Internet-delivered CBT for children with anxiety disorders : effect and prerequisites for implementation within public health care
Background: Anxiety disorders are among the most common mental health problems in
children and, if left untreated, increase the risk of impairment and psychiatric illness in the
future. Although cognitive behavior therapy (CBT) is a recommended treatment for pediatric
anxiety disorders, a large proportion of children do not receive CBT. Internet-delivered CBT
(ICBT) is an effective treatment for a range of psychiatric disorders in adults and could be a
way of increasing availability to treatment for children.
Aims: The aim of the present thesis was to develop and evaluate ICBT for children (8-12
years of age) with a diagnosed anxiety disorder, and to investigate important prerequisites for
implementation within regular health care. Specifically, we aimed to investigate the efficacy
and feasibility of ICBT for children with specific phobia (study I), evaluate the effect of
ICBT for children with anxiety disorders (study II), explore the long-term effects of ICBT
(study III), investigate potential predictors of treatment outcome (study III), and explore
clinicians attitudes to ICBT for children and adolescents (study IV).
Methods: A technical platform for delivering treatment over the internet and a therapistguided
CBT-based treatment program was developed. To test the preliminary feasibility and
effect of ICBT, study I included 30 families with a child with a principal diagnosis of specific
phobia. They received ICBT for six weeks and were assessed post-treatment and threemonths
later. Study II randomized 93 families with a child with an anxiety disorder to either
ICBT or a waitlist control condition. All participants were assessed ten weeks later, and those
randomized to ICBT were also assessed three months after post-treatment. Study III was a
long-term follow-up (3 and 12 months) of participants in study II, and included analyses of
outcome predictors. Study IV was a survey study conducted at 15 randomly selected
CAMHS-units in Sweden, with a total of 156 participating clinicians.
Results: Studies I and II showed large within-group effects on clinician rated symptom
severity and moderate effects on parent-rated child anxiety. Study II showed that the ICBT
group had improved significantly more than the waitlist group at post-treatment.
Improvements in the ICBT group continued until three- and twelve-month follow-up (study IIII).
About a fifth of those who received ICBT did not fulfill criteria for their principal
anxiety disorder at post-treatment, and this proportion increased to about 50% at three-month
follow-up (studies I-III). In study IV, we found that clinicians reported seeing several
advantages with ICBT and would consider using ICBT for children with mild to moderate
problems.
Conclusions: Guided ICBT for children with anxiety disorders could be effective in reducing
clinician- and parent-ratings of anxiety. ICBT seems to be a promising method, although
there is room for improvement. Most clinicians within Swedish CAMHS-units were largely
positive towards using ICBT with children and adolescents, especially for mild to moderate
problems. Thus, ICBT holds promise for future implementation within regular health care
Internet-delivered cognitive behavior therapy for adolescents with irritable bowel syndrome : a randomized controlled trial
OBJECTIVES: Few treatments have been able to effectively manage pediatric
irritable bowel syndrome (IBS). Internet-delivered cognitive behavior therapy
(Internet-CBT) based on exposure for abdominal symptoms is effective for adult
IBS. The objective of this study was to evaluate the efficacy of Internet-CBT
based on behavioral exposure for adolescents with IBS. METHODS: Adolescents with
IBS fulfilling the Rome III criteria were randomized to either Internet-CBT or a
wait-list control. The Internet-CBT was a 10-week intervention where the main
component was exposure to IBS symptoms by reduction of avoidance of abdominal
symptoms and instead stepwise provocation of symptoms. The primary outcome was
total score on Gastrointestinal Symptoms Rating Scale for IBS (GSRS-IBS).
Secondary outcomes included adolescent- and parent-rated quality of life and
parent-rated gastrointestinal symptoms. Difference between groups was assessed
from pretreatment to posttreatment and the Internet-CBT group was also evaluated
at 6 months after treatment completion. RESULTS: A total of 101 adolescents with
IBS (13-17 years of age) were included in this study. Dropout rates were low (6%)
and all randomized patients were included in intent-to-treat analyses based on
mixed effects models. Analyses showed a significant larger pretreatment to
posttreatment change on the primary outcome GSRS-IBS (B=-6.42, P=0.006, effect
size Cohen's d=0.45, 95% confidence interval (0.12, 0.77)) and on almost all
secondary outcomes for the Internet-CBT group compared with the control group.
After 6 months, the results were stable or significantly improved. CONCLUSIONS:
Internet-CBT based on exposure exercises for adolescents with IBS can effectively
improve gastrointestinal symptoms and quality of life.Jane and Dan Olsson foundation, 4-1559/2013Kempe-Carlgrenska foundationRuth and Richard Julin foundation, 2012Juli0048Ishizu Matsumurais DonationMajblomman foundationBengt Ihre research fellowshipBengt Ihre foundation, SLS-331861The Samariten foundationThe Swedish society of medicine, SLS-331681, SLS-410501VärkstadststiftelsenGadelius foundationSwedish Research Council, 521-2013-2846Regional agreement on medical training and clinical research between Stockholm County Council and Karolinska Institutet, 20130129Accepte
Efficacy and cost-effectiveness of therapist-guided internet cognitive behavioural therapy for paediatric anxiety disorders : a single-centre, single-blind, randomised controlled trial
Background: Paediatric anxiety disorders are prevalent and associated with substantial disability and long-term adverse consequences. Only a minority of affected children have access to evidence-based treatment; internet-delivered cognitive behaviour therapy (ICBT) could help increase accessibility but needs further rigorous evaluation. The objective of this trial was to evaluate the clinical efficacy and cost-effectiveness of ICBT in the treatment of paediatric anxiety disorders.
Methods: In this single-blind randomised controlled trial, children 8-12 years with a principal anxiety disorder diagnosis were randomly allocated (1:1) to ICBT or internet-delivered child-directed play (ICDP), an active comparator aimed to improve parent-child relationships and increase child self-esteem without directly targeting anxiety. The study was conducted at a single site within the Stockholm specialist child and adolescent mental health services (CAMHS). Primary endpoint was clinician-rated symptom severity (CSR) of the principal anxiety disorder at post-treatment. All participants were included in the primary analysis (intent-to-treat). Trial registration number: NCT02350257.
Findings: Participants (N=131) were recruited between March 2015 and October 2016, mainly via advertisement and referrals from CAMHS, and allocated to ICBT (n=66) or ICDP (n=65). Analyses revealed greater reduction of symptom severity in favour of ICBT (mean difference 0·79, 95% CI 0·42 to 1·16, p=0·002; Cohen’s d=0·77, 95% CI 0·40 to 1·15) and at post-treatment, 48% (n=29) of participants randomised to ICBT no longer fulfilled their principal diagnosis, compared to 15% (n=9) in ICDP (odds ratio 5·41, 95% CI 2·26 to 12·90, p<0·0001). Numbers needed to treat were 3 (95% CI 2·85 to 3·15). Treatment gains were maintained at 3-month follow-up, at which point 70% (n=40) of participants randomised to ICBT no longer met the criteria for their principal anxiety disorder. ICBT resulted in an average societal cost saving of €493·05 (95% CI 477·17 to 508·92) per participant. No severe adverse events were reported.
Interpretation: ICBT is a cost-effective treatment for paediatric anxiety disorders that should be considered for implementation in routine clinical care.The Swedish Research Council for Health, Working Life and WelfareStockholm County CouncilAccepte
Research Review: Recommendations for reporting on treatment trials for child and adolescent anxiety disorders - an international consensus statement
Background:
Anxiety disorders in children and young people are common and bring significant personal and societal costs. Over the last two decades, there has been a substantial increase in research evaluating psychological and pharmacological treatments for anxiety disorders in children and young people and exciting and novel research has continued as the field strives to improve efficacy and effectiveness, and accessibility of interventions. This increase in research brings potential to draw together data across studies to compare treatment approaches and advance understanding of what works, how, and for whom. There are challenges to these efforts due largely to variation in studies' outcome measures and variation in the way study characteristics are reported, making it difficult to compare and/or combine studies, and this is likely to lead to faulty conclusions. Studies particularly vary in their reliance on child, parent, and/or assessor-based ratings across a range of outcomes, including remission of anxiety diagnosis, symptom reduction, and other domains of functioning (e.g., family relationships, peer relationships).
Methods:
To address these challenges, we convened a series of international activities that brought together the views of key stakeholders (i.e., researchers, mental health professionals, young people, parents/caregivers) to develop recommendations for outcome measurement to be used in treatment trials for anxiety disorders in children and young people.
Results and conclusions:
This article reports the results of these activities and offers recommendations for selection and reporting of outcome measures to (a) guide future research and (b) improve communication of what has been measured and reported. We offer these recommendations to promote international consistency in trial reporting and to enable the field to take full advantage of the great opportunities that come from data sharing going forward
Att mäta psykologisk flexibilitet hos barn och ungdomar med långvarig smärta - En pilotstudie
Development of the Spence Children’s Anxiety Scale - Short Version (SCAS-S)
The literature provides several examples of anxiety symptoms questionnaires for children. However, these questionnaires generally contain many items, and might not be ideal for screening in large populations, or repeated testing in clinical settings. The Spence Children’s Anxiety Scale (SCAS) is an extensively used and evaluated 44-item questionnaire developed to assess anxiety symptoms in children, and provides a sound base for the development of an abbreviated anxiety symptoms questionnaire. Although methodological standards have been presented in how to develop abbreviated questionnaires, previous studies have often suffered from several limitations regarding validating procedures. Guided by these methodological standards, the current study aimed at developing an abbreviated version of the SCAS, while retaining the content, convergent, and divergent validity of the original scale. A school-based sample (n = 750) was used to reduce the number of items, and an independent school-based sample (n = 371) together with a clinical sample (n = 93), were used to validate the abbreviated scale. The abbreviated version of the SCAS contained 19 items, it showed a clear factor structure as evaluated in the independent sample, and it performed as good as the original questionnaire regarding classification accuracy, convergent, and divergent validity. In our view, the abbreviated version is a very good alternative to the original scale especially for younger children, in initial screening, or in order to reduce response burden
"On My Own, but Not Alone" - Adolescents' Experiences of Internet-Delivered Cognitive Behavior Therapy for Obsessive-Compulsive Disorder.
INTRODUCTION:Childhood Obsessive-Compulsive Disorder (OCD) is a prevalent and impairing condition that can be effectively treated with Cognitive Behavior Therapy (CBT). However, a majority of children and adolescents do not have access to CBT. Internet-delivered CBT (ICBT) has been suggested as a way to increase availability to effective psychological treatments. Yet, the research on ICBT in children and adolescents has been lagging behind significantly both when it comes to quantitative as well as qualitative studies. The aim of the current study was to describe the experience of ICBT in adolescents with OCD. METHOD:Eight adolescents with OCD that had received ICBT were interviewed with qualitative methodology regarding their experiences of the intervention. Data was summarized into thematic categories. RESULTS:Two overarching themes were identified, autonomy and support, each consisting of three primary themes (self-efficacy, flexibility, secure self-disclosure and clinician support, parental support, identification/normalization, respectively). CONCLUSIONS:The experiential hierarchical model that was identified in this study is, in part, transferrable to previous research. In addition, it highlights the need of further study of important process variables of ICBT in young patient populations
Intolerance of uncertainty-focused treatment for adolescents with excessive worry - A pilot feasibility study
Bouts of excessive worry are common across the lifespan, increasing in frequency and complexity during adolescence and adulthood, and are found in several psychiatric disorders, particularly the anxiety disorders. There are evidence-based treatments for adolescents with anxiety disorders but psychological treatments designed specifically to target excessive worrying in adolescents are rare. Intolerance of uncertainty (IU), a cognitive predisposition described as a fear of the unknown, is highly associated with worry among adolescents. This study investigated the feasibility, acceptability, and preliminary efficacy of IU-focused cognitive behavioral therapy (IU-CBT) for adolescents with excessive worry. Twelve participants (aged 13–17 years) with excessive worry, irrespective of psychiatric diagnosis, were provided weekly face-to-face sessions, primarily including therapist and self-guided exposure to situations involving uncertainty. Sessions were supplemented with an internet-delivered educational program for parents, designed to teach parents about worry, IU and helpful parental behaviors. The main outcome measure was the Penn-State Worry Questionnaire for Children (PSWQ-C). The treatment was well tolerated with no dropouts and families reporting being satisfied with the treatment. Participants were able to grasp the notion of IU and its relationship to worry and avoidance. Significant reductions were observed for self-reported worry, anxiety, depression, IU, and parent-reported worry, as were significant increases in global functioning. Based on a clinician rating, 58.3% were categorized as much or very much improved at posttreatment, rising to 66% at 3-month follow-up. Participants with generalized anxiety disorder (GAD) benefitted more from treatment than those with social anxiety disorder. The findings suggest that this IU-focused psychological intervention is acceptable and feasible to adolescents with excessive worry but may be most effective for those with GAD

“Therapy without a therapist?” The experiences of adolescents and their parents of online behavioural activation for depression with and without therapist support
Behavioural Activation (BA) is an established treatment for adults with depression, and research on BA for adolescents is promising. However, there is a knowledge gap in terms of the experiences of adolescents and their parents BA for depression delivered online. Furthermore, there have been no previous studies conducted on the experiences of respondents with regard to the role of the therapist in online treatment. Therefore, the primary aim of this study is to explore the experiences of online BA among adolescents with depression and how their parents experience supporting their adolescent through treatment. Second, the experiences of having online therapy with or without a therapist were explored. Semi-structured interviews were conducted with eight adolescents and nine parents (n = 17) who completed guided or self-guided online BA. Reflexive thematic analysis was used to identify aspects of the experience of treatment that were important to adolescents and their parents. Two main themes were generated: (1) opportunities or barriers to engaging in treatment and (2) parental involvement is valued and welcomed. This study contributes valuable information regarding user experiences of BA treatment, the importance of therapist support and parental involvement in treating adolescents with depression.
