Study summary

The goal of this observational study is to test the questionnaire CLEFT-Q in a population of patients with cleft lip and/or palate. The main questions it aims to answer are:

  1. Are CLEFT-Q scores reliable over time?
  2. Can CLEFT-Q detect change following surgical treatment intervention?
  3. What is the norm for CLEFT-Q within a control population who do not have cleft lip and/or palate?
  4. What is the Minimal Clinically Important Change of CLEFT-Q in different subpopulations of cleft lip and/or palate?
  5. Do changes in CLEFT-Q scores correlate with changes in objective outcomes following a surgical intervention?
  6. What are the main expectations that patients express before a surgical intervention?
  7. How do patients perceive that the results after surgical interventions meet their expectations?
  8. Do patients express concepts of importance postoperatively that are not examined by CLEFT-Q?
  9. How do healthcare professionals perceive that the use of CLEFT-Q affects clinical decisions and processes?

Participants will

  1. Fill out the questionnaire CLEFT-Q twice with a two-week space.
  2. Before and 1 year after an operation.
  3. Be interviewed about their experiences related to an operation or using CLEFT-Q.

Researchers will compare results from the cleft lip and palate population to see if there is a difference between them and a population without cleft lip and palate.

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 Mar 20, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
