Epilepsy and quality of life in adults: A review of instruments

We classified questionnaires according to three aspects: validation, diffusion of use, and specificity of domains. Questionnaires covering all three aspects (WPSI, ESI-55, QOLIE-89, QOLIE-31, QOLIE-10, Liverpool Batteries) should be preferred when planning a QoL study in epilepsy. However, those covering only two aspects (SF-36, SEALS, EPSES, EOS, PESOS, QOLAS) could also be useful in selected situations or may become a first-choice instrument in the future, after more widespread use or complete validation. All the other instruments should at present be considered only for second choice.
