PUQ-R Symptoms & Flares Scale Targeting. The upper histogram (pink blocks) represent the sample distribution for the scale total score whereas the lower histograms (blue blocks) represent the scale item threshold distribution plotted on the same linear measurement continuum. Targeting is satisfactory as the spread of sample and item threshold distributions are well matched. This is also displayed by the person mean location (0.067) which is very close to the item threshold mean location which is always set at zero
