Vested interest, disaster preparedness, and strategic campaign message design

Area of Science:

• Social Psychology
• Public Health Communication
• Emergency Management

Background:

• Limited success of traditional campaign-based disaster preparedness programs in the US.
• Americans are generally uninformed and unprepared for disasters.
• Need for innovative strategies to enhance individual-level disaster preparedness.

Purpose of the Study:

• To test the effectiveness of television-based disaster preparedness messages using Vested Interest Theory.
• To compare high- and low-vested message versions on behavioral intentions, message acceptance, and preparedness attitudes.
• To identify message design elements that improve disaster preparedness outcomes.

Main Methods:

• Utilized Vested Interest Theory (Crano, 1997) as a theoretical framework.
• Developed and compared high- and low-vested versions of a disaster preparedness public service announcement (PSA).
• Assessed message efficacy through behavioral intentions, message acceptance, and preparedness attitudes.

Main Results:

• Television-based PSAs with subtle message variations can influence preparedness attitudes.
• The high-vested message condition significantly outperformed low-vested and control conditions.
• High-vested messages improved behavioral intentions and self-efficacy perceptions.

Conclusions:

• Tailoring disaster preparedness messages to increase personal vested interest enhances effectiveness.
• Subtle message variations in PSAs can significantly impact public preparedness.
• Vested Interest Theory provides a valuable framework for designing impactful disaster communication strategies.
