RESUMO

BACKGROUND: Autism includes core symptoms affecting general and social development. Up to 60% of autistic adolescents experience co-occurring anxiety disorders negatively influencing educational, social, and general development together with quality of life. A manualised cognitive behavioural therapy (CBT) program 'Cool Kids - Autism Spectrum Adaptation (ASA)' has previously demonstrated efficacy in reducing anxiety in children with co-occurring autism. The current study investigates the feasibility of adapting this program for adolescents. METHODS: Fifteen autistic adolescents, aged 14-17 years, with co-occurring anxiety disorders were enrolled in the study. Outcome measures collected from both adolescents and parents pre-, post-treatment and at 3-month follow-up included participant evaluation of the program, scores from a semi-structured anxiety interview, and questionnaires on anxiety symptoms, life interference, and quality of life. RESULTS: 92% of the families who completed the program found it useful and would recommend it to other families in a similar situation. At follow-up, 55% no longer met the criteria for their primary anxiety diagnosis and 34% of adolescents were free of all anxiety diagnoses. Of the five adolescents who did not attend school before treatment three (60%) had returned to school after treatment. CONCLUSION: This study suggests that the adaptation of the program 'Cool Kids - ASA' into an adolescent version is feasible and has the potential to show good effects thus enhancing the possibility of education, development and independence in future life for this group. Larger RCTs studies are, however, needed to examine the efficacy of the adolescent version.

RESUMO

Online treatment delivery has the potential to increase access to evidence-based mental health care for children with anxiety disorders. Using a randomized controlled trial design, we evaluated the efficacy of Cool Kids Online, a family-based and therapist supported internet-delivered cognitive behavioral treatment (CBT) designed to target anxiety disorders in children. Ninety-five children aged 7-12 years with a DSM-5 anxiety disorder were randomly allocated to Cool Kids Online or a waitlist control. Children were assessed at baseline, week 11, and 6-months following treatment. Children in waitlist received treatment after week 11 and also completed assessments immediately and six months after treatment, allowing treatment maintenance to be evaluated for all children. Compared to waitlist, Cool Kids Online led to significantly greater remission of anxiety disorders (primary and all anxiety diagnoses) and greater reduction of caregiver-reported anxiety symptoms and interference at week 11. Child-reported anxiety symptoms and interference and child- and caregiver-reported depressive or externalizing symptoms did not differ significantly between conditions. Medium to large within-treatment effects were observed for all children from pre to post treatment with post treatment effects maintained until follow-up. Overall, the findings provide support for the efficacy of the program in treating anxiety. Cool Kids Online compared to waitlist for the remission of anxiety disorders in clinically anxious children; anzctr.org.au; ACTRN12615000947505.

RESUMO

BACKGROUND: Anxiety disorders are the most prevalent mental disorder in children and young people. Developing effective therapy for these children is critical to reduce mental disorders across the lifespan. The study aimed to evaluate the efficacy of combining cognitive behavioural therapy (CBT) and sertraline (SERT) in the treatment of anxiety in youth, using a double-blind randomised control trial design. METHODS: Ninety-nine youth (ages 7-15 years) with an anxiety disorder were randomly allocated to either individual (CBT) and SERT or individual CBT and pill placebo and assessed again immediately and 6 months after treatment. RESULTS: There were no significant differences between conditions in remission of primary anxiety disorder or all anxiety disorders. Furthermore, there were no significant differences in rates of change in diagnostic severity, parent-reported anxiety symptoms, child-reported anxiety symptoms or life interference due to anxiety. CONCLUSIONS: The efficacy of CBT for children and adolescents with anxiety disorders is not significantly enhanced by combination with a short-term course of anti-depressants over and above the combined effects of pill placebo.

RESUMO

Methods to deliver empirically validated treatments for anxious youth that require fewer therapist resources (low intensity) are beginning to emerge. However, the relative efficacy of low-intensity treatment for youth anxiety against standard face-to-face delivery has not been comprehensively evaluated. Young people aged 6-16 years with a primary anxiety disorder (N = 281) were randomly allocated to treatment delivered either face-to-face or in a low-intensity format. Face-to-face treatment comprised ten, 60-min sessions delivered by a qualified therapist. Low intensity comprised information delivered in either printed (to parents of children under 13) or electronic (to adolescents aged 13 +) format and was supported by up to four telephone sessions with a minimally qualified therapist. Youth receiving face-to-face treatment were significantly more likely to remit from all anxiety disorders (66%) than youth receiving low intensity (49%). This difference was reflected in parents' (but not child) reports of child's anxiety symptoms and life interference. No significant moderators were identified. Low intensity delivery utilised significantly less total therapist time (175 min) than face-to-face delivery (897 min) and this was reflected in a large mean difference in therapy costs ($A735). Standard, face-to-face treatment for anxious youth is associated with significantly better outcomes than delivery of similar content using low-intensity methods. However, the size of this difference was relatively small. In contrast, low-intensity delivery requires markedly less time from therapists and subsequently lower treatment cost. Data provide valuable information for youth anxiety services.Clinical trial registration information: A randomised controlled trial of standard care versus stepped care for children and adolescents with anxiety disorders; https://anzctr.org.au/ ; ACTRN12612000351819.

RESUMO

This study developed an online diagnostic tool for anxiety disorders in youth, and evaluated its reliability and validity amongst 297 children aged 6-16 years (Mage = 9.34, 46% male). Parents completed the online tool, the Youth Online Diagnostic Assessment (YODA), which is scored either using a fully-automated algorithm, or combined with clinician review. In addition, parents and children completed a clinician-administered diagnostic interview and self-report measures of internalizing and externalizing symptoms and wellbeing. The fully-automated YODA demonstrated relatively weak agreement with the diagnostic interview for identifying the presence of any anxiety disorder and specific anxiety disorders, apart from separation anxiety (which had moderate agreement). The clinician-reviewed YODA showed better agreement than fully-automated scoring, particularly for identifying the presence of any anxiety disorder. The YODA demonstrated good agreement with parent-reported measures of symptoms/interference. The YODA offers a fully or largely automated method to determine the presence of anxiety disorders in youth, with particular value in situations where low-resource assessments are needed. While it currently requires further research and improvement, the YODA provides a promising start to the development of such a tool.

RESUMO

OBJECTIVE: This study examined measurement variance for Autism Spectrum Disorder (ASD) in the Spence Children's Anxiety Scale - Parent Form (SCAS-P; Spence, 1999). In addition, we developed and evaluated a new parent report measure for anxiety (Macquarie Anxiety Behavioural Scale; MABS). METHOD: The sample consisted of 734 parents of children aged 3-19 years (i) who were seeking help for their child's anxiety, (ii) who had received a diagnosis of ASD, or (iii) from the community. RESULTS: Evidence for measurement variance of the SCAS-P and MABS was found, revealing different factor structures between the ASD and non-ASD groups. MIMIC modelling showed that the scales performed significantly different across ASD and non-ASD groups. Differential item functioning on a number of the SCAS-P and MABS items was also found. LIMITATIONS: This study relied on parent report of symptoms and of community acquired diagnoses of ASD. CONCLUSION: The MABS is a new parent measure to assess anxiety in children and adolescents and the proposed factor structure produced a reasonably good fit for the data. Similar to the SCAS-P, ASD was found to impact on some of the MABS items indicating that ASD influences parental responding. Eighteen MABS items showed measurement invariance across the anxious and ASD groups and can be considered suitable items for the assessment of anxiety in ASD.

RESUMO

OBJECTIVE: The present study assessed the utility of the Spence Children's Anxiety Scale - Parent Form (SCAS-P) across parents of children with (i) anxiety and (ii) Autism Spectrum Disorder (ASD). METHOD: Parents of children aged 7-18 years with anxiety or ASD completed the SCAS-P. Multiple indicator multiple cause (MIMIC) structural equation modelling was utilized to analyse the data. RESULTS: Analysis revealed different factor structures between the Anxious and ASD groups and evidence for measurement variance across groups in some parts of the SCAS-P. CONCLUSION: Results on the SCAS-P in children with ASD need to be interpreted with caution. Some SCAS-P items cannot be interpreted in the same way in an ASD population compared to neurotypical children with anxiety.

RESUMO

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.

RESUMO

BACKGROUND: Stepped care has been promoted for the management of mental disorders; however, there is no empirical evidence to support the cost-effectiveness of this approach for the treatment of anxiety disorders in youth. METHOD: This economic evaluation was conducted within a randomised controlled trial comparing stepped care to a validated, manualised treatment in 281 young people, aged 7-17, with a diagnosed anxiety disorder. Intervention costs were determined from therapist records. Administrative data on medication and medical service use were used to determine additional health care costs during the study period. Parents also completed a resource use questionnaire to collect medications, services not captured in administrative data and parental lost productivity. Outcomes included participant-completed quality of life, Child Health Utility - nine-dimension and parent-completed Assessment of Quality of Life - eight-dimension to calculate quality-adjusted life years. Mean costs and quality-adjusted life years were compared between groups at 12-month follow-up. RESULTS: Intervention delivery costs were significantly less for stepped care from the societal perspective (mean difference -$198, 95% confidence interval -$353 to -$19). Total combined costs were less for stepped care from both societal (-$1334, 95% confidence interval -$2386 to $510) and health sector (-$563, 95% confidence interval -$1353 to $643) perspectives but did not differ significantly from the manualised treatment. Youth and parental quality-adjusted life years were not significantly different between groups. Sensitivity analysis indicated that the results were robust. CONCLUSION: For youth with anxiety, this three-step model provided comparable outcomes and total health sector costs to a validated face-to-face programme. However, it was less costly to deliver from a societal perspective, making it an attractive option for some parents. Future economic evaluations comparing various models of stepped care to treatment as usual are recommended.

RESUMO

BACKGROUND: The Online Assessment of Preschool Anxiety (OAPA) is a newly developed measure that assesses anxiety disorders in preschool children aged 3-6 years. This study aimed to explore the OAPA's initial psychometric properties with a particular focus on examining its construct validity, both convergent and discriminant. METHOD: The OAPA was completed online by a community sample of 319 Australian parents of temperamentally inhibited preschool children (M: 5.3 years). Preliminary diagnoses were automatically generated before assessment reports were reviewed by a psychologist. Construct validity was examined by assessing the degree of agreement between the OAPA and existing valid questionnaire measures that were simultaneously administered online. RESULTS: Nearly half of participants met criteria for a child anxiety disorder according to the OAPA, most commonly social phobia. Findings supported convergent validity with the Revised Preschool Anxiety Scale (an anxiety symptom measure), the Children's Anxiety Life Interference Scale - Preschool Version (a measure of life interference from anxiety), the Emotional Symptoms scale of the Strengths and Difficulties Questionnaire-Parent Version (a measure of broader internalizing symptoms), as well as an over-involved/protective parenting scale. Findings also supported initial discriminant validity with the Conduct Problems scale of the Strengths and Difficulties Questionnaire-Parent Version. CONCLUSIONS: Results of this study provide evidence for the OAPA's preliminary construct validity. With further research into the OAPA's reliability (test-retest and interrater) and confirming construct validity, the OAPA may be a useful instrument for use in research settings and clinical practice.

RESUMO

OBJECTIVE: To determine whether comorbid attention-deficit/hyperactivity disorder (ADHD) diagnosis (including subtype) predicts response to cognitive-behavior therapy (CBT) for anxiety in children and to examine change in ADHD symptoms after treatment of primary anxiety. METHOD: A sample of 842 children 5 to 18 years of age received CBT for a primary anxiety disorder. A subsample of 94 children met criteria for comorbid mild-to-moderate ADHD, mostly consisting of predominantly inattentive (n = 61) and combined (n = 27) subtypes. Outcome was defined as response (change in diagnostic severity) and remission (absence of the primary diagnosis) at each time point (after treatment and 3- and/or 6-month follow-up) and analyzed using linear and logistic mixed models. RESULTS: Neither ADHD diagnosis nor subtype predicted response or remission rates for children's primary anxiety disorders. Children with ADHD also showed modest yet significant improvements in ADHD symptoms after CBT for anxiety. CONCLUSION: The present findings support the suitability of manual-based group-based CBT for anxiety treatment in children with nonprimary ADHD. Further research should examine whether the positive outcomes reported can be extended to children with primary or severe ADHD.

RESUMO

BACKGROUND: Several delivery formats of cognitive behaviour therapy (CBT) for child anxiety have been proposed, however, there is little consensus on the optimal delivery format. The primary goal of this study was to investigate the impact of the child's primary anxiety diagnosis on changes in clinical severity (of the primary problem) during individual CBT, group CBT and guided parent-led CBT. The secondary goal was to investigate the impact of the child's primary anxiety diagnosis on rates of remission for the three treatment formats. METHODS: A sample of 1,253 children (5-12 years; Mage = 9.3, SD = 1.7) was pooled from CBT trials carried out at 10 sites. Children had a primary diagnosis of generalised anxiety disorder (GAD), social anxiety disorder (SoAD), specific phobia (SP) or separation anxiety disorder (SAD). Children and parents completed a semistructured clinical interview to assess the presence and severity of DSM-IV psychiatric disorders at preintervention, postintervention and follow-up. Linear mixture modelling was used to evaluate the primary research question and logistic modelling was used to investigate the secondary research question. RESULTS: In children with primary GAD, SAD or SoAD, there were no significant differences between delivery formats. However, children with primary SP showed significantly larger reductions in clinical severity following individual CBT compared to group CBT and guided parent-led CBT. The results were mirrored in the analysis of remission responses with the exception that individual CBT was no longer superior to group CBT for children with a primary SP. The difference between individual and group was not significant when follow-up data were examined separately. CONCLUSIONS: Data show there may be greater clinical benefit by allocating children with a primary SP to individual CBT, although future research on cost-effectiveness is needed to determine whether the additional clinical benefits justify the additional resources required.

RESUMO

Despite growing recognition of childhood anxiety as a common and often debilitating clinical concern, we have limited knowledge of the particular ways in which anxiety interferes with daily life for young children who have not yet entered formal schooling. The present study evaluated the psychometric properties of the Child Anxiety Life Interference Scale - Preschool Version (CALIS-PV). The CALIS-PV is a brief (18 item) parent-report measure of the impacts of a young child's anxiety on their own life and that of her or his parent. Participants were 784 parents of a child aged 3-7 years, who completed the CALIS-PV as a part of the follow-up assessment battery for two anxiety prevention trials targeted at preschool children with temperamental inhibition. Confirmatory factor analysis supported three CALIS-PV factors reflecting anxiety-related life interference at home, outside home and on parent life. The three factors showed good internal consistency and good convergent and divergent validity, and successfully differentiated children with and without an anxiety diagnosis. Findings provide initial support for the CALIS-PV as a reliable and valid measure of the daily life impacts of childhood anxiety for preschool-aged children and their parents.

RESUMO

OBJECTIVE: Stepped care is embraced as an ideal model of service delivery but is minimally evaluated. The aim of this study was to evaluate the efficacy of cognitive-behavioral therapy (CBT) for child anxiety delivered via a stepped-care framework compared against a single, empirically validated program. METHOD: A total of 281 youth with anxiety disorders (6-17 years of age) were randomly allocated to receive either empirically validated treatment or stepped care involving the following: (1) low intensity; (2) standard CBT; and (3) individually tailored treatment. Therapist qualifications increased at each step. RESULTS: Interventions did not differ significantly on any outcome measures. Total therapist time per child was significantly shorter to deliver stepped care (774 minutes) compared with best practice (897 minutes). Within stepped care, the first 2 steps returned the strongest treatment gains. CONCLUSION: Stepped care and a single empirically validated program for youth with anxiety produced similar efficacy, but stepped care required slightly less therapist time. Restricting stepped care to only steps 1 and 2 would have led to considerable time saving with modest loss in efficacy.

RESUMO

Use of the partial NMDA receptor agonist d-Cycloserine (DCS) to increase extinction to feared cues among anxious adults has shown mixed, although overall positive effects. Few studies have extended this effect to youth and none have addressed young people with broad-based anxiety such as separation anxiety, social anxiety, or generalised anxiety. In the current trial 51 children and adolescents with diagnosed anxiety disorders, aged 7-14 years received four sessions of graduated, experimenter-led, in vivo exposure to a hierarchy of feared cues relevant to their primary fear. They were randomly allocated to receive either 50 mg of DCS or a matched placebo capsule in a fully double-blind design. Both groups showed large reductions across sessions in their primary fear according to both parent and child report, but there were no significant differences between conditions at any session. The results are consistent with most studies to date of DCS-augmented exposure in young people.

RESUMO

PURPOSE: Stuttering during adulthood is associated with a heightened rate of anxiety disorders, especially social anxiety disorder. Given the early onset of both anxiety and stuttering, this comorbidity could be present among stuttering children. METHOD: Participants were 75 stuttering children 7-12 years and 150 matched non-stuttering control children. Multinomial and binary logistic regression models were used to estimate odds ratios for anxiety disorders, and two-sample t-tests compared scores on measures of anxiety and psycho-social difficulties. RESULTS: Compared to non-stuttering controls, the stuttering group had six-fold increased odds for social anxiety disorder, seven-fold increased odds for subclinical generalized anxiety disorder, and four-fold increased odds for any anxiety disorder. CONCLUSION: These results show that, as is the case during adulthood, stuttering during childhood is associated with a significantly heightened rate of anxiety disorders. Future research is needed to determine the impact of those disorders on speech treatment outcomes.

RESUMO

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.

RESUMO

BACKGROUND: We previously reported an association between 5HTTLPR genotype and outcome following cognitive-behavioural therapy (CBT) in child anxiety (Cohort 1). Children homozygous for the low-expression short-allele showed more positive outcomes. Other similar studies have produced mixed results, with most reporting no association between genotype and CBT outcome. AIMS: To replicate the association between 5HTTLPR and CBT outcome in child anxiety from the Genes for Treatment study (GxT Cohort 2, n = 829). METHOD: Logistic and linear mixed effects models were used to examine the relationship between 5HTTLPR and CBT outcomes. Mega-analyses using both cohorts were performed. RESULTS: There was no significant effect of 5HTTLPR on CBT outcomes in Cohort 2. Mega-analyses identified a significant association between 5HTTLPR and remission from all anxiety disorders at follow-up (odds ratio 0.45, P = 0.014), but not primary anxiety disorder outcomes. CONCLUSIONS: The association between 5HTTLPR genotype and CBT outcome did not replicate. Short-allele homozygotes showed more positive treatment outcomes, but with small, non-significant effects. Future studies would benefit from utilising whole genome approaches and large, homogenous samples.

RESUMO

BACKGROUND: Hypothalamic-pituitary-adrenal (HPA) axis functioning has been implicated in the development of stress-related psychiatric diagnoses and response to adverse life experiences. This study aimed to investigate the association between genetic and epigenetics in HPA axis and response to cognitive behavior therapy (CBT). METHODS: Children with anxiety disorders were recruited into the Genes for Treatment project (GxT, N = 1,152). Polymorphisms of FKBP5 and GR were analyzed for association with response to CBT. Percentage DNA methylation at the FKBP5 and GR promoter regions was measured before and after CBT in a subset (n = 98). Linear mixed effect models were used to investigate the relationship between genotype, DNA methylation, and change in primary anxiety disorder severity (treatment response). RESULTS: Treatment response was not associated with FKBP5 and GR polymorphisms, or pretreatment percentage DNA methylation. However, change in FKBP5 DNA methylation was nominally significantly associated with treatment response. Participants who demonstrated the greatest reduction in severity decreased in percentage DNA methylation during treatment, whereas those with little/no reduction in severity increased in percentage DNA methylation. This effect was driven by those with one or more FKBP5 risk alleles, with no association seen in those with no FKBP5 risk alleles. No significant association was found between GR methylation and response. CONCLUSIONS: Allele-specific change in FKBP5 methylation was associated with treatment response. This is the largest study to date investigating the role of HPA axis related genes in response to a psychological therapy. Furthermore, this is the first study to demonstrate that DNA methylation changes may be associated with response to psychological therapies in a genotype-dependent manner.

RESUMO

The present study was designed to examine the effects of training in positive interpretations in clinically anxious children. A total of 87 children between 7 and 12 years of age were randomly assigned to either a positive cognitive bias modification training for interpretation (CMB-I) or a neutral training. Training included 15 sessions in a two-week period. Children with an interpretation bias prior to training in the positive training group showed a significant reduction in interpretation bias on the social threat scenarios after training, but not children in the neutral training group. No effects on interpretation biases were found for the general threat scenarios or the non-threat scenarios. Furthermore, children in the positive training did not self-report lower anxiety than children in the neutral training group. However, mothers and fathers reported a significant reduction in social anxiety in their children after positive training, but not after neutral training. This study demonstrated that clinically anxious children with a prior interpretation bias can be trained away from negative social interpretation biases and there is some evidence that this corresponds to reductions in social anxiety. This study also highlights the importance of using specific training stimuli.
