Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Assessments will be done pre- (T0), and post treatment (T1), and in a follow-up assessment (T2) which is planned 2 months after T0. Key-outcome: tic severity (Yale Global Tic Severity Scale; YGTSS) and premonitory urges (Premonitory Urges for Tics Scale; PUTS). | — |
Secondary
| Measure | Time frame |
|---|---|
| Demographic variables/patient characteristics: semi-structured interview, medical files, psychiatric comorbidities (Anxiety Disorder Interview Schedule; ADIS). Secondary outcomes: - emotional/behavioural functioning, including concentration/attention problems (Child Behavior Checklist; CBCL). - quality of life (Gilles de la Tourette Syndrome Quality of Life Scale for children and adolescents; C&A-GTS-QOL). Feasibility will be assessed by: (1) attendance/drop-out rates, (2) treatment satisfaction forms (parent and child version), specifically designed for this study, (3) semi-structured interviews with stakeholders (children, parents, caregivers and administrators). These assessments give insight into the factors that will enhance or hinder implementation of Tackle your Tics. Key feasibility questions are: What are needs and concerns of participating parents and children? What are the requirements for mental health organisations to apply to this programme? | — |
