title: Causality, linearity, and circularity of relations between stressful life events and pain experience.
abstract: The aim of this paper is to point out a methodological problem found in the 1994 Naidoo and Pillay study on pain experience. The problem is that an equivocal interpretation of cause-and-effect relationships among variables can lead to testing of mistaken hypotheses in later researches.
