title: The Environmental Symptoms Questionnaire in acute mountain sickness.
abstract: A self-completed questionnaire (modified Environmental Symptoms Questionnaire) was evaluated in a study of acute mountain sickness (AMS). The questionnaire scores for headache, nausea, and the general feeling of ill health correlated well with AMS scores obtained by clinical interview. Modifications in the instructions and the phrasing of some of the questions are suggested and we doubt whether factor analysis provides any better data than more simple statistical methods. The questionnaire is a useful additional method for the assessment of symptoms of AMS.
