Clinicians’ Experiences of an Online Training Programme in Assessing and Treating Body Dysmorphic Disorder in Youth
The global rise in youth mental ill-health is exacerbated by a shortage of clinicians trained in evidence-based care, making it difficult to translate research into effective practice - especially for body dysmorphic disorder (BDD), an adolescent-onset condition that often goes undetected and untreated. This study aimed to explore clinicians' experiences of participation in an online educational programme focused on the assessment and treatment o…
Prevention of Obsessive–Compulsive Disorder in At-Risk Children
Preventing obsessive-compulsive disorder (OCD) before it emerges has long been considered a central, yet elusive, goal for researchers. Achieving this will likely require identifying individuals at elevated risk and intervening during critical developmental periods before the onset of impairing symptoms. This trial evaluated the feasibility of a brief parent-guided online targeted prevention program for children at-risk of developing OCD. We enro…
Stepped Care Versus Stratified Care for Youth with Anxiety Disorders
Anxiety disorders are common in children and adolescents, but access to evidence-based treatment is limited. Most clinical guidelines recommend stratified care, where less complex patients are offered low intensity interventions and complex patients more intensive options. Stepped care, where all patients initially receive low-intensity treatment, has gained traction due to its potential cost-effectiveness. Research on care models for youth with …
The Impact of Pediatric Obsessive-Compulsive Disorder on School Attendance and School Functioning
School-related functional impairment is common in children and adolescents with obsessive-compulsive disorder (OCD). However, little is known about the characteristics of youth with OCD who struggle in school, whether these struggles interfere with treatment outcomes, and whether treatment improves school-related function. Among 385 youth with OCD at a specialist clinic (mean age [sd] = 13.7 [2.5]; 63.1% girls), 21.6% had partial or no school att…
Climate worry
Using an established measure of functional impairment, we found an association of climate worry with functional impairment and PEBs. Importantly, as there is a perceived need for support in individuals with impairment due to climate worry, interventions targeting this specific subgroup should be developed
Focusing on Comorbidity—A Novel Meta-Analytic Approach and Protocol to Disentangle the Specific Neuroanatomy of Co-occurring Mental Disorders
The novel approach is a valid method to focus on comorbidities. The meta-analysis will yield a comprehensive atlas of the neuroanatomy of all major mental disorders and their comorbidities, which we hope might help develop potential diagnostic and therapeutic tools
The Covid-19 pandemic and its impact on tic symptoms in children and young people
To understand how children and young people with tic disorders were affected by COVID-19, we compared pre and during pandemic scores on the Yale Global Tic Severity Scale (YGTSS). Participants were young people (N = 112; male:78%; 9-17 years) randomised to the control arm of the "ORBIT-Trial" (ISRCTN70758207, ClinicalTrials.gov-NCT03483493). For this analysis, the control arm was split into two groups: one group was followed up to 12-months' post…
Psychometric Evaluation of the Yale-Brown Obsessive-Compulsive Scale Modified for Body Dysmorphic Disorder for Adolescents (BDD-Ybocs-A)
The Yale-Brown Obsessive-Compulsive Scale Modified for Body Dysmorphic Disorder for Adolescents (BDD-YBOCS-A) is a clinician-rated measure of BDD symptom severity in youth. Despite widespread use in both research and clinical practice, its psychometric properties have not been formally evaluated. The current study examined the factor structure, reliability, validity, and sensitivity to change of the BDD-YBOCS-A in 251 youths with BDD attending tw…
A Two-to-Five Year Follow-Up of a Pediatric Acute-Onset Neuropsychiatric Syndrome Cohort
Little is known about the long-term prognosis of children with pediatric acute-onset neuropsychiatric syndrome (PANS). Out of the 46 eligible patients from the Karolinska PANS cohort, 34 consented to participate in a follow-up (median 3.3 years). Participants underwent a thorough clinical evaluation and were classified according to their clinical course. Resulting groups were compared on clinical characteristics and laboratory test results. We ob…
The Cost of Obsessive–Compulsive Disorder in Swedish Youth
The economic impact of pediatric obsessive-compulsive disorder (OCD) on society is unknown. We compared a wide range of individual-level cost data of children 7-17 years with OCD (n = 152) with a control group from the general population in Sweden (n = 768). The total annual cost in the OCD group was M = 11941€ (95%CI [9915-13966]), compared to the control group M = 6380 € (95%CI [5461-7299]), corresponding to an estimated marginal mean cost of O…
The Work and Social Adjustment Scale, Youth and Parent Versions
The Work and Social Adjustment Scale (WSAS) is a brief global measure of functional impairment that is widely used in adult health. We have adapted the WSAS for its use in youth, the WSAS-Youth version (WSAS-Y) and WSAS-Parent version (WSAS-P). This study evaluated the psychometric properties of the scale. The internal consistency, factor structure, convergent and divergent validity, test-retest reliability and sensitivity to change of the WSAS-Y…
Effectiveness of Behaviour Therapy for Children and Adolescents with Tourette Syndrome and Chronic Tic Disorder in a Naturalistic Setting
It is unclear if the results of randomised controlled trials (RCTs) of behaviour therapy (BT) for Tourette syndrome (TS) and chronic tic disorder (CTD) can be generalised to naturalistic clinical settings and are durable long-term. In this naturalistic study, 74 young people with TS/CTD received BT at a specialist clinic. Data were collected at baseline, post-treatment, and at 3-, 6-, and 12-month follow-ups. Measures included the Yale Global Tic…
A transcultural study of hoarding disorder
Though problematic hoarding is believed to be a universal human behavior, investigations of clinically-defined hoarding disorder (HD) have been confined almost exclusively to Western countries. The current investigation sought to describe and directly compare the features of individuals meeting diagnostic criteria for HD across four distinct cultural settings. Participants were 82 individuals meeting DSM-5 diagnostic criteria for HD, recruited an…
Probing the Working Memory System in Chronic Fatigue Syndrome
Objective: Up to 90% of patients with chronic fatigue syndrome (CFS) report substantial cognitive difficulties. However, objective evidence supporting these claims is inconsistent. The present functional magnetic resonance imaging study examined the neural correlates of working memory in patients with CFS compared with controls. Methods: Seventeen patients with CFS and 12 healthy control subjects were scanned while performing a parametric version…
