The hospital anxiety and depression scale (HADS) is a widely used instrument for evaluating psychological distress from anxiety and depression. HADS has not yet been validated in Ethiopia. The aim of this study was to evaluate the reliability and validity of the Amharic (Ethiopian language) version of HADs among HIV infected patients.
The translated scale was administered to 302 HIV/AIDS patients on follow up for and taking anti-retroviral treatment. Consistency assessment was conducted using Cronbach's alpha, test-retest reliability using intra-class correlation coefficients (ICC). Construct validity was examined using principal components analysis (PCA). Parallel analysis, Kaiser's criterion and the scree test were used for factor extraction.
The internal consistency was 0.78 for the anxiety, 0.76 for depression subscales and 0.87 for the full scale of HADS. The intra-class correlation coefficient (ICC) was 80%, 86%, and 84% for the anxiety and depression subscales, and total score respectively. PCA revealed a one dimensional scale.
This preliminary validation study of the Ethiopian version of the HADs indicates that it has promising acceptability, reliability and validity. The adopted scale has a single underlying dimension as indicated by Razavi's model. The HADS can be used to examine psychological distress in HIV infected patients. Findings are discussed and recommendations made.
医院焦虑和抑郁量表（HADS）是一种广泛用于评估焦虑和抑郁引起的心理困扰的工具。HADS 在埃塞俄比亚尚未得到验证。本研究旨在评估接受抗逆转录病毒治疗的 HIV 感染患者中阿姆哈拉语（埃塞俄比亚语）版本 HADs 的信度和效度。
对 302 名接受 HIV/AIDS 随访的患者进行了翻译后的量表评估。使用克朗巴赫α系数进行一致性评估，使用组内相关系数（ICC）进行测试-重测信度评估。使用主成分分析（PCA）进行结构有效性检验。并行分析、凯泽准则和碎石检验用于因子提取。
HADS 的焦虑、抑郁分量表和总分的内部一致性分别为 0.78、0.76 和 0.87。焦虑和抑郁分量表以及总分的 ICC 分别为 80%、86%和 84%。PCA 显示出一个一维量表。
这项 HADs 埃塞俄比亚语版本的初步验证研究表明，它具有良好的可接受性、信度和效度。采用的量表如 Razavi 模型所示，具有单一的潜在维度。HADS 可用于评估 HIV 感染患者的心理困扰。讨论了研究结果并提出了建议。
