THE TIME-INTERVAL IN THE INTENTION BEHAVIOR RELATIONSHIP - METAANALYSIS

Intention-behaviour models specify as a boundary condition that the intention-behaviour relationship should be measured over a short period of delay. However, a measure of intention that exists just prior to performance of the behaviour has limited feasibility and practical utility. Using meta-analysis, the present study explores the relationship between 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 moderators to this relationship. The average I-B correlation coefficient remains strong over a prediction interval of as long as 15 years. The I-B correlation is significantly influenced by the use of self-report measures of behaviour over time and type of behaviour; however, it is not influenced by how intention is measured.
