Hypothesis
This study compares the aging trajectory between the JST-IC and TMIG-IC among community-dwelling older Japanese individuals.
Conclusion
The JST-IC score gradually declined with age across all patterns, linked to declines in technology usage, life management, and social engagement.
Supporting Evidence
- The JST-IC was developed to measure higher levels of competence than the TMIG-IC.
- Three patterns of aging trajectories were identified for both JST-IC and TMIG-IC.
- Scores for technology usage, life management, and social engagement declined with age.
Takeaway
As people get older, their ability to use technology and manage their lives tends to go down, according to a study of older adults in Japan.
Methodology
The study used group-based trajectory modeling to identify aging patterns in JST-IC and TMIG-IC scores.
Participant Demographics
Community-dwelling older Japanese individuals.
