Investigating a therapist-guided, parent-assisted remote digital behavioural intervention for tics in children and adolescents: 'Online Remote Behavioural Intervention for Tics' (ORBIT) trial: protocol of an internal pilot study and single randomised controlled trial

IntroductionTourette syndrome and chronic tic disorder are common, disabling childhood-onset conditions. Guidelines recommend that behavioural therapy should be offered as first-line treatment for children with tics. However, there are very few trained behaviour therapists for tics and many patients cannot access appropriate care. This trial investigates whether an internet-delivered intervention for tics can reduce severity of symptoms.Method and analysisThis parallel-group, single-blind, randomised controlled superiority trial with an internal pilot will recruit children and young people (aged 9-17 years) with tic disorders. Participants will be randomised to receive 10-weeks of either online, remotely-delivered, therapist-supported exposure response prevention (ERP) behavioural therapy for tics, or online, remotely delivered, therapist-supported education about tics and co-occurring conditions. Participants will be followed-up mid-treatment, and 3-, 6-, 12-, and 18-month post-randomisation.The primary outcome is reduction in tic severity as measured on the Yale Global Tic SeverityScale (YGTSS) total tic severity score. Secondary outcomes include a cost-effectiveness analysis and estimate of the longer-term impact on patient outcomes and healthcare services.An integrated process evaluation will analyse quantitative and qualitative data in order to fully explore the implementation of the intervention and identify barriers and facilitators to implementation. The trial is funded by the National Institute of Health Research (NIHR),Health Technology Assessment (16/19/02).Ethics and disseminationThe findings from the study will inform clinicians, healthcare providers and policy makers about the clinical and cost-effectiveness of an internet delivered treatment for children and young people with tics. The results will be submitted for publication in peer-reviewed journals. The study has received ethical approval from North West Greater Manchester Research Ethics Committee (Ref: 18/NW/0079).Trial registration: ISRCTN70758207 and ClinicalTrials.gov (NCT03483493)

The impact of sleep difficulties in children with Attention Deficit Hyperactivity Disorder on the family: A thematic analysis

Background. Attention Deficit Hyperactivity Disorder (ADHD) is a complex but common neurodevelopmental condition characterised by symptoms of inattention, hyperactivity and impulsivity associated with a significant level of academic, social and functional impairment. Problems around sleep frequently co-occur with ADHD and are thought to affect 50-80% of children and adults with the condition. Sleep issues typically include trouble falling asleep, bedtime resistance, night-time waking, and early rising. The impact of these problems on families and parents is profound but poorly researched. Methods. Semi-structured interviews took place with twelve mothers of children with ADHD who struggle with sleep. Participants were asked about sleeping patterns and issues, methods used to improve sleep, the impact on parents’ sleep and wider family life, and involvement with clinical services and support groups. Data were analysed using Thematic Analysis. Results. Three themes were identified in the data: a constant battle ground; the cumulative effect of lack of sleep: impact on functioning and the wider family; a mixed bag of strategies: the tried, tested and needed. Long-term sleep issues and challenging behaviour at bedtime had substantial negative effects on families. Parents experiencing sleep deprivation suffered functional impairments to daily life and wellbeing, and experienced strain on relationships with children and spouses. Conclusions. Findings revealed parents were consistently and profoundly impacted by their children’s sleep problems. Parents sought strategies and support in many different ways but were often unsuccessful

Online remote behavioural intervention for tics in 9- to 17-year-olds: the ORBIT RCT with embedded process and economic evaluation

Background Behavioural therapy for tics is difficult to access, and little is known about its effectiveness when delivered online. Objective To investigate the clinical and cost-effectiveness of an online-delivered, therapist- and parent-supported therapy for young people with tic disorders. Design Single-blind, parallel-group, randomised controlled trial, with 3-month (primary end point) and 6-month post-randomisation follow-up. Participants were individually randomised (1 : 1), using on online system, with block randomisations, stratified by site. Naturalistic follow-up was conducted at 12 and 18 months post-randomisation when participants were free to access non-trial interventions. A subset of participants participated in a process evaluation. Setting Two hospitals (London and Nottingham) in England also accepting referrals from patient identification centres and online self-referrals. Participants Children aged 9–17 years (1) with Tourette syndrome or chronic tic disorder, (2) with a Yale Global Tic Severity Scale-total tic severity score of 15 or more (or > 10 with only motor or vocal tics) and (3) having not received behavioural therapy for tics in the past 12 months or started/stopped medication for tics within the past 2 months. Interventions Either 10 weeks of online, remotely delivered, therapist-supported exposure and response prevention therapy (intervention group) or online psychoeducation (control). Outcome Primary outcome: Yale Global Tic Severity Scale-total tic severity score 3 months post-randomisation; analysis done in all randomised patients for whom data were available. Secondary outcomes included low mood, anxiety, treatment satisfaction and health resource use. Quality-adjusted life-years are derived from parent-completed quality-of-life measures. All trial staff, statisticians and the chief investigator were masked to group allocation. Results Two hundred and twenty-four participants were randomised to the intervention (n = 112) or control (n = 112) group. Participants were mostly male (n = 177; 79%), with a mean age of 12 years. At 3 months the estimated mean difference in Yale Global Tic Severity Scale-total tic severity score between the groups adjusted for baseline and site was −2.29 points (95% confidence interval −3.86 to −0.71) in favour of therapy (effect size −0.31, 95% confidence interval −0.52 to −0.10). This effect was sustained throughout to the final follow-up at 18 months (−2.01 points, 95% confidence interval −3.86 to −0.15; effect size −0.27, 95% confidence interval −0.52 to −0.02). At 18 months the mean incremental cost per participant of the intervention compared to the control was £662 (95% confidence interval −£59 to £1384), with a mean incremental quality-adjusted life-year of 0.040 (95% confidence interval −0.004 to 0.083) per participant. The mean incremental cost per quality-adjusted life-year gained was £16,708. The intervention was acceptable and delivered with high fidelity. Parental engagement predicted child engagement and more positive clinical outcomes. Harms Two serious, unrelated adverse events occurred in the control group. Limitations We cannot separate the effects of digital online delivery and the therapy itself. The sample was predominately white and British, limiting generalisability. The design did not compare to face-to-face services. Conclusion Online, therapist-supported behavioural therapy for young people with tic disorders is clinically and cost-effective in reducing tics, with durable benefits extending up to 18 months. Future work Future work should compare online to face-to-face therapy and explore how to embed the intervention in clinical practice. Trial registration This trial is registered as ISRCTN70758207; ClinicalTrials.gov (NCT03483493). The trial is now complete. Funding This project was funded by the National Institute for Health and Care Research (NIHR) Health and Technology Assessment programme (project number 16/19/02) and will be published in full in Health and Technology Assessment; Vol. 27, No. 18. See the NIHR Journals Library website for further project information. Plain language summary It can be difficult for children and young people with tics to access therapy. This is because there are not enough trained tic therapists. Online remote behavioural intervention for tics was a clinical trial to see whether an online platform that delivered two different types of interventions could help tics. One intervention focused on techniques to control tics; this type of therapy is called exposure and response prevention. The other intervention was psychoeducation, where participants learned about the nature of tics but not how to control them. The online remote behavioural intervention for tics interventions also involved help from a therapist and support from a parent. Participants were aged 9–17 years with Tourette syndrome/chronic tic disorder and were recruited from 16 clinics, two study sites (Nottingham and London) or via online self-referral. All individuals who were eligible for the online remote behavioural intervention for tics trial were randomised in a 50/50 split by researchers who were unaware of which treatment was being given. Participants received either 10 weeks of online exposure and response prevention or 10 weeks of online psychoeducation. A total of 224 children and young people participated: 112 allocated to exposure and response prevention and 112 to psychoeducation. Tics decreased more in the exposure and response prevention group (16% reduction) than in the psychoeducation group (6% reduction) 3 months after treatment. This difference is considered a clinically important difference in tic reduction. The treatment continued to have a positive effect on tic symptoms at 6, 12 and 18 months, showing that the effects are durable. This was achieved with minimal therapist involvement. The cost of online exposure and response prevention to treat young people with tics within this study was less when compared to the cost of face-to-face therapy. The results show that exposure and response prevention is an effective behavioural therapy for tics in this specific patient group. Delivering exposure and response prevention online with minimal therapist contact can be a successful and cost-effective treatment to improve access to behavioural therapy. Scientific summary Background Tic disorders including Tourette syndrome and chronic tic disorders are common conditions that affect approximately 1% of the population in the UK. Young people with tics often report substantial impairment, thus it is important that they have access to evidence-based treatment. Face-to-face behavioural therapy (BT) such as exposure and response prevention (ERP) may be offered to some young people. However, due to a lack of trained therapists, there are often difficulties accessing BT, and there is a better need to understand the clinical and cost-effectiveness of the online delivery of such therapy. Objectives The primary objective of this study was to evaluate the clinical effectiveness of therapist-guided, parent-assisted, internet-based ERP BT for tics in young people with tic disorders compared to online psychoeducation. Secondary objectives included (1) optimising the design of the intervention, (2) undertaking an internal pilot, (3) evaluating cost-effectiveness, (4) establishing whether the efficacy is maintained longer term, (5) understanding the mechanisms of impact of the intervention and (6) identifying barriers to implementation. Methods We conducted an individually randomised (1 : 1 ratio), multicentre trial, with an internal pilot and embedded process evaluation. Participants were assigned to either receive online, remotely delivered, therapist- and parent-supported ERP for tics or online, remotely delivered, therapist- and parent-supported psychoeducation for tics. Participants were recruited from the two study sites, 16 patient identification centres in England or could self-refer online via the study webpage or via Tourettes Action (a national charity for tics). The inclusion criteria were age between 9 and 17 years, with tics assessed on the Yale Global Tic Severity Scale (YGTSS), able to provide written informed consent (parental consent for children aged 80%) was excellent. Retention to the primary outcome measure remained high at 12 months (81% in both arms) and 18 months (> 79% in both arms). The primary analysis showed that participants in the ERP group [16% reduction, standard deviation (SD) 1.1] had a greater decrease in tics than those in the psychoeducation group (6% reduction, SD 1.0) at 3 months (primary end point). The estimated mean difference in YGTSS-TTSS change between the groups adjusted for baseline and site was −2.29 points [95% confidence interval (CI) −3.86 to −0.71] in favour of ERP, with an effect size of −0.31 (95% CI −0.52 to −0.10). This effect was sustained at 6 months, with a mean decrease of 6.9 points (24%, SD 1.2) in the ERP group versus 3.4 points (12%, SD 1.0) in the psychoeducation group. For phase 2, participants in the ERP group continued to have a greater decrease in tics than the control group. The estimated mean difference in YGTSS-TTSS between groups adjusting for baseline and site at 12 months was −2.64 points (95% CI −4.48 to −0.79), with an effect size of −0.36 (95% CI −0.61 to −0.11), at 18 months it was −2.01 points (95% CI −3.86 to −0.15), with an effect size of −0.27 (95% CI −0.52 to −0.02), in favour of the ERP group. In addition, extended follow-up showed those receiving online ERP compared with online psychoeducation had reduced scores for low mood and anxiety at 12 and 18 months and superior tic-specific quality of life, with the largest effects seen at 18 months. The direct cost of the intervention was £155 per person, including £104.57 for the online platform, supervision and training and a mean variable cost of £50.43 per participant for therapist time in the trial. At 18 months, using proxy parent-completed CHU9D responses, there were a mean additional 0.040 (95% CI −0.004 to 0.083) quality-adjusted life-years (QALYs) per participant in the ERP group compared with psychoeducation, with an addition mean cost per participant of £662 (95% CI −£59 to £1384). The incremental cost-effectiveness ratio in the primary analysis was £16,708 per QALY gained from a health and social care cost perspective at 18 months. In the 10-year long-term decision model, online ERP cost £537 less per participant than face-to-face BT and resulted in 0.02 fewer QALYs. Two serious adverse events (SAEs) occurred (hospital attendance due to one ‘collapse’ and one ‘tic attack’), both in the active control psychoeducation group, neither of which were related to the study intervention. The process evaluation found that the ERP intervention was implemented with high fidelity, and participants found the intervention acceptable and satisfactory. Engagement was high, with child participants completing an average of 7.5/10 chapters and 99/112 (88.4%) participants completing the minimum of the first four chapters (the predefined threshold for effective dose). Parental engagement was the only significant independent predictor of child engagement. Improvement in tic severity and overall clinical condition was not moderated by the relationship between demographic or baseline clinical factors and engagement and no mediators were found. However, level of parental engagement was associated with overall clinical improvement, and this relationship was illuminated by the qualitative data. Conclusion Implications for health care The findings demonstrate that online, therapist-supported ERP for young people with chronic tic disorders is clinically effective at reducing tic severity. Therefore, this is an efficient public mental health approach to supporting young people with tics. The intervention can be delivered at lower cost than standard face-to-face BT and may also result in improved service efficiencies, allowing a greater number of young people to access evidence-based care. Future research implications Further ‘field trials’ should be conducted to explore the clinical and service implications of delivering the intervention in real-world settings. Given that online interventions are context dependent, exploring the validity of these findings in different cultures/countries is important. Future research should explore where online, therapist-supported ERP best fits in the tic disorder care pathway and how online and face-to-face therapy can be best combined (e.g. non-responders to online ERP are ‘stepped up’ to face-to-face therapy).
