Motivational Interviewing (MI) reduces threats in environmental behavior change conversations. This approach enhances intrinsic motivation by lowering social and cognitive threats, supporting sustainable practices.
Area of Science:
- Environmental Psychology
- Behavioral Science
- Communication Studies
Background:
- Human behavior significantly impacts environmental resource waste.
- Feedback on environmental behavior can be perceived as threatening, reducing intrinsic motivation for change.
- Self-determination theory (SDT) and self-affirmation theory (SAT) explain how threats impact motivation and self-integrity.
Purpose of the Study:
- To examine recipient responses to threats in environmental behavior change interactions.
- To investigate how Motivational Interviewing (MI) mitigates social and cognitive threats.
- To understand the role of MI in fostering intrinsic motivation for pro-environmental behavior.
Main Methods:
- 68 dyadic interactions between change agents and recipients were videotaped.
- Change agents either used MI or were in a control group.
- Verbal threats, expressions of motivation, perceived confrontation, and empathy were coded and rated.
Main Results:
- MI significantly reduced threats from change agents.
- Perceived confrontation aligned with observable agent behavior.
- Threats negatively correlated with recipients' expressed motivation to change.
- No significant relationship was found between agent threats and recipient "sustain talk" (self-defenses).
Conclusions:
- MI effectively reduces threats in environmental behavior change discussions.
- MI lessens adverse social and cognitive impacts, supporting intrinsic motivation.
- Findings offer practical insights for environmental change agents using MI techniques.
