Scoring questionnaires using the ‘qscorer’ package


Health-related questionnaires are used in many psychological studies and clinical trials. I know from my own experience that information about scoring procedures are often scattered among numerous sources and, thus, hard to find. Since I frequently work with questionnaires, I have decided to write qscorer, an R package with scoring procedures for health-related questionnaires.

To Do

In the near future, I will add control structures to the scoring functions in order to prevent items with out-of-range values to be scored. qscorer is a growing package. Thus, further scoring procedures will be added.
