Now a days clinicians are more keen to use the patient oriented self reported outcome instruments in their clinical practices and studies. Self reported instruments better predict functional status, represent a patient’s view and capture the full extent of disability. Specified questionnaire based on a particular disease or condition are potentially more responsive and sensitive than others. But there is no clear instruction or references about how to calculate sample size in PROMs? Can anyone help me in this regard?
I don't think that there is a PROM-specific method. Sample size requirements depend on many factors such as statistical test, expected effect size / desired power, measurement error... but not on the type of data collection tool per se.
