The measurement of stress in pregnancy

Abstract

Stress is thought to be one of the biopsychosocial factors that contribute to adverse pregnancy outcomes, such as preterm labor and low birthweight. Identification of these factors (as in total number), and measurement of their individually perceived importance (severity) could lead to opportunities for intervention, and improved pregnancy outcome. A pilot study of the Daily Hassles Scale, was conducted in order to determine the appropriateness of its use among pregnant women. Daily hassles were thought to be a valid proxy for prenatal stress. Content and construct validity were determined among a sample of four content experts and 30 pregnant women. The Daily Hassles Scale proved to be a reliable (internally consistent) measure of stress (alpha reliability coefficient of 0.90). Further adaptation of the scale to include hassles specific to pregnancy and further testing of its usefulness among diverse multicultural and ethnic populations is warranted.
