However, there has been little longitudinal research exploring these associations in adolescence, especially in low- and middle-income countries (LMICs). To address this, we investigated longitudinal pathways from trauma to risk behaviours and cardiovascular health indices among adolescents in the 2004 Pelotas Birth Cohort, Brazil.METHODSLifetime cumulative trauma was assessed via caregiver reports up to age 11, and combined adolescent/caregiver reports at ages 15 and 18. At age 18, current problematic alcohol use, smoking, illicit drug use and sleep duration were measured via self-report and resting heart rate (HR) and blood pressure (BP) were assessed. We tested for trauma risk behaviour-HR/BP associations using multivariable regression, population attributable fractions and counterfactual mediation.RESULTSOf 4,229 adolescents (51.9% boys), 81.9% were trauma-exposed by age 18. Cumulative trauma up to ages 15 and 18 increased the odds of age 18 alcohol, smoking and drug use (adjusted ORs: 1.25-1.44). Sleep duration was unrelated to childhood trauma. Population attributable fractions indicated that childhood trauma explained ≥28% of age 18 substance use. Unexpectedly, greater trauma exposure was associated with lower resting HR and BP. Substance use partially mediated the effect of trauma on cardiovascular health indices.CONCLUSIONSTrauma is associated with substance use in LMIC adolescents. Prevention and intervention strategies targeting trauma are critical given this significant burden. Our finding that trauma predicts lower HR/BP warrants further exploration given well-established associations between trauma and poorer cardiovascular health in adulthood.","PeriodicalId":187,"journal":{"name":"Journal of Child Psychology and Psychiatry","volume":"55 1","pages":""},"PeriodicalIF":7.6,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143893090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We summarize the measurement implications of each conceptual model and common approaches for assessing early‐life adversity in studies utilizing each of these models. We consider other critical components in the assessment of early‐life adversity and trauma, including retrospective and prospective reporting, objective and subjective measurement, and caregiver and child reporting. Finally, we briefly summarize the existing interview and questionnaire measures that are widely used to assess early‐life adversity and trauma using both cumulative risk and dimensional approaches. This work suggests that there is greater heterogeneity in measures used to assess the dimensional model relative to those used to assess the cumulative risk model, which allows for more flexibility in the assessment of early‐life adversity. In addition, we observed that more detailed measures were available to assess experiences of threat compared to experiences of deprivation. Measures that assess adversity experiences in terms of frequency and severity across multiple dimensions of experience within a single measure are needed to facilitate consistent and reliable assessment of early‐life adversity and trauma, particularly when applying dimensional models.","PeriodicalId":187,"journal":{"name":"Journal of Child Psychology and Psychiatry","volume":"25 1","pages":""},"PeriodicalIF":7.6,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143819000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The roles of parental verbal communication and child characteristics in the transmission and maintenance of social fears.","authors":"Selin Zeytinoglu,Lauren K White,Santiago Morales,Kathryn Degnan,Heather A Henderson,Koraly Pérez-Edgar,Daniel S Pine,Nathan A Fox","doi":"10.1111/jcpp.14169","DOIUrl":"https://doi.org/10.1111/jcpp.14169","url":null,"abstract":"BACKGROUNDAlthough social anxiety runs in families, little is known about how parents and children contribute to the intergenerational transmission of social fears. We examined whether mothers transfer social fear beliefs to their children through verbal communication and how children's behavioral inhibition and social anxiety contribute to this transmission. The associations of children's social fear beliefs with peer avoidance and interpretation bias were also examined.METHODSParticipants (N = 291, 54% female) were followed from toddlerhood to middle childhood. Behavioral inhibition was assessed at ages 2 and 3. At the 10-year assessment, mother-child dyads participated in a conversation task. Mothers received ambiguous information about hypothetical peers and then talked to their children about vignettes involving these peers. Mothers' positive and negative statements were coded. Prior to the conversation, dyads reported their own social fear beliefs. Post-conversation, children rated their social fear beliefs and completed symbolic peer avoidance and social interpretive bias tasks. Children self-reported their social anxiety.RESULTSMothers' positive statements mediated the paths from maternal social fear beliefs and behavioral inhibition to children's post-conversation social fear beliefs. Mothers' negative statements also mediated the link between mothers' fear beliefs and children's post-conversation fear beliefs, but only among children with heightened anxiety. Children's post-conversation social fear beliefs were, in turn, associated with children's peer avoidance and interpretation bias.CONCLUSIONSFindings suggest that maternal verbal communication serves as a mechanism in the relation between parent and child social fear beliefs, and children's fear beliefs, in turn, predict their symbolic peer avoidance and interpretative biases. Children with heightened anxiety were particularly impacted by their mothers' negative statements, whereas behavioral inhibition predicted fewer maternal positive statements. Targeting mothers' social fear beliefs and verbal communication patterns may help prevent the intergenerational transmission of social fear.","PeriodicalId":187,"journal":{"name":"Journal of Child Psychology and Psychiatry","volume":"1 1","pages":""},"PeriodicalIF":7.6,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143822477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
