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.
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.
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).
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.
尽管需要可靠的问卷来监测慢性病患者的自我管理情况,但发展中国家缺乏此类工具。本研究旨在对艾滋病毒自我管理低中收入国家问卷进行试点并评估其结构效度。
艾滋病毒自我管理低中收入国家问卷的验证涉及在埃塞俄比亚进行的两项横断面研究。第一轮用于探索性因素分析(EFA),包括261名患者,而第二轮用于验证性因素分析(CFA),包括300名患者。数据使用Kobo Collect电子数据录入模板收集。
样本充足性检验显示值为0.82,情况良好。在第一轮中,32个条目中有6个未被加载,在探索性因素分析中形成了三个因素。其中4个条目被删除,但有2个(PSMB2和PSMB12)因其内容而保留。在第二轮中,对其余28个条目的验证性因素分析因概念重叠又删除了8个条目,最终形成了一份20个条目的问卷。最终条目分为三个维度:认知与幸福感(4个条目)、自我调节(6个条目)和自我管理实践(10个条目)。
该研究将最初的32个条目的艾滋病毒自我管理低中收入国家问卷细化为经过验证的20个条目、具有可接受拟合优度的三维工具。作者建议对新诊断的艾滋病毒患者、治疗效果不佳的患者进行进一步的跨文化和预测性验证及调整。
