Does participating in a long-term cohort study impact research subjects' longevity? Experimental evidence from the Wisconsin Longitudinal Study.

ABSTRACT: There is considerable evidence that the act of participating in a survey can alter participants' attitudes, behaviors, and other outcomes in meaningful ways. Considering findings that this form of panel conditioning also impacts health behaviors and outcomes, we investigated the effect of participating in an intensive half-century-long cohort study on participants' longevity.
