Health mindsets can be viewed on a continuum of malleability from fixed (health cannot be altered) to growth (health can be affected by behavior). We propose that mindsets may influence the health perceptions of healthy adolescents as well as the health behaviors of adolescents with a chronic illness. In Study 1, we surveyed healthy adolescents about their health mindsets and their judgments of illness in response to vignettes of fictional others. In Study 2, we measured the health mindsets and health behaviors of adolescents with type 1 diabetes In Study 1, healthy adolescents with a fixed health mindset were more likely to rate fictional others as being less healthy, less likely to recover, and more vulnerable to additional diseases. In Study 2, a growth mindset was associated with a greater frequency of glucose monitoring among younger, but not older, adolescents with type 1 diabetes. Further, growth mindset was associated with lower HbA1c levels for younger adolescents. Health mindsets may shape views of the implications of illness or injury for overall health and, in adolescents with a chronic condition, may interact with age to influence health behaviors and outcomes.
