Predicting remission following CBT for childhood anxiety disorders: a machine learning approach.

Background: The identification of predictors of treatment response is crucial for improving treatment outcome for children with anxiety disorders. Machine learning methods provide opportunities to identify combinations of factors that contribute to risk prediction models.

Methods: A machine learning approach was applied to predict anxiety disorder remission in a large sample of 2114 anxious youth (5-18 years).

Validation of the Parent-report Pandemic Anxiety Scale (PAS-P) in the context of COVID-19.

Unlabelled: To be able to develop effective policy and targeted support for children and young people, it is vital to develop and validate measures that enable us to understand what aspects of pandemics are associated with anxiety and stress across a wide age range. We examined the psychometric properties of the Pandemic Anxiety Scale- Parent-report (PAS-P), which measures levels of child and adolescent pandemic-related anxieties. Factor structure, reliability, and convergent and discriminant validity of the PAS-P was assessed in a convenience sample of parents/carers (= 8410) over at three time points in 2020 when COVID-19 case rates and restrictions varied.

Cognitive and behavioural processes in adolescents with social anxiety disorder.

Background: A better understanding of the processes that maintain social anxiety disorder (SAD) in adolescents could improve treatment outcomes. This study aimed to establish whether cognitive and behavioural processes known to be important in the maintenance of adult SAD are observed in adolescent populations and whether they are specific to SAD.

Methods: We recruited three groups of adolescents (12-18y): (1) 90 adolescents with a SAD diagnosis, (2) 58 adolescents with an anxiety disorder that was not SAD, and (3) 45 community-based adolescents.

Moderators of the Effects of a Digital Parenting Intervention on Child Conduct and Emotional Problems Implemented During the COVID-19 Pandemic: Results From a Secondary Analysis of Data From the Supporting Parents and Kids Through Lockdown Experiences (SPARKLE) Randomized Controlled Trial.

Background: A smartphone app, Parent Positive, was developed to help parents manage their children's conduct and emotional problems during the COVID-19 pandemic. A randomized controlled trial, Supporting Parents and Kids Through Lockdown Experiences (SPARKLE), found Parent Positive to be effective in reducing children's emotional problems. However, app effectiveness may be influenced by a range of child, family, socioeconomic, and pandemic-related factors.

Psychometric Properties of the Japanese Translation of the Parent Overprotection Measure for Mother and Father Reports.

The Parent Overprotection Measure (POM) is a promising scale to measure parent overprotection toward a child from the parent's perspective. However, no Japanese translation of the scale has been developed, and whether the POM can be applied to a Japanese population is unknown. This study translated the POM into Japanese and examined its psychometric properties.

CoDesign of a digital intervention for parents with bipolar disorder informed by integrated knowledge translation principles.

Objectives: To provide detailed information on the codesign of a digital intervention to support parents with bipolar disorder (BD) who have young children. Each step of this process is reported, as well as a detailed description of the final version of the intervention in line with the TIDieR framework.

Methods: Clinical experience and lived experience experts participated in online workshops, meetings, and remote feedback requests, informed by Integrated Knowledge Translation (IKT) principles.

Post-traumatic stress disorder symptoms following exposure to acute psychological trauma in children aged 8-16 years in South Africa: protocol for the Sinethemba longitudinal study.

Introduction: Children exposed to trauma are vulnerable to developing post-traumatic stress disorder (PTSD) and other adverse mental health outcomes. In low-and middle-income countries (LMICs), children are at increased risk of exposure to severe trauma and co-occurring adversities. However, relative to high-income countries, there is limited evidence of the factors that predict good versus poor psychological recovery following trauma exposure in LMIC children, and the role of caregiver support in these high-adversity communities.

Measurement invariance of the higher-order model of Preschool Anxiety Scale (PAS) across child age, gender, parental anxiety, and pandemic period in England.

The Preschool Anxiety Scale (PAS) is a parent-report scale measuring young children's anxiety symptoms involving five specific anxiety symptoms (separation anxiety, physical injury fears, social phobia, obsessive-compulsive disorder, generalized anxiety) that load on a higher-order factor representing general anxiety shared by all specific anxiety symptom subtypes. Although the PAS has been widely used to assess anxiety symptoms in young children, few studies have tested its measurement invariance for group comparisons. Using data from a sample of 2,221 children and their parents/carers in the United Kingdom, this study investigated the measurement invariance of the higher-order model of the PAS across child age (4-6 years vs.

Patterns of sub-optimal change following CBT for childhood anxiety.

Background: Children and adolescents demonstrate diverse patterns of symptom change and disorder remission following cognitive behavioural therapy (CBT) for anxiety disorders. To better understand children who respond sub-optimally to CBT, this study investigated youths (N = 1,483) who continued to meet criteria for one or more clinical anxiety diagnosis immediately following treatment or at any point during the 12 months following treatment.

Methods: Data were collected from 10 clinical sites with assessments at pre-and post-treatment and at least once more at 3, 6 or 12-month follow-up.

Maternal experienced bereavement and offspring mental health in early adulthood: the role of modifiable parental factors.

Background: It is estimated that 78% of children experience the death of a close friend or family member by 16 years of age, yet longitudinal research examining the mental health outcomes of wider experiences of bereavement is scarce. We conducted a longitudinal investigation of the association between maternal experienced bereavement before the age of 11 years and offspring depressive and anxiety disorders at age 18 and examined moderation of this association by modifiable parental factors.

Methods: We analysed data from the Avon Longitudinal Study of Parents and Children, a UK-based birth cohort, including 9,088 child participants with data available on bereavement.

Digitally augmented, parent-led CBT versus treatment as usual for child anxiety problems in child mental health services in England and Northern Ireland: a pragmatic, non-inferiority, clinical effectiveness and cost-effectiveness randomised controlled trial.

Background: Anxiety problems are common in children, yet few affected children access evidence-based treatment. Digitally augmented psychological therapies bring potential to increase availability of effective help for children with mental health problems. This study aimed to establish whether therapist-supported, digitally augmented, parent-led cognitive behavioural therapy (CBT) could increase the efficiency of treatment without compromising clinical effectiveness and acceptability.

Statistical analysis plan for a cluster randomised controlled trial to compare screening, feedback and intervention for child anxiety problems to usual school practice: identifying Child Anxiety Through Schools-identification to intervention (iCATS-i2i).

Background: The Identifying Child Anxiety Through Schools-identification to intervention (iCATS-i2i) trial is being conducted to establish whether 'screening and intervention', consisting of usual school practice plus a pathway comprising screening, feedback and a brief parent-led online intervention (OSI: Online Support and Intervention for child anxiety), bring clinical and health economic benefits compared to usual school practice and assessment only - 'usual school practice', for children aged 8-9 years in the following: (1) the 'target population', who initially screen positive for anxiety problems according to a two-item parent-report child anxiety questionnaire - iCATS-2, and (2) the 'total population', comprising all children in participating classes. This article describes the detailed statistical analysis plan for the trial.

Methods And Design: iCATS-i2i is a definitive, superiority, pragmatic, school-based cluster randomised controlled trial (with internal pilot), with two parallel groups.

Child mental health and income gradient from early childhood to adolescence: Evidence from the UK.

Background: Children from low income families are likely to have poorer mental health than their more affluent peers. However, it is unclear how this association varies at different developmental stages and what the potential underpinning mechanisms are. This study investigates the relationship between family income and mental health problems from early childhood to adolescence in the UK, and examines the potential mediating role of family-related factors over time.

Therapist guided, parent-led cognitive behavioural therapy (CBT) for pre-adolescent children with obsessive compulsive disorder (OCD): a non-concurrent multiple baseline case series.

Background: Cognitive behavioural therapy (CBT) including exposure and response prevention (ERP) is an effective treatment for preadolescent children with obsessive compulsive disorder (OCD); however, there is a need to increase access to this treatment for affected children.

Aims: This study is a preliminary evaluation of the efficacy and acceptability of a therapist-guided, parent-led CBT intervention for pre-adolescent children (5-12 years old) with OCD using a non-concurrent multiple baseline approach.

Method: Parents of 10 children with OCD were randomly allocated to no-treatment baselines of 3, 4 or 5 weeks before receiving six to eight individual treatment sessions with a Psychological Wellbeing Practitioner.

Examining Children and adolescent mental health trajectories during the COVID-19 pandemic: Findings from a year of the Co-SPACE study.

Background: A major concern throughout the COVID-19 pandemic has been on young people's experiences with mental health. In this study we mapped children and adolescents' mental health trajectories over 13 months of the pandemic and examine whether family, peer, and individual-level factors were associated with trajectory membership.

Methods: This study focuses on a sub-sample from the Co-SPACE study of 3322 children and adolescents (aged 4-16 years) for whom parents completed a survey at Time 0 and at least one follow-up survey between March 2020 and May 2021.

The multifaceted consequences and economic costs of child anxiety problems: A systematic review and meta-analysis.

Background: Over a quarter of people have an anxiety disorder at some point in their life, with many first experiencing difficulties during childhood or adolescence. Despite this, gaps still exist in the current evidence base of the multiple consequences of childhood anxiety problems and their costs.

Methods: A systematic review of Medline, PsycINFO, EconLit and the National Health Service Economic Evaluation Database was conducted for longitudinal and economic studies reporting on the association between childhood anxiety problems and at least one individual-, family- or societal-level outcome or cost.

A systematic review and meta-analysis of nonpharmacological interventions for children and adolescents with selective mutism.

Background: Selective mutism (SM) is an anxiety disorder that often starts in early years with serious and lasting consequences. Nonpharmacological interventions are commonly seen as the preferred first treatment. This systematic review identifies outcome measures used and outcomes achieved for nonpharmacological interventions for children and adolescents with SM.

Anxiety disorders in children and adolescents: A summary and overview of the literature.

Considerable work has advanced understanding of the nature, causes, management, and prevention of anxiety disorders in children and adolescents over the past 30 years. Prior to this time the primary focus was on school refusal and specific phobias. It is now recognised that children and adolescents experience the full gamut of anxiety disorders in very similar ways to adults and that anxiety disorders in the paediatric years can predict a lifelong mental-health struggle.

The Effectiveness and Cost-Effectiveness of a Universal Digital Parenting Intervention Designed and Implemented During the COVID-19 Pandemic: Evidence From a Rapid-Implementation Randomized Controlled Trial Within a Cohort.

Background: Children's conduct and emotional problems increased during the COVID-19 pandemic.

Objective: We tested whether a smartphone parenting support app, Parent Positive, developed specifically for this purpose, reversed these effects in a cost-effective way. Parent Positive includes 3 zones.

Barriers and facilitators of community-based implementation of evidence-based interventions in the UK, for children and young people's mental health promotion, prevention and treatment: rapid scoping review.

Background: Community-based organisations continue to take on a greater role in supporting children and young people in the UK with their mental health. However, little evidence exists on the capacity and capability of these settings to effectively implement evidence-based interventions (EBIs).

Aims: To identify barriers and facilitators of the implementation of EBIs within community settings in the UK, for children and young people's mental health promotion, prevention and treatment.

Systematic Review and Meta-Analysis: Risks of Anxiety Disorders in Offspring of Parents With Mood Disorders.

Objective: To examine the risk of anxiety disorders in offspring of parents with mood disorders.

Method: We conducted a systematic review and meta-analysis. We searched 4 electronic databases (Medline, Embase, PsycINFO, and Web of Science [core collection]) to identify cross-sectional and cohort studies that examined the association between parental mood disorders (including bipolar disorder and unipolar depression) and risk of anxiety disorders in offspring.

What Happens to Children's Mental Health and Peer Relationships During Periods of Restricted and Unrestricted Social Interactions? Results From the Co-SPACE Study in Primary School-Aged Children.

Objective: Children's experiences of peer victimization and peer aggression are strongly linked to their mental health. However, we do not know how this relationship is influenced by periods of restricted and unrestricted social interactions. In this study, we investigated the following: (1) the bidirectional association between children's peer problems and mental health; (2) individual differences in the joint development of peer victimization, peer aggression, and mental health; and (3) factors associated with joint trajectories over 13 months during the COVID-19 pandemic in the United Kingdom.
