Micro-sequences of anger and shame and non-suicidal self-injury in youth: an ecological momentary assessment study / Leslie A. BRICK ; Michael ARMEY ; Nicole R. NUGENT in Journal of Child Psychology and Psychiatry, 65-2 (February 2024)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 65-2 (February 2024) . - p.137-147 Titre : Micro-sequences of anger and shame and non-suicidal self-injury in youth: an ecological momentary assessment study Type de document : Texte imprimé et/ou numérique Auteurs : Leslie A. BRICK, Auteur ; Michael ARMEY, Auteur ; Nicole R. NUGENT, Auteur Article en page(s) : p.137-147 Index. décimale : PER Périodiques Résumé : Objective Non-suicidal self-injury (NSSI) is a significant mental health concern with the highest prevalence among adolescents. NSSI has been conceptualized as one of the maladaptive strategies to cope with challenging affect or a form of self-punishment. Although characterizing moment-to-moment associations between shame and NSSI in individuals' real-world environment and partitioning between- and within-person effects is critical for mobile and timely interventions, most studies examined habitual experiences of negative affective states and focused on adults. Method In this study, we focused on in vivo anger at self and others and shame and NSSI among 158 adolescents 3?weeks following their psychiatric hospitalizations using ecological momentary assessment (EMA) technology. Results We found that greater between-person levels of anger at self and others were linked to a higher number of subsequent NSSI occurrences within a day. These findings remained primarily unchanged when we statistically adjusted for participants' age, sex assigned at birth, the number of current psychiatric diagnoses, EMA response rates, and youth lifetime history of SI. Within-person increases in NSSI were linked to increased anger at self over and beyond between-person average levels of NSSI. Conclusions These findings highlight the potential regulatory role of NSSI to decrease negative affective states and point to the clinical utility of assessing and early mobile interventions targeting challenging affect in youth.

Single nucleotide polymorphism heritability and differential patterns of genetic overlap between inattention and four neurocognitive factors in youth / Lauren MICALIZZI in Development and Psychopathology, 33-1 (February 2021)  

Public ISBD [article]  inDevelopment and Psychopathology > 33-1 (February 2021) . - p.76-86 Titre : Single nucleotide polymorphism heritability and differential patterns of genetic overlap between inattention and four neurocognitive factors in youth Type de document : Texte imprimé et/ou numérique Auteurs : Lauren MICALIZZI, Auteur ; Leslie A. BRICK, Auteur ; Marisa E. MARRACCINI, Auteur ; Chelsie E. BENCA-BACHMAN, Auteur ; Rohan H. C. PALMER, Auteur ; Valerie S. KNOPIK, Auteur Article en page(s) : p.76-86 Langues : Anglais (eng) Mots-clés : Gcta  adolescence  genetics  heritability  inattention  neurocognitive functioning Index. décimale : PER Périodiques Résumé : Theoretical models of attention-deficit/hyperactivity disorder implicate neurocognitive dysfunction, yet neurocognitive functioning covers a range of abilities that may not all be linked with inattention. This study (a) investigated the single nucleotide polymorphism (SNP) heritability (h2SNP) of inattention and aspects of neurocognitive efficiency (memory, social cognition, executive function, and complex cognition) based on additive genome-wide effects; (b) examined if there were shared genetic effects among inattention and each aspect of neurocognitive efficiency; and (c) conducted an exploratory genome-wide association study to identify genetic regions associated with inattention. The sample included 3,563 participants of the Philadelphia Neurodevelopmental Cohort, a general population sample aged 8-21 years who completed the Penn Neurocognitive Battery. Data on inattention was obtained with the Kiddie Schedule of Affective Disorders (adapted). Genomic relatedness matrix restricted maximum likelihood was implemented in genome-wide complex trait analysis. Analyses revealed significant h2SNP for inattention (20%, SE = 0.08), social cognition (13%, SE = 0.08), memory (17%, SE = 0.08), executive function (25%, SE = 0.08), and complex cognition (24%, SE = 0.08). There was a positive genetic correlation (0.67, SE = 0.37) and a negative residual covariance (-0.23, SE = 0.06) between inattention and social cognition. No SNPs reached genome-wide significance for inattention. Results suggest specificity in genetic overlap among inattention and different aspects of neurocognitive efficiency.
