The Cronbach α was .89. All the items except "appears physically uncomfortable" fit the model. There was a significant relationship between QoL and depressive symptoms ( r = .71, P = .001), pain ( r = .26, P = .01), physical function ( r = -.19, P = .03), and agitation ( r = .56, P = .001). The categories were appropriately used. Item mapping suggested a need for easier items.
