Dm. Randall et Ja. Wolff, THE TIME-INTERVAL IN THE INTENTION BEHAVIOR RELATIONSHIP - METAANALYSIS, British journal of social psychology, 33, 1994, pp. 405-418
Intention-behaviour models specify as a boundary condition that the in
tention-behaviour relationship should be measured over a short period
of delay. However, a measure of intention that exists just prior to pe
rformance of the behaviour has limited feasibility and practical utili
ty. Using meta-analysis, the present study explores the relationship b
etween time and the intention-behaviour <I-B> correlation in Fishbein
and Ajzen's intention-behaviour models. Self-reported behaviours, how
intention is measured, and type of behaviour are explored as moderator
s to this relationship. The average I-B correlation coefficient remain
s strong over a prediction interval of as long as 15 years. The I-B co
rrelation is significantly influenced by the use of self-report measur
es of behaviour over time and type of behaviour; however, it is not in
fluenced by how intention is measured.
