Against the use of the Strengths and Difficulties Questionnaire for Aboriginal and Torres Strait Islander children aged 2-15 years.

OBJECTIVE: The Strengths and Difficulties Questionnaire is a widely used screening tool for emotional and behavioural problems in children. Recent quantitative analyses have raised concerns regarding its structural validity in Aboriginal and Torres Strait Islander communities. This paper aims to extend upon existing findings by analysing the factor structure of both the parent- and teacher-reported Strengths and Difficulties Questionnaire in this population across a broader age range than in previous studies. METHODS: Participants were the caregivers and teachers of 1624 Aboriginal and Torres Strait Islander children (820 male, 804 female) aged 2-15 years from Waves 2-11 of the Longitudinal Study of Indigenous Children. The majority of children were Aboriginal living in major cities and inner regional areas. Internal consistency was estimated with McDonald's Omega. Exploratory structural equation modelling was conducted to investigate the factor structure of the parent-reported and teacher-reported versions of the Strengths and Difficulties Questionnaire. RESULTS: Responses from teachers demonstrated higher internal consistency than responses from parents, which was unacceptably low across most age groups. The purported five-factor structure of the Strengths and Difficulties Questionnaire failed to be replicated across both parent- and teacher-reported questionnaires. The results of bifactor and hierarchical exploratory structural equation models also failed to approximate the higher-order summary scales. These results indicate that the Strengths and Difficulties Questionnaire subscales and summary scores do not provide a valid index of emotional and behavioural problems in Aboriginal and Torres Strait Islander children. CONCLUSION: The Strengths and Difficulties Questionnaire should not be used with Aboriginal and Torres Strait Islander children.

Dysfunctional sleep beliefs and behaviours: Psychological factors in sleep-related headaches.

Sleep problems are amongst the most common triggers of migraine and non-migraine primary headache. Despite a majority of sleep problems being psychological in nature, there is a paucity of quantitative research on the psychological factors involved in sleep-related headaches. This is the first study to examine the link between maladaptive sleep beliefs and headaches. 542 participants completed an online battery measuring headache, sleep, and psychological distress. Avoidance of sleep-related headache triggers was associated with more headaches, as mediated by increased sensitivity to the triggers. Sleep quality, sleep beliefs, and sleep behaviours all significantly (p < .001) correlated with headache frequency and disability, with effect sizes ranging from small (rs = 0.16) to medium (rs = 0.37). Mediation models testing the effect of sleep beliefs on headaches via sleep quality (covaried by sleep behaviours) accounted for 13% and 14% of variance in migraine and non-migraine headaches, respectively (p < .001). Avoidance of sleep-related headache triggers was shown to be associated with greater headache frequency (via increased trigger sensitivity). It is posited that maladaptive sleep beliefs and behaviours may increase headache activity by causing poor sleep quality, leading to dysregulation in brain regions shared between sleep and headaches.

Examining the pharmacological and psychological treatment of child and adolescent ADHD in Australia: Protocol for a retrospective cohort study using linked national registry data.

INTRODUCTION: Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder which affects 5% of children globally. In Australia, it is estimated that 4.1% of children and adolescents have ADHD. While research has examined the treatment and outcomes of children with ADHD attending public mental health services during their time in the public system in Australia, it is not known what treatment they received before and after these treatment episodes, which will provide a more complete understanding of these children's treatment journey. METHODS AND ANALYSIS: We will link clinical data from cohorts of children and adolescents treated in the public child and youth mental health and/or child development services in Brisbane, Melbourne and Sydney to the Medicare Benefits Schedule (MBS), Pharmaceutical Benefits Scheme (PBS) and National Death Index. MBS data will demonstrate the treatment journey with respect to clinicians seen, and treatment episodes from the public health service data sets will be examined to assess if the type and intensity of treatment are related to treatment outcomes. PBS data will reveal all psychotropic medications prescribed, allowing an examination of not just ADHD medications, but also other psychotropics which may indicate co-occurring conditions (eg, anxiety and mood disorders). Statistical analyses will include descriptive statistics to describe the rates of specific medications and clinician specialties seen. Linear and logistic regression will be used to model how treatment and sociodemographic variables relate to routinely collected outcome measures in the public health system while controlling for covarying factors. ETHICS AND DISSEMINATION: This study has been approved by the following institutional ethics committees: (1) Children's Health Queensland Hospital and Health Service (HREC/21/QCHQ/76260), (2) The University of Queensland (2021/HE002143) and (3) The Australian Institute of Health and Welfare (EO2021/4/1300). Findings will be disseminated through peer-reviewed journals, conferences, professional associations and to public mental health services that treat ADHD.

Psychological Sleep Interventions for Migraine and Tension-Type Headache: A Systematic Review and Meta-Analysis.

Disordered sleep, poor sleep quality, and insufficient or excessive sleep duration are known triggers of primary and secondary headaches. Given this, it is plausible that improving sleep will subsequently reduce headache activity. We report a systematic review of the literature, examining studies utilising psychological sleep interventions for the treatment of migraine and tension-type headache. PubMed, EMBASE, CINAHL, PsycINFO, and Cochrane Central were searched, using terms pertaining to psychological sleep interventions and headaches. Meta-analysis was performed for two outcome measures; headache frequency, and headache intensity. 103 studies were retrieved, of which 55 were duplicates. After completing reviews, three studies were retained. An additional eligible study was published after the initial search, and was found via monthly update searches, resulting in a total of four included studies. The effects of psychological sleep interventions (and in one study, combined with drug therapy) significantly reduced headache frequency and headache intensity. Three studies improved various sleep outcomes such as duration, efficiency, and excessive sleepiness. Psychological sleep interventions improve headache frequency and sleep, however there is conflicting evidence for the effect on headache intensity between studies. Limitations include the small number of studies conducted to date. Despite this, the notable improvements in headaches and sleep achieved after psychological sleep interventions indicates further research on this promising topic is warranted.
