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]

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.

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]

Abstract: Irritability is ubiquitous in child and adolescent psychopathology. This study aimed to determine if the Affective Reactivity Index (ARI), a measure of irritability, could be used to screen for psychopathology in adolescents. The clinical sample comprised 31 adolescents with a DSM-IV diagnosis. The control sample was 31 gender and age matched adolescents recruited through schools. Both samples completed a test battery that included the Affective Reactivity Index. The clinical participants reported significantly higher levels of irritability than the control sample by both self- and parent-report. Using ROC analysis a cut off value of 4 on the self-report ARI was found to be optimal for indicating psychopathology; with a specificity of 77.4% and a sensitivity of 77.4%, the area under the curve was 0.86. This paper provides evidence to suggest that irritability may be used as a general predictor of psychopathology in adolescents. [Copyright &y& Elsevier]
