This study developed the RTSS-Voice, a standardized system for categorizing voice therapy treatments. This system helps identify specific treatment components responsible for patient improvements in voice therapy research and practice.
Area of Science:
- Speech and Hearing Sciences
- Rehabilitation Medicine
Background:
- Standardized voice treatments show efficacy, but specific effective components remain unclear.
- Identifying unique treatment elements is crucial for advancing voice therapy.
Purpose of the Study:
- To develop the RTSS-Voice, a consensus-based taxonomy of measurable and unique voice treatment ingredients and targets.
- To address the elusiveness of identifying specific effective components in voice therapy.
Main Methods:
- Utilized the Rehabilitation Treatment Specification System (RTSS) and a six-round Delphi process with 10 experts.
- Experts rated measurability and uniqueness of voice treatment targets and ingredients.
- Consensus was achieved through a supramajority threshold (≥ 8/10 agreement).
Main Results:
- Achieved consensus on 35 measurable and unique target categories and 19 ingredient categories for RTSS-Voice.
- Developed operational definitions detailing ingredient delivery and target modification.
- Established a standardized framework reflecting voice therapy terminology.
Conclusions:
- RTSS-Voice offers potential to enhance voice therapy research, clinical practice, and education.
- The methodology may be applicable to developing specifications for other speech and hearing treatments.
