Does the mYPAS-SF retain the accuracy of the original mYPAS?
The mYPAS-SF is a valid, shorter alternative to the mYPAS for measuring preoperative anxiety, facilitating easier use in clinical research.
Reducing the mYPAS to 4 items, creating the mYPAS-SF that can be administered at 2 time points, retained the accuracy of the measure while allowing the instrument to be more easily used in clinical research settings.
Jenkins et al. (Thu,) studied this question.
