Does changing behavioral intentions engender behavior change? A meta-analysis of the experimental evidence
Webb and Sheeran meta-analysed 47 experimental tests of whether changing behavioural intentions changes behaviour. Interventions produced a change in intention of d = 0.66, a medium-to-large effect, and a change in behaviour of d = 0.36, a small-to-medium effect.
