Titre : The impact of experimental sleep restriction on affective functioning in social and nonsocial contexts among adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Dana L. MCMAKIN, Auteur ; Ronald E. DAHL, Auteur ; Daniel J. BUYSSE, Auteur ; Jennifer C. COUSINS, Auteur ; Erika E. FORBES, Auteur ; Jennifer S. SILK, Auteur ; Greg J. SIEGLE, Auteur ; Peter L. FRANZEN, Auteur Article en page(s) : p.1027-1037 Langues : Anglais (eng) Mots-clés : Sleep sleep restriction adolescence affect emotion emotional reactivity emotion regulation pupillography social behavior Index. décimale : PER Périodiques Résumé : Background Short sleep duration is highly prevalent in adolescence, and it prospectively predicts problems with emotional adjustment and psychiatric health. To move beyond epidemiological associations and inform models of developmental psychopathology, we experimentally restricted sleep to observe impacts on affective functioning. Based on the importance of social contexts to adolescent emotional experiences, we also examined the impact of restricted sleep on socioaffective functioning in an ecologically valid peer interaction task. Methods In Study 1, adolescents (ages 11.5–15.0, n = 48) were randomly assigned to two nights of polysomnography-monitored sleep restriction (4 hr in bed) or extension (10 hr in bed). One week later, they completed the other sleep manipulation. Affective functioning was assessed by self-report and pupil response to standardized affective sounds. Study 2 used a similar protocol and invited adolescents (ages 12–15.0, n = 16) to the sleep laboratory along with 2–4 friends to observe affective behavior in a social context primed for peer conflict. Mixed effects models were used to evaluate the effect of sleep condition on affective outcomes. Results Study 1 demonstrated increased negative affect following sleep restriction, relative to extension, on self-report (p = .02) and pupil measures (p = .01). Study 2 replicated these effects (both p = .04) and demonstrated greater negative affective behavior in a peer social context (p = .01). Exploratory analyses for positive affect showed reductions as assessed by self-report (p = .005), but not pupil (p = .81), in Study 1; and no significant effects in Study 2 (self-report, p = .14; pupil, p = .29; positive affective behavior, p = .43). Conclusions Experimental sleep restriction in adolescence impacts negative affective functioning as evidenced by self-report and pupil reactivity, as well as observed behavior in a social context primed for peer conflict. Implications for the impact of short sleep on developmental trajectories of emotional adjustment and psychiatric health, and opportunities for early intervention, are briefly discussed.

Titre : What time do you plan to sleep tonight? An intense longitudinal study of adolescent daily sleep self-regulation via planning and its associations with sleep opportunity Type de document : Texte imprimé et/ou numérique Auteurs : Svetlana MASKEVICH, Auteur ; Lin SHEN, Auteur ; Sean P. A. DRUMMOND, Auteur ; Bei BEI, Auteur Article en page(s) : p.900-911 Langues : Anglais (eng) Mots-clés : Actigraphy Adolescent Female Humans Longitudinal Studies Male Schools Self-Control Sleep/physiology Adolescents planning sleep restriction sleep self-regulation teenagers unconstrained sleep Index. décimale : PER Périodiques Résumé : BACKGROUND: Most adolescents are sleep deprived on school days, yet how they self-regulate their sleep-wake behaviours is poorly understood. Using ecological momentary assessment, this intense longitudinal study explored patterns of adolescents' daily bedtime and risetime planning and execution, and whether these behaviours predicted sleep opportunity. METHODS: Every afternoon, for 2 school weeks and the subsequent 2 vacation weeks, 205 (54.1% female, 64.4% non-White) adolescents from year 10 to 12 (MÂ+SD(age) =16.9Â+0.9) reported their plans for bedtime (BT) that evening, and for risetimes (RT) the following day. Actual daily sleep was measured via actigraphy and sleep diary. RESULTS: Some adolescents never planned bedtime (school 19.5%, non-school 53.2%) or risetime (school 1.5%, non-school 24.4%). More adolescents planned consistently (â¥75% of days) on school (BT=29.9%, RT=61.3%) compared to non-school nights (BT=3.5%, RT=2.5%). On average, adolescents went to bed later than planned, with longer delays on non-school (71min) compared to school nights (46min). Of those who executed their plans within 15min, more did it consistently (â¥75% of days) on school (BT=40.9%, RT=67.7%) than on non-school nights/days (BT=29.7%, RT=58.6%). Mixed effects models utilizing daily data, controlling for sex, race, and study day, showed that bedtime planning predicted longer time in bed (TIB; p<.01) on school and shorter TIB on non-school nights (p<.01); and greater delay in actual (compared to planned) BT predicted shorter TIB (p<.001). CONCLUSIONS: Adolescents may require support during the transition from parent-controlled to autonomous sleep self-regulation. Bedtime planning on school nights and going to bed as planned are two modifiable sleep regulatory behaviours that are protective and potential therapeutic targets for increasing sleep opportunity in adolescents.
