RESUMO

This randomized controlled trial tested the Family Assessment and Feedback Intervention (FAFI), a new intervention to enhance family engagement with emotional and behavioral health services. The FAFI is a guided conversation with families about results of their multidimensional assessment that is set in the context of motivational enhancement. It differs from other assessment-with-feedback interventions by extending the focus of assessment beyond the target child to parents and the family environment, addressing parental emotional and behavioral problems and competencies, spanning a broad range of children's and parents' strengths and difficulties, and being generalizable to many settings and practitioners. Participants were 81 families in primary care pediatrics. The FAFI was associated with a significant increase in parental mental health literacy and with an increase in parental attitudinal engagement with health supports and services that closely approached statistical significance (p = .052), while controlling for children's age and gender and family socioeconomic status.

RESUMO

PROBLEM: Medical students experience psychological distress more frequently than age-matched peers. Tracking medical student well-being has typically been limited to once- or twice-per-year questionnaires. Ongoing, real-time assessment of student behavior and well-being could facilitate individualized, timely interventions. APPROACH: Faculty at the University of Vermont, in conjunction with the Larner College of Medicine Office of Medical Education, developed a novel smartphone app in 2021 called WE MD to track and support medical student wellness. The app included the following features: (1) nightly surveys assessing wellness-related behaviors (e.g., social interaction, sleep, exercise) and outcomes (i.e., mood, focus, stress, overall well-being); (2) health reports that enabled users to graph various combinations of their own behaviors and outcomes, allowing them to visualize trends and understand possible correlations between behaviors and outcomes; (3) a resource library with articles and educational videos related to specific wellness behaviors or outcomes; and (4) research-based "insights" or brief tips intended to promote healthy habits. Participants also received virtual "coins" for interacting with the app that could be exchanged for various items in an online store. OUTCOMES: The WE MD program enrolled a substantial portion of the medical school population (43%); most of the students used the app on a regular basis. Students found the app to be acceptable and appreciated many features and also provided feedback on how to improve the app. Information from the nightly survey data converged with established measures but also identified variability over time in wellness behaviors and outcomes. NEXT STEPS: Data from the WE MD program suggest that app-based daily tracking of wellness behaviors and outcomes is a feasible, promising approach to promote student wellness and identify real-time patterns and risk periods for medical students. The app will be revised based on student feedback and adapted for use by students, residents, and faculty.

RESUMO

Few studies have examined the association between conduct problems and cerebral cortical development. Herein, we characterize the association between age-related brain change and conduct problems in a large longitudinal, community-based sample of adolescents. 1,039 participants from the IMAGEN study possessed psychopathology and surface-based morphometric data at study baseline (M = 14.42 years, SD = 0.40; 559 females) and 5-year follow-up. Self-reports of conduct problems were obtained using the Strengths and Difficulties Questionnaire (SDQ). Vertex-level linear mixed effects models were implemented using the Matlab toolbox, SurfStat. To investigate the extent to which cortical thickness maturation was qualified by dimensional measures of conduct problems, we tested for an interaction between age and SDQ Conduct Problems (CP) score. There was no main effect of CP score on cortical thickness; however, a significant "Age by CP" interaction was revealed in bilateral insulae, left inferior frontal gyrus, left rostral anterior cingulate, left posterior cingulate, and bilateral inferior parietal cortices. Across regions, follow-up analysis revealed higher levels of CP were associated with accelerated age-related thinning. Findings were not meaningfully altered when controlling for alcohol use, co-occurring psychopathology, and socioeconomic status. Results may help to further elucidate neurodevelopmental patterns linking adolescent conduct problems with adverse adult outcomes.

RESUMO

This randomized controlled trial tested the Vermont Family Based Approach (VFBA) in primary care pediatrics. The VFBA is a model of healthcare delivery that shifts the focus from the individual to the family, emphasizes emotional and behavioral health, and uses evidence-based health promotion/prevention along with the treatment of emotional and behavioral problems. Participants were 81 families of 3-15-year-olds. For children, the VFBA was associated with greater reductions than the Control condition on the Child Behavior Checklist Emotionally Reactive, Withdrawn, Sleep Problems, Aggressive Behavior and Total Problems scales. For parents, the VFBA was associated with greater reductions than the Control condition on the Adult Self-Report Anxious/Depressed, Rule-Breaking Behavior, Internalizing Problems and Total Problems scales. The VFBA was also associated with greater improvement than the Control condition in the parents' health-related quality of life, as indicated by all scales of the Medical Outcomes Study Health Survey.

RESUMO

BACKGROUND: Personality traits are important factors with regard to the tendency to experience and response to stress. This study introduces and tests a new stress-related personality scale called the Virtual Inventory of Behavior and Emotions (VIBE). METHODS: Two samples totaling 5512 individuals (with 66% between the ages of 18 and 34) completed the VIBE along with other measures of personality, stress, mood, and well-being. RESULTS: Exploratory factor analyses revealed a four-factor structure for the instrument with dimensions labeled: 1) stressed; 2) energetic; 3) social; and 4) disciplined. Confirmatory factor analytic procedures on the final 23-item version showed good psychometric properties and data fit while machine learning analyses demonstrated the VIBE's ability to distinguish between groups with similar patterns of response. Strong convergent validity was suggested through robust correlations between the dimensions of the VIBE and other established rating scales. CONCLUSION: Overall, the data suggest that the VIBE is a promising tool to help advance understanding of the relations between stress, personality, and related constructs.

RESUMO

The Adolescent Brain Cognitive Development (ABCD) Study of 11,880 youth incorporates a comprehensive range of measures assessing predictors and outcomes related to mental health across childhood and adolescence in participating youth, as well as information about family mental health history. We have previously described the logic and content of the mental health assessment battery at Baseline and 1-year follow-up. Here, we describe changes to that battery and issues and clarifications that have emerged, as well as additions to the mental health battery at the 2-, 3-, 4-, and 5-year follow-ups. We capitalize on the recent release of longitudinal data for caregiver and youth report of mental health data to evaluate trajectories of dimensions of psychopathology as a function of demographic factors. For both caregiver and self-reported mental health symptoms, males showed age-related decreases in internalizing and externalizing symptoms, while females showed an increase in internalizing symptoms with age. Multiple indicators of socioeconomic status (caregiver education, family income, financial adversity, neighborhood poverty) accounted for unique variance in both caregiver and youth-reported externalizing and internalizing symptoms. These data highlight the importance of examining developmental trajectories of mental health as a function of key factors such as sex and socioeconomic environment.

RESUMO

Personality traits have been found to be related to a variety of health outcomes. The aim of this study was to examine how personality traits were associated with adjustment to the COVID pandemic in college students. The sample included 484 first-year university students (76% female) attending a northeastern university who completed the Big Five Inventory (BFI) personality assessment at the beginning of a semester that was disrupted by the COVID pandemic. Using a phone-based app, students completed daily ratings of mood, perceived stress levels, and engagement in a number of health promotion activities (exercise, mindfulness, adequate sleep, etc.) throughout the semester both before and after the onset of the pandemic (e.g., a within-person longitudinal design). Results, as expected, showed that mood and wellness indices generally declined during the COVID period, although stress levels actually decreased. Further, irrespective of COVID, improved mood, less perceived stress and greater participation in health promotion activities were significantly associated with a number of personality traits including neuroticism (lower), extraversion (higher), agreeableness (higher), and conscientiousness (higher). Of primary interest, mixed-effects models were used to test how major personality traits interacted with any changes in daily ratings from the pre-COVID to COVID period. Significant interactions terms were found suggesting differential impacts of the COVID epidemic for students with low versus high levels of particular traits. Higher levels of extraversion, for example, were found to be related to decreases in mood as the pandemic progressed in contrast to those with lower extraversion, for whom there was a slight increase in mood over time. These data support the conclusion that personality traits are related to mental health and can play a role in a person's ability to cope with major stressful events. Different traits may also be more adaptive to different types of stressors.

RESUMO

BACKGROUND: A high rate of bullying episodes has been reported in Italian schools, as well as its association with psychopathology in adolescents. However, information regarding moderators of this interaction are still lacking. This study explored whether gender, exercise frequency, and sport participation exerted a protective effect on the association between bullying and depressive symptoms in Italian students. METHODS: Researchers obtained data from 4,829 Italian youth ages 13 to 21 using the self-report Epidemiologia dell'Infortunistica Stradale survey (EDIT) developed by the Regional Health Agency of Tuscany, Italy. Three structural equation models were run to assess moderators of the association between bullying and depressive symptoms. Moderators examined in the models included gender, exercise frequency, and sport participation. RESULTS: The association between bullying and depressive symptoms was stronger for females (B=0.95, SE=0.04, p< .001) than for males (B=0.45, SE=0.00, p< .001) and for students who did not play sports (B=0.74, SE=0.09, p< .001) than for those who played sports (B=0.61, SE=0.06, p< .001). Females may be more affected by the depressive effects of bullying than males. CONCLUSIONS: Participation in sports buffers against the effects of bullying and may prove a helpful strategy for increasing exercise, positive peer interactions, and mood in adolescents. LIMITATIONS: The cross-sectional nature of the study, the possible role of BMI as a confounding factor and the use of a not widely used measure of depression.

RESUMO

BACKGROUND: Substantiated and unsubstantiated reports of maltreatment are associated with similar risk of emotional and behavioral problems. However, substantiation status often determines service provision. OBJECTIVE: We examined substantiated and unsubstantiated reports to identify patterns of recurrence over a five-year period and identified family risk factors that predicted recurrence patterns. PARTICIPANTS AND SETTING: We studied a subsample (N = 246,021) of the National Child Abuse and Neglect Data System from 2011-2015. METHODS: Measures included child, caregiver, and child protective services case characteristics obtained in 2011. We used latent class analysis to identify heterogeneous classes, then entered class membership as the outcome variable in a multinomial logistic regression to identify risk factors. RESULTS: Four latent classes emerged: (1) initial unsubstantiation and moderate recurrence, (2) initial unsubstantiation and low recurrence, (3) initial substantiation and moderate recurrence, and (4) initial substantiation and low recurrence. Domestic violence (relative risk ratio (RRR) = 2.56, ß = 0.94, SE = .02, p < .001), caregiver substance abuse (RRR=2.23, ß=0.80, SE=.02, p < .001), and Native Hawaiian/Pacific Islander race (RRR=1.67, ß=0.52, SE=.11, p < .001), predicted initial substantiation status but were not meaningful predictors of long-term recurrence. Prior substantiated report and poverty predicted initial substantiation status (report RRR=1.50, ß=0.41, SE=.02, p < .001; poverty RRR=1.50, ß=0.41, SE=.02, p < .001) and long-term recurrence (report RRR=2.60, ß=0.96, SE=.02, p < .001; poverty RRR = 1.35, ß=0.30, SE=.02, p < .001). Asian American race predicted low recurrence rates (RRR=2.09, ß=0.74, SE=.12, p < .001). CONCLUSIONS: Similar recurrence patterns between substantiated and unsubstantiated reports emphasize the importance of providing services regardless of substantiation status. Integrating administrative databases may reveal more variables that predict long-term recurrence.

RESUMO

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.

RESUMO

BACKGROUND: Exercise reduces the odds of sadness and suicidality in bullied students, but the role of the bullying environment on this relationship remains unknown. METHODS: Using combined data from the 2013 and 2015 Youth Risk Behavior Survey (N = 29,207), adjusted logistic regression models estimated odds ratios between exercise, sadness, and suicidal ideation and attempt, stratified by bullying exposure (electronically/at school). RESULTS: Overall, 40.2% of students bullied at school and 48.3% of students bullied electronically reported feeling sad, compared to 22.6% of those not bullied. Bullied students were 2-3 times more likely to report suicidal ideation, and 3-4 times more likely to report suicidal attempt, regardless of bullying context. Students who were bullied at school and exercised 4-7 days per week had lower odds of sadness (adjusted odds ratio [AOR]: 0.64; 95% confidence interval [CI]: 0.51-0.81), suicidal ideation (AOR: 0.66; 95% CI: 0.53-82), and suicidal attempt (AOR: 0.69; 95% CI: 0.48-0.98) compared to those who exercised 0-3 days. There were no protective effects of exercise for students bullied electronically. CONCLUSIONS: Exercise reduced sadness and suicidality in adolescents bullied at school but not for students who were cyberbullied. Bullying environment should be a primary consideration in school mental health treatment and maintenance paradigms.

RESUMO

In structural neuroimaging studies, reduced cerebral cortical thickness in orbital and ventromedial prefrontal regions is frequently interpreted as reflecting an impaired ability to downregulate neuronal activity in the amygdalae. Unfortunately, little research has been conducted in order to test this conjecture. We examine the extent to which amygdalar reactivity is associated with cortical thickness in a population-based sample of adolescents. Data were obtained from the IMAGEN study, which includes 2,223 adolescents. While undergoing functional neuroimaging, participants passively viewed video clips of a face that started from a neutral expression and progressively turned angry, or, instead, turned to a second neutral expression. Left and right amygdala ROIs were used to extract mean BOLD signal change for the angry minus neutral face contrast for all subjects. T1-weighted images were processed through the CIVET pipeline (version 2.1.0). In variable-centered analyses, local cortical thickness was regressed against amygdalar reactivity using first and second-order linear models. In a follow-up person-centered analysis, we defined a "high reactive" group of participants based on mean amygdalar BOLD signal change for the angry minus neutral face contrast. Between-group differences in cortical thickness were examined ("high reactive" versus all other participants). A significant association was revealed between the continuous measure of amygdalar reactivity and bilateral ventromedial prefrontal cortical thickness in a second-order linear model (p < 0.05, corrected). The "high reactive" group, in comparison to all other participants, possessed reduced cortical thickness in bilateral orbital and ventromedial prefrontal cortices, bilateral anterior temporal cortices, left caudal middle temporal gyrus, and the left inferior and middle frontal gyri (p < 0.05, corrected). Results are consistent with non-human primate studies, and provide empirical support for an association between reduced prefrontal cortical thickness and amygdalar reactivity. Future research will likely benefit from investigating the degree to which psychopathology qualifies relations between prefrontal cortical structure and amygdalar reactivity.

RESUMO

Few studies have investigated the link between putative biomarkers of attention-deficit/hyperactivity disorder (ADHD) symptomatology and genetic risk for ADHD. To address this, we investigate the degree to which ADHD symptomatology is associated with white matter microstructure and cerebral cortical thickness in a large population-based sample of adolescents. Critically, we then test the extent to which multimodal correlates of ADHD symptomatology are related to ADHD polygenic risk score (PRS). Neuroimaging, genetic, and behavioral data were obtained from the IMAGEN study. A dimensional ADHD composite score was derived from multi-informant ratings of ADHD symptomatology. Using tract-based spatial statistics, whole brain voxel-wise regressions between fractional anisotropy (FA) and ADHD composite score were calculated. Local cortical thickness was regressed on ADHD composite score. ADHD PRS was based on a very recent genome-wide association study, and calculated using PRSice. ADHD composite score was negatively associated with FA in several white matter pathways, including bilateral superior and inferior longitudinal fasciculi (p < 0.05, corrected). ADHD composite score was negatively associated with orbitofrontal cortical thickness (p < 0.05, corrected). The ADHD composite score was correlated with ADHD PRS (p < 0.001). FA correlates of ADHD symptomatology were significantly associated with ADHD PRS, whereas cortical thickness correlates of ADHD symptomatology were unrelated to ADHD PRS. Variation in hyperactive/inattentive symptomatology was associated with white matter microstructure, which, in turn, was related to ADHD PRS. Results suggest that genetic risk for ADHD symptomatology may be tied to biological processes affecting white matter microstructure.

RESUMO

INTRODUCTION: Family history of psychopathology is a risk factor for mood and anxiety disorders in children, but little is known about rates of parental psychopathology among treatment-seeking youth with affective disorders in the Asia Pacific region. This study examined patterns of emotional and behavioural problems in parents of clinically-referred youth in Singapore. We hypothesised that parents would have higher rates of affective disorders compared to the Singapore national prevalence rate of 12%. MATERIALS AND METHODS: In this cross-sectional study, 47 families were recruited from affective disorders and community-based psychiatry programmes run by a tertiary child psychiatry clinic. All children had a confirmed primary clinical diagnosis of depression or an anxiety disorder. Parents completed the Mini International Neuropsychiatric Interview (MINI) to assess for lifetime mood and anxiety disorders. They also completed the Adult Self Report (ASR) and Adult Behavior Checklist (ABCL) to assess current internalising and externalising symptoms. RESULTS: Consistent with our hypothesis, 38.5% of mothers and 10.5% of fathers reported a lifetime mood and anxiety disorder. Nearly 1/3 of mothers had clinical/subclinical scores on current internalising and externalising problems. A similar pattern was found for internalising problems among fathers, with a slightly lower rate of clinical/subclinical externalising problems. CONCLUSION: Our findings are consistent with previous overseas studies showing elevated rates of affective disorders among parents - particularly mothers - of children seeking outpatient psychiatric care. Routine screening in this population may help to close the current treatment gap for adults with mood and anxiety disorders.

RESUMO

Oestradiol is known to play an important role in the developing human brain, although little is known about the entire network of potential regions that might be affected and how these effects may vary from childhood to early adulthood, which in turn can explain sexually differentiated behaviours. In the present study, we examined the relationships between oestradiol, cortico-amygdalar structural covariance, and cognitive or behavioural measures typically showing sex differences (verbal/spatial skills, anxious-depressed symptomatology) in 152 children and adolescents (aged 6-22 years). Cortico-amygdalar structural covariance shifted from positive to negative across the age range. Oestradiol was found to diminish the impact of age on cortico-amygdalar covariance for the pre-supplementary motor area/frontal eye field and retrosplenial cortex (across the age range), as well as for the posterior cingulate cortex (in older children). Moreover, the influence of oestradiol on age-related cortico-amygdalar networks was associated with higher word identification and spatial working memory (across the age range), as well as higher reading comprehension (in older children), although it did not impact anxious-depressed symptoms. There were no significant sex effects on any of the above relationships. These findings confirm the importance of developmental timing on oestradiol-related effects and hint at the non-sexually dimorphic role of oestradiol-related cortico-amygdalar structural networks in aspects of cognition distinct from emotional processes.

RESUMO

BACKGROUND: Studies of white matter connectivity in children with disruptive behavior have yielded inconsistent results, possibly owing to the trait's heterogeneity, which comprises diverse symptoms like physical aggression, irritability, and delinquency. This study examined associations of global and specific white matter connectivity with childhood disruptive behavior problems, while accounting for their complex multidimensionality. METHODS: In a large cross-sectional population-based study of 10-year-old preadolescents (n = 2567), we assessed four previously described empirically derived dimensions of disruptive behavior problems using the Child Behavior Checklist: physical aggression, irritability, disobedient behavior, and delinquent behavior. Global and specific white matter microstructure was assessed by diffusion tensor imaging. RESULTS: Global fractional anisotropy and mean diffusivity were not associated with broad measures of disruptive behavior, e.g., Child Behavior Checklist externalizing problems scale. Global fractional anisotropy was negatively associated with delinquent behavior (ß = -.123, pfalse discovery rate adjusted = .028) and global mean diffusivity was positively associated with delinquent behavior (ß = .205, pfalse discovery rate adjusted < 0.001), suggesting reduced white matter microstructure in preadolescents with higher levels of delinquent behavior. Lower white matter microstructure in the inferior longitudinal fasciculus, superior longitudinal fasciculus, cingulum, and uncinate underlie these associations. Global white matter microstructure was not associated with physical aggression, irritability, or disobedient behavior. CONCLUSIONS: Delinquent behavior, a severe manifestation of childhood disruptive behavior, was associated with lower white matter microstructure in tracts connecting frontal and temporal lobes. These brain regions are involved in decision making, reward processing, and emotion regulation. This study demonstrated that incorporating the multidimensional nature of childhood disruptive behavior traits shows promise in advancing the search for elucidating neurobiological correlates of disruptive behavior.

RESUMO

BACKGROUND: Psychotic experiences comprise auditory and visual perceptive phenomena, such as hearing or seeing things that are not there, in the absence of a psychotic disorder. Psychotic experiences commonly occur in the general pediatric population. Although the majority of psychotic experiences are transient, they are predictive of future psychotic and non-psychotic disorders. They have been associated with sleep problems, but studies with objective sleep measures are lacking. This study assessed whether psychotic experiences were associated with actigraphic sleep measures, symptoms of dyssomnia, nightmares, or other parasomnias. METHODS: This cross-sectional population-based study comprises 4149 children from the Generation R Study. At age 10 years, psychotic experiences including hallucinatory phenomena were assessed by self-report; dyssomnia and parasomnia symptoms were assessed by mother- and child-report. Additionally, at age 11 years, objective sleep parameters were measured using a tri-axial wrist accelerometer in N = 814 children, who wore the accelerometer for five consecutive school days. RESULTS: Psychotic experiences were not associated with objective sleep duration, sleep efficiency, arousal, or social jetlag. However, psychotic experiences were associated with self-reported dyssomnia (B = 2.45, 95%CI: 2.13-2.77, p < 0.001) and mother-reported parasomnia, specifically nightmares (ORadjusted = 3.59, 95%CI 2.66-4.83, p < 0.001). Similar results were found when analyses were restricted to hallucinatory phenomena. CONCLUSIONS: Childhood psychotic experiences were not associated with objective sleep measures. In contrast, psychotic experiences were associated with nightmares, which are a known risk indicator of psychopathology in pre-adolescence. More research is needed to shed light on the potential etiologic or diagnostic role of nightmares in the development of psychotic phenomena.

RESUMO

The Adolescent Brain and Cognitive Development (ABCD) Study incorporates a comprehensive range of measures assessing predictors and outcomes related to both mental and physical health across childhood and adolescence. The workgroup developed a battery that would assess a comprehensive range of domains that address study aims while minimizing participant and family burden. We review the major considerations that went into deciding what constructs to cover in the demographics, physical health and mental health domains, as well as the process of selecting measures, piloting and refining the originally proposed battery. We present a description of the baseline battery, as well as the six-month interim assessments and the one-year follow-up assessments. This battery includes assessments from the perspectives of both the parent and the target youth, as well as teacher reports. This battery will provide a foundational baseline assessment of the youth's current function so as to permit characterization of stability and change in key domains over time. The findings from this battery will also be utilized to identify both resilience markers that predict healthy development and risk factors for later adverse outcomes in physical health, mental health, and substance use and abuse.
