Background: Perinatal anxiety and depression are common complications during pregnancy. The purpose of this study was to examine the item characteristics, reliability, validity, and factorial structure of the four-item Patient Health Questionnaire-4 (PHQ-4) and to determine the associations between scale scores and sociodemographic factors in a sample of pregnant women from Spain. Method: A total of 845 pregnant women were recruited from two public hospitals in Spain between 2014 and 2016. Participants completed a self-report questionnaire that included Patient Health Questionnaire-4, including the two-item Patient Health Questionnaire and the two-item Generalized Anxiety Disorder Screener. Results: Exploratory and confirmatory factor analysis and scale inter-correlations between the PHQ-4 and PHQ-9 revealed that the PHQ-4 has a bivariate structure and adequately assesses the dimensions of antenatal anxiety and depression. Conclusion: The PHQ-4 is a reliable and valid instrument to screen for depression and anxiety during pregnancy. The PHQ-4 is an ultra-brief measure that can be used to screen for antenatal depression and anxiety to prevent the negative consequences associated with these mental health conditions among mothers and infants.
