Abstract
OBJECTIVE: To revise and test a 34-item self-administered questionnaire that measures health practices important to pregnancy outcome. DESIGN: Three studies were conducted: a content validity study with nurse experts, a content validity study with pregnant women, and a cross-sectional study using mailed surveys to test the reliability and construct validity of the Health Practices in Pregnancy Questionnaire-II (HPQ-II). SETTINGS: Nurse-midwifery and obstetric physician practices. PARTICIPANTS: Clinical experts (n = 8) and pregnant women (n = 10 for Study 2; n = 312 for Study 3). MAIN OUTCOME MEASURE: The HPQ-II, a self-report instrument that measures pregnancy health practices. RESULTS: Content validity was established with two reviews of the HPQ-II conducted by clinical experts and pregnant women and by a satisfactory Content Validity Index. Construct validity was supported by statistically significant correlations with a measure of prepregnancy health practices, scores on individual prepregnancy health practice items, and a theoretically related measure of women's attitudes toward their pregnancies and babies. Reliability (internal consistency) was satisfactory. CONCLUSIONS: This instrument promises to be useful in research and practice involving health practices during pregnancy.
