About this study

This study aimed to evaluate the validity of the Chinese translation version of OSDI-6 (C-OSDI-6) in a theoretical set-up of two questionnaire groups for dry eye

Read the detailed description

Screening for dry eye symptoms and quantifying dry eye symptoms aids in assessment, diagnosis, and treatment. Patient-reported outcome (PRO) instruments such as the Ocular Surface Disease Index (OSDI-12) are utilized for assessing patients' subjective experiences and functional abilities. The OSDI-12 comprises of 12-item and is often used in conjunction with other tests in clinical settings to assess individuals with DE. Created in 1997, the original OSDI consisted of 12 items and was designed to evaluate subjective dry eye symptoms and the consequences of DED on vision-related activities of daily life over the preceding week. The 12 items are grouped into three subscales: ocular symptoms (three items), vision-related functions (six items), and environmental triggers (three items). While the original version of the OSDI-12 questionnaire was created in English and was later translated and validated into other languages, it should be used carefully since the cutoff values vary among various languages (27.2 points for the Chinese version and 36.3 points for the Japanese version) . Recent research using Rasch analysis found that separating answer items into four categories by merging "half of the time" and "most of the time" might lead to higher thresholds and better intervals in each category. The OSDI-12 total score is calculated using the formula: [(sum of scores for all questions answered) × 100]/ [(total number of questions answered) × 4]. Ocular Surface Disease Index-6 (OSDI-6) is a derivative and shortened version of the original OSDI-12 and can potentially improve efficiency in a busy clinical setting.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. OSDI12

    The patient will answer each question on a scale ranging from 0 to 4, with 0 indicating 'none of the time' and 4 indicating 'all of the time'. If a certain question is deemed irrelevant, it will be marked as 'not applicable (N/A)' and excluded from the analysis. The OSDI total score is calculated according to the following formula. The scale ranges from 0 to 100, with higher scores representing more severe cases of dry eye syndrome

    Measured: Baseline

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

OSDI12 (time frame: Baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06158906, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Feb 2024.
