Temporal distance and blood donation intention.

This study tested Construal Level Theory and examined social desirability and cultural differences as factors affecting blood donation intention across different time frames. Findings showed that individuals indicated stronger intentions for the distant future (one-year and no-time indication frames) than for the near future (one-week and three-month frames). The relationship between social desirability rating of blood donation and intention was positive and significant for the no-time indication frame, but it was not significant for the one-week time frame and the three-month time frame. Koreans and Americans did not differ in the relationship between social desirability and intentions across different time frames.
