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 個產後婦女，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，再由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 ascreening tool for detecting pre-and postpartum depression. One hundred andthirty-five pregnant women and 132 postpartum women were screened for majordepression by BDI using cut-off point of 10. Two samples of possible cases andnon-cases completed further diagnostic interviews using SADS-L and SADS. Using acut-off point of 10. the BDI showed sensitivity of 100% and specificity of 78%in prospectively detecting major depression and sensitivity of 83% andspecificity of 86% in minor depression. The appropriateness of Various cut-offscore of BDI was also evaluated in this study.
