Diagnostic Accuracy of the Composite International Diagnostic Interview (CIDI 3.0) PTSD Module Among Female Vietnam-Era Veterans

The World Health Organization (WHO) Composite International Diagnostic Interview (CIDI) posttraumatic stress disorder (PTSD) module is widely used in epidemiological studies of PTSD, yet relatively few data attest to the instrument's diagnostic utility. The current study evaluated the diagnostic utility of the CIDI 3.0 PTSD module with U. S. women Vietnam‐era veterans. The CIDI and the Clinician‐Administered PTSD Scale (CAPS) were independently administered to a stratified sample of 160 women, oversampled for current PTSD. Both lifetime PTSD and recent (past year) PTSD were assessed within a 3‐week interval. Forty‐five percent of the sample met criteria for a CAPS diagnosis of lifetime PTSD, and 21.9% of the sample met criteria for a CAPS diagnosis of past‐year PTSD. Using CAPS as the diagnostic criterion, the CIDI correctly classified 78.8% of cases for lifetime PTSD (κ = .56) and 82.0% of past year PTSD cases (κ = .51). Estimates of diagnostic performance for the CIDI were sensitivity of .61 and specificity of .91 for lifetime PTSD and sensitivity of .71 and specificity of .85 for past‐year PTSD. Results suggest that the CIDI has good utility for identifying PTSD, though it is a somewhat conservative indicator of lifetime PTSD as compared to the CAPS. 抽象 Traditional and Simplified Chinese s by AsianSTSS 標題：女越南戰事退役軍中綜合國際診斷會見(CIDI 3.0) 的診斷準確性 撮要：世界衛生組織(WHO)綜合國際診斷會見(CIDI)創傷後壓力症(PTSD)單元被廣泛應用於PTSD流行學研究，但只有少數研究其相關診斷效用。本研究在女性越南戰事退役軍中評定CIDI 3.0 PTSD單元的診斷效能。這是160名女士的分層和過度採樣現有PTSD的樣本，然後獨立地施行CIDI 和醫生施行PTSD量表(CAPS)。在三週內使用評估其終生PTSD和現有(過去一年)PTSD。總數45.0%符合CAPS終生PTSD診斷準則，和21.9%為CAPS過去一年PTSD診斷準則。以CAPS為診斷標準，CIDI 正確判別78.8% 終生PTSD個案(K= .56)和82.0% 過去一年PTSD 個案(K= .51) 。利用CAPS為標準估計CIDI的診斷表現，終生PTSD的靈敏度為.61和特異性為.091，而過往一年PTSD的靈敏度是.71 和特異性是.85。結果確認CIDI對辨識PTSD有高效用，但對比CAPS在終生PTSD方面卻是較保守的指標。 标题：女越南战事退役军中综合国际诊断会见(CIDI 3.0) 的诊断准确性 撮要：世界卫生组织(WHO)综合国际诊断会见(CIDI)创伤后压力症(PTSD)单元被广泛应用于PTSD流行学研究，但只有少数研究其相关诊断效用。本研究在女性越南战事退役军中评定CIDI 3.0 PTSD单元的诊断效能。这是160名女士的分层和过度采样现有PTSD的样本，然后独立地施行CIDI 和医生施行PTSD量表(CAPS)。在三周内使用评估其终生PTSD和现有(过去一年)PTSD。总数45.0%符合CAPS终生PTSD诊断准则，和21.9%为CAPS过去一年PTSD诊断准则。以CAPS为诊断标准，CIDI 正确判别78.8% 终生PTSD个案(K= .56)和82.0% 过去一年PTSD 个案(K= .51) 。利用CAPS为标准估计CIDI的诊断表现，终生PTSD的灵敏度为.61和特异性为.091，而过往一年PTSD的灵敏度是.71 和特异性是.85。结果确认CIDI对辨识PTSD有高效用，但比对CAPS在终生PTSD方面却是较保守的指标。
