INTRODUCTION Natural family planning (NFP) methods are effective for contraception with proper and consistent use. However, only 1% of patients at federally funded Title X family planning clinics select NFP as a contraceptive method. The goal of this study was to understand from clinicians' perspectives the barriers and facilitators to providing NFP methods. METHODS Six telephone focus groups were conducted with 29 clinicians from Title X clinics across the United States and Puerto Rico. A hermeneutic method was used to analyze data for related themes. RESULTS The overarching theme from the study was that participants had a strong desire to teach their patients how their bodies work and to empower them to learn to control fertility. Four subthemes emerged: patient misinformation and misunderstanding about fertility; provider ideas about ideal types of candidates for NFP; inconsistent patient teaching strategies; and lack of time to teach NFP methods. DISCUSSION There is a need for increased NFP training for providers and efficient NFP patient teaching strategies to meet the needs of patients with limited knowledge about fertility.
