RESUMO
BACKGROUND: Adolescents vary considerably in their circadian phase preference; those with greater "eveningness" (also known as "night owls") have later bedtimes, wake times, and peak arousal compared to those with greater "morningness." Prior research suggests that (a) greater eveningness is associated with worse academic, executive, and attentional functioning; and (b) adolescents with attention-deficit/hyperactivity disorder (ADHD) tend to be high in eveningness and to have deficits in these school-related constructs. However, few studies have examined circadian preference alongside two potential confounds-sleep duration and sleep quality-as predictors of daytime functioning, or whether the strength of associations differs across adolescents with and without ADHD. METHODS: Participants were 302 adolescents (Mage = 13.17 years; 44.7% female; 81.8% White); approximately half (52%) had ADHD. A multi-method, multi-informant design was used. Specifically, adolescents reported on their circadian preference, school night sleep duration, and sleep quality. Adolescents provided ratings of their academic motivation (intrinsic, extrinsic, and amotivation) and were administered standardized achievement tests in reading and math. Adolescents and parents completed ratings of daily life executive functioning (behavioral, emotion, and cognitive regulation), and they and teachers also provided ratings of ADHD inattentive symptoms. RESULTS: Above and beyond sleep duration, sleep quality, and covariates (sex, family income, pubertal development, medication use), greater eveningness was uniquely associated with poorer academic, executive, and attentional functioning across most measures. Sleep quality was uniquely associated with a handful of outcomes, and sleep duration was not significantly uniquely associated with any outcome in the regression analyses. ADHD status did not moderate effects. CONCLUSIONS: This study provides compelling evidence that poorer academic, executive, and attentional functioning are more closely associated with greater eveningness than with sleep duration or quality in adolescents. Findings suggest that targeting circadian preference may be important to reduce these problems in adolescents, especially in clinical samples such as ADHD for whom academic, executive, and attentional difficulties are exceptionally common.
RESUMO
Research has been inconclusive as to whether stimulant treatment causes or exacerbates sleep problems in adolescents with ADHD. This study examined sleep differences in adolescents with ADHD as a function of stimulant use. Participants were adolescents with ADHD (N = 159, ages 12-14). Parents reported on receipt of stimulant treatment (n = 92, 57.86%; n = 47 amphetamines, n = 45 methylphenidate). Adolescents wore actigraphs and completed daily diaries assessing sleep and daily use of stimulants for 2 weeks. Sleep parameters included daily-reported bedtime, sleep onset latency (SOL), sleep duration, daytime sleepiness, and difficulty waking the following morning; and actigraphy-measured sleep onset time, total time in bed, and sleep efficiency. We estimated between- and within-individual associations between stimulant medication use and sleep indices with all stimulants, after removing adolescents using sleep aids and weekend days, and as a function of stimulant type. Adolescent sleep did not differ between those receiving and not receiving stimulant treatment. Within individuals using stimulants, we largely observed no significant differences between medicated and unmedicated days, though findings were most often significant for school days only. Small effects were found indicating longer SOL, later sleep onset time, and more daytime sleepiness related to medication use. In contrast, there were slight improvements to sleep duration and sleep efficiency related to methylphenidate use, though methylphenidate was also associated with later sleep onset time and more daytime sleepiness. Given the inconsistent and small effects, findings suggest that stimulant medication may impact sleep, but does not appear to be a primary contributor to sleep problems in adolescents with ADHD.

Objective: College students engage in high rates of risky substance use. Standard college prevention strategies focus on providing feedback about current substance use behaviors and harm reduction strategies but do not address the underlying genetically-influenced risk factors impacting these behaviors. We created an online Personalized Feedback Program (PFP) for college students that targets genetically-influenced externalizing and internalizing risk pathways and provides personalized recommendations and campus resources. College students received personalized feedback on four risk domains (Sensation Seeking, Impulsivity, Extraversion, and Neuroticism). Methods: An open trial (n = 300) was conducted at a large public university in spring of 2021 to assess initial responses to the PFP and evaluate intentions related to future substance use and campus resource use. Results: 81% of students in the open trial reported they enjoyed the Personalized Feedback Program. Participants reported intending to use significantly more campus resources after completing the PFP. Among participants that drank, 39% reported they intended to decrease their alcohol consumption and 41% reported they intended to decrease the number of times they get drunk after completing the PFP; these intentions to reduce use after completing the PFP are higher than rates found in previous studies. Conclusion: Preliminary data indicate that the Personalized Feedback Program may be a complementary method to enhance current college substance use prevention programs.

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.
RESUMO
BACKGROUND: There is growing evidence for the role of circadian factors in adolescents' sleep and academic adjustment, with greater evening preference being linked to poorer academic functioning. However, studies have yet to evaluate this association prospectively in adolescence, nor have studies examined daytime sleepiness as a putative mechanism linking evening preference to poor academic functioning. The current study used a multi-informant design to test the prospective association of evening circadian preference, daytime sleepiness, and academic functioning (e.g., global academic impairment and grades) across 2 years in adolescence. As evening circadian preference, sleepiness, and academic problems are elevated in adolescents with ADHD, we used a sample enriched for adolescents with ADHD and explored whether ADHD moderated effects. METHOD: Participants were 302 adolescents (Mage = 13.17 years; 44.7% female; 81.8% White; 52% with ADHD). In the fall of eighth grade, adolescents reported on their circadian preference, and in the fall of ninth grade, adolescents and parents completed ratings of daytime sleepiness. In the middle of 10th grade, parents and teachers reported on adolescents' academic impairment and at the end of 10th grade, adolescents' grade point average (GPA) was obtained from school records. RESULTS: Above and beyond covariates (e.g., adolescent sex, ADHD status, medication, sleep duration) and baseline academic impairment, greater self-reported evening preference in 8th grade predicted increased parent ratings of academic impairment in 10th grade indirectly via adolescent and parent ratings of daytime sleepiness in 9th grade. Furthermore, evening preference in 8th grade predicted greater teacher ratings of academic impairment and lower average GPA in 10th grade via parent ratings of daytime sleepiness in 9th grade, controlling for covariates and baseline GPA. ADHD status did not moderate indirect effects. CONCLUSION: Findings underscore daytime sleepiness as a possible intervening mechanism linking evening preference to poor academic functioning across adolescence. Intervention studies are needed to evaluate whether targeting circadian preference and sleepiness improves academic functioning in adolescents.

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.

Changes in executive function (EF) occur during adolescence with several factors (e.g., parenting styles, socioeconomic status) influencing the development of EF abilities. These changes are important as EF has been strongly linked with a range of outcomes including academic achievement, job performance, and social-emotional well-being. However, few studies have examined variability in EF trajectories during this critical developmental period, or trajectories in samples known to have specific impairments with EF, such as adolescents diagnosed with attention-deficit/hyperactivity disorder (ADHD). The present study examined differential trajectories of three domains of parent-rated EF in 302 adolescents (167 males; Mage = 13.17 years) with and without ADHD (53.6% with ADHD) from grade 8 to 10. The study also explored whether adolescent ADHD, parent ADHD, and parents' own EF predicted EF trajectories in addition to the longitudinal relation between trajectories and academic outcomes. Findings suggest that adolescence is marked by significant variability in EF development due to factors such as ADHD status, parent ADHD, and parent EF ability. Additionally, adolescents who displayed poor EF abilities throughout middle and high school had significantly lower grade point averages and poorer parent-, teacher-, and self-reported academic outcomes. Implications for interventions targeting EF deficits among adolescents with and without ADHD are discussed.
RESUMO
OBJECTIVE: The aim of this study was to examine the costs and cost-effectiveness of a school-based training intervention delivered at varying levels of intensity with adolescents with attention-deficit/hyperactivity disorder (ADHD). Costs were examined in relation to post-treatment and 6-month follow-up effects of the Challenging Horizons Program (CHP), a training intervention for adolescents with ADHD. METHOD: A total of 326 middle-school students (71% male; 77% White) with ADHD were randomized to an after-school version of the CHP (CHP-AS), a less-intensive mentoring version (CHP-M), or routine community care. Detailed time logs were maintained throughout the study and were used to estimate costs associated with each condition. Student grade point average (GPA) and parent-rated ADHD symptoms and organization skills were collected at post-treatment and 6-month follow-up. RESULTS: The cost analysis revealed that CHP-AS was more costly per student than CHP-M, both in terms of overall costs and direct expenses to the school. However, CHP-AS was less costly per hour of intervention provided to the youth than CHP-M. Incremental cost-effectiveness ratios revealed that CHP-M may be the more cost-effective option for post-treatment effects, yet CHP-AS may be the more cost-effective option in the long term for sustained gains in organization skills and GPA. CONCLUSIONS: This study provides stakeholders important information to make decisions regarding allocation of finite monetary resources to meet their prioritized goals.

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.
RESUMO
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.

BACKGROUND: The field's understanding of the association between sluggish cognitive tempo (SCT) and sleep is severely limited by the lack of multi-method and multi-informant research designs that move beyond global ratings, often focused on a limited number of sleep-related domains, such as daytime sleepiness. The current study begins to address these limitations by using actigraphy, daily sleep diary, and self- and parent-report global ratings of sleep in adolescents, a developmental period marked by changes in SCT, sleep, and circadian function. As SCT and sleep are also associated with ADHD symptoms, we tested these associations in a sample of adolescents with and without ADHD. METHODS: Adolescents (N = 302; M age = 13.17 years, 44.7% female) with (n = 162) and without ADHD (n = 140) and parents completed global ratings of sleep and daytime sleepiness, and adolescents completed a measure of circadian preference. Adolescents also wore actigraphs for approximately two weeks, during which daily diaries were completed. RESULTS: Above and beyond demographic characteristics (i.e., sex, race, and family income), pubertal development, medication use, and ADHD group status, adolescents' self-reported SCT symptoms were uniquely associated with shorter sleep duration and later sleep onset per both actigraphy and daily diary. SCT symptoms were also uniquely associated with longer sleep onset latency and poorer overall sleep (per daily diary), more sleep/wake problems and daytime sleepiness (per adolescent rating), more difficulties initiating and maintaining sleep (per parent rating), and later eveningness preference (per adolescent rating). Nearly all significant effects remained in sensitivity analyses controlling for adolescent- or parent-reported ADHD symptom dimensions. CONCLUSIONS: Findings provide the strongest evidence to date for SCT being uniquely linked to poorer sleep, greater daytime sleepiness, and a later evening circadian preference across subjective and objective measures. Longitudinal studies are needed to evaluate predictive and bidirectional associations.

OBJECTIVE: Although peer difficulties and sluggish cognitive tempo (SCT) are related, studies have yet to examine environmental factors that may advance further understanding of this association. The current study tested whether peer difficulties, specifically social competence and peer victimization, interacted with school support, a component of school climate, in relation to adolescents' SCT symptoms. Further, we explored whether these relations would be differentially associated with SCT in adolescents with and without attention-deficit/hyperactivity disorder (ADHD). METHOD: Adolescents (N = 288; Mage = 14.08, 45% female, 82.6% White; 52% with ADHD) completed measures of social competence, peer victimization, school climate support, and SCT and ADHD inattentive (IN) symptoms. Parents also reported on adolescents' social competence, SCT, and ADHD-IN symptoms. RESULTS: Results indicated that adolescent and parent ratings of lower social competence were both associated with higher adolescent-reported SCT symptoms in the context of low, but not high, school support. Relational and nonphysical victimization were associated with higher self-reported SCT symptoms in the context of low school support. Lower adolescent- and parent-reported social competence were also related to higher parent-reported SCT symptoms, with these associations not moderated by school support. These results remained after controlling for demographics and ADHD-IN symptoms and were similar across adolescents with and without ADHD. CONCLUSIONS: Findings from the current study are the first to provide evidence that peer difficulties and school climate are jointly related to adolescents' self-reported SCT and underscore the importance of continued research investigating social adversity and environmental factors in relation to SCT.

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.
RESUMO
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.

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.

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.

OBJECTIVE: The objective of this study was to compare caffeine consumption in the morning, afternoon, and evening in adolescents with and without attention-deficit/hyperactivity disorder (ADHD) and examine associations with sleep functioning. METHODS: Participants were 302 adolescents (ages 12-14) with (N = 140) and without (N = 162) ADHD. Adolescents wore actigraph watches to assess total sleep time and wake after sleep onset and reported on sleep-wake problems and the number of caffeinated beverages consumed per day in the morning, afternoon, and evening. Parents reported on adolescents' difficulties initiating and maintaining sleep. Chi-square tests, odds ratios, and path analyses were conducted. RESULTS: Analyses controlled for sex, medication status, and pubertal development. Adolescents with ADHD were 2.47 times more likely to consume caffeine in the afternoon and evening than adolescents without ADHD. Path analyses indicated significant associations between afternoon caffeine use and more self-reported sleep problems for adolescents with and without ADHD, and an association between evening caffeine use and self-reported sleep problems only in adolescents with ADHD. Afternoon caffeine use was associated with parent-reported sleep problems in adolescents with ADHD only. Caffeine use was not associated with actigraphy-assessed sleep. CONCLUSION: This is the first study to show that adolescents with ADHD consume more caffeine than peers during later times of the day. Additionally, caffeine use is more consistently associated with poorer subjective sleep functioning in adolescents with ADHD. Pediatricians and mental health professionals should assess for caffeine use in adolescents with ADHD and co-occurring sleep problems.

OBJECTIVES: To examine patient- and provider-level factors associated with receiving attention-deficit/hyperactivity disorder (ADHD) medication treatment in a community care setting. We hypothesized that the likelihood of ADHD medication receipt would be lower in groups with specific patient sociodemographic (eg, female sex, race other than white) and clinical (eg, comorbid conditions) characteristics as well as physician characteristics (eg, older age, more years since completing training). STUDY DESIGN: A retrospective cohort study was conducted with 577 children (mean age, 7.8 years; 70% male) presenting for ADHD to 50 community-based practices. The bivariate relationship between each patient- and physician-level predictor and whether the child was prescribed ADHD medication was assessed. A multivariable model predicting ADHD medication prescription was conducted using predictors with significant (P < .05) bivariate associations. RESULTS: Sixty-nine percent of children were prescribed ADHD medication in the year after initial presentation for ADHD-related concerns. Eleven of 31 predictors demonstrated a significant (P < .05) bivariate relationship with medication prescription. In the multivariable model, being male (OR, 1.34; 95% CI, 1.01-1.78; P = .02), living in a neighborhood with higher medical expenditures (OR, 1.11 for every $100 increase; 95% CI, 1.03-1.21; P = .005), and higher scores on parent inattention ratings (OR, 1.06; 95% CI, 1.03-1.10; P < .0001) increased the likelihood of ADHD medication prescription. CONCLUSIONS: We found that some children, based on sociodemographic and clinical characteristics, are less likely to receive an ADHD medication prescription. An important next step will be to examine the source and reasons for these disparities in an effort to develop strategies for minimizing treatment barriers.

BACKGROUND: Children with attention-deficit/hyperactivity disorder (ADHD) experience greater sleep problems than their peers. Although adolescence is generally a developmental period characterized by insufficient sleep, few studies have used a multi-informant, multi-method design, to examine whether sleep differs in adolescents with and without ADHD. METHODS: Targeted recruitment was used to enroll an approximately equal number of eighth-grade adolescents (mean age = 13 years) with (n = 162) and without ADHD (n = 140). Adolescents and parents completed global ratings of sleep problems; adolescents, parents, and teachers completed ratings of daytime sleepiness. Adolescents wore actigraphs and completed a daily sleep diary for approximately 2 weeks. RESULTS: Adolescents with ADHD were more likely than adolescents without ADHD to obtain insufficient sleep on school days (per diary) and weekends (per diary and actigraphy). Adolescents with ADHD were also more likely to report falling asleep in class and to have stayed up all night at least twice in the previous 2 weeks (14% and 5% reported all-nighters for ADHD and comparison, respectively). In regression analyses controlling for a number of variables known to impact sleep (e.g. pubertal development, sex, medication use, having an externalizing, anxiety, or depression diagnosis), ADHD remained associated with shorter diary and actigraphy school night sleep duration, adolescent- and parent-reported daytime sleepiness, and parent-reported difficulties initiating and maintaining sleep and total sleep disturbance. Controlling for other variables, the odds of being classified with clinically elevated parent-reported sleep disturbance were 6.20 times greater for adolescents with ADHD. CONCLUSIONS: Findings provide some of the clearest evidence yet that adolescents with ADHD experience more sleep problems and sleepiness than their peers without ADHD. It may be especially important to assess for sleep problems in adolescents with ADHD and to evaluate whether existing sleep interventions are effective, or can be optimized, for use in adolescents with ADHD who also have sleep problems.

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.
