Ecological Validity of PROMIS Instruments

This is a 4-week longitudinal (repeated measures) protocol with 5 separate samples:(1) a general community sample, (2) a sample of patients with osteoarthritis, (3) a sample of women reporting premenstrual symptoms (PMS/PMDD), (4) a sample of men undergoing hernia surgery, (5) a sample of women with breast cancer undergoing chemotherapy. In each sample, participants completed PROMIS CATs for 3 selected PRO domains at the end of each week, and completed end-of-day diary PROs for corresponding domains on each day of the 4-week period. PRO domains assessed vary by sample. For each sample, the data are stored in 3 datasets: [a] participant characteristics (1 row per participant); [b] weekly PROMIS CAT data (in a "stacked" file, up to 4 rows per participant); [c] daily diary data (in a "stacked" file, up to 28 rows per participant). Datasets for each sample can be merged using the variables ID and DAY (for stacked files) as identifiers.
