ManagingLife is a company that supports a web-based app, called Manage My Pain, that is used to helpindividuals with chronic pain record their pain experiences. In an NSERC Engage project with the company,we have developed a statistical framework (using key record characteristics) to statistically define userengagement with the app. Our analysis identified five groups (or clusters) of user engagement and our work hasbeen used to support a collaborative effort in pain research. The current project extends our statisticalframework to a more in-depth study of the longitudinal data that will be used to statistically define significantincreases or decreases in pain index data. The analysis will include methods that allow for imputation ofmissing data, and comparisons of longitudinal data sets that have vary by app use longevity, number of records,and frequency of use. ManagingLife will use the analytical framework to aid patients in understanding theirpain experience.
