  We propose a new model for comprehensively monitoring the health status of
individuals by calculating a personal health index. The central framework of
the model is the International Classification of Functioning, Disability and
Health (ICF) developed by the World Health Organization. The model is capable
of handling incomplete and heterogeneous data sets collected using different
techniques. The health index was validated by comparing it to two self-assessed
health measures provided by individuals undergoing rehabilitation. Results
indicate that the model yields valid health index outcomes, suggesting that the
proposed model is applicable in practice.
