10.55. EuroQol 5-Dimension, 5-Level Health Scale (EQ-5D-5L)¶
(¶+) Reproduction of this task/scale is not permitted (or such permission is not clear). This CamCOPS task is a data collection tool only, with no scale text (unless configured locally to use externally provided text that the hosting institution is legally permitted to use). Use it only in conjunction with a licensed copy of the original task. If your institution is entitled to use the task, you may install an add-on XML file on your server containing the required strings, to make the task fully functional, but you must provide this XML file and its contents yourself (it is outside the scope of CamCOPS).
A descriptive system comprising five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The second task component is a visual scale wherein the patient is asked to rate their health on a scale of 0 to 100.
EQ-5D-5L evolved from EQ-5D-3L, as the five level classifier provided greater discriminative ability and more power to detect differences between groups.
