AI Article Synopsis
- Antenatal depression (AD) is common and can have serious consequences, but there are no specific scales to measure it, leading to the adaptation of existing ones for other contexts.
- The study collected data from pregnant women in Brazil's second trimester and found that 17.34% were depressed, with the BDI being the most effective screening tool, showing high sensitivity and specificity in identifying depression.
- While the findings are relevant, they are limited to a specific population (Brazil) and only cover the second trimester, meaning results may not apply universally due to potential variations in psychometric properties across different populations.
Article Abstract
Background: Antenatal depression (AD) can have devastating consequences. No existing scales are specifically designed to measure it. Common practice is to adapt scales originally developed for other circumstances. We designed this study to validate and determine the psychometric values for AD screening in Brazil.
Methods: We collected clinical and socio-demographic data in the second gestational trimester. The following instruments were also administered during that period: MINI-PLUS, EPDS, BDI and HAM-D.
Results: At the time of assessment, 17.34% of the patients were depressed, and 31.98% met the diagnostic criteria for lifetime major depression. All instruments showed an area under the curve in a receiver operating characteristic analysis greater than 0.85, with the BDI achieving a 0.90 and being the best-performing screening instrument. A score ≥11 on the EPDS (81.58% sensitivity, 73.33% specificity), ≥15 on the BDI (82.00% sensitivity, 84.26% specificity) and ≥9 on the HAM-D (87.76% sensitivity, 74.60% specificity) revealed great dichotomy between depressed and non-depressed patients. Spearman׳s rank correlation coefficients (ρ) among the scales had good values (EPDS vs. BDI 0.79; BDI vs. HAM-D 0.70, and EPDS vs. HAM-D 0.67).
Limitations: This study was transversal, assessing only women in the second gestational trimester. Results may be applicable only to the Brazilian population since psychometric properties may vary with the population under study. Major depression can amplify somatic symptomatology, affecting depressive rating scale data.
Conclusion: AD is highly prevalent in Brazil. To address the problem of under-recognition, physicians can use the EPDS, BDI and HAM-D to identify AD.
