[Persuasive communications and regular blood donation: an experimental study]

Area of Science:

• Behavioral Science
• Health Communication
• Social Psychology

Context:

• Understanding factors influencing regular blood donation is crucial for public health.
• Existing theories may not fully capture the nuances of donor behavior.
• University students represent a key demographic for recruitment.

Purpose:

• To investigate the impact of persuasive communication on behavioral intent to become a regular blood donor.
• To assess the variance in intent explained by independent variables within the Rational Action Theory and an expanded Rational Choice Theory.
• To test the applicability of the expanded Rational Choice Theory to blood donation behavior in a student sample.

Summary:

• A post-test only, double-blind study involving 405 university students randomly assigned to experimental, placebo, and control groups.
• Results indicated a lack of immediate yielding to persuasive communication, possibly due to the time interval.
• The positive persuasive strategy explained significant variance, with moral obligation having the greatest impact on donation intent.

Impact:

• The study validates the expanded Rational Choice Theory's theoretical and methodological soundness for predicting blood donation behavior.
• Identifies moral obligation as a key driver for regular blood donation intent.
• Highlights the need for further research into the temporal dynamics of persuasive communication in health behavior change.
