Longitudinal Associations Between Perceived Control and Health for American and Japanese Aging Adults

Area of Science:

• Cross-cultural psychology
• Gerontology
• Health psychology

Background:

• Longitudinal and reciprocal relationships between perceived control and health are established in Western populations.
• Associations between perceived control and health in non-Western populations, specifically aging adults, remain less understood.
• Cultural variations in the interplay between perceived control and health require investigation.

Purpose of the Study:

• To investigate cultural differences in the longitudinal associations between perceived control and health among American and Japanese aging adults.
• To examine whether perceived control predicts changes in health outcomes and vice versa across different cultural contexts.

Main Methods:

• Analysis of longitudinal data from Midlife in the United States (N=4,455) and Midlife in Japan (N=827) surveys.
• Cross-lagged path models were used to assess perceived control predicting health changes and health predicting perceived control changes.
• Participants were aged 40 and older at Time 1 (T1) and followed up at Time 2 (T2).

Main Results:

• Perceived control at T1 predicted changes in chronic health conditions only for American adults.
• Similar tendencies were observed for perceived control predicting self-rated health and functional limitations across nationalities.
• Reciprocal relationships between perceived control and health were evident in Americans, but not in Japanese respondents.

Conclusions:

• Significant cultural differences exist in the relationship between perceived control and health among aging adults in the US and Japan.
• Findings suggest potential health benefits of enhancing perceived control, with culturally tailored interventions being important.
• Further research is needed to explore these cross-cultural dynamics in greater depth.
