背景资料：流行病学研究中心抑郁量表（CES-D-10）是一种抑郁症筛查工具，已用于南非国民收入动态研究（NIDS），这是一项全国家庭小组研究。这一筛选工具尚未在南非得到验证。本研究旨在建立祖鲁语、科萨语和南非荷兰语CES-D-10的信度和效度。CES-D-10的心理测量特性进行了比较，病人健康问卷（PHQ-9），抑郁症筛查工具已经验证在SouthAfrica. Methods：分层随机样本的科萨语，南非荷兰语和祖鲁语的参与者年龄在15岁或以上（N = 944）被招募从开普敦地铁和Ethekwini区。面对面访谈包括社会人口统计学问题、CES-D-10、患者健康问卷（PHQ-9）和WHO残疾评估量表2.0（WHODAS）。重度抑郁症是使用迷你国际神经精神访谈。所有文书均已翻译并回译为英文。结构效度采用探索性因素分析与方差最大旋转。结果：祖鲁族、南非荷兰语和科萨语样本中抑郁症的检出率分别为6.6%、18.0%和6.9%。与PHQ-9和WHODAS相比，CES-D-10在样本间具有可接受的内部一致性（α = 0.69 - 0.89），并且具有足够的并行有效性。CES-D-10受试者操作特征曲线下面积为良好至极好：祖鲁语为0.81（95% CI 0.71 - 0.90），南非荷兰语为0.93（95% CI 0.90 - 0.96），科萨语为0.94（95% CI 0.89 - 0.99）。祖鲁语、南非荷兰语和科萨语的临界值分别为12、11和13，产生了最平衡的灵敏度、特异性和阳性预测值（祖鲁语：71.4%、72.6%和16.1%;南非荷兰语：84.6%、84.0%、53.7%;科萨语：81.0%、95.0%、54.8%）。这些数值略高于PHQ-9产生的数值。CES-D-10和PHQ-9，否则执行类似的跨samples.Conclusions：CES-D-10是一个有效的，可靠的筛选工具，抑郁症在祖鲁，科萨和有色南非荷兰语人群。
Background: The 10-item Centre for Epidemiological Studies Depression Scale (CES-D-10) is a depression screening tool that has been used in the South African National Income Dynamics Study (NIDS), a national household panel study. This screening tool has not yet been validated in South Africa. This study aimed to establish the reliability and validity of the CES-D-10 in Zulu, Xhosa and Afrikaans. The CES-D-10's psychometric properties were also compared to the Patient Health Questionnaire (PHQ-9), a depression screening tool already validated in South Africa.Methods: Stratified random samples of Xhosa, Afrikaans and Zulu-speaking participants aged 15 years or older (N = 944) were recruited from Cape Town Metro and Ethekwini districts. Face-to-face interviews included socio-demographic questions, the CES-D-10, Patient Health Questionnaire (PHQ-9), and WHO Disability Assessment Schedule 2.0 (WHODAS). Major depression was determined using the Mini International Neuropsychiatric Interview. All instruments were translated and back-translated to English. Construct validity was examined using exploratory factor analysis with varimax rotation. Receiver Operating Characteristics (ROC) curves were used to investigate the CES-D-10 and PHQ-9's criterion validity, and compared using the DeLong method.Results: Overall, 6.6, 18.0 and 6.9% of the Zulu, Afrikaans and Xhosa samples were diagnosed with depression, respectively. The CES-D-10 had acceptable internal consistency across samples (alpha = 0.69-0.89), and adequate concurrent validity, when compared to the PHQ-9 and WHODAS. The CES-D-10 area under the Receiver Operator Characteristic curve was good to excellent: 0.81 (95% CI 0.71-0.90) for Zulu, 0.93 (95% CI 0.90-0.96) for Afrikaans, and 0.94 (95% CI 0.89-0.99) for Xhosa. A cut-off of 12, 11 and 13 for Zulu, Afrikaans and Xhosa, respectively, generated the most balanced sensitivity, specificity and positive predictive value (Zulu: 71.4, 72.6% and 16.1%; Afrikaans: 84.6%, 84.0%, 53.7%; Xhosa: 81.0%, 95.0%, 54.8%). These were slightly higher than those generated for the PHQ-9. The CES-D-10 and PHQ-9 otherwise performed similarly across samples.Conclusions: The CES-D-10 is a valid, reliable screening tool for depression in Zulu, Xhosa and coloured Afrikaans populations.
