Detecting measurement confounding in epidemiological research: construct validity in scaling risk behaviours: based on a population sample in Minnesota, USA

摘要

Conclusions-The risk behaviour do not represent sufficiently similar types of phenomena to form an additive scale of health related risk taking. Not only do the practices fall on different, undefined di- mensions of behaviour, subgroup differ- ences in risk taking would be hidden by data reductions summing the behavioural practices into additive scales. The findings indicate that the behaviours have quite distinct meanings that should be studied separately. Study objective-The purpose of this Study was to construct and validate a Behavioural risk index scale to determine If the scaled variable could be used to Study possible latent dimensions of risk Behaviour.
