Lay theories of health, self-rated health, and health behavior intentions

Abstract

We used an experimental design to examine young adults’ ( N = 247; M age = 19.71; 86% female) intentions to engage in health-promoting behaviors in relation to beliefs concerning whether health is malleable or fixed, and how their health is unfolding over time. Individuals in the incremental (health is malleable) and control conditions viewed their health as improving over time; those in the entity (health is fixed) condition viewed their health as relatively stable. Individuals with more incremental theories of health and those who viewed their health as improving over time (particularly past to present) reported stronger health-promoting behavior intentions.
