本研究旨在評估貝氏憂鬱量表(BDI)用在篩選周產期憂鬱症的信效度及不同分割點之適用性。在某醫學中心取樣135個產前與132個産後歸女,先以貝氏憂鬱表10分為篩選工具篩選出可能為憂鬱組的個案與非憂鬱組的個案,再向其中各取樣部分樣本以半結構化晤談表進行診斷晤談,以確立診斷;結果發現貝氏憂鬱表具有滿意的內部一致性信度,且能區分出嚴重型憂鬱症與未達嚴重型憂鬱症之輕型憂鬱症者。應用於篩選時,以10分篩選嚴重型憂鬱症,可達100%敏感度,但特異性只達78%;若篩選憂鬱程度較輕之憂鬱者,10分之敏感度為83%,特異性為86%。本研究另外建立了不同分割點之敏感度、特異性及正確率等值以供不同篩選目的時之參考。
This study was designed to evaluate the appropriateness of BDI as a screening tool for detecting pre- and postpartum depression. One hundred and thirty-five pregnant women and 132 postpartum women were screened for major depression by BDI using cut-off point of 10. Two samples of possible cases and non-cases completed further diagnostic interviews using SADS-L and SADS. Using a cut-off point of 10, the BDI showed sensitivity of 100% and specificity of 78% in prospectively detecting major depression and sensitivity of 83% and specificity of 86% in minor depression. The appropriateness of various cut-off score of BDI was also evaluated in this study.
