Cumulative psychosocial risk and early child development: validation and use of the Childhood Psychosocial Adversity Scale in global health research.
Ontology highlight
ABSTRACT: Background
Evidence suggests that cumulative early psychosocial adversity can influence early child development (ECD). The Childhood Psychosocial Adversity Scale (CPAS) is a novel measure of cumulative risk designed for use in global ECD research. We describe its development and assess validity from its first application in Bangladesh, where it predicts cognitive development scores among young children.Methods
Items were generated from literature review and qualitatively assessed for local relevance. Two-hundred and eighty-five mother-child dyads from an urban slum of Dhaka completed the CPAS at child ages 18, 24, 48, and/or 60 months. The CPAS was assessed for internal consistency, retest reliability, and convergent, incremental, and predictive validity.Results
The CPAS includes subscales assessing child maltreatment, caregiver mental health, family conflict, domestic violence, and household/community psychosocial risks. In Bangladesh, subscales had good internal consistency (Cronbach's α > 0.70). Full-scale score had good 2-week test-retest reliability (intra-class correlation coefficient = 0.89; F(38,38) = 8.45, p < 0.001). Using multivariate regression, 48-month CPAS score significantly predicted 60-month intelligence quotient, accounting for more variance than socioeconomic status or malnutrition.Conclusions
The CPAS is a novel tool assessing cumulative childhood psychosocial risk. Evidence supports validity of its use in ECD research in Bangladesh, and ongoing work is applying it in additional countries.

Project description:BackgroundThe long-term cumulative impact of exposure to childhood adversity is well documented. There is an increasing body of literature examining protective factors following childhood adversity. However, no known reviews have summarised studies examining protective factors for broad psychosocial outcomes following childhood adversity.AimsTo summarise the current evidence from longitudinal studies of protective factors for adult psychosocial outcomes following cumulative exposure to childhood adversity.MethodWe conducted a formal systematic review of studies that were longitudinal; were published in a peer-reviewed journal; examined social, environmental or psychological factors that were measured following a cumulative measure of childhood adversity; and resulted in more positive adult psychosocial outcomes.ResultsA total of 28 studies from 23 cohorts were included. Because of significant heterogeneity and conceptual differences in the final sample of articles, a meta-analysis was not conducted. The narrative review identified that social support is a protective factor specifically for mental health outcomes following childhood adversity. Findings also suggest that aspects of education are protective factors to adult socioeconomic, mental health and social outcomes following childhood adversity. Personality factors were protective for a variety of outcomes, particularly mental health. The personality factors were too various to summarise into meaningful combined effects. Overall GRADE quality assessments were low and very low, although these scores mostly reflect that all observational studies are low quality by default.ConclusionsThese findings support strategies that improve connection and access to education following childhood adversity exposure. Further research is needed for the roles of personality and dispositional factors, romantic relationship factors and the combined influences of multiple protective factors.

Project description:BackgroundThe association between adversity and psychopathology in adolescents and adults is characterized by equifinality. These associations, however, have not been assessed during early childhood when psychopathology first emerges. Defining adversity using both dimensional and cumulative risk approaches, we examined whether specific types of adversity are differentially associated with psychopathology in preschool-aged children.MethodsMeasures of threat, deprivation, and total adversities (i.e., cumulative risk) were calculated based on parent-reported information for 755 2- to 5-year old children recruited from pediatric primary care clinics. Logistic regression was used to estimate cross-sectional associations between type of adversity and anxiety, depression, ADHD, and behavioral disorder diagnoses.ResultsThreat and cumulative risk exhibited independent associations with psychopathology. Threat was strongly related to behavioral disorders. Cumulative risk was consistently related to all psychopathologies.ConclusionsUsing mutually adjusted models, we identified differential associations between threat and psychopathology outcomes in preschool-aged children. This selectivity may reflect different pathways through which adversity increases the risk for psychopathology during this developmentally important period. As has been observed at other ages, a cumulative risk approach also effectively identified the cumulative impact of all forms of adversity on most forms of psychopathology during early childhood.

Project description:BackgroundThe lack of culturally adapted and validated instruments for child mental health and psychosocial support in low and middle-income countries is a barrier to assessing prevalence of mental health problems, evaluating interventions, and determining program cost-effectiveness. Alternative procedures are needed to validate instruments in these settings.MethodsSix criteria are proposed to evaluate cross-cultural validity of child mental health instruments: (i) purpose of instrument, (ii) construct measured, (iii) contents of construct, (iv) local idioms employed, (v) structure of response sets, and (vi) comparison with other measurable phenomena. These criteria are applied to transcultural translation and alternative validation for the Depression Self-Rating Scale (DSRS) and Child PTSD Symptom Scale (CPSS) in Nepal, which recently suffered a decade of war including conscription of child soldiers and widespread displacement of youth. Transcultural translation was conducted with Nepali mental health professionals and six focus groups with children (n=64) aged 11-15 years old. Because of the lack of child mental health professionals in Nepal, a psychosocial counselor performed an alternative validation procedure using psychosocial functioning as a criterion for intervention. The validation sample was 162 children (11-14 years old). The Kiddie-Schedule for Affective Disorders and Schizophrenia (K-SADS) and Global Assessment of Psychosocial Disability (GAPD) were used to derive indication for treatment as the external criterion.ResultsThe instruments displayed moderate to good psychometric properties: DSRS (area under the curve (AUC)=0.82, sensitivity=0.71, specificity=0.81, cutoff score ? 14); CPSS (AUC=0.77, sensitivity=0.68, specificity=0.73, cutoff score ? 20). The DSRS items with significant discriminant validity were "having energy to complete daily activities" (DSRS.7), "feeling that life is not worth living" (DSRS.10), and "feeling lonely" (DSRS.15). The CPSS items with significant discriminant validity were nightmares (CPSS.2), flashbacks (CPSS.3), traumatic amnesia (CPSS.8), feelings of a foreshortened future (CPSS.12), and easily irritated at small matters (CPSS.14).ConclusionsTranscultural translation and alternative validation feasibly can be performed in low clinical resource settings through task-shifting the validation process to trained mental health paraprofessionals using structured interviews. This process is helpful to evaluate cost-effectiveness of psychosocial interventions.

Project description:Importance:Childhood adversity (CA) is associated with an increased risk of suicide in young adulthood that might be explained by maladaptive trajectories during adolescence. Although adolescent violent offending is linked with suicide, little is known about its role in the association between CA and suicide. Objective:To examine whether adolescent violent offending mediates the association between CA and suicide in early adulthood. Design, Setting, and Participants:This population-based, longitudinal cohort study with a follow-up time spanning 5 to 9 years included 476?103 individuals born in Sweden between 1984 and 1988. The study population was prospectively followed up from 20 years of age until December 31, 2013, with respect to suicide. Data analysis was performed from January 1, 1984, to December 31, 2013. Exposures:Register-based CAs included parental death, parental substance abuse and psychiatric disorder, parental criminal offending, parental separation, public assistance recipiency, child welfare intervention, and residential instability. Adolescent violent offending was defined as being convicted of a violent crime between the ages of 15 and 19 years. Main Outcomes and Measures:Estimates of risk of suicide after 20 years of age (from 2004 if born in 1984 and from 2008 if born in 1988) until the end of 2013 were calculated as incidence rate ratios (IRRs) with 95% CIs using Poisson regression analysis. Adjustments were made for demographics and psychiatric disorder. In addition, binary mediation analysis with logistic regression was used. Results:A total of 476?103 individuals (231 699 [48.7%] female) were included in the study. Those with a conviction for violent offending had been exposed to all CAs to a greater extent than those with no violent offending. Cumulative CA was associated with risk of suicide in nonconvicted (adjusted IRR, 2.4; 95% CI, 1.5-3.9) and convicted youths, who had a higher risk of suicide (adjusted IRR, 8.5; 95% CI, 4.6-15.7). Adolescent violent offending partly mediated the association between CA and suicide. Conclusions and Relevance:Individuals with a history of CA who also engage in violent offending in adolescence have a high risk of suicide. Interventions to prevent externalizing behavior during childhood and increased support to youths with delinquent behavior may have the potential to prevent suicide related to CA.

Project description:ObjectiveAdverse childhood experiences may be associated with cardiometabolic morbidity and mortality in adulthood. There is heterogeneity in this literature regarding the type of items in cumulative adversity indices, sample sizes, demographics, and covariates. The present review used quantitative meta-analysis to examine this association and potential moderators.MethodIncluded studies had a measure of cumulative adversity (an index of at least 2 adverse childhood experiences from age 0 to 18) and a measure of cardiometabolic disease: cardiovascular disease (CVD) clinical outcomes (hypertension, coronary heart disease, ischemic heart disease, myocardial infarction, stroke, cerebrovascular disease) and metabolic outcomes (diabetes, metabolic syndrome) at age 18 or older. Given different interpretations of odds ratios (OR) versus hazard ratios (HR), effects were pooled separately. Overall, 9 HR studies (15 effects) based on 179,612 participants and 29 OR studies (62 effects) based on 247,393 participants were included.ResultsOn the basis of retrospectively assessed adversity, combined studies showed a significant estimated effect of cumulative childhood adversity on adult cardiometabolic disease (HR = 1.42, 95% CI [1.20, 1.67]; OR = 1.36 [1.27, 1.46]). Results varied somewhat by type of cardiometabolic disease, analytic strategy, and number and type of covariates.ConclusionsThe literature suggests that cumulative childhood adversity is modestly related to adult cardiometabolic disease, with effects somewhat stronger for CVD clinical outcomes. The absence of a consistent operational and conceptual definition of adversity and paucity of prospective designs temper the conclusions. It is time for further evaluation of the types and timing of childhood events that have maximal impact on adult cardiometabolic disease. (PsycINFO Database Record

Project description:BackgroundAdverse childhood experiences (ACEs) negatively impact health throughout the life course. For children exposed to ACEs, resilience may be particularly important. However, the literature regarding resilience, particularly the self-regulation aspect of resilience, is not often described in children with ACEs. Additionally, family and community factors that might help promote resilience in childhood may be further elucidated. We aimed to describe the relationship between ACEs and parent-perceived resilience in children and examine the child, family, and community-level factors associated with child resilience.MethodsUsing the US-based, 2011-2012 National Survey of Children's Health, we examined adverse childhood experiences (NSCH-ACEs) as the main exposure. Affirmative answers to adverse experiences generated a total parent-reported NSCH-ACE score. Bivariate and multivariable logistic regression models were constructed for parent-perceived child resilience and its association with ACEs, controlling for child, family, and neighborhood-level factors.ResultsAmong 62,200 US children 6-17 years old, 47% had 0 ACEs, 26% had 1 ACE, 19% had 2-3 ACEs, and 8% had 4 or more ACEs. Child resilience was associated with ACEs in a dose-dependent relationship: as ACEs increased, the probability of resilience decreased. This relationship persisted after controlling for child, family, and community factors. Specific community factors, such as neighborhood safety (p < .001), neighborhood amenities (e.g., libraries, parks) (p < .01) and mentorship (p < .05), were associated with significantly higher adjusted probabilities of resilience, when compared to peers without these specific community factors.ConclusionsWhile ACEs are common and may be difficult to prevent, there may be opportunities for health care providers, child welfare professionals, and policymakers to strengthen children and families by supporting community-based activities, programs, and policies that promote resilience in vulnerable children and communities in which they live.

Project description:In humans and other animals, harsh circumstances in early life predict morbidity and mortality in adulthood. Multiple adverse conditions are thought to be especially toxic, but this hypothesis has rarely been tested in a prospective, longitudinal framework, especially in long-lived mammals. Here we use prospective data on 196 wild female baboons to show that cumulative early adversity predicts natural adult lifespan. Females who experience ≥3 sources of early adversity die a median of 10 years earlier than females who experience ≤1 adverse circumstances (median lifespan is 18.5 years). Females who experience the most adversity are also socially isolated in adulthood, suggesting that social processes partially explain the link between early adversity and adult survival. Our results provide powerful evidence for the developmental origins of health and disease and indicate that close ties between early adversity and survival arise even in the absence of health habit and health care-related explanations.

Project description:Studies of the early-life origins of adult physical functioning and mortality have found that childhood health and socioeconomic context are important predictors, often irrespective of adult experiences. However, these studies have generally assessed functioning and mortality as distinct processes and used cross-sectional prevalence estimates that neglect the interplay of disability incidence, recovery, and mortality. Here, we examine whether early-life disadvantages both shorten lives and increase the number and fraction of years lived with functional impairment. We also examine the degree to which educational attainment mediates and moderates the health consequences of early-life disadvantages. Using the 1998-2008 Health and Retirement Study, we examine these questions for non-Hispanic whites and blacks aged 50-100 years using multistate life tables. Within levels of educational attainment, adults from disadvantaged childhoods lived fewer total and active years, and spent a greater portion of life impaired compared with adults from advantaged childhoods. Higher levels of education did not ameliorate the health consequences of disadvantaged childhoods. However, because education had a larger impact on health than did childhood socioeconomic context, adults from disadvantaged childhoods who achieved high education levels often had total and active life expectancies that were similar to or better than those of adults from advantaged childhoods who achieved low education levels.

Project description:Fifteen-year-old adolescents (N = 109) in a longitudinal study of child development were recruited to examine differences in DNA methylation in relation to parent reports of adversity during the adolescents’ infancy and preschool periods. Microarray technology applied to 28,000 cytosine–guanine dinucleotide sites within DNA derived from buccal epithelial cells showed differential methylation among adolescents whose parents reported high levels of stress during their children’s early lives. Maternal stressors in infancy and paternal stressors in the preschool years were most strongly predictive of differential methylation, and the patterning of such epigenetic marks varied by children’s gender. To the authors’ knowledge, this is the first report of prospective associations between adversities in early childhood and the epigenetic conformation of adolescents’ genomic DNA. Genomic DNA was extracted from 109 Buccal DNA samples, bisulphite converted and hybridized, along with 4 technical replicates to the Illumina Infinium HumanMethylation27 Beadchip v1.2 for genome wide DNA methylation profiling. Processed signal intensity data and Detection Pvalues for individual replicates of Samples 006 (reps a,b), 099 (reps a,b,c), 106 (reps a,b) reported in the supplementary file "processed_individual reps.txt."
