title: Reliability and validity of the 4-item perceived stress scale among pregnant women: results from the OTIS antidepressants study.
abstract: We aimed to estimate the reliability of the 4-item Perceived Stress Scale (PSS) and its validity in 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 Teratology Information Specialists Antidepressants in Pregnancy Cohort. The 4-item PSS demonstrated acceptable internal 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.
