Note. Items in boldfacewere selected for the Military Health Care Frustration – Self 6-item short form
Underlined items were selected for the Military Health Care Frustration – Person with TBI 6-item short form. Slopes are the discrimination parameters (which are held constant in a Rasch model). Thresholds are the location (or difficulty parameters); they indicate the locations on the measurement continuum where an item can provide its most precise measurement. Thus, items with lower value thresholds measure most precisely at those lower score values (the item can therefore be thought of as an easier item). Items with higher threshold values measure most precisely at those higher score values (the item can therefore be thought of as a harder item).
