This study tests the hypotheses that (a) severity of arthritis is inve
rsely associated with frequency of activity participation, and (b) art
hritis sufferers who maintain higher levels of participation, particul
arly in activities which are social in nature, are less likely to expe
rience a decline in well-being. Three activity types are considered: s
ocial, physical, and solitary. Results indicate that well-being is inf
luenced by social activity, whereas solitary and physical activity hav
e minimal impact. This suggests that elders with arthritis need not re
move themselves from the pursuit of activity and should be encouraged
to develop new interests when physical functioning fails. The study al
so demonstrates the utility of considering activity as multidimensiona
l.
