Identity-based motivation and health.

People do not always take action to promote health, engaging instead in unhealthy habits and reporting fatalism about health. One important mechanism underlying these patterns involves identity-based motivation (D. Oyserman, 2007), the process by which content of social identities influences beliefs about in-group goals and strategies. Seven studies show the effect of identity-based motivation on health. Racial-ethnic minority participants view health promotion behaviors as White middle class and unhealthy behaviors as in-group defining (Studies 1 and 2). Priming race-ethnicity (and low socioeconomic status) increases health fatalism and reduces access to health knowledge (Studies 3 and 4). Perceived efficacy of health-promoting activities is undermined when racial-ethnic minority participants who identify unhealthy behavior as in-group defining are asked to consider their similarities to (middle-class) Whites (Studies 5-7).
