We aimed to estimate the reliability of the 4-item Perceived Stress Scale (PSS) and its validity predicting maternal depression and quality of life (QoL). Data regarding stress, depression and QoL were collected during pregnancy among a sub-sample from the Organization of Teratologyformation Specialists Antidepressants Pregnancy Cohort. The 4-item PSS demonstrated acceptableternal consistency (Cronbach's alpha coefficient=.79), alternate forms stability reliability with the 10-item PSS (Pearson correlation coefficient r=.63; p<.001), convergent validity with the Edinburgh Postnatal Depression Scale (r=.67; p<.001), and concurrent validity with the mental health component of the Short-Form-12 (r=-.62; p<.001) as a measure of QoL. The 4-item PSS is a valid and useful tool for assessing maternal stress during pregnancy.
