Short set of questions on disability: data collection

Recommendations for data collection of the short set of 6 questions devised by the Washington Group for Disability Statistics are given. The questions are phrased to ask whether the subject has difficulty with any of the domains of functioning. They have been field validated. It is recommended that the questions are presented without initial screening questions, that the enumerators are well trained and that the translations from the original English are appropriate. Four domains are highlighted from the 6 if required by space or time.
