The present study, carried out on 270 women and men, uses the
model of the theory of planned behavior (Ajzen, 1985), to predict the
change of political party. The latter is actually predicted by attitude,
subjective norms and behavioral intention. On the other hand, perceived
control does not seem to have any statistically observable role.
Membership in a political party follows the same rules as other types of
groups, namely identification, utility and cohesion. The negative
representation of the change of party would be due to external attributions
not taking into account individual realities and sometimes having a
monetary character.
