Depression in people living with HIV/AIDS is associated with poor health outcomes. Despite this, assessment of depressive symptoms is not a routine clinical practice in the care of people with HIV in Colombia. One reason could be the lack of validated depression screening scales for this population.
To test the reliability and construct validity of the 20- and 10-item-Center for Epidemiological Studies Depression Scale in patients attending an HIV clinic in Cali, Colombia.
A non-random sample of 105 adults was enrolled. The 20 item-CES-D (CES-D-20) scale was administered twice: At baseline and 2-4 weeks later. We calculated the Cronbach's alpha coefficient and the intraclass correlation coefficient. In addition, we used an exploratory and confirmatory factorial analysis, as well as the item response theory to assess the validity of the scale.
Most participants were men (73%), with a mean age of 40 years, 53% of whom had not completed high school. Cronbach's coefficients were 0.92 and 0.94 at baseline and at the second interview, respectively. The intraclass correlation was 0.81 (95% CI: 0.72-0.88). Although all 20 items loaded distinctly in 4 factors, 5 items did not load as expected. The structure factor of the CES-D-20 was not confirmed, as 4 items had poor goodness of fit. The CES-D-10 appeared to perform better in this population.
These results support the reliability and validity of the CES-D-10 instrument to screen for depressive symptoms in people living with HIV in Colombia.
感染艾滋病毒/艾滋病的人群中，抑郁症与健康状况不佳相关。尽管如此，在哥伦比亚，对艾滋病毒感染者的护理中，抑郁症状评估并非常规临床操作。原因之一可能是缺乏针对该人群的经过验证的抑郁症筛查量表。
在哥伦比亚卡利一家艾滋病毒诊所的患者中，测试20项和10项流行病学研究中心抑郁量表的信度和结构效度。
纳入105名成年人的非随机样本。20项CES-D（CES-D-20）量表进行了两次施测：基线时和2至4周后。我们计算了克朗巴哈系数和组内相关系数。此外，我们使用探索性和验证性因子分析以及项目反应理论来评估该量表的效度。
大多数参与者为男性（73%），平均年龄40岁，其中53%未完成高中学业。基线时和第二次访谈时的克朗巴哈系数分别为0.92和0.94。组内相关系数为0.81（95%CI：0.72 - 0.88）。尽管所有20个项目都明显地载荷于4个因子中，但有5个项目的载荷未达预期。CES-D-20的结构因子未得到确认，因为有4个项目的拟合优度较差。CES-D-10在该人群中表现似乎更好。
这些结果支持CES-D-10工具在哥伦比亚艾滋病毒感染者中筛查抑郁症状的信度和效度。
