Psychosocial risk factors for preterm delivery have been a topic of much recent research. By extension, the role of psychosocial risks in the explanation of the racial and ethnic gap in preterm birth is of increasing interest. Several barriers that are related to the measurement of psychosocial variables may preclude a sound understanding of their role in the explanation of the racial gap in preterm birth. The purpose of this study was to present selected principles of measurement that should be addressed during the investigation of the relationship between psychosocial factors and preterm delivery to gain a greater understanding of the racial gap in preterm birth.
早产的心理社会风险因素一直是近期众多研究的主题。由此延伸，心理社会风险在解释早产的种族和族裔差异方面的作用越来越受到关注。与心理社会变量测量相关的几个障碍可能会妨碍我们充分理解它们在解释早产种族差异中的作用。本研究的目的是提出一些选定的测量原则，在调查心理社会因素与早产之间的关系时应考虑这些原则，以便更好地理解早产的种族差异。
