Growth of condition-related knowledge among youth with spina bifida: associations with neurocognitive functioning and self-management skills.

OBJECTIVE: This study aims to characterize the growth in condition-related knowledge in youth with spina bifida (SB), identify neurocognitive predictors of growth, and examine associations between growth in knowledge and subsequent levels of medical self-management skills. METHODS: Participants were recruited from a larger longitudinal study involving 140 youth with SB and caregivers, who completed questionnaires and interviews every 2 years over 8 years. The current study included the youth report of condition-related knowledge and medical self-management skills. Youth attention and executive functioning were assessed via parent and teacher reports and performance-based assessment. Latent growth curves were conducted in Mplus Version 8 (Múthen, L. K., & Múthen, B. O. [1998]. Mplus User's Guide. [Eighth]. Muthén & Muthén) to examine change over time in youth-reported condition-related knowledge. Neurocognitive variables were included as predictors of growth in knowledge and regression analyses were used to predict medical self-management skills from growth in condition-related knowledge. RESULTS: Youth condition-related knowledge increased linearly. Better youth performance on working memory and attention performance-based tasks predicted a higher intercept for condition-related knowledge at T1, but not slope. Teacher and parent reports of inattention and executive dysfunction were not consistent predictors of intercept and growth. Slope of condition-related knowledge was not predictive of subsequent youth self-management skills. CONCLUSIONS: Youth with SB gain condition-related knowledge over time. However, executive dysfunction and inattention may impede gains in condition-related knowledge. Thus, executive functioning supports, attention-related interventions, and psychoeducation may support condition-related knowledge gains and later medical self-management skills, but further research assessing family and cultural factors is needed.

Longitudinal transactions between negative urgency and fasting predict binge eating.

Fasting and negative urgency (the disposition to act rashly when distressed) are risk factors for binge eating. It may be that each influences the other over time to predict binge eating. OBJECTIVE: This study tested whether (1) fasting predicts binge eating through negative urgency, and (2) negative urgency predicts binge eating through fasting. METHOD: Path analysis and mediation tests were used to investigate objectives in n = 302 college women assessed three times over eight months. We controlled for each variable at the previous time point, and concurrent negative affect and body mass index at each time point. RESULTS: Time 1 (T1) fasting predicted elevated negative urgency three months later at Time 2 (T2) and T2 negative urgency predicted increases in binge eating five months later at Time 3 (T3). T2 negative urgency mediated the relationship between T1 fasting and T3 binge eating. T1 negative urgency predicted increases in T2 fasting, which then predicted increases in T3 binge eating. T2 fasting mediated the relationship between T1 negative urgency and T3 binge eating. DISCUSSION: Findings suggest fasting and negative urgency transact to predict binge eating among college women. Interventions targeting negative urgency may prevent or reduce both fasting and binge eating.

Academic motivation decreases across adolescence for youth with and without attention-deficit/hyperactivity disorder: Effects of motivation on academic success.

BACKGROUND: This longitudinal study examined growth trajectories of academic motivation in youth with and without attention-deficit/hyperactivity disorder (ADHD) across the important developmental transition from middle school to high school, and associations with academic success. Consistent with self-determination theory (SDT) of motivation, trajectories of amotivation, extrinsic motivation, and intrinsic motivation were modeled. METHODS: The study included a robust multi-method, multi-source assessment of academic outcomes, including homework performance ratings; reading and mathematics standardized test scores; and grade point average (GPA) obtained from school records. Participants included 302 adolescents (ages 12-14; Mage = 13.20) in eighth grade who were specifically recruited so that approximately half (n = 162) were diagnosed with ADHD and 140 adolescents comprising a comparison sample without ADHD. The sample was predominantly White (81.80%), with 7.90% identifying as bi/multiracial, 5.30% identifying as Black/African American, 4.60% identifying as Asian, and 0.30% identifying as Indigenous/Alaskan. RESULTS: Adolescents with ADHD had worse academic motivation at all timepoints. Growth curve analyses indicated the academic motivation of adolescents without ADHD decreased at faster rates across the transition to high school compared to adolescents with ADHD. However, for adolescents with ADHD, amotivation, extrinsic motivation, and intrinsic motivation each predicted GPA, with higher extrinsic and intrinsic motivation also predicting better homework performance and different aspects of math performance, whereas for youth without ADHD, only amotivation and extrinsic motivation predicted GPA. CONCLUSIONS: Intervention and school policy implications are discussed, including the importance of fostering autonomy and internal motivation, and consideration of whether current ADHD interventions primarily foster extrinsic motivation.

Comparing Cognitive Disengagement Syndrome Growth in Youth With and Without Spina Bifida.

OBJECTIVE: Cognitive disengagement syndrome (CDS; formally known as sluggish cognitive tempo), difficulties with social engagement, and lower levels of autonomy have been identified as maladaptive comorbidities in youth with spina bifida (SB). This study compared growth curves of CDS for youth with and without SB and examined whether these trajectories were associated with later functioning. METHODS: Longitudinal data spanning 8 years included youth with SB (n = 68, Mage = 8.34) and a demographically matched sample of typically developing (TD) peers (n = 68, Mage = 8.49). Adolescents, along with their caregivers and teachers, reported on youth social skills, behavioral functioning, and CDS. Growth curve models were examined by comparing CDS trajectories by SB status. RESULTS: Growth curves indicated that youth with SB had higher levels of teacher-reported CDS at ages 8 and 9, but growth curves were relatively stable for both groups. When predicting social skills, higher levels of teacher-reported (but not mother-reported) CDS at baseline predicted worse social functioning for both youth with and without SB in adolescence. For the slope findings, higher rates of mother-reported CDS over time predicted worse social skills (ß = -0.43) and lower levels of youth decision-making (ß = -0.43) for the SB group, while higher rates of teacher-reported CDS predicted worse social skills for the TD group. CONCLUSION: Next steps include understanding the impact that impaired social functioning and restricted autonomy have on youth with and without SB due to CDS to inform interventions. Additionally, advocacy for increased awareness of CDS-related impairment is needed, particularly for youth with chronic health conditions.

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.

Trajectories of Marital Satisfaction among Parents of Youth with Spina Bifida.

OBJECTIVE: This study examined marital satisfaction among parents of youth with spina bifida (SB) over an 8-year period and investigated the usefulness of the double ABCX model for understanding factors that predict change in marital satisfaction across child age. METHODS: Data from five time points of a longitudinal investigation of psychosocial outcomes in youth with SB were included. Mothers and fathers of children with SB (aged 8-17) reported on marital satisfaction and components of the double ABCX model. Change in marital satisfaction was examined across child age with components of the double ABCX model, as well as interactions between components, as predictors. RESULTS: Marital satisfaction was significantly higher in the present sample than in a normative sample of married couples. Although there were no significant changes in marital satisfaction for either parent as a function of child age, there was significant variability for the intercept and slope of maternal and paternal marital satisfaction within the sample. Family support predicted a higher intercept, and mental health symptoms predicted a lower intercept, for maternal and paternal marital satisfaction. More stressors and SB-related family stress predicted a lower intercept for paternal marital satisfaction. Family support and family stress attributed to SB moderated the relationship between child vulnerability and maternal marital satisfaction. Observed family cohesion and child psychosocial quality of life moderated the relationship between family stressors and paternal marital satisfaction. CONCLUSION: Findings demonstrate the usefulness of the double ABCX model for this population.

Cross-Lag Model of Medical Responsibility and Skills in Youth With Spina Bifida.

OBJECTIVE: This study examined bidirectional associations between mother- and father-reported medical responsibility and medical skill mastery in youth with spina bifida (SB). METHODS: Participants were 140 youth with SB and their parents who participated in three waves of a longitudinal study across four years (ages 8-15 years at Time 1). Mother- and father-report of both medical responsibility and medical skill mastery were used, and age and estimated intelligence quotient were included as covariates, in cross-lagged models. RESULTS: The cross-lagged model provided evidence for significant bidirectional associations between mother-reported medical responsibility and skill mastery across time (root mean square error of approximation=0.09, comparative fix index=0.97). These paths showed that higher levels of child responsibility predicted an increase in skill mastery and that higher levels of mastery predicted an increase in child responsibility across time. Moreover, based on mother-report, sharing of responsibility had stronger effects on increases in skill mastery (Time 1 to Time 2 ß=.25, Time 2 to Time 3 ß=.27) than skill mastery had on increases in child responsibility (Time 1 to Time 2 ß=.08, Time 2 to Time 3 ß=.07). The only significant cross-lagged path for father-report was from Time 1 skill mastery to Time 2 responsibility (ß=.34). CONCLUSIONS: Mothers perceive a bidirectional relationship between responsibility and skill mastery across time, whereas fathers appear to mainly consider how skills might affect a subsequent increase in responsibility sharing. Thus, it is important to consider both parents' perspectives when working to increase medical autonomy in youth with SB.

Factor Structure of Medical Autonomy Scales in Young People with Spina Bifida.

OBJECTIVE: The primary goal of this study was to examine the factor structure of a spina bifida (SB) medical responsibilities measure and a medical regimen skills scale across time in families of youth with SB. METHOD: One-hundred and forty youth with SB and their parents were assessed in both childhood/adolescence and adolescence/young adulthood. The Sharing of SB Medical Responsibilities Scale (SOSBMR) includes 34 items for which participants indicate who is responsible for each task. The SB Independence Survey (SBIS) is composed of 50 SB-specific medical skills items in yes-no format. Confirmatory factor analyses (CFA) were conducted to examine the factor structure of the SOSBMR and SBIS in childhood and adolescence (ages 8-15) and in adolescence/young adulthood (AYA; ages 16-25). RESULTS: One- and seven-factor CFAs were compared for both measures. For the SBIS, both mother- and father-report were used in childhood; self-report was employed for AYA. For the SOSBMR, only self-report was used for both age groups. Across each rater and time point, the seven-factor models of the SBIS and SOSBMR had adequate to excellent fit and reliability, indicating the ability to use each subscale. In addition, each of the corresponding subscales on the SOSBMR and SBIS were associated with each other across raters and time, showing good concurrent and predictive validity. CONCLUSIONS: From childhood to young adulthood, the subscales of the SOSBMR can be used to examine responsibility across multiple medical tasks and the SBIS can be used to assess medical regimen skills and mastery in young people with SB.

Social Skills and Medical Responsibility Across Development in Youth With Spina Bifida.

OBJECTIVE: To examine the predictive role of social skills in youth with spina bifida (SB) on growth in medical responsibility across development. METHODS: As part of a larger, longitudinal study, 140 youth with SB were assessed across four time points (ages 8-22 across time points). Mixed-effects models were investigated for change with: (a) no predictors (i.e., change in medical responsibility across age; time was examined using the participant's age, centered at 11.5 years); (b) social variables (i.e., observed social behaviors, parent- and teacher-reported social skills) as predictors; and (c) social variables as predictors with intelligence quotient, lesion level, and sex as covariates. RESULTS: Significant growth with age was identified for medical responsibility (p < .0001). Observed, parent-reported, and teacher-reported social skills did not significantly predict this growth; however, all three predicted the intercept for medical responsibility at 11.5 years of age (ps ≤ .047). Parent-reported social skills remained a significant predictor of the intercept at 11.5 years of age when including the covariates (p = .008). CONCLUSIONS: Children with SB who exhibited more positive social skills were more likely to a have higher level of medical responsibility in late childhood, but higher levels of social skills were not associated with a more rapid increase in responsibility over time. Identifying existing social strengths and promoting the practice of prosocial skills may have additional benefits to children with SB, including their acquisition of medical responsibility.

Do sluggish cognitive tempo symptoms improve with school-based ADHD interventions? Outcomes and predictors of change.

BACKGROUND: Sluggish cognitive tempo (SCT) is a construct that includes symptoms of slowness, excessive daydreaming, and drowsiness. SCT is often comorbid with attention-deficit/hyperactivity disorder (ADHD), and SCT symptoms are associated with significant academic impairment above the influence of ADHD. Despite the overlap between ADHD and SCT and associated impairments, no studies have evaluated how evidence-based psychosocial interventions for adolescents with ADHD impact symptoms of SCT. METHODS: This study examined whether SCT symptoms improved in a sample of 274 young adolescents with ADHD who were randomly assigned to an organizational skills intervention, homework completion intervention, or to a waitlist control. SCT intervention response was evaluated broadly in all participants and, specifically, for participants in the clinical range for SCT symptom severity at baseline. Change in ADHD symptoms of inattention, executive functioning, and motivation were examined as potential predictors of improvement in SCT. RESULTS: The two intervention groups were collapsed together for analyses because there were no significant differences in change in SCT symptoms. Multilevel modeling results indicate that parent-reported SCT symptoms significantly decreased when comparing the intervention group to waitlist control (d = .410). For adolescents with parent-reported clinical levels of SCT, the decrease in symptoms was more pronounced (d = .517). Self-reported SCT symptoms produced null results, though effect size calculations showed small improvement for the full sample (d = .313) and for the high-SCT group (d = .384). Change in behavior regulation executive functioning (d = .247), metacognitive executive functioning (d = .346), and inattention (d = .230) predicted change in parent-reported SCT symptoms. CONCLUSIONS: Although not specifically designed to decrease SCT symptoms, the ADHD interventions evaluated in this study resulted in significant improvements in parent-reported SCT with small to moderate effect sizes. Clinical implications and future directions are discussed, including development of interventions for adolescents with high levels of SCT.

Intraindividual variability of sleep/wake patterns in adolescents with and without attention-deficit/hyperactivity disorder.

BACKGROUND: Prior studies examining the sleep of adolescents with and without attention-deficit/hyperactivity disorder (ADHD) have relied on mean values such as average sleep duration, which masks intraindividual variability (IIV). The objective was to investigate whether adolescents with ADHD have greater IIV of sleep/wake patterns than adolescents without ADHD using actigraphy and daily sleep diaries. METHOD: Adolescents (ages 13.17 ± 0.40 years; 45% female) with (n = 162) and without (n = 140) ADHD were recruited from middle schools at two sites. Participants wore actigraphs and completed sleep diaries for an average of 2 weeks. RESULTS: Multilevel models were conducted with sex, sleep medication use, ADHD medication use, number of days with data, and social jetlag controlled for in analyses. For actigraphy, adolescents with ADHD had greater variability for time in bed, sleep onset and offset, and wake after sleep onset than adolescents without ADHD. For sleep diary data, adolescents with ADHD had greater variability in bedtime, wake time, sleep duration, sleep onset latency, sleep quality, and night wakings than adolescents without ADHD. Social jetlag was a significant predictor of variability in sleep measures based on both actigraph and daily diaries; however, ADHD status was not associated with social jetlag. CONCLUSIONS: This is the first study to show that adolescents with ADHD have more variable sleep/wake patterns than their peers using both objective and subjective sleep measures. IIV of sleep/wake patterns may be important for clinicians to assess and monitor as part of treatment. Research is needed to understand the mechanisms underlying increased IIV of sleep/wake patterns in adolescents with ADHD and potential consequences for daytime functioning.

Featured Article: Technology Use and Sleep in Adolescents With and Without Attention-Deficit/Hyperactivity Disorder.

OBJECTIVES: This study used a multi-informant approach to examine differences in types and rates of technology used by adolescents with and without attention-deficit/hyperactivity disorder (ADHD), associations between technology use and sleep/daytime sleepiness, and whether technology use was differentially related to sleep/daytime sleepiness in adolescents with and without ADHD. METHODS: Eighth graders with (n = 162) and without (n = 140) ADHD were recruited. Adolescents completed questionnaires assessing time spent using technology, sleep-wake problems, school-night time in bed, and daytime sleepiness. Parents and teachers reported on adolescents' technology use and daytime sleepiness, respectively. RESULTS: Adolescents with ADHD had significantly greater total technology, television/movie viewing, video game, and phone/video chatting use than adolescents without ADHD. Adolescents with ADHD engaged in twice as much daily video game use compared to those without ADHD (61 vs. 31 min). Controlling for medication use, ADHD status, pubertal development, sex, and internalizing symptoms, greater parent- and adolescent-reported technology use was associated with more sleep-wake problems and less time in bed. ADHD status did not moderate the relations between technology use and these sleep parameters. In contrast, ADHD status moderated the association between parent-reported technology use and teacher-reported daytime sleepiness, such that this association was significant only for adolescents with ADHD. CONCLUSIONS: Technology use, although more prevalent in adolescents with ADHD, is linked with more sleep problems and reduced school-night sleep duration regardless of ADHD status. Technology use is associated with teacher-rated daytime sleepiness only in adolescents with ADHD. Clinicians should consider technology usage when assessing and treating sleep problems.

Predicting academic impairment and internalizing psychopathology using a multidimensional framework of Sluggish Cognitive Tempo with parent- and adolescent reports.

Adolescents with Sluggish Cognitive Tempo (SCT) exhibit symptoms of slowness, mental confusion, excessive daydreaming, low motivation, and drowsiness/sleepiness. Although many symptoms of SCT reflect internalizing states, no study has evaluated the clinical utility of self-report of SCT in an attention-deficit/hyperactivity disorder (ADHD) sample. Furthermore, it remains unclear whether SCT is best conceptualized as a unidimensional or multidimensional construct. In a sample of 262 adolescents comprehensively diagnosed with ADHD, the present study used adolescent- and parent reports of SCT to evaluate the predictive utility of a general SCT factor from a bifactor modeling approach compared the utility of three specific SCT factors (slow, sleepy, and daydreamer) for predicting academic impairment and internalizing psychopathology. Overall, a multidimensional framework of SCT was supported, with the three SCT factors differentially predicting impairment and in one case (school grades), predicting impairment when the general factor did not. Consistent with prior research, SCT slow behaviors appear to be most strongly associated with impairment, predicting both academic impairment and internalizing psychopathology. Parent report of SCT was most useful for predicting academic functioning, whereas youth self-report was important for predicting anxiety and depression. Implications of the findings for the assessment and potential treatment of SCT are discussed.

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.

Participant compensation in health equity research: How equitable is it?

In this article, the authors highlight their experience in navigating outdated, inequitable policies at institutions and in advocating for changes that support health equity research with a focus on participant compensation. As two new assistant professors establishing their programs of health equity research, they call on colleagues to examine their practices of participant compensation while consider an intersectional and systems-level framework. Their goals are to develop culturally responsive interventions that bolster well-being and ameliorate harm caused by continuous exclusion or poor research methods. They highly recommend health equity researchers evaluate their institutions' research and financial practices to promote equitable payment options that are inclusive of everyone.

Working memory and cognitive flexibility predict growth trajectories of sluggish cognitive tempo in youth with spina bifida.

As sluggish cognitive tempo (SCT) shows similar inattention and neuropsychological dysfunction as youth with spina bifida (SB), it is important to examine whether neuropsychological functioning may affect the development of SCT in this population. Participants were 140 youth with SB and their parents who participated in five waves of a longitudinal study across eight years (ages 8-15 years at Time 1). At Time 1, teacher-, mother-, and father-report of SCT showed 9%, 8.3%, and 5.3% impairment in SCT respectively compared to other youth in the sample. Growth curves were used to examine changes over time in mother-, father-, and teacher-reported SCT. Four neurocognitive variables were included (attention, working memory, cognitive flexibility, plan/organize) as predictor variables of SCT growth and intercepts. Mother, father, and teacher-report of SCT were included in separate models. Age and shunt status were included as covariates in the growth models. Inattentive symptoms were also included as a covariate in working memory, shift, and plan/organize models. Worse working memory at Time 1 predicted an increase in mother-reported SCT symptoms over eight years (ß = -.28) and poorer cognitive shifting skills predicted higher rates of teacher-reported SCT over time (ß = -.61). All other neurocognitive variables predicted the intercept, but not the slope of SCT symptoms. Results indicate that worse neurocognitive functioning is associated with higher levels of SCT symptoms and that worse working memory and cognitive flexibility at baseline predicted an increase in SCT symptoms as youth with SB age. It may be important for clinicians to monitor and assess levels of SCT in youth with SB.

The Transition from Pediatric to Adult Health Care in Young Adults with Spina Bifida: Demographic and Physician-Related Correlates.

OBJECTIVE: This study examined the transition to adult health care for individuals with spina bifida (SB) and explored demographic and relational associations with transition status. METHOD: Young adults with SB (18-30; n = 326) were recruited to complete an anonymous, online survey. Frequencies of reported experiences, behaviors, and satisfaction with the transition to adult health care were examined. Nonparametric tests and exploratory hierarchical regressions were used to examine demographic and relational factors with physicians between those (1) who had and had not yet transitioned and (2) who did and did not return to pediatric care. RESULTS: Most of the sample reported having transitioned to adult health care, with three-quarters reporting that their primary physician is an adult primary care doctor. Individuals who had transitioned were more likely to be younger (p = 0.01) and to not have a shunt (p = 0.003). Beyond the effect of age and shunt status, relational factors with pediatric providers were not associated with transition (p > 0.1). After transition, over one-third reported returning to a pediatric provider. Those who did not return to pediatric care were more likely to have myelomeningocele, be a full-time student, and to not have a shunt (p < 0.001). Beyond the effect of age and shunt status, lower ratings of communication with adult providers were associated with a return to pediatric care (p = 0.04). CONCLUSION: The results highlight the need for additional research about barriers and facilitators to the transition to adult health care to target interventions that support this critical milestone in young adults with SB.

Peer Victimization and Poor Academic Outcomes in Adolescents With ADHD: What Individual Factors Predict Risk?

Objective: Examine individual factors associated with peer victimization (PV) in adolescents with attention-deficit/hyperactivity disorder (ADHD) and to examine the association between PV and educational outcomes. Method: Participants were 121 adolescents (Mage = 13.62, SD = 1.03; 89% boys) with diagnosed ADHD. Using path analysis, we tested whether general adolescent factors (ADHD symptoms, comorbid autism spectrum disorder, cognitive and social functioning, and age) were associated with experiences of PV, and associations between PV and academic outcomes. Results: Deficits in working memory (WM) and peer relationship problems were weakly and moderately associated with PV, respectively. PV was in turn was associated with adolescents' attitudes about school, academic competence, and academic achievement. Conclusion: Adolescents with poor social skills and/or WM difficulties who have ADHD may be particularly vulnerable to being victimized by peers. Failure to identify and manage PV during early adolescence may be connected to poor educational outcomes.

Sluggish Cognitive Tempo and Depressive Symptoms in Children and Adolescents Predict Adulthood Psychopathology.

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

Sluggish Cognitive Tempo in Adolescents with and without ADHD: Differentiation from Adolescent-Reported ADHD Inattention and Unique Associations with Internalizing Domains.

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