ABSTRACT

Objective: This study applied the Delphi method to develop a non-face-to-face cognitive-motor intervention program for the prevention of dementia in healthy community-dwelling older adults. Methods: The study was performed from September to December 2021. First, from September to October 2021, a literature review was conducted by three researchers on cognitive-motor intervention program developments and Delphi surveys, after which the primary cognitive-motor intervention program was developed. The first Delphi survey was conducted from October 2021 to November 2021. The expert Delphi survey panel was divided into two groups: a professor group comprising occupational therapy professors from domestic and foreign universities; and a researcher group comprising those who had more than 5 years of occupational therapy clinical experience and students from the occupational therapy masters and doctoral programs. The intervention program was developed and then revised based on the results of the first Delphi survey. Twelve non-face-to-face cognitive-motor intervention program sessions were finally developed. The second Delphi survey was conducted on the modified intervention program to collect further opinions. Results: From the results of the first Delphi survey, the content validity ratio (CVR) values for all 61 items were above the standard value of .5, so no items were deleted. However, the second Delphi survey, which collected advice and opinions from the expert panel, modified the cognitive domain to match the task difficulty. The second Delphi survey results had CVR values for all 65 items of .7–1.0 and stability of .5 or less, which indicated that the expert panel's responses were stable. The degree of convergence was .125–.5, and the degree of agreement was .67–1.0. Conclusion: In this study, 12 cognitive-motor intervention program sessions were developed through a literature review and Delphi surveys to provide evidence-based interventions. The cognitive-motor intervention program derived from this study could provide evidence-based interventions based on task suitability, appropriate difficulty, valid matching, and appropriate cognitive paradigms and domains.
