Investigating the Effect of Sluggish Cognitive Tempo Symptoms Independent of Attention Deficit and Hyperactivity Symptoms on Extremity Injuries in Children and Adolescents

Objective: Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder. ADHD symptoms in childhood cause a number of comorbidities in adulthood, there is scarce information on whether ADHD in childhood increases the risk of sustaining injuries or accidents. Although previous studies have investigated ADHD-related accidents or extremity injuries, no study has yet examined whether the risk of injury increases in the presence of ADHD combined with Sluggish Cognitive Tempo (SCT) or—although still controversial as a diagnosis—in the presence of SCT alone. The aim of present study was intended to fill this gap in knowledge and to elucidate the effect of SCT on the risk of sustaining injuries in individuals with ADHD. Methods: The study included the following groups: Group 1 consisting of patients aged 6–17 years who presented to orthopedics outpatient clinics for extremity injuries and had suspected ADHD, and their parents; Group 2 consisting of children and adolescents aged 6–17 years who had no extremity injury but had ADHD, and their parents, and Group 3 consisting of children and adolescents aged 6–17 years without any extremity injury or psychiatric disorders, and their parents. After the sociodemographic questionnaire was filled, the DSM IV based Screening and Assessment Scale for Attention Deficit and Disruptive Behavior Disorders and Barkley Child Attention Scale (BCAS) were administered by a clinician specialized in pediatric and adolescent mental health. Results: The study included a total of 94 children and adolescents, of whom 37 had both fractures and ADHD (fracture + ADHD), 37 had ADHD alone and no history of fracture (ADHD), and 20 had neither a history of fracture nor psychiatric diagnosis (control). The groups differed significantly in terms of SCT, inattention and hyperactivity scores (p < 0.0001). Based on the results of the regression analysis, it was concluded that the decrease in SCT scores was associated with the fracture + ADHD group; male sex was associated with the ADHD group; and the increase in inattention and hyperactivity scores played a role in the differentiation of the fracture + ADHD group from the control group. Conclusion: The present study was intended to fill this gap in knowledge and to elucidate the effect of SCT on the risk of sustaining injuries in individuals with ADHD. Comparison of the groups in terms of attention deficit, hyperactivity, and SCT scores showed a statistically significant difference among the groups for all three parameters. Regression analysis showed that high SCT scores had a reverse causality with fractures. When evaluated within the context of our study, this seems to act as a mechanism that compensates impulsivity. Although the mechanism is unclear, the strong causality suggests that it may have a protective effect against sustaining injuries.

1 Sluggish Cognitive Tempo in Children and Adolescents with Fetal Alcohol Spectrum Disorders: Associations with Executive Function and Subcortical Volumes

Objective:Fetal alcohol spectrum disorder (FASD) is a common neurodevelopmental condition associated with deficits in cognitive functioning (executive functioning [EF], attention, working memory, etc.), behavioral impairments, and abnormalities in brain structure including cortical and subcortical volumes. Rates of comorbid attention-deficit/hyperactivity disorder (ADHD) are high in children with FASD and contribute to significant functional impairments. Sluggish cognitive tempo (SCT) includes a cluster of symptoms (e.g. underactive/slow-moving, confusion, fogginess, daydreaming) found to be related to but distinct from ADHD, and previous research suggests that it may be common in FASD. We explored SCT by examining the relationship between SCT and both brain volumes (corpus callosum, caudate, and hippocampus) and objective EF measures in children with FASD vs. typically developing controls.Participants and Methods:This is a secondary analysis of a larger longitudinal CIFASD study that consisted of 35 children with prenatal alcohol exposure (PAE) and 30 controls between the ages of 9 to 18 at follow-up. Children completed a set of cognitive assessments (WISC-IV, DKEFS, & NIH Toolbox) and an MRI scan, while parents completed the Child Behavior Checklist (CBCL), which includes a SCT scale. We examined group differences between PAE and controls in relation to SCT symptoms, EF scores, and subcortical volumes. Then, we performed within-and between-group comparisons with and without controlling for total intracranial volume, age, attention problems, and ADHD problems between SCT and subcortical brain volumes. Finally, we performed correlations between SCT and EF measures for both groups.Results:Compared to controls, participants with PAE showed significantly more SCT symptoms on the CBCL (t [57] = 3.66, p = 0.0006), more parent-rated attention problems and ADHD symptoms, lower scores across several EF measures (DKEFS Trail-Making and Verbal Fluency; WISC-IV Digit Span, Symbol Search, and Coding; effect sizes ranging from 0.44 to 1.16), and smaller regional volumes in the caudate, hippocampus, and posterior areas of the corpus callosum. In the PAE group, a smaller hippocampus was associated with more SCT symptoms (controlling for parent-rated attention problems and ADHD problems, age, and intracranial volume). However, in the control group, a larger mid posterior and posterior corpus callosum were significantly associated with more SCT symptoms (controlling for parent-rated attention problems, intracranial volume, and age; r [24] = 0.499, p = 0.009; r [24] = 0.517, p = 0.007). In terms of executive functioning, children in the PAE group with more SCT symptoms performed worse on letter sequencing of the Trail-Making subtest (controlling attention problems & ADHD symptoms). In comparison, those in the control group with more SCT symptoms performed better on letter sequencing and combined number letter sequencing of the Trail-Making subtest (controlling attention problems).Conclusions:Findings suggest that children with FASD experience elevated SCT symptoms compared to typically developing controls, which may be associated with worse performance on EF tasks and smaller subcortical volumes (hippocampus) when taking attention difficulties and ADHD symptoms into account. Additional research into the underlying causes and correlates of SCT in FASD could result in improved tailoring of interventions for this population.

28 Executive Functioning in Children with Sluggish Cognitive Tempo

Objective:Sluggish cognitive tempo (SCT) is an attentional disorder characterized by excessive daydreaming, reduced alertness, slowed motor behavior, and mental fogginess. The purpose of the present study was to examine potential executive functioning group differences between children with high SCT symptoms versus those with low SCT symptoms. It was hypothesized that children with high SCT symptoms would have greater executive functioning deficits than children with low SCT symptoms, as reported by their teachers.Participants and Methods:There were 32 children in this study, between the ages of 6 to 13 (M = 8.94; SD = 1.97). To measure the level of SCT symptomology, an average rating on four items from the Child Behavior Checklist (CBCL; Items 13, 17, 80, 102) and an average rating from five items from the Teacher's Report Form (TRF; Items 13, 17, 60, 80, 102) were acquired and averaged to produce a combined measure of SCT. The present study had fair to good reliability for CBCL and TRF with Cronbach alpha values of .71 and .82 respectively. Eighteen participants had SCT scores above the Garner et al. (2010) cutoff criteria for the CBCL (SCT over 0.67) or the TRF (SCT over 0.75) which placed them in the high SCT group. The 13 participants who did not meet criteria for high SCT were considered the low SCT group. To measure executive function, Behavior Rating Inventory of Executive Function (BRIEF) teacher ratings were used. A general linear model multivariate analysis was conducted on each measure of the BRIEF teacher reports with ADHD-Inattentive (ADHD-IN) and Verbal Comprehension Index (VCI) scores as covariates.Results:There were significant group differences between the BRIEF Teacher Global Executive Composite scores of the high SCT group (M = 60.81, SD = 7.78) versus the low SCT group (M = 50.31, SD = 6.87), F(1, 30) = 11.73, p < .001, np2 = .59. The high SCT group scored significantly higher than the low SCT group on the Initiate (p < .001), Working Memory (p < .001), Plan/Organize (p < .001), Monitor (p < .01), and Organization of Materials (p < .05) subscales. These findings indicate that the children in the high SCT group had greater executive functioning difficulties overall than the low SCT group.Conclusions:Children with high SCT symptoms demonstrated greater executive functioning deficits than children with low SCT symptoms regarding metacognition but not behavioral regulation. This means that children with SCT likely struggle more with initiating tasks, planning, organization, memory, and monitoring their thinking and behaviors than children without SCT. These skills are important for learning, which may at least partially help explain why children with SCT experience problems in school.

64 Sluggish Cognitive Tempo in Pediatric Patients with Post-Acute Sequelae of COVID-19: Moderating Role of Depression on Functional Impairment

Objective:Children with post-acute sequelae of COVID-19 (PASC) often report fatigue, attention problems, anxiety, and low mood. Sluggish cognitive tempo (SCT) is a constellation of behavioral symptoms (e.g., drowsiness, moving slowly, mental fogginess, daydreaming, confusion, or inattention) often associated with but distinct from attention-deficit/hyperactivity disorder (ADHD), executive function deficits and depressive symptoms. Given the apparent overlapping symptoms of PASC and SCT, this retrospective chart review aimed to 1) characterize SCT symptoms among pediatric patients with PASC relative to published normative and clinically referred samples, and 2) examine associations between subscales of SCT with ADHD symptoms, depression, anxiety, and functional impairment in this clinical sample.Participants and Methods:This study included retrospective data from 25 patients with PASC (17 females; Mean age=13.73 years, SD=2.07, range=8-19) who were referred for a neuropsychological evaluation following a multidisciplinary visit at a post-COVID-19 rehabilitation clinic within an academic medical center. Patients’ caregivers completed the SCT Scale, ADHD Rating Scale 5 (ADHD-RS-V),Conners Comprehensive Behavior Rating Scale (CBRS), and Impairment Rating Scale (IRS). Higher scores on the SCT, CBRS, and IRS total reflect more problems in the specified area. Welch’s t-tests were utilized to compare SCT scores from our cohort of pediatric patients with PASC relative to a normative community sample (Penny et al., 2009) and a heterogeneous clinically-referred sample (Koriakin et al., 2015). Bivariate correlations were computed to examine associations between SCT (Daydreamy, Low Initiation, Sluggish/Sleepy), ADHD (Inattention and Hyperactivity subscales from the ADHD-RS-V), affective symptoms (Major Depressive Episode (MDE) and Generalized Anxiety Disorder (GAD) scales from the CBRS), and functional impairment (average score from IRS). Multiple linear regressions were used to determine whether SCT factors independently contribute to variance in functional deficits after accounting for age of evaluation, low mood, and anxiety.Results:Sluggish/Sleepy and Low Initiation were elevated in our cohort with PASC as compared to normative and mixed clinical samples from Penny et al. and Koriakin et al. (t>4.36, p<0.001). Patients with PASC had lower scores on the Daydreamy SCT scale than the clinically referred cohort (t=2.06, p=0.049), but similar to the normative sample (t=1.48, p=0.15). After controlling for age of testing, of the SCT subscales, only Low Initiation was associated with MDE (r=0.62, p=0.005), GAD (r=0.56, p=0.01) and overall Functional Impairment (r=0.48, p=0.04). Low Initiation was not correlated with Inattention or Hyperactivity. Notably, multiple regressions revealed Low Initiation scores were not associated with functional impairment when accounting for depression and anxiety symptoms(Low Initiation: ß=0.48, p=0.04; Low Initiation when depression and anxiety are included in independent regression models: ßs=0.13 and 0.29, ps=0.58 and 0.27 respectively).Conclusions:Children and adolescents with PASC demonstrate more sluggish/sleepy presentation and difficulties with initiating activities or directing effort, as compared to normative and mixed clinically referred samples. Low initiation was associated with symptoms of MDE and GAD and functional impairment, but not with symptoms of ADHD. Depression and anxiety may moderate the association between poor initiation with functional impairment, highlighting the importance of psychological interventions to address mental health among youth with PASC and behavioral/cognitive concerns.

The prevalence of SCT in China, its comorbidity with ADHD and its association with life events and parental-rearing behaviors

Although sluggish cognitive tempo (SCT) symptoms are often observed in children with attention deficit hyperactivity disorder (ADHD), an increasing number of studies have highlighted its uniqueness. Nevertheless, no national survey on SCT among children and adolescents has been conducted in China. Hence, this research aims to study SCT in China and to evaluate the differences between SCT and ADHD symptoms by comparing their risk factors in terms of life events (LE) and parental rearing behaviors (PRB). This cross-sectional study used data from a survey on 71,929 children and adolescents in 5 province-level regions in China to study the incidence and demographic information of SCT in the Chinese population. Subsequently, the study investigated the comorbidity of ADHD and SCT, and conducted three logistic regressions on the LE and PRB scores to predict whether participants develop symptoms of ADHD or SCT, or neither symptom. 6658 participants were allocated into the SCT group, and the weighted point prevalence of SCT was 9.78%. 36.34% of participants with ADHD (n = 676) were found to demonstrate SCT symptoms, whereas no statistically significant difference was observed in its comorbidity to the three ADHD subtypes (χ2 = 1.668, p > 0.05, Δ = 2). The regression results on the presence or absence of ADHD revealed paternal excessive-interference and rejection, and maternal favoring were associated with ADHD diagnosis, whereas paternal punishment and favoring and maternal emotional warmth was related to the absence of ADHD symptoms. Academic stress and maternal excessive-interference were associated with SCT symptoms, and maternal emotional warmth associated with SCT absence. Concerning the presence of ADHD-only or SCT-only symptoms, LE adaptation was found to relate to SCT-only symptoms, while PRB paternal rejection and maternal favoring were associated with ADHD-only symptoms. While evidencing the high prevalence of SCT in China, our findings supported that although ADHD and SCT were highly comorbid, they may be considered two independent disorders with different risk factors. Specifically, participants with SCT symptoms are more vulnerable to stress from LE and tend to face more maladjustment than ADHD and normally-developing participants, and maternal rearing behaviours are the key factors to SCT symptoms. SCT brings global challenges in its diagnosis and treatment, and the challenge is more severe in a mentally stressful environment. Therefore, stress management and SCT etiology studies are recommended.

Sluggish cognitive tempo (Cognitive Disengagement Syndrome) symptoms are more associated with a higher risk of internet addiction and internet gaming disorder than ADHD symptoms: A study with medical students and resident doctors

Background & AimsThe 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. MethodsThe 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. ResultsIn 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 & ImplicationsOur 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.

Effects of prenatal exposure to maternal diabetes mellitus on deep grey matter structures and attention deficit hyperactivity disorder symptoms in children.

The neuronal mechanism linking the association between maternal diabetes mellitus (DM) and risk of attention deficit hyperactivity disorder (ADHD) symptoms and working memory deficits in children was investigated. A total of 6291 children (52% boys) born beyond 28 weeks of gestation were included and underwent brain magnetic resonance imaging scans at 9-10 years. Subcortical brain volumes were estimated from the T1-weighted images. ADHD symptoms were assessed using factorial analysis of the Child Behaviour Checklist completed by parents/caregivers. Working memory performance was assessed with the NIH Toolbox. Compared to unexposed children, those exposed to DM (n=422) had smaller (β=-0.15, p=0.001) volumes of pooled deep grey matter (GM). Regional analysis revealed smaller volumes of the caudate nucleus, putamen, thalamus and cerebellum but not of hippocampus. They also had altered cortico-striatal white matter projection tracts. DM was not associated with working memory deficits or inattention, but with increased hyperactivity/impulsivity and Sluggish Cognitive Tempo symptoms in boys. This hyperactivity/impulsivity symptom in boys was partially mediated by smaller deep GM volume. Exposure to DM during pregnancy leads to altered deep GM development during late childhood in their offspring. This contributed to an increased risk of hyperactivity/impulsivity symptoms in boys.

Sluggish Cognitive Tempo Self Report Scale (SCT-SR): Development and Initial Validation Study

Objective: Sluggish Cognitive Tempo (SCT) is a psychological construct consisting of daydreaming, confusion, slowness in movements, lethargy, and low motivation. It is important to develop a self-report scale to evaluate SCT symptoms in children and adolescents in order to meet the following needs; (1) Considering the closeness of SCT symptoms with internalized symptoms, it can provide more reliable information, (2) It allows information to be obtained from multiple informants, and (3) The main symptoms of SCT include subjective experiences such as daydreaming and mind wandering that may be difficult to observe from the outside. Therefore, it was aimed to develop a self-report SCT scale. Method: A total of 467 adolescents and 178 parents participated in the study. Data were collected with scales. Results: The scale consists of 20 items and a single factor. Factor loadings were between 0.60 and 0.81. Conclusion: Sluggish Cognitive Tempo Self-Report Scale is a valid and reliable self-report scale.

Prevalence of Attention Deficit Hyperactivity Disorder and Sluggish Cognitive Tempo Symptoms in Children Presenting with Foreign Body Ingestion: A Case-Control Study

Foreign body ingestion (FBI) is one of the common causes of emergency admissions in infancy and childhood. Although the large majority of children who present with the FBI have no psychiatric diagnosis, present studies demonstrate that attention deficit hyperactivity disorder (ADHD) and related psychiatric problems might be a risk factor for FBI. This study aimed to compare the demographic variables and attention deficit hyperactivity disorder levels and sluggish cognitive tempo symptoms (ADHD-SCT) in children who ingested foreign bodies with healthy children. Also, we aimed to address the relationship between ADHD-SCT symptoms and the age of FBI. The FBI group comprised 44 children (age 2-8, median age: 5, 68.2% boys) admitted to the emergency, pediatric surgery, and pediatric gastroenterology department after FBI, and the healthy control group comprised 30 children (age 3-8, median age: 6, 56.7% boys). We administered the sociodemographic information form, SNAP-IV ADHD rating scale, and Barkley’s child SCT ratings scale to both groups of parents. Our results demonstrated that maternal education level was significantly lower in the FBI group, although other demographic characteristics of the samples were similar (p=0.023). In addition, ADHD-hyperactivity/impulsivity scores were significantly higher in the FBI group (p=0.01). Still, there were no significant differences in ADHD-inattention, SCT-daydreaming, and SCT-sluggishness scores (for all, p&gt;0.05). We found positive-moderate relationships between SCT-daydreaming and sluggishness symptoms and FBI age (r=0.314, r=0.348, respectively). This means that higher SCT scores are related to an older FBI age. In conclusion, for the first time, we evaluated the ADHD and SCT symptoms in young children against FBI and found that ADHD-hyperactivity, but not ADHD-inattention symptoms, were significantly higher in the FBI group, and SCT symptoms increase the risk of FBI at an older age. In addition, we found that a lower maternal education level could be an additional risk factor for FBI. Despite the high hyperactivity in the FBI group, the low rate of child psychiatry evaluation should be considered when evaluating a child.

The association between autistic-like traits and sluggish cognitive tempo symptoms in children with ADHD

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. The parents completed Barkley’s Child Attention Survey and Autism Spectrum Screening Questionnaire. A mental status examination and a semistructured interview were applied to detect comorbidities. Results: Approximately 54,2% (n = 26) of the participants with high ALT levels had higher SCT. SCT symptoms were positively associated with ALT levels. Moreover, the association between SCT and ALTs remained significant after controlling for age, gender, parental ages at giving birth and inattentive presentation of ADHD. SCT predicted higher levels of ALTs, and ALTs predicted higher levels of SCT. Conclusion: The present study provided evidence of an association between SCT and ALTs in ADHD children even when controlled for inattentive presentation and other child- and parent-related variables. The findings may contribute to clarifying some pieces of the clinical picture by revealing the interrelationship between SCT and ALT accompanying ADHD in understanding the underlying transdiagnostic structures of clinically heterogeneous ADHD.

Sluggish cognitive tempo symptoms cooccurring with attention deficit hyperactivity disorder

BackgroundIn the current study, the main aim was investigating the sociodemographic features and sluggish cognitive tempo symptoms of children diagnosed with attention deficit hyperactivity disorder and followed at an attention deficit hyperactivity disorder-specific outpatient clinic.ResultsThe data of 200 boys and 200 girls who were followed up at the attention deficit hyperactivity disorder outpatient clinic were retrospectively compared. The scores of Turgay’s Scale-Disruptive Behavior Disorders Screening and Rating Scale, the Sluggish Cognitive Tempo subscale of the Children Behavior Checklist, and Conners Rating Scales Revised-Parent and Teacher Forms were analyzed. Among the group with Sluggish Cognitive Tempo scores, the ratio of girls was higher and the mean age at which symptoms of attention deficit hyperactivity disorder were recognized and treatment was offered was significantly older than that of the children with <4 scores. Both internalizing and externalizing symptoms were more frequent among the attention deficit hyperactivity disorder children who had Sluggish Cognitive Tempo scores ≥4.ConclusionsThere is increasing evidence distinguishing sluggish cognitive tempo from attention deficit hyperactivity disorder, and in this study, we would like to highlight the appearance and clinical manifestation of these disorders together. Further research, including Sluggish Cognitive Tempo children from the general population, is warranted to understand the characteristics that accompany and differentiate attention deficit hyperactivity disorder.

Sluggish Cognitive Tempo (SCT), Comorbid Psychopathology, and Functional Impairment in College Students: The Clinical Utility of SCT Subfactors

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.

Cognitive and behavioral predictors of procrastination behavior in adolescents at a mental health clinic in Turkey.

Procrastination behavior (PB) negatively impacts individuals' daily lives. Based on existing evidence that states executive function (EF) problems and internalizing symptoms (IS) are related to PB, this study examined IS, EF problems, and sluggish cognitive tempo (SCT) symptoms in adolescents, and their relationships with PB and gender. The sample consisted of 78 adolescents (56.4% female) aged 12-18years. Participants and their families completed the Children's Depression Inventory (CDI), Screen for Child Anxiety Related Disorders (SCARED), Barkley Sluggish Cognitive Tempo Scale-Children and Adolescent (BSCTS-CA), General and Academic Procrastination Scales, Behavior Rating Inventory of Executive Function (BRIEF), and Strengths and Difficulties Questionnaire (SDQ). The scores for academic PB were significantly positively associated with the CDI, SCARED, subscales comprising the metacognitive index of the BRIEF, and all four subscales of the SDQ but not with SCT. General and academic PB yielded similar results except for the conduct problems. Academic PB and EF problems were more prevalent in males. Lack of organizational skills, a part of EF; IS; and attention problems were associated with academic and general PB in girls and boys. Adolescents who have difficulty organizing their work and attention problems may have higher PB.

Sluggish Cognitive Tempo among Iranian Children and Adolescents: A Validation Study of the Farsi Child and Adolescent Behavior Inventory (CABI)-Parent Version.

Sluggish cognitive tempo (SCT), recently renamed cognitive disengagement syndrome (CDS), is a set of behavioral symptoms that includes excessive daydreaming, mental confusion and fogginess, being lost in one's thoughts, and slowed behavior and thinking. Symptoms of SCT show overlap with a broad range of other symptoms such as attention-deficit/hyperactivity disorder inattention, anxiety, and depression, or oppositional defiant disorder (ODD). To measure SCT, one of the optimal measures is the Child and Adolescent Behavior Inventory (CABI). Here, we report the psychometric properties of the Farsi version of the CABI Parent Version, including the CABI SCT scale and its subscales. The participants were the parents of 209 children and adolescents (53.9% girls; ages 8-19 years; Mage = 14.23, SDage = 2.72). Parents completed the SCT, ADHD inattention (ADHD-IN), ADHD-hyperactivity/impulsivity (ADHD-HI), oppositional defiant disorder (ODD), limited prosocial emotions (callous-unemotional (CU) traits), anxiety, depression, social impairment, and academic impairment scales of the Child and Adolescent Behavior Inventory (CABI). Parents also completed four dimensions of the Strengths and Difficulties Questionnaire (SDQ: emotional problems; conduct problems; peer problems; prosocial behavior), and five dimensions of the Kidscreen questionnaire (physical health; psychological well-being; autonomy and parental well-being; peers and social support; school environment). SCT symptoms demonstrated strong discriminant validity from the ADHD-IN symptoms. SCT showed stronger first-order and unique associations than ADHD-IN with anxiety, depression, and ODD, whereas ADHD-IN showed stronger first-order and unique associations than SCT with ADHD-HI, CU, and social and academic impairment. Further, SCT showed stronger first-order and unique associations than ADHD-IN with more emotional problems, peer problems, and with lower prosocial behavior, as assessed with the SDQ. Higher scores for SCT were associated with lower psychological well-being, autonomy and parental relations, and lower peer and social support, as assessed with the Kidscreen. Higher ADHD-IN scores were associated with lower peer and social support, and a lower school environment. The Farsi version of the CABI-Parent Version has very good psychometric properties for assessing SCT and other dimensions of psychopathology/impairment and replicates the findings from similar studies with children and adolescents from South Korea, Spain, Turkey, and the United States. Accordingly, the present study provides further support of the transcultural validity of the sluggish cognitive tempo construct.

Academic functioning in children with and without sluggish cognitive tempo

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.

Comparison of the Cognitive Disengagement and Hypoactivity Components of Sluggish Cognitive Tempo in Autism, ADHD, and Population-Based Samples of Children.

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 (4-17years) and 665 elementary school children (6-12years) 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.

Abnormal physiological responses toward sensory stimulus are related to the attention deficits in children with sluggish cognitive tempo.

Previous studies have found that sluggish cognitive tempo (SCT) is often associated with difficulties in real-life functioning, such as social problems, emotional difficulties, and academic learning difficulties. However, the underlying mechanisms contributing to the SCT symptoms and its associated real-life difficulties have still not been clearly understood. A previous study has found that SCT symptoms were associated with hypoarousal and hyperarousal toward the sensory stimulus. However, it is still unclear whether such abnormal arousal regulation is related to sustained attention difficulties that have been found to be related to social difficulties and withdrawn behavior in children with SCT. In this study, arousal regulation deficit in SCT is examined by the physiological responses quantified by HRV and EEG in the sensory challenge paradigm. This study aimed to establish a linkage between arousal regulation reflected by HRV and EEG and attention difficulties in children with SCT. The results of this study showed that higher theta power in the auditory stimulation condition than in the resting condition was associated with higher omission errors in sustained attention tasks in the SCT group. It was also found that higher parasympathetic activities during sensory stimulation conditions were associated with higher commission errors in the SCT group. These results reflected that hypersensitivity toward stressful sensitivity toward a stressful sensory stimulus is associated with attention difficulties in children with SCT. This further supported the notion that SCT should be conceptualized as a condition characterized by multiple deficits in different biological systems, such as the cognitive system, the negative valence system, and the arousal regulatory system.

Sluggish Cognitive Tempo in Pediatric Sickle Cell Disease.

BackgroundSickle 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 MethodsCaregivers (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.ResultsThe 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.ConclusionThe 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.

Psycholinguistic profiling of children with sluggish cognitive tempo

ABSTRACT Language disorders are frequently comorbid with attention deficit/hyperactivity disorder (ADHD). Sluggish cognitive tempo (SCT), a second attention disorder, may potentially explain some of the links between language disorders and ADHD. In this study we examined the psycholinguistic abilities of 207 children (mean age 7;10) with and without clinically significant levels of SCT symptoms to determine the degree to which symptoms of language disorder co-occur in cases of SCT. Analyses of children’s tense-marking, nonword repetition, and sentence recall indicated that deficits in these areas were not associated with SCT. Instead, SCT appears to be more closely aligned with features of social (pragmatic) communication disorder.

Sluggish cognitive tempo profiles in survivors of childhood cancer as compared to children with attention-deficit/hyperactivity disorder.

Neurocognitive late effects including problems with attention have been reported in pediatric oncology survivors. While some researchers have characterized these late effects as similar to symptoms of attention-deficit/hyperactivity disorder, inattentive presentation (ADHD-I), there remains some controversy as to whether these concerns in oncology patients are best conceptualized according to an ADHD-I or sluggish cognitive tempo (SCT) framework. The aim of this study was to describe SCT symptoms in children with ADHD-I or oncology diagnoses; identify groups of SCT symptoms among children with brain tumors (BT), acute lymphoblastic leukemia (ALL), or ADHD-I; and identify whether specific SCT profiles are associated with these diagnoses. The sample was comprised of 364 youth (146 BT, 149 ADHD-I, 69 ALL) referred for a neuropsychological evaluation at an academic medical center. Caregivers completed the SCT scale as part of the clinical evaluation. Groups differed on mean scores for the SCT scales (Total, Sleepy/sluggish, Low initiation, and Daydreamy) by diagnosis (all p < 0.05), with the ADHD-I group having higher SCT symptoms on all scales. Latent profile analysis showed significant differences between latent SCT classes according to ADHD-I versus cancer diagnosis. The ADHD-I group was significantly more likely to be in the high SCT class compared to the oncology groups. Findings add to the understanding of SCT symptoms in pediatric oncology survivors. There is utility in applying the SCT framework to the oncology population; however, pediatric survivors are likely to be rated differently than youth with ADHD-I. Implications and future directions are discussed.
