Treatment of childhood anxiety disorder in the context of maternal anxiety disorder: a randomised controlled trial and economic analysis

A Systematic Review of Methods Used by Pediatric Cost-Utility Analyses to Include Family Spillover Effects

BACKGROUND

A child's health condition affects family members' health and well-being. However, pediatric cost-utility analysis (CUA) commonly ignores these family spillover effects leading to an incomplete understanding of the cost and benefits of a child's health intervention. Methodological challenges exist in assessing, valuing, and incorporating family spillover effects.

OBJECTIVE

This study systematically reviews and compare methods used to include family spillover effects in pediatric CUAs.

METHODS

A literature search was conducted in MEDLINE, Embase, EconLit, Cochrane collection, CINAHL, INAHTA, and the Pediatric Economic Database Evaluation (PEDE) database from inception to 2020 to identify pediatric CUAs that included family spillover effects. The search was updated to 2021 using PEDE. The data describing in which family members spillover effects were measured, and how family spillover effects were measured, incorporated, and reported, were extracted. Common approaches were grouped conceptually. Further, this review identified theories or theoretical frameworks used to justify approaches for integrating family spillover effects into CUA.

RESULTS

Of 878 pediatric CUAs identified, 35 included family spillover effects. Most pediatric CUAs considered family spillover effects on one family member. Pediatric CUAs reported eight different approaches to measure the family spillover effects. The most common method was measuring the quality-adjusted life years (QALY) loss of the caregiver(s) or parent(s) due to a child's illness or disability using an isolated approach whereby family spillover effects were quantified in individual family members separately from other health effects. Studies used four approaches to integrate family spillover effects into CUA. The most common method was to sum children's and parents/caregivers' QALYs. Only two studies used a theoretical framework for incorporation of family spillover effects.

CONCLUSIONS

Few pediatric CUAs included family spillover effects and the observed variation indicated no consensus among researchers on how family spillover effects should be measured and incorporated. This heterogeneity is mirrored by a lack of practical guidelines by Health Technology Assessment (HTA) agencies or a theoretical foundation for including family spillover effects in pediatric CUA. The results from this review may encourage researchers to develop a theoretical framework and HTA agencies to develop guidelines for including family spillover effects. Such guidance may lead to more rigorous and standardized methods for including family spillover effects and better-quality evidence to inform decision-makers on the cost-effectiveness of pediatric health interventions.

Increasing the Efficacy of Treatment for Socially Anxious Youth Through Theoretically Derived Improvements: A Pilot Study

Cognitive behavioural therapy is the first line of treatment for social anxiety disorder; however, children with social anxiety disorder do not respond as well to generic cognitive behavioural therapy programs, compared to children with other anxiety disorders. The aim of the study was to provide a preliminary examination of the efficacy and applicability of a new disorder specific intervention for children with social anxiety disorder. Five children aged 7-13 years, with a primary or secondary DSM-5 diagnosis of social anxiety disorder were provided with an adapted version of the Cool Kids anxiety program. Three out of the five children were in remission from social anxiety disorder at the end of the intervention and at 3-month follow-up. Statistically significant improvements were also noted in overall anxiety symptoms and functioning. Preliminary evidence was found for the efficacy of a social anxiety version of the Cool Kids program.

Development and evaluation of a data-driven integrated management app for perioperative adverse events: protocol for a mixed-design study

INTRODUCTION

A patient record review study conducted in 2006 in a random sample of 21 Dutch hospitals found that 51%-77% of adverse events are related to perioperative care, while Centers for Disease Control and Prevention data in USA in 2013 estimated that the medical error is the third-leading cause of mortality. To capitalise on the potential of apps to enhance perioperative medical quality, there is a need for interventions developed in consultation with real-world users designed to support integrated management for perioperative adverse events (PAEs). This study aims: (1) to access the knowledge, attitude and practices for PAEs among physicians, nurses and administrators, and to identify the needs of healthcare providers for a mobile-based PAEs tool; (2) to develop a data-driven app for integrated PAE management that meets those needs and (3) to test the usability, clinical efficacy and cost-effectiveness of the developed app.

METHODS AND ANALYSIS

We will adopt an embedded mixed-methods research technique; qualitative data will be used to assess user needs and app adoption, while quantitative data will provide crucial insights to establish the demand for the app, and measure the app effects. Phase 1 will enrol surgery-related healthcare providers from the West China Hospital and identify their latent demand for mobile-based PAEs management using a self-designed questionnaire underpinned by the knowledge, attitude and practice model, as well as expert interviews. In phase 2, we will develop the app for integrated PAE management and test its effectiveness and sustainability. In phase 3, the effects on the total number and severity of reported PAEs will be evaluated using Poisson regression with interrupted time-series analysis over a 2-year period, while users' engagement, adherence, process evaluation and cost-effectiveness will be evaluated using quarterly surveys and interviews.

ETHICS AND DISSEMINATION

The West China Hospital of Sichuan University's Institutional Review Board authorised this study after approving the study protocol, permission forms and questionnaires (number: 2022-1364). Participants will be provided with study information, and informed written consent will be obtained. Study findings will be disseminated through peer-reviewed publications and conference presentations.

Preventing anxiety in the children of anxious parents - feasibility of a brief, online, group intervention for parents of one- to three-year-olds

BACKGROUND

The evidence suggests an increased risk of developing anxiety problems in children of anxious parents. The current study explored the feasibility and acceptability of an intervention with anxious parents of young children, to inform the possibility of further trials.

METHODS

Participants were recruited through primary and secondary care psychological services and social media. Participants who had a current or recent anxiety disorder and a child aged 12-47 months were included. Assessments of parental and child outcomes occurred at baseline, after the intervention (week-2) and follow-up (week-8). The intervention was delivered in a small group format, in two sessions, one week apart, using videoconferencing.

RESULTS

Out of 32 participants, 30 (94%) attended the full intervention. All found the intervention acceptable and reported it as useful and relevant. There was a reduction in parental depression (MD = 2.63, 95%CI 1.01-4.26), anxiety (MD = 3.93, 95%CI 2.49-5.37) and stress (MD = 4.60, 95% CI 3.02-6.18) and increases in parenting confidence.

CONCLUSIONS

The online group intervention was feasible and acceptable. There were moderate to large effects on parental mental health and no adverse effects on children (decline on outcome measures). This indicates that intervening early in parenting with anxious parents is possible and warrants further investigation to establish prevention efficacy with a larger, controlled trial.

Systematic Review of Cost-Utility Analyses That Have Included Carer and Family Member Health-Related Quality of Life

OBJECTIVES

Health interventions for patients can also affect the health of their informal carers and family members. These changes in carer or family member health could be reflected in cost-utility analyses (CUAs) through the inclusion of their quality-adjusted life-years (QALYs). We conducted a systematic review to identify and describe all CUAs that have included family member health-related QALYs.

METHODS

A total of 4 bibliographic databases were searched from inception to July 2021. A 2-stage sifting process for inclusion of studies was undertaken. We performed data extraction using a standardized data extraction form and performed a narrative synthesis of the evidence.

RESULTS

A total of 40 CUAs published between 1999 and 2021 were identified. CUAs were conducted in 15 different countries. CUAs examined 13 different conditions including 15 CUAs on vaccination, 5 on Alzheimer's disease, 2 on Parkinson's disease, 3 on dementia, and 2 on terminal illness. The EQ-5D was the most commonly used measure of family member health. Generally, including carer QALYs resulted in lower incremental cost-effectiveness ratios.

CONCLUSIONS

When considering the total number of economic evaluations published, few have included family member QALYs and the methods for doing so are often inconsistent and data sources often limited. Estimation of family member QALYs in patient CUAs was regularly uncertain and often substantial in magnitude. The findings highlight the variation among methods and call for greater consistency in methods for incorporating family member QALYs in patient CUAs.

Intervention cost-effectiveness for pediatric anxiety and OCD: A systematic review and integrated database model

BACKGROUND

While multiple treatments for pediatric anxiety and obsessive compulsive disorder (OCD) are efficacious, little is known about their cost-effectiveness. In response, we sought to provide relevant information through systematic review and cost-effectiveness simulation.

METHODS

We evaluated the cost-effectiveness of treatment for pediatric anxiety and OCD in two ways. First, we conducted a systematic review following PRISMA guidelines. Second, we evaluated cost-effectiveness for antidepressant medication, cognitive behavioral therapy, and their combination via a simulation that integrated information from the Truven MarketScan database and the NIMH National Database for Clinical Trials Related to Mental Illness.

RESULTS

Both systematic review and simulation found antidepressant medication and cognitive behavioral therapy to be cost-effective for pediatric anxiety and OCD. Antidepressant medication was the least costly approach, and cognitive behavioral therapy provided additional cost-effectiveness, especially for OCD.

LIMITATIONS

During systematic review, relatively few articles provided information about both costs and effectiveness. While there was a notable margin of error to support multiple interventions as cost-effective, limited prior research decreased precision of point estimates and comparisons between interventions.

CONCLUSIONS

Both antidepressant medication and cognitive behavioral therapy were found to be cost-effective for pediatric anxiety and OCD. Results supported investment from third party payers, who serve as critical gatekeepers that can increase treatment dissemination. However, more precise information would better inform the exact amount of investment needed, especially with regard to selection decisions between active interventions. Cost-effectiveness research would benefit from systematic collection of data on treatment costs and quality of life in future clinical trials.

A drop-in centre for treating mental health problems in children with chronic illness: Outcomes for parents and their relationship with child outcomes

Background

Children with chronic health conditions and their parents are at greater risk of developing emotional and behavioural problems compared to their physically healthy peers. The psychological impact on parents is crucial to understand given the relationship between parental mental health and child emotional and behavioural difficulties. This study was part of a broader research project examining the acceptability, feasibility and impact of a 'Mental Health and Psychological Wellbeing Drop-in Centre' in a paediatric hospital providing access to support and intervention for children and their families. This paper aimed to investigate the impact of the centre on parents (n = 148).

Methods

Parental anxiety and depression were assessed using the GAD-7 and PHQ-9 at baseline and 6-month post-baseline. Child mental health was assessed using the parent-report Strengths and Difficulties Questionnaire (SDQ). If parents had significant mental health needs, a brief intervention/signposting to relevant services was provided.

Results

At baseline, 48% of parents scored above clinical threshold for anxiety and 41% for depression, and parent reported child SDQ scores were correlated with parental anxiety and parental low mood. Self-reported parental anxiety and low mood decreased at 6-months post-baseline (parental anxiety: mean decrease = 2.29 [1.22-3.36], d = 0.38; parental low mood: mean decrease = 1.81 [0.64-3.00], d = 0.28). There were no significant correlations between change in parent reported child wellbeing and changes in parental low mood and anxiety between baseline and 6-month post-baseline.

Conclusions

Assessing and providing a brief treatment to address the mental health needs of parents of children with comorbidity may bring important benefits. It is recommended that children's mental health services consider assessment of parental mental health as part of routine care.

A Meta-analysis to Guide the Enhancement of CBT for Childhood Anxiety: Exposure Over Anxiety Management

Cognitive behavior therapy (CBT) is the most empirically supported therapy for childhood anxiety disorders (CADs) but has not reliably outperformed other credible interventions. The current study used meta-analysis to examine the frequency with which the most common treatment components are included in outcome studies and the relation of these components to symptom improvement. Seventy-five studies were identified that included youth with an anxiety disorder treated with CBT or a comparison condition. The protocols for the 111 CBT conditions generally consisted of 12, 1-h sessions delivered to the child with minimal parent inclusion. A greater amount of in-session exposure was related to significantly larger effect sizes between CBT and waitlist control across reporters (- 0.12 to - 0.15; P's < .05) and from pre- to post-treatment for child report (- .06; P < .01). Compared to treatments that omitted relaxation, treatments that included relaxation strategies were associated with significantly smaller pre- to post-treatment effect sizes across reporters (0.38 to 0.80; P's < .05). The current study suggests that CBT protocols for CADs that emphasize in-session exposure and do not include relaxation have the potential to improve the efficacy and effectiveness of therapy. Dismantling studies directly testing these hypotheses are needed.

Family Intervention for Child and Adolescent Anxiety: A Meta-analytic Review of Therapy Targets, Techniques, and Outcomes

Parent- and family-level correlates of youth anxiety are well-documented, and they highlight potential targets for family-focused intervention. Although family-based approaches for treating youth anxiety generally are considered efficacious for achieving symptom reduction, they vary in format and approach and it remains unclear whether they offer an advantage over individual child treatment. To better understand the current state of the evidence, we used meta-analytic methods to examine the therapeutic approaches described in existing family interventions for child and adolescent anxiety, whether they mapped to the major mechanisms proposed in the literature, and the timeline along which relevant parent/family variables were measured. We examined how these mechanism-focused family interventions performed in RCTs relative to individual child CBT and whether they shifted symptoms and relevant parenting behaviors. A total of 11 randomized controlled trials (RCTs) compared individual cognitive behavior therapy (CBT) to CBT+ a family component (CBT + FAM) and included a youth anxiety measure at pre- and post-treatment; only half of these (n=6) also included a parent/family functioning measure at both pre- and post-treatment (across both primary and secondary outcome papers). Only a single study included anxiety measures at a mid-treatment time point, and none included parent measures at a mid-treatment time point. Findings are discussed in terms of design considerations and advancing the field of family intervention for youth anxiety.

Effectiveness of cognitive behavioral therapy (CBT) for child and adolescent anxiety disorders across different CBT modalities and comparisons: a systematic review and meta-analysis

Aim: Pediatric Anxiety Disorders (AD) are common. Cognitive behavioral therapy (CBT) is one of two first-line treatments of youth AD and it has previously been shown to be superior to wait-list but not placebo therapy. This study consists of a systematic review and meta-analysis of the literature to assess the efficacy of CBT modalities in comparison to control contingencies for pediatric anxiety disorders.Methods: Studies were included if they were randomized controlled trials, and if CBT was manualized or modular, alone or in combination with medication. CBT was required to include behavioral treatment, exposure treatment, or cognitive elements. Eligible studies included participants aged 18 years or younger.Results: Eighty-one studies were included, with 3386 CBT participants and 2527 control participants. The overall results indicated that CBT is an effective treatment for childhood AD. The results showed that individual-based CBT is superior to wait-list and attention control. Group-based CBT is superior to wait-list control and treatment as usual. Remote-based CBT was superior to attention control and wait-list control. Family-based CBT was superior to treatment as usual, wait-list control, and attention control. Selective serotonin reuptake inhibitors were no more effective than individual-based CBT. Combination treatment was, however, more effective than individual-based CBT.Conclusion: To the best of our knowledge, no meta-analysis has thus far disentangled the effects of CBT modalities across various comparisons. This meta-analysis hence provides an important update to the literature on the efficacy of CBT for treating anxiety disorders in young people.

Identifying children with anxiety disorders using brief versions of the Spence Children's Anxiety Scale for children, parents, and teachers

Anxiety disorders are among the most prevalent mental health disorders experienced by children and are associated with significant negative outcomes. Only a minority of affected children, however, access professional help, and a failure to identify children with anxiety disorders presents a key barrier to treatment access. Existing child anxiety questionnaire measures are long and time consuming to complete, limiting their potential for widespread use as identification tools in community settings. We developed a brief questionnaire for parents, children, and teachers using items from the Spence Children’s Anxiety Scale (SCAS) and evaluated the new measure’s psychometric properties, capacity to discriminate between a community (n = 361) and clinic-referred sample (n = 338) of children aged 7–11, and identified optimal cut-off scores for accurate identification of preadolescent children experiencing clinically significant levels of anxiety. The findings provided support for the reliability and validity of 8-item versions of the SCAS, with the brief questionnaire scores displaying comparable internal consistency, agreement among reporters, and convergent/divergent validity to the full-length SCAS scores. The brief SCAS scores also discriminated between the community and clinic-referred samples and identified children in the clinic-referred sample with a moderate-to-good level of accuracy and acceptable sensitivity and specificity. Combining reporters improved sensitivity, but at the expense of specificity, and findings suggested parent report should be prioritized. This new brief questionnaire has potential for use in community settings as a tool to improve identification of children who are experiencing clinically significant levels of anxiety and warrant further assessment and potential support.

We developed and evaluated brief versions of the Spence Children’s Anxiety Scale for parents, children, and teachers. Results provide support for the potential application of this new brief questionnaire in community settings to improve identification of children with anxiety disorders.

Family income, maternal psychological distress and child socio-emotional behaviour: Longitudinal findings from the UK Millennium Cohort Study

The association between low family income and socio-emotional behaviour problems in early childhood has been well-documented, and maternal psychological distress is highlighted as central in mediating this relationship. However, whether this relationship holds for older children, and the precise mechanisms by which income may influence child behaviour is unclear. This study investigated the relationship between family income and child socio-emotional behaviour at 11 years of age, and examined the mediating role of maternal psychological distress over time using the UK Millennium Cohort Study. The primary outcome was parent-reported behavioural problems, as captured by the Total Difficulties Score (TDS), derived from the Strengths and Difficulties Questionnaire (SDQ). Secondary outcomes were the emotional, peer-related, conduct, and hyperactivity/inattention problems subscales of the SDQ; and teacher-reported TDS. Permanent family income was the primary exposure variable; frequency of poverty up to age 11 years was the secondary exposure variable. Maternal psychological distress was operationalised to reflect the trajectory from child birth to age 11. Multivariable logistic regression models were used to estimate the effect of permanent family income on child behaviour at age 11, controlling for maternal psychological distress and other relevant covariates. Results showed a statistically significant protective effect of increased permanent family income on the likelihood of behavioural problems at age 11. This finding was consistent for all SDQ subscales apart from emotional problems, and was strongest for teacher-reported behavioural problems. Maternal distress was an important mediator in the income-child behaviour relationship for parent-reported, but not teacher-reported, behavioural problems. The results of this study strengthen empirical evidence that the child behaviour-income gradient is maintained in older childhood. Mother's psychological distress, particularly longstanding or recurrent, appears to contribute to this relationship. These findings may validate calls for psychosocial and financial supports for families affected by parental mental health issues.

Do clinically anxious children cluster according to their expression of factors that maintain child anxiety?

BACKGROUND

Cognitive Behaviour Therapy (CBT) is an effective treatment for childhood anxiety disorders, yet a significant proportion of children do not benefit from it. CBT for child anxiety disorders typically includes a range of strategies that may not all be applicable for all affected children. This study explored whether there are distinct subgroups of children with anxiety disorders who are characterized by their responses to measures of the key mechanisms that are targeted in CBT (i.e. interpretation bias, perceived control, avoidance, physiological arousal, and social communication).

METHODS

379 clinically anxious children (7-12 years) provided indices of threat interpretation, perceived control, expected negative emotions and avoidance and measures of heart rate recovery following a speech task. Parents also reported on their children's social communication difficulties using the Social Communication Questionnaire (SCQ).

RESULTS

Latent profile analysis identified three groups, reflecting (i) 'Typically anxious' (the majority of the sample and more likely to have Generalized anxiety disorder); (ii) 'social difficulties' (characterized by high SCQ and more likely to have social anxiety disorder and be male); (iii) 'Avoidant' (characterized by low threat interpretation but high avoidance and low perceived control).

LIMITATIONS

Some measures may have been influenced by confounding variables (e.g. physical variability in heart rate recovery). Sample characteristics of the group may limit the generalizability of the results.

CONCLUSIONS

Clinically anxious children appear to fall in to subgroups that might benefit from more targeted treatments that focus on specific maintenance factors. Treatment studies are now required to establish whether this approach would lead to more effective and efficient treatments.

Review: Prevention of anxiety among at-risk children and adolescents - a systematic review and meta-analysis

BACKGROUND

Anxiety disorders are common, often start in childhood and run a chronic course. As such there is a need for effective prevention.

METHODS

We conducted a systematic review and meta-analyses of randomized, controlled trials to prevent the onset of anxiety disorders in 'at risk' young people. Diagnostic and symptom outcomes were examined. Putative moderators were tested as was publication bias.

RESULTS

We included 16 trials (2545 young people). Two trials reported diagnostic outcomes, and significant effects were found for these at end-of-programme (RR = .09, 95%CI = .02 to .16), 6- (RR = .17, 95%CI = .06 to .27) and 12-month (RR = .31, 95%CI .17 to .45) follow-ups. Based on 16 trials, improved anxiety symptoms were significant compared to nonattention controls only, with small effect sizes reported by young people at the end-of-programmes, 6- and 12-month follow-ups; and by parents at the end of the programmes and 12-, but not 6-, month follow-ups. There was no evidence of significant moderation or publication bias.

CONCLUSIONS

Fourteen studies included children and young people who presented with elevated anxiety symptoms, but anxiety disorder was not ruled out in the participants in these studies. Hence, these studies might be reporting results of mixed prevention/early intervention programmes. Prevention programmes that target developmental risk factors, not only disorder maintaining factors, appear most promising. The clinically meaningful impact of anxiety disorder prevention programmes remains unknown.

Using symptom and interference questionnaires to identify recovery among children with anxiety disorders

Questionnaires are widely used in routine clinical practice to assess treatment outcomes for children with anxiety disorders. This study was conducted to determine whether 2 widely used child and parent report questionnaires of child anxiety symptoms and interference (Spence Child Anxiety Scale [SCAS-C/P] and Child Anxiety Impact Scale [CAIS-C/P]) accurately identify recovery from common child anxiety disorder diagnoses as measured by a 'gold-standard' diagnostic interview. Three hundred thirty-seven children (7-12 years, 51% female) and their parents completed the ADIS-IV-C/P diagnostic interview and questionnaire measures (SCAS-C/P and CAIS-C/P) before (Time 1) and after (Time 2) treatment or wait-list. Time 2 parent reported interference (CAIS-P) was found to be a good predictor of absence of any diagnoses (area under the curve [AUC] = .81). In terms of specific diagnoses, Time 2 SCAS-C/P separation anxiety subscale (SCAS-C/P-SA) identified recovery from separation anxiety disorder well (SCAS-C-SA, AUC = .80; SCAS-P-SA, AUC = .82) as did the CAIS-P (AUC = .79). The CAIS-P also successfully identified recovery from social phobia (AUC = .78) and generalized anxiety disorder (AUC = .76). These AUC values were supported by moderate to good sensitivity (.70-.78) and specificity (.70-.73) at the best identified cut-off scores. None of the measures successfully identified recovery from specific phobia. The results suggest that questionnaire measures, particularly the CAIS-P, can be used to identify whether children have recovered from common anxiety disorders, with the exception of specific phobias. Cut-off scores have been identified that can guide the use of routine outcome measures in clinical practice. (PsycINFO Database Record

Recent developments in the treatment of anxiety disorders in children and adolescents

Anxiety disorders are among the most common emotional difficulties experienced by children and young people. They cause significant disturbance to the lives of young people and their families and present a risk for lifelong psychological disturbance. Effective psychological (ie, cognitive-behaviour therapy (CBT)) and pharmacological interventions (eg, selective serotonin reuptake inhibitors (SSRIs)) have been established. However, the risk of adverse effects and unknown long-term effects of using SSRIs has led to recommendations that CBT is delivered as a first-line intervention. Recent innovations have included the development of low-intensity CBT programmes, delivered briefly via parents or online. These hold promise to increase access to psychological therapies for children and young people with these common and severe difficulties.

Parents' difficulties as co-therapists in CBT among non-responding youths with anxiety disorders: Parent and therapist experiences

No increased effect has been associated with parent involvement in cognitive behavioral therapy (CBT) for youths with anxiety disorders. The purpose of this study was to explore parent and therapist experiences of CBT among non-responding youths with anxiety disorders, with a primary focus on parent involvement in therapy. Interpretative phenomenological analysis was applied to 24 sets of semi-structured interviews with families and therapists of anxiety-disordered youths who had not profited from CBT with parental inclusion. From the superordinate theme parents' difficulties acting as co-therapists, which emerged from the analyses, two master themes represented the perspectives of parents (difficulty working together with the youth and feeling unqualified, with limited resources), and two represented the perspectives of therapists (family dynamics stood in the way of progress and difficulty transferring control to parents). Parent and therapist experiences complemented each other, offering two different perspectives on parent difficulties as co-therapists. However, the two groups' views on their respective roles in therapy were in conflict. Parents wished to remain being "just the parents" and for the experts to take over, while therapists wished to act as facilitators transferring the control to parents. Clinical implications are drawn for parental involvement and enhancement of treatment outcomes for likely non-responders.
