Perceived Life Expectancy Predicts Time Investment in Productive Aging Activities: An Ecological Momentary Assessment Study.

Objectives: Despite known benefits of productive aging, it is unclear what explains time allocation in productive activities. We investigated whether productive engagement in older people can be explained by their age, health, socioeconomic status, and perceived life expectancy in Hong Kong.

Methods: We interviewed 390 community-dwelling older persons for their health and perceived life expectancy, followed by a 7-day ecological momentary assessment to record their activities.
