Can we identify mothers at-risk for postpartum anxiety in the immediate postpartum period using the State-Trait Anxiety Inventory?

AbstractBackground tudy assessed the stability of maternal anxiety and concordance between State-Trait Anxiety Inventory (STAI) scores in the immediate postpartum period to 8 weeks postpartum. s lation-based sample of 522 mothers completed the STAI at 1, 4, and 8 weeks postpartum. Sensitivity, specificity, and predictive power of the 1-week STAI in relation to identifying mothers with elevated STAI scores at 4 and 8 weeks was determined. Predictive power of the STAI was further assessed using odds ratios and receiver operator characteristic (ROC) curves. s eek postpartum, 22.6% of mothers scored >40 on the STAI, decreasing to 17.2% at 4 weeks and 14.8% at 8 weeks. Using the cut-off score of >40, the 1-week STAI accurately classified 84.0% mothers at 4 weeks and 83.6% at 8 weeks with or without anxiety symptomatology. The 1-week STAI was significantly correlated to the 4-week (r=0.68, p<0.001) and 8-week (r=0.64, p<0.001) STAI. Mothers with a 1-week STAI score >40 were 15.2 times more likely at 4 weeks (95% CI=8.9−26.1) and 14.0 times more likely at 8 weeks (95% CI=7.9–24.8) to exhibit postpartum anxiety symptomatology. tions atric interviews were not completed in collaboration with the STAI and specific types of anxiety disorders were not identified. sions off score of >40 on the STAI administered early in the postpartum period is recommended in a 2-phase identification program in order to not miss mothers with postpartum anxiety.
