Longitudinal associations between violence exposure and adolescent conduct problems in a high-adversity, South African setting / Susan SWINGLER in Journal of Child Psychology and Psychiatry, 67-8 (August 2026)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 67-8 (August 2026) . - p.1244-1253 Titre : Longitudinal associations between violence exposure and adolescent conduct problems in a high-adversity, South African setting Type de document : texte imprimé Auteurs : Susan SWINGLER, Auteur ; Qing HAN, Auteur ; Alexis E.

This study investigated whether early adolescent violence exposure predicts concurrent and longer-term conduct problems, and explored potential bidirectional associations and sex differences in a peri-urban South African community with high rates of poverty and violence. Methods Data were drawn from the Thula Sana birth cohort (n?=?357; 51.5% female), a longitudinal intervention study in Khayelitsha, South Africa. Adolescents were assessed at early (ages 12?14) and late adolescence (ages 16?19). Violence exposure was measured using adolescent self-report. Conduct problems were measured using adolescent and caregiver report in early adolescence and adolescent self-report in late adolescence. Multiple linear regressions tested cross-sectional associations, and cross-lagged panel models examined longitudinal and bidirectional associations, adjusting for contextual adversity and intervention status. Missing data were addressed using multiple imputation, and findings were confirmed through sensitivity analyses. Results Violence exposure was associated with higher concurrent conduct problems in early adolescence (??=?.15?.19, p??.05). Interaction analyses did not provide evidence that associations differed by sex. Conclusions Violence exposure in early adolescence represents a prospective risk factor for conduct problems in a high-adversity South African setting. Findings highlight the importance of early, contextually grounded violence prevention and the need for further research to test sex-specific pathways and inform the development of gender-responsive intervention strategies.

Trajectories of cognitive development during adolescence among youth at-risk for schizophrenia / Hannah DICKSON in Journal of Child Psychology and Psychiatry, 59-11 (November 2018)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 59-11 (November 2018) . - p.1215-1224 Titre : Trajectories of cognitive development during adolescence among youth at-risk for schizophrenia Type de document : texte imprimé Auteurs : Hannah DICKSON, Auteur ; Alexis E. CULLEN, Auteur ; Rebecca JONES, Auteur ; Abraham REICHENBERG, Auteur ; Ruth ROBERTS, Auteur ; Sheilagh HODGINS, Auteur ; Robin G. MORRIS, Auteur ; Kristin R. LAURENS, Auteur Article en page(s) : p.1215-1224 Langues : Anglais (eng) Mots-clés : Psychosis  academic performance  executive function  intelligence  memory Index. décimale : PER Périodiques Résumé : BACKGROUND: Among adults with schizophrenia, evidence suggests that premorbid deficits in different cognitive domains follow distinct developmental courses during childhood and adolescence. The aim of this study was to delineate trajectories of adolescent cognitive functions prospectively among different groups of youth at-risk for schizophrenia, relative to their typically developing (TD) peers. METHOD: Using linear mixed models adjusted for sex, ethnicity, parental occupation and practice effects, cognitive development between ages 9 and 16 years was compared for youth characterised by a triad of well-replicated developmental antecedents of schizophrenia (ASz; N = 32) and youth with a least one affected relative with schizophrenia or schizoaffective disorder (FHx; N = 29), relative to TD youth (N = 45). Participants completed measures of IQ, scholastic achievement, memory and executive function at three time-points, separated by approximately 24-month intervals. RESULTS: Compared to TD youth, both ASz and FHx youth displayed stable developmental deficits in verbal working memory and inhibition/switching executive functions. ASz youth additionally presented with stable deficits in measures of vocabulary (IQ), word reading, numerical operations, and category fluency executive function, and a slower rate of growth (developmental lag) on spelling from 9 to 16 years than TD peers. Conversely, faster rates of growth relative to TD peers (developmental delay) were observed on visual and verbal memory, and on category fluency executive function (ASz youth only) and on matrix reasoning (IQ) and word reading (FHx youth only). CONCLUSIONS: These differential patterns of deviation from normative adolescent cognitive development among at-risk youth imply potential for cognitive rehabilitation targeting of specific cognitive deficits at different developmental phases.
