Capturing Environmental Dimensions of Adversity and Resources in the Context of Poverty Across Infancy Through Early Adolescence: A Moderated Nonlinear Factor Model.

ABSTRACT: Income, education, and cumulative-risk indices likely obscure meaningful heterogeneity in the mechanisms through which poverty impacts child outcomes. This study draws from contemporary theory to specify multiple dimensions of poverty-related adversity and resources, with the aim of better capturing these nuances. Using data from the Family Life Project (N = 1,292), we leveraged moderated nonlinear factor analysis (Bauer, 2017) to establish group- and longitudinally invariant environmental measures from infancy to early adolescence. Results indicated three latent factors-material deprivation, psychosocial threat, and sociocognitive resources-were distinct from each other and from family income. Each was largely invariant across site, racial group, and development and showed convergent and discriminant relations with age-twelve criterion measures. Implications for ensuring socioculturally valid measurements of poverty are discussed.

Project description:ObjectiveThe study aims to evaluate the association between exposure to childhood adversity and insomnia, with an emphasis on the role of adversity type, timing, and accumulation (i.e., the number of specific types of adversities the child reported being exposed to).MethodsOur analytic sample comprised 9582 adolescents from the National Comorbidity Survey Replication Adolescent Supplement (NCS-A), a nationally representative population-based sample. We examined the association between 18 different types of retrospectively reported adversities (capturing interpersonal violence, accidents and injuries, social network or witnessing events, and other adverse events) and risk of self-reported past-year insomnia. We also examined whether the age at first exposure to adversity was associated with the risk of insomnia, and whether exposure to a greater number of different types of adversities (ie, accumulation) conferred an elevated risk of insomnia. In addition, we performed a sensitivity analysis excluding adolescents with a past-year diagnosis of major depression, dysthymia, post-traumatic stress disorder (PTSD), or generalized anxiety disorder.ResultsAlmost one-third of adolescents reported insomnia, with a higher prevalence among girls and those from racial/ethnic minority groups. Adolescents exposed to at least one childhood adversity of any type (59.41%) were more likely than their nonexposed peers to experience insomnia (across adversities, prevalence ratios (PRs) ranged from 1.31 to 1.89). Risk of insomnia differed based on the age at first exposure to adversity as well as the type of adversity. Adolescents exposed to a greater number of different types of adversities had a higher risk of insomnia compared to those experiencing fewer adversities. These results were similar, by and large, to those obtained after excluding adolescents with at least one of the four past-year psychiatric disorders.ConclusionsExposure to adversity confers an elevated risk of insomnia. This association varied by type, timing, and accumulation of exposure and did not appear to be driven by psychiatric disorders. Given the well-documented physical and mental health consequences of insomnia, such findings further support the need for practitioners to screen children for exposure to childhood adversity and insomnia symptoms.

Project description:Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder with early onset. ADHD is associated with significant morbidity and mortality, partly due to delayed diagnosis. Identification of children at high risk for developing ADHD could lead to earlier diagnosis and potentially change the negative trajectory of the illness for the better. Since early psychosocial adversity is considered to be a likely etiological risk factor for ADHD, markers of this construct may be useful for early identification of children at high risk. Therefore, we sought to investigate whether Rutter's indicators of adversity (low social class, severe marital discord, large family size, paternal criminality, maternal mental disorder, and placement in out-of-home care) assessed in infancy could serve as early predictors for the development of ADHD.Using data from the Danish nationwide population-based registers, we established a cohort consisting of all 994,407 children born in Denmark between January 1st 1993 and December 31st 2011 and extracted dichotomous values for the six Rutter's indicators of adversity at age 0-12 months (infancy) for each cohort member. The cohort members were followed from their second birthday and the association between the sum of Rutter's indicators of adversity (RIA-score) in infancy and subsequent development of ADHD was estimated by means of Cox regression. Also, the number needed to screen (NNS) to detect one case of ADHD based on the RIA-scores in infancy was calculated. During follow-up (9.6 million person-years), 15,857 males and 5,663 females from the cohort developed ADHD. For both males and females, there was a marked dose-response relationship between RIA-scores assessed in infancy and the risk for developing ADHD. The hazard ratios for ADHD were 11.0 (95%CI: 8.2-14.7) and 11.4 (95%CI: 7.1-18.3) respectively, for males and females with RIA-scores of 5-6, compared to males and females with RIA-scores of 0. Among males with RIA-scores of 5-6, 37.6% (95%CI: 27.0-50.7) had been diagnosed with ADHD prior to the age of 20, corresponding to a NNS of 3.0 (95%CI: 2.2-4.0).Rutter's indicators of adversity assessed in infancy strongly predicted ADHD. This knowledge may be important for early identification of ADHD.
