Why do children and adolescents (not) seek and access professional help for their mental health problems? A systematic review of quantitative and qualitative studies

Mental health disorders in children and adolescents are highly prevalent yet undertreated. A detailed understanding of the reasons for not seeking or accessing help as perceived by young people is crucial to address this gap. We conducted a systematic review (PROSPERO 42018088591) of quantitative and qualitative studies reporting barriers and facilitators to children and adolescents seeking and accessing professional help for mental health problems. We identified 53 eligible studies; 22 provided quantitative data, 30 provided qualitative data, and one provided both. Four main barrier/facilitator themes were identified. Almost all studies (96%) reported barriers related to young people's individual factors, such as limited mental health knowledge and broader perceptions of help-seeking. The second most commonly (92%) reported theme related to social factors, for example, perceived social stigma and embarrassment. The third theme captured young people's perceptions of the therapeutic relationship with professionals (68%) including perceived confidentiality and the ability to trust an unknown person. The fourth theme related to systemic and structural barriers and facilitators (58%), such as financial costs associated with mental health services, logistical barriers, and the availability of professional help. The findings highlight the complex array of internal and external factors that determine whether young people seek and access help for mental health difficulties. In addition to making effective support more available, targeted evidence-based interventions are required to reduce perceived public stigma and improve young people's knowledge of mental health problems and available support, including what to expect from professionals and services.

Advances in secondary spinal cord injury: role of apoptosis

The outcome of spinal cord injury depends on the extent of secondary damage produced by a series of cellular and molecular events initiated by the primary trauma. This article reviews the evidence that secondary spinal cord injury involves the apoptotic as well as necrotic death of neurons and glial cells. Also discussed are the major factors that can contribute to cell death, such as glutamatergic excitotoxicity, free radical damage, cytokines, and inflammation. The development of innovative therapeutic strategies to reduce secondary spinal cord injury depends on an increased understanding of secondary injury mechanisms at the molecular and biochemical level. Such therapeutic interventions may include the use of antiapoptotic drugs, free radical scavengers, and anti-inflammatory agents. These could be targeted to block key reactions on cellular and molecular injury cascades, thus reducing secondary tissue damage, minimizing side effects, and improving functional recovery.

Use of digital radiography to demonstrate the potential of naproxen as an adjunct in the treatment of rapidly progressive periodontitis

The effect of the non-steroidal anti-inflammatory drug, naproxen, in reducing periodontal disease activity was assessed in 15 patients with rapidly progressive periodontitis. All patients in this double-blind study were treated with scaling and root planing. Thereafter, 7 patients receiving 500 mg naproxen b.i.d. for 3 months, and 8 patients received placebo. Disease activity was assessed in three ways. First, alveolar bone height was determined using standardized radiography. Second, alterations in alveolar bone metabolism were assessed using 99m-Tc-methylene diphosphonate uptake prior to dosing and 3 months later. Finally, bone loss or gain was detected using digital subtraction radiography. In this study, conventional subtraction images were processed to isolate the area of change and superimpose the change on the original radiograph. This allowed determination of both the direction and location of osseous changes. There was significantly less bone loss as determined by analysis of bone height during the 3-month study in the naproxen-treated patients when compared to the placebo-treated patients (p less than 0.001). Radiopharmaceutical uptake was significantly reduced in the alveolar bone in patients receiving naproxen (p less than 0.03), whereas no significant change was observed in the placebo-treated patients. Furthermore, the subtraction radiographs showed a significant increase in the proportion of teeth demonstrating bone gain in the naproxen-treated group. These findings indicate that naproxen may be a useful adjunct to scaling and root planing in patients with rapidly progressive periodontitis.

Clinical Predictors of Response to Cognitive-Behavioral Therapy in Pediatric Anxiety Disorders: The Genes for Treatment (GxT) Study

OBJECTIVE

The Genes for Treatment study is an international, multisite collaboration exploring the role of genetic, demographic, and clinical predictors in response to cognitive-behavioral therapy (CBT) in pediatric anxiety disorders. The current article, the first from the study, examined demographic and clinical predictors of response to CBT. We hypothesized that the child's gender, type of anxiety disorder, initial severity and comorbidity, and parents' psychopathology would significantly predict outcome.

METHOD

A sample of 1,519 children 5 to 18 years of age with a primary anxiety diagnosis received CBT across 11 sites. Outcome was defined as response (change in diagnostic severity) and remission (absence of the primary diagnosis) at each time point (posttreatment, 3-, 6-, and/or 12-month follow-up) and analyzed using linear and logistic mixed models. Separate analyses were conducted using data from posttreatment and follow-up assessments to explore the relative importance of predictors at these time points.

RESULTS

Individuals with social anxiety disorder (SoAD) had significantly poorer outcomes (poorer response and lower rates of remission) than those with generalized anxiety disorder (GAD). Although individuals with specific phobia (SP) also had poorer outcomes than those with GAD at posttreatment, these differences were not maintained at follow-up. Both comorbid mood and externalizing disorders significantly predicted poorer outcomes at posttreatment and follow-up, whereas self-reported parental psychopathology had little effect on posttreatment outcomes but significantly predicted response (although not remission) at follow-up.

CONCLUSION

SoAD, nonanxiety comorbidity, and parental psychopathology were associated with poorer outcomes after CBT. The results highlight the need for enhanced treatments for children at risk for poorer outcomes.

How did the mental health symptoms of children and adolescents change over early lockdown during the COVID-19 pandemic in the UK?

Background

The COVID-19 pandemic has caused extensive disruption to the lives of children and young people. Understanding the psychological effects on children and young people, in the context of known risk factors is crucial to mitigate the effects of the pandemic. This study set out to explore how mental health symptoms in children and adolescents changed over a month of full lockdown in the United Kingdom in response to the pandemic.

Methods

UK-based parents and carers (n = 2673) of school-aged children and young people aged between 4 and 16 years completed an online survey about their child's mental health at two time points between March and May 2020, during early lockdown. The survey examined changes in emotional symptoms, conduct problems and hyperactivity/inattention.

Results

The findings highlighted particular deteriorations in mental health symptoms among preadolescent children, which translated to a 10% increase in those meeting possible/probable caseness criteria for emotional symptoms, a 20% increase in hyperactivity/inattention, and a 35% increase in conduct problems. In contrast, changes among adolescents were smaller (4% and 8% increase for hyperactivity/inattention and conduct problems, respectively) with a small reduction in emotional symptoms (reflecting a 3% reduction in caseness). Overall, there were few differences in change in symptoms or caseness over time according to demographic characteristics, but children and young people in low income households and those with special educational needs and/or neurodevelopmental disorders exhibited elevated symptoms (and caseness) at both time points.

Conclusions

The findings highlight important areas of concern in terms of the potential impact of the first national lockdown on children and young people's adjustment. Developing an understanding of who has been most severely affected by the pandemic, and in what ways, is crucial in order to target effective support where it is most needed.

Assessment and management of anxiety disorders in children and adolescents

Anxiety disorders in childhood and adolescence are extremely common and are often associated with lifelong psychiatric disturbance. Consistent with DSM-5 and the extant literature, this review concerns the assessment and treatment of specific phobias, separation anxiety disorder, generalised anxiety disorder, social anxiety disorder, panic disorder and agoraphobia. Evidence-based psychological treatments (cognitive behaviour therapy; CBT) for these disorders have been developed and investigated, and in recent years promising low-intensity versions of CBT interventions have been proposed that offer a means to increase access to evidence-based treatments. There is some evidence of effectiveness of pharmacological treatments for anxiety disorders in children and young people, however, routine prescription is not recommended due to concerns about potential harm.

Practitioner Review: Anxiety disorders in children and young people - assessment and treatment

Despite significant advancements in our knowledge of anxiety disorders in children and adolescents, they continue to be underrecognised and undertreated. It is critical that these disorders are taken seriously in children and young people as they are highly prevalent, have a negative impact on educational, social and health functioning, create a risk of ongoing anxiety and other mental health disorders across the life span and are associated with substantial economic burden. Yet very few children with anxiety disorders access evidence-based treatments, and there is an urgent need for widespread implementation of effective interventions. This review aimed to provide an overview of recent research developments that will be relevant to clinicians and policymakers, particularly focusing on the development and maintenance of child anxiety disorders and considerations for assessment and treatment. Given the critical need to increase access to effective support, we hope this review will contribute to driving forward a step change in treatment delivery for children and young people with anxiety disorders and their families.

HPA AXIS RELATED GENES AND RESPONSE TO PSYCHOLOGICAL THERAPIES: GENETICS AND EPIGENETICS

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.

Children and adolescents referred for treatment of anxiety disorders: differences in clinical characteristics

BACKGROUND

Reports of the clinical characteristics of children and adolescents with anxiety disorders are typically based on community populations or from clinical samples with exclusion criterion applied. Little is known about the clinical characteristics of children and adolescents routinely referred for treatment for anxiety disorders. Furthermore, children and adolescents are typically treated as one homogeneous group although they may differ in ways that are clinically meaningful.

METHODS

A consecutive series of children (n=100, aged 6-12 years) and adolescents (n=100, aged 13-18 years), referred to a routine clinical service, were assessed for anxiety and comorbid disorders, school refusal and parental symptoms of psychopathology.

RESULTS

Children with a primary anxiety disorder were significantly more likely to be diagnosed with separation anxiety disorder than adolescents. Adolescents with a primary anxiety disorder had significantly higher self and clinician rated anxiety symptoms and had more frequent primary diagnoses of social anxiety disorder, diagnoses and symptoms of mood disorders, and irregular school attendance.

LIMITATIONS

Childhood and adolescence were considered categorically as distinct, developmental periods; in reality changes would be unlikely to occur in such a discrete manner.

CONCLUSIONS

The finding that children and adolescents with anxiety disorders have distinct clinical characteristics has clear implications for treatment. Simply adapting treatments designed for children to make the materials more 'adolescent-friendly' is unlikely to sufficiently meet the needs of adolescents.

Cognitive behaviour therapy for low self-esteem: a preliminary randomized controlled trial in a primary care setting

BACKGROUND AND OBJECTIVES

Low self-esteem (LSE) is associated with psychiatric disorder, and is distressing and debilitating in its own right. Hence, it is frequent target for treatment in cognitive behavioural interventions, yet it has rarely been the primary focus for intervention. This paper reports on a preliminary randomized controlled trial of cognitive behaviour therapy (CBT) for LSE using Fennell's (1997) cognitive conceptualisation and transdiagnostic treatment approach (1997, 1999).

METHODS

Twenty-two participants were randomly allocated to either immediate treatment (IT) (n=11) or to a waitlist condition (WL) (n=11). Treatment consisted of 10 sessions of individual CBT accompanied by workbooks. Participants allocated to the WL condition received the CBT intervention once the waitlist period was completed and all participants were followed up 11 weeks after completing CBT.

RESULTS

The IT group showed significantly better functioning than the WL group on measures of LSE, overall functioning and depression and had fewer psychiatric diagnoses at the end of treatment. The WL group showed the same pattern of response to CBT as the group who had received CBT immediately. All treatment gains were maintained at follow-up assessment.

LIMITATIONS

The sample size is small and consists mainly of women with a high level of educational attainment and the follow-up period was relatively short.

CONCLUSIONS

These preliminary findings suggest that a focused, brief CBT intervention can be effective in treating LSE and associated symptoms and diagnoses in a clinically representative group of individuals with a range of different and co-morbid disorders.

Randomized controlled trial of full and brief cognitive-behaviour therapy and wait-list for paediatric obsessive-compulsive disorder

BACKGROUND

Reviews and practice guidelines for paediatric obsessive-compulsive disorder (OCD) recommend cognitive-behaviour therapy (CBT) as the psychological treatment of choice, but note that it has not been sufficiently evaluated for children and adolescents and that more randomized controlled trials are needed. The aim of this trial was to evaluate effectiveness and optimal delivery of CBT, emphasizing cognitive interventions.

METHODS

A total of 96 children and adolescents with OCD were randomly allocated to the three conditions each of approximately 12 weeks duration: full CBT (average therapist contact: 12 sessions) and brief CBT (average contact: 5 sessions, with use of therapist-guided workbooks), and wait-list/delayed treatment. The primary outcome measure was the child version of the semi-structured interviewer-based Yale-Brown Obsessive Compulsive Scale.

CLINICAL TRIAL REGISTRATION

http://www.controlled-trials.com/ISRCTN/; unique identifier: ISRCTN29092580.

RESULTS

There was statistically significant symptomatic improvement in both treatment groups compared with the wait-list group, with no significant differences in outcomes between the two treatment groups. Controlled treatment effect sizes in intention-to-treat analyses were 2.2 for full CBT and 1.6 for brief CBT. Improvements were maintained at follow-up an average of 14 weeks later.

CONCLUSIONS

The findings demonstrate the benefits of CBT emphasizing cognitive interventions for children and adolescents with OCD and suggest that relatively lower therapist intensity delivery with use of therapist-guided workbooks is an efficient mode of delivery.

Examining changes in parent-reported child and adolescent mental health throughout the UK's first COVID-19 national lockdown

BACKGROUND

The COVID-19 pandemic has significantly changed the lives of children and adolescents, forcing them into periods of prolonged social isolation and time away from school. Understanding the psychological consequences of the UK's lockdown for children and adolescents, the associated risk factors, and how trajectories may vary for children and adolescents in different circumstances is essential so that the most vulnerable children and adolescents can be identified, and appropriate support can be implemented.

METHODS

Participants were a convenience sample of parents and carers (n = 2,988) in the UK with children and adolescents aged between 4 and 16 years who completed an online survey about their child's mental health. Growth curve analysis was used to examine the changes in conduct problems, hyperactivity/inattention, and emotional symptoms between the end of March/beginning of April and July using data from monthly assessments over four months. Additionally, growth mixture modelling identified mental health trajectories for conduct problems, hyperactivity/inattention, and emotional symptoms separately, and subsequent regression models were used to estimate predictors of mental health trajectory membership.

RESULTS

Overall levels of hyperactivity and conduct problems increased over time, whereas emotional symptoms remained relatively stable, though declined somewhat between June and July. Change over time varied according to child age, the presence of siblings, and with Special Educational Needs (SEN)/Neurodevelopmental Disorders (ND). Subsequent growth mixture modelling identified three, four, and five trajectories for hyperactivity/inattention, conduct problems, and emotional symptoms, respectively. Though many children maintained 'stable low' symptoms, others experienced elevated symptoms by July. These children were more likely to have a parent/carer with higher levels of psychological distress, to have SEN/ND, or to be younger in age.

CONCLUSIONS

The findings support previous literature and highlight that certain risk factors were associated with poorer mental health trajectories for children and adolescents during the pandemic.

A vertebral dislocation model of spinal cord injury in rats

A new model of spinal cord injury (SCI) has been developed in the rat, which produces axonal and vascular injury within the spinal cord through lateral displacement of the vertebral column. An electromechanical feedback-controlled device produces the injury by displacing the vertebral column to the left hand side. The speed and lateral displacement is controllable by the user, and the resulting injury ranges from no histologically evident injury, to total disruption of the vertebral column with associated widespread axonal and vascular damage. Histological and immunohistological techniques were employed to correlate mechanical parameters with the extent of pathological injury of spinal cord. Axonal injury was most severe in the left lateral white matter, and vascular injury was concentrated in the gray matter.

Comparisons of the Factor Structure and Measurement Invariance of the Spence Children's Anxiety Scale-Parent Version in Children with Autism Spectrum Disorder and Typically Developing Anxious Children

The Spence Children's Anxiety Scale-Parent version (SCAS-P) is often used to assess anxiety in children with autism spectrum disorder (ASD), however, little is known about the validity of the tool in this population. The aim of this study was to determine whether the SCAS-P has the same factorial validity in a sample of young people with ASD (n = 285), compared to a sample of typically developing young people with anxiety disorders (n = 224). Poor model fit with all of the six hypothesised models precluded invariance testing. Exploratory factor analysis indicated that different anxiety phenomenology characterises the two samples. The findings suggest that cross-group comparisons between ASD and anxious samples based on the SCAS-P scores may not always be appropriate.

Advances in spinal cord regeneration

Spinal cord injury continues to be a major cause of morbidity, particularly among young people involved in vehicle-related trauma, falls, and sports injuries. Although research advances are still a long way from clinical treatments, recent studies on animals have indicated new possibilities for recovery of function. In this review, these new findings on the use of neurotrophic factors, antibodies to inhibitory molecules, electrical stimulation, and transplantation of peripheral nerves and olfactory glial cells, and their success in achieving functional recovery after adult spinal cord lesions are discussed.

Genome-wide association study of response to cognitive-behavioural therapy in children with anxiety disorders

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.

Adolescents' perceived barriers and facilitators to seeking and accessing professional help for anxiety and depressive disorders: a qualitative interview study

Anxiety and depressive disorders are the most common mental health disorders in adolescents, yet only a minority of young people with these disorders access professional help. This study aims to address this treatment gap by improving our understanding of barriers and facilitators to seeking/accessing professional help as perceived by adolescents with anxiety/depressive disorders identified in the community. Twenty-two adolescents, aged 11-17 years, who met diagnostic criteria for a current anxiety and/or depressive disorder were identified through school-based screening. In-depth qualitative interviews were conducted one-to-one with each adolescent and adolescents' parents were interviewed separately for the purpose of data triangulation. Data were analysed using reflexive thematic analysis. We identified four themes capturing adolescent perceived barriers and facilitators to seeking/accessing professional help for anxiety and depressive disorders: (1) making sense of difficulties, (2) problem disclosure, (3) ambivalence to seeking help, and (4) the instrumental role of others. Barriers/facilitators identified within each theme reflect important developmental characteristics of adolescence, such as a growing need for autonomy and concerns around negative social evaluation. At the same time, the results highlight adolescents' dependency on other people, mainly their parents and school staff, when it comes to successfully accessing professional help for their mental health difficulties. This study identifies a number of barriers/facilitators that influence help-seeking behaviour of adolescents with anxiety and/or depressive disorders. These factors need to be addressed when targeting treatment utilisation rates in this particular group of young people.

Interpretation of ambiguity: Differences between children and adolescents with and without an anxiety disorder

BACKGROUND

Theory and treatment of anxiety disorders in young people are commonly based on the premise that interpretation biases found in anxious adults are also found in children and adolescents. Although there is some evidence that this may be the case, studies have not typically taken age into account, which is surprising given the normative changes in cognition that occur throughout childhood. The aim of the current study was to identify whether associations between anxiety disorder status and interpretation biases differed in children and adolescents.

METHODS

The responses of children (7-10 years) and adolescents (13-16 years) with and without anxiety disorders (n=120) were compared on an ambiguous scenarios task.

RESULTS

Children and adolescents with an anxiety disorder showed significantly higher levels of threat interpretation and avoidant strategies than non-anxious children and adolescents. However, age significantly moderated the effect of anxiety disorder status on interpretation of ambiguity, in that adolescents with anxiety disorders showed significantly higher levels of threat interpretation and associated negative emotion than non-anxious adolescents, but a similar relationship was not observed among children.

CONCLUSIONS

The findings suggest that theoretical accounts of interpretation biases in anxiety disorders in children and adolescents should distinguish between different developmental periods. For both ages, treatment that targets behavioral avoidance appears warranted. However, while adolescents are likely to benefit from treatment that addresses interpretation biases, there may be limited benefit for children under the age of ten.

The Effectiveness of Psychological Therapies for Anxiety Disorders in Adolescents: A Meta-Analysis

Anxiety disorders are common in adolescence but outcomes for adolescents are unclear and we do not know what factors moderate treatment outcome for this age group. We conducted meta-analyses to establish the effectiveness of psychological therapies for adolescent anxiety disorders in (i) reducing anxiety disorder symptoms, and (ii) remission from the primary anxiety disorder, compared with controls, and examine potential moderators of treatment effects. The protocol was registered with PROSPERO (CRD42018091744). Electronic databases (Web of Science, MEDLINE, Psycinfo, EMBASE) were searched from January 1990 to December 2019. 2511 articles were reviewed, those meeting strict criteria were included. Random effects meta-analyses were conducted. Analyses of symptom severity outcomes comprised sixteen studies (CBT k = 15, non-CBT k = 1; n = 766 adolescents), and analyses of diagnostic remission outcomes comprised nine (CBT k = 9; n = 563 adolescents). Post-treatment, those receiving treatment were significantly more likely to experience reduced symptom severity (SMD = 0.454, 95% CI 0.22–0.69) and remission from the primary anxiety disorder than controls (RR = 7.94, 95% CI 3.19–12.7) (36% treatment vs. 9% controls in remission). None of the moderators analysed were statistically significant. Psychological therapies targeting anxiety disorders in adolescents are more effective than controls. However, with only just over a third in remission post-treatment, there is a clear need to develop more effective treatments for adolescents, evaluated through high-quality randomised controlled trials incorporating active controls and follow-up data.

Non-replication of the association between 5HTTLPR and response to psychological therapy for child anxiety disorders

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.

A randomized controlled trial of internet-delivered cognitive behaviour therapy for adolescent anxiety disorders in a routine clinical care setting with and without parent sessions

BACKGROUND

Computerized treatments have been shown to be effective in young people with anxiety disorders within research settings. The aims of this study were to evaluate a self-completed, therapist-supported online treatment for adolescent anxiety disorders in a routine clinical care setting and examine whether additional sessions for parents improved treatment outcome.

METHOD

Sixty adolescents (13-18 years) referred by primary and secondary care services for treatment of an anxiety disorder and their parent(s) were randomly allocated to begin treatment immediately or after a 16-week waitlist. Half the parents (receiving treatment immediately or after a waitlist) were allocated to receive sessions themselves. Assessments were conducted pre- and posttreatment and at 6-month follow-up.

RESULTS

There was no significant difference posttreatment between the immediate treatment and waitlist groups in remission of primary anxiety disorder (Odds Ratio (OR) = 2.19, 95% CI: 0.72-6.70). Parent sessions did not significantly improve adolescent outcomes immediately or at 6-month follow-up (OR = 0.75, 95% CI: 0.26-2.15; OR = 1.14, 95% CI: 0.42-3.15).

CONCLUSIONS

Within a routine clinical care setting, a therapist-supported online treatment failed to deliver significantly better outcomes for adolescents with anxiety disorders than a waitlist. Further research is needed to develop more effective treatments for this population.

Genetic variation in the endocannabinoid system and response to Cognitive Behavior Therapy for child anxiety disorders

Extinction learning is an important mechanism in the successful psychological treatment of anxiety. Individual differences in response and relapse following Cognitive Behavior Therapy may in part be explained by variability in the ease with which fears are extinguished or the vulnerability of these fears to re-emerge. Given the role of the endocannabinoid system in fear extinction, this study investigates whether genetic variation in the endocannabinoid system explains individual differences in response to CBT. Children (N = 1,309) with a primary anxiety disorder diagnosis were recruited. We investigated the relationship between variation in the CNR1, CNR2, and FAAH genes and change in primary anxiety disorder severity between pre- and post-treatment and during the follow-up period in the full sample and a subset with fear-based anxiety disorder diagnoses. Change in symptom severity during active treatment was nominally associated (P < 0.05) with two SNPs. During the follow-up period, five SNPs were nominally associated with a poorer treatment response (rs806365 [CNR1]; rs2501431 [CNR2]; rs2070956 [CNR2]; rs7769940 [CNR1]; rs2209172 [FAAH]) and one with a more favorable response (rs6928813 [CNR1]). Within the fear-based subset, the effect of rs806365 survived multiple testing corrections (P < 0.0016). We found very limited evidence for an association between variants in endocannabinoid system genes and treatment response once multiple testing corrections were applied. Larger, more homogenous cohorts are needed to allow the identification of variants of small but statistically significant effect and to estimate effect sizes for these variants with greater precision in order to determine their potential clinical utility. © 2016 The Authors.

Relationships between local school closures due to the COVID-19 and mental health problems of children, adolescents, and parents in Japan

The widespread impacts of COVID-19 have affected both child and parent mental health worldwide. This study aimed to investigate the relationship between school closures due to COVID-19 and child and parent mental health in Japan. A sample of 1,984 Japanese parents with children and adolescents aged 6-15 years participated. The parents responded to online questionnaires about their own mental health and that of their children cross-sectionally. Participants were divided into three school situations based on the past week: full school closure, partial school closure, and full school open. Results indicated that 2.02% (n = 40) of the participants were in full school closure and 5.95% (n = 118) of the participants were in partial school closure. The results indicated that, after controlling for other variables regarding the pandemic, full school closure was associated with much higher scores in both child and parent mental health problems compared to full school open. Moderately higher scores were found only for anxiety symptoms in both children and parents under partial school closure compared to where schools were fully open. Consideration of the needs of families is necessary in the context of both full and partial school closures to prevent deteriorating mental health.
