In the motivation phase, the individual forms an intention to either adopt a precaution measure or change risk behaviours in favour of other behaviours. Self-efficacy and outcome expectancies are seen as the major predictors of intentions. Most previous models treat these two as being unrelated predictors. However, there might be a temporal and causal order among them. Outcome expectancies can be seen as precursors of self-efficacy because people usually make assumptions about the possible consequences of behaviours before inquiring whether they can really take the action themselves. If self-efficacy is specified as a mediator between outcome expectancies and intention, the direct influence of outcome expectancy on intention may dissipate. But the research findings on this issue are very inconsistent, rendering both cognitions primary candidates for motivating change. Under conditions where individuals have no experience with the behaviour they are contemplating, we assume that outcome..
