["Adolescents are at high risk for unintended pregnancy. Given pediatricians' potential role in contraceptive counseling, understanding their attitudes and beliefs and counseling practices about use of long acting reversible contraceptives (LARC) [i.e., etonogestrel implant and intrauterine devices (IUDs)] is vital.", 'We interviewed primary care pediatricians (N=23) in a Midwestern city in June-August 2014. We transcribed the interviews, developed a coding schema, and analyzed these qualitative data using a priori and open coding of transcripts.', 'Few pediatricians had favorable views on adolescent IUD use and most did not include IUDs in routine contraception counseling. Pediatricians perceived IUDs to impose significant risks for adverse reproductive outcomes and to be poorly tolerated by adolescents. Poor and/or outdated knowledge influenced inaccurate beliefs and unsupportive attitudes. While some pediatricians were advocates for adolescent use of IUDs, many others had concerns that IUDs were not appropriate and not favored by adolescents. In contrast, participants viewed the etonogestrel implant more favorably and often included it in routine counseling. Some pediatricians focused on the familiar and readily available methods (injectable and oral contraceptives) or assumed patients had predetermined expectations for those methods. Time spent counseling on LARC was also perceived as a barrier. Pediatricians described how education and increased familiarity with LARC changed viewpoints.'] Do pediatricians ' attitudes and beliefs about long-acting reversible contraceptives influence counseling?
