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 & 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 (ß = -0.37, p = 0.001) on increased risk of IA, Inattention (ß = 0.19, p = 0.028), Daydreaming (ß = 0.62, p0.001), and Sluggishness ( ß = 1.12, p0.001) had significant positive effects. On the other hand, results revealed that male gender (ß = 5.08, p0.001), IA scores (ß = 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.

Agreement between mother, father, and teacher ratings of cognitive disengagement syndrome (sluggish cognitive tempo) in children with autism and children with ADHD.

No studies have analyzed differences between mother, father, and teacher ratings of cognitive disengagement syndrome (CDS; formerly sluggish cognitive tempo). The sample included 1,115 children with autism and/or attention-deficit/hyperactivity disorder (ADHD) 4-16 years of age who were rated by mothers on the Pediatric Behavior Scale. Subsets of these children were also rated by fathers and/or teachers, resulting in 896 mother/father, 964 mother/teacher, and 745 father/teacher dyads. The CDS factor comprised four items assessing the core features of CDS: cognitive disengagement (in a fog/confused and stares/preoccupied/in own world) and hypoactivity (sluggish/slow moving/low energy and drowsy/sleepy/not alert). Overall, 37% of teachers, 22% of mothers, and 16% of fathers rated the children as significantly elevated on CDS symptoms. Teacher scores were significantly higher than mother scores, whose scores exceeded those of fathers. Agreement on whether a child had CDS was fair-moderate for mothers and fathers but poor for parents and teachers. Findings of more severe CDS teacher than parent ratings are in marked contrast to the opposite pattern found in studies of anxiety, depression, ADHD, oppositional behavior, conduct problems, autism, bullying, and victimization. Children may display fewer behavior problems at school than at home, and parents may be more aware of their child's internal state than teachers. However, teachers may be more aware of the cognitive component of CDS that might interfere with functioning in the classroom more so than at home. Cognitive demands in school may reveal and intensify CDS symptoms. Findings highlight the importance of multi-informant ratings in research and clinical practice.

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.

Psychometric Properties of the Turkish version of the Child and Adolescent Behavior Inventory Sluggish Cognitive Tempo Scale (CABI-SCT) in Children and Adolescents.

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.

Executive Functions Contribute to the Differences Between ADHD and Sluggish Cognitive Tempo (SCT) in Adults.

OBJECTIVES: This paper analyses the relationship between sociodemographic variables, executive dysfunctions, Sluggish Cognitive Tempo (SCT) and the mainly dimensions of ADHD: hyperactivity-impulsivity (ADHD-H/I) and inattention (ADHD-IN) in Brazilian adults. METHOD: A cross-sectional, exploratory, and comparative design was used. A total of 446 participants (295 women) aging from 18 to 63 years old (M = 3,499 years, SD = 10.7) were recruited on the internet. Correlations, t independent tests and regressions were conducted. RESULTS: Higher scores in ADHD dimensions were associated to more executive functioning problems and time perception distortions in comparison to those participants without significant ADHD symptoms. However, ADHD-IN dimension as well as SCT were higher associated with these dysfunctions than ADHD-H/I. The regression results showed that ADHD-IN was more related to Self-Management to time while ADHD-H/I to Self-Restraint and SCT to Self-Organization/Problem Solving. CONCLUSION: This paper contributed to the distinction between SCT and ADHD in adults in important psychological dimensions.

An Examination of the Role of Sluggish Cognitive Tempo as a Moderator of the Relationship Between ADHD and Nicotine Use.

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.

Psycholinguistic profiling of children with sluggish cognitive tempo.

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: Association with neuropsychological test scores, motor incoordination, and dysgraphia in elementary school children.

Research on the relationship between sluggish cognitive tempo (SCT) and scores on neuropsychological tests (such as those measuring processing speed and reaction time) is inconclusive, and the association between SCT and motor incoordination and dysgraphia has not been objectively investigated. Mothers of 413 elementary school children (6-12 years of age) rated their children on the Pediatric Behavior Scale (PBS), which yields psychological problem scores, including SCT. Children were administered an extensive battery of neuropsychological tests assessing processing and performance speed, working memory, immediate and delayed recall, sustained attention, response inhibition, cognitive flexibility, fine motor manipulative skill, verbal fluency and retrieval, set shifting, and interference control, as well as intelligence and reading and math achievement. Only three of the 19 correlations between SCT and neuropsychological scores were significant, and all involved graphomotor tests (two timed and one untimed). In regression analysis, the strongest independent predictor of SCT was the maternal PBS incoordination factor score, followed by ratings of autism, inattention, and depression. Neuropsychological test scores did not contribute significantly more to predicting SCT. Among the incoordination PBS factor items, clumsy and draws or writes poorly were significant SCT predictors. Our novel and unexpected findings showed that motor incoordination was a stronger correlate of SCT than other variables assessed in our study, including those previously linked with SCT. Future SCT research needs to include measures of incoordination and dysgraphia in order to replicate and expand upon the current findings. Our results suggest that SCT traits are not reliably measured by currently available neuropsychological tests.

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.

Sluggish Cognitive Tempo (Cognitive Disengagement Syndrome) and Academic Functioning: A Systematic Review and Agenda for Future Research.

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.

The comparison of sluggish cognitive tempo, processing speed, and executive functions in female children with specific learning disabilities and typically developing female children: A pilot study.

This study investigated the association of sluggish cognitive tempo (SCT), processing speed, and executive function (EF) in children with specific learning disabilities (SLD), and the typically developing children (TD) (60 female students aged between 8 and 10). Child and Adolescent Behavior Inventory-Parent Version (CABI), the Barkley Deficits in Executive Functioning Scale-Children and Adolescents (BDEFS-CA), and Wechsler Intelligence Scale for Children-IV (the Processing Speed Index (PSI) were used to assess SCT, processing speed, and EF. The results showed that SCT problems were higher in children with SLD (p < 0.001). In addition, results showed that children with SLD had poorer performance on processing speed (p < 0.001) compared to the TD group. Executive dysfunctioning in self-management to time, self-organization, problem-solving, self-restraint, self-motivation, and self-regulation of emotions were poorer in children with SLD than TD group (p < 0.05). This study provides initial evidence that SCT symptoms are poor in female children with SLD, and associated with executive dysfunction and poor processing speed.

Iron Deficiency in Infancy and Sluggish Cognitive Tempo and ADHD Symptoms in Childhood and Adolescence.

OBJECTIVE: To determine whether iron deficiency in infancy is associated with sluggish cognitive tempo (SCT) or attention-deficit/hyperactive-impulsive (AD-HI) symptoms in childhood and adolescence, and whether such behaviors contribute concurrently and predictively to lower verbal and mathematical abilities. METHOD: Chilean children (N = 959; 50% male, of Spanish or indigenous descent from working-class backgrounds) were rated by mothers for SCT or AD-HI symptoms at ages 5, 10, and 16 years. Children completed standardized tests assessing verbal and mathematical abilities at ages 5, 10, and 16. At ages 12 and 18 months, children were assessed for iron deficiency. RESULTS: Adjusting for a comprehensive panel of covariates, greater severity of iron deficiency in infancy was associated with more frequent SCT and AD-HI symptoms at all ages studied. Most effects of iron deficiency on children's verbal and math skills were indirect, mediated through AD-HI behaviors. Children's AD-HI symptoms related to lower verbal and math test scores within age and across age. CONCLUSIONS: The long-term associations found between infant iron deficiency and SCT and AD-HI behaviors suggest that the neurodevelopmental alterations that stem from postnatal iron deficiency might play an etiological role in the development of ADHD. Screening for early-life nutritional deficiencies among children with SCT or ADHD symptoms might prove useful, and behavioral screening of children with a history of iron deficiency seems warranted. Interventions that support brain development after early nutritional deprivation also would be beneficial.

Sluggish cognitive tempo, eating habits, and daytime sleepiness in obese adolescents.

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.

Report of a Work Group on Sluggish Cognitive Tempo: Key Research Directions and a Consensus Change in Terminology to Cognitive Disengagement Syndrome.

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.

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 (4-17 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.

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.

Sleep patterns, sluggish cognitive tempo, and daytime sleepiness - a commentary on Fredrick et al. (2022).

Fredrick et al. (Journal of Child Psychology and Psychiatry, 2022) showed in their cross-sectional and observational study that higher Sluggish Cognitive Tempo (SCT) traits were associated with more impaired subjective and objective sleep parameters. Importantly, data were gathered from adolescents and their parents, thus, enhancing the validity of the findings. In addition, the observed pattern of associations was unrelated to ADHD traits, age, sex, medication, or pubertal development. In the present commentary, we acknowledge the scientific value and practical and clinical implications of these findings. For future studies, we propose seven research avenues, which might help to further clarify the neurophysiological, psychological, and behavioral associations between SCT traits and sleep patterns.

The External Validity of Sluggish Cognitive Tempo Versus Inattention in Behavioral, Social Interaction, and Academic Performance Measures.

BACKGROUND: The main objective was to replicate data on the external validity of the Sluggish Cognitive Tempo (SCT) dimension, versus ADHD Inattention (IN), with the Spanish version of the Child and Adolescent Behavior Inventory (CABI) SCT subscale [ Cuestionario sobre el Comportamiento de Niños ] (Burns et al., 2015). METHOD: 273 mothers and 255 fathers evaluated their 9 to13 year old children on SCT, IN and other CABI internalizing externalizing, academic impairment and social interaction measures. RESULTS: As hypothesized, the relationship between SCT and externalizing measures, in contrast to IN, was practically nonexistent, whereas both measures were related to internalizing and social interaction measures. Thus, the unique predictive capacity of SCT and IN was significant and similar on internalizing measures, except in the case of shyness, where SCT was better, while IN was better on externalizing measures. CONCLUSIONS: The data largely replicated previous results: SCT, despite its relationship with IN, is capable of predicting a significant proportion of anxiety, depression, and excessive shyness problems and, unlike IN, functions as a protective measure for externalizing problems.

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

PURPOSE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.
