Theory explains about 25% of variance in behaviour from intention alone, and explains slightly less than 50% of variance in intentions. |

1. 13 studies; 75% of interventions effected a change in behaviour in desired direction. 2. 56 studies; About a third of the variations in behaviour can be explained by the combined effect of intention and perceived behavioural control in the domain of health. 3. 185 independent empirical tests: combined effect of intention and perceived behavioural control explained about a third of variation in behaviour. Theory can explain 20% of prospective measures of actual behaviour. |
