The recruitment goal of the Fortaleza Latina study is approximately 500 Latina women aged 40-74 who have had a clinic visit within the past 5 years, but no recent mammogram, from the four selected Community Health Center clinics. After providing informed consent and completing a baseline assessment, eligible women are randomly assigned to intervention or comparison group, within clinic. The individual-level intervention implements motivational interviewing (MI) in two participant encounters. MI is a direct counseling style, led by a promotora (lay health advisor), that elicits behavior change by helping participants explore and resolve ambivalence.
