Interpreting the NUMi CAT

The NUMi CAT was developed using item response theory.  Scores indicate the level of ability and theoretically can range from -3.0 to 3.0. The following categories have been determined to facilitate interpretation of these scores and are based upon the distribution of scores in our validation sample.  Clinician reports designed to explain how these scores correlate with risk communication skills are available below.

Low health numeracy level, -3.0 to -0.452
Medium health numeracy level, -0.451 to 0.519
High health numeracy level, 0.520 to 3.0
