1. 46 studies- substantial empirical support.
2. 16 studies; at best 10% of variance accounted for by any one dimension of the theory.
SCT Bandura 1950's 38 27 studies; self-efficacy explained between 4% and 26% of variance
TRA Fishbein & Ajzen, 1975 41 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.

1. Stage based interventions not more effective at increasing smoking cessation than non-stage based interventions.
2. 91 independent samples. Results support that individuals use all 10 processes of change.
