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

My dog loves the Multipet Skele toys!
Size: 15", Style: Duck
My dog absolutely loves this toy and the similar ones (we had a snowman first). He rolls around with it and seems to be so happy. My dog is an aggressive chewer- and he destroys these toys within a couple of months. We have to take pieces of it away as they come loose, especially the squeeker, but he still plays with the rest. I wish it would last longer because he really loves it, but I haven’t found a toy that he cant destroy yet.

Terrible!!!!
Size: 15", Style: Duck
My 2 Australian shepards destroyed this cheaply made toy in 20 minutes! It's advertised for tough chewers, lol, the material it was made from is so thin, you could almost see through it. Don't waste your time or money!

My dogs love it
Size: 15", Style: Rabbit
I have to say, this is not an indestructible toy. It would have been better made without the squeaker or filling in the head. Once I removed those (after the dogs dug them out) they have played with this and the chicken (by the same company) for months. It's looking a bit ragged and I had to eventually cut the face off since they had chewed into it. However, the ropes have held despite multiple games of tug-of-war. My rat terrier and Moxie mix love these toys. Best ones we've found to last.

Quality Toy
Size: 15", Style: Duck
Fun durable toy for tough chewers. Material is durable and long lasting, however can unravel with extended chewing or pulling. A favorite of our dogs. Easy to throw and toss in a game of fetch.

My grand furbaby loves this yellow duck!
Size: 15", Style: Duck
I bought this yellow duck as a gift for my grand furbaby about 2 years ago. It turned out to be his favorite toy and it lasted for quite some time. So, I have bought several of them and when I go to stay with him in the summer, I take him a brand new yellow duck. He carries it around with him and he loves it! Favorite toy!
