One hundred and two adults with clinician-diagnosed autism completed structured clinical interview assessments of lifetime histories of suicidal ideation, attempts, and NSSI. Predictors were six Comprehensive Autistic Trait Inventory (CATI) subscales and selected Personality Inventory for DSM-5 Short Form (PID-5-SF) domains and facets. We fit CATI-only, PID-5 domain, and facet models, then combined significant predictors and refit with age, sex, and IQ as covariates. Shared variance between PID-5-SF facet Anhedonia and CATI Social Interactions showed suppression in joint models, and latent variable modeling confirmed that their shared variance?indexing overlapping reward and social disengagement?was the most consistent correlate of risk across outcomes. PID-5-SF facet Emotional Lability was robustly related to NSSI and to ideation severity. CATI Self-Regulatory Behaviors predicted NSSI. PID-5-SF domain Disinhibition showed no associations. Higher IQ showed a modest protective effect for attempts. Findings highlight central roles of reward-related processes and affective volatility, with added contributions from interpersonal strain and self-regulation. Combining CATI with PID-5 yields complementary targets for assessment and intervention. Key strengths include a clinician-diagnosed autistic sample, a rare direct comparison of people with lifetime suicidal ideation vs. suicide attempts, and an integrated trait framework that moves the field beyond prevalence toward trait-informed risk. Findings support brief screening for anhedonia and emotional lability, autism-adapted behavioral activation, rapid arousal-reduction skills, and attention to social communication needs that may impede disclosure and help-seeking.

Neural reward responsiveness in children who engage in nonsuicidal self-injury: an ERP study / Aliona TSYPES in Journal of Child Psychology and Psychiatry, 59-12 (December 2018)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 59-12 (December 2018) . - p.1289-1297 Titre : Neural reward responsiveness in children who engage in nonsuicidal self-injury: an ERP study Type de document : texte imprimé Auteurs : Aliona TSYPES, Auteur ; Max OWENS, Auteur ; Greg HAJCAK, Auteur ; Brandon E. GIBB, Auteur Article en page(s) : p.1289-1297 Langues : Anglais (eng) Mots-clés : Nonsuicidal self-injury  children  event-related potential  feedback negativity  rewards Index. décimale : PER Périodiques Résumé : BACKGROUND: A better understanding of the correlates of nonsuicidal self-injury (NSSI) in children is important for the identification and prevention of future suicide risk. However, although abnormalities in reward responsiveness might constitute one potential transdiagnostic mechanism of risk for NSSI, no studies have examined initial response to reward in children with a history of NSSI. The goal of the present study was to address this important gap in the literature. To objectively assess initial response to reward, we utilized the feedback negativity (FN) event-related potential, a well-established psychophysiological marker of reward responsiveness. METHODS: Participants were 57 children (19 with a history of NSSI and 38 demographically matched controls) between the ages of 7 and 11. Diagnostic interviews were used to assess for current and past DSM-IV mood and anxiety diagnoses and NSSI history. Children also completed a guessing task, during which continuous electroencephalography was recorded. RESULTS: Children with a history of NSSI exhibited significantly more negative DeltaFN (i.e., FN to losses minus FN to gains) than children without NSSI. These findings appeared to be at least partially independent of children's history of psychopathology and current symptoms, suggesting their specificity to NSSI. CONCLUSIONS: These results provide initial evidence for heightened neural initial reward responsiveness to losses versus rewards in children with a history of NSSI. Pending replications and longitudinal studies, the DeltaFN might represent a psychophysiological marker of risk for self-harm.

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.

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.
