Predictors of maternal state anxiety on arrival at a Japanese hospital outpatient clinic: a cross-sectional study.

There is potential for improved understanding of the predictors of maternal state anxiety to aid in the development of materials that would best measure anxiety. The present findings may also suggest some means of providing appropriate information and support to anxious mothers. Our findings cannot demonstrate causation, however, and teaching methods and supportive practices were not investigated; therefore, a qualitative study on the concrete content of maternal anxiety and an intervention study to create support services for anxious mothers is required. In addition, prospective or longitudinal studies are also important for investigating causation.
