Air Pollution Exposures and Child Executive Function: A U.S. Multi-Cohort Study.

BACKGROUND: Executive function, which develops rapidly in childhood, enables problem solving, focused attention, and planning. Animal models describe executive function decrements associated with ambient air pollution exposure, but epidemiologic studies are limited. METHODS: We examined associations between early childhood air pollution exposure and school-aged executive function in 1,235 children from three U.S. pregnancy cohorts in the ECHO-PATHWAYS Consortium. We derived point-based residential exposures to ambient particulate matter ≤2.5µm in aerodynamic diameter (PM2.5) and nitrogen dioxide (NO2), and ozone (O3) at ages 0-4 years from spatiotemporal models with a 2-week resolution. We assessed executive function across three domains -- cognitive flexibility, working memory, and inhibitory control -- using performance-based measures and calculated a composite score quantifying overall performance. We fitted linear regressions to assess air pollution - child executive function associations, adjusting for sociodemographic characteristics, maternal mental health, and health behaviors, and examined modification by child sex, maternal education, and neighborhood educational opportunity. RESULTS: In the overall sample, we found hypothesized inverse associations in crude but not adjusted models. Modified associations between NO2 exposure and working memory by neighborhood education opportunity were present (P interaction = 0.05), with inverse associations more pronounced in the "High" and "Very high" categories. Associations of interest did not differ by child sex or maternal education. CONCLUSIONS: This work contributes to the evolving science regarding early-life environmental exposures and child development. There remains a need for continued exploration in future research endeavors, to elucidate the complex interplay between natural environment and social determinants influencing child neurodevelopment.

Associations between middle childhood executive control aspects and adolescent substance use and externalizing and internalizing problems.

This study examines the degree to which two middle childhood executive control aspects, working memory and combined inhibitory control/flexible shifting, predict adolescent substance use and externalizing and internalizing problems. Participants were 301 children (ages 3-6 years; 48.2% male) recruited from a Midwestern city in the United States and followed into adolescence (ages 14-18 years). Working memory had a statistically significant unadjusted association with externalizing problems (r = -.30, p = .003) in a confirmatory factor analysis. Neither factor significantly predicted any of the adolescent outcomes in a structural equation model that adjusted for each EC aspect, sociodemographic covariates, and middle childhood externalizing and internalizing problems. Stronger prediction of EC aspects might not emerge until they become more fully differentiated later in development.

Exploring the Interaction Between Preschool Executive Control and Caregiver Emotion Socialization in Predicting Adolescent Weight Trajectories.

There is a critical need for research examining how neural vulnerabilities associated with obesity, including lower executive control, interact with family factors to impact weight trajectories across adolescence. Utilizing a longitudinal design, the present study investigated caregivers' emotion socialization practices as a moderator of the association between preschool executive control and adolescent body mass index (BMI) trajectories. Participants were 229 youth (Mage = 5.24, SD = 0.03; 47.2% assigned female at birth; 73.8% White, 3.9% Black, 0.4% Asian American, 21.8% multiracial; 12.7% Hispanic) enrolled in a longitudinal study. At preschool-age, participants completed performance-based executive control tasks, and their caregivers reported on their typical emotion-related socialization behaviors (i.e., supportive and nonsupportive responses to children's negative emotions). Participants returned for annual laboratory visits at ages 14 through 17, during which their height and weight were measured to calculate BMI. Although neither preschool executive control nor caregiver emotion-related socialization behaviors were directly associated with BMI growth in adolescence, supportive responses moderated the association between executive control and BMI trajectories. The expected negative association between lower preschool executive control and greater BMI growth was present at below average levels of supportive responses, suggesting that external regulation afforded by supportive responses might reduce risk for adolescent overweight and obesity among children with lower internal self-regulatory resources during preschool. Findings highlight the importance of efforts to bolster executive control early in development and targeted interventions to promote effective caregiver emotion socialization (i.e., more supportive responses) for youth with lower internal self-regulatory abilities to mitigate risk for overweight and obesity and promote health across childhood and adolescence.

Placental transcriptomic signatures of spontaneous preterm birth.

BACKGROUND: Spontaneous preterm birth accounts for most preterm births and leads to significant morbidity in the newborn and childhood period. This subtype of preterm birth represents an increasing proportion of all preterm births when compared with medically indicated preterm birth, yet it is understudied in omics analyses. The placenta is a key regulator of fetal and newborn health, and the placental transcriptome can provide insight into pathologic changes that lead to spontaneous preterm birth. OBJECTIVE: This analysis aimed to identify genes for which placental expression was associated with spontaneous preterm birth (including early preterm and late preterm birth). STUDY DESIGN: The ECHO PATHWAYS consortium extracted RNA from placental samples collected from the Conditions Affecting Neurocognitive Development and Learning in Early Childhood and the Global Alliance to Prevent Prematurity and Stillbirth studies. Placental transcriptomic data were obtained by RNA sequencing. Linear models were fit to estimate differences in placental gene expression between term birth and spontaneous preterm birth (including gestational age subgroups defined by the American College of Obstetricians and Gynecologists). Models were adjusted for numerous confounding variables, including labor status, cohort, and RNA sequencing batch. This analysis excluded patients with induced labor, chorioamnionitis, multifetal gestations, or medical indications for preterm birth. Our combined cohort contained gene expression data for 14,023 genes in 48 preterm and 540 term samples. Genes and pathways were considered statistically significantly different at false discovery rate-adjusted P value of <.05. RESULTS: In total, we identified 1728 genes for which placental expression was associated with spontaneous preterm birth with more differences in expression in early preterm samples than late preterm samples when compared with full-term samples. Of those, 9 genes were significantly decreased in both early and late spontaneous preterm birth, and the strongest associations involved placental expression of IL1B, ALPL, and CRLF1. In early and late preterm samples, we observed decreased expression of genes involved in immune signaling, signal transduction, and endocrine function. CONCLUSION: This study provides a comprehensive assessment of the differences in the placental transcriptome associated with spontaneous preterm birth with robust adjustment for confounding. Results of this study are in alignment with the known etiology of spontaneous preterm birth, because we identified multiple genes and pathways for which the placental and chorioamniotic membrane expression was previously associated with prematurity, including IL1B. We identified decreased expression in key signaling pathways that are essential for placental growth and function, which may be related to the etiology of spontaneous preterm birth. We identified increased expression of genes within metabolic pathways associated exclusively with early preterm birth. These signaling and metabolic pathways may provide clinically targetable pathways and biomarkers. The findings presented here can be used to understand underlying pathologic changes in premature placentas, which can inform and improve clinical obstetrics practice.

Does preschool executive control mediate the impact of early environmental unpredictability and deprivation on the general factor of psychopathology a decade later?

BACKGROUND: Although deprivation has been consistently shown to increase risk for psychopathology through impaired executive control, the unique effects of other dimensions of early adversity, such as unpredictability, on executive control development are poorly understood. The current study evaluated whether deprivation and/or unpredictability early in life have unique effects on the general factor of psychopathology through impaired preschool executive control. METHODS: Participants included 312 children (51% female) oversampled for greater sociodemographic risk. Preschool executive control was measured using a battery of nine developmentally appropriate executive control tasks. Dimensions of adversity were measured with observational and caregiver assessments, and psychopathology was measured with caregiver and child reports. RESULTS: In separate models, both deprivation and unpredictability had significant indirect effects on the adolescent general factor of psychopathology through impaired preschool executive control. However, when both dimensions of adversity were included simultaneously, early life deprivation, but not unpredictability, was uniquely associated with the general factor of psychopathology in adolescence through impaired preschool executive control. CONCLUSIONS: Preschool executive control appears to be a transdiagnostic mechanism through which deprivation, but not unpredictability, increases risk for the general factor of psychopathology in adolescence. Results elucidate potential transdiagnostic targets for intervention efforts aimed at reducing the development and maintenance of psychopathology across the life span.

Association of Gestational Diabetes Mellitus and Perinatal Maternal Depression with Early Childhood Behavioral Problems: An Environmental Influences on Child Health Outcomes (ECHO) Study.

This study examined the association of gestational diabetes mellitus (GDM), prenatal, and postnatal maternal depressive symptoms with externalizing, internalizing, and autism spectrum problems on the Preschool Child Behavior Checklist in 2379 children aged 4.12 ± 0.60 (48% female; 47% White, 32% Black, 15% Mixed Race, 4% Asian, <2% American Indian/Alaskan Native, <2% Native Hawaiian; 23% Hispanic). Data were collected from the NIH Environmental influences on Child Health Outcomes (ECHO) Program from 2009-2021. GDM, prenatal, and postnatal maternal depressive symptoms were each associated with increased child externalizing and internalizing problems. GDM was associated with increased autism behaviors only among children exposed to perinatal maternal depressive symptoms above the median level. Stratified analyses revealed a relation between GDM and child outcomes in males only.

Intergenerational transmission of stress: Multi-domain stressors from maternal childhood and pregnancy predict children's mental health in a racially and socioeconomically diverse, multi-site cohort.

PURPOSE: Despite growing recognition that unfortunately common maternal stress exposures in childhood and pregnancy may have intergenerational impacts on children's psychiatric health, studies rarely take a life course approach. With child psychopathology on the rise, the identification of modifiable risk factors is needed to promote maternal and child well-being. In this study, we examined associations of maternal exposure to childhood traumatic events (CTE) and pregnancy stressful life events (PSLE) with child mental health problems in a large, sociodemographically diverse sample. METHODS: Participants were mother-child dyads in the ECHO-PATHWAYS consortium's harmonized data across three U.S. pregnancy cohorts. Women completed questionnaires regarding their own exposure to CTE and PSLE, and their 4-6-year-old child's mental health problems using the Child Behavior Checklist (CBCL). Regression analyses estimated associations between stressors and child total behavior problems, adjusting for confounders. RESULTS: Among 1948 dyads (child age M = 5.13 (SD = 1.02) years; 38% Black, 44% White; 8.5% Hispanic), maternal history of CTE and PSLE were independently associated with children's psychopathology: higher CTE and PSLE counts were related to higher total problems ([ßCTE = 0.11, 95% CI [.06, .16]; ßSLE = 0.21, 95% CI [.14, 0.27]) and greater odds of clinical levels of problems (ORCTE = 1.41; 95% CI [1.12, 1.78]; ORPSLE = 1.36; 95% CI [1.23, 1.51]). Tests of interaction showed PSLEs were more strongly associated with child problems for each additional CTE experienced. CONCLUSION: Findings confirm that maternal exposure to CTE and PSLE are independently associated with child mental health, and history of CTE exacerbates the risk associated with PSLE, highlighting intergenerational risk pathways for early psychopathology. Given the prevalence of these exposures, prevention and intervention programs that reduce childhood trauma and stress during pregnancy will likely positively impact women's and their children's health.

Social Network Analysis of Diffusion Among American Indian Youth in a Culturally Adapted, Family-focused Prevention Program.

Diffusion can contribute to the spread of preventive intervention effects from participants to non-participants, but best practices for randomized trials prevent contamination of conditions. These practices conflict with cultural values of community benefit, which are salient among American Indians. This study embedded social network measures within a randomized trial of the Bii-Zin-Da-De-Dah (BZDDD) family-focused prevention program to characterize youth's social networks, describe the nature and content of sharing, and test for diffusion effects on cultural engagement (ethnic identification, cultural socialization, cultural practices) and substance use. Participants were 256 American Indian youths enrolled in the trial who provided self-reports of their social networks and indicated whether specific program content was shared with or received from others, while completing cultural engagement and substance use questionnaires across three waves. Results indicated that social networks were comprised mainly of peers and same-age family members (e.g., cousins). Program sharing was not uncommon. For example, 51% of responding intervention youth reported talking with non-participants about BZDDD at wave 2, typically (53%) with similar-age friends and family who were, most often (71%), out of the home. Evidence for diffusion effects was limited, but did indicate that control youth who had some exposure to BZDDD had a significantly higher average cultural/ethnic identity scale score at wave 2 and were more likely to ask an elder for advice than control youth who had no BZDDD exposure in adjusted analyses. Findings illustrate the value of measuring and testing for potential effects of diffusion in prevention trials with American Indians.

The association between duration of breastfeeding and childhood asthma outcomes.

BACKGROUND: Postnatal exposures, including breastfeeding, may influence asthma development. OBJECTIVE: To investigate the association between breastfeeding duration and child asthma. METHODS: We studied 2021 mother-child dyads in the ECHO PATHWAYS consortium of prospective pregnancy cohorts (GAPPS, CANDLE, TIDES). Women reported the duration of any and exclusive breastfeeding and child asthma outcomes during follow-up at child age 4 to 6 years. Outcomes included current wheeze (previous 12 months), ever asthma, current asthma (having ≥2 of current wheeze, ever asthma, medication use in past 12-24 months), and strict current asthma (ever asthma with either or both current wheeze and medication use in past 12-24 months). We used multivariable logistic regression to assess associations (odds ratios and 95% confidence intervals) between breastfeeding and asthma outcomes adjusting for potential confounders. We assessed effect modification by mode of delivery, infant sex, and maternal asthma. RESULTS: Among women, 33%, 13%, 9%, and 45% reported 0 to less than 2, 2 to 4, 5 to 6, and more than 6 months of any breastfeeding, respectively. The duration of any breastfeeding had a protective linear trend with ever asthma but no other outcomes. There was a duration-dependent protective association of exclusive breastfeeding and child asthma outcomes (eg, current asthma adjusted odds ratio [95% confidence interval], 0.64 [0.41-1.02], 0.61 [0.38-0.98], and 0.52 (0.31-0.87) for 2to 4 months, 5 to 6 months, and more than 6 months, respectively, compared with <2 months). For exclusive breastfeeding, protective associations were stronger in dyads with children born by vaginal vs cesarean delivery although interactions did not reach statistical significance (Pinteractions 0.12-0.40). CONCLUSION: Longer duration of exclusive breastfeeding had a protective association with child asthma.

Gestational diabetes mellitus, prenatal maternal depression, and risk for postpartum depression: an Environmental influences on Child Health Outcomes (ECHO) Study.

BACKGROUND: Prior research has demonstrated bidirectional associations between gestational diabetes mellitus (GDM) and perinatal maternal depression. However, the association between GDM, prenatal depression, and postpartum depression (PPD) has not been examined in a prospective cohort longitudinally. METHODS: Participants in the current analysis included 5,822 women from the National Institutes of Health's Environmental influences on Child Health Outcomes (ECHO) Research Program: N = 4,606 with Neither GDM nor Prenatal Maternal Depression (Reference Category); N = 416 with GDM only; N = 689 with Prenatal Maternal Depression only; and N = 111 with Comorbid GDM and Prenatal Maternal Depression. The PROMIS-D scale was used to measure prenatal and postnatal maternal depressive symptoms. Primary analyses consisted of linear regression models to estimate the independent and joint effects of GDM and prenatal maternal depression on maternal postpartum depressive symptoms. RESULTS: A higher proportion of women with GDM were classified as having prenatal depression (N = 111; 21%) compared to the proportion of women without GDM who were classified as having prenatal depression (N = 689; 13%), however this finding was not significant after adjustment for covariates. Women with Comorbid GDM and Prenatal Maternal Depression had significantly increased postpartum depressive symptoms measured by PROMIS-D T-scores compared to women with Neither GDM nor Prenatal Maternal Depression (mean difference 7.02, 95% CI 5.00, 9.05). Comorbid GDM and Prenatal Maternal Depression was associated with an increased likelihood of PPD (OR 7.38, 95% CI 4.05, 12.94). However, women with GDM only did not have increased postpartum PROMIS-D T-scores or increased rates of PPD. CONCLUSIONS: Our findings underscore the importance of universal depression screening during pregnancy and in the first postpartum year. Due to the joint association of GDM and prenatal maternal depression on risk of PPD, future studies should examine potential mechanisms underlying this relation.

Associations of prenatal metabolomics profiles with early childhood growth trajectories and obesity risk in African Americans: the CANDLE study.

OBJECTIVE: Prenatal metabolomics profiles, providing measures of in utero nutritional and environmental exposures, may improve the prediction of childhood outcomes. We aimed to identify prenatal plasma metabolites associated with early childhood body mass index (BMI) trajectories and overweight/obesity risk in offspring. METHODS: This study included 450 African American mother-child pairs from the Conditions Affecting Neurocognitive Development and Learning in Early Childhood Study. An untargeted metabolomics analysis was performed on the mothers' plasma samples collected during the second trimester. The children's BMI-z-score trajectories from birth to age 4 [rising-high- (9.8%), moderate- (68.2%), and low-BMI (22.0%)] and overweight/obesity status at age 4 were the main outcomes. The least absolute shrinkage and selection operator (LASSO) was used to select the prenatal metabolites associated with childhood outcomes. RESULTS: The mothers were 24.5 years old on average at recruitment, 76.4% having education less than 12 years and 80.0% with Medicaid or Medicare. In LASSO, seven and five prenatal metabolites were associated with the BMI-z-score trajectories and overweight/obese at age 4, respectively. These metabolites are mainly from/relevant to the pathways of steroid biosynthesis, amino acid metabolism, vitamin B complex, and xenobiotics metabolism (e.g., caffeine and nicotine). The odds ratios (95% CI) associated with a one SD increase in the prenatal metabolite risk scores (MRSs) constructed from the LASSO-selected metabolites were 2.97 (1.95-4.54) and 2.03 (1.54-2.67) for children being in the rising-high-BMI trajectory group and overweight/obesity at age 4, respectively. The MRSs significantly improved the risk prediction for childhood outcomes beyond traditional prenatal risk factors. The increase (95% CI) in the area under the receiver operating characteristic curves were 0.10 (0.03-0.18) and 0.07 (0.02-0.12) for the rising-high-BMI trajectory (P = 0.005) and overweight/obesity at age 4 (P = 0.007), respectively. CONCLUSIONS: Prenatal metabolomics profiles advanced prediction of early childhood growth trajectories and obesity risk in offspring.

Associations between specific components of executive control and eating behaviors in adolescence: A study using objective and subjective measures.

A growing literature suggests that executive control (EC; also known as "executive functioning" or "EF") in adolescence may play an important role in the development of key health behaviors, including eating behaviors. However, existing literature has significant limitations in the conceptualization and measurement of EC. The current study aims to address these limitations by employing a multidimensional approach to conceptualizing and measuring adolescent EC, including both objective and subjective measures covering multiple components of EC, and examining links with specific eating behaviors. A community sample of adolescents (N = 208; mean age = 14.5 years) completed a battery of performance-based neuropsychological tasks assessing specific components of EC (i.e., working memory, inhibitory control, flexible shifting), a norm-referenced questionnaire covering problems with specific components of EC in daily life, and a measure assessing key eating behaviors (i.e., uncontrolled eating, emotional eating, cognitive restraint). Objectively-measured adolescent working memory was significantly and uniquely associated with cognitive restraint, with stronger working memory associated with less cognitive restraint. No other associations between performance-based EC tasks and eating behaviors were found. In contrast, using subjective reports of EC, problems with inhibitory control were associated with greater uncontrolled eating, and problems with flexible shifting were associated with greater emotional eating. The results suggest links between specific aspects of EC and specific eating behaviors in adolescence, as well as the potential importance of context for understanding the role of EC in eating behavior. Given evidence that EC is modifiable, the findings have potential implications for novel interventions addressing eating behaviors by targeting EC.

Associations of Early Socio-familial Stress with Maladaptive and Adaptive Functioning in Middle Childhood: Roles of Executive Control and Foundational Cognitive Abilities.

This study examined whether cognitive processes in preschool, conceptualized as a unitary construct of executive control (EC) as well as foundational cognitive abilities (FCA), predict both maladaptive and adaptive functioning in middle childhood and mediate associations between early childhood socio-familial stress and those functional outcomes. Performance-based, multidimensional, and age-appropriate measures of EC and FCA were collected in a laboratory setting from 313 preschool-age children at age 5, along with questionnaire data from children and their parents on three dimensions of early socio-familial stress and parent smoking. Parent, teacher, and child self-report data on 285 of these children were obtained when they were in grade 3 or 4. Middle childhood data were used to create indices of maladaptive and adaptive functioning. A bi-factor structural equation modeling analysis captured distinct dimensions of preschool EC and FCA and was used to test the hypothesized pathways. EC had a statistically significant negative association with later maladaptive functioning. FCA, but not EC, served as a mediator in links between each type of family stressor and both maladaptive and adaptive functioning in middle childhood. Results suggest that EC may play a role in predicting maladaptation, whereas early childhood FCA may operate as an intervening variable in pathways from early family stressors to subsequent maladaptation as well as adaptation. Findings point to the need to address FCA by reducing early family stressors. Early interventions that enhance cognitive abilities may help reduce maladaptive and promote adaptive functioning later in childhood, thereby potentially preventing, in turn, later behavioral problems.

Parental Alcohol Use and the Alcohol Misuse of their Offspring in a Finnish Birth Cohort: Investigation of Developmental Timing.

There is a positive association between parental alcohol use and the alcohol use of their offspring. It is less clear whether this relation exists at different developmental periods. The purpose of the current study was to examine the associations between parental alcohol use at two developmental periods (prenatal and adolescence) and the alcohol misuse of their offspring at two developmental periods (adolescence and young adulthood). Data from the Northern Finland Birth Cohort 1986 (NFBC1986; n = 6963; 51% of offspring were girls) were used. The NFBC1986 is a population-based study of individuals born during a 1-year period in Finland. Multi-informant (parent, teacher, and youth) and multi-method (surveys and population registers) data were collected at four developmental periods (prenatal, childhood, adolescence, and young adulthood). The findings indicated that parents' alcohol use was stable from the prenatal period to adolescence. Mothers' and fathers' (based on mothers' perceptions) alcohol use during the prenatal period and adolescence were directly related to adolescents' heavy drinking. Prenatal alcohol use by mothers and fathers were related to young adults' alcohol use disorder indirectly (but not directly) through mothers' and fathers' alcohol use during adolescence and then through adolescents' heavy drinking. The results suggest that early and ongoing screening for alcohol use by mothers and fathers could help identify individuals at risk for heavy drinking and alcohol-related problems during adolescence and young adulthood.

Executive Control in Early Childhood as an Antecedent of Adolescent Problem Behaviors: A Longitudinal Study with Performance-based Measures of Early Childhood Cognitive Processes.

Identifying childhood cognitive processes that predict adolescent problem behaviors can help guide understanding and prevention of these behaviors. In a community sample of 313 youth recruited in a small Midwestern city between 2006 and 2012 (49% male, 64% European American), executive control and foundational cognitive abilities were assessed at age 5 in a lab setting with performance-based measures. In adolescence, youth provided self-report of problem behaviors in surveys administered annually between ages 14 and 16. Executive control was negatively associated with externalizing behavior problems and adolescents getting in trouble at school, accounting for foundational cognitive abilities and family background covariates. Executive control had negative, but nonsignificant, associations with internalizing problems and substance use initiation. The findings point to deficits in executive control as a childhood risk factor for later problems and a potential target for preventive interventions.

Psychometrics of a Brief Trauma Symptom Screen for Youth in Residential Care.

Trauma screening is an important element for providing trauma-informed services to youth in residential care. Unfortunately, lack of time and resources may deter clinicians from conducting trauma screening at intake. This study tested the psychometric properties of the Brief Trauma Symptom Screen for Youth (BTSSY), which could be used during intake into residential care. Participants included 572 youth, ages 10-18 years (M = 14.28 years, SD = 2.31), of whom 58.9% were boys, 78.7% were Caucasian, 51.7% were youth receiving services in residential care, 15.6% were youth with clinical needs, and 32.7% were typically developing youth from the local community. Participants completed the BTSSY; other questionnaires of psychopathology, childhood maltreatment, and symptomology of posttraumatic stress disorder (PTSD); and diagnostic interviews, which were conducted by licensed psychiatrists. The total BTSSY score had a good composite reliability (CR) of .80 and was valid based on a significant positive correlation, r = .64, with the UCLA PTSD-Reaction Index. The BTSSY score was also fair, area under the curve = .75, at detecting a diagnosis of PTSD from a psychiatrist. Significant group differences in the BTSSY scores were found between youth with a diagnosis of PTSD and the other two groups, with moderate-to-large effect sizes, ds = 0.73-1.22. Preliminary results indicated the BTSSY may be a useful screening tool for identifying youth at residential care intake who may need additional assessment for PTSD. Limitations and implications for future research and practice are discussed.

Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Psicometría de la escala breve de síntomas de trauma para jóvenes en atención residencial TAMIZAJE BREVE DE SÍNTOMAS DE TRAUMA PARA JOVENES La detección de los traumas es un elemento importante para proporcionar servicios informados en el trauma a los jóvenes en atención residencial. Desafortunadamente, la falta de tiempo y recursos puede impedir a los médicos realizar detección de traumas en el ingreso. Este estudio probó las propiedades psicométricas de la Escala Breve de Síntomas de Trauma para Jóvenes (BTSSY en su sigla en inglés), que podría usarse durante el ingreso a la atención residencial. Los participantes incluyeron 572 jóvenes, de 10 a 18 años (M = 14.28 años, DE = 2.31), de los cuales 58.9% eran niños, 78.7% eran caucásicos, 51.7% eran jóvenes que recibían servicios de atención residencial, 15.6% eran jóvenes con necesidades clínicas, y 32.7% eran jóvenes con desarrollo normativo de la comunidad local. Los participantes completaron el BTSSY; otros cuestionarios de psicopatología, maltrato infantil, y sintomatología del trastorno de estrés postraumático (TEPT); y entrevistas de diagnóstico, realizadas por psiquiatras calificados. El puntaje BTSSY total tuvo una buena confiabilidad compuesta (CR en su sigla en inglés) de .80 y fue válido en base a una correlación positiva significativa, r = .64, con el Índice de Reacción del TEPT de UCLA. El puntaje BTSSY también fue favorable, área bajo la curva = .75, al detectar un diagnóstico del TEPT de un psiquiatra. Se encontraron diferencias significativas entre los grupos en los puntajes BTSSY entre los jóvenes con diagnóstico del TEPT y los otros dos grupos, con tamaños del efecto moderados a grandes, ds = 0.73-1.22. Los resultados preliminares indicaron que el BTSSY puede ser una herramienta útil de detección para identificar a los jóvenes que reciben atención residencial y que pueden necesitar una evaluación adicional para el TEPT. Se discuten las limitaciones e implicaciones para futuras investigaciones y la práctica.

Associations of Cumulative Family Risk With Academic Performance and Substance Involvement: Tests of Moderation by Child Reading Engagement.

Background: Exposure to cumulative contextual risk within the family early in life increases children's risk for substance involvement and related difficulties, including school failure, in adolescence and young adulthood. However, potential protective factors that buffer these risk associations are relatively untested, yet such tests are needed to improve existing preventive interventions for enhancing resilience among vulnerable children. Objectives: This study tested child reading engagement with parents at home as a moderator of cumulative family risk associations with adolescent substance use and academic performance as well as young adult substance abuse. Methods: Population register data as well as parent-report and adolescent-report data from 6,963 participants of the 1986 Northern Finland Birth Cohort study were analyzed via structural equation modeling with latent variable interactions. Results: Results showed that child reading engagement moderated the associations of cumulative family risk with both adolescent academic performance and young adult substance abuse, but not with adolescent substance use. The highest levels of academic performance were observed under conditions of low risk and high reading engagement. Interestingly, cumulative family risk had a small positive association with substance abuse when reading engagement was low and a negative association with the young adult outcome when reading engagement was high. Conclusions/Importance: Moderation tests revealed complex interaction forms that may have implications for both theory and family-based preventive interventions.

Prospective relations between alexithymia, substance use and depression: findings from a National Birth Cohort.

Purpose: This study examined a developmental model that links affect-regulation difficulties in childhood with three dimensions of alexithymia in adolescence (difficulty identifying feelings, difficulty describing feelings, and externally oriented thinking) and substance use and depression in adulthood, while accounting for cumulative contextual risk in childhood, and testing potential gender moderation. Methods: Multiple group path analyses were conducted using data from the Northern Finland Birth Cohort 1986 (N = 6963). Analyses used data collected during prenatal/birth, childhood, adolescence, and young adulthood periods. Results: Our examination of early precursors for alexithymia indicated that the associations of affect-regulation problems in childhood with alexithymia were stronger for girls, potentially putting girls with affect-regulation difficulties in childhood at higher risk for developing alexithymia in adolescence. The associations of cumulative contextual risk in childhood with alexithymia, substance use disorder, and depression diagnosis in adulthood were significant for both girls and boys. Our findings in regard to substance use and depression disorders revealed that alexithymia in adolescence predicted depression diagnosis in adulthood, particularly due to a contribution from the alexithymia domain of 'difficulties identifying feelings.' However, none of the alexithymia domains was directly associated with substance use disorder in adulthood. Conclusions: Our study contributes to research that links alexithymia with difficulties in affect regulation and cumulative contextual risk in childhood, yielding findings that may be relevant for preventive interventions.

Youth Needs at Intake into Trauma-Informed Group Homes and Response to Services: An Examination of Trauma Exposure, Symptoms, and Clinical Impression.

Trauma-informed care is recommended to improve the quality of group home services for youth. Youth exposure to trauma and associated symptoms are important factors involved in making the clinical impression that determines treatment services. This study considered three dimensions of trauma (exposure, symptoms, and clinical impression) to determine associations with behavioral incidents of youth in trauma-informed group homes and how trauma was related to changes in psychopathology from intake to discharge. Archival records of youth (N = 1,096), age 9-18 (M = 15.7 years) who received services from January 2013 to December 2017, and departed the program were used. Statistical procedures included hierarchical linear modeling and analysis of covariance. Results indicated trauma symptoms predicted emotional problems and self-injurious behavior. Youth in high- and low-trauma groups both showed decreases in behavioral incidents and psychopathology, but clinical impression of trauma moderated the change in emotional problems from intake to discharge. Youth deemed by clinicians to have lower trauma (based on history of maltreatment and expression of trauma symptoms) had greater decrease in emotional problems from admission to discharge. Limitations and implications for further research on implementation and effectiveness of trauma-informed models are discussed.

Testing a Model of Universal Prevention Effects on Adolescent Relationships and Marijuana Use as Pathways to Young Adult Outcomes.

There are several interrelated knowledge gaps in the literature on skills-building interventions for middle schoolers designed to prevent initiation of substance use, all of which concern the limited study of the adolescent pathways of those intervention effects on distal young adult outcomes. Among the most important yet understudied pathways of influence on long-term effects are positive youth relationship outcomes of middle-school interventions. Other influential pathways for long-term effects are reductions in adolescent substance misuse, particularly marijuana use, considering the long-term consequences of early marijuana initiation. To address these knowledge gaps, data from a randomized controlled trial were used to test a longitudinal, developmental model positing pathways of intervention effects on age 21 illicit drug use and positive relationship affect, via earlier effects on adolescent relationships and marijuana use. Sixth-graders and their families enrolled in 22 Iowa schools were randomly assigned to the Iowa Strengthening Families Program or a control group (N = 446). The average age of students at baseline was 11.3 years (10-13 year age range); 48% were male and 98% were Caucasian, reflective of the demographics in the participating rural Midwest communities. Measures included middle-school relationships (parents, peers, school), high school marijuana use, plus age 21 illicit drug use and relationship affect (parents, work, school), 10 years past intervention implementation. As expected, intervention effects on young adult variables were indirect, through effects on adolescent outcomes, with higher-risk participants showing greater intervention impact. The findings suggest preventive interventions with young adolescents have potential to demonstrate effects into young adulthood.
