Psychometric validation of the Prenatal Distress Questionnaire (PDQ) in pregnant women in Spain.

Abstract

The Prenatal Distress Questionnaire (PDQ) was developed among English-speaking women in the United States to assess specific worries and concerns during pregnancy. Our aim was to analyze the factor structure of the PDQ, using confirmatory factor analysis, and assess its convergent validity in Spanish women. A sample of 233 pregnant women with ages ranging from 19 to 42 years in the south of Spain (Europe) (January 2015 - March 2016) completed the translated PDQ, the Perceived Stress Scale (PSS) and the Symptom Checklist-90-revised (SCL-90-R).

The Spanish PDQ significantly correlated with the PSS and SCL-90-R (r's 0.18-0.49, p's
