Evaluating the factor structure of the pregnancy-related anxiety scale: implications for maternal and infant wellbeing.

Aims/background: Although the Pregnancy-Related Anxiety Scale - also referred to as the Pregnancy-Related Thoughts Scale (PRT) - is one of the most widely utilised measures of pregnancy-related anxiety (PrA), there is limited research exploring its factor structure and psychometric properties. The present study sought to (a) explore the factor structure of the PRT and (b) examine whether specific dimensions of PrA differentially predict postpartum outcomes.

Design/methods: A community sample of pregnant women ( = 159) was recruited from a Midwestern city in the United States and completed the PRT alongside other self-report measures of stress and maternal health and mood during pregnancy.
