Evaluating the feasibility of using the TREATS tool in determining the quality of randomised trials of clinical aromatherapy

• The TREATS™ protocol effectively screens clinical aromatherapy studies. • Most of the reviewed articles published since 2024 are poor to fair quality. • The TREATS protocol can be used with other quality screening tools. The TREATS™ protocol was developed in 2023 to improve the quality of reporting of clinical aromatherapy studies. Whilst there has been an increase in the number of studies in the last twenty years, these are often poorly conducted and reported on. The TREATS™ contains 38 points giving an overall rating of the research as either poor, fair or good. The protocol has not been widely tested outside of its development. This project tested the feasibility of using of the tool on forty-three randomised controlled trials involving clinical aromatherapy published between 2024–2025. The tool was used to score each of the studies to provide a perspective of the quality of current clinical aromatherapy research. The project found that whilst the tool was easy to use once adapted for multiple studies, and provided a good starting point to evaluate quality, there are recommendations to enhance future iterations of the tool. The overall quality of published studies remains poor to fair according to the tool, with many areas for improvement required. The TREATS™ is effective as an initial screening tool to evaluate the quality of clinical aromatherapy research, however the quality of extant research remains poor to fair.
