✦ Synopsis

This paper arues that empirical\ conceptual\ and statistical dif\_culties characterise previous demonstrations that self!schemas moderate the relationship between intentions and behaviour[ A lonitudinal study "n 052# was desined to overcome limitations of previous research[ Theory of planned behaviour variables\ past behaviour\ and self!schemas were assessed in relation to exercise[ Behaviour was followed up two weeks later[ Findins showed that self!schemas moderated the intentionÐbehaviour relation such that schematics were more likely to enact their intentions to exercise compared to unschematics[ Evidence su``ested that the importance dimension of self!schema measures was responsible for the moderator effect[ Self!schemas were also associated with improved prediction of behavioural intentions after controllinfor the other predictors [ Copyriht Þ 1999 John Wiley + Sons\ Ltd[ The purpose of the present research is to explore the implications of self!schemas "Markus\ 0866# for the theory of reasoned action and the theory of planned behaviour[ In particular\ we examine whether having a self!schema in a domain is associated with greater consistency between intentions and behaviour in that domain[ Below we describe the theories of reasoned action and planned behaviour and consider the su.ciency of these models in accounting for the translation of intentions into action[ We then de_ne self!schemas and review _ndings concerning the information!pro! cessing and behavioural guidance functions of this construct[ We suggest that previous research on relations between self!schemas\ intentions\ and behaviour possesses empirical\ conceptual\ and statistical di.culties[ A longitudinal study is reported which aimed to address these di.culties[ Correspondence to] Paschal Sheeran\ Department of Psychology\ University of She.eld\ She.eld S09 1TN\ UK[ E!mail] p[sheeranÝshe.eld[ac[uk
