Breast and cervical cancers are screen-detectable; yet, challenges exist with ensuring uptake of mammography and Pap smear. Family, a central factor in developing knowledge to carry out health promotion behaviors, may be an asset to improving intention to screen among non-adherent women from underrepresented minority groups. We explored familial cancer; communication; and breast and cervical screening intention among non-adherent Black, Latina, and Arab women in the United States who participated in a randomized controlled trial of the Kin KeeperSM Cancer Prevention Intervention study. The intervention was a culturally-targeted breast and cervical cancer literacy tool for Black, Latina, and Arab women, consisting of two family-focused education sessions on the cancers, their screening guidelines, and risk-reducing health-related behaviors. For this secondary analysis, we assessed family cancer history, family communication, and screening intention for breast and cervical cancer in age-eligible, non-adherent participants. Descriptive statistics examined sample characteristics of the intervention and control groups. Odds ratios were estimated from logistic regression modeling to assess the intervention and sample characteristic effects on screening intention. Of the 516 participants, 123 and 98 were non-adherent to breast and cervical cancer screening, respectively. The intervention (OR = 1.95 for mammography; OR = 1.62 for Pap smear) and highly communicative (OR = 2.57 for mammography; OR = 3.68 for Pap smear) families reported greater screening intention. Family history of cancer only increased screening intention for mammography (OR = 2.25). Family-focused approaches supporting communication may increase breast and cervical cancer screening intention among non-adherent, underrepresented minority groups.
