Description:
A Simulation-Based Guide Using SAS
In A Practical Approach to Quantitative Validation of Patient-Reported Outcomes, two distinguished researchers, with 50 years of collective research experience and hundreds of publications on patient-centered research, deliver a detailed and comprehensive exposition on the critical steps required for quantitative validation of patient-reported outcomes (PROs). The book provides an incisive and instructional explanation and discussion on major aspects of psychometric validation methodology on PROs, especially relevant for medical applications sponsored by the pharmaceutical industry, where SAS is the primary software, and evaluated in regulatory and other healthcare environments.
Central topics include test-retest reliability, exploratory and confirmatory factor analyses, construct and criterion validity, responsiveness and sensitivity, interpretation of PRO scores and findings, and meaningful within-patient change and clinical important difference. The authors provide step-by-step guidance while walking readers through how to structure data prior to a PRO analysis and demonstrate how to implement analyses with simulated examples grounded in real-life scenarios.
Readers will also find:
A thorough introduction to patient-reported outcomes, including their definition, development, and psychometric validation
Comprehensive explorations of the validation workflow, including discussions of clinical trials as a data source for validation and the validation workflow for single and multi-item scales
In-depth discussions of key concepts related

Good to use every night...I do.
If you suffer from dry mouth during the night, these are the perfect solution. I had tried rinses - they don't last. Sprays - they don't last. lozenges - don't last. Other tablets, only last a few hours. I can get about 8 hours relief with these. Contrary to other reviews, you do not suck on them like a lozenge...they won't last at all if you do it that way. Read the directions. They "adhere" to your back molars...don't drink or eat after putting them in...as both will either dislodge or reduce the effectiveness. However, when I don't use these, my mouth is miserable and so dry. These provide enough moisture throughout the night. The flavors aren't too bad. I've used the mint (not may favorite because I'm not a fan of mint flavor), orange and berry. I wish they had other flavors (cinnamon, licorice), but till then, I'll use these probably forever.

Really helpful for dry mouth.
Scent Name: Berry, Size: 100 Count
These really work. I wear a CPAP and my mouth was so dry I was waking up with my tongue stuck to the roof of my mouth. They stick well so no worry of swallowing it during the night. I like the berry flavor.

I don't know what I would do without this product. I suffer from severe dry mouth from my medications and xylmelts have been a miracle for me. I buy them regularly and cannot live without them
I sleep comfortably with them in my mouth and they help beyond belief.
