Children and adolescents (henceforth "children") with both attention-deficit/hyperactivity disorder (ADHD) and anxiety experience greater difficulties than children with either alone, though qualitative methodologies are yet to be used to understand the challenges this population experiences. We aimed to explore parent-reported daily impacts of co-occurring anxiety in children with ADHD (ages 8–13 years). Participants were enrolled in an Australian trial evaluating an adapted anxiety intervention and were eligible if their child met diagnostic criteria for ADHD plus separation, social, and/or generalized anxiety disorder. A baseline measure of life impacts associated with child anxiety captured situations parents reported were difficult, due to their child's anxiety. Reflexive thematic analysis of free-text responses (N = 203) facilitated new insights via inductively generating key themes. Three overarching themes highlighted (1) child difficulties with everyday situations and processes due to their anxiety; (2) the nature of the child's anxiety being pervasive and unrelenting; and (3) the strain placed on the child's family system. This study enhances understanding of daily impacts associated with co-occurring anxiety and ADHD and may contribute to an improved understanding of support needs. Results reiterate the need to identify co-occurring difficulties in children with ADHD and support both children and their families. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic has markedly impacted functioning for children and adolescents including those with attention-deficit/hyperactivity disorder (ADHD). We explored home learning difficulties (HLD) during COVID-19 restrictions in Australian children (aged 5–17) with ADHD, aiming to: (1) describe home learning experiences, and (2) examine associations between child anxiety (i.e., concurrent anxiety symptoms and pre-existing anxiety disorder status) and HLD. Baseline data from the longitudinal ADHD COVID-19 Survey were used (n = 122). Parents reported on school factors and HLD; pre-existing anxiety and co-occurring difficulties; anxiety, ADHD, and oppositional symptoms; demographics; and medications. Parents retrospectively reported more children often looked forward to school pre-pandemic, than during the pandemic. Anxiety symptoms, but not pre-existing anxiety disorder status, were associated with HLD after accounting for covariates. ADHD inattention symptoms were also associated with HLD. Results support recommendations to continue pre-pandemic supports to assist with ADHD symptoms during home learning, and strategies/supports for families are discussed. [ABSTRACT FROM AUTHOR]

Background: Sleep difficulties are common in children with attention‐deficit/hyperactivity disorder (ADHD). However, sleep problems are multifaceted and little is known about the variation in sleep difficulties across children with ADHD. We examined the profiles of sleep difficulties in children with ADHD and associated clinical factors (e.g. co‐occurring mental health conditions, stimulant use and parent mental health). Methods: Data from two harmonised studies of children with ADHD (total: N = 392, ages 5–13 years) were used. Parents completed measures of children's sleep, co‐occurring mental health conditions and their own mental health. Both parents and teachers completed measures of child ADHD symptoms and emotional and conduct symptoms. Latent profile analysis was used to identify sleep profiles, and multinomial logistic regression assessed clinical correlates of the groups. Results: Five sleep profiles were identified: (a) insomnia/delayed sleep phase (36%), (b) generalised sleep difficulties at sleep onset and overnight (25%), (c) high anxious/bedtime resistance difficulties (11%), (d) overnight sleep difficulties including obstructive sleep apnoea and parasomnias (5%) and (e) no sleep difficulties (22%). Compared with the group without sleep difficulties, the generalised, anxious/bedtime resistance and insomnia/delayed sleep phase sleep had greater parent‐reported emotional and conduct symptoms, co‐occurring anxiety and increased parent mental health difficulties. The generalised and anxious/bedtime resistance groups also had greater parent‐reported ADHD symptoms, with the anxious/bedtime resistance sleep group also having more frequent co‐occurring depression and teacher‐reported emotional symptoms. Conclusions: The sleep difficulties experienced by children with ADHD are varied. Supports to help children with ADHD need to consider the particular profiles of sleep difficulties experienced and broader clinical characteristics. Tailored intervention approaches are likely needed (including a need to address parent mental health). [ABSTRACT FROM AUTHOR]

Background: Attention deficit hyperactivity disorder (ADHD) and irritability commonly co‐occur, and follow similar developmental trajectories from childhood to adolescence. Understanding of the developmental relationship between these co‐occurrences is limited. This study provides a longitudinal assessment of how ADHD diagnostic status and symptom patterns predict change in irritability. Methods: A community sample of 337 participants (45.2% ADHD), recruited for the Childhood Attention Project, completed the Affective Reactivity Index (ARI) to measure irritability at baseline (mean age 10.5 years) and follow‐up after 18‐months. Latent change score models were used to assess how (a) baseline ADHD vs. control group status, (b) baseline symptom domain (inattention, hyperactivity–impulsivity) and (c) longitudinal change in ADHD symptom severity predicted change in irritability. Results: Irritability was significantly higher among the ADHD group than controls; however, change in irritability over time did not differ between groups. When assessed across the entire cohort, change in irritability was predicted by higher symptom count in the hyperactive–impulsive domain, but not the inattentive domain. Greater declines in ADHD symptoms over time significantly predicted greater declines in irritability. Baseline ADHD symptom severity was found to significantly predict change in irritability; however, baseline irritability did not significantly predict change in ADHD symptoms. Conclusions: ADHD symptoms—particularly hyperactive–impulsive symptoms—predict the degree and trajectory of irritability during childhood and adolescence, even when symptoms are below diagnostic thresholds. The use of longitudinal, dimensional and symptom domain‐specific measures provides additional insight into this relationship. [ABSTRACT FROM AUTHOR]

This pilot randomised controlled trial evaluated the acceptability and feasibility of a psychological intervention to manage severe irritability in children and adolescents. Children with severe irritability (9–14 years; 42% male) were randomised to receive six sessions of Collaborative & Proactive Solutions (CPS) or usual clinical care. The primary outcome was acceptability and feasibility of the intervention (participant enrollment, drop-out, intervention session attendance). Key secondary outcomes assessed 4-month post-randomisation included child irritability, quality of life, executive functioning, parent mental health and family functioning. Twelve children enrolled in the study (52% uptake). All participants in the CPS group attended ≥2 intervention sessions, and one participant in the usual care group was lost to follow-up. Compared to usual care, the CPS group had improvements in child irritability (Effect Size (ES): −0.4), quality of life (ES: 0.4), executive functioning (ES: −0.4), and family functioning (ES: −0.7). It is acceptable and feasible to deliver CPS to severely irritable children and adolescents. Preliminary evidence suggests this non-pharmacological intervention improves important areas of functioning for severely irritable children. The trial was prospectively registered on 11 October 2017 with the Australian New Zealand Clinical Trials Registry (: ACTRN12617001445369). [ABSTRACT FROM AUTHOR]

Objectives: Policy makers in developed countries have long considered the education system an avenue for supporting mental health care for children. Whilst educators have identified many challenges to providing this support (e.g. non-core role, stigma, overcrowded curriculum), understanding clinicians' views on the role of educators and schools and how clinicians and schools could work together to achieve good mental health outcomes are important questions. However, clinician voices in how schools and health should work together for children's mental health care are frequently missing from the debate. We aimed to report clinicians' views about how the education system could support student's mental health and improve access to mental health care for children and adolescents. Methods: 143 clinicians (approximately 35 each of child and adolescent psychiatrists, pediatricians, child psychologists and general practitioners (GPs)) from the states of Victoria and South Australia participated in semi-structured phone interviews between March 2018 and February 2019. Inductive content analysis was applied to address the broad study aims. Findings: Key themes emerged: (1) The role of schools in supporting individual children; (2) School based programs to support children and families; and (3) Challenges of implementing these suggestions. Clinicians across all professional groups suggested the education system could play an important role in improving access to mental health services through harnessing existing staff or co-locating mental health clinicians. They also suggested schools could identify at risk children and implement coping and social skills programs. Conclusions: Schools and educators could play a key role in prevention and early intervention of children's mental health problems. However, before recommending exactly how to do this, key evidence gaps need to be addressed. [ABSTRACT FROM AUTHOR]

Irritability has been associated with aberrant patterns of neural activation, yet little is known about structural brain correlates of irritability. As such, we aimed to investigate associations between irritability and gray matter volume (GMV) in a community sample of children enriched for irritability. The sample comprised children (n=162) aged 9-11 years with and without Attention-Deficit/Hyperactivity Disorder (ADHD), participating in a cohort study with magnetic resonance imaging data available. Mixed effects linear regression analyses tested the associations between irritability symptoms and regional GMV (extracted using Freesurfer). Irritability was associated with smaller gray matter volume across multiple brain regions implicated in executive functioning, and emotion and reward processing including frontal regions and the cingulate.

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 (M age = 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. [ABSTRACT FROM AUTHOR]

Objectives: Despite substantial investment by governments, the prevalence of mental health disorders in developed countries remains unchanged over the past 20 years. As 50% of mental health conditions present before 14 years of age, access to high-quality mental health care for children is crucial. Barriers to access identified by parents include high costs and long wait times, difficulty navigating the health system, and a lack of recognition of the existence and/or severity of the child's mental health disorder. Often neglected, but equally important, are clinician views about the barriers to and enablers of access to high-quality mental health care. We aimed to determine perspectives of Australian clinicians including child and adolescent psychiatrists, paediatricians, psychologists and general practitioners, on barriers and enablers within the current system and components of an optimal system. Methods: A total of 143 clinicians (approximately 35 each of child and adolescent psychiatrists, paediatricians, child psychologists and general practitioners) from Victoria and South Australia participated in semi-structured phone interviews between March 2018 and February 2019. Inductive content analysis was applied to address the broad study aims. Findings: Clinician-identified barriers included multi-dimensional family factors, service fragmentation, long wait times and inadequate training for paediatricians and general practitioners. Rural and regional locations provided additional challenges but a greater sense of collaboration resulting from the proximity of clinicians in rural areas, creating an opportunity to develop support networks. Suggestions for an optimal system included novel ways to improve access to child psychiatry expertise, training for paediatricians and general practitioners, and co-located multidisciplinary services. Conclusion: Within the current mental health system for children, structural, training and workforce barriers prevent optimal access to care. Clinicians identified many practical and systemic ideas to improve the system. Implementation and evaluation of effectiveness and cost effectiveness of these ideas is the next challenge for Australia's children's mental health. [ABSTRACT FROM AUTHOR]

Aim: To determine: (i) wait times and out‐of‐pocket costs for children attending private specialists for initial mental health appointments; and (ii) whether these differed between specialists working in metropolitan versus rural areas and in low, medium and high socio‐economic areas. Methods: Prospective secret shopper study whereby a researcher posed as a parent seeking an appointment for her child with anxiety or attention‐deficit/hyperactivity disorder. We contacted 317 private paediatrician, psychiatrist and psychologist practices in Victoria and South Australia between 12 March and 5 May 2019. Results: One third (29.8%) of private practices were closed to new referrals. The average wait times for paediatricians, psychiatrists, and psychologists were 44, 41 and 34 days, respectively. Average out‐of‐pocket costs quoted were AU$120 for paediatricians, AU$176 for psychiatrists and AU$85 for psychologists. Conclusion: Parents face extensive wait times and substantial out‐of‐pocket costs when seeking private mental health services for their child. [ABSTRACT FROM AUTHOR]

Aims: Severe behavioural problems (SBP) are a major contributor to morbidity in children with intellectual disability (ID). Medications used to treat SBP in ID are associated with a high risk of side effects. Cannabidiol has potential therapeutic effects in SBP. This pilot study aimed to investigate the feasibility of conducting a randomised placebo‐controlled trial of cannabidiol to reduce SBP in children with ID. Methods: This is a double‐blind, placebo‐controlled, two‐armed, parallel‐design, randomised controlled trial of cannabidiol in children aged 8–16 years with ID and SBP. Participants were randomised 1:1 to receive either 98% cannabidiol in oil (Tilray, Canada) or placebo orally for 8 weeks. The dose was up‐titrated over 9 days to 20 mg/kg/day in two divided doses, with a maximum dose of 500 mg twice/day. The feasibility and acceptability of all study components were assessed. Results: Eight children were randomised, and all completed the full study protocol. There were no serious adverse events or drop‐outs. Protocol adherence for key study components was excellent: study visits 100%, medication adherence 100%, blood tests 92% and questionnaire completion 88%. Parents reported a high degree of acceptability with the study design. All parents reported they would recommend the study to other families with children with similar problems. There was an efficacy signal in favour of active drug. Conclusions: The findings suggest that the study protocol is feasible and acceptable to patients with ID and SBP and their families.

Objective: Mindfulness is defined as paying attention in a particular way: on purpose, in the present moment, and nonjudgmentally and these behaviors can be applied to parenting. Thus far, it is not understood whether mindful parenting (MP) differs in parents of children with and without attention-deficit/hyperactivity disorder (ADHD), and how MP relates to other parenting practices and children's self-regulation.Methods: This study examined the relationships between MP, parenting behaviors and children's self-regulation in 120 families with child ADHD (85% male; mean age = 11.93) and 105 control families (62% male; mean age = 11.98). Parents completed measures of MP (Interpersonal Mindfulness in Parenting Scale), parenting behaviors (parenting warmth, consistency, and anger assessed with the Longitudinal Study of Australian Children measures), psychological distress (Kessler 6), and children's self-regulation (Social Skills Improvement System-self-control subscale).Results: When compared with controls, parents of children with ADHD reported significantly lower MP. Higher MP was associated with lower levels of parent psychological distress, higher levels of parenting warmth and consistency, lower levels of parenting anger, and higher child emotion self-regulation in both groups. In mediation analyses, MP was indirectly associated with child emotion self-regulation through lower parenting anger, with the model accounting for 55% of the variance in child self-regulation.Conclusions: MP is a useful construct for understanding parent behaviors, and children's emotion self-regulation.

Background: Over the past 20 years the prevalence of child and adolescent mental disorders in high-income countries has not changed despite increased investment in mental health services. Insufficient contact with mental health services may be a contributing factor; however, it is not known what proportion of children have sufficient contact with health professionals to allow delivery of treatment meeting minimal clinical practice guidelines, or how long children experience symptoms prior to receiving treatment.Aims: To investigate the level of mental healthcare received by Australian children from age 4 years to 14 years.Method: Trajectories of mental health symptoms were mapped using the Strengths and Difficulties Questionnaire. Health professional attendances and psychotropic medications dispensed were identified from linked national Medicare Benefits Schedule (MBS) and Pharmaceutical Benefits Scheme records.Results: Four trajectories of mental health symptoms were identified (low, high-decreasing, moderate-increasing and high-increasing). Most children with mental health symptoms had few MBS mental health attendances, and only a minority received care meeting study criteria for minimally adequate treatment. Children in the high-increasing and moderate-increasing trajectories were more likely to access care, yet there was no evidence of improvement in symptoms.Conclusions: It is important that children and adolescents with mental health problems receive treatment that meets minimal practice guidelines. Further research is needed to identify the quality of care currently provided to children with mental health difficulties and how clinicians can be best funded and supported to provide care meeting minimal practice guidelines.Declaration Of Interests: None.

Objective: Adherence to attention-deficit/hyperactivity disorder (ADHD) medication treatment is often suboptimal. This can compromise patient outcomes. We aimed to describe the patterns of ADHD medication use in Australian children, and characteristics associated with patterns of use.Design: Dispensing data were analysed for all redeemed prescriptions of methylphenidate, dexamphetamine and atomoxetine between May 2002 and March 2015 from waves 1 to 6 of the Longitudinal Study of Australian Children (n=4634, age 4-5 years at wave 1). Medication coverage was defined as the proportion of time between the first and the last redeemed prescriptions in which the child was taking medication. Associations between predictor variables (child sex, ADHD symptom severity, age at first prescription, family socioeconomic status (SES), single parent status, parent education and parent mental health) and medication coverage were examined using regression analyses.Results: 166 (3.6%) children had ever redeemed a prescription for an ADHD medication. Boys had higher odds of having taken ADHD medication than girls (OR=3.9; 95% CI 2.7 to 5.7). The mean medication coverage was 59.8%. Medication coverage was lower in children from families of lower SES (β=4.0; 95% CI 0.2 to 7.8, p=0.04). Medication coverage was relatively high in the first year of prescription, then decreased progressively, only increasing again after 5 or 6 years of treatment.Conclusions: Children with ADHD from socially disadvantaged families were less likely to receive medication consistently. Prescribers need to continue to support families over many years to ensure medication is used consistently for children with ADHD. [ABSTRACT FROM AUTHOR]

Objective: Retrospective, parent‐reported data suggest that 50% of Australian children with mental health disorders miss out on care. In a national sample, we aimed to determine the proportion receiving mental health services and associated characteristics, using prospective, objective data. Method: Prospective analysis of linked Medicare Benefits Scheme (MBS)‐rebated mental health service use in children aged 8–9, 10–11, and 12–13 years, from the Longitudinal Study of Australian Children K cohort (N = 4,983). Analyses were conducted separately for children scoring above the cut points on the Strength and Difficulties Questionnaire (SDQ) emotional and externalising problems subscales. Characteristics were compared using logistic regressions. Results: Nine to 27% of children scoring above SDQ cut points accessed MBS‐rebated mental health services, typically from general practitioners, psychologists and paediatricians. Greater symptom severity, parent perception that child needs help, being a young boy and older were associated with increased service use. Children from more disadvantaged families or families speaking a language other than English were less likely to receive services for internalising problems. Conclusion: In the first prospective, objective analysis, most children do not receive mental health services. [ABSTRACT FROM AUTHOR]

Introduction: Severe behavioural problems (SBPs) are a common contributor to morbidity and reduced quality of life in children with intellectual disability (ID). Current medication treatment for SBP is associated with a high risk of side effects. Innovative and safe interventions are urgently needed. Anecdotal reports and preliminary research suggest that medicinal cannabis may be effective in managing SBP in children with developmental disabilities. In particular, cannabidiol (CBD) may be a plausible and safe alternative to current medications. Families who are in urgent need of solutions are seeking cannabis for their ID children with SBP. However there is no evidence from randomised controlled trials to support the use of CBD for SBP. This pilot study aims to investigate the feasibility of conducting a randomised placebo-controlled trial of CBD to improve SBP in children with ID. Methods and analysis: This is a single-site, double-blind, parallel-group, randomised, placebo-controlled pilot study of 10 participants comparing 98% CBD oil with placebo in reducing SBP in children aged 8–16 years with ID. Eligible participants will be randomised 1:1 to receive either CBD 20mg/kg/dayor placebo for 8 weeks. Data will be collected regarding the feasibility and acceptability of all study components, including recruitment, drop-out rate, study visit attendance, protocol adherence and the time burden of parent questionnaires. Safety outcomes and adverse events will be recorded. All data will be reported using descriptive statistics. These data will inform the design of a full scale randomised controlled trial to evaluate the efficacy of CBD in this patient group. Ethics and dissemination: This protocol has receivedethics approval from the Royal Children’s Hospital ethics committee (Human Research Ethics Committee no. 38236). Results will be disseminated through peer-reviewed journals,professional networks, conferences and social media. [ABSTRACT FROM AUTHOR]

This study prospectively examined the role of maternal stress in boys' attention deficit hyperactivity disorder (ADHD) symptoms and quality of life (QoL). Children with ADHD (5–13 years) were recruited from 21 pediatric practices and followed up 12 months later (n = 166). Maternal stress was examined at baseline, and boys' ADHD symptoms and QoL were examined at baseline and 12 months later. Linear regressions examined whether baseline maternal stress predicted child ADHD symptoms and QoL 12 months later in a series of adjusted models that accounted for child age, ADHD medication use, neighborhood disadvantage, comorbidities and baseline ADHD symptoms or QoL (full model). In the unadjusted model, maternal stress at baseline was significantly associated with more severe parent-reported ADHD symptoms at 12 months, accounting for 5.7% of the variance in ADHD symptoms, but this association was attenuated after adjustments in the full model. Baseline maternal stress was associated with poorer QoL at 12 months in boys in the unadjusted model, accounting for 12.4% of the variance, which remained significant in the full adjusted model. Maternal stress is associated with lowered QoL in boys, and may pose a risk for boys' later QoL. Stress management interventions with mothers of children with ADHD experiencing heightened stress are warranted, and are likely to have a positive impact on mothers as well as children. • Maternal stress and boys' 12-month ADHD symptoms and QoL was examined prospectively. • The relationship between stress and boys' symptoms attenuated after accounting for covariates. • Maternal stress predicted boys' later QoL, even after accounting for covariates. • Findings suggest that maternal stress may pose a risk for lowered QoL in boys with ADHD.

Background: We have demonstrated the efficacy of a brief behavioral intervention for sleep in children with ADHD in a previous randomized controlled trial and now aim to examine whether this intervention is effective and cost‐effective when delivered by pediatricians or psychologists in community settings. Methods: Translational, cluster‐randomized trial of a behavioral intervention versus usual care from 19th January, 2015 to 30th June, 2017. Participants (n = 361) were children aged 5–13 years with ADHD and parent report of a moderate/severe sleep problem who met criteria for American Academy of Sleep Medicine criteria for chronic insomnia disorder, delayed sleep–wake phase disorder, or were experiencing sleep‐related anxiety. Participants were randomized at the level of the pediatrician (n = 61) to intervention (n = 183) or usual care (n = 178). Families in the intervention group received two consultations with a pediatrician or a psychologist covering sleep hygiene and tailored behavioral strategies. Results: In an intention‐to‐treat analysis, at 3 and 6 months respectively, the proportion of children with moderate to severe sleep problems was lower in the intervention (28.0%, 35.8%) compared with usual care group (55.4%, 60.1%; 3 month: risk ratio (RR): 0.51, 95% CI 0.37, 0.70, p < .001; 6 month: RR: 0.58; 95% CI 0.45, 0.76, p < .001). Intervention children had improvements across multiple Children's Sleep Habits Questionnaire subscales at 3 and 6 months. No benefits of the intervention were observed in other domains. Cost‐effectiveness of the intervention was AUD 13 per percentage point reduction in child sleep problem at 3 months. Conclusions: A low‐cost brief behavioral sleep intervention is effective in improving sleep problems when delivered by community clinicians. Greater sample comorbidity, lower intervention dose or insufficient clinician supervisions may have contributed to the lack benefits seen in our previous trial. [ABSTRACT FROM AUTHOR]

Objective: To describe the relationship between ADHD symptom severity and quality of life (QoL) across three time points over a 12-month period and investigate whether sleep modifies this relationship.Method: Children aged 5 to 13 years with ADHD were recruited from 21 pediatric practices across Victoria, Australia ( N = 392). Child QoL (parent-report) and ADHD symptoms (both parent- and teacher-report) were assessed at three time points (0, 6, and 12 months), and sleep was assessed at baseline (parent-report). Data were analyzed using Pearson's correlations and autoregressive cross-lagged panel models.Results: Parent-reported ADHD symptoms predicted poorer QoL at each subsequent time point ( r = -.10 to -.13), and a small bidirectional relationship was observed between teacher-reported ADHD symptoms and QoL from 6 to 12 months. Sleep moderated the relationship between ADHD symptoms and QoL.Conclusion: Clinicians need to look beyond core ADHD symptoms to other factors that may be influencing QoL in children with ADHD.

Exposure to maternal mental health problems during pregnancy and the first year of life has been associated with the development of ADHD. One pathway through which maternal mental health may influence children's outcomes is via its effects on parenting. This study aimed to investigate the mediating role of parenting behavior in the pathway between maternal postnatal distress and later symptoms of ADHD in the child. Biological mothers living with their children participating in the Longitudinal Study of Australian Children with data available from waves 1 (child age 3–12 months) and 5 (child age 8–9 years) were included in the current study (n = 3456). Postnatal distress was assessed by parent report at wave 1. Parenting warmth, hostility and consistency were assessed by parent report at wave 5. ADHD status at wave 5 was ascertained by parent report of the child having a diagnosis of ADHD/ADD or by elevated ADHD symptoms by both parent and teacher report. There was evidence of an indirect pathway from maternal postnatal distress to child ADHD at age 8–9 years via parenting hostility, but not through parenting warmth or consistency, even after accounting for concurrent maternal mental health. Our findings highlight the importance of early identification and intervention for maternal postnatal distress, as treatment may prevent mothers from developing hostile parenting practices and also disrupt the pathway to ADHD in their offspring.

Background: Sleep problems and daytime sleepiness are common in children with attention-deficit hyperactivity disorder (ADHD) and are associated with poor parent-reported functional outcomes. However, the potential impact of sleep problems or daytime sleepiness on the school functioning of children with ADHD remains unknown. We aimed to determine if sleep problems and daytime sleepiness were associated with the social, emotional, and behavioral school-based functioning of children with ADHD and comorbid sleep problems. Methods: Children aged 5–13 years with ADHD and a moderate-severe sleep problem (confirmed using American Academy of Sleep Medicine diagnostic criteria) were recruited from 43 pediatric practices across Victoria and Queensland, Australia (N = 257). Parent-rated sleep problems were assessed using the Children's Sleep Habits Questionnaire (CSHQ) and teacher-rated daytime sleepiness using the Teacher's Daytime Sleepiness Questionnaire. Teacher-rated social, emotional, and behavioral school functioning was assessed using three scales (peer problems, emotional problems, and conduct problems) from the Strength and Difficulties Questionnaire. Data was analyzed using Pearson correlations and linear regression models. Results: Teacher-rated daytime sleepiness was associated with higher levels of emotional (β = 0.39; 95% CI = 0.25–0.52) and behavioral problems (β = 0.47; CI = 0.36–0.58) in adjusted models. While total sleep duration and parent-rated sleep problems were not associated with daytime sleepiness or school functioning, the CSHQ subscale night wakings was correlated with teacher-rated daytime sleepiness (r = 0.21; p < 0.01). Conclusions: Daytime sleepiness (possibly as an indicator of sleep quality) may be a better predictor of school functioning in children with ADHD who have concomitant sleep problems than total sleep duration or parent-rated sleep problems.
