ABSTRACT
Background: Because pediatric anxiety disorders precede the onset of many other problems, successful prediction of response to the first-line treatment, cognitive-behavioral therapy (CBT), could have major impact. However, existing clinical models are weakly predictive. The current study evaluates whether structural and resting-state functional magnetic resonance imaging can predict post-CBT anxiety symptoms. Methods: Two datasets were studied: (A) one consisted of n=54 subjects with an anxiety diagnosis, who received 12 weeks of CBT, and (B) one consisted of n=15 subjects treated for 8 weeks. Connectome Predictive Modeling (CPM) was used to predict treatment response, as assessed with the PARS; additionally we investigated models using anatomical features, instead of functional connectivity. The main analysis included network edges positively correlated with treatment outcome, and age, sex, and baseline anxiety severity as predictors. Results from alternative models and analyses also are presented. Model assessments utilized 1000 bootstraps, resulting in a 95% CI for R2, r and mean absolute error (MAE). Outcomes: The main model showed a mean absolute error of approximately 3.5 (95%CI: [3.1-3.8]) points a R2 of 0.08 [-0.14 - 0.26] and r of 0.38 [0.24 - 0.511]. When testing this model in the left-out sample (B) the results were similar, with a MAE of 3.4 [2.8 - 4.7], R2-0.65 [-2.29 - 0.16] and r of 0.4 [0.24 - 0.54]. The anatomical metrics showed a similar pattern, where models rendered overall low R2. Interpretation: The analysis showed that models based on earlier promising results failed to predict clinical outcomes. Despite the small sample size, the current study does not support extensive use of CPM to predict outcome in pediatric anxiety.
ABSTRACT
OBJECTIVE: Anxiety disorders are prevalent among youths and are often highly impairing. Cognitive-behavioral therapy (CBT) is an effective first-line treatment. The authors investigated the brain mechanisms associated with symptom change following CBT. METHODS: Unmedicated youths diagnosed with an anxiety disorder underwent 12 weeks of CBT as part of two randomized clinical trials testing the efficacy of adjunctive computerized cognitive training. Across both trials, participants completed a threat-processing task during functional MRI before and after treatment. Age-matched healthy comparison youths completed two scans over the same time span. The mean age of the samples was 13.20 years (SD=2.68); 41% were male (youths with anxiety disorders, N=69; healthy comparison youths, N=62). An additional sample including youths at temperamental risk for anxiety (N=87; mean age, 10.51 years [SD=0.43]; 41% male) was utilized to test the stability of anxiety-related neural differences in the absence of treatment. Whole-brain regional activation changes (thresholded at p<0.001) were examined using task-based blood-oxygen-level-dependent response. RESULTS: Before treatment, patients with an anxiety disorder exhibited altered activation in fronto-parietal attention networks and limbic regions relative to healthy comparison children across all task conditions. Fronto-parietal hyperactivation normalized over the course of treatment, whereas limbic responses remained elevated after treatment. In the at-risk sample, overlapping clusters emerged between regions showing stable associations with anxiety over time and regions showing treatment-related changes. CONCLUSIONS: Activation in fronto-parietal networks may normalize after CBT in unmedicated pediatric anxiety patients. Limbic regions may be less amenable to acute CBT effects. Findings from the at-risk sample suggest that treatment-related changes may not be attributed solely to the passage of time.

BACKGROUND: Anxiety disorders are among the most common psychiatric disorders in childhood and can develop as early as the preschool years. Therefore, providing young children who display early signs of anxiety with skills to prevent the development of later psychopathology is invaluable. The current study evaluates the effectiveness of Fun FRIENDS, an anxiety prevention and resilience program for young children. METHOD: Fifty-seven kindergartners across three classrooms participated in a 15-week anxiety prevention program and teachers completed a behavioral screening measure and anxiety questionnaire at pre, post, 3 month, and 10-month follow-up assessment points. RESULTS: Anxiety positively correlated with emotional symptoms, peer difficulties, and total difficulties at pre-intervention. Anxiety symptoms decreased from pre-intervention to follow-up. Additionally, prosocial behaviors improved and moderated the relationship between pre-and post-intervention anxiety symptoms. CONCLUSIONS: These findings yield promising implications regarding the effectiveness of prevention and intervention programs on increasing social emotional skills and reducing anxiety symptoms in young children.

Pediatric anxiety disorders are common, impairing, and chronic when not effectively treated. A growing body of research implicates family accommodation in the maintenance of pediatric anxiety. The present study aimed to quantify previously untested relations among family accommodation and two theoretically linked constructs: avoidance and self-efficacy. Eighty youths between ages 8 and 17 (53 with anxiety disorders, 27 non-anxious controls) completed measures of family accommodation and self-efficacy. In addition, avoidance was assessed using two distinct measures of avoidance: a clinician rating of real-world behaviors and a laboratory task-based index. As predicted, youths with anxiety disorders reported greater family accommodation than non-anxious controls. Across the sample, greater family accommodation was associated with greater avoidance, as measured using both clinician rating and the laboratory task, as well as with lower self-efficacy. In an exploratory mediation model, self-efficacy partially mediated the relation between family accommodation and clinician-rated avoidance; however, it did not mediate the relation between family accommodation and task-based avoidance. Considering the robust association between family accommodation and anxiety in youths, this addition to our understanding of related cognitive and behavioral factors provides important preliminary insight, which can guide future research on potential targets for early identification and intervention for pediatric anxiety.

Nighttime fears in children are common, interfere with daily functioning, and result in considerable disruption in the family. The aim of the present review was to examine empirical literature from the past 25 years that investigated the assessment of nighttime fears in young children and the efficacy and effectiveness of psychosocial treatments for children's nighttime fears. The last review of this literature was in 1997 and examined studies conducted in and prior to 1995 (King et al. in Clin Psychol Rev 17:431-443, 1997). Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a systematic review of the literature aimed at providing a synthesis of the Randomized Control Trials (RCTs) and controlled single-case multiple baseline design studies (MBLs) on the treatment of nighttime fears in children. A search of the literature identified 12 articles, with nine studies utilizing a between-group randomized controlled trial design and three studies utilizing a multiple baseline design. Results demonstrated significant improvements in children's nighttime fears and reductions in disruptive nighttime behaviors using behavioral interventions and cognitive-behavioral strategies. This review provides a commentary on the effectiveness and limitations of the assessment and treatment approaches for nighttime fears in children and suggests directions for future research.

Objective: Despite the advances in the field of neuroscience, many questions remain regarding the mechanisms of anxiety, as well as moderators of treatment outcome. Long-term adverse outcomes for anxious youth may relate to pathophysiologically based information processing patterns and self-referential beliefs, such as self-efficacy. In fact, there are no studies highlighting the relationship between self-efficacy and neurocircuitry in youth. The purpose of this study was to explore the relationships between self-efficacy, brain morphometry, and youth anxiety. Methods: Parent, child, and clinician ratings of anxiety symptoms and child-reported self-efficacy were analyzed in a sample of 8- to 17-year-old youth (n = 51). Measures were collected from all youth at baseline and during and after treatment for the patients. Anxious patients (n = 26) received 12 sessions of cognitive behavioral therapy (CBT). Moreover, imaging data obtained from all participants before treatment were utilized in analyses. Results: Patients reported lower self-efficacy than healthy volunteers. Across the entire sample, anxiety was negatively related to total, social, and emotional efficacy. Both social and emotional efficacy predicted anxiety posttreatment. In addition, social efficacy predicted social anxiety symptoms posttreatment and social efficacy increased across treatment. There were no significant relations between self-efficacy and neurocircuitry. Conclusions: Self-efficacy is an important treatment target for anxious youth. Although self-efficacy was not related to brain morphometry, self-efficacy beliefs may constitute an important mechanism through which CBT and psychopharmacological interventions decrease fear and anxiety symptoms in youth.

BACKGROUND: Attention bias modification training (ABMT) and cognitive behavioral therapy (CBT) likely target different aspects of aberrant threat responses in anxiety disorders and may be combined to maximize therapeutic benefit. However, studies investigating the effect of ABMT in the context of CBT have yielded mixed results. Here, we propose an enhanced ABMT to target the attentional bias towards threat, in addition to classic CBT for anxiety disorders in youth. This enhanced ABMT integrates the modified dot-probe task used in previous studies, where a target is always presented at the previous location of the neutral and not the simultaneously presented threatening stimulus, with a visual search, where the targets are always presented distally of threatening distractors. These two training elements (modified dot-probe and visual search) are embedded in an engaging game to foster motivation and adherence. Our goal is to determine the efficacy of the enhanced ABMT in the context of CBT. Further, we aim to replicate two previous findings: (a) aberrant amygdala connectivity being the neurobiological correlate of the attentional bias towards threat at baseline; and (b) amygdala connectivity being a mediator of the ABMT effect. We will also explore moderators of treatment response (age, sex, depressive symptoms and irritability) on a behavioral and neuronal level. METHODS: One hundred and twenty youth (8-17 years old) with a primary anxiety disorder diagnosis all receive CBT and are randomized to nine weeks of either active or control ABMT and symptom improvement will be compared between the two study arms. We will also recruit 60 healthy comparison youth, who along with eligible anxious youth, will be assessed with the dot-probe task during fMRI (anxious youth: before and after training; healthy volunteers: second measurement twelve weeks after initial assessment). DISCUSSION: The present study will contribute to the literature by (1) potentially replicating that aberrant amygdala connectivity mediates the attentional bias towards threat in anxious youth; (2) determining the efficacy of enhanced ABMT; and (3) advancing our understanding of the mechanisms underlying ABMT. TRIAL REGISTRATION: Clinicaltrials.gov: NCT03283930 Trial registration date: September 14th 2017. The trial registration took place retrospectively. Data acquisition started February 1st 2017.

The current study provides the first replication trial of Bounce Back, a school-based intervention for elementary students exposed to trauma, in a different school district and geographical area. Participants in this study were 52 1st through 4th graders (Mage = 7.76 years; 65% male) who were predominately Latino (82%). Schools were randomly assigned to immediate treatment or waitlist control. Differential treatment effects (Time × Group Interaction) were found for child-reported posttraumatic stress disorder (PTSD) and parent-reported child coping, indicating that the immediate treatment group showed greater reductions in PTSD and improvements in coping compared with the delayed group. Differential treatment effects were not significant for depression or anxiety. Significant maintenance effects were found for both child-reported PTSD and depression as well as parent-reported PTSD and coping for the immediate treatment group at follow-up. Significant treatment effects were also found in the delayed treatment group, showing reductions in child-reported PTSD, depression, and anxiety as well as parent-reported depression and coping upon receiving treatment. In conclusion, the current study suggests that Bounce Back is an effective intervention for reducing PTSD symptoms and improving coping skills, even among a sample experiencing high levels of trauma and other ongoing stressors.

This study examined the efficacy of Collaborative & Proactive Solutions (CPS) in treating oppositional defiant disorder (ODD) in youth by comparing this novel treatment to Parent Management Training (PMT), a well-established treatment, and a waitlist control (WLC) group. One hundred thirty-four youth (ages 7-14, 61.9% male, 83.6% White) who fulfilled Diagnostic and Statistical Manual of Mental Disorders (4th ed.) criteria for ODD were randomized to CPS, PMT, or WLC groups. ODD was assessed with semistructured diagnostic interviews, clinical global severity and improvement ratings, and parent report measures. Assessments were completed pretreatment, posttreatment, and at 6 months following treatment. Responder and remitter analyses were undertaken using intent-to-treat mixed-models analyses. Chronological age, gender, and socioeconomic status as well as the presence of comorbid attention deficit/hyperactivity and anxiety disorders were examined as predictors of treatment outcome. Both treatment conditions were superior to the WLC condition but did not differ from one another in either our responder or remitter analyses. Approximately 50% of youth in both active treatments were diagnosis free and were judged to be much or very much improved at posttreatment, compared to 0% in the waitlist condition. Younger age and presence of an anxiety disorder predicted better treatment outcomes for both PMT and CPS. Treatment gains were maintained at 6-month follow-up. CPS proved to be equivalent to PMT and can be considered an evidence-based, alternative treatment for youth with ODD and their families.

OBJECTIVE: Children's nighttime fears are a normal part of child development and are transient for most children, but result in considerable distress for others. The present study evaluated a 4-week bibliotherapy intervention designed to treat young children with persistent and interfering nighttime fears utilizing a multiple baseline design. METHOD: Nine children between 5 and 7 years of age with specific phobia diagnoses were randomized into one of three baseline control conditions (1, 2, or 3 weeks). The treatment protocol involved parents reading Uncle Lightfoot, Flip that Switch: Overcoming Fear of the Dark, Academic Version (Coffman, 2012) with their children over 4 weeks while engaging in activities prescribed in the book. Assessments took place at baseline, post treatment, and 1 month following treatment. Daily and weekly tracking of nighttime behaviors was also obtained. RESULTS: Pre-post group analyses revealed that eight of the nine children demonstrated clinically significant change in anxiety severity. In addition, decreases in child-reported nighttime fears were observed, as were parent-reported decreases in separation anxiety and increases in the number of nights children slept in their own bed. CONCLUSIONS: The present study provides initial support for the use of bibliotherapy in the treatment of nighttime fears. Further replication and evaluation are needed to determine appropriate length of treatment and long-term effects. Implications of the findings are discussed.

OBJECTIVE: Examine the efficacy of a parent-augmented One-Session Treatment (A-OST) in treating specific phobias (SP) in youth by comparing this novel treatment to child-focused OST, a well-established treatment. METHOD: A total of 97 youth (ages 6-15, 51.5% female, 84.5% White) who fulfilled diagnostic criteria for SP were randomized to either A-OST or OST. SPs were assessed with semistructured diagnostic interviews, clinician improvement ratings, and parent and child improvement ratings. In addition, measures of treatment satisfaction and parental self-efficacy were obtained. Blind assessments were completed pretreatment, posttreatment, and 1month and 6months following treatment. Analyses were undertaken using mixed models. In addition, gender, age, internalizing/externalizing problems, parent overprotection, and parent anxiety were examined as potential predictors and moderators of treatment outcome. RESULTS: Both treatment conditions produced similar outcomes with approximately 50% of youth in both treatments diagnosis free and judged to be much or very much improved at posttreatment and 1-month follow-up. At 6-month follow-up, however, the treatments diverged with OST resulting in marginally superior outcomes to A-OST, contrary to predictions. Only age of child predicted treatment outcome across the two treatments (older children did better); unexpectedly, none of the variables moderated treatment outcomes. CONCLUSIONS: Parent augmentation of OST produced no appreciable gains in treatment outcomes. Directions for future research are highlighted.

A host of factors including genetic influences, temperament characteristics, learning experiences, information processing biases, parental psychopathology, and specific parenting practices have been hypothesized to contribute to the development and expression of children's phobias. In the present study, the authors focused on parental psychopathology (phobic anxiety) and parenting behaviors (warmth, involvement) in the prediction of child performance on a behavioral approach test (BAT). All children (n = 44) experienced a phobia of animals and were clinic referred. The youth completed two BATs: the first alone and the second one with a parent present. Overall, performance was greater on the parent-present BAT (58% of steps completed) than on the child-alone BAT (38% of steps completed), although considerable variability was present. Performance on the parent-present BAT was associated with parental warmth and involvement but not parental phobic anxiety. Implications of these findings were discussed, and their implications for the use of behavioral analogues tests were explored.

The purpose of the present study was to determine the relations among negative life events, social support, coping and anxiety symptoms in 709 Caucasian and African-American youth between 11 and 14 years of age. Results indicated that more negative life events, less social support, more coping efforts, and African-American status were related to more anxiety symptoms. Additionally, although active coping moderated the relationship between negative life events and anxiety, these relations were qualified in separate analyses for the African-American and Caucasian youth. Negative life events were related to anxiety symptoms only for the African-American participants. When these findings were explored further for males and females of each racial group, negative life events remained significant for African-American males but not African-American females. Implications of these findings are examined and future directions for research to understand the processes underlying these relations with both Caucasian and African-American youth are addressed.
