Physical Activity Promotion Message Perceptions Biased by Motivational Dispositions

Area of Science:

• Health Psychology
• Behavioral Science
• Communication Studies

Background:

• Physical activity (PA) promotion is key to interventions.
• Gain-framed messages show inconsistent benefits for PA behaviors.
• Motivational traits' role in message perception is understudied.

Purpose of the Study:

• To investigate if motivational traits moderate perceptions of PA messages.
• To test the interaction between message framing and individual motivational traits.

Main Methods:

• Developed 15 PA statements across five conditions (frame, kernel state).
• 800 participants rated statements on semantic differential scales.
• Measured motivational traits and PA levels via surveys.

Main Results:

• Gain-framed statements positively correlated with approach motivation.
• Loss-framed statements negatively correlated with avoidance motivation.
• Evidence of a congruency effect between traits and message frame.

Conclusions:

• Motivational traits and message frame congruency influence message perception.
• Future research should examine effects on persuasion and intervention effectiveness.
