FRANZEN, Auteur Article en page(s) : p.27-38 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Identifying proximal risk factors for suicidal ideation that are modifiable and relevant for adolescents and young adults is critical for suicide prevention. This study used an intensive monitoring approach to examine whether objectively- and subjectively- measured sleep characteristics predict next-day suicidal ideation occurrence and intensity through affective reactivity to interpersonal events in young people at high risk for suicide. Methods Participants included 59 (13-23 years; 76% White; 75% female) adolescents and young adults undergoing intensive outpatient program treatment for depression and suicidality. Participants completed daily ratings of suicidal ideation, sleep quality, and affective reactivity to positive and negative interpersonal events for up to 3 months (M=56 days, SD=24.13). Actigraphy captured behavioral sleep duration and timing. Multilevel modeling was used to evaluate within-person fluctuations in sleep and affective reactivity as predictors of suicidal ideation, and multilevel mediation tested the indirect effects of sleep on suicidal ideation via affective reactivity to interpersonal events. Results Results indicate significant indirect effects of objectively measured sleep duration and subjective sleep quality on next-day suicidal ideation via affective reactivity to negative and positive interpersonal events, respectively. Shorter-than-usual sleep predicted the presence and intensity of next-day suicidal ideation via heightened affective reactivity to negative interpersonal events. Worse sleep quality than usual predicted next-day suicidal ideation via reduced affective reactivity to positive interpersonal events. Conclusions Affectivity reactivity is a proximal mechanism through which sleep indices may influence risk for suicidal thinking on a daily basis. Findings highlight the utility of targeting sleep and emotion regulation in suicide prevention among adolescents and young adults at high-risk for suicide.

The impact of experimental sleep restriction on affective functioning in social and nonsocial contexts among adolescents / Dana L. MCMAKIN in Journal of Child Psychology and Psychiatry, 57-9 (September 2016)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 57-9 (September 2016) . - p.1027-1037 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.

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.
