Reducing Psychological Reactance to Health Promotion Messages: Comparing Preemptive and Postscript Mitigation...

Area of Science:

• Health Communication
• Social Psychology
• Behavioral Science

Background:

• Psychological reactance can undermine health campaign effectiveness.
• Autonomy-supportive messages may mitigate reactance.
• Understanding effective reactance-mitigation strategies is crucial for public health.

Purpose of the Study:

• To compare the efficacy of preemptive scripts and restoration postscripts in mitigating psychological reactance.
• To examine the impact of these strategies on attitude and behavioral intention.
• To assess the long-term effects of these strategies on health campaign outcomes.

Main Methods:

• A mixed-model experiment with 394 participants was conducted.
• A 2x3x2 between-subjects design included threat to freedom, reactance-mitigation strategy (control, preemptive script, restoration postscript), and health campaign topic (exercise, nutrition).
• A within-subjects factor of time (immediate and one-week delay) measured reactance, attitude, and behavioral intention.

Main Results:

• Both preemptive scripts and restoration postscripts significantly reduced psychological reactance compared to the control.
• The reactance-mitigation strategies had equivalent effects on reducing reactance.
• Reduced reactance indirectly led to improved behavioral intention through attitude change, persisting after one week.

Conclusions:

• Autonomy-supportive strategies, like preemptive scripts and restoration postscripts, are effective in mitigating psychological reactance in health campaigns.
• These strategies enhance message effectiveness by fostering positive attitude change and behavioral intention.
• The positive effects on behavioral intention are sustained over time, highlighting the practical utility of these approaches.
