ADCS Prevention Instrument Project: Pilot Testing of a Book Club as a Psychosocial Intervention and Recruitment and Retention Strategy.

摘要

Both psychosocial and biologic interventions may delay or prevent Alzheimer disease. Staying mentally active may help older people maintain their cognitive abilities. In the Alzheimer Disease Cooperative Study Prevention Instrument Project a book club was introduced as a recruitment and retention device. A 3-arm study was designed and included: a nonrandomized, self-selected group (n=211) who chose not to participate in the book club, and 2 groups randomly assigned to receive 2 books per year in individual self-improvement (n=210) or community involvement (n=207) categories. Participants reported their reactions to the selections and other reading behaviors. Results from the first 2 years revealed that most book club participants agreed with Likert-type statements indicating the readings were enjoyable (P<0.001), had an impact on their thinking (P=0.01), and were shared by them with others (P=0.002). Respondents in the community involvement group agreed more strongly with these statements than those inthe self-improvement category. Comments from participants in response to open-ended questions in the reader survey revealed such themes as developing plans for successful aging and reflecting on attitudes and behaviors in their own lives. Further longitudinal analyses are planned to determine whether the book club influenced retention and whether participation was associated with slowing cognitive decline.
