Depression is a common comorbidity in patients with coronary artery disease (CAD), which often remains undetected and untreated. This study aimed to examine the psychometric properties of the Depression Module of the Patient Health Questionnaire (PHQ-9) on a sample of cardiac patients in Iran. Method: The Persian version of the PHQ-9 was developed and administered to 150 patients with CAD, admitted to a tertiary hospital in Tehran, Iran. The major depression module of the International Neuropsychiatric Interview (MINI) was used as the gold standard for the diagnosis of depression. The Persian PHQ-9 demonstrated acceptable internal consistency, with Cronbach's alpha coefficient of 0.80. The optimal cut-off score of ≥7 showed a sensitivity of 76, specificity of 78, and the area under curve of 0.82. The Persian PHQ-9 has acceptable psychometric properties to screen for and detect a current depressive episode in patients with CAD, with recommended cut-off score of ≥7.
抑郁症是冠状动脉疾病（CAD）患者中常见的合并症，通常仍未被发现和治疗。本研究旨在检验患者健康问卷（PHQ - 9）抑郁模块在伊朗心脏病患者样本中的心理测量特性。方法：开发了波斯语版的PHQ - 9，并对150名入住伊朗德黑兰一家三级医院的CAD患者进行了问卷调查。国际神经精神访谈（MINI）的重度抑郁模块被用作抑郁症诊断的金标准。波斯语版PHQ - 9显示出可接受的内部一致性，克朗巴哈α系数为0.80。最佳截断分数≥7时，灵敏度为76，特异度为78，曲线下面积为0.82。波斯语版PHQ - 9具有可接受的心理测量特性，可用于筛查和检测CAD患者当前的抑郁发作，推荐截断分数为≥7。
