Safety behaviours in social anxiety: An examination across adolescence

BACKGROUND

Safety behaviours have been shown to be a key maintaining factor in Social Anxiety Disorder (SAD). In adults, a two-factor structure of safety behaviours reflecting 'avoidance' and 'impression-management' types has been identified. This has not yet been investigated in adolescents.

AIMS

We set out to investigate the factor structure of safety behaviours in relation to adolescent social anxiety symptoms and SAD, the extent to which this varies by age, and then to examine the association between the derived factor scores and other social anxiety related phenomena.

METHOD

Questionnaire measures of social anxiety symptoms, cognitions and safety behaviours, peer relationship outcomes, general anxiety and depression were collected from a community sample of 584 younger (11-14 years) and 208 older (16-18 years) adolescents, and a clinical sample of 80 adolescents (11-18 years) with a primary diagnosis of SAD. Four hypotheses were investigated using exploratory and confirmatory factor analyses, regressions, correlations and path analyses.

RESULTS

A two-factor structure reflecting 'avoidance' and 'impression-management' safety behaviours was supported in the community and clinical sample. Older adolescents were found to use 'impression-management' behaviours more than younger adolescents after controlling for overall safety behaviour score. Both types of safety behaviour were significantly positively associated with social anxiety symptoms and cognitions. Path analyses revealed an indirect effect of social anxiety symptoms on peer victimisation, social satisfaction and friendship quality via 'avoidance', but not 'impression-management' safety behaviours.

CONCLUSIONS

Both 'avoidance' and 'impression-management' safety behaviours are associated with social anxiety symptoms and cognitions in youth, with age-related differences in their frequency. 'Avoidance' behaviours are specifically associated with negative outcomes for quality of peer relationships.

Do oropharyngeal throat packs prevent fluid ingestion during orthognathic surgery?

The oropharyngeal throat pack is commonly used in oral and maxillofacial surgery despite debated evidence regarding its barrier function. The study objectives were to investigate whether the oropharyngeal pack reduces blood ingestion and to evaluate its relationship with postoperative nausea and vomiting (PONV) and throat pain. This was a single-center, parallel group, single-blind randomized controlled trial. Participants undergoing orthognathic surgery, age ≥16 years, were included in the study. After intubation and prior to surgery start, the treatment group received oropharyngeal packing; the control group received no packing. Outcome variables were the quality of gastric contents aspirated by nasogastric tube (bloody or not bloody), PONV, and throat pain (visual analog scale). Thirty patients (treatment n = 15; control n = 15) were randomized and analyzed. There was no difference between the groups in quality of gastric contents (P = 1.00) or incidence of PONV at 2 hours and 24 hours (P = 1.00). Throat pain incidence and severity at 2 hours were both higher in the treatment group, but this was not statistically significant (P = 0.128, P = 0.223). The results indicate that the oropharyngeal pack is not an effective barrier against blood ingestion. Oropharyngeal packs do not improve or worsen PONV, but may increase throat pain.

Annual Research Review: Immersive virtual reality and digital applied gaming interventions for the treatment of mental health problems in children and young people: the need for rigorous treatment development and clinical evaluation

BACKGROUND

Mental health problems in children and young people are common and can lead to poor long-term outcomes. Despite the availability of effective psychological interventions for mental health disorders, only a minority of affected children and young people access treatment. Digital interventions, such as applied games and virtual reality (VR), that target mental health problems in children and young people may hold a key to increasing access to, engagement with, and potentially the effectiveness of psychological treatments. To date, several applied games and VR interventions have been specifically developed for children and young people. This systematic review aims to identify and synthesize current data on the experience and effectiveness of applied games and VR for targeting mental health problems in children and young people (defined as average age of 18 years or below).

METHODS

Electronic systematic searches were conducted in Medline, PsycINFO, CINAHL, and Web of Science.

RESULTS

Nineteen studies were identified that examined nine applied games and two VR applications, and targeted symptoms of anxiety, depression, and phobias using both quantitative and qualitative methodologies. Existing evidence is at a very early stage and studies vary extensively in key methodological characteristics. For applied games, the most robust evidence is for adolescent depressive symptoms (medium clinical effect sizes). Insufficient research attention has been given to the efficacy of VR interventions in children and young people.

CONCLUSIONS

The evidence to date is at a very early stage. Despite the enthusiasm for applied games and VR, existing interventions are limited in number and evidence of efficacy, and there is a clear need for further co-design, development, and evaluation of applied games and VR before they are routinely offered as treatments for children and young people with mental health problems.

Supporting Parents & Kids Through Lockdown Experiences (SPARKLE): A digital parenting support app implemented in an ongoing general population cohort study during the COVID-19 pandemic: A structured summary of a study protocol for a randomised controlled trial

Objectives

The COVID-19 related lockdowns and distancing measures have presented families with unprecedented challenges. A UK-wide cohort study tracking changes in families’ mental health since early lockdown (Co-SPACE) found a significant rise in primary school-aged children’s behaviour problems and associated family-related stress. Three-quarters of parents in Co-SPACE also reported wanting extra support. In SPARKLE, we will examine whether providing Co-SPACE families with a smartphone application delivering information and parenting support, Parent Positive, can reverse the negative effects of the pandemic on children and parents. The efficacy on child and parent outcomes and cost-effectiveness of Parent Positive will be examined. We will also test whether the effects are moderated by pre-existing levels of child conduct problems and usage of Parent Positive. Exploratory analyses will examine whether other baseline characteristics or lockdown circumstances moderate the effects of Parent Positive.

Trial design

SPARKLE is a two-arm superiority parallel group randomised controlled trial embedded in an existing large UK-wide self-selected community cohort – Co-SPACE. Those who consent to SPARKLE will be randomised 1:1 to either Parent Positive or Follow-up As Usual (FAU).

Participants

Co-SPACE (a UK-wide longitudinal cohort study) parents aged ≥18 who have children aged 4-10 years will be eligible for SPARKLE.

Intervention and comparator

Parent Positive: is a digital public health intervention that can be delivered rapidly at scale to support parents in managing their children’s behaviour to reduce conduct problems and levels of family conflict, which were exacerbated during the first lockdown, and which may increase further in future months as families need to cope with continuous uncertainty and further disruption to their daily lives. Co-designed with parents and based on decades of parenting research, Parent Positive consists of three elements: (i) Parenting Boosters: where advice, delivered in the form of narrated animations, videos, graphics and text is provided to help parents with eight common parenting challenges; (ii) Parenting Exchange: a facilitated parent-to-parent communication and peer support platform and; (iii) Parent Resources: giving access to carefully selected high-quality, evidence-based online parenting resources.

Follow-up as Usual: FAU was selected as a comparator because the public health nature meant that an active comparator was not appropriate due to the pragmatic, rapid implementation of the trial. Individuals randomised to FAU will receive no intervention for the first two months while the data for baseline (T1), T2 and T3 are collected. They will then be given full access to the app until 30th November 2021.

Main outcomes

Outcome measures will be collected remotely through Qualtrics according to the Co-SPACE schedule at baseline (T1), which will be the Co-SPACE survey data obtained immediately prior to randomisation, and then at one month (T2) and two months (T3) post-randomisation. Measures will be collected to assess group differences in child and parent outcomes, costs and service utilisation, and adverse events. Usage of Parent Positive will also be tracked. The primary outcome is parent-reported child conduct problems at one-month post-randomisation measured using the Strengths and Difficulties Questionnaire conduct problems subscale.

Randomisation

Enrolled participants will be allocated to Parent Positive or FAU at the ratio of 1:1 by simple randomisation using the Randomizer function within the Qualtrics programme. Neither blocking nor stratification will be used.

Blinding (masking)

It is not possible to blind parents enrolled in the study and Qualtrics will automatically inform parents of their group allocation. Blinded members of the research team and the senior statistician will not be given access to the Qualtrics system or the data in order to remain blinded until after the analysis is complete. We do not anticipate any serious harms associated with taking part in the intervention, therefore there will be no need to unblind any blinded staff during the study. The junior statistician will be unblinded throughout.

Numbers to be randomised (sample size)

A total of 616 will be recruited into the trial with 308 consenting parents randomised to each treatment arm.

Using the 11-item Version of the RCADS to Identify Anxiety and Depressive Disorders in Adolescents

The purpose of this study was to identify items from the Revised Children's Anxiety and Depression Scale - RCADS-C/P that provided a brief, reliable and valid screen for anxiety and/or depressive disorders in adolescents. In addition, we examined whether adding items assessing suicidal ideation (Moods and Feelings Questionnaire - MFQ- C/P) and symptom impact and duration (items adapted from the Strengths and Difficulties Questionnaire - SDQ) improved the identification of adolescents with anxiety and/or depressive disorders. We compared two samples of adolescents and their parents - a community sample, recruited through secondary schools in England (n = 214) and a clinic-referred sample, who met diagnostic criteria for anxiety and/or depressive disorder and were recruited through a university-based research clinic (n = 246). Participants completed the RCADS-C/P with additional symptom impact and duration items, and the MFQ-C/P. Using ROC curve analyses, we identified a set of 11 RCADS-C/P items (6 addressing anxiety and 5 depression symptoms) for adolescent- and parent-report. This set of 11 symptom items achieved sensitivity/specificity values > .75, which were comparable to corresponding values for the RCADS-47-C/P. Combining adolescent and parent-report improved the identification of anxiety/depression in adolescents compared to using adolescent-report alone. Finally, adding two symptom impact items further improved the sensitivity/specificity of the 11 symptom items, whereas adding suicidal ideation items did not. The 11 RCADS items accurately discriminated between the community and clinic-referred sample with anxiety and/or depressive disorders and have the potential to quickly and accurately identify adolescents with these disorders in community settings.

Delivering cognitive therapy for adolescent social anxiety disorder in NHS CAMHS: a qualitative analysis of the experiences of young people, their parents and clinicians-in-training

BACKGROUND

Social anxiety disorder (SAD) is common. It usually starts in adolescence, and without treatment can disrupt key developmental milestones. Existing generic treatments are less effective for young people with SAD than with other anxiety disorders, but an adaptation of an effective adult therapy (CT-SAD-A) has shown promising results for adolescents.

AIMS

The aim of this study was to conduct a qualitative exploration to contribute towards the evaluation of CT-SAD-A for adoption into Child and Adolescent Mental Health Services (CAMHS).

METHOD

We used interpretative phenomenological analysis (IPA) to analyse the transcripts of interviews with a sample of six young people, six parents and seven clinicians who were learning the treatment.

RESULTS

Three cross-cutting themes were identified: (i) endorsing the treatment; (ii) finding therapy to be collaborative and active; challenging but helpful; and (iii) navigating change in a complex setting. Young people and parents found the treatment to be useful and acceptable, although simultaneously challenging. This was echoed by the clinicians, with particular reference to integrating CT-SAD-A within community CAMHS settings.

CONCLUSIONS

The acceptability of the treatment with young people, their parents and clinicians suggests further work is warranted in order to support its development and implementation within CAMHS settings.

Cognitive therapy compared with CBT for social anxiety disorder in adolescents: a feasibility study

BACKGROUND

Social anxiety disorder (SAD) is common, typically starts in adolescence and has a low natural recovery rate. Existing psychological treatments for adolescent SAD are only moderately effective. It is possible that recovery rates for adolescents could be substantially improved by adapting a psychological therapy that is highly effective among adults with SAD.

OBJECTIVES

To train child and adolescent mental health services (CAMHS) therapists to deliver cognitive therapy for SAD in adolescents (CT-SAD-A) and assess therapist competence. To estimate the costs to the NHS of training therapists to deliver CT-SAD-A and the mean cost per adolescent treated. To examine the feasibility of a randomised controlled trial (RCT) to compare CT-SAD-A with the general form of cognitive-behavioural therapy that is more commonly used.

DESIGN

During the training phase of the study, it became clear that the RCT would not be feasible because of high staff turnover and unfilled posts within CAMHS and changes in the nature of referrals, which meant that few young people with primary SAD were accessing some of the participating services. The study design was altered to comprise the following: a training case series of CT-SAD-A delivered in routine CAMHS, an estimate of the cost to the NHS of training therapists to deliver CT-SAD-A and of the mean cost per adolescent treated, and qualitative interviews with participating young people, parents, therapists and service managers/leads.

SETTING

Five CAMHS teams within Berkshire Healthcare and Oxford Health NHS Foundation Trusts.

PARTICIPANTS

Eight therapists received training in CT-SAD-A. Twelve young people received CT-SAD-A, delivered by six therapists. Six young people, six parents, seven therapists and three managers participated in qualitative interviews.

INTERVENTIONS

Cognitive therapy for social anxiety disorder in adolescents (CT-SAD-A).

MAIN OUTCOME MEASURES

Measured outcomes included social anxiety symptoms and diagnostic status, comorbid symptoms of anxiety and depression, social and general functioning, concentration in class and treatment acceptability. Patient level utilisation of the intervention was collected using clinicians' logs.

RESULTS

Nine out of 12 participants achieved good outcomes across measures (r ≥ 0.60 across social anxiety measures). The estimated cost of delivering CT-SAD-A was £1861 (standard deviation £358) per person. Qualitative interviews indicated that the treatment was acceptable to young people, parents and therapists, but therapists and managers experienced challenges when implementing the training and treatment within the current CAMHS context.

LIMITATIONS

Findings were based on a small, homogeneous sample and there was no comparison arm.

CONCLUSIONS

CT-SAD-A is a promising treatment for young people with SAD, but the current CAMHS context presents challenges for its implementation.

FUTURE WORK

Further work is needed to ensure that CAMHS can incorporate and test CT-SAD-A. Alternatively, CT-SAD-A should be delivered and tested in other settings that are better configured to treat young people whose lives are held back by SAD. The new schools Mental Health Support Teams envisaged in the 2017 Children's Mental Health Green Paper may provide such an opportunity.

Delivering cognitive therapy for adolescent social anxiety disorder in NHS CAMHS: a clinical and cost analysis

BACKGROUND

Cognitive therapy, based on the Clark and Wells (1995) model, is a first-line treatment for adults with social anxiety disorder (SAD), and findings from research settings suggest it has promise for use with adolescents (Cognitive Therapy for Social Anxiety Disorder in Adolescents; CT-SAD-A). However, for the treatment to be suitable for delivery in routine clinical care, two questions need to be addressed.

AIMS

Can therapists be trained to achieve good outcomes in routine Child and Adolescent Mental Health Services (CAMHS), and what are the costs associated with training and treatment?

METHOD

CAMHS therapists working in two NHS trusts received training in CT-SAD-A. They delivered the treatment to adolescents with SAD during a period of supervised practice. We examined the clinical outcomes for the 12 patients treated during this period, and estimated costs associated with treatment and training.

RESULTS

Treatment produced significant improvements in social anxiety symptoms, general anxiety and depression symptoms, and reductions in putative process measures. Seventy-five per cent (9 out of 12) patients showed a reliable and clinically significant improvement in social anxiety symptoms, and 64% (7/11) lost their primary diagnosis of SAD. The total cost to the NHS of the CT-SAD-A treatment was £4047 (SD = £1003) per adolescent treated, of which £1861 (SD = £358) referred to the specific estimated cost of face-to-face delivery; the remaining cost was for training and supervising therapists who were not previously familiar with the treatment.

CONCLUSIONS

This study provides preliminary evidence that clinicians can deliver good patient outcomes for adolescents with SAD in routine CAMHS during a period of supervised practice after receiving a 2-day training workshop. Furthermore, the cost of delivering CT-SAD-A with adolescents appeared to be no more than the cost of delivering CT-SAD with adults.

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.

The identification and psychological treatment of panic disorder in adolescents: a survey of CAMHS clinicians

BACKGROUND

Panic disorder is experienced by around 1% of adolescents and has a significant impact on social and academic functioning. Preliminary evidence supports the effectiveness of panic disorder-specific treatment in adolescents with panic disorder; however, panic disorder may be overlooked in adolescents due to overlapping symptoms with other anxiety disorders and other difficulties being more noticeable to others. The aim of this study was to establish what training National Health Service (NHS) Child and Adolescent Mental Health Services (CAMHS) clinicians have received in psychological therapies and panic disorder and how they identify and treat panic disorder in adolescents.

METHOD

CAMHS clinicians from a range of professions (n = 427), who were delivering psychological treatments to children and adolescents with anxiety disorders, participated. They completed a cross-sectional, online survey, including a vignette describing an adolescent with panic disorder, and were asked to identify the main diagnosis or presenting problem.

RESULTS

Less than half the clinicians (48.6%) identified panic disorder or panic symptoms as the main presenting problem from the vignette. The majority of clinicians suggested CBT would be their treatment approach. However, few identified an evidence-based treatment protocol for working with young people with panic disorder. Almost half the sample had received no training in cognitive behaviour therapy (CBT), and around a fifth had received no training in delivering psychological treatments.

CONCLUSIONS

Only half of CAMHS clinicians identified panic disorder from a vignette and although CBT treatments are widely offered, only a minority of adolescents with panic disorder are receiving treatments developed for and evaluated with young people with panic disorder. There is a vital need for clinician training, the use of tools that aid identification and the implementation of evidence-based treatments within CAMHS.

KEY PRACTITIONER MESSAGE

Panic disorder affects around 1% of adolescents, adversely impacting social, academic and long-term life functioning. There is preliminary evidence for the effectiveness of a panic disorder-specific treatment of panic disorder in adolescents. Clinicians struggle to identify panic disorder or suitable treatment protocols for treating adolescents, although most would use CBT as the treatment approach. There is a vital need for clinician training, tools that aid identification of young people with panic disorder and evidence-based treatments that can be delivered in routine clinical settings.

A Systematic Review of Parental Involvement in Cognitive Behavioural Therapy for Adolescent Anxiety Disorders

Anxiety disorders are common among adolescents and lead to poor long-term outcomes. Cognitive Behavioural Therapy (CBT) is an evidenced-based intervention for adolescent anxiety disorders, but little is known about whether and how parents should be involved. This systematic review evaluated how parents have been involved and associated treatment outcomes in studies of CBT for adolescent anxiety disorders. Electronic systematic searches were conducted in PsycINFO, Embase, CINAHL, Medline, AMED databases, to identify studies investigating CBT for adolescent anxiety disorder(s) that included parents in treatment. Twenty-three papers were identified. Parents were involved in treatment in a number of different ways: by attending separate parent sessions, joint parent–adolescent sessions, or both, or through provision of a workbook while attending some adolescent sessions. Content varied but was most typically aimed at the parent developing an understanding of core CBT components and skills to help them manage their adolescent’s anxiety and avoidance. Treatment outcomes indicate that CBT with parental involvement is an effective intervention for adolescent anxiety disorders; however, it is not possible to draw conclusions regarding whether parental involvement (generally or in any particular form) enhances treatment outcomes. Poor reporting and methodological issues also limit the conclusions. Further research is required to identify whether there are particular types of parental involvement in CBT that bring clinical benefits to adolescents with anxiety disorders generally, as well as in particular circumstances.

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.

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.

Secondary school practitioners' beliefs about risk factors for school attendance problems: a qualitative study

School staff have an important role to play in identifying and assisting pupils who require additional support to regularly attend school, but their beliefs about risk factors might influence their decisions regarding intervention. This qualitative study investigated educational practitioners' beliefs about risk factors for attendance problems. Sixteen practitioners from three secondary schools were interviewed via focus groups. Data were analysed using thematic analysis. Practitioners identified risk factors related to the individual, their family, peers and school. Poor mental health was identified as a risk factor, but practitioners primarily focused on anxiety rather than other mental health problems like depression or behavioural disorders. The overall perception was that school factors were less important than individual, family and peer factors. Implications include a need for increased awareness of the role of school factors in attendance problems, focus on promoting positive peer and pupil-teacher relationships, and collaborative working between young people, families and schools.

Protocol for a randomised controlled feasibility study examining the efficacy of brief cognitive therapy for the Treatment of Anxiety Disorders in Adolescents (TAD-A)

Background

Anxiety disorders affect a quarter of the population during their lifetime, and typically emerge in childhood or adolescence. Anxiety disorders disrupt young people’s social, emotional and academic development and in the absence of treatment, often follow a chronic course. Although effective treatments, such as Cognitive Behaviour Therapy (CBT), exist, only a small proportion of adolescents with anxiety disorders who need treatment receive them. Barriers to treatment provision include the fact that CBT typically requires 14–16 sessions by a highly qualified therapist and services are stretched – resulting in lengthy waiting lists and limited access to treatment. This highlights the importance of developing new ways of providing effective treatments for adolescent anxiety disorders. This study aims to assess the feasibility of a future, large-scale trial. This will give a clear indication of the likely success of running a randomised controlled trial to compare a new, brief cognitive therapy treatment to an existing CBT group therapy for adolescents with anxiety disorders.

Methods/design

The study will examine whether a definitive trial can be conducted on the basis of a feasibility RCT using a number of well-defined criteria. The feasibility RCT is a single-centre, randomised control trial. Forty-eight Young people (age 11–17.5 years) attending a university research clinic, who meet the diagnostic criteria for a DSM-5 anxiety disorder, will be randomly allocated to receive either (1) Adolescent Cognitive Therapy for Anxiety (ACTA), which involves six 60–90-min sessions and a booster session or (2) group CBT, which involves eight 2-h sessions and a booster session. As part of the feasibility indicators, patient outcomes, expectations and experiences, as well as health economic factors, will be assessed before, at the end of treatment and at a 3-month follow-up.

Discussion

The successful delivery of a future, definitive trial has the potential to bring direct benefits to young people and their families, adolescent mental health service providers, as well as benefits to adult mental health services and society more broadly by disrupting the negative trajectory commonly associated with adolescent anxiety disorders.

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.

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.

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.

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.

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.

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.
