Brief Summary

Tics are unwanted, repetitive movements or sounds that are either simple or complex in appearance. Tic disorders often have a huge impact on children's life. The investigators have previously shown a positive outcome of tic training combining habit reversal training (HRT) and exposure response prevention (ERP) either as an individual therapy or in a group setting. However, young people and families are often busy, and having to use a full day as to attend to tic training often is difficult both for the young person and their families. Therefore, the present study focuses on the clinical outcome of combining virtual training with training at the hospital

Detailed Description

Tics are unwanted, brief, repetitive, non-rhythmic movements or sounds that are classified as either simple or complex. Dependent on duration, tics are divided into transient tics and chronic tics. Tic disorders often have an early age of onset and may have a major impact on a young person's life. Treatment of a chronic tic disorder primarily comprises therapeutic intervention which consists of ERP (Exposure Response Prevention) and/or HRT (Habit Reversal Training).

The purpose of the project is to

• Evaluate the treatment outcome of combined video consultation/participating in training sessions at the hospital and of combined self-instructed video training/participating in training sessions at the hospital.
• Compare the treatment outcome of supplementary virtual consultation and supplementary video training via an app with a previous study on the treatment outcome of attending individual therapy (NISSEN, 2018) by means of benchmarking.
• In addition, expound on the significance of sensory modulation (sensitivity), not-just-right experience and the child's perception with regard to the severity of chronic tics and treatment outcome. Also, to investigate whether insight, sensitivity and the not-just-right experience change during treatment.
• As the app is newly developed in relation to the present study, the investigators wish to clarify the participants' evaluation of the app using a newly developed questionnaire (designed for this project). For comparison, a questionnaire has been designed for evaluating the applicability of the supplementary video sessions.

When patients are referred to the Tourette outpatient clinic, Aarhus University Hospital, Psychiatry, a comprehensive diagnostic assessment is carried out. The assessment is based on a modified version of the Schedule for affective disorders and schizophrenia for school-age children - present and lifetime version (K-SADS-PL). The K-SADS-PL information is used for confirming the primary diagnosis of chronic tics and for ensuring that none of the exclusion criteria have been met.

Inclusion criteria

The inclusion criteria are defined based on the ICD-10 diagnosis (International Classification of Diseases and Related Health Problems):

Chronic motor/vocal tics (DF95.1) Tourette syndrome (DF95.2), Age spectrum: 9-17 years old

Exclusion criteria

The exclusion criteria are defined as follows:

Patients with comorbidity such as mental retardation (IQ = 70 or less), psychosis, severe depression requiring treatment, suicidal behavior/threats or severe eating disorder.

Participated in tics training based on HRT/ERP treatment within the last six months.

Oral and written consent will be obtained from parents and children/adolescents (age 15 years and older).

The study will be an open, randomized controlled clinical study for children and adolescents with chronic tics disorders. The participants will be randomized using computer-generated randomization based on age and sex.

The participants will either be randomized for tics training with attendance combined with virtual training (group 1) or a combination of attendance and self-instructed training via videos on an app (group 2). Both settings are based on the "Niks til Tics" manual (NISSEN, 2018) that describes training in Habit Reversal Training (HRT) and Exposure Response Prevention (ERP) over nine sessions. Thus, two treatment groups will be set up:

Group 1 (treatment group 1) will consist of nine entire sessions (60 min each), but where four out of the nine sessions will be converted to video consultations. The content of the video consultations is comparable to the information and training the patients would have received if they attended at the clinic and which are defined in the "Niks til Tics" manual.

Group 2 (treatment group 2) will comprise five entire sessions (60 min) with clinic attendance, but where sessions 1 and 2 will be combined into one session with a duration of 120 min, session 4 will be held as usual with attendance after five weeks, session 8 will be held ten weeks after session 4, and session 9 will be held after two months. In addition, patients in group 2 will be given the opportunity to talk to the therapist on the phone. For the group 2 training sessions, an app has been developed for teaching patients the tics training method. A new app session will be released at each new treatment session, and the content of the app videos will follow the information and training, which the patients would have received if they had attended at the clinic and which are defined in the "Niks til Tics" manual.

All tic training sessions will be individual. The primary outcome goal includes the Yale Global Tics Severity Scale (YGTSS) in session 8. In order to follow the treatment, a parent report questionnaire and a self-report questionnaire will be used and evaluated in accordance with YGTSS (Golden standard). The questionnaires are based on Parent Tic Questionnaire (PTQ). Secondary outcome measures are Screen for Child Anxiety Related Emotional Disorders (SCARED), the Mood and Feelings Questionnaire (MFQ), Premonitory Urge Scale (PUTS), Beliefs About Tics Scale (BATS), NJR-C (not just right experiences), CATS (thoughts about experiences children may be exposed to), W-tc (worrying thoughts) and motivation questionnaire, and the parents are asked to fill in CBCL, BQ (general information) as well as a sensory profile (about hypersensitivity).

Statistical analyses The primary analysis will comprise a comparison of effect sizes within the treatment group, that is, an assessment of the reduction in tic intensity during the eight sessions. The difference in tic intensity between baseline and session 8 will be assessed at t-test. Effect sizes will be calculated by a ratio of the mean difference and the standard deviation of the difference between baseline and session 8 (SD diff). The confidence interval for effect sizes will be calculated using non-parametric bootstrap with 100 replications. At group sizes of 30 with an expected uniform YGTSS baseline of 25 (randomized) and with an expected SD of 6.2 (from a previous study (NISSEN 2018)), and a strength of 0.8 it should be possible to detect a decrease of point 3.4 (from baseline to session 8), which is statistically significant.

Responder level will be defined as a 25% reduction of the YGTSS total tics score.

The secondary analyses will study the reduction in tic intensity between the two treatment groups using unpaired t-test. At a group size of 30 and expected end YGTSS of 15 (SD 6.2) and strength of 0.80 (from a previous study (NISSEN 2018)), a difference of 4.6 between the two groups will be statistically significant.

Predictor analysis: baseline characteristics and baseline tic severity between the two groups will be compared using univariate Chi test for categorical variables and t-tests for continuous variables.

Tic severity will be assessed by independent raters.

Using benchmarking, the results of this treatment study will be compared with the results from a previous treatment study on HRT/ERP (NISSEN, 2018).
