Sluggish Cognitive Tempo Symptoms, But Not ADHD or Internalizing Symptoms, Are Uniquely Related to Self-Reported Mind-Wandering in Adolescents With ADHD

Psychopathology of cognitive disengagement syndrome (CDS): a network analysis based on CBCL scales in 72,106 Chinese school students

Cognitive Disengagement Syndrome (CDS) is a cluster of behavioral problems that severely affect an individual's functioning. Currently, there is no consensus on the main clinical features of CDS, and further exploration in large samples is needed. Using a cluster-stratified random sampling method, 72,106 children and adolescents were recruited from five provinces in mainland China for this study. Using both the traditional two-factor scoring method and the CBCL DSM-oriented scales, we assessed individual behavioral problems from psychopathological and DSM-oriented perspectives. Network analysis was employed to explore the relationship between CDS and behavioral problems. The various networks were compared by gender and age subgroups. Among 72,106 participants (mean age, 11.49 years; minimum age, 5 years; maximum age, 16 years), there were 36,449 males (50.5%) and 35,657 females (49.5%). From a psychopathological perspective, the motor symptoms node was associated with the sad node and the withdrawn node, while the cognitive symptoms node was linked to the nervous node and the self-conscious node. In terms of gender, males had stronger associations of the motor symptoms node with the sad node and the withdrawn node than females (P = 0.043), and weaker associations of the cognitive symptoms node with the nervous node than females (P = 0.027). In terms of growth stage, the adolescent group had stronger associations of the cognitive symptoms node with the nervous node and the self-conscious node than the child group (P = 0.016, 0.001). From DSM perspective, motor symptoms node were associated with sad node, and cognitive symptoms node were related to can't concentrate node, nervous node, and worthless node. With increasing age, there was an upward trend in the strength of the cognitive and motor symptoms node. CDS is closely linked to psychological and behavioral issues, especially internalizing problems, with differences observed by gender and growth stage. The connection between CDS and the affective, anxiety, and ADH symptoms is particularly pronounced.

Cognitive disengagement syndrome (sluggish cognitive tempo) and medical conditions: a systematic review and call for future research

Cognitive disengagement syndrome (CDS, previously referred to as sluggish cognitive tempo) is a unique set of symptoms distinct from ADHD inattentive symptoms that appear to be independently associated with neuropsychological and psychosocial outcomes in community and ADHD-specific samples of youth. However, our understanding of CDS in individuals with chronic or complex medical conditions is limited. The current systematic review is the first to summarize the literature on CDS prevalence rates and associations with neurocognitive and functional outcomes in youth with medical conditions, and to discuss areas of future research to guide clinical intervention. We conducted literature searches across four major databases and included studies assessing prevalence estimates, associations with neuropsychological and/or psychosocial functioning, or predictors of CDS in individuals with chronic or complex medical conditions. Twenty-five studies were identified and retained. Fifteen of sixteen studies reported elevations in CDS symptoms, though findings were mixed in studies comparing mean differences to typically developing youth. Seven studies provided inconsistent evidence for CDS being associated with neuropsychological or academic functioning, with six studies demonstrating consistent effects on psychosocial functioning. Finally, nine studies identified biological and sociodemographic factors associated with CDS, though almost all await replication. CDS symptoms are significantly elevated in youth with medical conditions and appear to be particularly linked with psychosocial functioning. Future research is needed to identify prevalence of CDS across a range of medical conditions, examine associations with neuropsychological and psychosocial functioning, and examine whether CDS impacts self-management.

Multi-method examination of cognitive disengagement syndrome and ADHD inattentive symptoms in relation to early adolescents' academic functioning

Cognitive disengagement syndrome (CDS), previously referred to as sluggish cognitive tempo, is a set of symptoms characterized by excessive daydreaming, mental fogginess, and slowed behavior/thinking. Studies examining the association between CDS and academic functioning have reported mixed findings and have relied upon limited measures of CDS, broad ratings of academic impairment, and/or focused only on elementary-aged children. The current study examined the relationship between CDS and academic functioning in adolescents using a comprehensive, multi-informant, multi-method design. Participants were 302 adolescents (Mage = 13.17 years; 44.7% female; 81.8% White; 52% with ADHD) recruited in the fall of their 8th grade. Above and beyond ADHD inattentive symptoms, CDS symptoms were related to poorer homework performance, lower math fluency, and lower daily academic motivation across multiple informants, and teacher-reported CDS symptoms were related to lower grades. Findings were not moderated by ADHD diagnosis, suggesting that associations between CDS and academic outcomes do not differ for adolescents with and without ADHD. Findings demonstrate that CDS symptoms are uniquely associated with daily academic difficulties as well as global indices of academic performance. These findings have implications for assessing and monitoring CDS symptoms in interventions aiming to improve the academic functioning in adolescents with and without ADHD.

Preliminary examination of ADHD inattentive and cognitive disengagement syndrome symptoms in relation to probe-caught mind-wandering during a sustained attention to response task

OBJECTIVE

The role of mind-wandering- periods of internally-directed distractibility - among patients with attention-deficit/hyperactivity disorder (ADHD) has recently garnered attention, though few studies have assessed mind-wandering using thought probes during a sustained attention to response task (SART) or examined the possible role of cognitive disengagement syndrome (CDS) symptoms. We examined whether parent- and/or teacher-reported ADHD-inattentive (ADHD-IN) or CDS symptoms were independently associated with probe-caught mind-wandering.

METHODS

Fifty-four children (ages 9-12; 35.2% female) completed a SART with thought probes inquiring about various on- and off-task thoughts, including mind-wandering and distraction. Questionnaires provided information on demographics, medication treatment, and parent- and teacher-reported ADHD-IN and CDS symptoms. Regression models were estimated separately by informant to examine whether ADHD-IN or CDS symptoms were uniquely associated with mind-wandering or distraction frequency during the SART.

RESULTS

Higher teacher-reported CDS ratings, but not ADHD-IN ratings, were uniquely associated with more probe-caught mind-wandering. No significant findings related to parent-reported symptoms or probe-caught distraction were observed.

CONCLUSIONS

These preliminary findings add to an emerging body of work pointing to CDS as more consistently or strongly associated than ADHD-IN with mind-wandering. Theoretical and clinical implications are discussed.

Examining cognitive disengagement syndrome in a psychiatric outpatient sample: Psychometric support and associations with internalizing symptoms and sleep problems

OBJECTIVE

The internal (structural) and external validity of a self-report measure of cognitive disengagement syndrome (CDS, formerly sluggish cognitive tempo) relative to a self-report measure of attention-deficit/hyperactivity disorder-inattention (ADHD-IN) was evaluated with adults from university outpatient psychiatric clinics in Turkey.

METHODS

A total of 274 outpatients (75.9% women; ages 18-64 years; Mage  = 31.06; SDage  = 10.84; 50.4% anxiety disorders; 41.6% depressive disorders; 2.9% ADHD; 1.5% sleep disorders; 0.7% eating disorders; 2.9% no mental disorder) completed self-report measures of CDS, ADHD-IN, ADHD-hyperactivity/impulsivity (HI), sleep problems, depression, and stress.

RESULTS

All 15 CDS symptoms measured by the Adult Concentration Inventory (ACI) showed convergent (moderate to high loadings on the CDS factor) and discriminant (loading close to zero on the ADHD-IN factor) validity. CDS also showed stronger first-order and unique associations than ADHD-IN with sleep problems, depression, anxiety, and stress, whereas ADHD-IN showed stronger first-order and unique associations than CDS with ADHD-HI.

CONCLUSION

This is the first study to provide support for the scores from this 15 item self-report measure of CDS by the ACI in a clinical sample of adults, with findings consistent with previous studies examining parent and teacher rating scale measures with the same 15 CDS symptoms. These findings provide additional support for usefulness of these 15 CDS symptoms as measured by the ACI to study CDS across various cultures.

[Clinical and neurophysiological manifestations of sluggish cognitive tempo in children]

OBJECTIVE

To study the clinical and neurophysiological features of children with low cognitive tempo (NCT), as well as the effectiveness of the drug Pantogam in the treatment of this pathology.

MATERIAL AND METHODS

A total of 90 children aged 8 to 10 years were examined. Of these, the main study group consisted of 30 children with NCT, the comparison group consisted of 30 children with a combined type of attention deficit hyperactivity disorder ADHD (ADHD-K), the control group consisted of 30 children without neuropsychiatric disorders. The study used clinical, neurophysiological (electroencephalography (EEG)) and parametric methods. The CMAS scale of apparent anxiety (The Children's Form of Manifest Anxiety Scale), the SNAP-IY scale (assessment of the degree of inattention, hyperactivity and impulsivity), the TOVA computer test (the Test of Variables of Attention), the scale «SCT» (Sluggish Cognitive Tempo) for assessing manifestations of low cognitive tempo, the «RAM» technique for quantifying working memory. Pantogam was used to treat patients at a dose of 750 mg per day for 8 weeks.

RESULTS

Patients with NCT are characterized by more pronounced attention disorders compared with healthy peers and with children with ADHD-K, and they have a decrease in mainly not selective attention, but the overall level of functional activity. Also, the group of children with NCT has an increased level of anxiety compared to the group of children with ADHD. A comparative analysis of the level of impulsivity showed that children with NCT are less characterized by a deficit in inhibition processes. According to the quantitative analysis of the EEG, specific changes in functional activity in the frontal and central regions of the cerebral cortex were revealed (a statistically significant increase in the ratio of absolute theta rhythm to beta1 rhythm, compared with other groups), reflecting insufficient cortical arousal and less focused neural states. When re-evaluating the condition of children with NCT after a course of therapy with Pantogam, an improvement in the form of a decrease in the degree of inattention, the severity of memory impairment and a decrease in reaction time was recorded in 60% of cases. According to quantitative EEG analysis, there was a significant decrease in the ratio of absolute theta rhythm to beta1 rhythm in the central leads of both hemispheres and in the parietal-temporal leads of the left hemisphere, indicating an increase in the level of overall activation of the cerebral cortex after a course of treatment.

CONCLUSION

Clinical and neurophysiological differences were revealed in patients with NCT and with combined ADHD. It has been shown that the use of Pantogam for the treatment of children with NCT leads not only to a decrease in the main manifestations of this disorder, but also to an improvement in the functional state of the brain.

Mind wandering in anxiety disorders: A status report

Many investigations have targeted the subject of worry in anxiety disorders. Worry can be regarded as a subtype of mind wandering (MW), which is undeliberate, perseverative, negatively-valenced, and mainly future-oriented. Nevertheless, until now only a few studies have explored the role of overall MW in the origin and course of anxiety disorders. To foster progress in this field, we briefly describe and discuss relevant studies addressing MW in subjects with anxiety disorders or symptoms or disorders associated with anxiety symptoms. Provisional synthesis suggests that: a) the overall amount of MW is positively correlated with anxiety symptoms; b) MW characteristics reflecting worry and rumination appear to be relevant in anxiety; c) comorbid depressive and ADHD symptoms may contribute to excessive MW in anxiety; d) MW-related therapeutic interventions may be useful as complementary treatments in anxiety disorders. However, more studies related to MW in anxiety disorders or symptoms are necessary to corroborate and extend these initial findings. Such investigations should ideally combine experience sampling with self-rating assessments of both MW and worry/rumination.

Psychopathology and mind wandering in young university students

Mind wandering has often been studied in relation to psychopathology. However, debates remain as to whether sluggish cognitive tempo, recently termed cognitive disengagement syndrome (CDS), and ADHD symptoms could be unique predictors of mind wandering. Therefore, this study was aimed at documenting the associations between CDS, ADHD symptoms and mind wandering while controlling for age, sex, internalized symptoms, and sleep. A sample consisting of university students (N = 60; aged between 17 and 32 years; 65% female) completed measures of CDS, ADHD symptoms, internalized functioning and insomnia. Mind wandering was also assessed using the 5-item Mind Wandering Questionnaire (MWQ) and thought sampling during a reading task. Multiple regression analyses show that while younger age and inattention were significant predictors of greater levels of self-reported mind wandering on the MWQ, sex, CDS, hyperactivity/impulsivity, internalized symptoms, and sleep were not. In addition, no variables were able to significantly predict spontaneous and deliberate mind wandering as assessed by thought sampling. These findings raise important questions regarding the equivalence between measures of state-level and trait-level mind wandering. The associations between ADHD, CDS and mind wandering in young adults are still unclear, but our findings highlight critical methodological considerations for future studies that might further our understanding of the relationship between task-unrelated thought and psychopathology.

Does Mind-Wandering Explain ADHD-Related Impairment in Adolescents?

Currently, diagnostic criteria for ADHD mainly reflect behavioral symptoms, neglecting internal phenomena like mind-wandering. Recent studies found that mind-wandering explains impairment beyond ADHD symptoms in adults. To better capture ADHD-related impairment in adolescents, we aimed to elucidate whether mind-wandering is associated with impairments that are prevalent in adolescents (i.e., risk-taking behavior, homework problems, emotional dysregulation, and general impairment) beyond ADHD symptoms. Furthermore, we sought to validate the Dutch translation of the Mind Excessively Wandering Scale (MEWS). We assessed a community sample of 626 adolescents on ADHD symptoms, mind-wandering, and the impairment domains. The Dutch MEWS had good psychometric properties. Mind-wandering was linked to general impairment and emotional dysregulation beyond ADHD symptoms, but was not linked to risk-taking behavior and homework problems beyond ADHD symptoms. Internal psychological phenomena such as mind-wandering may add to the behavioral symptoms of ADHD in explaining part of the impairment that adolescents with ADHD characteristics experience.

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.

Pharmacologic Management of Cognitive Disengagement Syndrome (CDS) and Implications for Attention-Deficit/Hyperactivity Disorder (ADHD) Treatment: Emerging Treatments and Recommendations for Future Research

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.

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.

Cognitive Disengagement Syndrome (Sluggish Cognitive Tempo) and Social Withdrawal: Advancing a Conceptual Model to Guide Future Research

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.

Spontaneous Thought Characteristics are Differentially Related to Heightened Negative Affect vs. Blunted Positive Affect in Adolescents: An Experience Sampling Study

Background

Mind-wandering has been linked to negative affect and depressive symptoms in adolescents. However, mind-wandering is an extremely broad and heterogenous cognitive construct. Some features of spontaneous thought may be related to increased negative affect, whereas others may improve affect, or have no emotional influence. We used ecological momentary assessment (EMA) to investigate the characteristics of spontaneous thoughts in adolescents and their differential relations with moment-to-moment affect.

Method

One-hundred and sixteen adolescents (ages 13-18; Typical Mood (TM) = 58; Low Mood (LM) = 58) completed 5 days (2-3 times/day) of EMA (total 1,037 surveys) assessing current positive and negative affect (PA and NA) and dimensions of spontaneous thought. Multilevel models tested the relation between thought characteristics and affect.

Results

Relative to the TM group, LM adolescents had a higher frequency of mind-wandering (38% vs. 56%) and negatively-valanced thoughts during episodes of mind-wandering (21% vs. 37%). Negatively-valenced, self-referential and past-oriented thoughts were each associated with higher NA, even when controlling for plausible confounds (e.g., engagement in an unpleasant activity or social interaction, depressive symptom severity). In contrast, task-focused and positively-valenced thoughts were uniquely linked to higher PA.

Conclusion

Characteristics of spontaneous thought - including temporal orientation, self-referential quality, and task-relatedness - were differentially related to NA vs. PA in adolescents. If replicated, these findings could inform more nuanced assessments of and targeted interventions for specific dimensions of mind-wandering contributing to high NA vs. blunted PA in teens.

Mind-Wandering and Childhood ADHD: Experimental Manipulations across Laboratory and Naturalistic Settings

The conceptual overlap between mind-wandering and attention-deficit/hyperactivity disorder (ADHD)-related impairments is considerable, yet little experimental research examining this overlap among children is available. The current study aims to experimentally manipulate mind-wandering among children with and without ADHD and examine effects on task performance. Participants were 59 children with ADHD and 55 age-matched controls. Participants completed a novel mind-wandering sustained attention to response task (SART) that included non-self-referential and self-referential stimuli to experimentally increase self-referential mind-wandering, reflected by increases in reaction time variability (RTV) following self-referential stimuli. The ADHD group participated in a classroom study with analogue conditions aimed at encouraging self-referential future-oriented thinking (free play/movie before and after class work) compared to a control condition (newscast) and a cross-over methylphenidate trial. The significant interaction between ADHD status and self-referential stimuli on SART performance indicated that self-referential stimuli led to greater RTV among children with ADHD (within-subject d = 1.29) but not among controls. Methylphenidate significantly reduced RTV among youth with ADHD across self-referential (d = 1.07) and non-self-referential conditions (d = 0.72). In the ADHD classroom study, the significant interaction between mind-wandering condition and methylphenidate indicated that methylphenidate led to higher work completion (ds > 5.00), and the free-play mind-wandering condition had more consistent detrimental effects on productivity (ds ≥ 1.25) than the movie mind-wandering condition. This study is the first to manipulate mind-wandering and assess effects among children with ADHD using a behavioral task. Results provide evidence that children with ADHD are uniquely susceptible to mind-wandering interference.

Longitudinal Association of Sluggish Cognitive Tempo with Depression in Adolescents and the Possible Role of Peer Victimization

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 (M_age = 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.

Systematic Review: Assessment of Sluggish Cognitive Tempo Over the Past Decade

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.

Disentangling the effects of attentional difficulties on fears of social evaluation and social anxiety symptoms: Unique interactions with sluggish cognitive tempo

Although fears of negative and positive social evaluation are hallmark cognitive features of social anxiety, attentional difficulties may exacerbate the relation between fears of social evaluation and social anxiety. Thus, the goal of the current study was to test whether two different types of self-reported attentional difficulties, specifically sluggish cognitive tempo (SCT) and attention-deficit/hyperactivity disorder (ADHD) inattention symptoms, moderate the relation between fears of social evaluation and social anxiety. Participants (N = 4756; Mage = 19.28 years; 72.7% female) enrolled in five universities across the United States completed self-report measures of fears of negative and positive evaluation and psychopathology symptoms. Results indicated a significant two-way interaction of fear of negative evaluation and SCT in relation to social anxiety symptoms, as well as a significant two-way interaction of fear of positive evaluation and SCT in relation to social anxiety symptoms. In both instances, the associations between fears of negative and positive evaluation in relation to social anxiety became increasingly stronger at higher levels of SCT. Conversely, the interactions between fears of negative and positive evaluation with ADHD inattentive symptoms were non-significant. These results are the first to report that self-reported SCT, but not ADHD inattentive symptoms, exacerbate the relation between fears of social evaluation and social anxiety, and suggest that attentional difficulties characteristic of SCT may prolong engagement in fears.
