Three-variable systems: An integrative moderation and mediation framework for developmental psychopathology.

In this article, we consider an often overlooked model that combines mediation and moderation to explain how a third variable can relate to a risk factor-psychopathology relationship. We refer to it as moderation and mediation in a three-variable system. We describe how this model is relevant to studying vulnerability factors and how it may advance developmental psychopathology research. To illustrate the value of this approach, we provide several examples where this model may be applicable, such as the relationships among parental externalizing pathology, harsh parenting, and offspring psychopathology as well as between neuroticism, stressful life events, and depression. We discuss possible reasons why this model has not gained traction and attempt to clarify and dispel those concerns. We provide guidance and recommendations for when to consider this model for a given data set and point toward existing resources for testing this model that have been developed by statisticians and other methodologists. Lastly, we describe important caveats, limitations, and considerations for making this approach most useful for developmental research. Overall, our goal in presenting this information to developmental psychopathology researchers is to encourage testing moderation and mediation in a three-variable system with the aim of advancing analytic strategies for studying vulnerability factors.

Pandemic-Related Experiences and Stress Among Children's Hospital Staff Predict Psychosocial Risk.

GOAL: COVID-19 has imposed unique challenges for healthcare workers who have faced increased risk of exposure to the virus, heightened work demands, and disruptions in work-life balance. For some healthcare workers, these challenges may have contributed to increased stress, burnout, and psychosocial impairment, including symptoms of depression and anxiety. The current study addresses a knowledge gap of associations between pandemic-related experiences and psychosocial risk among medical and nonmedical pediatric healthcare staff. METHODS: A sample of 369 staff (90% female) employed at an acute care, freestanding pediatric hospital in Connecticut completed an online survey. The survey assessed specific pandemic-related experiences and perceived impact with the Epidemic-Pandemic Impacts Inventory, and depression and anxiety risk with the 2-item Patient Health Questionnaire depression screen and 2-item Generalized Anxiety Disorder screen, respectively. Enrollment and survey completion occurred over a 6-week period during the pandemic (summer 2020). PRINCIPAL FINDINGS: High rates of adverse pandemic-related experiences included workplace experiences (e.g., inadequate support, interpersonal difficulties), home life (e.g., childcare difficulties, partner conflict), and experiences reflecting social isolation and quarantine, child and adult mental health difficulties, increased alcohol or substance use, and unhealthy lifestyle behaviors. Medical relative to nonmedical staff reported significantly more adverse and fewer positive experiences, and a significantly higher perceived negative impact of workplace experiences. A positive screen for depression or anxiety was significantly predicted by cumulative adverse workplace experiences (OR = 1.15), changes in emotional/physical health (OR = 1.35), and perceived negative impact of workplace experiences (OR = 1.32). APPLICATIONS TO PRACTICE: The present study joins recent reports of increased adverse experiences and psychosocial outcomes among healthcare workers during the COVID-19 pandemic. Findings underscore the need for pediatric hospitals to innovate ways to reduce burden and connect staff to mental health services during similar public health crises. Such services might include (1) assisting healthcare staff to navigate disruptions in their home and social lives as a result of new challenges faced at work, (2) adapting the hospital environment and culture to mitigate stress experienced by staff because of these challenges, and (3) bolstering mental health screening and services to address exacerbated or emerging mental health symptoms, such as depression and anxiety.

Neurophysiological patterns associated with blunted emotional face processing and withdrawal tendencies in young children exposed to intimate partner violence.

Studies linking child maltreatment to abnormal neurophysiological responses to emotional stimuli and mental health impairment have not specifically explored these patterns in young children exposed to intimate partner violence (IPV). The present study examined two neurophysiological indicators, resting-state electroencephalography and an emotion event-related potential (ERP) in 21 IPV exposed and 30 nonexposed children ages 4-6 years recruited from the community and domestic violence shelters. Frontal alpha asymmetry (FAA) was assessed while at rest. FAA is often associated with avoidant/withdrawn behavior and increased risk of IPV-related mental health conditions (e.g., depression). Additionally, the late positive potential (LPP) ERP component, reflecting motivated attention, was acquired in the context of an age-appropriate affective oddball paradigm with low probability animal pictures as targets and human facial expressions (angry, happy, neutral) as distracters. Results demonstrated that IPV-exposed children, compared with nonexposed children, exhibited lower left FAA during resting state and reduced LPPs to oddball targets and affective faces relative to neutral faces in the oddball task. Together, these results suggest neural patterns associated with a blunted response to emotional stimuli and withdrawal tendencies, respectively, in young children exposed to IPV. Implications for emotional socialization in this vulnerable population are discussed.

An Item Response Theory examination of the original and short forms of the Difficulties in Emotion Regulation Scale (DERS) in pregnant women.

OBJECTIVES: Emotion dysregulation during pregnancy may impede women's capacity to navigate increased stressors during this period and may elevate risk for psychosocial impairment, especially for socioeconomically disadvantaged or racially marginalized women. Valid and efficient assessment of emotion dysregulation is needed. METHODS: We used Item Response Theory (IRT) to examine the Difficulties in Emotion Regulation Scale (DERS) in 248 low income, primarily Latina/x pregnant women, to compare the short forms relative to the full DERS. RESULTS: IRT indicated that the short forms exhibited modest reliability, but also indicated a substantial decrease in information (i.e., reliability) for the short forms compared with the full DERS. IRT indicated that the DERS-16 appeared more reliable (conserve more information) relative to the other short forms, the DERS-SF and DERS-18. CONCLUSION: Findings suggest that clinicians and researchers use the full DERS when time permits and the DERS-16 when needing a briefer version.

Association of Adverse Family Experiences with School Engagement and Performance in US Adolescents: Do Behavioral Health Conditions Mediate the Relationship?

To examine the prevalence of adverse family experiences (AFEs), their association with poor school engagement and performance, and whether behavioral health conditions mediate the association among US adolescents. We conducted a cross-sectional analysis of data from adolescents aged 12-17 years from the 2016-2018 National Survey of Children's Health (n = 41,648 unweighted). We first estimated the prevalence of AFEs, investigated the association of AFEs with school engagement and performance, and whether behavioral health conditions mediate such relationships, using multivariable-adjusted Poisson regression models. A mediation analysis was used and covariates included socio-demographic characteristics and co-morbid medical conditions. A total of 52.9% of US adolescents (nationally representative of 12.9 million adolescents nationwide) reported experiencing at least one form of AFE, the most common of which included parental divorce/separation (33.1%), economic hardship (22.0%) and living with a person with substance misuse problems (11.5%). Adolescents with ≥4 AFEs had poorer outcomes in school engagement and performance (p < 0.001 each) when compared to those with no AFEs. Behavioral health conditions (e.g., anxiety, depression, and conduct problems) partially mediated these relationships (p < 0.01 each). The indirect effect of behavioral health conditions accounted for 20.4% of the total effect in the association between AFEs and school performance (p < 0.001). AFEs are common among US adolescents, and cumulative AFEs are associated with behavioral health conditions, which may in turn reduce school engagement and performance. While reducing AFEs is important in children and adolescents, addressing potentially resultant behavioral health conditions is equally important in improving school engagement and performance.

A multi-method and multi-informant approach to assessing post-traumatic stress disorder (PTSD) in children.

Trauma exposure is highly prevalent among children globally, and is associated with elevated rates of PTSD. The goal of this study was to systematically evaluate the effects of multiple informants and multiple screening measures on the identification of specific PTSD symptoms and rates of PTSD diagnoses. Participants in this study included 350 maltreated children from two cohorts, one recruited from Connecticut (n = 130), and the other from Vermont (n = 220). Both cohorts completed the Screen for Child Anxiety-Related Emotional Disorders (SCARED) before a PTSD self-report measure. The KSADS psychiatric interview was also completed with the Connecticut cohort, with best-estimate ratings generated using parent and child interview, child self-report, and teacher questionnaire data. In addition to the SCARED and PTSD self-report scale, parents of the Vermont cohort completed the Child Behavioural Checklist. Significant differences emerged between parent and child report of sleep, nightmares, concentration, and irritability problems, suggesting the need for multiple informants in PTSD screening. Children also under-reported nightmares when asked in the context of a trauma-specific screening tool. As child trauma is associated with a broad range of psychiatric sequelae, comprehensive assessment using both general symptomatology and trauma-specific measures is recommended, since children often shut down when completing trauma measures.

Factor Structure, Reliability, and Validity of the Daily Self-Report Measure for Trauma-Related Sequelae (DSR-TRS).

The structure and psychometrics of daily self-report measures have only rarely been empirically tested. We developed the Daily Self-Report of Trauma-Related Sequelae (DSR-TRS), comprised of items assessing, in the past day: (1) posttraumatic stress disorder (PTSD) symptoms: (2) symptoms of affective-, behavioral-, relational-, somatic-, dissociative-, and self-dysregulation; and (3) stressors, mood, coping strategies, and drug and alcohol use. Psychometric analyses were conducted with data from 141 women who participated in a randomized clinical trial of two present-centered therapies for PTSD or a wait-list condition and completed at least one DSR-TRS during two 30-day periods at baseline and posttreatment/wait-list. Five DSR-TRS subscales were created based on a series of exploratory, confirmatory, and multilevel factor analyses: Positive Affect, Negative Affect, Self-Regulation, Dysregulation, and PTSD symptoms. DSR-TRS subscales had acceptable within-person and between-person reliability. Convergent and discriminant validity were supported at baseline and posttest in relation to questionnaire and interview assessment measures. Implications for research on daily self-report measures such as the DSR-TRS with trauma survivors are discussed.

Randomized clinical trial pilot study of prolonged exposure versus present centred affect regulation therapy for PTSD and anger problems with male military combat veterans.

A randomized controlled trial pilot study (www.ClinicalTrials.org; NCT01228539) with N = 31 U.S. male military recent combat veterans with PTSD and severe anger problems was conducted comparing 10-session individual therapy versions of Trauma Affect Regulation: Guide for Education and Therapy (TARGET) versus prolonged exposure (PE). TARGET had fewer drop-outs than PE (i.e., 29% vs. 64%). At post-test, improvements were found for both interventions in increased emotion regulation and hope, and reduced PTSD symptoms, hostility, experiential avoidance, and mental health problems. At a four-month follow-up, comparable proportions (approximately 40%) of recipients in each therapy maintained clinically significant gains. Self-rated expectancy of therapeutic outcome and working alliance was comparable for both PE and TARGET early in therapy, at mid-treatment, and at the end of treatment. While preliminary, these results suggest that TARGET may be a viable therapeutic option for male military veterans with PTSD and anger problems.

Development and Preliminary Feasibility Testing of a Decision Support Tool for Childhood Anxiety Treatment.

In this practical application, we describe the steps to build a decision-support tool using GeNIe 2.1 software. The method incorporates principles of decision analyses and allows for a systematic strategy to balance treatment efficacy data with patient preferences. We illustrate the utility for helping clinicians and patients choose between two or more efficacious treatment options (CBT, medication, or their combination). Preliminary pilot data from families (n = 5) seeking services at a specialty clinic for childhood anxiety disorders support the usability of the tool and high patient satisfaction. We use case examples and sample graphical output to illustrate how the decision-support system can be used to integrate data on, 1) baseline symptom severity 2) the relative effectiveness of two or more treatment options, and 3) patient preferences and values, to arrive at a personalized treatment recommendation. The decision-support tool enabled child and parent preferences to be explicitly stated and facilitated discussions about how best to incorporate their preferences into an evidenced-based treatment strategy.

Emotion Regulation Enhancement of Cognitive Behavior Therapy for College Student Problem Drinkers: A Pilot Randomized Controlled Trial.

This pilot randomized clinical trial tested an emotion regulation enhancement to Cognitive Behavior Therapy (CBT) with 29 college student problem drinkers with histories of complex trauma and current clinically significant traumatic stress symptoms. Participants received eight face-to-face sessions of manualized internet-supported CBT for problem drinking with or without trauma-focused emotion regulation skills (Trauma Affect Regulation: Guide for Education and Therapy, TARGET). Both interventions were associated with sustained (at one-month follow-up) reductions in self-reported drinking frequency, drinking related impairment, and heavy drinking in the past week, as well as post-traumatic stress disorder (PTSD) and complex PTSD symptoms, and improvement in self-reported emotion regulation. The enhanced intervention was associated with significantly greater sustained reductions in complex PTSD symptoms and resulted in medium/large effect size reductions in days of alcohol use (versus small effects by CBT). Emotion regulation enhancement of CBT for college student problem drinkers with interpersonal trauma histories warrants further investigation.

The Family Socialization Interview-Revised (FSI-R): a Comprehensive Assessment of Parental Disciplinary Behaviors.

Elucidating the complex mechanisms by which harsh parenting increases risk of child psychopathology is key to targeted prevention. This requires nuanced methods that capture the varied perceptions and experiences of diverse families. The Family Socialization Interview-Revised (FSI-R), adapted from an interview developed by Dodge et al. (Child Development, 65, 649-665, 1994), is a comprehensive, semi-structured interview for characterizing methods of parental discipline used with young children. The FSI-R coding system systematically rates parenting style, usual discipline techniques, and most intense physical and psychological discipline based on rater judgment across two eras: (1) birth to the previous year, and (2) the previous year to present. The current study examined the psychometric properties of the FSI-R in a diverse, high-risk community sample of 386 mothers and their children, ages 3 to 6 years. Interrater reliability was good to excellent for codes capturing physically and psychologically harsh parenting, and restrictive/punitive parenting styles. Findings supported the FSI-R's convergent and incremental validity. Importantly, the FSI-R demonstrated incremental utility, explaining unique variance in children's externalizing and internalizing symptoms beyond that explained by traditional surveys and observed parenting. The FSI-R appeared particularly promising for capturing risk associated with young children's depressive symptoms, as these were generally not significantly associated with other measures of harsh parenting. Overall, findings support the added value of the FSI-R within a multi-method assessment of disciplinary practices across early child development. Future implications for prevention are discussed.

UNPACKING THE BURDEN OF CARE FOR INFANTS IN THE NICU.

Infants who begin early life in the medicalized environment of the neonatal intensive care unit (NICU) experience disruption to numerous fundamental expectancies. In the NICU, infants are exposed to chronic, extreme stressors that include painful medical procedures and parental separation. Due to their preverbal stage of development, infants are unable to fully express these experiences, and linking these experiences to long-term outcomes has been difficult. This clinical article proposes the terminology Infant Medical Trauma in the NICU (IMTN) to describe the infant experience. Following a discussion of the NICU as an adverse childhood event, the article has three sections: (a) the unique and critical factors that define the newborn period, (b) a review of the IMTN conceptual model, and (c) recommendations for supportive neuroprotective strategies to moderate the intensity of adverse NICU infant experiences.

Examining Patterns of Exposure to Family Violence in Preschool Children: A Latent Class Approach.

Young children can experience violence directly or indirectly in the home, with some children exposed to multiple forms of violence. These polyvictims often experience violence that is severe, chronic, and multifaceted. The current study used latent class analysis to identify and examine the pattern of profiles of exposure to family violence (i.e., violence directed towards the child and between caregivers) among a sample of 474 children ages 3-6 year who were drawn from the Multidimensional Assessment of Preschoolers Study (Wakschlag et al., 2014). The data yielded 3 classes: a polyvictimized class (n = 72; 15.2%) with high probability of exposure to all forms of violence, a harsh parenting class (n = 235; 49.5%), distinguished mainly by child-directed physical discipline in the absence of more severe forms of violence, and a low-exposure class (n = 167; 35.2%). Classes were differentiated by contextual factors, maternal characteristics, and mother-reported and observational indicators of parenting and child functioning with most effect sizes between medium and large. These findings add to emerging evidence linking polyvictimization to impaired caregiving and adverse psychological outcomes for children and offer important insight for prevention and intervention for this vulnerable population.

Infant Medical Trauma in the Neonatal Intensive Care Unit (IMTN): A Proposed Concept for Science and Practice.

BACKGROUND: Trauma is an innately subjective experience ensuing from a deeply distressing event. Research has demonstrated that while the environment of the neonatal intensive care unit (NICU) is capable of providing extraordinary lifesaving measures following birth, the experience may be disruptive to several key aspects of early development, placing infants at risk for adverse behavioral, cognitive, and emotional outcomes. PURPOSE: This article provides rationale for the concept of Infant Medical Trauma in the NICU (IMTN) as a means of describing this unique stress experience. A triad of cumulative early life NICU experiences (stress, parental separation, and pain) is proposed to influence an infant's swinging neurodevelopmental pendulum amid the potential outcomes of risk and resilience. IMPLICATIONS FOR PRACTICE AND RESEARCH: Creating language that describes the infant experience brings meaning and calls caregivers and parents to action to consider strategies that may improve long-term health. Actively seeking opportunities to decrease the allostatic load of at-risk infants may support an infant's pendulum to swing toward a path of resilience, thereby moderating his or her early life adverse experience.

Trauma-focused treatment in a state system of care: is it worth the cost?

The efficacy of Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) in treating child traumatic stress inspires nationwide dissemination, yet widespread adoption by state systems of care is lagging. A significant barrier is the cost of implementation and maintenance of evidence-based services. Thus, the current study examined the annual costs of mental health services accrued for 90 publiclyinsured, trauma-exposed children from the time they began participation in a TF-CBT implementation project to 1 year after their admission. These costs were compared to those accrued over that same time period by 90 trauma-exposed control children that were matched by demographics and prior mental health services utilization using a propensity score matching algorithm and provided outpatient treatment as usual. Results indicated that (a) 27.5 % of the total cost was attributed to high-end services utilized by only 1.67 % of children; (b) two times more money was spent on low-end mental health services received by the TF-CBT group than the control group, and (c) five times more money was spent on high-end mental health services received by the control group than the TF-CBT group in that year. These data suggest that providing evidence-based trauma-focused outpatient treatment to children with trauma-related problems may offset the eventual need for services that are more restrictive and costly.

Caregiver Report of Children's Exposure to Adverse Life Events: Concordance Between Questionnaire and Interview Approaches.

Assessment practices for measuring adverse life events (ALEs) are often characterized by considerable variability, which is associated with inconsistency and reproducibility issues when conducting research on children with ALE exposure. One aspect of assessment variability for caregiver report of children's ALE history that has received minimal attention is assessment format. To address this issue, the current study evaluated concordance between two main ALE assessment formats: interviews and questionnaires. This involved examining overall endorsement of ALEs and concordance among multiple characteristics of ALE exposure, including type, polyvictimization, frequency, severity, and age of onset. Fifty-eight caregivers (Mage = 33.72; 60% Black; 55% below the federal poverty line) of preschool and school-age children were administered an ALE assessment in both a questionnaire and interview format across two sessions. The sum scores and concordance rates between format responses were compared based on ALE type, polyvictimization, frequency, severity, and age of onset of exposure. Results indicated that most total or sum scores were similar between formats, with the exception of ALE severity scores. However, there was most often low-to-moderate concordance across the 50 types of ALEs examined in the current study, suggesting that a different constellation of events comprised each sum or total score. This was also the case across all characteristics of the ALEs and most notably for the severity of ALE. Based on these findings, the format of assessment may be associated with inconsistent reporting of children's ALE exposure across multiple characteristics of ALE. Researchers may need to utilize multiple types of ALE assessments when relying on caregiver report of a child's ALEs.

The Moderating and Mediating Role of Responsive Parenting Behavior in Explaining the Link between Intimate Partner Violence and Posttraumatic Stress Symptoms in Young Children.

Responsive parenting serves an influential role in explaining the link between children's exposure to intimate partner violence (IPV) and children's mental health impairment, but how this occurs is not well elucidated. In some cases, researchers examine parenting as a mediator to explain how IPV leads to maladaptive outcomes (i.e., IPV negatively impacts one's capacity for responsive parenting, which in turn impacts children), whereas others examine moderation in which either the absence of responsive parenting exacerbates adverse outcomes or increased responsive parenting buffers risk. Mediation addresses theoretical questions about how or why IPV leads to maladaptive outcomes, whereas moderation addresses who might be most impacted. However, responsive parenting has rarely, if ever, been tested as both a mediator and moderator of the link between IPV and posttraumatic stress symptoms (PTSS) within the same sample. The current study examined the mediating and moderating role of responsive parenting on physical IPV exposure and child PTSS in a longitudinal sample of 391 children ages 3 to 5 years (M = 4.74, SD = 0.89). Self-report measures of physical IPV exposure, parenting practices, and PTSS were completed by mothers. We found that responsive parenting significantly moderated and mediated the association between physical IPV exposure and child PTSS over time. Studies that include tests of both moderation and mediation are critical for advancing mechanistic insight into the role of parenting in the etiology of mental health impairment in children exposed to IPV.

Early life trauma exposure and stress sensitivity in young children.

OBJECTIVE: The current study replicates and extends work with adults that highlights the relationship between trauma exposure and distress in response to subsequent, nontraumatic life stressors. METHODS: The sample included 213 2-4-year-old children in which 64.3% had a history of potential trauma exposure. Children were categorized into 4 groups based on trauma history and current life stress. RESULTS: In a multivariate analysis of variance, trauma-exposed children with current life stressors had elevated internalizing and externalizing problems compared with trauma-exposed children without current stress and nontrauma-exposed children with and without current stressors. The trauma-exposed groups with or without current stressors did not differ on posttraumatic stress disorder symptom severity. Accounting for number of traumatic events did not change these results. CONCLUSIONS: These findings suggest that early life trauma exposure may sensitize young children and place them at risk for internalizing or externalizing problems when exposed to subsequent, nontraumatic life stressors.

Patterns of multiple victimization among maltreated children in Navy families.

The current study examined the cumulative risk associated with children's exposure to multiple types of parent-inflicted victimization. The sample was comprised of 195 children who were 7 to 17 years old (64.1% female and 48.2% non-White) at the time of referral to the United States Navy's Family Advocacy Program due to allegations of sexual abuse, physical abuse, or parental intimate partner violence. We conducted an exploratory latent class analysis to identify distinct subgroups of children based on lifetime victimization. We hypothesized that at least 2 classes or subgroups would be identified, with 1 characterized by greater victimization and poorer outcomes. Results indicated that 3 classes of children best fit the data: (a) high victimization across all 3 categories, (b) high rates of physical abuse and witnessing intimate partner violence, and (c) high rates of physical abuse only. Findings indicated that the high victimization class was at greatest risk for alcohol and substance use, delinquent behavior, and meeting criteria for posttraumatic stress disorder (PTSD) and/or depression 1 year later (odds ratio = 4.53). These findings highlight the serious mental health needs of a small but significantly high-risk portion of multiply victimized children entering the child welfare system.

Building a consumer base for trauma-focused cognitive behavioral therapy in a state system of care.

This paper documents the scope and limitations of an outreach effort to build a consumer base for Trauma-focused cognitive behavioral therapy in a state public mental health system for children. Three key aspects are discussed: the fostering of an informed referral network, the development of screening and identification services, and the engagement of families. Referral, screening and engagement are each examined against the backdrop of existing literature on implementation and dissemination. Each aspect of the implementation plan is described in detail-as are the barriers encountered and lessons learned during the course of execution. We provide several recommendations to assist other efforts to implement Evidence-Based Treatments into state systems of care.
