Background:

Interpersonal trust is a key social construct.
Its impact on health and aging is an area of ongoing research.
Understanding factors contributing to successful aging is crucial.

Purpose of the Study:

To investigate the Rotter Interpersonal Trust Scale as a predictor of psychological well-being, functional health, and longevity.
To examine the relationship between trust and health outcomes in an aging population.

Main Methods:

A sample of 100 men and women aged 55-80 were assessed.
Rotter Interpersonal Trust Scale scores were used as baseline predictors.
Outcomes included self-rated health, life satisfaction, functional health, and mortality over 14 years.

Main Results:

Cross-sectionally, higher trust correlated with better self-rated health and life satisfaction.
Longitudinally, baseline trust predicted improved subsequent functional health over 8 years.
Mortality follow-up revealed higher trust was associated with longer survival (p = .03), even after controlling for baseline health.

Conclusions:

High levels of interpersonal trust demonstrate health-protective effects in older adults.
Trust is a significant factor in understanding successful aging.
The findings suggest potential benefits of interventions aimed at enhancing trust in aging populations.
