Four items describing basic activities (whether can feed yourself, dress, get in and out of bed, and take a bath) each of which has three possible values (1=without help, 2=some help, 3=completely unable) are summed. A lower score indicates greater ability to cope with daily living activities. Missing if any of the four items are missing.

Starting in Ext1, two additional activity questions have been added (Form 160, questions 23-24). This allows for a similar calculation of a 6-item ADL construct.
