Altered threat-related information processing has been put forward as a potential process underlying the association between childhood adversity and psychiatric disorders, with previous research providing support for decreased discrimination between threat and safety cues, in both children and adults exposed to adversity. This altered threat-safety discrimination has been hypothesized to stem from increased generalization of fear, yet to date, this hypothesis has not been tested in youth. Methods Here, we investigate whether childhood adversity is associated with fear generalization during adolescence. 119 adolescents between 12 and 16 years of age (mean 13.95), of whom 63 exposed to childhood adversity, completed a fear generalization paradigm. Fear conditioning was assessed through trial-by-trial US expectancy ratings and post-experimental ratings of fear, valence and arousal. Additionally, we administered a perceptual discrimination task to assess the potential impact of perceptual discrimination abilities upon fear generalization. Results In line with our hypotheses, results showed that childhood adversity is associated with (1) reduced threat-safety differentiation during fear acquisition and (2) increased fear generalization in both boys and girls, albeit to a different extent, as boys showed more generalization towards safety cues while girls showed more generalization towards dangerous cues. Moreover, this overgeneralization of fear could not be attributed to group differences in perceptual discrimination. Conclusions Altered fear learning may be an important process through which adversity increases risk for the development of psychopathology. Longitudinal research is essential to elucidate risk and resilience patterns following childhood adversity.

Unraveling psychosis risk in sexual minorities: temporal dynamics of social defeat and suspiciousness in adolescence / Margaux SAGEOT in Journal of Child Psychology and Psychiatry, 67-2 (February 2026)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 67-2 (February 2026) . - p.296-304 Titre : Unraveling psychosis risk in sexual minorities: temporal dynamics of social defeat and suspiciousness in adolescence Type de document : texte imprimé Auteurs : Margaux SAGEOT, Auteur ; Robin ACHTERHOF, Auteur ; Anu P. HIEKKARANTA, Auteur ; Aleksandra LECEI, Auteur ; Kristof VANSTEELAND, Auteur ; Inez MYIN-GERMEYS, Auteur ; Ruud VAN WINKEL, Auteur Article en page(s) : p.296-304 Langues : Anglais (eng) Mots-clés : Psychotic experiences  sexual minority youth  belonging  ESM  exclusion Index. décimale : PER Périodiques Résumé : Background Previous research suggests that sexual minorities are at higher risk for psychotic experiences, possibly due to repeated social defeat experiences. However, empirical research investigating this hypothesis is largely lacking. This study examined how experiences of ?feeling excluded? and ?not belonging? impact the prospective development of psychotic experiences in an adolescent sexual minority group, defined here as non-heterosexual attraction to others. Methods Experience sampling method (ESM) data from 1913 Flemish adolescents (aged 11?20) in the SIGMA study were analyzed. They reported their momentary feelings of exclusion when alone, belonging when in the company of others (both operationalizations of social defeat), and suspiciousness. Multilevel linear regression models tested the bidirectional, within- and between-person associations between social defeat and suspiciousness, and the effects of sexual minority status. Results Lower feelings of belonging when in company significantly predicted higher suspiciousness at the next beep [95% CI: ?0.03, ?0.01], whereas increased feelings of exclusion when alone did not. Moreover, suspiciousness did not significantly predict feelings of exclusion and belonging at the next beep, confirming the direction of effect. Sexual minority participants reported generally lower belonging in social settings [95% CI: ?0.68, ?0.29] and higher suspiciousness [95% CI: 0.16, 0.57], but not higher feelings of exclusion. The interaction between social defeat and sexual minority status was not significant, indicating no differential sensitivity to social defeat experiences. Conclusions The experience of ?not fitting in? when in company may be the most poignant social factor increasing risk for psychotic experiences in sexual minority youth. The findings highlight the need for inclusive environments where sexual minority individuals feel supported and integrated.
