An interview to measure vital exhaustion. I. development and comparison with the maastricht questionnaire

Abstract

This article presents an interview designed to measure vital exhaustion (VE), a state characterized by unusual fatigue, increased irritability and feelings of demoralization, which has been found to be a short-term risk indicator of myocardial infarction (MI). This state can be measured by means of the Maastricht Questionnaire (MQ). However, the MQ was found to have some major shortcomings for the selection of subjects for laboratory or clinical investigations. For this reason we designed an interview to assess VE. To test the hypothesis that the interview registers prodromal feelings of MI, the interview was administered to a sample of 81 males who were hospitalized because of a first myocardial infarction (mean age 55.6 years; sd 6.8) and a sample of 168 healthy males (mean age 54.9 years; sd 6.9). Mean scores of cases and controls differed significantly (7.8; sd 6.0 and 3.6; sd 4.0, respectively; t=5.65; p=.000). Mean scores on the questionnaire discriminated significantly too, but the discriminating power was much lower (t=2.31; p=.02). The article gives detailed instructions on the way in which the interview should be administered and scored.
