RESUMEN

Research and theory suggest an important role of neuroendocrine function in emotional development, particularly under conditions of elevated stress. We provide empirical data to clarify associations between alpha-amylase (AA) and cortisol as well as test the differential linkages among AA, cortisol, and symptoms of anxiety, depression, and posttraumatic stress in children. Children recruited from a low-income elevated violence community (n = 100; mean age = 10, SD = 0.64; 79% Latino; 67% received free or reduced lunch) were assessed on diurnal levels of AA and cortisol along with assessments of anxiety, depression, and posttraumatic stress symptoms (PTSS). Elevated anxiety symptoms were associated with steeper linear slopes of AA with higher levels of AA in the morning but lower levels of AA in the evening. Depression was associated with differential cubic trajectories of AA when PTSSs were included in the model. Anxiety also predicted differential cubic diurnal trends in cortisol, such that greater anxiety symptoms were associated with relatively higher levels of cortisol in the evening. Again, depression symptoms when PTSS were included predicted diurnal cubic trends with elevated depression associated with lower awakening and midday cortisol that reversed to higher evening cortisol compared to youth with fewer self-reported depression symptoms.

RESUMEN

BACKGROUND: Interest in the effectiveness of mindfulness-based interventions such as yoga in primary schools has grown. Evidence shows promise, as youth who engage in yoga to promote mindfulness show improved coping skills, increased socio-emotional competence and prosocial skills, academic performance, attention span, and ability to deal with stress. OBJECTIVE: This study reports the results of a program evaluation of a universal health and wellness curriculum, Pure Power, designed to teach youth yoga techniques, mindfulness, and emotion regulation. METHODS: A non-randomized comparison design examined outcomes among participants from schools that completed the intervention with highest fidelity of implementation (n = 461) and from students in matched comparison schools (n = 420). Standard measures of coping, emotion regulation and emotion dysregulation, spelling, and math achievement were collected. RESULTS: Analyses suggest the youth in the intervention schools demonstrated relative improvement on measures of emotion regulation, spelling, and math. CONCLUSIONS: Challenges in implementation in real-life settings are vital to identify. The data provide some real-world evidence for the effectiveness of a universal health and wellness curriculum on emotion regulation and positive academic outcomes. Training school staff to deliver the intervention may foster implementation. Future research should test the effectiveness of who delivers the intervention; for example, teacher-delivered groups vs. other wellness personnel.

RESUMEN

Introduction: Treatment practice guidelines for posttraumatic stress disorder (PTSD) recommend both Eye Movement Desensitization and Reprocessing (EMDR) and Cognitive Behavior Therapy (CBT); however, implementation in practice setting remains challenging. Here we aim to foster implementation efforts for PTSD by identifying the relative use of the various components of empirically supported treatments by therapists and the characteristics that predict their use. Methods: Surveyed 346 therapists (84.07% female) of whom 272 participants (78.61%) were trained primarily in CBT and 135 participants (39.02%) were trained in primarily in EMDR. Assessed relative use of various EMDR and CBT components as well as several training and personality factors. Results: Psychoeducation about trauma was the most common element used. "Off label" use of components was also identified with application of EMDR techniques to other diagnoses. Findings also suggest underutilization of in vivo exposure techniques across therapists. EMDR therapists reported relatively high use of core EMDR techniques (i.e., greater use of EMDR core techniques). Big five personality factors, therapy efficacy, and anxiety were associated with differential component use. Discussion: Results identify trends in empirically supported component use and therapist characteristics that are associated with the use of various techniques for PTSD. The findings suggest implementation efforts could foster training in underused techniques, address barriers to their utilization and develop knowledge of effective packages of components.

RESUMEN

A developmental understanding of the expression of posttraumatic stress (PTS) symptoms following trauma in childhood requires identifying continuity and change in not just overall symptoms but in the individual symptoms as well. Such models of change also require understanding multiple dimensions of time. That is, longitudinal change-the passage of time-may have different effects on symptom expression depending on when in time an individual entered the study - such as what age they were when first assessed. This paper addresses these ideas with an overview of the developmental differences in the assessment of PTS from the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders, (DSM-5), longitudinal research on posttraumatic stress disorder (PTSD) symptoms, and providing synthesis within a symptom network perspective. We then provide an illustration of how individual PTSD symptoms change over time at different ages (elementary versus middle school) with a secondary analysis of data from a previously reported study (n = 191 youth, aged 8-15, assessed at two time points six months apart). The reanalysis of the data suggests both continuity and change in symptoms over time (i.e., some symptoms were more stable than other symptoms) with differences in symptom rates and their longitudinal change as a function of age (i.e., some symptoms more common or more stable in younger versus older or older versus younger). We close with avenues for future research aimed at better understanding symptom cascades over time and at different ages and potential implications for future iterations of assessment/classification systems.

RESUMEN

Introduction: Observational assessments are important for understanding a range of behaviors and emotions in the young child-caregiver relationship. This paper provides initial data on a multidimensional assessment for professionals who work with young children and their caregivers, the What to Look for in Relationships (WLR). The WLR was designed to assist providers in evaluating strengths and areas for improvement in five areas of young child-caregiver relationship dimensions. This paper reports on the development, interrater reliability, initial convergent and discriminant validity, and incremental utility of the scales. Methods: Data were collected from caregiver-child dyads, who participated in a semi-structured observational caregiver-child interaction session as part of a clinic evaluation for relationship-based therapeutic services for young children in child protection. Recorded interactions were coded using the WLR scales with 146 interactions coded by at least two independent observers for interrater reliability analyses. Results: The scales showed adequate internal consistency, good inter-rater reliability, strong convergent associations with a single dimension measure (i.e., the Parent-Infant Relationship Global Assessment Scale; PIR-GAS) and discriminated those in the clinical range from those with adaptive functioning on the PIR-GAS. Discussion: This study provides initial support for the usefulness of the WLR scales for assessing dimensions of caregiver-child relationships during early childhood that may be useful targets of intervention.

RESUMEN

Sleep patterns following a natural disaster are associated with mental health difficulties, but research in youth samples has been limited to subjective reports of sleep. Participants (N = 68, 8-17 years old) completed an assessment 6-9 months after Hurricane Harvey, which included subjective measures of sleep, chronotype, hurricane-related post-traumatic stress symptoms, and one week of actigraphy. Prior to the hurricane, parents provided reports on emotional symptoms. Controlling for age, sex, socioeconomic status, participation time, and pre-hurricane emotional symptoms, subjective sleep disturbances and an eveningness chronotype were associated with greater post-traumatic stress, with the strongest effects observed for re-experiencing, negative cognitions/mood, and arousal/reactivity symptoms. Later sleep timing as measured by actigraphy was associated with greater arousal/reactivity symptoms and shorter sleep duration was associated with greater avoidance symptoms. As extreme weather-related events are expected to become more frequent and severe, these findings contribute to models of youth risk and resilience.

RESUMEN

Since the COVID-19 outbreak, family members have spent more time together at home. This study introduces the concept of "family distancing"-the efforts to prevent the spread of the coronavirus to family members. We explore which demographic characteristics are associated with family distancing efforts and how the family distancing efforts are associated with family conflicts. Survey data were collected from adults (N = 324, M = 37 years; SD = 10.5 years; 65.1% female) in Korea. We found that gender, education, marital status, physical health status, and number of family members who live together were significantly associated with family distancing efforts. In addition, lower compliance with the request for family distancing was significantly associated with a higher degree of negative emotions (i.e., anger), which in turn was associated with more family conflict. The findings highlight the potential importance of family distancing efforts to maintain health but also their potential to increase family conflict.

RESUMEN

Anxiety and depression symptoms may leave children at risk for lower academic scores, though this unique linkage to academic achievement in underserved youth is less well established. This study aimed to examine how anxiety and depression are uniquely related to spelling and math achievement beyond attention and hyperactivity deficits in children in underserved schools. Children aged 8 to 11 (n = 1085, 47.3% female) from historically underserved groups (Hispanic 75.3%, American Indian 6.4%, Black 4.9%, and White 1.5%) from 13 schools across two public school districts in California participated in the assessment of emotional and behavioral health symptoms that included a spelling and math assessment. While there was no relationship between anxiety or hyperactivity on spelling and math scores, depression and attention problems were significantly negatively related to spelling and math scores. However, when entered simultaneously, evidence of suppressor effects emerged. Anxiety and hyperactivity both became positively predictive of math. Similarly, anxiety became positively predictive of spelling. Subsample analyses showed that these suppressor effects were only in females. The associations among anxiety, depression, attention, and hyperactivity with spelling and math achievement are complex, and when controlling for depression and attention, anxiety levels and hyperactivity may be motivating some level of achievement in these areas.

RESUMEN

BACKGROUND: Identifying neural activation patterns that predict youths' treatment response may aid in the development of imaging-based assessment of emotion dysregulation following trauma and foster tailored intervention. Changes in cortical hemodynamic activity measured with functional near-infrared spectroscopy (fNIRS) may provide a time and cost-effective option for such work. We examined youths' PTSD symptom change following treatment and tested if previously identified activation patterns would predict treatment response. METHODS: Youth (N = 73, mean age = 12.97, SD = 3.09 years) were randomly assigned to trauma-focused cognitive behavioral therapy (TF-CBT), cue-centered therapy (CCT), or treatment as usual (TAU). Parents and youth reported on youth's PTSD symptoms at pre-intervention, post-intervention, and follow-up. Neuroimaging data (N = 31) assessed at pre-intervention were obtained while youth engaged in an emotion expression task. Treatment response slopes were calculated for youth's PTSD symptoms. RESULTS: Overall, PTSD symptoms decreased from pre-intervention through follow-up across conditions, with some evidence of relative benefit of TF-CBT and CCT over TAU but significant individual variation in treatment response. Cortical activation patterns were correlated with PTSD symptom improvement slopes (r = 0.53). In particular, cortical responses to fearful and neutral facial stimuli in six fNIRS channels in the bilateral dlPFC were important predictors of PTSD symptom improvement. CONCLUSIONS: The use of fNIRS provides a method of monitoring and assessing cortical activation patterns in a relatively inexpensive and portable manner. Associations between functional activation and youths' PTSD symptoms improvement may be a promising avenue for understanding emotion dysregulation in clinical populations.

RESUMEN

Functional near-infrared spectroscopy (fNIRS) is a non-invasive neuroimaging technique with the potential to enable the assessment of posttraumatic stress disorder (PTSD) brain biomarkers in an affordable and portable manner. Consistent with biological models of PTSD, functional magnetic resonance imaging (fMRI) and fNIRS studies of adults with trauma exposure and PTSD symptoms suggest increased activation in the dorsolateral prefrontal cortex (dlPFC) and ventrolateral PFC (vlPFC) in response to negative emotion stimuli. We tested this theory with fNIRS assessment among youth exposed to traumatic stress and experiencing PTSD symptoms (PTSS). A portable fNIRS system collected hemodynamic responses from (N = 57) youth with PTSS when engaging in a classic emotion expression task that included fearful and neutral faces stimuli. The General Linear Model was applied to identify cortical activations associated with the facial stimuli. Subsequently, a prediction model was established via a Support Vector Regression to determine whether PTSS severity could be predicted based on fNIRS-derived cortical response measures and individual demographic information. Results were consistent with findings from adult fMRI and fNIRS studies of PTSS showing increased activation in the dlPFC and vlPFC in response to negative emotion stimuli. Subsequent prediction analysis revealed ten features (i.e., cortical responses from eight frontocortical fNIRS channels, age and sex) strongly correlated with PTSS severity (r = 0.65, p < .001). Our findings suggest the potential utility of fNIRS as a portable tool for the detection of putative PTSS brain biomarkers.

RESUMEN

Anxiety control beliefs (i.e., beliefs regarding one's ability to cope with external, fear-inducing threats and internal reactions to those perceived threats) have been found to negatively predict anxiety symptoms in children and adults and to be modifiable by cognitive-behavioral therapy for anxiety disorders. The current study examines whether changes in anxiety control beliefs were seen following a brief, intensive treatment for specific phobias, and whether those changes were associated with improvements in the targeted phobia and comorbid anxiety disorder symptoms. Participants were 135 children and adolescents (M age = 9.01 years, 49% male) who received one-session treatment (OST) with or without parental involvement for their primary specific phobia. Results indicated that self-reported anxiety control beliefs significantly increased following treatment and that these increases significantly predicted reductions in specific phobia severity and symptoms of comorbid anxiety disorders 6 months and 1 year following treatment. Findings illustrate that involvement in a single 3-hour OST was associated with changes in anxiety control beliefs and demonstrate the potential importance of targeting control beliefs in pediatric anxiety treatment.

RESUMEN

BACKGROUND: The development of reasoning as to the potential negative consequences of emotional sensations is a critical aspect of emotion knowledge and central to cognitive risk for anxiety disorders. The purpose of this paper is to explore the reasoning children and adolescents give for negative interpretations of anxiety sensations, testing a priori hypotheses quantitatively and exploring the content of the reasons qualitatively. METHODS: This study used a cross sectional design with interviews as well as cognitive and emotional assessments in a sample of 227 youth aged 6-17 years. Coding schemes to assess the logical validity, affective valence, and qualitative reasons that youth give to evaluate anxiety sensations and anxiety situations were developed. RESULTS: Findings indicated diverse reasoning was used and responses could be reliably coded with developmental differences across age, cognitive, and verbal development. The logical sophistication of the reasoning used by youth increased across age in a non-linear manner and linearly with cognitive and verbal abilities. Child anxiety sensitivity and internalizing symptom levels moderated the main effect of age. CONCLUSIONS: The results add to the existing understanding of emotional development and are consistent with the idea that the process of cognitive-emotional understanding is not a simple linear one because various domains may show differential development.

RESUMEN

Imaging methods have elucidated several neurobiological correlates of traumatic and adverse experiences in childhood. This knowledge base may foster the development of programs and policies that aim to build resilience and adaptation in children and youth facing adversity. Translation of this research requires both effective and accurate communication of the science. This review begins with a discussion of integrating the language used to describe and identify childhood adversity and their outcomes to clarify the translation of neurodevelopmental findings. An integrative term, Traumatic and Adverse Childhood Experiences (TRACEs+) is proposed, alongside a revised adverse childhood experiences (ACEs) pyramid that emphasizes that a diversity of adverse experiences may lead to a common outcome and that a diversity of outcomes may result from a common adverse experience. This term facilitates linkages between the ACEs literature and the emerging neurodevelopmental knowledge surrounding the effect of traumatic adverse childhood experiences on youth in terms of the knowns and unknowns about neural connectivity in youth samples. How neuroscience findings may lead directly or indirectly to specific techniques or targets for intervention and the reciprocal nature of these relationships is addressed. Potential implications of the neuroscience for policy and intervention at multiple levels are illustrated using existing policy programs that may be informed by (and inform) neuroscience. The need for transdisciplinary models to continue to move the science to action closes the article. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

RESUMEN

BACKGROUND: There is evidence that the amygdala undergoes extensive development. The exact nature of this change remains less clear, with evidence suggesting linear, curvilinear, and null effects. The aim of this study was the identification of a normative reference of left and right amygdala development by parceling variance into separate effects of age and longitudinal growth. METHODS: Data came from the National Institutes of Health MRI Study of Normal Brain Development. Participants in this sample were 54% female and ranged in age from 5 to 18 years (mean = 11.37 years) at study entry. RESULTS: As predicted, the age at initial scan moderated the slope of both left and right amygdala volumes, demonstrating that the nature of longitudinal growth varies across age (i.e., steeper slopes observed among those first scanned at an early age). Follow-up analysis showed that the positive longitudinal growth slope becomes nonsignificant at 13.1 years of age for the left amygdala and at 14.5 years for the right amygdala, suggesting that growth of the left amygdala peaks earlier than growth of the right amygdala. CONCLUSIONS: Findings suggest that rapid increases in volumes at early ages decline as youths enter adolescence and may turn to minor declines in volume during late adolescence or early adulthood.

RESUMEN

This commentary on the Journal of Traumatic Stress special issue on network analysis explores the network perspective on posttraumatic stress disorder (PTSD), emphasizing the advances in research made in this collection of articles. The commentary is organized around the following themes related to actualizing the perspective's methodological, assessment, and intervention potential and the potential shift in the theoretical underpinnings of mental disorders that networks models imply. First, extant data using network analysis suggest that reactions to traumatic stress are more complicated than once thought but that this complexity does not mean efficient, relatively simple heuristics to aid assessment and intervention do not exist. Attention to methodological issues in symptom assessment may help move this aspect of the research forward. Second, the extant research is largely correlational and has not yet established causal linkages, although temporal associations underlying network models are being identified. Prospective and intervention studies employing network analysis are critical. Third, the network perspective of PTSD symptoms may advance research on the mechanisms of risk and resilience (e.g., neurodevelopmental, cognitive behavioral, emotional, and social models) by helping link symptoms to theoretical causal processes. A developmental framework that views the effect of traumatic stress in terms of temporal cascades of reactions with both negative and potentially positive cognitive, behavioral, social, and emotional outcomes fits the network analysis model. Fourth, network models call into question some of the fundamental assumptions underlying the conceptualization of mental disorders, leaving several ontological questions and implications currently unanswered; research examining the implications of the new assumptions is needed.

RESUMEN

This study examined differences in generalized and social anxiety symptoms across two age groups of children with autism spectrum disorder (ASD) while accounting for overall anxiety level, gender, and intellectual functioning. Older children (12-18 years) expressed more overall and social anxiety symptoms than younger children (6-11 years), and social anxiety symptoms were predominant in the older group. Younger children expressed more generalized anxiety symptoms than the older youth, and there was a trend for generalized anxiety symptoms to be more dominant in the younger group. Findings are consistent with theory of differential expression of specific anxiety symptoms across different ages seen with typically developing children, yet social evaluative concerns may be even stronger for adolescents with ASD.

RESUMEN

There is strong evidence for the efficacy of empirically supported treatments (ESTs) for posttraumatic stress disorder (PTSD). However, treatment non-completion remains a considerable problem. Of concern with a high dropout rate is that Holmes et al. (2019) found that clients who attended more sessions improved at a greater rate and clients who completed all 12 sessions had the best outcomes. In addition to dropping out of treatment, there are a number of issues related to getting effective intervention to those exposed to traumatic stress. This commentary will discuss dosage and early treatment responders, delivery and packaging, and the need to go beyond diagnosis to build from the findings of Holmes et al. to foster the delivery of effective treatment.

RESUMEN

The apparent efficacy of d-cycloserine (DCS) for enhancing exposure treatment for anxiety disorders appears to have declined over the past 14 years. We examined whether variations in how DCS has been administered can account for this "declining effect". We also investigated the association between DCS administration characteristics and treatment outcome to find optimal dosing parameters. We conducted a secondary analysis of individual participant data obtained from 1047 participants in 21 studies testing the efficacy of DCS-augmented exposure treatments. Different outcome measures in different studies were harmonized to a 0-100 scale. Intent-to-treat analyses showed that, in participants randomized to DCS augmentation (n = 523), fewer DCS doses, later timing of DCS dose, and lower baseline severity appear to account for this decline effect. More DCS doses were related to better outcomes, but this advantage leveled-off at nine doses. Administering DCS more than 60 minutes before exposures was also related to better outcomes. These predictors were not significant in the placebo arm (n = 521). Results suggested that optimal DCS administration could increase pre-to-follow-up DCS effect size by 50%. In conclusion, the apparent declining effectiveness of DCS over time may be accounted for by how it has been administered. Optimal DCS administration may substantially improve outcomes. Registration: The analysis plan for this manuscript was registered on Open Science Framework (https://osf.io/c39p8/).
