AIM/OBJECTIVE:This study examined the direct and indirect associations between childhood psychopathology symptoms, screen use, media multitasking and participation in non-digital recreation. METHODS:Psychopathology symptoms, media use, media multitasking, participation in sports, social clubs and reading/games were reported by 520 parents about their 3-11-year-old children. The data were analysed using structural equation modelling. RESULTS:There were bi-directional negative associations between sports participation and emotional problems (β = -.16, p < .001 and β = -.15, p < .001); ADHD symptoms were associated with reduced reading/games (β = -.14, p = .004). A bi-directional positive association was found between media use and conduct problems (β = .10, p = .015 and β = .14, p = .015). Increased media multitasking was indirectly associated with elevated symptoms of ADHD via a reduction in reading/games (β =.10, p = .026). However, there was no evidence that screen use mediated the associations between psychopathology symptoms and non-digital recreation. CONCLUSION/CONCLUSIONS:Depending on the specific psychological difficulties, children are either less likely to participate in non-digital recreation or are more likely to use screen media or multitask with media. Interventions for children, who experience emotional or behavioural difficulties, are needed to improve participation in non-digital recreation.

Environmental adversity increases child susceptibility to disrupted developmental outcomes, but the mechanisms by which adversity can shape development remain unclear. A translational cross-species approach was used to examine stress-mediated pathways by which poverty-related adversity can influence infant social development. Findings from a longitudinal sample of low-income mother-infant dyads indicated that infant cortisol (CORT) on its own did not mediate relations between early-life scarcity-adversity exposure and later infant behavior in a mother-child interaction task. However, maternal CORT through infant CORT served as a mediating pathway, even when controlling for parenting behavior. Findings using a rodent "scarcity-adversity" model indicated that pharmacologically blocking pup corticosterone (CORT, rodent equivalent to cortisol) in the presence of a stressed mother causally prevented social transmission of scarcity-adversity effects on pup social behavior. Furthermore, pharmacologically increasing pup CORT without the mother present was not sufficient to disrupt pup social behavior. Integration of our cross-species results suggests that elevated infant CORT may be necessary, but without elevated caregiver CORT, may not be sufficient in mediating the effects of environmental adversity on development. These findings underscore the importance of considering infant stress physiology in relation to the broader social context, including caregiver stress physiology, in research and interventional efforts.

The current study contributes to a sparse literature on moderators of Functional Family Therapy (FFT) by examining whether responsiveness to FFT, measured by a broad range of outcomes, varies by adolescent gender, age, and their interaction. This study was informed by 687 families (n, adolescents = 581; n, caregivers = 933) and utilized a pre-post comparison design. Fixed-effects regressions with gender, age, and their interaction included as explanatory variables were conducted to calculate the average change in youth mental health, callous-unemotional traits, academic outcomes, substance use, and family functioning. Moderation analyses revealed that according to parent report, girls had significantly greater improvements in peer problems and family functioning, and boys benefited more in increased liking of school. There were differential effects by age, such that older youth had less beneficial mental health outcomes and a smaller decrease in frequency of hash use. The gender by age interaction was significant for adolescents' report of mental health and family functioning outcomes, which suggests that girls benefit from FFT less than boys during early adolescence, but benefit more than boys in late adolescence. This finding adds to literature which has evidenced that family functioning is particularly important for girls by suggesting that FFT is important for improving older girls' mental health and family functioning in particular. The study's results expand the examination of outcomes of FFT to include academic outcomes, and provide insight into key factors that should be considered in addressing adolescent behavioral problems and family functioning.

Ethnic South Asian Americans (SAAs) have the highest relative risk of type 2 diabetes mellitus (T2DM) in the United States (US). Culturally tailored lifestyle interventions have the potential to promote South Asian diabetes prevention; however, the extent of their use and evaluation in US settings remains limited. This systematic review characterizes and evaluates outcomes of community-based lifestyle interventions targeted towards T2DM indicators among South Asians living in the US. A PRISMA-informed search of Pubmed, Embase, Cochrane, Web of Science, and clinical trial registry databases using key words pertaining to South Asians migrants and diabetes indicators (glucose and insulin outcomes) was conducted of community-based lifestyle interventions published up until October, 31 2019. Of the eight studies included in the final synthesis, four interventions focused on cultural and linguistic adaptations of past chronic disease prevention curricula using group-based modalities to deliver the intervention. Hemoglobin A1c (A1c) was the most common outcome indicator measured across the interventions. Three of the five studies observed improvements in indicators post-intervention. Based on these findings, this review recommends 1) greater exploration of community-based lifestyle interventions with high quality diabetes indicators (such as fasting blood glucose) in ethnic SAA communities, 2) expanding beyond traditional modalities of group-based lifestyle interventions and exploring the use of technology and interventions integrated with passive, active, and individualized components, and 3) development of research on diabetes prevention among second generation SAAs.

OBJECTIVE:Implementation of evidence-based treatments in funded trials is often supported by expert case consultation for clinicians; this may be financially and logistically difficult in clinical practice. Might less costly implementation support produce acceptable treatment fidelity and clinical outcomes? METHOD/METHODS:To find out, we trained 42 community clinicians from four community clinics in Modular Approach to Therapy for Children (MATCH), then randomly assigned them to receive multiple lower-cost implementation supports (LC) or expert MATCH consultation plus lower-cost supports (CLC). Clinically referred youths (N = 200; ages 7-15 years, M = 10.73; 53.5% male; 32.5% White, 27.5% Black, 24.0% Latinx, 1.0% Asian, 13.5% multiracial, 1.5% other) were randomly assigned to LC (n = 101) or CLC (n = 99) clinicians, and groups were compared on MATCH adherence and competence, as well as on multiple clinical outcomes using standardized measures (e.g., Child Behavior Checklist, Youth Self-Report) and idiographic problem ratings (Top Problems Assessment). RESULTS:Coding of therapy sessions revealed substantial therapist adherence to MATCH in both conditions, with significantly stronger adherence in CLC; however, LC and CLC did not differ significantly in MATCH competence. Trajectories of change on all outcome measures were steep, positive, and highly similar for LC and CLC youths, with no significant differences; a supplemental analysis of posttreatment outcomes also showed similar LC and CLC posttreatment scores, with most LC-CLC differences nonsignificant. CONCLUSIONS:The findings suggest that effective implementation of a complex intervention in clinical practice may be supported by procedures that are less costly and logistically challenging than expert consultation.

Pre-operative anxiety affects millions of pediatric surgery patients each year and can have both short and long-term adverse effects in the post-operative period. As a result, it is particularly important for healthcare providers and others involved in the child's care, such as the parents, to be aware of interventions that can be used to reduce the onset of pre-operative anxiety and, thus, the likelihood of negative post-operative changes. The purpose of this paper is to familiarize the reader with the issue of pre-operative anxiety through a review of the literature and analysis of case studies. First, the paper looks at the causes of pre-operative anxiety and its effect on the development of maladaptive behavioral, emotional, and physiological changes. It then discusses the ways pre-operative anxiety can be measured and current methods for reducing the post-operative adverse outcomes associated with it. After doing so, it proposes the need for additional research and the use of precision medicine by physicians.

During a sensitive period associated with attachment, the infant brain has unique circuitry that enables the specialized adaptive behaviors required for survival in infancy. This infant brain is not an immature version of the adult brain. Within the attachment relationship, the infant remains close (proximity seeking) to the caregiver for nurturing and survival needs, but the caregiver also provides the immature infant with the physiological regulation interaction needed before self-regulation matures. Here we provide examples from the human and animal literature that illustrate some of these regulatory functions during sensitive periods, recent advances demonstrating the supporting transient neural mechanisms, and how these systems go awry in the absence of species-expected caregiving.

Single-case experimental designs (SCEDs) involve obtaining repeated measures from one or a few participants before, during, and, sometimes, after treatment implementation. Because they are cost-, time-, and resource-efficient and can provide robust causal evidence for more large-scale research, SCEDs are gaining popularity in trauma treatment research. However, sophisticated techniques to analyze SCED data remain underutilized. Herein, we discuss the utility of SCED data for trauma research, provide recommendations for addressing challenges specific to SCED approaches, and introduce a tutorial for two Bayesian models-the Bayesian interrupted time-series (BITS) model and the Bayesian unknown change-point (BUCP) model-that can be used to analyze the typically small sample, autocorrelated, SCED data. Software codes are provided for the ease of guiding readers in estimating these models. Analyses of a dataset from a published article as well as a trauma-specific simulated dataset are used to illustrate the models and demonstrate the interpretation of the results. We further discuss the implications of using such small-sample data-analytic techniques for SCEDs specific to trauma research.

Background/UNASSIGNED:Post-COVID syndrome is increasingly recognized by the medical community but has not been studied exclusively in young adults. This preliminary report investigates the prevalence and features of protracted symptoms in non-hospitalized university students who experienced mild-to-moderate acute illness. Methods/UNASSIGNED:148 students completed an online study to earn research credit for class. Data from COVID-19 positive participants with symptoms ≥28 days (N=22) were compared to those who fully recovered (N=21) and those not diagnosed with COVID-19 (N=58). Results/UNASSIGNED:51% of participants who contracted COVID-19 (N=43) experienced symptoms ≥28 days and were classified as having post-COVID syndrome; all but one (96%) were female. During acute illness the post-COVID group, compared to those who fully recovered, experienced significantly more chest pain (64% vs 14%; P=.002), fatigue (86% vs 48%; P=.009), fever (82% vs 48%; P=.02), olfactory impairment (82% vs 52%; P=.04), headaches (32% vs 5%; P<.05), and diarrhea (32% vs 5%; P<.05). Compared to those not diagnosed with COVID-19, the post-COVID syndrome group more frequently experienced exercise intolerance (43% vs. 0%; P<.001), dyspnea (43% vs. 0%; P<.001), chest pain (31% vs 7%; P=.002), olfactory impairment (19% vs 0%; P=.004), lymphadenopathy (19% vs 0%; P=.004), gustatory impairment (14% vs 0%; P=.02), and appetite loss (36% vs 14%; P=.02). Interpretation/UNASSIGNED:Our results contradict the perception that this "yet to be defined" post-COVID syndrome predominantly affects middle-aged adults and suggest that exercise intolerance, dyspnea, chest pain, chemosensory impairment, lymphadenopathy, rhinitis, and appetite loss may differentiate post-COVID syndrome from general symptoms of pandemic, age, and academic related stress. These findings are also consistent with previous reports that females are more vulnerable to this post viral syndrome. Large-scale population-based studies are essential to discerning the magnitude and characterization of post-COVID syndrome in young adults as well as more diverse populations.
