摘要

全球有 20 亿人无法使用基本厕所,而卫生条件是决定健康和福祉的关键因素。对卫生项目的评估通常是对疾病或行为进行测量,而视觉模拟量表(VAS)尚未被用于测量用户对其卫生水平的感受。在本研究中,我们评估了横向卫生状况 VAS 的有效性,该量表的编号为 0-10,末端锚点为 "可想象的最佳 "和 "可想象的最差 "卫生状况。在加纳库马西,我们对 291 名参与者在使用集装箱式卫生服务前后的情况进行了调查。在莫桑比克的马普托,我们对之前试验中治疗组的 424 名参与者进行了调查。我们通过测试 VAS 分数与厕所特征之间的假设关联,以及受访者对三种假设卫生状况的评价,评估了构建有效性。我们通过比较有/无卫生设施干预措施的 VAS 来评估响应性。有证据表明(p

Validity of a visual analogue scale to measure and value the perceived level of sanitation - evidence from Ghana and Mozambique.

Two billion people globally lack access to a basic toilet, and sanitation is a critical determinant of health and wellbeing. Evaluations of sanitation programmes typically measure disease or behaviour, and visual analogue scales (VAS) have not been used to measure users' feelings about their level of sanitation. In this study, we assess the validity of a horizontal sanitation VAS numbered 0-10, with end-anchors "best imaginable" and "worst imaginable" sanitation. In Kumasi, Ghana, we surveyed 291 participants before and after uptake of a container-based sanitation service. In Maputo, Mozambique, we surveyed 424 participants from treatment groups of a prior trial. We assessed construct validity by testing hypothesised associations between VAS scores and toilet characteristics, and by respondents valuing three hypothetical sanitation states. We assessed responsiveness by comparing VAS with/without sanitation interventions. There was evidence (p<0.05) for 60% of hypothesised associations in Ghana, and 100% in Mozambique. For responsiveness, there was a 3.4 point increase (2.1 SD) in VAS 10 weeks post-intervention in Ghana, and a 2.9 point difference (1.3 SD) in Mozambique. In valuation exercises, the mean was higher (p<0.001) for the objectively better sanitation state. The sanitation VAS could be useful in economic evaluation to identify which improvements achieve quality of life gains most efficiently. For future studies we recommend a vertical sanitation VAS numbered 0-100 with emojis at end-anchors but retaining a 0-10 option for those who struggle with numeracy.
