CART model predicting inconsistent mammography practices (precontemplation + contemplation) for 230 women with positive perceptions (why women who have positive perceptions of mammography are not having mammograms). Notes: PC precontemplation + contemplation (shaded); A = action (white); Interest in checkup: low = not at all or a little bit; high = moderately, quite a bit, or extremely; Acceptance coping: low = not at all or a little bit; high = a medium amount or a lot; Active-planning coping: low = -not at all, a little bit, or a medium amount; high = a lot; Internal health locus: low = disagree strongly, moderately, or slightly, or agree slightly; high = agree moderately or strongly; Misclassification percentage = 36.1% (proportion whose true mammography practices differed from what the model would predict)
