This study examined whether the factors influencing a woman's intention to get a mammogram differ between women who have had mammograms in the past (prior screenees) and those who have not (nonscreenees). Responses to a survey were used to predict mammography intentions separately for two groups of women: those with no previous mammograms and those with one. Among the prior nonscreenees, the variables we examined accounted for nearly half the variance in intentions; among the prior screenees, only one‐sixth of the variance was accounted for. This suggests that interventions that succeed in increasing mammography utilization among prior nonscreenees may not necessarily be successful among prior screenee
