This study aimed to systematically identify these barriers and facilitators, map them with Theoretical Domains Framework (TDF) and Behavior Change Techniques (BCTs) to inform the development of interventions promoting pregnant women's involvement in clinical research.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a mixed\u2010methods systematic review. PubMed, Embase, Cochrane Library, APA PsycInfo, CINAHL, China National Knowledge Infrastructure, WanFang, VIP Database for Chinese Technical Periodicals, Chinese Biomedical Literature Database, and related references were searched. Qualitative, quantitative, and mixed\u2010methods studies exploring barriers and facilitators to pregnant women's participation in clinical trials were included. The barriers and facilitators were extracted, after transforming the quantitative data into qualitative data, all qualitative data were used to thematic synthesis.
