We investigated the etiological relationships between the three ADHD dimensions of Inattentive Problems (INP), Hyperactivity-Impulsivity Problems (HIP) and Sluggish Cognitive Tempo (SCT) as measured by the CBCL 6–18 questionnaire. Multivariate models were applied to 398 twin pairs (374 boys and 422 girls) aged 8 to 17 years (M = 13.06, SD = 2.59) belonging to the population-based Italian Twin Registry. The INP, HIP and SCT problem scores were moderately-to-substantially (range 0.29–0.47…

Sluggish cognitive tempo and peer functioning in school-aged children: A six-month longitudinal study
Sluggish Cognitive Tempo and Depressive Symptoms in Children and Adolescents Predict Adulthood Psychopathology.
TLDR
It is indicated that SCT in childhood and adolescence is strongly associated concurrently and predictively with both inattention and depression.
Sluggish Cognitive Tempo: Sociodemographic, Behavioral, and Clinical Characteristics in a Population of Catalan School Children
TLDR
While girls are less prone to SCT symptoms, some socioeconomic indicators, dyslexia, and inattention symptoms as well as exposure to smoking at home increase the risk of SCT and must be taken into account during assessments.
Testing the Longitudinal Structure and Change in Sluggish Cognitive Tempo and Inattentive Behaviors From Early Through Middle Childhood
TLDR
Findings support the validity of SCT starting in early childhood, as dissociable but correlated constructs that exhibited longitudinal invariance for both informants were found.
Sluggish Cognitive Tempo and Personality: Links to BIS/BAS Sensitivity and the Five Factor Model.
Sluggish Cognitive Tempo and ADHD Symptoms in a Nationally Representative Sample of U.S. Children: Differentiation Using Categorical and Dimensional Approaches

TLDR
This is only the second study to examine the distinction of clinically-elevated SCT from ADHD in a national sample of children and extends previous findings to a broader array of functional outcomes.
Sluggish Cognitive Tempo (Concentration Deficit Disorder?): Current Status, Future Directions, and a Plea to Change the Name

TLDR
Evidence to date is nearing a critical mass that likely supports the conclusion that SCT is a distinct disorder of attention from ADHD, yet one that may overlap with it in about half of all cases.
Attention-deficit/hyperactivity disorder and sluggish cognitive tempo throughout childhood: temporal invariance and stability from preschool through ninth grade.
TLDR
Results indicated that both ADHD and SCT are highly stable across these years of development, that these symptom dimensions are related but also separable, and that hyperactivity/impulsivity and S CT are both more strongly correlated with inattention than with each other and show differential developmental trajectories.
Sluggish Cognitive Tempo: realidades y controversias
Lately it has grown a considerably interest in a dimension known as Sluggish Cognitive Tempo (SCT), which refers to individuals who have a different inattentive pattern as the one described for…
Sluggish cognitive tempo and its neurocognitive, social and emotive correlates: a systematic review of the current literature
TLDR
From the current literature, it can be concluded that SCT is a psychometrically valid construct with additive value in the clinical field of ADHD, oppositional defiant disorder (ODD), internalizing disorders and neuro-rehabilitation.

Validity of the Sluggish Cognitive Tempo, Inattention, and Hyperactivity Symptom Dimensions: Neuropsychological and Psychosocial Correlates
TLDR
The distinct factors of hyperactivity-impulsivity and SCT had unique associations with impairing comorbidities and are roughly equivalent in predicting external correlates of ADHD-related impairment.
A Longitudinal Twin Study on the Association Between Inattentive and Hyperactive-Impulsive ADHD Symptoms
TLDR
Quantitative genetic cross-lagged analyses showed that the association of the ADHD dimensions over time is influenced by stable as well as newly developing genetic factors, with hyperactivity-impulsivity in middle childhood predicting the presence of inattentiveness in early adolescence, but not vice versa.
A general population twin study of the CBCL/6-18 DSM-oriented scales.
TLDR
Several common risk factors of both genetic and environmental nature can simultaneously affect a child's proneness to develop the psychopathological signs and symptoms captured by the CBCL/6-18 DOS.
The Relation Between Sluggish Cognitive Tempo and DSM-IV ADHD
TLDR
Results suggest that SCT is an internally consistent construct that is significantly associated with DSM-IV inattention.
Dimensions and Correlates of Attention Deficit/Hyperactivity Disorder and Sluggish Cognitive Tempo
TLDR
Sluggish Cognitive Tempo symptoms were greatest in youth with ADHD Inattentive type, but were also found in non-ADHD clinical groups, and its clinical utility is still unclear.
Genetic and environmental influences on ADHD symptom dimensions of inattention and hyperactivity: a meta-analysis.
TLDR
Results indicated that both dimensions were highly heritable (genetic factors accounted for 71% and 73% of the variance in INATT and HYP, respectively), however, the 2 dimensions were distinct as to the type of genetic influence.
Sluggish Cognitive Tempo in Psychiatrically Hospitalized Children: Factor Structure and Relations to Internalizing Symptoms, Social Problems, and Observed Behavioral Dysregulation
TLDR
Results of the CFA analyses demonstrated that SCT is distinct from these other dimensions of child psychopathology, including ADHD inattention, depression, and anxiety.
Hyperactive-Impulsive Symptom Scores and Oppositional Behaviours Reflect Alternate Manifestations of a Single Liability
TLDR
In middle childhood, symptoms of hyperactivity-impulsivity and oppositional behaviour may represent the same underlying liability, whereas the inattentive domain is more distinct, and rater bias may contribute to the overlap.

TLDR
Findings from the present study support the notion that DSM-IV-defined inattention constitutes a somewhat heterogeneous condition and can further the theoretical understanding of the neuropsychological impairments and comorbid behavioral problems associated with ADHD symptoms.
The Nature of Covariation Between Autistic Traits and Clumsiness: A Twin Study in a General Population Sample
TLDR
Bivariate twin analyses showed that a genetic etiological overlap, rather than direct causation, is a plausible explanation for the association between clumsiness and autistic-like traits, as measured by indices derived from the parent-rated CBCL scale.
