Distant healing of surgical wounds: an exploratory study

Area of Science:

• Complementary and Alternative Medicine (CAM)
• Psychoneuroimmunology
• Integrative Oncology

Background:

• Distant healing intention (DHI) is a common CAM modality with inconsistent clinical trial results.
• Potential confounding factors like expectation and belief may explain DHI efficacy ambiguity.
• Investigating these psychosocial variables is crucial for understanding DHI's role.

Purpose of the Study:

• To investigate the influence of expectation and belief on DHI's effects.
• To examine DHI's impact on objective (collagen deposition) and psychosocial measures in women undergoing surgery.
• To explore the relationship between participant/healer factors and DHI outcomes.

Main Methods:

• 72 women undergoing plastic surgery were randomized into three groups: blinded DHI, blinded control, and expectancy (aware of DHI).
• Objective measures included collagen deposition in a surrogate wound.
• Psychosocial outcomes were assessed via self-report measures.
• DHI was administered by experienced distant healers.

Main Results:

• No significant differences in main outcome measures were found across the three groups.
• Participant belief in DHI correlated negatively with mental health status post-study.
• Healer's perceived contact quality correlated negatively with mood change and collagen deposition.
• Post-hoc analysis: blinded DHI recipients undergoing reconstructive surgery showed improved mood compared to elective cosmetic surgery patients.

Conclusions:

• Ambiguity in DHI studies may stem from interactions between participant/healer beliefs, expectations, and motivations.
• Psychosocial factors significantly influence DHI outcomes, warranting further investigation.
• Future research should consider these complex interactions to clarify DHI's efficacy.
