Objective: Faith Moves Mountains assessed the effectiveness of a faith-placed lay health advisor (LHA) intervention to increase Papanicolaou (Pap) test use among middle-aged and older women in a region disproportionately affected by cervical cancer and low screening rates (regionally, only 68% screened in prior 3 years).

Method: This community-based RCT was conducted in four Appalachian Kentucky counties (December 2005–June 2008). Women aged 40–64 and overdue for screening were recruited from churches and individually randomized to treatment (n = 176) or wait-list control (n = 169). The intervention provided LHA home visits and newsletters addressing barriers to screening. Self-reported Pap test receipt was the primary outcome.

Results: Intention-to-treat analyses revealed that treatment group participants (17.6% screened) had over twice the odds of wait-list controls (11.2% screened) of reporting Pap test receipt post-intervention, OR = 2.56, 95% CI: 1.03–6.38, p = 0.04. Independent of group, recently screened participants (last Pap > 1 but < 5 years ago) had significantly higher odds of obtaining screening during the study than rarely or never screened participants (last Pap ≥ 5 years ago), OR = 2.50, 95% CI: 1.48–4.25, p = 0.001.

Conclusions: The intervention was associated with increased cervical cancer screening. The faith-placed LHA addressing barriers comprises a novel approach to reducing cervical cancer disparities among Appalachian women.
