The present study examines worry themes and the tendency to worry in older adults. The sample, which is made up of 162 participants, is divided into three groups. The first group includes 47 participants aged from 55 to 64 years old (the youngest subjects). The second group consists of 56 participants aged from 65 to 74 years old. Finally, the third group includes 59 participants who are 75 years old or older (the oldest subjects). Participants completed the Worry and Anxiety Questionnaire, the Worry Domains Questionnaire for Older Adults and the Penn State Worry Questionnaire. For all subjects combined, the most frequently reported worry theme was health, followed by relationships with family and friends. The results show that participants in group 1 (the youngest subjects) worry more about their future, work and finances than those in the other two groups. The results also show that participants in the first two groups have a greater tendency to worry and report a greater number of worries than those in the third group (the oldest subjects). The study's findings are discussed in light of current knowledge of worry among the elderly.
