Key result
Telephonic KnGOS-E demonstrates excellent reliability versus face-to-face assessment in TBI survivors.
Why the study?
Telephone interviews offer a practical substitute for face-to-face evaluations in India, motivating the validation and reliability testing of the Kannada-translated Glasgow Outcome Scale-Extended.
Does telephonic administration of the Kannada GOS-E provide reliable scores compared to face-to-face administration in TBI survivors?

The Kannada version of the GOS-E can be reliably administered via telephone, offering a practical alternative to face-to-face assessments for TBI survivors in resource-limited settings.
Background: Glasgow Outcome Scale-Extended (GOS-E) is commonly used to evaluate outcomes after traumatic brain injury (TBI). In India, where many patients live distant from medical facilities, telephone interviews offer a practical substitute for face-to-face evaluations. Objective: This study aimed to validate the Kannada version of GOS-E and investigate the intermethod reliability of the Kannada-translated GOS-E (KnGOS-E) in TBI survivors at and after 3 months of injury, comparing telephonic and face-to-face administration methods. Materials and Methods: A total of 15 TBI subjects were recruited based on specific inclusion criteria. Two raters conducted the assessments: the primary rater recorded KnGOS-E scores during a face-to-face interview, followed by a telephonic assessment by the second rater after 3 weeks. Results: The study found that TBI was more prevalent among males, with a mean age of 36.9 ± 13.02 years. The inter-rater reliability between telephonic and face-to-face KnGOS-E assessments was excellent, with a weighted kappa of 0.92 (95% confidence interval: 0.78–1.00, P < 0.001). Conclusion: The findings indicate that the GOS-E can be reliably administered through telephone in TBI survivors, providing a practical alternative to face-to-face assessments in resource-limited settings.

Dcosta et al. (2025) conducted a cross-sectional in Traumatic brain injury (TBI) (n=15). Telephonic administration of Kannada-translated GOS-E vs. Face-to-face administration was evaluated on Inter-rater reliability between telephonic and face-to-face KnGOS-E assessments (weighted kappa 0.92, 95% CI 0.78-1.00, p=<0.001). Telephonic administration of the Kannada-translated GOS-E showed excellent inter-rater reliability compared to face-to-face assessment in TBI survivors (weighted kappa 0.92; 95% CI 0.78-1.00; P<0.001).
