INTRODUCTION: Trust between patients and clinicians is critical for better experiences and outcomes, yet there is no consensus on how trust is defined and measured in pregnancy care. We aimed to explore how patients define trust in clinicians; facilitators and barriers to building trust; and how trust may be eroded and rebuilt over time. METHODS: A bilingual, multicultural team led this qualitative focus group study. The semistructured discussion guide included definitions of trust based on a literature review, how trust is built, when trust is lost, external factors that influence the patient–clinician relationship, previous pregnancy experiences, and sources of trustworthy information during pregnancy. The discussions were audiorecorded and transcribed in the language in which they were held. We performed thematic content analysis on transcripts using both deductive and inductive approaches in each language. Codes were organized and synthesized according to emerging themes. The IRB approved this study. RESULTS: We held eight focus groups of Hispanic/Latine pregnant and postpartum patients; five were held in Spanish and three in English with a total of 35 participants. We identified five constructs of trust: communication, comfort, caring, competency, and accompaniment (“acompañamiento”). Facilitators of trust were warm interpersonal dynamics, continuity with clinician and care team, rapid direct communication with clinician, and language concordance. Barriers of trust were inadequate or inaccurate information, rotating clinicians, cold interpersonal dynamics, and language discordance. There were few differences between Spanish and English groups. CONCLUSION: Patient perspectives about building trust with clinicians are critical for improving the quality of patient–clinician relationships, especially when language barriers exist.
