RationaleFavorable relationships with health care providers predict greater patient satisfaction and adherence to provider recommendations. However, the specific components of patient-provider relationships that account for these benefits have not been identified. The potential benefits of strong patient-provider relationships in pregnancy may be especially important, as care providers have frequent, intimate interactions with pregnant women that can affect their emotions and behaviors. In turn, prenatal emotions and health behaviors have potent effects on birth outcomes. ObjectiveThis study investigated whether pregnant women's relationships with their midwives predicted better self-care. Specific components of the patient-provider relationship (communication, integration, collaboration, and empowerment) were examined. We also investigated a mechanism through which these relationship components may be associated with salutary health behaviors: by alleviating women's anxiety. MethodsIn total, 139 low-risk patients of a university-affiliated midwifery practice in the northeastern United States completed well-validated measures assessing their relationship with midwives, state anxiety, and prenatal health behaviors in late pregnancy; state anxiety was also assessed in mid-pregnancy. ResultsWomen's perceptions of better communication, collaboration, and empowerment from their midwives were associated with more frequent salutary health behavior practices in late pregnancy. Controlling for mid-pregnancy anxiety, lower anxiety in late pregnancy mediated associations of communication and collaboration with health behavior practices, indicating that these associations were attributable to reductions in anxiety from mid- to late pregnancy. ConclusionResults substantiate that benefits of patient-provider relationships in pregnancy may extend beyond providing medical expertise. Some aspects of patient-provider relationships may offer direct benefits to pregnant women in promoting better health practices; other aspects of these relationships may indirectly contribute to better health practices by alleviating negative emotions. The benefits of strong midwife relationships may derive from the reassurance, comfort, and warmth these relationships offer, as well as the information and education that midwives provide to their patients.
