Hypothesis
The study aims to develop a screening instrument for assessing visual complaints in individuals with acquired brain injury (ABI) and evaluate its psychometric properties.
Conclusion
The SVCq-abi shows fundamental psychometric properties and supports a 5-factor structure, indicating it is a valid tool for measuring visual complaints in a community sample.
Supporting Evidence
- A 5-factor structure of the SVCq-abi was adopted which showed an excellent model fit.
- The SVCq-abi subscales demonstrated various floor effects and acceptable scale reliability.
- Moderate to good test-retest reliability was found for the SVCq-abi subscales.
- Convergent validity was established with moderate to strong correlations with the CVSQ.
- Divergent validity showed negligible to moderate correlations with the AQ-short, DASS-21, and BRIEF-A.
Takeaway
This study created a questionnaire to help doctors find out if people with brain injuries have vision problems, which can be hard to notice.
Methodology
A self-report 23-item questionnaire was developed and validated using confirmatory factor analyses on a community sample.
Potential Biases
Potential bias due to self-reporting and the community sample not fully representing the ABI population.
Limitations
The study's findings may not be generalizable to individuals with ABI due to the community sample used, and some items showed floor effects.
Participant Demographics
Mean age of participants was 60 years, with a sample stratified by age and gender.
