Test-retest reliability of the Multidimensional Anxiety Scale for Children

Personality traits as predictors of depression across the lifespan

BACKGROUND

Depression is a major public health concern. A barrier for research has been the heterogeneous nature of depression, complicated by the categorical diagnosis of depression which is based on a cluster of symptoms, each with its own etiology. To address the multifactorial etiology of depression and its high comorbidity with anxiety, we aimed to examine the relations between personality traits, diverse behavioral, cognitive and physical measures, and depression and anxiety over the lifespan.

METHOD

Our sample was drawn from the NKI-RS, a community-based lifespan sample (N = 1494 participants aged 6 to 85). Analyses included multivariate approach and general linear models for group comparisons and dimensional analyses, respectively. A machine learning model was trained to predict depression using many factors including personality traits.

RESULTS

Depression and anxiety were both characterized by increased neuroticism and introversion, but did not differ between themselves. Comorbidity had an additive effect on personality vulnerability. Dimensionally, depression was only associated with personality in adolescence, where it was positively correlated with neuroticism, and negatively correlated with extraversion, agreeableness, and conscientiousness. The relationship between anxiety and personality changed over time, with neuroticism and conscientiousness being the most salient traits. Our machine learning model predicted depression with 70 % accuracy with neuroticism and extraversion contributing most.

LIMITATIONS

Due to the cross-sectional design, conclusions cannot be drawn about causal relationships between personality and depression.

CONCLUSION

These results underscore the impact of personality on depressive disorders and provide novel insights on how personality contributes to depression across the lifespan.

The long-term impact of cerebellar tumor resection on executive functioning, anxiety, and fear of pain: A mixed methodology pilot study

This pilot study investigated the long-term impact of a surgery-only treatment (no exposure to other treatments, such as chemotherapy and radiation) for pediatric cerebellar low-grade gliomas on executive function, anxiety, and fear of pain (FOP) beliefs. Twelve patients who underwent surgical glioma resection during childhood (surgery age was 4-16 years, study visit age was 10-28 years), and 12 pain-free controls matched for age, sex, race, and handedness were tested. The spatial extent of resection was precisely mapped using magnetic resonance imaging (MRI). Executive function, anxiety, and FOP were assessed using validated self-report age-appropriate questionnaires for children and adults. Structured clinical interviews at a post-surgery follow-up visit were completed (average: 89 months, range: 20-99). No significant differences in FOP (FOPQ-C t[14 = 1.81, p = 0.09; FOPQ-III t[4] = 0.29, p = 0.79), executive function scores (BRIEF t[20] = 0.30, p = 0.28), or anxiety scores (MASC t[16] = 0.19, p = 0.85; MAQ t[4] = 1.80, p = 0.15) were found in pediatric or adult patients compared to pain-free controls. Clinical interviews mainly categorized pediatric patients as not anxious. One participant reported mild/subclinical anxiety, and one had moderate clinical anxiety. Neither psychologists nor patients endorsed impairments to executive functioning, anxiety, or FOP. Our pilot results suggest that pediatric cerebellar tumor survivors treated with surgery-only have favorable long-term functioning related to these themes. While these results are promising, they will need to be replicated in a larger patient sample.

Emotional self-knowledge profiles and relationships with mental health indicators support value in 'knowing thyself'

"Know thyself" may be indicated by a balanced high pairing of two emotional self-knowledge indicators: attention to emotions and emotional clarity. Closely associated but often evaluated separately, emotional clarity is consistently, inversely associated with psychopathology, while evidence regarding attention to emotions is less consistent. Variables of high/low emotional clarity and attention to emotions yielded four emotional self-knowledge profiles which were analyzed for associations with mental health indicators (depression and anxiety symptoms, self-esteem, self-schema, resiliency, transcendence) in n = 264 adolescents. Here we report regression models which show that compared with neither, both high (attention + clarity) show higher positive self-schema (B = 2.83, p = 0.004), more resiliency (B = 2.76, p = 0.015) and higher transcendence (B = 82.4, p < 0.001), while high attention only is associated with lower self-esteem (B = - 3.38, p < 0.001) and more symptoms (B = 5.82, p < 0.001 for depression; B = 9.37, p < 0.001 for anxiety). High attention only is associated with most severe impairment all indicators excepting transcendence. Profiles including high clarity suggest protective effects, and 'implicit' versus 'explicit' emotional awareness are discussed. Balanced vs. imbalanced emotional self-awareness profiles dissimilarly affect mental health, which have implications for treatment and policy.

A transactional mediation model of risk for the intergenerational transmission of depression: The role of maternal criticism

In this study, we sought to combine two lines of research to better understand risk for the intergenerational transmission of depression. The first focuses on the role of maternal criticism as a potential mechanism of risk for depression in youth while the second builds from interpersonal and stress generation models regarding the potential impact of youth depression on future escalations in maternal criticism. Specifically, we examined the role of maternal criticism within a transactional mediation model using data from a multi-wave study. Participants were 251 mother-offspring pairs consisting of mothers with (n = 129) and without (n = 122) a history of major depressive disorder (MDD) during their child's lifetime who completed assessments every 6 months for 2 years. We found support for the hypothesized transactional mediational model in which maternal expressed emotion-criticism (EE-Crit) mediated the link between maternal history of MDD and residual change in youth's depressive symptoms over the previous 6 months and, reciprocally, youth depressive symptoms mediated the relation between maternal MDD history and residual change in EE-Crit 6 months later. These results indicate that maternal criticism and offspring depressive symptoms may contribute to a vicious cycle of depression risk, which should be considered for interventions targeted toward youth at risk of developing MDD.

Patterns of respiratory sinus arrhythmia and trajectories of anxiety and depressive symptoms in early adolescence

In children and adults, individual differences in patterns of respiratory sinus arrhythmia (RSA; i.e., interactions between resting RSA and RSA reactivity to stress) have emerged as a central predictor of internalizing symptoms. However, it is unclear whether individual differences in patterns of RSA also contribute to internalizing symptoms during the key developmental period of early adolescence, when rates of internalizing symptoms sharply increase. In the present multi-wave longitudinal study, we assessed whether patterns of RSA predicted trajectories of the two most common types of internalizing symptoms among adolescents: anxiety and depression. In the baseline session, we assessed RSA at rest and in response to a psychosocial stressor (Trier Social Stress Test [TSST]) in a sample of 75 early adolescents (Mage = 12.85). Youth then completed measures of anxiety and depressive symptoms at baseline and four times over approximately two years. Findings indicate that RSA patterns predicted trajectories of anxiety, but not depression. Specifically, region of significance analyses indicated that individuals with high resting RSA who demonstrated RSA augmentation to the lab stressor evinced decreasing anxiety over the follow-up period. In direct contrast, adolescents with high resting RSA in combination with RSA withdrawal to the stressor exhibited a trajectory of increasing anxiety. Findings provide preliminary evidence for understanding RSA as a developmentally salient risk or protective factor.

Relationships between Anxiety, Attention, and Reading Comprehension in Children

Many studies link anxiety in children with reading difficulties, but some facets of anxiety have been found to be positively associated with reading achievement. Attentional Control Theory offers a potential explanation for these seemingly contradictory findings, positing that anxiety can both interfere in attentional processes and enhance effort and use of compensatory processing strategies. The current study examines the relationships between anxiety, attentional control, and reading comprehension in a racially-diverse sample of 251 second-grade students, most of whom were struggling readers. Results showed that harm avoidance was positively associated with reading comprehension and physical symptoms of anxiety were negatively associated with reading comprehension. These links were attenuated when including attentional control in the model, suggesting mediation and lending support to Attentional Control Theory. Further research is needed to confirm causal mediation effects between anxiety, attentional control, and reading performance.

Relational victimization prospectively predicts increases in error-related brain activity and social anxiety in children and adolescents across two years

Recent research has focused on identifying neural markers associated with risk for anxiety, including the error-related negativity (ERN). An elevated ERN amplitude has been observed in anxious individuals from middle childhood onward and has been shown to predict risk for future increases in anxiety development. The ERN is sensitive to environmental influences during development, including interpersonal stressors. Of note, one particular type of interpersonal stressor, relational victimization, has been related to increases in anxiety in adolescents. We tested whether relational victimization predicts increases in the ERN and social anxiety symptoms across two years in a sample of 152 child and adolescent females (ages 8 - 15). Results indicated that children and adolescents' baseline ERN was positively related to the ERN two years later. Furthermore, greater relational victimization at baseline predicted greater increases in the ERN two years later, controlling for baseline ERN. Moreover, relational victimization at baseline predicted increases in social anxiety, and this relationship was mediated by increases in the ERN. These results suggest that relational victimization impacts the developmental trajectory of the neural response to errors and thereby impacts increases in social anxiety among children and adolescents.

Randomized Controlled Trial of a Mindfulness Mobile Application for Ruminative Adolescents

OBJECTIVE

Rumination is a risk factor for the development of internalizing psychopathology that often emerges during adolescence. The goal of the present study was to test a mindfulness mobile app intervention designed to reduce rumination.

METHOD

Ruminative adolescents (N = 152; 59% girls, 18% racial/ethnic minority, Mage = 13.72, SD = .89) were randomly assigned to use a mobile app 3 times per day for 3 weeks that delivered brief mindfulness exercises or a mood monitoring-only control. Participants reported on rumination, depressive symptoms and anxiety symptoms at baseline, post-intervention and at 3 follow-up timepoints: 6 weeks, 12 weeks, and 6 months post-intervention. Parents reported on internalizing symptoms.

RESULTS

There was a significant Time X Condition effect at post-intervention for rumination, depressive symptoms, and anxiety symptoms, such that participants in the mindfulness intervention showed improvements relative to those in the control condition. The effect for rumination lasted through the 6-week follow-up period; however, group differences were generally not observed throughout the follow-up period, which may indicate that continued practice is needed for gains to be maintained.

CONCLUSIONS

This intervention may have the potential to prevent the development of psychopathology and should be tested in a longitudinal study assessing affective disorder onset, especially in populations with limited access to conventional, in person mental health care.This study was registered with Clinicaltrials.gov (Identifier NCT03900416).

Sooner is Better: Longitudinal Relations Between Delay Discounting, and Depression and Anxiety Symptoms among Vietnamese Adolescents

Delay discounting refers to the decline in the present value of an outcome as a function of the delay to its receipt. Research on delay discounting initially focused on substance abuse, generally finding that greater delay discounting is associated with increased risk for and severity of substance abuse. More recently, delay discounting has been linked theoretically and empirically to affective psychopathology, potentially suggesting novel intervention targets for mental health problems such as depression and anxiety. Longitudinal research consequently is critical to determine direction of causality and rule out possible third variable explanations. Only a small number of longitudinal studies have been conducted in this area, however. Furthermore, socio-economic and socio-cultural factors may influence delay discounting and its effects, but thus far the literature is relatively limited in this regard. The present study focused on adolescence, a key time-period for development of delay discounting and emotional problems. Longitudinal relations between delay discounting, and depression and anxiety symptoms were assessed among 414 adolescents in Vietnam, a lower-middle-income Southeast Asian nation with significant cultural divergence from Western countries. In contrast to most cross-sectional studies that have found positive or non-significant correlations, in the present study delay discounting at Time 1 had a negative beta with anxiety and depression symptoms at Time 1, with preference for immediate but smaller rewards (higher discounting) at Time 1 associated with lower anxiety and depression symptoms at Time 2. These results suggest that under certain circumstances, steeper delay discounting may be adaptive and supportive of emotional mental health.

Breathing out dental fear: A feasibility crossover study on the effectiveness of diaphragmatic breathing in children sitting on the dentist's chair

BACKGROUND

Anxiety related to the dental context is a clinically significant challenge. In children, dental fear is often accompanied by disruptive and uncooperative behaviours that can render treatment difficult. Although techniques to reduce children's anxiety exist, many have not been formally evaluated.

DESIGN

Diaphragmatic breathing has been shown to reduce fear and anxiety, but few investigations have evaluated whether it can reduce dental anxiety in children. This crossover study tested the effectiveness and feasibility of diaphragmatic breathing in twenty children undergoing dental care.

RESULTS

Compared with the treatment as usual, such a simple technique had significant benefits on mood, self-reported pain and autonomic balance, thus reducing sympathetic activation.

CONCLUSION

Diaphragmatic breathing is a low-cost, easy-to-implement technique suitable for daily dental practice, and is a promising tool for reducing negative effect and physiological distress in children with dental anxiety that results in more cooperative behaviours and reduced visit time.

A Content Analysis of Self-report Child Anxiety Measures

A clear understanding of the item content of psychological assessments is critical but often overlooked. This study describes the content overlap of seven commonly used and psychometrically validated measures of anxiety among children and adolescents. Symptom codes were created for all items across measures and items were sorted by these codes, which all fell into specific symptom categories. We conducted two analyses of all items: a "bottom-up" content categorization approach, which used symptom categories that were developed during this study, and a "top-down" DSM-5 categorization which mapped items onto symptoms of anxiety disorders in the DSM-5. Findings reveal a weak mean overlap across the included measures of youth anxiety. This suggests that the scope of anxiety measures should be carefully considered when designing studies, interpreting research, or assessing youth in clinical practice. Further research is needed to develop and establish a coding scheme for a more objective, comprehensive content analysis.

Long-term safety and maintenance of efficacy of sodium oxybate in the treatment of narcolepsy with cataplexy in pediatric patients

STUDY OBJECTIVES

Evaluate long-term efficacy and safety of sodium oxybate (SXB) in children and adolescents (aged 7-16 years) with narcolepsy with cataplexy.

METHODS

A double-blind randomized withdrawal study was conducted. Prior to randomization, SXB-naive participants were titrated to an efficacious and tolerable dose of SXB; participants taking SXB entered on their established dose. Following a 2-week stable-dose period and 2-week, double-blind, randomized withdrawal period, participants entered an open-label period (OLP; ≤ 47 weeks). Efficacy measures during the OLP included number of weekly cataplexy attacks, cataplexy-free days, and Epworth Sleepiness Scale for Children and Adolescents (ESS-CHAD). Safety outcomes included treatment-emergent adverse events; assessments of depression, anxiety, and suicidality; and polysomnography.

RESULTS

Of 106 enrolled participants, 95 entered and 85 completed the OLP. In SXB-naive participants and participants previously taking SXB, efficacy of SXB established prior to the double-blind, randomized withdrawal period was maintained throughout the OLP for number of weekly cataplexy attacks (median [quartile 1, quartile 3] change from the stable-dose period to end of the OLP: 0.0 [-2.5, 4.9] and 0.0 [-3.4, 2.6], respectively) and ESS-CHAD scores (0.0 [-3.0, 2.5] and 1.0 [-3.0, 3.0], respectively). The median (quartile 1, quartile 3) number of cataplexy-free days per week was 2.3 (0.0, 6.0) in OLP week 1 and 3.8 (0.5, 5.5) in week 48. Treatment-emergent adverse events (≥ 5%) were enuresis, nausea, vomiting, headache, decreased weight, decreased appetite, nasopharyngitis, upper respiratory tract infection, and dizziness.

CONCLUSIONS

SXB demonstrated long-term maintenance of efficacy in pediatric narcolepsy with cataplexy, with a safety profile consistent with that observed in adults.

Review: Meta-analysis on mindfulness-based interventions for adolescents' stress, depression, and anxiety in school settings: a cautionary tale

BACKGROUND

Mindfulness-based interventions (MBIs) have been applied in school settings for adolescents with symptoms of stress, depression, and anxiety; however, general conclusions of the efficacy of such interventions remain unclear. This meta-analysis reviewed randomized-controlled MBI trials for stress, depression, and anxiety in school settings.

METHODS

One hundred one records were included after removing duplicates. Nine studies met inclusion criteria, totalling 5046 adolescents aged 12-18. Eighteen comparisons between an MBI and a control group were analyzed.

RESULTS

The overall effect for symptoms of the 17 observations including stress, depression, and anxiety resulted in a significant improvement with a small effect size (k = 17, n = 3721, Hedge's g = .33, CI 95% .17-.49 p < .01). Subgroup analysis revealed that when MBIs were compared to an active control group effects were not significant (k = 5, n = 2753, Hedge's g = .27, CI 95% -.03-.57 p = .08), and when compared to an inactive control group the effect was significant with a small effect size (k = 5, n = 1065, Hedge's g = .38, CI 95% .02-.75 p < .05). Analysis of the interventions on a per symptom basis yielded a significant and moderate effect size for perceived stress (k = 7, n = 1116, Hedge's g = .55, CI 95% .31-.79 p < .01); however, there were no significant effects for depression (k = 6, n = 3172, Hedge's g = .20, CI 95% -.05-.44 p < .01) and anxiety (k = 4, n = 837, Hedge's g = .19, CI 95% -.14-.53 p = .25).

CONCLUSIONS

The impact of MBIs in school settings for adolescents yielded a significant improvement for stress, but did not for depression and anxiety. The effects were significant when compared to inactive controls, but not when compared to active controls. Implications of these findings are discussed.

Development and initial validation of the Visual Social Anxiety Scale (VSAS): Could a picture be worth a thousand words?

Accurate assessment is crucial for determining appropriate therapeutic interventions for social anxiety and conducting sound clinical research. While self-report measures of social anxiety are widely used in both research and clinical settings, they have several drawbacks inherent to their textual nature. Here, we describe the development and initial validation of the Visual Social Anxiety Scale (VSAS), a novel picture-based self-report measure of social anxiety, based on the well-established widely-used Liebowitz Social Anxiety Scale (LSAS). Specifically, the 24 items of the LSAS were used as the basis for social situations to be included in the VSAS. First, pictures to serve as VSAS items were selected using a rigorous two-phase process (four pilot studies; n = 225). Next, reliability (internal consistency, test-retest) and validity (convergent, discriminant) were explored with new participants (n = 304) who completed the VSAS and a battery of additional self-report questionnaires, delivered in a random order. The VSAS was completed again a month later (n = 260/304). The VSAS showed high internal consistency and test-retest reliability, and good convergent and discriminant validities. VSAS correlations with convergent measures were significantly greater than its correlations with discriminant measures. Thus, the VSAS shows initial promise as a novel picture-based self-report measure of social anxiety.

School-aged children with higher anxiety symptoms show greater correspondence between subjective negative emotions and autonomic arousal

Individuals exhibit variability in the degree of correspondence between autonomic and subjective indicators of emotional experience. The current study examined whether convergence between autonomic arousal and negative emotions during emotion-inducing story vignettes is associated with internalizing symptoms in school-aged children. A diverse sample of 97 children aged 8 to 12 years participated in this study in which they reported on their anxiety and depression. Children's electrodermal activity was assessed while they read vignettes depicting children experiencing sadness and fear. Participants also reported on their emotional reaction to the vignettes. Children's anxiety and electrodermal activity to fear vignettes were associated only at high levels, but not mean or low levels, of self-reported negative emotions to fear vignettes. These findings suggest that hyperawareness, in which self-reported negative emotionality is high when physiological reactivity is also high, is associated with greater risk for anxiety, but not depression, during middle childhood.

Meta-mood knowledge moderates the relationship between neuroticism and depression but not between neuroticism and anxiety in a sample of nonclinical adolescents

Research shows a strong link between neuroticism and internalizing psychopathology, such as depression and anxiety. However, it is unclear to what extent meta-mood knowledge (i.e., attention to emotion and emotional clarity) plays a role as a moderator in this relationship. To investigate this, we collected data on meta-mood knowledge, personality traits, depression, and anxiety in a sample of adolescents (N = 244; 53.7% girls) aged 12 to 18 years (M = 14.6, SD = 1.7) from Catalonia, Spain. Regarding the relationship between neuroticism and depression, results showed that emotional clarity buffered this relationship. Although attention to emotion did not, the joint moderating effect of attention to emotion and emotional clarity was significant. The results on the four different combinations of attention to emotion and emotional clarity showed that the relationship between neuroticism and depression was strongest for high attention and low clarity, less strong for low attention and low clarity, and even lower for high attention and high clarity. And importantly, these similar patterns of association disappeared at low attention and high clarity. In contrast to the relationship between neuroticism and depression, we found no statistically significant moderating effects for the relationship between neuroticism and anxiety. Based on these results, we argue the importance of examining individual differences in emotion-based cognition and understanding when the benefits of emotional clarity are associated with fewer disadvantages of excessive attention. These results provide preliminary evidence that the combination of low attention and high clarity may be an adaptive version of emotional self-awareness in relation to neuroticism and depression.

Cognitive Beliefs Across the Symptom Dimensions of Pediatric Obsessive-Compulsive Disorder: Type of Symptom Matters

The cognitive model of obsessive-compulsive disorder (OCD) posits that dysfunctional cognitive beliefs are crucial to the onset and maintenance of OCD; however, the relationship between these cognitive beliefs and the heterogeneity of OCD symptoms in children and adolescents remains unknown. We examined how the major belief domains of the cognitive model (inflated responsibility/threat estimation, perfectionism/intolerance of uncertainty, importance/control of thoughts) and dysfunctional metacognitions were related to OCD symptoms across the following dimensions: doubting/checking, obsessing, hoarding, washing, ordering, and neutralization. Self-report ratings from 137 treatment-seeking youth with OCD were analyzed. When cognitive beliefs and symptom dimensions were analyzed in tandem, inflated responsibility/threat estimation and dysfunctional metacognitions were uniquely related to doubting/checking, obsessing, and hoarding and perfectionism/intolerance of uncertainty to ordering. Cognitive beliefs explained a large proportion of variation in doubting/checking (61%) and obsessing (46%), but much less so in ordering (15%), hoarding (14%), neutralization (8%), and washing (3%). Similar relations between cognitive beliefs and symptom dimensions were present in children and adolescents. Cognitive beliefs appear to be relevant for pediatric OCD related to harm, responsibility, and checking, but they do not map clearly onto contamination and symmetry-related symptoms. Implications for OCD etiology and treatment are discussed.

Psychometric Properties of the Obsessive Compulsive Inventory-Child Version in Iranian Clinical and Community Samples

This study evaluated the psychometric properties of the Persian version of the Obsessive-Compulsive Inventory-Child Version (OCI-CV) in clinical and community samples. Factor structure (confirmatory factor analysis), validity (convergent/discriminant, and predictive), and reliability (internal consistency, and 4-week retest) of the Persian version of the OCI-CV were investigated in a sample of 391 children and adolescents 7-17 years comprised of two groups: a clinical sample of youth with OCD (n = 62), and a community sample (n = 329). Participants completed the OCI-CV, Multidimensional Anxiety Scale for Children (MASC), Children's Depression Inventory (CDI), and Child Behavior Checklist (CBCL). Similar to the English version of the OCI-CV, the Persian version of the scale demonstrated a stable six-factor structure, good convergent and discriminant validity through its correlations with other specific measures of pediatric psychopathology, acceptable sensitivity and specificity for the detection of OCD, and good reliability in terms of internal consistency and temporal stability. These findings suggest that the OCI-CV is a valid and reliable measure to assess obsessive-compulsive symptom dimensions in Iranian youth. Findings provide cross cultural support on the utility of OCI-CV as a self-report measure of obsessive-compulsive symptomology.

Characterizing Neurocognitive Impairment in Juvenile Fibromyalgia Syndrome: Subjective and Objective Measures of Dyscognition

OBJECTIVES

Our understanding of brain fog, or dyscognition, among youth with juvenile fibromyalgia syndrome is limited. We aimed to determine the prevalence of subjective (self-reported) and objective dyscognition, as well as factors associated with subjective dyscognition in juvenile fibromyalgia syndrome.

METHODS

A cross-sectional cohort study of patients (n = 31) 12-17 years old diagnosed with primary juvenile fibromyalgia syndrome and one of their parents from 2017 to 2019. Subjects completed a series of survey measures and patients completed a brief neurocognitive battery. Subjective dyscognition was determined based on scores on the Pediatric Quality of Life Inventory (PedsQL) Cognitive Functioning Scale and Behavior Rating Inventory of Executive Function (BRIEF-2) global executive composite (GEC). Objective dyscognition was defined as impairment of more than two standard deviations in any of the neurocognitive domains. We used Fisher's exact test or Wilcoxon rank-sum test, as appropriate, to compare clinical patients based on the presence of dyscognition. Multivariable logistic regression modeling was performed to determine factors associated with subjective dyscognition.

RESULTS

Of the 31 subjects, 65% reported subjective dyscognition and 39% had objective dyscognition, primarily in the domains of psychomotor speed (23%), executive function (23%), and attention (3%). Subjective dyscognition was not indicative of objective dyscognition. Subjective dyscognition was independently associated with functional disability (OR: 1.19 [95% CI: 1.02-1.40]) and anxiety (OR: 1.12 [95% CI: 1.02-1.24]).

DISCUSSION

Adolescents with fibromyalgia predominantly experience subjective dyscognition but more than 1/3 also experience objective dyscognition. Future research should explore the impact of interdisciplinary rehabilitation programs on the treatment of dyscognition in youth with JFMS.

Anxiety-related shifts in smell function in children and adolescents

Anxious adults show changes in smell function that are consistent with a durable shift in sensitivity toward particular odorants and away from others. Little is known regarding the development of these changes, including whether they exist in youth, are stable during the transition from childhood to adolescence, and whether odorant properties (e.g. trigeminal features, hedonic valence) affect anxiety-related differences in detection. To address this, we measured smell detection thresholds to phenyl ethyl alanine (PEA), a rose-like odorant with little trigeminal properties, and guaiacol (GUA), a smoke-like odorant with high trigeminal properties. These thresholds were measured at baseline and after an acute stress challenge, the Trier Social Stress Tests, in 131 healthy youth (in 4th, 7th, and 10th grades, age 9-16 years) that reported normal to elevated levels of anxiety. At baseline, high anxious youth exhibited heightened sensitivity to GUA coupled with reduced sensitivity to PEA, as well as a further exaggeration of this bias with acute stress. Importantly, sex, age, and hedonic valence moderated the relationship between trait anxiety and sensitivity to both odorants. Smell function and its aberrations are often overlooked in the literature on biomarkers of stress and anxiety. Taken together with the extant literature, these findings suggest that greater attention is warranted to characterize potential novel olfactory therapeutic targets-across the lifespan.

The Impact of Television, Electronic Games, and Social Technology Use on Sleep and Health in Adolescents with an Evening Circadian Preference

There are mixed findings when examining if technology use is harmful for adolescent sleep and health. This study builds on these mixed findings by examining the association between technology use with sleep and health in a high-risk group of adolescents. Adolescents with an evening circadian preference (N = 176; 58% female, mean age = 14.77, age range = 10-18) completed measures over one week. Sleep was measured via actigraphy. Technology use and health were measured using ecological momentary assessment. Technology use was associated with an increase in sleep onset latency; with better emotional, social, cognitive, and physical health; and with worse behavioral health. This study offers support for technology use having some benefits and expands research on technology use to adolescents with an evening circadian preference.

Psychometric properties of the Brief Problem Monitor (BPM) in children with internalizing symptoms: examining baseline data from a national randomized controlled intervention study

BACKGROUND

Prevention is essential to reduce the development of symptomology among children and adolescents into disorders, thereby improving public health and reducing costs. Therefore, easily administered screening and early assessment methods with good reliability and validity are necessary to effectively identify children's functioning and how these develop. The Brief Problem Monitor (BPM) is an instrument designed for this purpose. This study examined the psychometric properties of the Norwegian version of the BPM parent (BPM-P) and teacher (BPM-T) versions, including internal reliability and construct validity at assessing children with internalizing problems.

METHODS

Baseline data were collected from a national randomized controlled intervention study. Children aged 8-12 years with self-reported symptoms of anxiety and/or depression with one standard deviation above a chosen population's mean were included in this study. Teachers (n = 750) and parents (n = 596) rated children using the BPM-T and BPM-P, respectively. Internal consistency was measured using Cronbach's alpha, and multi-informant agreement between the BPM-P and BPM-T was measured using Spearman's correlations. Construct validity was assessed via confirmatory factor analysis.

RESULTS

Internal consistency was good throughout all domains for both the BPM-P and BPM-T, with a Cronbach's alpha ranging from .763 to .878. Multi-informant agreement between the parents and the teacher was moderate on the externalizing, attention, and total scales and low on the internalizing scale. The model fit for the three-factor structure of the BPM was excellent for the BPM-P and good for the BPM-T.

CONCLUSIONS

Internal consistency was good, and the original three-factor solution of the BPM-P and BPM-T was confirmed based on our sample of school children at-risk for emotional problems. These promising results indicate that the BPM may be a valid short assessment tool for measuring attentional, behavioral, and internalizing problems in children. Trial registration in Clinical Trials: NCT02340637; June 12, 2014.

Acceptability and Preliminary Effects of a Mindfulness Mobile Application for Ruminative Adolescents

Rumination is a transdiagnostic risk factor that appears to be reduced through mindfulness interventions. However, mindfulness mobile apps have not been tested for their effects on rumination, especially among adolescents. Thus, we aimed to test the acceptability and effects of a mindfulness mobile intervention among ruminative adolescents using a within-subjects pretest/posttest design. Participants were 80 adolescents ages 12-15, selected for moderate-to-high rumination (M age = 14.01, SD = .99; 46.2% girls; 86.25% White; 3.75% Hispanic). We asked adolescents to use our mindfulness app 3 times per day for 3 weeks. Participants and parents completed questionnaires at baseline, post-intervention, and 6 and 12 weeks later. Acceptability was assessed by tracking app use and asking adolescents and parents to report on their experiences post-intervention. We assessed repetitive negative thinking (i.e., rumination and worry) and internalizing symptoms via self- and parent-report. The intervention demonstrated acceptability, and there were significant reductions in rumination, worry, anxiety and parent-reported internalizing symptoms post-intervention. Effects on rumination, anxiety and internalizing symptoms persisted throughout the 12-week follow-up with large effect sizes using an intention-to-treat approach. Thus, a brief mindfulness mobile app intervention appeared to be both engaging and helpful in reducing negative repetitive thinking and internalizing symptoms among ruminative adolescents. It will be important to test this intervention in a randomized controlled trial to control for effects of time and attention.

Internet use and its impact on internalizing disorder symptoms and sleep in adolescents with an evening circadian preference

STUDY OBJECTIVES

This study sought to examine the relationship between internet use, sleep, and internalizing disorder symptoms in adolescents with an evening circadian preference.

METHODS

One hundred seventy-two adolescents aged 10-18 years with an evening circadian preference completed a week of sleep diaries and questionnaires about internet use and internalizing disorder symptoms.

RESULTS

Adolescents reported internet use for 3.81 hours on weekdays and 5.44 hours on weekends, with > 90% having access to both a computer with internet and a personal cell phone. A majority of adolescents used the internet from 4-8 pm (71%) and from 9-11 pm (62%). Common online activities included listening to music (77%), watching videos (64%), communicating with others (64%), and doing homework (58%). Late-night internet use (9-11 pm) was associated with more internalizing disorder symptoms. Middle-of-the-night internet use (midnight-5 am) was associated with a later bedtime, shorter total sleep time, and more internalizing disorder symptoms. Adolescents used the internet to fulfill social needs, to avoid or combat boredom, or for maladaptive activities. Using the internet for social interaction or avoidance/boredom was associated with higher internalizing disorder symptoms. Using the internet for maladaptive reasons was associated with more late-night and middle-of-the-night use.

CONCLUSIONS

Adolescent internet use late at night and in the middle of the night is common. Internet use may be motivated by desires for social connection, by boredom/avoidance, or for maladaptive behaviors. Because middle-of-the-night internet use was associated with higher internalizing disorder symptoms and worse sleep, it presents as a potential target for intervention.

Meditation Effects on Anxiety and Resilience of Preadolescents and Adolescents: A Randomized Controlled Study

Meditation has been described as having a positive impact on well-being while reducing anxiety and stress among those who practice, mainly working as a resource to cope with everyday difficulties. As a simple and easy to apply meditation technique, transcendental meditation (TM) has shown promising results in adults and in children, although more studies are needed to show the impact on psychological and behavioral dimensions in children and adolescents. This quasi-experimental, pre-test–post-test study, with a control group, aimed to evaluate the impact of TM on the stress and resilience of children and adolescents, with ages between 9 and 16 years old. Participants were selected within schools which implemented the Quiet Time Program (QT), from those who volunteered to participate. They were randomly assigned to an experimental group (immediate TM learning) and to a control group (delayed TM learning). A repeated measures ANOVA showed an interaction of time and group on externalizing behavior, from the strengths and difficulties measure. The experimental group decreased on externalizing less adjusted behaviors, while the control group increased in this aspect, after a twelve-week period. TM failed to reduce anxiety and to contribute to resilience in the TM experimental group. Both groups improved anxiety indicators. The results might suggest students were acting upon their expectation of improvement on practicing TM or solely modifying their behavior along the contextual factors, which affected both groups equally.

The Role of Social Skills in Predicting Treatment-Recovery in Children with a Social Anxiety Disorder

The current study investigated the role of social skills and its interaction with social anxiety as predictors of treatment outcome in children with an anxiety disorder either with or without a social anxiety disorder (SoAD). In total, 133 children (aged 8 to 13) with an anxiety disorder received a 10-session cognitive behavioral treatment (FRIENDS program). Pre- to post treatment Reliable Change (RC) and Treatment-Recovery (TR) were assessed from a multi-informant perspective, by including diagnostic information (ADIS C/P), child-reported anxiety symptoms (MASC) and parent-reported internalizing symptoms (CBCL-Int). Social skills were assessed with the parent-rated Social Skills Rating System (assertion, self-control, responsibility). Results showed that 1) parents of children with a SoAD reported significantly less favorable use of assertive and responsible social behavior in their children pre-treatment than parents of children without SoAD, 2) children with higher social skills had a better treatment recovery, and 3) children with anxiety and higher responsible behavior pre-treatment and without a SoAD had a better treatment recovery, but this effect did not show for children with SoAD. In conclusion, better use of social behavior increased the likelihood of treatment recovery but not of reliable change. Further studies on the role of social skills in the treatment of childhood (social) anxiety are needed to investigate the mechanisms by which social skills impact treatment outcome.

Assessment and Treatment of Anxiety in Children with Autism Spectrum Disorder in School Settings: A Systematic Review and Meta-Analysis

Anxiety is the most common mental health problem that occurs with Autism Spectrum Disorder (ASD), and due to creating a more inclusive learning environment, children with ASD are placed in general education classrooms. Thus, addressing anxiety problems for children with ASD in school settings become critically important. This systematic review and meta-analysis investigated the current qualities of studies and the effects of school-based interventions for reducing anxiety in children with ASD. The study included six studies with a total of 165 participants. A random-effect meta-analysis yielded a moderate overall effect (g =  − 0.58, 95% CI [− 0.96, − 0.20], z =  − 3.01, p < .05) with no significant heterogeneity, Q (5) = 7.31, p = 0.20. Findings of the systematic review indicated that school-based interventions for anxiety problems are still in the early stages, and studies showed significant issues with adaptations of current clinical-based interventions and anxiety measurements to use in school settings for children with ASD. Interpretation of these findings and implications are discussed.

A Comparison between Severe Suicidality and Nonsuicidal Self-Injury Behaviors in Bipolar Adolescents Referred to a Psychiatric Emergency Unit

Background: Severe suicide ideation or attempts and non-suicidal self-injury (NSSI) present both differences and relevant overlaps, including frequent co-occurrence and shared risk factors. Specific categorical diagnoses, namely bipolar disorder (BD), may affect clinical features and natural histories of suicidal or not suicidal self-harm behaviour. Our study aimed to compare suicidality (severe suicidal ideation or suicidal attempts) and NSSI in referred bipolar adolescents. Methods: The sample included 95 bipolar adolescents (32 males, 63 females) aged 11 to 18 years. Thirty adolescents with suicide attempts/suicidal ideation and BD (SASIB) were compared with structured measures to 35 adolescents with NSSI and BD, without suicidal ideation or attempts (NSSIB), and to 30 adolescents with BD, without suicidal ideation or attempts or NSSI (CB). Results: Compared to CB, suicidality and NSSI were both associated with female sex, borderline personality disorder and self-reported internalizing disorders, anxiety/depression and thought disorders. The NSSI were specifically associated with somatic problems. Severe suicidal ideation and suicide attempts were associated with adverse life events, immigration, bullying, eating disorders, social problems, depressive feelings, performance and social anxiety, and feelings of rejection. Conclusions: Both shared and differential features between suicidal and not suicidal adolescents may represent possible targets for diagnostic and preventative interventions.

Differential Risk Factor Profiles in the Prediction of General and Pain-Specific Functional Limitations 12 Months after Major Pediatric Surgery

Pediatric chronic post-surgical pain is a surgical complication associated with various levels of functional limitation. Two commonly used measures of functional limitations in youth are the Functional Disability Inventory (FDI) and the PROMIS Pediatric Pain Interference Scale (PPIS), where the former is general, and the latter, pain specific. The aim of the present study was to prospectively compare pre-surgical youth and parent risk factors for youth functional limitations, assessed by the FDI and PPIS, 12 months after major pediatric surgery. Risk factors for the FDI and PPIS were compared in 79 dyads consisting of youth (58% female, M = 14.56 years; SD = 2.31) undergoing major surgery and one of their parents. The FDI and PPIS were highly correlated prior to surgery (r = 0.698, p < 0.001) and even more so 12 months after surgery (r = 0.807, p < 0.001). Parent pre-surgical anxiety sensitivity and youth pre-surgical functional disability significantly predicted 12-month FDI (F(6,56) = 4.443, p = 0.001, Adjusted R² = 0.25), whereas parent pre-surgical anxiety sensitivity, trait anxiety, pain anxiety, as well as youth pain-related anxiety and worry significantly predicted 12-month PPIS (F(6,45) = 4.104, p = 0.002, Adjusted R² = 0.27). Risk factors for 12-month general and pain-specific functional limitations differ by dyad member and type. Functional limitations in youth after surgery are predicted by youth and parent factors, however the risk factors differ between the FDI and the PPIS.

A brief session-by-session measure of eating disorder psychopathology for children and adolescents: Development and psychometric properties of the Eating Disorder-15 for Youth (ED-15-Y)

OBJECTIVE

Despite evidence supporting the use of measures to track ongoing progress and outcome in treatment, there is a relative absence of measures that are appropriate for this purpose in youth with eating disorders. This study examined the psychometric properties of the Eating Disorder-15 for Youth (ED-15-Y) scale, including its ability to detect short-term change in symptomatology.

METHOD

Youth (N = 203) ages 8-18 years completed self-report questionnaires and semi-structured diagnostic interviews upon initial presentation for an outpatient eating disorders assessment at an academic medical center.

RESULTS

The ED-15-Y demonstrated excellent reliability (internal consistency, split-half reliability) and high sensitivity to change early in treatment (change from sessions 1 to 8, adjusting for baseline score). Further, these data demonstrate that the ED-15-Y has excellent convergent validity, being highly correlated with a well-tested, longer measure of eating disorders psychopathology-the Eating Disorders Examination-Questionnaire (EDE-Q). These data also support good discriminant and concurrent validity, differentiating between youth without an eating disorder or with ARFID and youth with eating disorders involving weight and shape concerns (e.g., anorexia nervosa, bulimia nervosa).

DISCUSSION

The ED-15-Y may be a useful tool to briefly assess eating disorder psychopathology in youth as young as 8 years old. Its sensitivity to change very early in treatment suggests that it has the potential to be used as a routine outcome measure in the context of treatment.

Psychometric Evaluation of the Intolerance of Uncertainty Scale for Children (IUSC): Findings From Clinical and Community Samples in Iran

OBJECTIVE

The present study examined the psychometric properties of a Persian version of the Intolerance of Uncertainty Scale for Children (IUSC; Comer et al, 2009).

METHOD

Participating youth (n = 346) 8 to 18 years of age were nonreferred community youth (n = 279) or youth who met diagnostic criteria for an anxiety disorder (n = 67) and their parents.

RESULTS

Across child- and parent-report data, confirmatory factor analysis supported a shortened 12-item version of the IUSC, and the confirmatory factor analysis also confirmed a theory-driven correlated two-factor structure of the IUSC-12. (i.e., prospective/inhibitory IU). Results further supported reliability and validity of parent- and child-reports of the Persian IUSC-12 via evidence of internal consistency, 4-week retest, significant associations with established measures of internalizing problems, and the ability of the measure to reliably distinguish the clinical sample from the community sample.

CONCLUSION

Findings demonstrate sound psychometric properties of the Persian version of the IUSC-12 and provide additional support for the reliability and validity of the measure and its use in non-Western cultures. Findings are discussed in terms of implications for assessment, treatment, and study of anxiety and related internalizing problems in Iranian youth.

Beyond 16 Sessions: Extending Manualized Treatment of Anxious Youth

Cognitive behavioral therapy (CBT) is well established as an efficacious treatment for anxious youth, yet a number of youth remain symptomatic after the 10-16 sessions of treatment stipulated by most CBT treatment manuals. While a significant minority do not respond, no study has examined the frequency and impact of additional therapy sessions. This study examined youth receiving outpatient therapy at an anxiety clinic who were offered the option to continue treatment after completing 16 sessions of manual-based CBT. Fifty-nine percent of participants chose to continue treatment, with an average of approximately 20 total sessions across participants. Therapist ratings demonstrated a significant overall improvement between session 16 and the final session. No pre-treatment measure of symptom severity differed between those who extended treatment and those who ended at session 16. Parent-rated anxiety differed between groups at session 16, as did the length of time between the pre-treatment assessment and week 16 assessments. Findings indicate that extending treatment is not uncommon, is typically limited to several additional sessions, and is associated with an increase in treatment gains. Current results suggest that two factors at session 16, parental perceptions of anxiety and time to complete 16 sessions, are influential and may be central to the decision to continue treatment past this point. Clinical implications and future directions are discussed.

Sympathetic nervous system dominance during stress recovery mediates associations between stress sensitivity and social anxiety symptoms in female adolescents

Social anxiety disorder (SAD) is commonly diagnosed during adolescence and is associated with psychological stress reactivity and heightened physiological arousal. No study, however, has systematically examined which aspects of autonomic nervous system function mediate likely links between stress sensitivity and social anxiety symptoms in adolescents. Here, we assessed 163 adolescents (90 females; 12.29 ± 1.39 years) with respect to life stress and social anxiety symptoms, and measured respiratory sinus arrhythmia (RSA) and skin conductance levels (SCL) during a psychosocial stress paradigm. We operationalized stress sensitivity as the residual variance in subjective stress severity after accounting for objective severity and changes in autonomic regulation using standardized change scores in RSA and SCL. In females only, stress sensitivity and social anxiety symptoms were significantly correlated with each other (p < .001) and with autonomic regulation during both reactivity and recovery (all ps < 0.04). Further, sympathetic nervous system dominance during recovery specifically mediated associations between stress sensitivity and social anxiety symptoms (B = 1.06, 95% CI: 0.02-2.64). In contrast, in males, stress sensitivity, autonomic regulation during reactivity or recovery, and social anxiety symptoms were not significantly associated (all ps > 0.1). We interpret these results in the context of psychobiological models of SAD and discuss implications for interventions targeting autonomic processes.

Suicidal risk and resilience in juvenile fibromyalgia syndrome: a cross-sectional cohort study

BACKGROUND

To characterize suicidality among youth with juvenile fibromyalgia syndrome (JFMS) receiving treatment from pediatric rheumatologists at a tertiary care center in order to determine the prevalence of suicidality in JFMS and to explore risk factors for persistent suicidal ideation.

METHODS

We performed a cross-sectional cohort study of children 12-17 years old with JFMS seen in a specialty pediatric rheumatology pain clinic from 7/2017-9/2019. All subjects completed patient-reported outcomes measures, complemented by retrospective chart review. Subjects who endorsed item 8 on the Children's Depression Inventory, 2nd Edition (CDI-2) were categorized as endorsing suicidal ideation. We assessed for differences between the suicidal and non-suicidal patients using Wilcoxon-rank sum test. Logistic regression modeling was performed to identify psychosocial factors associated with suicidality.

RESULTS

Of the 31 subjects, more than one-quarter endorsed suicidality. Nearly 90% of teens with suicidal ideation were established in outpatient counseling. In bivariate analyses, suicidality was associated with lower resilience and greater depression and anxiety (all p < 0.05). Pain intensity trended towards a statistically significant positive association (OR: 1.16 [0.99-1.37]; p = 0.06). Lower resilience was independently associated with suicidality (OR: 0.90 [95% CI: 0.82-0.98]; p < 0.02).

CONCLUSIONS

Suicidality was prevalent among youth with JFMS and persistent despite concurrent receipt of mental health services. Higher patient-level resilience was independently associated with a reduced odds of suicidality. Future work should examine the role of resilience training on reducing psychological distress and mitigating the risk of suicidality in JFMS.

Using Evaluative Criteria to Review Youth Anxiety Measures, Part I: Self-Report

Evidence-based assessment serves several critical functions in clinical child psychological science, including being a foundation for evidence-based treatment delivery. In this Evidence Base Update, we provide an evaluative review of the most widely used youth self-report measures assessing anxiety and its disorders. Guided by a set of evaluative criteria (De Los Reyes & Langer, 2018), we rate the measures as Excellent, Good, or Adequate across their psychometric properties (e.g., construct validity). For the eight measures evaluated, most ratings assigned were Good followed by Excellent, and the minority of ratings were Adequate. We view these results overall as positive and encouraging, as they show that these youth anxiety self-report measures can be used with relatively high confidence to accomplish key assessment functions. Recommendations and future directions for further advancements to the evidence base are discussed.

Fear of movement in children and adolescents undergoing major surgery: A psychometric evaluation of the Tampa Scale for Kinesiophobia

BACKGROUND

The objective of this study was to evaluate the psychometric properties of the 17-item Tampa Scale for Kinesiophobia (TSK) in youth.

METHODS

Participants were 264 children and adolescents (58.7% female, M_age  = 14.1 years, SD_age  = 2.51) scheduled for major surgery who were assessed before surgery, while in hospital postoperatively, and at 6 and 12 months after surgery. Exploratory factor analyses (EFA) were conducted to determine the factor structure of pre-operative TSK scores. Reliability, and convergent, discriminant, and predictive validity were examined.

RESULTS

EFA on the 17-item TSK revealed a two-factor model distinguishing the 13 positively scored items from the 4 reverse scored items, but the fit was poor. A second EFA was conducted on the 13 positively scored items (TSK-13) revealing a three-factor model: Fear of injury, bodily vulnerability, and activity avoidance. The TSK-13 showed adequate internal consistency (Ω = 0.82) and weak convergent validity. The TSK-13 was not correlated with postoperative, in-hospital physical activity (actigraphy; r (179) = -0.10, p = 0.18) and showed adequate discriminant validity, that is correlations less than 0.70, with measures of depression (r (225) = 0.41, p < 0.001) and general anxiety (r (224)=0.35, p < 0.001). Predictive validity for pain-related disability at 12 months (r (70) = 0.34, p < 0.001) was adequate.

CONCLUSIONS

The original TSK-17 does not appear to be a meaningful measure of kinesiophobia in youth after surgery possibly because of the syntactic structure of the reverse scored items. In contrast, a modified TSK-13, comprised of only the positively scored items, revealed a 3-factor structure that is reliable and demonstrates adequate convergent, discriminant, and predictive validity.

SIGNIFICANCE

Kinesiophobia is an important construct to evaluate in the transition from acute to chronic pain among children and adolescents. The 17 item Tampa Scale for Kinesiophobia (TSK) does not show adequate validity or reliability in youth undergoing major surgery, however, the psychometric properties of a 13-item modified scale (TSK-13) are promising.

Do changes in psychosocial factors, lifestyle factors and sitting posture influence the likelihood of musculoskeletal pain in high school computer users?

OBJECTIVES

Adolescents regularly engage in screen-based activities. Complex factors influence adolescents' growth, and habitual sitting posture. The association between over-time changes in their sitting posture, and upper quadrant musculoskeletal pain (UQMP) is poorly understood. This study tested the association between change over 12 months in seated posture angles (neck flexion [NF]; craniocervical angle [CCA] into flexion and extension; and thoracic flexion [TF]), UQMP, and predictor variables (anxiety and depression; sport activity, music participation; computer use).

METHODS

A one-year prospective longitudinal study enrolled 211 asymptomatic 15-18-year students. 3D motion analysis captured postural angles while students worked on desktop computers, at baseline and 12 months later. Height, weight, computing time, sport and music participation, and depression and anxiety were measured at both time periods. UQMP in the previous month was captured at 12 months. The association between over-time change in sitting posture angles and predictor variables was determined using linear regression analysis (r² ; p-values). The association between predictor variables with UQMP, and predictor variables on the association between postural angles and UQMP was assessed using logistic regression models (Odds Ratios [95%CI]). Significant confounding effects were determined when the addition of a predictor variable to the posture-UQMP model significantly changed the Likelihood Ratio chi square value.

RESULTS

N = 153 students (72%) completed the study (48 with UQMP). Significant associations occurred between head flexion (HF) and body mass index (BMI) (r²⁼ 4.20, p = .01); NF and computer use (r²⁼ 2.87, p = .036) and CCA and music participation (r²⁼ 9.99, p = .047). Music participants and non-participants in sport or music had increased risk of UQMP with CCA changes into flexion (OR 12.0) and TF changes into extension (OR 7.6) respectively.

CONCLUSION

The association between over-time-change in sitting posture angles and UQMP is not influenced by anthropometrics, psychosocial factors or time spent computing. Music students, and students not participating in sport, require further postural analysis.

Identifying Psychological Pathways to Polyvictimization: Evidence from a Longitudinal Cohort Study of Twins from the United Kingdom

OBJECTIVES

Examine the extent to which cognitive/psychological characteristics predict later polyvictimization. We employ a twin-based design that allows us to test the social neurocriminology hypothesis that environmental factors influence brain-based characteristics and influence behaviors like victimization.

METHODS

Using data from the Environmental Risk Longitudinal Twin Study (N = 1986), we capitalize on the natural experiment embedded in a discordant-twin design that allows for the adjustment of family environments and genetic factors.

RESULTS

The findings indicate that self-control, as well as symptoms of conduct disorder and anxiety, are related to polyvictimization even after adjusting for family environments and partially adjusting for genetic influences. After fully adjusting for genetic factors, only self-control was a statistically significant predictor of polyvictimization.

CONCLUSION

The findings suggest polyvictimization is influenced by cognitive/psychological characteristics that individuals carry with them across contexts. Policies aimed at reducing victimization risks should consider interventions that address cognitive functioning and mental health.

Intolerance of uncertainty in youth: Psychometrics of the Intolerance of Uncertainty Index-A for Children

Intolerance of uncertainty (IU) is a cognitive vulnerability for pathological anxiety. The current study adapted the Intolerance of Uncertainty Index-A for Children (IUI-A-C), and created a single-item Intolerance of Uncertainty Clinician-Rated Index (IUCR), both of which assess a youth's general inability to endure uncertainty. Psychometric properties of these two measures were evaluated. Participants were 146 youth aged 7-17 years seeking treatment for anxiety. The IUI-A-C evidenced individual item performance (i.e., correlations between each item and the total remainder score > .40, ps <.001), internal consistency, convergent validity with the IUCR and self-report measures of anxiety and functional impairment, divergent validity with ADHD severity, and retest reliability with a mean interval of over four weeks. The IUCR also evidenced convergent validity with the IUI-A-C and self-report measures of anxiety and functional impairment and divergent validity with ADHD severity. The IUI-A-C predicted composite principal diagnosis severity but did not predict composite GAD diagnosis severity. The IUI-A-C and IUCR have utility as measures of IU in youth. The role of IU in specific anxiety disorders and future research are discussed.

Translation and cross-cultural adaptation of the Brazilian version of the Reading Anxiety Scale: Short version

Abstract Reading anxiety refers to a negative emotional reaction to the reading process that causes the individual to avoid activities involving reading. To date, there are no instruments to evaluate this construct validated for Brazilian children. This study presents the cultural adaptation of the short version of the Reading Anxiety Scale and the study of its psychometric properties. The adaptation was conducted following standardized procedures: translation of the instrument into Brazilian Portuguese; synthesis of translated versions; evaluation by expert referees; evaluation of the instrument by the target audience; back-translation; pilot study with a clinical sample; preparation of the Reading Anxiety Scale short version; pilot study with typically developed children and the instrument psychometric properties. Factor analisys was used to reduce the number of items of the original scale. The studies of internal consistency and convergent validity suggest initial evidence of validity for the use of this instrument to investigate reading anxiety in Brazilian children.

School functioning and internalizing problems in young schoolchildren

Background

Symptoms of anxiety and depression are common mental health problems in children and are often referred to as internalizing symptoms. Youth with such symptoms are at greater risk for poor academic achievement, school non-completion, and future mental health problems, all of which, lead to public health consequences and costs to society. The aim of the current study was to investigate associations between young school children’s internalizing symptoms and school functioning, as assessed separately by the teachers and the children.

Methods

This study is a cross-sectional study including children (N = 750. 58% girls) from the ages of 8–12 years with elevated levels of self-reported symptoms of anxiety (MASC-C) and/or depression (SMFQ). Teachers reported the academic achievement, school adaptation (TRF) and internalizing symptoms (BPM-T) of the children. Associations were analyzed using linear regression analyses.

Results

Both teacher-reported internalizing symptoms and children’s self-reported depressive symptoms were associated with poor academic achievement and school adaptation, while self-reported symptoms of anxiety were not. Symptoms of depression as assessed by the children were associated with teacher-rated internalizing symptoms, while self-reported symptoms of anxiety were not.

Conclusion

We found negative associations between school functioning and internalizing symptoms, as assessed by both the teachers and the children. The dual findings strengthen the validity of these relationships. Thus, prevention of depressive and anxiety symptoms in children may lead to positive changes in school domains such as academic achievement and school adaptation. We also identified a negative association between teacher-rated internalizing symptoms and children’s self-report of depressive symptoms, indicating that teachers may have difficulties recognizing children with these symptoms.

Pediatric Chronic Postsurgical Pain And Functional Disability: A Prospective Study Of Risk Factors Up To One Year After Major Surgery

BACKGROUND

Chronic postsurgical pain (CPSP) is a surgical complication associated with increased functional disability, psychological distress, and economic costs. The aims of this paper were to prospectively: (1) examine the incidence of CPSP 6 and 12 months after pediatric major surgery; (2) identify pain intensity and pain unpleasantness trajectories before, and up to 12 months after, surgery; (3) identify pre-operative factors that predict pain trajectory group membership; and (4) identify predictors of 12-month functional disability.

METHODS

This study followed 265 children aged 8-17 years at four time points (pre-surgical [T0], in-hospital [T1], 6 [T2] and 12 [T3] months after surgery). Children and parents completed pain and psychological questionnaires. In-hospital physical activity was monitored using actigraphy.

RESULTS AND DISCUSSION

The incidence of moderate-to-severe CPSP at 6 and 12 months was 35% (95% CI 29.1% to 41.9%) and 38% (95% CI 32.4% to 45.1%), respectively. Three percent (95% CI 1.17% to 6.23%) and 4% (95% CI 1.45% to 6.55%) of children reported using opioids to manage pain at 6 and 12 months, respectively. Growth mixture modeling revealed a two-class trajectory model with a quadratic slope best fit the data for both pain intensity (Bayesian information criterion [BIC] = 3977.03) and pain unpleasantness (BIC = 3644.45) over the 12 months. Preoperative functional disability and cumulative in-hospital opioid consumption predicted pain intensity trajectories. Preoperative functional disability predicted pain unpleasantness trajectories. Preoperative functional disability (OR: 1.05, 95% CI: 1.01 to 1.09) and pain unpleasantness trajectories (OR: 2.59, 95% CI: 1.05 to 6.37) predicted 12-month moderate-to-severe functional disability.

CONCLUSION

Pre-surgical functional disability is the only factor that predicts both 12-month functional disability and the course of pain intensity and pain unpleasantness ratings over the 12-month period.

Parental Demandingness and Executive Functioning in Predicting Anxiety among Children in a Longitudinal Community Study

Theoretical models and empirical studies of anxiety have predominately focused on the main effects of various predictors such as executive functioning deficits on anxiety. This study examined the moderating role of parental demandingness in the relationship between executive functioning deficits and anxiety in children. Ninety children (46.67% female) aged from 9 to 14 years completed several executive functioning tasks and a measure of anxiety. Parental demandingness was rated based on an observation of parent-child interactions. The children completed the anxiety measure again at one-year follow-up. The results showed that parental demandingness significantly moderated the prospective relationship between executive functioning deficits and anxiety, such that the association between executive functioning deficits and anxiety in children was weaker when parental demandingness was lower. These findings suggest that low parental demandingness may serve as a protective factor that buffers the detrimental effects of executive functioning deficits on anxiety.

Emotional Awareness Predicts Specific Cognitive-Behavioral Therapy Outcomes for Anxious Youth

The current study examined emotional awareness as a predictor of differential outcomes for youth treated for an anxiety disorder. 37 youth ages 7-15 received either individual cognitive-behavioral therapy or family cognitive-behavioral therapy to treat generalized anxiety disorder, separation anxiety disorder, and/or social phobia. Diagnoses were determined by independent evaluators, following semi-structured interviews (ADIS-IV-C/P) with youth and their parents. Self-report questionnaires, including the multidimensional anxiety scale for children and the emotion expressivity scale for children, were completed at pre- and posttreatment. Youth with higher levels of pretreatment emotional awareness had better treatment outcomes than youth with lower levels of emotional awareness, with specific regard to improved ability to cope with worry. Findings suggest that higher levels of emotional awareness facilitate better specific outcomes for anxious youth. Findings highlight the importance of understanding the emotions associated with worry during the treatment process.
