Background: Conventional wisdom assumes a one-dose intervention might facilitate one-time adherence and booster doses might facilitate maintenance. This study tested effects of a booster intervention on mammography adherence.

Methods: The 1245 participants, at least 51 years old and non-adherent at baseline, were from a university-affiliated clinic (83% African American) and an HMO (76% Caucasian). Each was assigned to usual care, tailored print, tailored phone counseling, or both print and phone. One year later, intervention recipients were randomly assigned to receive a booster or no booster dose of their original intervention. We used logistic regression to test effects on adherence at 6 and 15-months post booster.

Findings: Among the 44% screened following initial intervention, booster recipients were more likely to be re-screened by 6 months post booster (OR=1.68; p=.038) but the effect was no longer significant by 15 months (OR=1.15; p=.54). Among the 56% not screened after initial intervention, the booster had no significant effect on adherence at either 6 or 15 months.

Conclusion: We expected more re-screening among booster recipients and that the booster dose might facilitate first mammograms among women not screened after initial intervention. Instead, findings suggest: (1) booster interventions may facilitate timely re-screening but, eventually, adherence in booster/no booster groups will be similar, and (2) a booster dose will not be effective if the first intervention dose is not.

Learning Objectives:

• A. Participants will understand the effectiveness of booster intervention doses for promoting second mammograms among women screened after first intervention dose.
• B. Participants will understand the effectiveness of booster intervention doses for promoting first-time screening among women not screened after first intervention dose.
