Brief summary

The aim of this project is to assess the psychometric properties of a ‘point of collection’ technology to measure salivary cortisol levels in adults. Objectives are to use the IPRO© ‘point of collection’ saliva analysis method to report: 1) concurrent validity by comparison with reference standard cortisol assay analysis; 2) over-time reliability of cortisol measurements; 3) inter-rater reliability of cortisol measurements.

Interventions

This is a prospective observational cross-sectional, study, designed to assess concurrent validity and reliability of the IPRO© method point of collection salivary cortisol measurement method. This project will be conducted in the physiotherapy practical examination rooms of the exercise and rehabilitation sciences building (43), and the biomedical science laboratories at JCU Bebegu Yumba campus in Townsville, Queensland.

This is a prospective observational cross-sectional, study, designed to assess concurrent validity and reliability of the IPRO© method point of collection salivary cortisol measurement method. This project will be conducted in the physiotherapy practical examination rooms of the exercise and rehabilitation sciences building (43), and the biomedical science laboratories at JCU Bebegu Yumba campus in Townsville, Queensland. All participants will be healthy adults and will provide a sample of saliva whilst sitting in a rested state. Participants will have provided informed written consent prior to saliva sampling. The whole sampling process will take a maximum of 30 minutes. Participants will place three swabs into their mouth until they are soaked in saliva, They will then spit the swabs into three sterile vials. Once the saliva samples have been provided participants involvement in the study is complete. Analysis of the saliva samples will be conducted independently of the participants.
