Abstract
OBJECTIVE: The evaluation of the effect of a mammography decision aid (DA) designed for older women at risk for lower health literacy (LHL) on their knowledge of mammography's benefits and harms and decisional conflict.
METHODS: Using a pretest-posttest design, women > 75 years at risk for LHL reviewing a mammography DA before and after their [B] primary care provider visit. Women were recruited from an academic medical center and community health centers and clinics.
RESULTS: Of 147 eligible women approached, 43 participated. Receipt of the DA significantly affected knowledge of mammography's benefits and harms [B] (pre-test (M = 3.75, SD = 1.05) to post-test (M = 4.42, SD = 1.19), p = .03). Receipt of the DA did not significantly affect decisional conflict (pre-test (M = 3.10, SD = .97) to post-test (M = 3.23, SD = 1.02), p = .71, higher scores = lower decisional conflict). The majority of the women (97%) indicated that the DA was helpful.
CONCLUSIONS: Women found a mammography screening DA helpful and its use was associated with these women having increased knowledge of mammography's benefits and harms.
PRACTICE IMPLICATIONS: With the shift toward shared decision-making for women > 75 years, there is a need to engage women of all literacy levels to participate in these decisions and have tools such as the one tested in this study.
