Post-traumatic stress disorder in a national sample of preadolescent children 9 to 10 years old: Prevalence, correlates, clinical sequelae, and treatment utilization.

Although posttraumatic stress disorder (PTSD) has been well characterized in adults, its epidemiology in children is unclear. The current study provides the first population-based examination of the prevalence of PTSD, sociodemographic and psychiatric correlates, clinical sequelae, and associations with psychiatric treatment in preadolescents 9-10 years old in the United States. Data from the Adolescent Brain and Cognitive Development (ABCD) Study (release 5.0) was analyzed. Participants (unweighted n = 11,875) were recruited from 21 sites across the United States. Current and lifetime PTSD prevalence were estimated, as was treatment use among children with PTSD. Sociodemographic, psychiatric correlates and sequelae of PTSD were analyzed using logistic regression, as was the association between PTSD and psychiatric treatment. After the application of propensity weights, lifetime prevalence of PTSD was 2.17%. Sexual minority status, being multiracial, having unmarried parents, and family economic insecurity were associated with greater odds of PTSD. Among psychiatric disorders, separation anxiety was most strongly associated with PTSD, although general comorbid psychopathology was associated with greater odds of PTSD. Prior history of PTSD predicted a new onset of other psychiatric disorders after PTSD remission. Nearly one in three children with lifetime PTSD did not receive psychiatric treatment, despite negative long-term outcomes of PTSD and significant psychiatric comorbidity. Even among preadolescents who experience full remission of PTSD, a significant risk for future psychiatric illness remains. Further, the current findings underscore the need for improved efforts to reduce unmet treatment needs among those with PTSD at this age.

Person-centered methods to advance developmental psychopathology.

Dante Cicchetti's remarkable contributions to the field of developmental psychopathology include the advancement of key principles such as the interplay of typical and atypical development, multifinality and equifinality, the dynamic processes of resilience, and the integration of multiple levels of analysis into developmental theories. In this paper we assert that person-centered data analytic methods are particularly well-suited to advancing these tenets of developmental psychopathology. We illustrate their utility with a brief novel empirical study focused on underlying patterns of childhood neuroendocrine regulation and prospective links with emerging adult functioning. Results indicate that a childhood neuroendocrine profile marked by high diurnal cortisol paired with low diurnal DHEA was uniquely associated with more adaptive functioning in emerging adulthood. We discuss these findings, and person-centered methods more broadly, within the future of developmental psychopathology.

Nonsuicidal Self-Injury in Preadolescents.

OBJECTIVES: There is a dearth of literature on the prevalence and predictors of nonsuicidal self-injury (NSSI) history and onset among preadolescent youth. This gap in the literature is significant given evidence suggesting that NSSI is a robust predictor of negative mental health outcomes, and that early onset NSSI may be associated with a more severe course of self-injurious thoughts and behaviors. This study aimed to evaluate sociodemographic characteristics, psychiatric disorders, and suicidal ideation (SI) in relation to NSSI onset and history in preadolescents. METHODS: Data were drawn from the Adolescent Brain and Cognitive Development (ABCD) study, which recruited a diverse sample of 11 875 youth aged 9 to 10 years. The primary outcome measures were lifetime history and recent onset of NSSI. Measures included sociodemographics and the K-SADS diagnostic interview assessing psychopathology and SI. RESULTS: Female sex and identifying as Black were associated with lower odds of lifetime NSSI. Identifying as a sexual minority, having unmarried parents, and a low family income were associated with higher odds of lifetime NSSI. Although depression was most predictive of NSSI history and onset, a range of internalizing and externalizing disorders, greater comorbidity, and SI also were predictive. CONCLUSIONS: Given that NSSI was associated with a range of mental health disorders and comorbidity, it may be best conceptualized as a transdiagnostic phenomenon. Findings highlight key sociodemographic and diagnostic factors that may help to direct screening efforts in preadolescents, particularly sexual minority status and depression.

Prevalence, predictors, and treatment of eating disorders in children: a national study.

BACKGROUND: Although the prevalence rates of preadolescent eating disorders (EDs) are on the rise, considerably less is known about the correlates and treatment of EDs in this age group. Clarifying the epidemiology of EDs in preadolescent children is a necessary first step to understand the nature and scope of this problem in this age group. METHODS: Analysis of data collected in the ABCD Study release 2.0.1. The ABCD cohort was a population-based sample that consisted of 11 721 children ages 9-10 years. Measures included reports of a lifetime and current mental disorders determined using a diagnostic interview for DSM-5 disorders, sociodemographic factors, and psychiatric treatment utilization. RESULTS: The lifetime prevalence of EDs was 0.95%. Being Black, multiracial, having unmarried parents, and family economic insecurity were significant predictors for developing an ED. Among psychiatric conditions, the major depressive disorder was most robustly associated with EDs in both cross-sectional and temporal analyses. Only 47.40% of children who had a lifetime ED received some type of psychiatric treatment. EDs were not a significant predictor of psychiatric treatment utilization after accounting for sex, sexual orientation, parent marital status, economic insecurity, and all other psychiatric diagnoses. CONCLUSIONS: Despite increasing prevalence rates of preadolescent EDs, the current findings suggest that the majority of children with these disorders remain untreated. Devoting increased attention and resources to reaching families of children with EDs with the least means for receiving care, and screening for EDs in children with depression, may be important steps for reducing this unmet need.

Individual differences in latent trait cortisol (LTC): Implications for the onset and course of future depressive symptoms.

Research suggests that various indicators of hypothalamic pituitary adrenal (HPA) axis activity prospectively predict depression, but few studies have evaluated whether trait indicators of HPA axis activity are related to depression. Further, no prior study has examined links between trait cortisol and psychopathology using a trait indicator that captures HPA axis activity over multiple time points. Here we examined whether we could construct an across-wave latent trait cortisol (LTC) factor using cortisol samples collected over 13 weeks, and whether the across-wave LTC prospectively predicted new depressive symptom onsets and symptom duration. Emerging adults (n = 85; M age = 19.37 years) provided salivary cortisol samples four times a day (waking, 30 min and 45 min post-waking and bedtime) over three 3-day measurement waves separated by 6 weeks. Diagnostic interviews at 3 timepoints (baseline, 1- and 2.5 years post-baseline) assessed lifetime and current depressive symptoms. Results indicated that the across-wave LTC predicted new onsets of depressive symptoms and longer symptom duration. Follow-up tests revealed that the link between the across-wave LTC and new onsets was not significant after adjusting for past depressive symptoms. These findings suggest that an indicator of individual differences in HPA axis regulation has implications for depressive symptom onsets and course.

Prevalence and correlates of suicidal ideation and suicide attempts in preadolescent children: A US population-based study.

The present study evaluated sociodemographic and diagnostic predictors of suicidal ideation and attempts in a nationally representative sample of preadolescent youth enrolled in the Adolescent Brain Cognitive Development Study. Rates and predictors of psychiatric treatment utilization among suicidal youth also were examined. Eleven thousand eight hundred and seventy-five 9- and 10-year-old children residing in the United States were assessed. Children and their parents/guardians provided reports of children's lifetime history of suicidal ideation, suicide attempts, and psychiatric disorders. Parents also reported on sociodemographic characteristics and mental health service utilization. Multivariate logistic regression analyses were employed to evaluate sociodemographic and diagnostic correlates of suicidal ideation, suicide attempts among youth with suicidal ideation, and treatment utilization among youth with suicidal ideation and suicide attempts. Lifetime prevalence rates were 14.33% for suicidal ideation and 1.26% for suicide attempts. Youth who identified as male, a sexual minority, or multiracial had greater odds of suicidal ideation, and sexual minority youth and youth with a low family income had greater odds of suicide attempts. Comorbid psychopathology was associated with higher odds of both suicidal ideation and suicide attempts. In youth, 34.59% who have suicidal ideation and 54.82% who had attempted suicide received psychiatric treatment. Treatment utilization among suicidal youth was lower among those who identified as female, Black, and Hispanic. Suicidal ideation and attempts among preadolescent children are concerningly high and targeted assessment and preventative efforts are needed, especially for males, racial, ethnic, and sexual minority youth, and those youth experiencing comorbidity.

Passive and active suicidal ideation among left-behind children in rural China: An evaluation of intrapersonal and interpersonal vulnerability and resilience.

OBJECTIVE: Although theoretical conceptualizations of suicide hold that passive and active suicidal ideation are etiologically distinct, existing research observing this distinction is modest, with most prior studies focusing exclusively on active ideation. Understanding processes associated with passive ideation is clinically important insofar as passive ideation may precede active ideation, and thus serve as an earlier intervention target prior to potential onset of suicidal behavior. We aimed to evaluate intrapersonal and interpersonal vulnerability and resilience factors for passive ideation and differentiating passive from active ideation. METHOD: Left-behind adolescents in rural China (n = 371) were assessed for passive and active ideation, depressive symptoms, rumination, grit, peer support, and peer victimization. RESULTS: Overall, 15.9% of the sample endorsed passive ideation without active ideation, and 17.8% endorsed active ideation. In multivariate analyses, rumination and grit differentiated left-behind children with passive ideation from those with no ideation. Depressive symptom severity predicted active ideation among adolescents with passive ideation. CONCLUSIONS: The current findings suggest that rumination and grit may characterize passive ideation. Although passive and active ideation may differ modestly in vulnerability and resilience factors, depressive symptoms may be important to monitor among those with passive ideation and have not yet experience active ideation.

Life stress, early maltreatment, and prospective associations with depression and anxiety in preadolescent children: A six-year, multi-wave study.

BACKGROUND: The relationship between life stress and depression and anxiety is well characterized in adolescents and adults. Further, research has shown that adolescents and adults with a history of childhood maltreatment are more likely to develop depression and anxiety after being exposed to stress than those without this history. However, the processes underlying risk for depression and anxiety in maltreated preadolescent children are unclear. The current study sought to identify these processes in at-risk preadolescents. METHODS: This study analyzed data from the Longitudinal Studies of Child Abuse and Neglect and evaluated interpersonal and non-interpersonal life stress as predictors of depression and anxiety specifically, and internalizing symptoms more generally, in a sample of children vulnerable or exposed to maltreatment (n = 1,049). Participants were assessed repeatedly over a six-year period of early-to-mid childhood. RESULTS: Interpersonal life stress prospectively predicted greater depression and anxiety, but not general internalizing symptoms after emotional and behavioral problems, as well as child's sex, family income and baseline maternal depressive symptoms, were covaried. Non-interpersonal life stress was not prospectively predictive of depression and anxiety or general internalizing symptoms. LIMITATIONS: The study was unable to identify specific types of interpersonal stress most relevant to risk for depression and anxiety in preadolescent children. CONCLUSIONS: These findings lend support for the importance of interpersonal stress when screening for risk for depression and anxiety among preadolescent children vulnerable or exposed to maltreatment. Early intervention to decrease the occurrence and impact of these stressors could have long-lasting impacts on this vulnerable population.
