We studied the impact of the diagnostic label of osteoarthritis and educational information on family members' attributions, perceptions, and willingness to help older parents with pain. Undergraduate students (N = 636) were randomly assigned to one of three conditions where they read vignettes about an older mother with chronic pain, which varied on illness label and educational information. Results indicated that both the osteoarthritis label and osteoarthritis information led to more positive perceptions compared with no label/healthy aging information. Results highlight the importance of diagnosis and education in promoting favorable attributions and increasing willingness to help older adults with osteoarthritis. (Contains 1 table and 4 figures.)
