Sleep restriction alters children's positive emotional responses, but effects are moderated by anxiety / Candice A. ALFANO in Journal of Child Psychology and Psychiatry, 61-10 (October 2020)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 61-10 (October 2020) . - p.1150-1159 Titre : Sleep restriction alters children's positive emotional responses, but effects are moderated by anxiety Type de document : Texte imprimé et/ou numérique Auteurs : Candice A. ALFANO, Auteur ; Joanne L. BOWER, Auteur ; Allison G. HARVEY, Auteur ; Deborah C. BEIDEL, Auteur ; Carla SHARP, Auteur ; Cara A. PALMER, Auteur Article en page(s) : p.1150-1159 Langues : Anglais (eng) Mots-clés : Sleep  anxiety  emotion  emotional expression  emotional regulation Index. décimale : PER Périodiques Résumé : BACKGROUND: An abundance of cross-sectional research links inadequate sleep with poor emotional health, but experimental studies in children are rare. Further, the impact of sleep loss is not uniform across individuals and pre-existing anxiety might potentiate the effects of poor sleep on children's emotional functioning. METHODS: A sample of 53 children (7-11 years, M = 9.0; 56% female) completed multimodal, assessments in the laboratory when rested and after two nights of sleep restriction (7 and 6 hr in bed, respectively). Sleep was monitored with polysomnography and actigraphy. Subjective reports of affect and arousal, psychophysiological reactivity and regulation, and objective emotional expression were examined during two emotional processing tasks, including one where children were asked to suppress their emotional responses. RESULTS: After sleep restriction, deleterious alterations were observed in children's affect, emotional arousal, facial expressions, and emotion regulation. These effects were primarily detected in response to positive emotional stimuli. The presence of anxiety symptoms moderated most alterations in emotional processing observed after sleep restriction. CONCLUSIONS: Results suggest inadequate sleep preferentially impacts positive compared to negative emotion in prepubertal children and that pre-existing anxiety symptoms amplify these effects. Implications for children's everyday socioemotional lives and long-term affective risk are highlighted.

A transdiagnostic sleep and circadian intervention for adolescents: six-month follow-up of a randomized controlled trial / Lu DONG in Journal of Child Psychology and Psychiatry, 61-6 (June 2020)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 61-6 (June 2020) . - p.653-661 Titre : A transdiagnostic sleep and circadian intervention for adolescents: six-month follow-up of a randomized controlled trial Type de document : Texte imprimé et/ou numérique Auteurs : Lu DONG, Auteur ; Michael R.

METHODS: Adolescents (mean [SD] = 14.77 [1.84] years) with eveningness chronotype and "at-risk" in at least one of five health domains were randomized to receive TranS-C (n = 89) or PE (n = 87) at a university-based clinic. Primary outcomes were average weeknight total sleep time and bedtime calculated from sleep diary, a questionnaire measure of circadian preference, and composite risks in five health domains. Secondary outcomes were selected sleep diary indices, sleepiness, and self- and parent-reported sleep, parent-reported risks in five health domains. RESULTS: Relative to PE, TranS-C showed treatment effects through 6-month follow-up on only one primary outcome; namely eveningness circadian preference. TranS-C also showed treatment effects on two sleep and circadian secondary outcomes, including the Pittsburgh Sleep Quality Index and sleep-diary measured weeknight-weekend discrepancy in wakeup time. TranS-C did not show treatment effects on self-report or parent-report composite risks in five health domains. PE showed benefit, relative to TranS-C, from posttreatment to 6-month follow-up for reducing parent-reported behavioral health risk (secondary outcome). CONCLUSIONS: In at-risk adolescents, the evidence supports the TranS-C treatment effects over six months on improving sleep and circadian functioning on selected outcomes but not on reducing risk in five health domains.
