Study Design & Methodology
Research Approach
- Type: Qualitative Convergent Care Research (CCR)
- Theoretical Framework: Michel Maffesoli’s Comprehensive and Everyday Sociology
- Focus: Understanding the imagery (shared meanings) of Reiki in daily lives of cancer patients and families
Participants
- 20 total participants: 15 undergoing chemotherapy, 5 family members
- 15 women, ages 26-75 years
- Various cancer diagnoses: multiple myeloma (5), breast cancer (3), bowel, pancreatic, leukemia, lymphoma, bladder, and cervical cancers
- Treatment duration: 3 months to 9 years
- Occupations: business owners, hairdresser, plumber, student, manager, nursing technician, housewives, retired persons
Reiki Intervention
- Administered by nurse researcher (primary author, qualified Reiki practitioner)
- 3-5 sessions per participant, 20-30 minutes each
- Separate from chemotherapy infusion times
- Hands placed on areas of pain and following traditional Reiki positions (face, chest, abdomen, dorsal region)
- Sessions in medical offices with low/no lighting for optimal reception
Data Collection
- Individual open interviews after each Reiki session
- Semi-structured interview guide
- Interviews lasted 20-30 minutes
- Audio recorded and fully transcribed
- Questions explored: experience of cancer, meanings of Reiki practice, changes noticed
Analysis Method
- Thematic Analysis following Operative Proposal
- Three stages: pre-analysis, material exploration, interpretation of results
- Data saturation determined completion of data collection
- Nursing Care Process framework integrating Daily Life and Imaginary in Health
Ethics
- Approved by Research Ethics Committee (Opinion #2,765,976)
- All participants signed Informed Consent Form
- Participants chose code names for anonymity
Key Themes Emerged
The Reiki Experience
- Feeling Good: Participants described improvements in throat problems, leg pain, and chemotherapy symptoms
- General Well-being: Physical, mental, and spiritual aspects improved, strengthening quality of life
- Break in Routine: Reiki provided a pause in disease-focused daily life, a moment of self-care
- Enhanced Daily Function: Better sleep, work capacity, more willingness, reduced sensations of pain
Meanings of Reiki
- Emotional Tranquility: Helped make difficult decisions (like hair loss) with greater calm
- Energy Balance: Natural improvement through vital energy transfer
- Spiritual Connection: Involved psychological and spiritual aspects, fascinated participants
- Inner Strength (Potency): Awakened vital force to win each day, feel light and strong to fight disease
- Demystification: Changed focus from disease to positive attitude, illuminating inner power
Study Strengths
Rich Qualitative Data: Captured deep personal experiences and meanings that quantitative methods cannot reveal
Family-Centered Approach: Rare inclusion of family members’ perspectives in Reiki research
Theoretical Depth: Grounded in established sociological theory (Maffesoli’s work on imaginary and everyday life)
Integration with Nursing: Demonstrates how Reiki fits within professional nursing care processes
Real-world Setting: Conducted during active cancer treatment, showing practical applicability
Comprehensive Benefits: Documented physical, emotional, spiritual, and social impacts
Participant Voices: Direct quotes preserve authentic experiences and meanings
Ethical Rigor: Proper consent, anonymity, and ethics approval
Limitations
Small Sample Size: 20 participants limits generalizability (though appropriate for qualitative research)
Single Site: Conducted at one clinic in southern Brazil
No Control Group: All participants received Reiki; no comparison with standard care alone
Single Practitioner: All Reiki administered by one nurse researcher
No Long-term Follow-up: Effects tracked only during treatment period
Variable Session Numbers: Participants received 3-5 sessions (not standardized)
Self-reported Only: No objective physiological measurements
Real-World Impact & Significance
For Healthcare: Demonstrates how complementary practices like Reiki can be integrated into conventional cancer care through nursing, addressing gaps in holistic patient support.
For Patients: Shows that Reiki offers more than symptom relief—it can help patients reclaim their sense of self, find inner strength, and shift from feeling like victims of disease to active participants in their healing.
For Families: Validates the benefit of including families in complementary care, recognizing that cancer affects entire family systems.
For Policy: Supports Brazil’s National Policy on Integrative and Complementary Health Practices (PNPICS), which integrated Reiki into public health services in 2017.
What This Study Adds to Reiki Research
- Explores the meanings and imagery of Reiki from patients’ and families’ perspectives
- Shows how Reiki fits within professional nursing care frameworks
- Documents the “imaginary” (shared cultural meanings) that emerges from Reiki practice
- Demonstrates feasibility in real cancer treatment settings
- Addresses the often-overlooked family dimension of cancer care
- Provides theoretical grounding in sociology for understanding Reiki’s effects
- Captures existential and spiritual dimensions of healing beyond symptom reduction
Future Research Needs
- Mixed-methods studies combining qualitative depth with quantitative outcome measures
- Larger sample sizes across multiple sites and cultural contexts
- Controlled trials to isolate Reiki’s specific effects from attention and therapeutic relationship
- Long-term follow-up to assess durability of psychological and spiritual changes
- Investigation of optimal session frequency, duration, and total number
- Studies examining which patient characteristics predict best response
- Research on family member outcomes and family system effects
- Cost-effectiveness analysis for healthcare system integration
- Exploration of mechanisms by which Reiki influences the “imaginary” and promotes healing
