ABSTRACT
BACKGROUND: Children and adolescents demonstrate diverse patterns of symptom change and disorder remission following cognitive behavioural therapy (CBT) for anxiety disorders. To better understand children who respond sub-optimally to CBT, this study investigated youths (N = 1,483) who continued to meet criteria for one or more clinical anxiety diagnosis immediately following treatment or at any point during the 12 months following treatment. METHODS: Data were collected from 10 clinical sites with assessments at pre-and post-treatment and at least once more at 3, 6 or 12-month follow-up. Participants were assigned to one of three groups based on diagnostic status for youths who: (a) retained an anxiety diagnosis from post to end point (minimal responders); (b) remitted anxiety diagnoses at post but relapsed by end point (relapsed responders); and (c) retained a diagnosis at post but remitted to be diagnosis free at end point (delayed responders). Growth curve models assessed patterns of change over time for the three groups and examined predictors associated with these patterns including demographic, clinical and parental factors, as well as treatment factors. RESULTS: Higher primary disorder severity, being older, having a greater number of anxiety disorders, having social anxiety disorder, as well as higher maternal psychopathology differentiated the minimal responders from the delayed and relapsed responders at the baseline. Results from the growth curve models showed that severity of the primary disorder and treatment modality differentiated patterns of linear change only. Higher severity was associated with significantly less improvement over time for the minimal and relapsed response groups, as was receiving group CBT, when compared to the delayed response group. CONCLUSIONS: Sub-optimal response patterns can be partially differentiated using variables assessed at pre-treatment. Increased understanding of different patterns of change following treatment may provide direction for clinical decision-making and for tailoring treatments to specific groups of clinically anxious youth. Future research may benefit from assessing progress during treatment to detect emerging response patterns earlier.
ABSTRACT
BACKGROUND: Despite broad recognition of the central role of avoidance in anxiety, a lack of specificity in its operationalization has hindered progress in understanding this clinically significant construct. The current study uses a multimodal approach to investigate how specific measures of avoidance relate to neural reactivity to threat in youth with anxiety disorders. METHODS: Children with anxiety disorders (ages 6-12 years; n = 65 for primary analyses) completed laboratory task- and clinician-based measures of avoidance, as well as a functional magnetic resonance imaging task probing neural reactivity to threat. Primary analyses examined the ventral anterior insula (vAI), amygdala, and ventromedial prefrontal cortex (vmPFC). RESULTS: Significant but distinct patterns of association with task- versus clinician-based measures of avoidance emerged. Clinician-rated avoidance was negatively associated with right and left vAI reactivity to threat, whereas laboratory-based avoidance was positively associated with right vAI reactivity to threat. Moreover, left vAI-right amygdala and bilateral vmPFC-right amygdala functional connectivity were negatively associated with clinician-rated avoidance but not laboratory-based avoidance. LIMITATIONS: These results should be considered in the context of the restricted range of our treatment-seeking sample, which limits the ability to draw conclusions about these associations across children with a broader range of symptomatology. In addition, the limited racial and ethnic diversity of our sample may limit the generalizability of findings. CONCLUSION: These findings mark an important step towards bridging neural findings and behavioral patterns using a multimodal approach. Advancing understanding of behavioral avoidance in pediatric anxiety may guide future treatment optimization by identifying individual-specific targets for treatment.

Psychological accommodation and control may help explain the finding that anxiety is more severe and common in Hispanic youth. Research with White samples conceptualizes psychological control as part of an authoritarian parenting style; however, research with Hispanic families suggests that psychological control is more likely to be indicative of a protective parenting style. Based on these findings, we hypothesized that in Hispanic families, psychological control would be related to protective parenting behaviors that ultimately maintain child anxiety. We tested a cross-sectional model hypothesizing that in Hispanic families the link between ethnicity and anxiety would be mediated through psychological control and parental accommodation of child anxiety, a parenting behavior which protects the child from the aversive experiences in the moment but ultimately serves to maintain child anxiety. A sample of mothers (n = 145; 48% Hispanic) and fathers (n = 59; 48% Hispanic) of youth from 8 to 18 years of age completed a survey assessing anxiety and parenting. With Hispanic mothers, the relation between ethnicity (Hispanic/non-Hispanic) and child anxiety was mediated through psychological control and accommodation. With fathers, although control was related to accommodation which, in turn, was related to child anxiety, ethnicity was not associated with control, accommodation, or child anxiety. Findings suggest that the context of parenting behavior should be considered in research, and adaptations of child anxiety treatments should consider ways to allow parents to express their desire to communicate warmth and protectiveness while avoiding negative reinforcement of child anxiety.
ABSTRACT
Although youth anxiety treatment research has focused largely on severe and impairing anxiety levels, even milder anxiety levels, including levels that do not meet full criteria for a diagnosis, can be impairing and cause for concern. There is a need to develop and test viable treatments for these concerning anxiety levels to improve functioning and reduce distress. We present findings from a randomized controlled efficacy trial of attention bias modification treatment (ABMT) and attention control training (ACT) for youths with concerning anxiety levels. Fifty-three clinic-referred youths (29 boys, M ageâ¯=â¯9.3 years, SD ageâ¯=â¯2.6) were randomized to either ABMT or ACT. ABMT and ACT consisted of attention-training trials in a dot-probe task presenting angry and neutral faces; probes appeared in the location of neutral faces in 100% of ABMT trials and 50% of ACT trials. Independent evaluators provided youth anxiety severity ratings; youths and parents provided youth anxiety severity and global impairment ratings; and youths completed measures of attention bias to threat and attention control at pretreatment, posttreatment, and 2-month follow-up. In both arms, anxiety severity and global impairment were significantly reduced at posttreatment and follow-up. At follow-up, anxiety severity and global impairment were significantly lower in ACT compared with ABMT. Attention control, but not attention bias to threat, was significantly improved at follow-up in both arms. Changes in attention control and attention focusing were significantly associated with changes in anxiety severity. Findings support the viability of attention training as a low-intensity treatment for youths with concerning anxiety levels, including levels that do not meet full criteria for a diagnosis. Superior anxiety reduction effects in ACT highlight the critical need for mechanistic research on attention training in this population.

Humans influence each other's emotions. The spread of emotion is well documented across behavioral, psychophysiological, and neuroscientific levels of analysis, but might this influence also be evident in language (e.g., are people more likely to use emotion words after hearing someone else use them)? The current study tests whether mothers and children influence each other's use of affective language. From 2018 to 2020, children aged 6-12 who met diagnostic criteria for anxiety disorders and their mothers (N = 93 dyads) completed a challenging puzzle task while being video recorded. Analyses of transcriptions revealed that mothers and children indeed influenced each other's language. Bidirectional influence was observed for use of negative affect words: Mothers were more likely to use negative affect words if their child had just used negative affect words (over and above mothers' own language on their previous turn), and children were similarly influenced by mother affect word use. A similar bidirectional relation emerged for linguistic distance, a measure related to effective emotion regulation and mental health. However, the significance of the child-to-mother direction of influence for these two variables varied depending on correction threshold and should thus be verified in future research. Nonetheless, these findings extend understanding of emotional influence by showing turn-by-turn relations between the use of affective language.

BACKGROUND: Recent research implicates fibroblast growth factor 2 (FGF2) in anxiety and depressive symptoms of childhood. This study is the first to examine an intergenerational pathway linking FGF2 levels in mothers to FGF2 levels in children, and to the children's anxiety and depressive symptoms. METHODS: We assayed serum FGF2 in 259 mothers and their children, with a range of anxiety and depressive symptoms: 194 were mothers of clinic-referred anxious and depressed children; 65 were mothers of non-referred children. We examined associations between FGF2 levels in mothers and children, and anxiety and depression symptoms. We used structural equation modeling (SEM) to examine associations between maternal and child FGF2 levels, and between maternal and child FGF2 levels and symptoms of anxiety and depression in and children. RESULTS: FGF2 levels in mothers and children were significantly positively correlated. Children's FGF2 levels were significantly negatively correlated with their ratings of anxiety and depression. Results of the SEM model showed that increases in maternal FGF2 levels were significantly associated with increases in child FGF2, which in turn was associated with decreases in child anxiety and child depression, controlling for maternal anxiety and depression. LIMITATIONS: We relied on self-reported ratings of anxiety and depression, and on a single measurement of FGF2 levels for each participant. CONCLUSIONS: Our results point to a role for FGF2 in the intergenerational transmission of risk for, and resilience to, anxiety and depression in youth.

OBJECTIVE: Although cognitive behavioral treatments (CBTs) are well-established evidence-based interventions for anxiety disorders in youth, there is long-standing underrepresentation of Hispanic/Latino (H/L) families in youth anxiety clinical trials research. The impact of such underrepresentation is that clinicians who work with H/L youth have minimal evidence-based guidance on best practices. The present study moves toward informing best practices for working with H/L youth with anxiety disorders by examining H/L parents' acculturation and enculturation as moderators of youth anxiety outcomes following CBTs. METHOD: Two hundred eleven H/L youths ages 6-16 (M = 9.41 years, SD = 2.39 years; 43.8% female) and their parents were assigned to individual-youth CBT or one of two parent involvement CBTs: one targeted decreasing parent psychological control, the other targeted decreasing parent use of negative reinforcement. Parent acculturation and enculturation were measured at pretreatment; youth anxiety severity was measured at pretreatment, posttreatment, and 12-month follow-up evaluations. RESULTS: Youth anxiety outcomes were enhanced in both parent involvement CBTs compared with individual-youth CBT. Parent acculturation, but not enculturation, significantly moderated outcomes. At lower levels of parent acculturation, youth anxiety outcomes were enhanced in the parent involvement CBT that targeted negative reinforcement. At higher levels of parent acculturation, youth anxiety outcomes were enhanced in the parent involvement CBT that targeted psychological control. CONCLUSIONS: These findings further support the efficacy of CBTs for anxiety disorders in H/L youth and suggest guidance for tailoring parent involvement treatments based on parent acculturation levels.

Research has uncovered a wide range of predictors of youth anxiety treatment outcome (i.e., symptom severity and diagnostic remission). Youth's social functioning is one predictor that has been rarely studied, however, which is a significant gap given its importance to development and clinical functioning. We address this gap by examining two aspects of youth's social functioning as predictors of anxiety treatment outcome: (1) positive social interactions and (2) social skills. We further examined the moderating roles of treatment arm (child- or parent-based treatment), diagnosis (presence or absence of social anxiety disorder), and youth gender, between each of the two predictors and treatment response and remission. Participants were 96 youths with anxiety disorders (6-16 years; 54% girls) and their mothers, who completed diagnostic interviews and questionnaires at baseline and posttreatment. Multiple regression models revealed that higher baseline parent-reports of their child's social skills predicted lower posttreatment anxiety symptom severity for youth with social anxiety disorder. Modified linear probability models revealed that baseline youth-reports of their social skills predicted remission from anxiety diagnoses for youths assigned to the parent-based treatment. Baseline youth-reports of their positive social interactions and parent-reports of youth social skills predicted remission from anxiety diagnoses for girls. Results contribute to the predictor literature by highlighting the importance of youth social functioning to anxiety treatment outcome.

We conducted a dismantling design treatment study comparing individual CBT, CBT targeting parents' reinforcement skills (CBT+Reinf), and CBT targeting parents' relationship skills (CBT+ Relat) in 341 youths with primary anxiety diagnoses. At posttreatment, youths in CBTs with parent involvement had lower anxiety than youths in CBT. At 12-month follow-up, youths in CBT+Relat maintained lower anxiety relative to CBT. At posttreatment, negative reinforcement was significantly lower in CBT+Reinf than CBT+Relat and CBT; negative reinforcement partially mediated youth anxiety reduction. Reducing parental negative reinforcement in CBT+Reinf was associated with lower parental psychological control which also partially mediated youth anxiety reduction. Some of these mediational dynamics continued through follow-up. Targeting concrete behavioral parenting skills, especially negative reinforcement, produced treatment specificity and partial mediation relative to less concrete targeting, and enhanced CBT. Findings highlight complexities in identifying mechanisms through which targeting of parenting skills produces youth anxiety reduction and suggest avenues for future research.
ABSTRACT
BACKGROUND: We leveraged a recent efficacy trial to investigate directionality between parent anxiety and child anxiety at posttreatment and 12-month follow-up, and the potential role of parent psychological control as a mediator. We also explored child age and sex as moderators. METHOD: Two-hundred and fifty-four children were randomized to individual cognitive behavioral therapy (CBT) or to one of two CBT arms with parent involvement. Parent anxiety was not a treatment target in any of the three arms. RESULTS: Child anxiety at posttreatment was associated with parent anxiety and psychological control at 12-month follow-up, providing evidence of child-to-parent directionality. Parent anxiety at posttreatment was associated indirectly with child anxiety at 12-month follow-up through associations with parent psychological control, providing evidence of parent-to-child directionality. At posttreatment, parent psychological control contemporaneously mediated the relation between parent and child anxiety. Neither child age nor sex moderated any association. CONCLUSIONS: Findings highlight the directional effects between child anxiety, parent anxiety, and psychological control from posttreatment to 12-month follow-up, even when parent anxiety is not a treatment target. Research and clinical implications are discussed, with an emphasis on enhancing durability following treatment effects.

The Attentional Control Scale for Children (ACS-C) is a widely used self-report questionnaire that measures attentional control in youth. Previous research examined factor-structure and validation of the ACS-C and yielded a 2-factor structure with Attentional Focusing and Attentional Shifting subscales. This study used a confirmatory factor analysis in a large, ethnically diverse sample of clinic-referred anxious youth (N = 442, ages 7-16 years) to compare model fit of three models, the original two-factor model of the ACS-C, a two-factor model of a modified ACS-C (two items re-assigned from Attentional Focusing to Attentional Shifting, three items removed from Attentional Focusing, and two items removed from Attentional Shifting), and a single-factor model. Results reveal best model fit for the two-factor modified ACS-C. This model had strong factorial invariance across sex, partial invariance across ethnicity, and was variant across age. Also, total and subscale scores for the two-factor modified ACS-C correlated with anxiety and depression symptom scale scores, supporting its concurrent validity. Findings confirm the two-factor structure of the modified ACS-C. Future research implications relating to attentional control in children are discussed.

BACKGROUND: Research links fibroblast growth factor 2 (FGF2) to anxiety and depression in rodents and human adults. Our study is the first to examine FGF2 levels in a pediatric population. METHODS: We assayed serum FGF2 in 163 children with a broad range of anxiety and depressive symptoms; 111 were clinic-referred anxious and depressed children; 52 were non-referred children. We examined associations between FGF2 and anxiety and depression symptoms, and between each of the three facets of behavioral activation (Reward-Responsiveness, Drive, Fun-Seeking) and behavioral avoidance. We used confirmatory factor analysis (CFA) to determine the relative contribution of anxiety and depression indicators and of FGF2 to a latent variable of Anxiety/Depression. We also examined stability of FGF2 levels. RESULTS: FGF2 levels in clinic-referred children were significantly lower compared with non-referred children. Bivariate correlations and CFA showed negative associations between FGF2 and anxiety, depression and behavioral avoidance. FGF2 levels were positively correlated with the Reward-Responsiveness facet of behavioral activation, implicated in depression. FGF2 levels were stable over six months. LIMITATIONS: We did not have data on behavioral avoidance and stability of FGF2 in the entire sample. CONCLUSIONS: Our results implicate FGF2 in anxiety and depression in children, providing an important first step in showing FGF2 may serve as a stable biomarker for these prevalent and impairing problems.

There is frequently a presumption that Latino parents have a greater preference for involvement in their child's treatment for anxiety compared to non-Latino white parents. However, parent involvement may increase burdens associated with treatment and research suggests that Latino individuals already face significantly greater barriers to obtaining mental health treatment. In the current study, we compared Latino and non-Latino parents' preferences for parental involvement and perceptions of burdens in cognitive behavioral therapy (CBT) for youth anxiety. 117 parents (57 Latino) completed measures to assess child anxiety, perceptions of treatment involvement, and burdens associated with treatment. There were no significant differences between Latino and non-Latino parents except for a trend toward Latino parents reporting more concerns about the feasibility of obtaining CBT for their child's anxiety. Because Latino parents expressed concern about potential treatment barriers, cultural adaptations for treatment should focus on decreasing burdens associated with treatment rather than increasing parental involvement.

OBJECTIVE: Research on family accommodation is burgeoning, implicating it in the development, maintenance, and treatment of childhood anxiety. Additional data are needed to guide theory development and clinical application in this area. The factors underlying family accommodation measures have never been confirmed, nor have any test-retest data been reported. The study's objectives were to provide confirmatory data of the factorial structure and the first test-retest reliability data on the most widely used measure of family accommodation of child anxiety, the Family Accommodation Scale - Anxiety (FASA), and the child-rated FASA-CR. METHOD: Participants were 331 children (51% female; mean age = 10.44 yrs, SD = 2.95; 84.6% White) and their parent, presenting consecutively to an anxiety disorders program. Exploratory factor analysis (EFA) was conducted first on a random sampling of 105 child-parent dyads; factors were confirmed with confirmatory factor analysis (CFA) in the remaining independent sample of 226 dyads. Test-retest reliability (mean retest interval = 10 days) was examined for FASA and FASA-CR. Convergent validity was examined in relation to child anxiety symptoms, and parenting stress. Divergent validity was examined in relation to child depression symptoms. RESULTS: EFA and CFA supported a two-factor model of family accommodation, representing Participation in child-anxiety-driven behaviors, and child-anxiety-related Modification of family routines and schedules. Test-retest reliability was satisfactory for parents and adolescents; less so for children aged 6 to 12 years. CONCLUSIONS: Family accommodation is a key construct in childhood anxiety, with two underlying factors that can be validly and reliably assessed using FASA and FASA-CR.

Questionnaire measures offer a time and cost-effective alternative to full diagnostic assessments for identifying and differentiating between potential anxiety disorders and are commonly used in clinical practice. Little is known, however, about the capacity of questionnaire measures to detect specific anxiety disorders in clinically anxious preadolescent children. This study aimed to establish the ability of the Spence Children's Anxiety Scale (SCAS) subscales to identify children with specific anxiety disorders in a large clinic-referred sample (N = 1,438) of children aged 7 to 12 years. We examined the capacity of the Separation Anxiety, Social Phobia, Generalized Anxiety, and Physical Injury Fears (phobias) subscales to discriminate between children with and without the target disorder. We also identified optimal cutoff scores on subscales for accurate identification of children with the corresponding disorder, and examined the contribution of child, mother, and father reports. The Separation Anxiety subscale was able to accurately identify children with separation anxiety disorder, and this was replicated across all 3 reporters. Mother- and father-reported Social Phobia subscales also accurately identified children with social anxiety disorder, although child report was only able to accurately detect social anxiety disorder in girls. Using 2 or more reporters improved the sensitivity of the Separation Anxiety and Social Phobia subscales but reduced specificity. The Generalized Anxiety and Physical Injury Fears subscales failed to accurately identify children with the corresponding disorders. These findings have implications for the potential use of mother-, father-, and child-report SCAS subscales to detect specific disorders in preadolescent children in clinical settings.

OBJECTIVE: Treatment specificity and long-term recovery mediation of peer-involvement group cognitive behavioral therapy (GCBT) and parent-involvement CBT (PCBT) were investigated for youth anxiety disorders. METHOD: 240 youths with primary anxiety diagnoses participated in a randomized controlled efficacy trial. Youth anxiety and peer variables/mediators (positive peer-youth relationships; social skills), and parent variables/mediators (psychological control; negative parent-youth relationships) were assessed. RESULTS: At posttreatment and 12-month follow up, positive peer-youth relationships were significantly higher in GCBT than PCBT (specificity). At posttreatment, not follow up, parental psychological control was significantly lower in PCBT than GCBT (specificity). Parental psychological control and positive peer-youth relationships were putative mediators. The two CBTs produced similar anxiety reductions through different mechanisms. CONCLUSIONS: CBT targets show specificity and mediation, providing insight into specific mechanisms through which GCBT and PCBT bring about anxiety reduction and guidance for streamlining these CBTs in practice.
ABSTRACT
Cognitive behavioral therapies (CBTs) are efficacious treatments for anxiety disorders in Latino youth. However, there is a gap in knowledge about moderators of CBT outcomes in Latino youth. This study addresses this gap by examining parental acculturation as a moderator of youth anxiety outcomes in a randomized controlled trial of parent-involved CBT (CBT/P) and peer-involved group CBT (GCBT) in 139 Latino youth (ages 6 to 16 years; mean age = 9.68 years). Comparable youth anxiety reduction effects were found for CBT/P and GCBT. Parental acculturation to majority US culture, but not identification with country of origin, significantly moderated youth anxiety outcomes: at low levels of parental acculturation to majority US culture, youth posttreatment anxiety scores were lower in GCBT than CBT/P; at high levels of parental acculturation to majority US culture, youth posttreatment anxiety scores were lower in CBT/P than GCBT. These findings provide further evidence for the efficacy of CBTs for anxiety disorders in Latino youth and also provide guidance for moving toward personalization of CBTs' selection depending on parental acculturation levels.
ABSTRACT
Social media holds promise as a technology to facilitate social engagement, but may displace offline social activities. Adolescents with ASD are well suited to capitalize on the unique features of social media, which requires less decoding of complex social information. In this cross-sectional study, we assessed social media use, anxiety and friendship quality in 44 adolescents with ASD, and 56 clinical comparison controls. Social media use was significantly associated with high friendship quality in adolescents with ASD, which was moderated by the adolescents' anxiety levels. No associations were founds between social media use, anxiety and friendship quality in the controls. Social media may be a way for adolescents with ASD without significant anxiety to improve the quality of their friendships.

BACKGROUND: Anxiety disorders are common, and cognitive-behavioural therapy (CBT) is a first-line treatment. Candidate gene studies have suggested a genetic basis to treatment response, but findings have been inconsistent. AIMS: To perform the first genome-wide association study (GWAS) of psychological treatment response in children with anxiety disorders (n = 980). METHOD: Presence and severity of anxiety was assessed using semi-structured interview at baseline, on completion of treatment (post-treatment), and 3 to 12 months after treatment completion (follow-up). DNA was genotyped using the Illumina Human Core Exome-12v1.0 array. Linear mixed models were used to test associations between genetic variants and response (change in symptom severity) immediately post-treatment and at 6-month follow-up. RESULTS: No variants passed a genome-wide significance threshold (P = 5 × 10(-8)) in either analysis. Four variants met criteria for suggestive significance (P<5 × 10(-6)) in association with response post-treatment, and three variants in the 6-month follow-up analysis. CONCLUSIONS: This is the first genome-wide therapygenetic study. It suggests no common variants of very high effect underlie response to CBT. Future investigations should maximise power to detect single-variant and polygenic effects by using larger, more homogeneous cohorts.

A substantial number of children with anxiety disorders do not improve following cognitive behavioral therapy (CBT). Recent effectiveness studies have found poorer outcome for CBT programs than what is typically found in efficacy studies. The present study examined predictors of treatment outcome among 181 children (aged 8-15 years), with separation anxiety, social phobia, or generalized anxiety disorder, who participated in a randomized, controlled effectiveness trial of a 10-session CBT program in community clinics. Potential predictors included baseline demographic, child, and parent factors. Outcomes were as follows: a) remission from all inclusion anxiety disorders; b) remission from the primary anxiety disorder; and c) child- and parent-rated reduction of anxiety symptoms at post-treatment and at 1-year follow-up. The most consistent findings across outcome measures and informants were that child-rated anxiety symptoms, functional impairment, a primary diagnosis of social phobia or separation anxiety disorder, and parent internalizing symptoms predicted poorer outcome at post-treatment. Child-rated anxiety symptoms, lower family social class, lower pretreatment child motivation, and parent internalizing symptoms predicted poorer outcome at 1-year follow-up. These results suggest that anxious children with more severe problems, and children of parents with elevated internalizing symptom levels, may be in need of modified, additional, or alternative interventions to achieve a positive treatment outcome.
