PUQ-R Scale Threshold map Examples. Threshold maps for all PUQ-R scales. The x-axis represents the measurement continuum of the trait (uncertainty), with decreasing levels from left to right. The y-axis shows each of the items response categories “Very Uncertain” labeled as 0; “Somewhat Uncertain” labeled as 1; “Somewhat Certain” labeled as 2 and “Very Certain” labeled as 3. Thresholds for items are missing and replaced with ** if they are disordered, i.e. response categories do not appear in a consecutive increasing order in relation to the construct (x-axis)
