Affective components in promoting physical activity: A randomized controlled trial of message framing

Area of Science:

• Behavioral Science
• Health Psychology
• Communication Studies

Background:

• Limited research explores affective components in physical activity message interventions.
• Understanding emotional processing and anticipated reactions is crucial for effective health promotion.

Purpose of the Study:

• To investigate how anticipated affective reactions and message framing influence attitudes, behavior, and intentions toward physical activity.
• To compare the effectiveness of different message frames (gain, non-loss, non-gain, loss) in promoting physical activity.

Main Methods:

• A sample of 250 participants received prefactual messages promoting physical activity via a research app.
• Four experimental conditions with varying outcome sensitivity frames were compared to a control group.
• The study measured affective attitude, concurrent behavior, and future intention regarding physical activity.

Main Results:

• Gain and non-gain messages significantly enhanced positive affective attitudes toward physical activity compared to the control.
• Improved affective attitude correlated with increased self-reported physical activity and future intentions.
• Gain messages were particularly persuasive for individuals with low positive anticipated affective reactions, eliciting hope.

Conclusions:

• Affective components significantly influence the effectiveness of physical activity message interventions.
• Framing messages to emphasize gains or non-gains can positively impact attitudes and subsequent behavior.
• Tailoring messages based on individuals' anticipated affective reactions may enhance persuasion and promote physical activity.
