[Assessments of sleepiness in adolescents: A key tool for better intervene in mental health]. / Évaluer la somnolence diurne auprès des adolescents : un incontournable pour mieux intervenir en santé mentale.

Objectives Daytime sleepiness in adolescents has negative impacts on physical, cognitive, and emotional health, with direct or indirect consequences on their mental health. This review aims to describe specialized tools assessing daytime sleepiness in adolescents so that mental health professionals can screen for a variety of sleep disorders, from the rarest ones, such as narcolepsy, to the most common ones, such as sleep-wake cycle delay in adolescents. Method Articles were selected in Medline (https://pubmed.ncbi.nlm.nih.gov/) and targeted adolescents aged between 13 and 18 or the keyword "adolescent*". The keywords used were: "sleepiness test" AND "questionnaire*". Only articles in French or English and published until January 9, 2023 were included. A total of 277 scientific articles were screened. Final sample included a total of 35 articles describing sleepiness measurement tools in adolescents. Results Among the 35 articles, a total of seven daytime sleepiness measurement tools in adolescents were identified. Four of them were subjective: 1) the Epworth Sleepiness Scale for Children and Adolescents (ESS-CHAD), 2) the Pediatric Daytime Sleepiness Scale (PDSS), 3) the Cleveland Adolescent Sleepiness Questionnaire (CASQ) and 4) the French Sleepiness Scale for Adolescents (FSSA). These self-reported questionnaires are less expensive and they can be used easily by mental health professionals as opposed to objective tools. Three objective tools have been identified: 1) the multiple sleep latency test (MSLT), 2) the maintenance of wakefulness test or called the "Maintenance Wakefulness Test" (MWT) and 3) the pupillographic sleepiness test (PST). Conclusion Given that adolescents end-of the-day sleep pressure, often resulting in a greater opportunity to light exposure, they are more at risk for daytime sleepiness and consequently to mental health challenges. Mental health professionals should therefore systematically screen for daytime sleepiness in adolescents using subjective tools. There are reliable and validated tools that are translated into French, such as the FSSA and the ESS-CHAD to measure daytime sleepiness in adolescents and lifestyles problems associated with sleep loss When daytime sleepiness suggests the presence of medical-based sleep disorders, such as narcolepsy, restless sleep disorders or sleep apnea, it is important to pursue an investigation with objective tools (nocturnal polysomnography, MLST and MWT) in collaboration with the adolescent's physician.

Sleep ecology, objective sleep characteristics and behavior problems in preschoolers referred to child protection services: An exploratory study.

BACKGROUND: Exposure to environmental risk factors increases the negative impact maltreatment has on children's development. Sleep ecology (i.e., sleep hygiene and home sleeping conditions) can be one of these factors. Poor sleep hygiene and suboptimal home sleeping conditions can alter sleep characteristics, which in turn, may lead to behavior problems (BPs), highly prevalent in maltreated preschoolers. OBJECTIVES: Describe sleep ecology in maltreated preschoolers and explore associations between their sleep ecology, objective sleep characteristics and BPs. METHOD: Parents (n = 22) completed the Children's Sleep Hygiene Scale (CSHS), and a sleep environment questionnaire to document sleep ecology. Children wore an actigraph to record objective sleep characteristics. Parents completed the Behavioral Assessment Scale for Children (BASC-2) to assess children's BPs. Descriptive and correlational analyses were performed. RESULTS: Most of the parents (90.5 %) reported adequate sleep hygiene. However, 20 parents (95.2 %) reported suboptimal home sleeping conditions. Better physiological and overall sleep hygiene were related to earlier sleep onset. Better emotional sleep hygiene was associated with shorter nighttime awakenings and better sleep efficiency. Later sleep onset was associated with lower anxiety, and longer 24-hour sleep duration with higher somatization. Better physiological sleep hygiene was associated with less depression, and better emotional sleep hygiene with less hyperactivity. CONCLUSION: This study showed that sleep hygiene could be associated with maltreated preschoolers' sleep characteristics and BPs, and that their home sleeping conditions may be of concern. Associations between sleep ecology, objective sleep characteristics and BPs deserve to be better understood, and further explored.

Sleep ecology, sleep characteristics and behavior problems in young maltreated children: A scoping review.

BACKGROUND: Behavior problems are highly prevalent in young maltreated children. Their etiology is multifactorial and has been widely documented. Lately, researchers paid increased attention to the role of sleep in non-maltreated children's behavior problems. They showed that poor sleep (e.g., short sleep duration, nocturnal awakenings) increased behavior problems. In addition, an inadequate sleep ecology (e.g., lack of sleep hygiene or bedtime routine) may lead to sleep problems. OBJECTIVE: As maltreated children often live in disorganized environments, this study aims to map knowledge about sleep ecology and sleep characteristics, as well as their associations with behavior problems in young maltreated children from one to five years old. METHOD: A scoping review was performed according to the PRISMA-SR checklist. Bibliographic databases were searched from 1993 to May 2020. RESULTS: From the 650 studies screened, nine reported results about sleep ecology or sleep characteristics or their associations with behavior problems in young maltreated children. Only one study described their sleep ecology. Eight studies documented or compared sleep characteristics, showing slight differences between maltreated and non-maltreated children (e.g., longer nighttime sleep duration or shorter naps in maltreated children). Four studies revealed associations between sleep characteristics and behavior problems in young maltreated children (e.g., shorter sleep duration was associated with more externalizing behaviors). CONCLUSION: Literature about sleep ecology, sleep characteristics, as well as with their associations with behavior problems in young maltreated children is scarce. Their sleep ecology especially deserves to be investigated. Longitudinal studies, studies with comparison groups, combining objective and subjective validated sleep measures, and taking into account maltreatment characteristics and children's developmental stage should be pursued.
