The Mental Vulnerability Questionnaire was originally a 22 item scale, later reduced to a 12 item scale. In population studies the 12 item scale has been a significant predictor of health and illness.

Methods: Of 740 persons (aged 25 to 64 years) examined in a 1989 Danish cross-sectional headache study, 673 were eligible for follow-up in 2001. All interviews at baseline and at follow-up were conducted by medical doctors and based on the 1988 IHS-criteria.
Objective: The present study aims to compare the prevalence of primary headaches in Denmark in two periods as only few replicate studies have re-evaluated the prevalence of primary headaches.
Study Design And Setting: The 2001 study is a replicate of a cross-sectional survey of primary headaches in 1989, and compares 297 subjects aged 25-36 years from the general population, with the 294 comparable subjects invited in 1989. Medical doctors diagnosed all headaches using IHS-classification.
