Abstract
These two studies extended previous research on the use of verbal instructions and support technology for helping persons with mild or moderate Alzheimer's disease perform daily activities. Study I included seven participants who were to carry out one of two previously targeted activities (i.e., either coffee preparation or table setting). Study II included four participants who were to carry out two new activities (i.e., preparation of a fruit salad and of a vegetable salad). The effects of activity engagement on mood (i.e., indices of happiness) were assessed by recording the participants’ behavior during the activity trials and parallel non-activity periods. The participants of Study I reached percentages of correct activity performance, which normally exceeded 85. Five of them also showed higher indices of happiness during the activity trials as opposed to the non-activity periods. Three of the participants of Study II reached high percentages of correct performance on both activities available. One of these participants also showed higher indices of happiness during the activity trials. The findings were discussed in relation to previous research outcomes and in terms of their practical implications for intervention programs.
