Childhood maltreatment, neuropsychological function and suicidal behavior / Jamie ZELAZNY in Journal of Child Psychology and Psychiatry, 60-10 (October 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-10 (October 2019) . - p.1085-1093 Titre : Childhood maltreatment, neuropsychological function and suicidal behavior Type de document : texte imprimé Auteurs : Jamie ZELAZNY, Auteur ; Nadine MELHEM, Auteur ; Giovanna PORTA, Auteur ; Candice BIERNESSER, Auteur ; John G.

BRENT, Auteur Article en page(s) : p.1085-1093 Langues : Anglais (eng) Mots-clés : Maltreatment  depression  executive function  suicidal behavior Index. décimale : PER Périodiques Résumé : BACKGROUND: Suicide is the second leading cause of death in young people. Childhood maltreatment, neuropsychological dysfunction and psychopathology have each been shown to increase risk for suicidal behavior. However, few studies have examined their interactions and the effects of those interactions on suicidal behavior. METHODS: Across two sites, a total of 382 offspring of depressed parents underwent neuropsychological assessments. This high-risk sample included nearly equal numbers of males and females. Average age at the time of neuropsychological assessment was 18.5 years. The most prevalent lifetime psychiatric disorders were mood (43%), anxiety (37%) and alcohol and substance use disorders (21%). Childhood maltreatment was reported by 44% of offspring. Participants underwent extensive neuropsychological testing assessing the following domains: attention, memory, executive function, working memory, language fluency, and impulse control. Logistic regression was used to examine the association of reported childhood maltreatment, neuropsychological functioning, psychopathology and their interactions with suicidal behavior. Bonferroni correction was used to adjust for multiple comparisons. RESULTS: Maltreatment was associated with increased risk of suicidal behavior with odds ratios ranging between 2.40 and 4.43. Moderation analyses found that adaptive neuropsychological functioning was not protective against childhood maltreatment's effect on suicidal risk. While lifetime history of mood disorder was strongly associated with suicidal behavior, higher scores in working memory (OR = 0.21; 95% CI = 0.09, 0.45; p < .001) and executive function (OR = 0.15; 95% CI = 0.05, 0.43; p < .001) were protective against suicidal behavior even in the presence of a lifetime history of mood disorder. CONCLUSIONS: Further research is needed to determine how neuropsychological capacity protects depressed patients against the risk of suicidal behavior.

Sleep influences daily suicidal ideation through affective reactivity to interpersonal events among high-risk adolescents and young adults / Jessica L. HAMILTON in Journal of Child Psychology and Psychiatry, 64-1 (January 2023)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 64-1 (January 2023) . - p.27-38 Titre : Sleep influences daily suicidal ideation through affective reactivity to interpersonal events among high-risk adolescents and young adults Type de document : texte imprimé Auteurs : Jessica L.

GOLDSTEIN, Auteur ; Peter L. 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.
