About this study
Official title: Visual, Ocular Surface and Extraocular Diagnostic Criteria for Prevalence of Computer Vision Syndrome: A Cross-sectional Smart-survey Based Study
CVS-F4 questionnaire will be used as an instrument to survey CVS prevalence and severity among medical students
Read the detailed description
CVS-F4 (30 questions) will be an online survey via the SurveyMonkey Company. We will collect the responses and analyze the results. Informed consent will be obtained from the participants as an item within the survey itself that he/she agrees to use his/her data in this research work. The questionnaire includes questions regarding potential ocular, extra-ocular, musclo-skeletal and neuro-psychatric complains caused by CVS. Complete statistical analysis of the survey data will be done using univariate and multivariate logistic and linear regression analysis. The CVS diagnosis will be based on the 5 diagnostic criteria (5DC) to create a new short self-assessment questionnaire for accurate prevalence of CVS.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CVS GroupBehavioural
CVS-F4 will be an online survey via the SurveyMonkey Company. The participants will report their potential CVS complains and associated screen factors as screen-time, screen-size, screen-resolution and other factors. We will collect the responses and analyse the results. Informed consent will be obtained from the participants as an item within the survey itself that he/she agrees to use his/her data in this research work. This group will contain participants with CVS complains.

|---|---|---|
| Control Group | The participants will respond to CVS-F4 questionnaire online via SurveyMonkey to report their potential CVS complains and associated screen factors as screen-time, screen-size, screen-resolution and other factors. This group will contains participants with no CVS complains. Receives: Behavioral: CVS Group |

The record lists 2 sites in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Number of participants suffering from CVS (time frame: 3 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 29 May 2024.
