The Delphi Study Updates
To address the need for a globally endorsed reporting standard in aromatherapy research, ARQAT conducted a Delphi consensus study involving international English-speaking researchers, academics, and clinicians. The study aimed to establish a minimal reporting guideline to ensure research is comprehensible, reproducible, clinically interpretable, and suitable for systematic reviews. Participants engaged in four online electronic survey rounds, providing qualitative and quantitative feedback to refine the guidelines. The protocol for this study can be found at https://journals-plos-org.wvu.idm.oclc.org/plosone/article/metrics?id=10.1371/journal.pone.0318379#viewedHeader
The study utilized a modified Delphi methodology, incorporating a hybrid introductory meeting and asynchronous online surveys to accommodate global participation. Participants rated items on a 5-point Likert scale, with consensus criteria set for inclusion or exclusion based on predefined thresholds. Items were re-evaluated across rounds until consensus was achieved or
termination criteria were met. Qualitative feedback was also analyzed to identify patterns and themes, with relevant suggestions incorporated into subsequent rounds.
Data analysis was conducted using Excel, with responses anonymized and shared with participants after each round. The study adhered to strict data protection protocols, ensuring secure storage and retention of research data. The finalized guidelines aim to enhance the quality and consistency of aromatherapy research worldwide, supporting its integration into clinical practice and systematic reviews.
The study closed in May 2025, and data analysis is complete. The student pilot was successful, and the manuscript is being prepared. For more information, please contact us at info@arqat.org. Thank you.
