Predicting and explaining transtheoretical model stage transitions in relation to condom-carrying behaviour.

Abstract

The stages of change component of the transtheoretical model have been applied to safe sex behaviours in cross-sectional analyses, but have not yet been subject to prospective analysis. It was predicted that: (a) cross-sectional analyses would demonstrate good discrimination between the stages of change; (b) prospective analyses would allow for the identification of predictors of stage transitions; and (c) implementation intentions would explain progression from the preparation stage.
