Abstract EN
Background.
Missing data are a significant problem in health-related quality of life (HRQOL) research.
We evaluated two imputation approaches: missing data estimation (MDE) and assignment of mean score (AMS).
Methods.
HRQOL data were collected using the Medical Outcomes Trust SF-12.
Missing data were estimated using both approaches, summary statistics were produced for both, and results were compared using intraclass correlations (ICC).
Results.
Missing data were imputed for 21 participants.
Mean values were similar, with ICC >.99 within both the Physical Component Summary and the Mental Component Summary when comparing the two methodologies.
When imputed data were added into the full study sample, mean scores were identical regardless of methodology.
Conclusion.
Results support the use of a practical and simple imputation strategy of replacing missing values with the mean of the sample in cross-sectional studies when less than half of the required items of the SF-12 components are missing.
