Predictors and Mechanisms of Resilience for High School Students with ADHD: A Prospective Longitudinal Study.

Attention-deficit/hyperactivity disorder (ADHD) has primarily been studied from a deficit-focused perspective. However, there are individuals with ADHD who exhibit resilience or a pattern of positive adaptation despite the risks associated with their diagnosis. The present study evaluated whether peer acceptance predicted resilience for adolescents with ADHD and if self-efficacy or a stress-is-enhancing mindset served as mechanisms of those relations. Participants included 113 comprehensively evaluated adolescents with ADHD (67% male) across three time-points (10th-12th grade). Mediation analyses revealed higher T1 peer acceptance significantly predicted higher resilience (ß = 0.24) 1.5-2 years later, with higher T2 self-efficacy (ß = 0.08) demonstrating a significant indirect effect of the association. A stress-is-enhancing mindset directly predicted resilience (ß = 0.15) but was not associated with peer acceptance nor mediated the association between peer acceptance and resilience. Present results are the first to provide longitudinal evidence for peer acceptance, self-efficacy, and a stress-is-enhancing mindset as important for promoting resilience among adolescents with ADHD.

Impacts of COVID-19 on the school experience of children and adolescents with special educational needs and disabilities.

This review of research conducted between March 2020-April 2023 summarizes the impact of COVID-19 on the learning and school experiences of children and adolescents with special educational needs and dis/abilities (SENDs) including youth with neurodevelopmental disorders, learning differences, intellectual, developmental, and other disabilities. This research highlights the far-reaching consequences of COVID-19, with the most detrimental effects experienced by students of color, those from under-resourced communities, and those with multiple marginalized identities, whose struggles with systemic inequities have been amplified by the pandemic. To date, most studies have been cross-sectional and utilized qualitative methods. Future research should examine long-term impacts and ways to promote growth in learning and social-emotional functioning among students with SENDs.

Impacts of COVID-19 quarantine and isolation on adolescent social functioning.

This review discusses research conducted globally between March 2020 and March 2023 examining the impact of the COVID-19 pandemic on adolescent social functioning, including their lifestyle, extracurricular activities, family environment, peer environment, and social skills. Research highlights the widespread impact, with largely negative effects. However, a handful of studies support improved quality of relationships for some young people. Study findings underscore the importance of technology for fostering social communication and connectedness during periods of isolation and quarantine. Most studies specifically examining social skills were cross-sectional and conducted in clinical populations, such as autistic or socially anxious youth. As such, it is critical that ongoing research examines the long-term social impacts of the COVID-19 pandemic, and ways to promote meaningful social connectedness via virtual interactions.

Clinical Change Mechanisms in the Treatment of College Students With ADHD: Trajectories and Associations With Outcomes.

The purpose of this study was to evaluate trajectories of response for the three theorized mechanisms of clinical change (knowledge, behavioral strategies, and adaptive thinking) associated with the Accessing Campus Connections and Empowering Student Success (ACCESS) intervention for college students with attention-deficit/hyperactivity disorder (ADHD) and their association with treatment outcomes. Participants included 250 college students comprehensively diagnosed with ADHD randomly assigned to ACCESS or to a delayed-treatment control who completed ratings at baseline, end of active treatment, and end of the maintenance phase of treatment (after two semesters). Growth mixture models (GMMs) were used to evaluate trajectories. Participants in ACCESS made significant gains in the use of behavioral strategies and trajectories were associated with large effect size improvements in measures of symptoms and functioning. Participants also made improvements in ADHD knowledge. However, only the knowledge trajectory with rapid improvement displayed significantly better outcomes. Only one trajectory group showed improvement in adaptive thinking with most ACCESS participants remaining stable across time. However, adaptive thinking trajectories were strongly related to both symptom and functional outcomes. ACCESS is associated with large gains in two of the three theorized clinical mechanisms of change, behavioral strategies and ADHD knowledge. Rapid improvement in behavioral strategies was associated with robust improvement in symptoms and functioning. Although improvements in the third mechanism, adaptive thinking, were small, they were strongly associated with outcomes demonstrating the importance of a cognitive-behavioral approach in treating college students with ADHD.

Longitudinal Change in Adolescent Depression and Anxiety Symptoms from before to during the COVID-19 Pandemic.

This study aimed to examine changes in depression and anxiety symptoms from before to during the first 6 months of the COVID-19 pandemic in a sample of 1,339 adolescents (9-18 years old, 59% female) from three countries. We also examined if age, race/ethnicity, disease burden, or strictness of government restrictions moderated change in symptoms. Data from 12 longitudinal studies (10 U.S., 1 Netherlands, 1 Peru) were combined. Linear mixed effect models showed that depression, but not anxiety, symptoms increased significantly (median increase = 28%). The most negative mental health impacts were reported by multiracial adolescents and those under 'lockdown' restrictions. Policy makers need to consider these impacts by investing in ways to support adolescents' mental health during the pandemic.

Prospective examination of psychological trauma among adolescents during the COVID-19 pandemic.

OBJECTIVE: This longitudinal study investigated the predictors of and changes in psychological trauma during the COVID-19 pandemic. METHOD: Participants included 236 adolescents (130 males; Mage = 16.74 years in spring 2020; 49.6% diagnosed with attention-deficit hyperactivity disorder; 16.1% diagnosed with an anxiety or depressive disorder) in the United States who completed online questionnaires at four timepoints (spring 2020, summer 2020, fall 2020, spring 2021). RESULTS: Repeated measures ANOVA showed that psychological trauma was highest during stay-at-home orders in spring 2020, and decreased for a majority of adolescents by the summer of 2020. However, ~20% of adolescents exhibited moderate-to-clinical levels of psychological trauma at each timepoint. Four groups were identified based on the presence of psychological trauma symptoms: (a) resilient group (normal range across all timepoints; 60.6%); (b) moderate fluctuating group (moderate range at 1 or more timepoints; 18.2%); (c) severe fluctuating group (clinical range at 1 or more timepoints; 14.0%); and (d) chronic psychological trauma group (moderate or clinical range across all timepoints; 7.2%). Females, adolescents with preexisting internalizing disorders, and participants whose families were most impacted by the pandemic were more susceptible to experiencing psychological trauma symptoms. CONCLUSIONS: Findings highlight at-risk populations and suggest that the COVID-19 pandemic resulted in psychological trauma symptoms for approximately 20% of adolescents at some point during the first year of the pandemic. There is critical need to provide mental health services to adolescents, such as through school-based services, to reduce the negative long-term psychological impact of the pandemic.

Development of a Web-Based Training Platform for School Clinicians in Evidence-Based Practices for ADHD.

Lack of training for school clinicians in evidence-based practices (EBPs) contributes to underutilization of such services for youth with attention-deficit/hyperactivity disorder (ADHD). Advances in web-based technology and videoconferencing have allowed for expanded access to and optimization of training. We describe the development and outcomes of a novel web-based platform for training school clinicians to gain skills in EBPs for school-age youth with ADHD. The training platform is adapted from an empirically supported, in-person training for a school-home behavioral intervention (Collaborative Life Skills program) and includes skill modules for working with teachers, parents, and students. Training methods include web-accessed manuals/handouts, skill example video clips, automated progress monitoring tools, and consultation/in-session coaching via videoconferencing. We gathered stakeholder qualitative and quantitative feedback during discovery and design phases of the iterative development. We then evaluated the usability, acceptability, fidelity and clinician and student outcomes of the remote training program. Focus group themes and qualitative feedback identified clinician preferences for remote training features (e.g., interactive, brief, role-plays/coaching methods), video tools (recorded samples of skills and therapy sessions), and progress monitoring tools (e.g., clear, easy to use). Clinician usability ratings of the platform were high with most components rated as moderately to very useful/easy to use. Clinician ratings of usability, fidelity implementing the treatment, and their EBP knowledge and confidence following training were favorable. Student's outcomes were similar to those achieved in prior studies of clinician in-person training. Results support the promise of remote, web-based clinician training for the dissemination of evidence-based practices.

Improving Adherence to Behavioral Parent Training for ADHD Using Digital Health Tools.

Behavioral Parent Training (BPT) is a well-established treatment for school-age children with ADHD but lack of parent adherence to prescribed parenting strategies limits treatment gains. Digital Health (dHealth) tools can be leveraged to target barriers to parent adherence but existing tools for parenting interventions are limited. New efforts to develop a dHealth tool to target adherence barriers including limited skill competence, EF processes, and low motivation/negative attitudes, are presented and recommendations for future technology-enhanced treatments are provided.

Rumination as a Mechanism of the Longitudinal Association Between COVID-19-Related Stress and Internalizing Symptoms in Adolescents.

The current prospective longitudinal study evaluated brooding rumination as an intervening mechanism of the association between COVID-19-related stress and internalizing symptoms during the first year of the pandemic. Attention-deficit/hyperactivity disorder (ADHD) status and adolescent sex were tested as moderators of the indirect effect. Adolescents with and without ADHD (N = 238; M age = 16.74) completed rating scales of COVID-19 stress and both adolescents and parents completed ratings scales of internalizing symptoms in May/June 2020 (T1). In October/November 2020 (T2), adolescents reported on their brooding rumination. Adolescents and parents reported on internalizing symptoms again in March/April 2021 (T3). Covariates included participant characteristics and baseline symptoms. T1 self-reported COVID-19-related stress was associated with increased T3 self-reported anxiety (ab = 0.10), self-reported depression (ab = 0.07), and parent-reported depression (ab = 0.09) via T2 brooding rumination. The indirect effect did not differ for adolescents with and without ADHD or for female and male adolescents. Brooding rumination may be one mechanism to target to promote the mental health adjustment of adolescents during periods of high stress of the COVID-19 pandemic and future stressors.

Adolescents with ADHD are at increased risk for COVID-19 vaccine hesitancy.

Identifying factors that influence adolescent intentions for COVID-19 vaccination is essential for developing strategic interventions to increase uptake, particularly in subgroups of at-risk adolescents. Attention-deficit/hyperactivity disorder (ADHD) in adolescence is characterized by difficulties regulating attention and behavior, social impairment, and impulsive risk-taking behaviors, which may impact vaccine hesitancy and vaccine uptake. This study examined hesitancy toward COVID-19 vaccines among adolescents with and without ADHD, and explored how ADHD status interacted with malleable social mechanisms and other social determinants of health in predicting vaccine hesitancy. Participants were 196 U.S. adolescents (44.4% male), 45.6% diagnosed with ADHD. Adolescents reported their confidence and willingness toward COVID-19 vaccines from March to May 2021. Adolescents with ADHD reported greater hesitancy and less confidence in COVID-19 vaccine safety compared to adolescents without ADHD (p < .01). Only 61.8% of adolescents with ADHD reported vaccine acceptance, compared to 81.3% of adolescents without ADHD. For all adolescents, those who identified as Black or Latinx and with lower family income had greater hesitancy and reduced confidence, whereas greater COVID-19 concerns, media use, and perceived negative impact on relationships was associated with greater vaccination willingness. Social contextual processes significantly interacted with ADHD status such that for adolescents without ADHD, concerns about COVID-19 were associated with increased confidence in vaccine safety. Being noncompliant with social distancing guidelines was associated with greater vaccine hesitancy, only for adolescents with ADHD. A concerted effort is needed to increase trust, confidence, and social relevance among adolescents, especially those with ADHD and from lower socio-economic backgrounds.

A preliminary examination of key strategies, challenges, and benefits of remote learning expressed by parents during the COVID-19 pandemic.

Among the many impacts of the Coronavirus disease (COVID-19) pandemic, one of the most dramatic was the immediate closure of in-person schooling in March/April 2020 when parents were faced with much greater responsibility in supporting their children's learning. Despite this, few studies have examined parents' own perspectives of this experience. The aims of this preliminary study were to (a) identify challenges, benefits, and useful strategies related to remote learning and (b) examine differences in findings across two countries, between parents of youth with and without attention-deficit/hyperactivity disorder (ADHD), and between parents of children and adolescents. To address these aims, parent responses to open-ended questions on the Home Adjustment to COVID-19 Scale (HACS; Becker, Breaux, et al., 2020) were examined across three studies conducted in the United States and Australia (N = 606, children: 68.5% male, ages 6-17 years). The challenges most frequently expressed by parents included the child's difficulty staying on task (23.8% of parents), lack of motivation (18.3%), remote learning factors (17.8%), and lack of social interaction (14.4%). The most frequently expressed strategy related to using routines and schedules (58.2%) and the biggest benefit was more family time (20.3%). Findings were largely consistent across countries, ADHD status, and age, with a few notable group differences. Given that the most common challenges involved child- (e.g., difficulties with staying on task and motivation), parent- (e.g., balancing remote learning with work responsibilities), and school- (e.g., remote instruction difficulties) related factors, there is a need for improved support across these systems going forward.

Co-Occurring Psychopathology Moderates Social Skills Improvement in a Randomized Controlled Trial of a Collaborative School-Home Intervention for Children with ADHD.

OBJECTIVE: Children with ADHD often exhibit marked impairment in their social skills, but evidence-based psychosocial interventions for ADHD have shown limited efficacy in remediating these deficits. Co-occurring psychopathology exacerbates social deficits in children with ADHD and is a plausible moderator of treatment response. To identify factors contributing to variable social skills treatment response, we examined co-occurring externalizing, depression, and anxiety symptoms as moderators of social skills outcomes in a randomized controlled trial of the Collaborative Life Skills (CLS) program, an evidence-based collaborative school-home ADHD intervention. METHOD: Participants were 159 children with ADHD (M age = 8.35 years, 28.3% female) at 27 schools in an urban public school district. Twenty-three schools were randomly assigned to CLS or usual services, with an additional four schools assigned to Spanish-adapted CLS or usual services. Multi-informant measures of co-occurring psychopathology and social skills were collected at baseline and post-treatment. RESULTS: Parent-rated externalizing and depression symptoms moderated treatment effects on social skills, whereby higher symptomatology in each domain was unrelated to social skills improvement in the CLS group but predicted worsening social skills in response to usual services. In contrast, teacher-rated anxiety moderated treatment effects on social skills, whereby higher anxiety predicted greater social skills improvement in response to CLS but was unrelated to social skills outcomes following usual services. CONCLUSIONS: Findings reflect novel evidence that child psychopathology domains exhibit unique moderating effects on social skills treatment response in children with ADHD. We discuss implications for optimizing evidence-based interventions to target social impairment in this population.

Coping with COVID-19: Longitudinal Impact of the Pandemic on Adjustment and Links with Coping for Adolescents with and without ADHD.

Understanding factors that foster resilience and buffer against the negative psychological impact of COVID-19 is critical to inform efforts to promote adjustment, reduce risk, and improve care, particularly for adolescents with neurodevelopmental disorders. This prospective longitudinal study addresses this gap by investigating the impact of the COVID-19 pandemic on adolescents' mental health and substance use, and by assessing specific positive coping strategies among adolescents with and without attention-deficit/hyperactivity disorder (ADHD). Using multi-group autoregressive cross-lagged path models, the present study explored the reciprocal influence of positive coping behaviors on multiple adjustment outcomes including mental health symptoms, substance use, stress, and worry. Participants included 238 adolescents (132 male participants; ages 15-17; 118 with ADHD). Parents provided ratings of adolescent routines, and adolescents provided ratings of coping behaviors and psychological adjustment in spring (May/June), summer (July/August), and fall (October/November) 2020. All models included the effects of adjustment at the prior timepoint as well as relevant covariates including adolescent race, ethnicity, sex, medication status, and family income. Adolescents with ADHD were at greater risk for experiencing increases in mental health symptoms and substance use throughout the pandemic, relative to adolescents without ADHD. The use of positive coping strategies and adolescent routines buffered against increases in substance use and mental health problems for adolescents with ADHD. These findings have important clinical and public policy relevance for parents, schools, and employers who may aim to prioritize keeping schedules as consistent as possible to promote healthy adjustment.

COVID-19 Resulted in Lower Grades for Male High School Students and Students With ADHD.

OBJECTIVE: Researchers have speculated that the COVID-19 pandemic may expand the academic performance gap experienced by at-risk students. We examined learning experiences during the 2020 to 2021 school year and the impact the pandemic has had on high school student grade point average (GPA), including predictors of change in GPA from 2019-2020 to 2020-2021. METHOD: Participants were 238 adolescents (55.5% male), 49.6% with attention-deficit/hyperactivity disorder (ADHD), in the United States. Adolescents reported on their GPAs via online surveys. RESULTS: GPA significantly decreased on average from 2019-2020 to 2020-2021 school year. ADHD status and biological sex significantly moderated change-students with ADHD and male students reported decreased GPA, whereas students without ADHD and female students' GPA did not change. Low income and Black/Latinx students had lower GPAs in both school years. CONCLUSION: It is imperative that additional supports be provided for at-risk students to help them catch up on missed learning during the pandemic.

Patterns of Parental Adherence and the Association to Child and Parenting Outcomes Following a Multicomponent School-Home Intervention for Youth With ADHD.

The goal of the present study was to evaluate the role of parent adherence in the Collaborative Life Skills (CLS) program, a multicomponent school-home intervention, for predicting child and parenting outcomes. A sample of 129 children (63% male; M age = 8.22, SD = 1.10; grades 2-5) with attention-deficit/hyperactivity disorder (ADHD) and their parents participated in CLS, which included 10 weekly behavioral parent training group sessions. Each week, parents provided information on their CLS skill use between sessions (at home) as part of the intervention. Outcome measures included parent and teacher ratings of child behavior and parenting at post-intervention and 6 months follow-up. Growth mixture models examining weekly parent skill use trajectories throughout the intervention significantly predicted parent- and teacher-reported outcomes including parent-rated child behavior, teacher-rated academic competence, and positive parenting behaviors. Fifty-two percent of parents displayed moderate skill use throughout the intervention, whereas the remaining parents had either low (20%) or high (28%) initial levels of use but demonstrated high skill utilization by the middle of the intervention. Results highlight the importance of examining individual differences in parents between session strategy use for behavioral parent training interventions targeting child and parenting outcomes.

Prospective impact of COVID-19 on mental health functioning in adolescents with and without ADHD: protective role of emotion regulation abilities.

BACKGROUND: The impact of chronic stressors like the COVID-19 pandemic is likely to be magnified in adolescents with pre-existing mental health risk, such as attention-deficit/hyperactivity disorder (ADHD). This study examined changes in and predictors of adolescent mental health from before to during the COVID-19 pandemic in the Southeastern and Midwestern United States. METHODS: Participants include 238 adolescents (132 males; ages 15-17; 118 with ADHD). Parents and adolescents provided ratings of mental health symptoms shortly before the COVID-19 pandemic and in spring and summer 2020. RESULTS: Adolescents on average experienced an increase in depression, anxiety, sluggish cognitive tempo, inattentive, and oppositional/defiant symptoms from pre-COVID-19 to spring 2020; however, with the exception of inattention, these symptoms decreased from spring to summer 2020. Adolescents with ADHD were more likely than adolescents without ADHD to experience an increase in inattentive, hyperactive/impulsive, and oppositional/defiant symptoms. Adolescents with poorer pre-COVID-19 emotion regulation abilities were at-risk for experiencing increases in all mental health symptoms relative to adolescents with better pre-COVID-19 emotion regulation abilities. Interactive risk based on ADHD status and pre-COVID-19 emotion regulation abilities was found for inattention and hyperactivity/impulsivity, such that adolescents with ADHD and poor pre-COVID-19 emotion regulation displayed the highest symptomatology across timepoints. Lower family income related to increases in inattention but higher family income related to increases in oppositional/defiant symptoms. CONCLUSIONS: The early observed increases in adolescent mental health symptoms during the COVID-19 pandemic do not on average appear to be sustained following the lift of stay-at-home orders, though studies evaluating mental health across longer periods of time are needed. Emotion dysregulation and ADHD increase risk for sustained negative mental health functioning and highlight the need for interventions for these populations during chronic stressors. Results and clinical implications should be considered within the context of our predominately White, middle class sample.

Prospective examination of adolescent sleep patterns and behaviors before and during COVID-19.

STUDY OBJECTIVES: To prospectively examine changes in adolescent sleep before and during the COVID-19 pandemic in adolescents with and without ADHD. METHODS: Participants were 122 adolescents (ages 15-17; 61% male; 48% with ADHD). Parents reported on adolescents' sleep duration and difficulties initiating and maintaining sleep (DIMS); adolescents reported on sleep patterns, sleep duration, delayed sleep/wake behaviors, and daytime sleepiness before (September 2019 to February 2020) and during (May-June 2020) COVID-19. Adolescents also reported on their health behaviors, COVID-19-related negative affect, and difficulties concentrating due to COVID-19. RESULTS: Parents reported adolescents had more DIMS during COVID-19 than before COVID-19, with clinically elevated rates increasing from 24% to 36%. Both bedtimes and waketimes shifted later during COVID-19, and adolescents reported more delayed sleep/wake behaviors. Adolescents also reported less daytime sleepiness and longer school night sleep duration during COVID-19. In considering differences between adolescents with and without ADHD, adolescents with ADHD did not experience an increase in school night sleep duration and were less likely to obtain recommended sleep duration during COVID-19. In the full sample, controlling for ADHD status, COVID-19-related sadness/loneliness was associated with increases in DIMS, and spending less time outside and more COVID-19-related worries/fears were associated with increases in delayed sleep/wake behaviors during COVID-19. CONCLUSIONS: COVID-19 had negative and positive impacts on adolescent sleep. Adolescents with ADHD did not experience the benefit of increased school night sleep duration during COVID-19 like adolescents without ADHD. Negative affect and health behaviors may be useful intervention targets for reducing negative impacts of COVID-19 for adolescent sleep.

An RCT of a CBT Intervention for Emerging Adults with ADHD Attending College: Functional Outcomes.

Objective: The current study reports functional outcomes from a multi-site randomized trial of a cognitive-behavioral treatment program for college students diagnosed with ADHD.Methods: A sample of emerging adults (N = 250; ages 18 to 30) currently attending college were comprehensively evaluated and diagnosed with ADHD (M age = 19.7; 66% female, 6.8% Latino, 66.3% Caucasian). Participants were randomized to either a two-semester intervention (Accessing Campus Connections and Empowering Student Success (ACCESS)) or a delayed treatment condition. Participants were assessed with measures of academic, daily life, and relationship functioning prior to treatment, at the end of the first semester, and after the second semester of treatment.Results: Multi-group latent growth curve models revealed moderate effect size improvements on self-report measures of study skills and strategies, as well as on self-report measures of time management, daily functioning, and overall well-being for participants in ACCESS. Importantly, treatment effects were maintained or increased in some cases from the end of the first semester to the end of the second semester. Improvements in self-reported interpersonal functioning were not significantly different across condition and neither condition demonstrated significant change over time in educational record outcomes (GPA and number of credits earned).Conclusions: ACCESS appears to promote improvements in self-reported general well-being and functioning, time management, and study skills and strategies. However, improvements in interpersonal relationships and objective academic outcomes such as GPA were not observed. Clinical implications and future directions for treating ADHD on university and college campuses are discussed.

Preschool Neuropsychological Predictors of School-aged Sluggish Cognitive Tempo and Inattentive Behaviors.

Sluggish cognitive tempo (SCT) is characterized by excessive daydreaming, slowed thinking, and mental confusion and 'fogginess'. A growing body of research supports the empirical differentiation of sluggish cognitive tempo (SCT) from the inattentive (IN) behaviors that characterize attention-deficit/hyperactivity disorder (ADHD). Further SCT and IN are uniquely associated with clinical correlates across academic, social, and emotional domains; however, there is limited understanding of how neuropsychological functioning contributes to SCT and/or IN behaviors. The two broad domains of neuropsychological functioning that have been most frequently examined in relation to SCT behaviors are processing speed and executive functions (EF). The present study tested whether EF and processing speed measured when children were on average age five years were predictive of teacher-rated IN and SCT behaviors in 1st - 3rd grades. Participants included 1,022 children from the Family Life Project, an ongoing prospective longitudinal study of child development in low-income, non-metropolitan communities. EF and processing speed uniquely made independent contributions to the prediction of IN and SCT. In secondary analyses that focused on specific facets of EF and processing speed, inhibitory control and working memory abilities predicted lower IN but not SCT behaviors, whereas slower processing speed significantly predicted both greater SCT and IN behaviors. These results are discussed as they inform developmental models of SCT and IN.

Testing the Longitudinal Structure and Change in Sluggish Cognitive Tempo and Inattentive Behaviors From Early Through Middle Childhood.

Previous studies have demonstrated that sluggish cognitive tempo (SCT) behaviors are empirically distinct from inattentive (IN) behaviors that are used to define attention-deficit/hyperactivity disorder. However, most studies used cross-sectional designs during middle childhood. Using parent and teacher ratings from the Family Life Project (N = 1,173), we investigated the factor structure, longitudinal measurement invariance, developmental trajectories, and predictors of developmental change in SCT and IN from age 3 years through Grade 5. SCT and IN were dissociable but correlated constructs that exhibited longitudinal invariance for both informants. Mean levels of SCT increased modestly with age, becoming more prominent between age 5 years and first grade, while IN was more stable. Lower parental education was associated with higher parent- and teacher-reported SCT, male sex was associated with higher teacher-reported IN, and African American race was associated with higher teacher-reported IN but lower teacher-reported SCT. These findings support the validity of SCT starting in early childhood.
