- Groups received basic vs. enhanced information about the placebo program.
Main Results:
- Warm communication led to significantly higher expectations of treatment effects.
- Participants in the warm condition reported greater subjective improvement.
- No significant differences were found based on information type or actual performance.
Conclusions:
- Nonverbal communication, including facial expression and tone, is crucial for enhancing expectations and subjective improvement.
- Provider warmth, not information quantity, strengthens placebo effects.
- Focusing on empathetic communication can improve patient-reported outcomes.

Sharing information, concepts, and emotions to foster mutual understanding is communication. The sender, recipient, and transaction must be considered in this manner. The sender is the person who shares the message, the recipient is the person who receives and understands the message, and the transaction is the method used to deliver the message and the variables that affect the communication's context and surroundings.
