Outline of Final Research Achievements

This study aimed to conduct development of leisure activity scale among modern Japanese elderly for prevention of cognitive decline, through a home-visit survey for 316 older individuals (70-84 years old). Cognitive function test (including Mini-Mental State Examination [MMSE], Memory Impairment Screen [MIS], and word-fluency test) as outcomes and 11-item leisure activity scale score as an independent variable were conducted in the survey.
1) Multiple regression analysis found a significant relationship between leisure activity score and all cognitive function test scores. 2) Each item in leisure activity scale except for “#11 competitive game” was significantly associated with MMSE score. 3) Chronbach’s alpha coefficient for the 11-item total score was 0.81. These results suggest the leisure activity scale among modern Japanese elderly has acceptable validity and reliability.
