The Vågå Study: an outline of the design.
We carried out an epidemiological study of headache in a rural parish in the mountainous region of southern Norway. During a 2-year period from October 1995, 1838 parishioners in the age range 18-65 (or 88.6% of the target group) were examined in a structured interview based on a questionnaire. The questionnaires were validated in two ways: 100 records were re-checked, with a consistency of 98%, and a re-check of 41 parishioners was carried out > 2 months after the 1st examination. The details of the latter control study will be reported later. Only one result of the study is given: namely, idiopathic stabbing headache ("jabs and jolts syndrome") was present in > 30% of parishioners.
