Abstract

Introduction: Despite the need for reliable questionnaires to monitor self-management in chronic disease patients, such tools are lacking in developing countries. This study aims to pilot and assess the construct validity of the HIV-SM LMIC questionnaire.

Method: The validation of the HIV-SM LMIC questionnaire involved two cross-sectional studies in Ethiopia. The first round, for exploratory factor analysis (EFA), included 261 patients, while the second round, for confirmatory factor analysis (CFA), included 300 patients. Data was collected using the Kobo Collect electronic data entry template.

Result: The sample adequacy test showed a good value of 0.82. In the first round, 6 of the 32 items were not loaded, forming three factors in the EFA. Four of these items were dropped, but two (PSMB2 and PSMB12) were retained for their content. In the second round, CFA on the remaining 28 items led to dropping 8 more items due to conceptual overlap, resulting in a 20-item questionnaire. The final items were structured into three dimensions: awareness and well-being (4 items), self-regulation (6 items), and self-management practices (10 items).

Conclusion: The study refined the original 32-item HIV-SM LMIC questionnaire to a validated 20-item, three-dimensional tool with an acceptable goodness of fit. The authors recommend further cross-cultural and predictive validation and adaptation for newly diagnosed HIV patients, those with poor treatment outcomes.

中低收入国家HIV- sm中低收入人群自我管理问卷的因素结构
导言:尽管需要可靠的问卷来监测慢性病患者的自我管理,但发展中国家缺乏这样的工具。本研究旨在预试及评估HIV-SM LMIC问卷的建构效度。方法:在埃塞俄比亚进行两项横断面研究,验证HIV-SM LMIC问卷。第一轮为探索性因素分析(EFA),纳入261例患者;第二轮为验证性因素分析(CFA),纳入300例患者。使用Kobo Collect电子数据录入模板收集数据。结果:样本充分性检验值为0.82。在第一轮中,32个项目中有6个没有加载,形成了EFA中的三个因素。其中四个条目被删除,但两个条目(PSMB2和PSMB12)的内容被保留。在第二轮中,由于概念重叠,CFA对剩余的28个项目又减少了8个项目,形成了一个20个项目的问卷。最后的项目分为三个维度:意识和幸福感(4个项目),自我调节(6个项目)和自我管理实践(10个项目)。结论:该研究将原来的32项HIV-SM LMIC问卷改进为经过验证的20项三维工具,具有可接受的拟合优度。作者建议对新诊断的HIV患者进行进一步的跨文化和预测性验证和适应,这些患者治疗效果较差。
