Our results may demonstrate that while externalization symptoms were associated with hyperactivity/impulsivity symptoms of ADHD, the internalization symptoms were significantly related to SCT in youngs with ADHD. Specifically, although social withdrawal was significantly related to ADHD-inattention, this relationship was mediated by the severity of SCT.

Abstract
A growing number of studies support the internal and external validity of youth self-reported sluggish cognitive tempo (SCT) symptoms. However, no study has examined SCT in adolescents without ADHD, examined whether adolescent self-reported SCT is distinct from adolescent self-reported ADHD inattention (ADHD-IN), or evaluated whether links between SCT and internalizing problems differ for adolescents with or without ADHD. The present study is the first to (1) determine the convergent and discriminant validity of self-reported SCT and ADHD-IN symptoms in both adolescents with and without ADHD, (2) test the invariance of SCT and ADHD-IN symptoms across ADHD and comparison groups, (3) examine SCT as uniquely related to a range of internalizing-relevant domains, and (4) evaluate if the association between SCT with internalizing correlates differs for adolescents with or without ADHD. Participants were adolescents (Mage = 13 years) with (n = 162) and without (n = 140) ADHD. Adolescents and parents completed measures of internalizing symptoms and emotion dysregulation; adolescents completed measures of rumination and suicidal ideation. Analyses indicated that 13 of the 15 SCT items demonstrated convergent and discriminant validity from ADHD-IN, and SCT and ADHD-IN demonstrated invariance across the ADHD and comparison groups and across sex. SCT, but not ADHD-IN, was uniquely associated with greater adolescent-reported internalizing symptoms and suicidal ideation. Both SCT and ADHD-IN were uniquely associated with adolescent-reported emotion dysregulation and parent-reported internalizing symptoms. Only ADHD-IN was uniquely associated with parent-reported emotion dysregulation. Findings support the differentiation of adolescent-reported SCT and ADHD-IN and demonstrate associations between SCT and increased internalizing problems in adolescents with and without ADHD.

Abstract
Background/Aims Sensory processing has been theorised to contribute to object and temporal organisation. Sensory processing and organisational abilities in children with inattention-hyperactivity was assessed, and investigated if there was a relationship between the two. Methods A community sample of children aged 9–12 years was categorised into inattentive-hyperactive (n=20) and non-inattentive-hyperactive groups (n=56) using the Vanderbilt Attention Deficit Hyperactivity Disorder Parent and Teacher Rating Scales. The Sensory Profile, Child Organisation Scale and Child Organisation Parent Perception Scale were used to collect additional data. Results Sensory processing and organisational abilities differed significantly between the groups. Object organisation correlated significantly with multisensory processing; temporal organisation failed to correlate with sensory processing. Conclusions Results suggest there is a need to screen children with informant-reported inattention-hyperactivity for sensory processing differences and organisational deficits. Sensory processing and object organisation may be associated; further research on potential factors underlying this association is needed.

Abstract
A recent meta-analysis identified optimal items for assessing sluggish cognitive tempo (SCT) as distinct from attention deficit/hyperactivity disorder inattention (ADHD-IN), and a preliminary study with teacher ratings of children in the United States found strong support for the convergent and discriminant validity of 15 SCT items. The current study evaluated whether the same 15 SCT items demonstrated convergent and discriminant validity from ADHD-IN in a large, community-based sample of children in Spain, and whether validity results were replicated across mother, father, and teacher ratings. Mothers, fathers, and teachers completed measures of SCT, ADHD-IN, ADHD-hyperactivity/impulsivity, oppositional defiant disorder, limited prosocial emotions, anxiety, depression, shyness, peer rejection, social impairment, and academic impairment on 2,142 Spanish children (49.49% girls; ages 8-13). The 15 SCT symptoms demonstrated convergent validity along with discriminant validity with ADHD-IN across all three informants. The SCT symptom ratings also showed measurement invariance across the informants. In addition, SCT and ADHD-IN factors had different and unique associations with the other symptom and impairment factors. The 15 SCT symptoms identified in this study-consistent across mother, father, and teacher ratings-appear appropriate to serve as a standard symptom set for assessing SCT in children. Use of a common set of symptoms in future studies will advance our understanding of the SCT construct, including its etiology and developmental progression, associations with ADHD and other psychopathologies, links to impairment, and implications for clinical intervention.

Abstract
OBJECTIVE Sluggish cognitive tempo refers to a constellation of symptoms that include slowed behavior/thinking, reduced alertness, and getting lost in one's thoughts. Despite the moniker "sluggish cognitive tempo," the evidence is mixed regarding the extent to which it is associated globally with slowed (sluggish) mental (cognitive) information processing speed (tempo). METHOD A well-characterized clinical sample of 132 children ages 8-13 years (M = 10.34, SD = 1.51; 47 girls; 67% White/non-Hispanic) were administered multiple, counterbalanced neurocognitive tests and assessed for sluggish cognitive tempo symptoms via multiple-informant reports. RESULTS Bayesian linear regressions revealed significant evidence against associations between sluggish cognitive tempo and computationally modeled processing speed (BF01 > 3.70), and significant evidence for associations with slower working memory manipulation speed. These findings were consistent across parent and teacher models, with and without control for attention-deficit/hyperactivity disorder inattentive symptoms and IQ. There was also significant evidence linking faster inhibition speed with higher parent-reported sluggish cognitive tempo symptoms. CONCLUSIONS These findings provide strong evidence against characterizing children with sluggish cognitive tempo symptoms as possessing a globally sluggish cognitive tempo. Instead, these symptoms appear to be related, to a significant extent, to executive dysfunction characterized by working memory systems that are too slow and inhibition systems that are too fast. Behaviorally, these findings suggest that requiring extra time to rearrange the active contents of working memory delays responding, whereas an overactive inhibition system likely terminates thoughts too quickly and therefore prevents intended behaviors from starting or completing, thereby giving the appearance that children are absent-minded or failing to act when expected.

Abstract
This exploratory study is the first to investigate whether the construct of sluggish-cognitive tempo (SCT) is related to slowed processing speed in children with traumatic brain injury (TBI), while also considering pre-morbid and injury variables. The study evaluated SCT, as measured by the Child Behavior Checklist (CBCL), and processing speed, as assessed with the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV Processing Speed Index), in children who sustained TBI with a wide range of injury severity. Injury variables examined included the length of coma, presence of neuroimaging findings, and time between injury and assessment. Children's cognitive reserve, as estimated by parental level of education, was a non-injury variable. The participants included 50 children, ages 6-16 years, without co-morbid neurological or psychiatric conditions who underwent a neuropsychological evaluation within 1-12 months after injury. Results indicated no significant correlations between SCT and any of the WISC-IV index scores. Children with a moderate-severe TBI did not differ from those with uncomplicated mild TBI on SCT but they had statistically significant lower WISC-IV Processing Speed. Although parents of children with uncomplicated mild TBI had higher levels of education as compared to parents of children with moderate-severe TBI, there was no statistically significant relationship between the level of parental education and either SCT or Processing Speed. This study suggests that SCT, as measured by the CBCL, is not a sensitive measure of sequelae of pediatric TBI.

Abstract
Objective: This study evaluated which Sluggish Cognitive Tempo (SCT) factors (i.e., Slow, Sleepy, Daydreamer) are most strongly associated with homework motivation, and whether homework motivation mediates the path between SCT and academic impairment. Method: Participants were 285 middle school students (boys 209) in Grades 6 to 8 (ages 10-15 years) who were comprehensively diagnosed with ADHD. Results: Parent- and self-report of SCT Slow behaviors predicted homework motivation above and beyond symptoms of ADHD, oppositional defiant disorder (ODD), anxiety, depression, and intelligence. The mediation models tested were multi-informant and cross-rater (parent-report of SCT to self-report of motivation to teacher-report of homework problems), and suggest that low motivation may help explain the associations between SCT and functional impairment. Conclusion: SCT and motivation are significantly associated constructs. Clinically, youth with ADHD and comorbid SCT may be more likely to present with low motivation, placing them at risk for academic failure. The manuscript discusses potential clinical implications of these findings.

Abstract
Despite increasing interest in sluggish cognitive tempo (SCT) in children, the field is stymied by the lack of a standard symptom set that can be used across studies. Without a standard symptom set, it is difficult to determine if differences across studies are due to methodological or sample differences, or simply the way SCT was measured. To move the field toward a standard symptom set, this study evaluates a teacher-report rating scale of SCT revised based on recent meta-analytic findings that identified optimal items for distinguishing SCT from attention-deficit/hyperactivity disorder inattention (ADHD-IN). Participants were 1,349 students (50.7% male) from grades 2 to 5. Teachers provided ratings of SCT, ADHD-IN, academic impairment, and social impairment. Exploratory structural equation modeling found 15 of the 16 SCT items to demonstrate excellent convergent validity and discriminant validity with ADHD-IN. The measurement properties of the SCT construct were also invariant across sex. SCT was uniquely associated with both academic and social impairment above and beyond ADHD-IN and sex. Although replication and extension is needed, the current study provides the strongest evidence to date of a possible standard symptom set that can be used across studies examining SCT in children.

Abstract
Few studies have examined the longitudinal association between sluggish cognitive tempo (SCT) symptoms and internalizing symptoms, and no study has examined the potentially bidirectional associations between SCT and internalizing symptoms. The present study used a short-term longitudinal design to examine the directionality of the associations between SCT, depressive, and anxious symptoms in children. Teachers of 188 children in 1st to 6th grades (6-13 years of age; 47% boys) provided ratings of children's SCT, anxiety, and depressive symptoms in the fall school semester (T1) and again 6 months later (T2). Children in 3rd to 6th grades (n = 133) provided ratings of anxiety and depressive symptoms at both time points. Cross-lagged panel models examining the longitudinal associations between SCT, anxiety, and depressive symptoms were conducted controlling for sex and grade, with separate models for teacher- and child-reported internalizing symptoms. SCT symptoms at Time 1 (T1) predicted increased depressive symptoms at T2, with findings consistent across teacher-rated depression and child-rated depression. Depression at T1 did not predict SCT at T2. SCT symptoms at T1 also predicted increased teacher-rated anxiety at T2 but not child-rated anxiety. Finally, child-rated anxiety at T1 predicted increased SCT at T2. Findings from this study provide the first evidence that SCT symptoms predict subsequent depressive symptoms and not the reverse. Associations between SCT and anxiety are more nuanced, with results differing based on the informant. Additional studies are needed to replicate and extend these findings across longer developmental periods with more time points and to examine mechanisms of the associations between SCT and internalizing symptoms in children.

Abstract
Sluggish cognitive tempo (SCT) is separable from attention-deficit/hyperactivity disorder (ADHD) and other psychopathologies, and growing evidence demonstrates SCT to be associated with impairment in both children and adults. However, it remains unclear how SCT should optimally be conceptualized. In this article, we argue that multiple models of psychopathology should be leveraged to make substantive advances to our understanding of SCT. Both categorical and dimensional approaches should be used, including the Diagnostic and Statistical Manual of Mental Disorders (DSM) nosology, the Research Domain Criteria (RDoC) initiative, and hierarchical models of psychopathology. Studies are needed to determine whether individuals categorized with SCT can be reliably identified and differentiated from individuals without SCT in pathophysiological, neuropsychological, behavioral, and daily life functioning. Studies are also needed to evaluate the validity and utility of SCT as a transdiagnostic and dimensional construct. In considering SCT as a dimensional and potentially transdiagnostic construct, we describe ways in which SCT might be examined within the RDoC framework, including negative valence systems, cognitive systems, and arousal/regulatory systems, as well as within hierarchical models of psychopathology. Conceptualizing SCT within both categorical and dimensional models of psychopathology will help to better understand the causes, developmental pathways, and clinical implications of SCT, both as a construct in its own right and also in relation to other psychopathologies.
