Study summary

The goal of this qualitative study is to understand the challenges of stigmatization and discrimination in children and young adults with Chronic Tic Disorders (CTD), including Tourette Syndrome. Measuring and understanding how stigma affects those with CTD will help inform future work.

Read the detailed description

This study will utilize a phased approach, where (1) Narrative and thematic content data will be obtained through in-depth qualitative interviews of CTD stakeholders. (2) Based on these results, a novel scale will be developed through the Delphi Method with CTD stakeholders. (3) Preliminary analyses of the scale's psychometric properties.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

DSM diagnostic criteria

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

Groups and cohorts

  • Youth with CTD Ages 8-12

    Youth (8-12 years) will be recruited for a qualitative interview using the exploratory questionnaire developed for the study. Parent/caregivers will also be asked questions related to their child's CTD. Participants will be asked for feedback on the ease of completion, content, readability and completion time. After development of the TD Stigma scale, prior and new participants with CTD will be asked to complete the TD-Stigma scale with companion measures. Feedback on the scale will be elicited as well.

  • Supporters: Parents/Caregivers

    Qualitative interviews will be administered and adapted to the caregiver's perspective. Parents/caregivers will also be asked to complete questionnaires child's CTD history, family history and impact of CTD on different aspects of the child's life. Participants will be asked for feedback on the ease of completion, content, readability and completion time.

  • Provider/ advocate cohort

    For providers and advocates, qualitative interview administered will begin with the participant's experience and qualifications in caring for individuals with CTD and adapted to the provider's perspective. Participants will be asked for feedback on the ease of completion, content, readability and completion time.

  • Youth with CTD Ages 13-17

    Youth (13-17 years) will be recruited for a qualitative interview using the exploratory questionnaire developed for the study. Parent/caregivers will also be asked questions related to their child's CTD. Participants will be asked for feedback on the ease of completion, content, readability and completion time. After development of the TD Stigma scale, prior and new participants with CTD will be asked to complete the TD-Stigma scale with companion measures. Feedback on the scale will be elicited as well.

  • Adults with CTD Ages (18-30)

    Adults with CTD (Ages 18-30) will be recruited for a qualitative interview using the exploratory questionnaire developed for the study. Participants will be asked for feedback on the ease of completion, content, readability and completion time. After development of the TD Stigma scale, prior and new participants with CTD will be asked to complete the TD-Stigma scale with companion measures. Feedback on the scale will be elicited as well.

  • Supporters: Partners/Spouses/Significant others

    For Partners/Spouses/Significant others, qualitative interview administered will begin with the participant's experience and qualifications in caring for individuals with CTD and adapted to the supporter's perspective. Participants will be asked for feedback on the ease of completion, content, readability and completion time.

What researchers measure

Primary outcomes

  1. Change in Tourette Discrimination-Stigmatization (TD-STIGMA) scores

    Confirmatory factor analysis will be used to assess the factor structure of the hypothesized domains. Mean TD-STIGMA scores will be calculated. Internal consistency (both overall and within each domain) will be evaluated using Cronbach's alpha. Intraclass correlation will be used to evaluate test-retest reliability by retesting a subset of participants (n=20) two weeks after test administration. Some items may be removed from the list based on the results of the factor analysis, internal consistency, and test-retest evaluation. Both convergent validity and known-group validity will be evaluated. Analyses will use SAS 9.3.

    Time frame: Month 7

Other outcomes

  1. Qualitative Interviews

    Stakeholder interviews will be audio-recorded, transcribed, and input into NVivo software for qualitative analysis. Transcripts will be compared with original recordings to ensure accuracy. Interviews will be analyzed using deductive thematic content analysis practices to identify emerging themes and subthemes.

    Time frame: 3 hours

  2. Tourette Discrimination-Stigmatization (TD-STIGMA) Scale psychometric properties

    A de-identified summary document of thematic content and narrative content analysis from Aim 1 will be securely emailed to stakeholders. Content will be alphabetized to avoid introducing bias. Stakeholders will be blind-copied to maintain anonymity. Using the Delphi Method, they will be asked to prioritize responses, provide feedback and propose solutions. The feedback process will continue until there is an 80% consensus among stakeholders. The outcome will be a close-ended TD-STIGMA scale. The Flesch Reading Ease score and Flesch-Kincaid Grade level will be used to assess questionnaire readability.

    Time frame: Month 4

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 10, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
