ABSTRACT Household water treatment (HWT) can tackle the issue of consuming unsafe drinking water at home. While household socio-economic characteristics are often assumed to influence the psychology of HWT use, no study has rigorously tested such an assumption. We aim to fill the gap by a cross-sectional study in a rural area in Sumba Timur, Indonesia (N = 256). Using mediation analysis, we demonstrated that psychosocial factors mediated the relationship between socio-economic characteristics and the use of household water treatment, and socio-economic characteristics strongly influenced the psychology of household water treatment usage. The use of HWT asked from different angles allowed more degrees of freedom to better assess the true status of the HWT usage, via the principal component of the answers. This paper concludes that “causal” relationship pathway from socio-economic characteristics to the use of HWT via psychosocial factors is a realistic assumption when assessing the influence of socio-economic characteristics on HWT.

社会经济特征通过心理社会因素对家庭水处理使用的影响：中介分析

摘要 家庭水处理 (HWT) 可以解决在家中饮用不安全饮用水的问题。虽然通常假设家庭社会经济特征会影响 HWT 使用的心理，但没有研究严格测试过这种假设。我们的目标是通过在印度尼西亚松巴帖木儿（N = 256）的农村地区进行横断面研究来填补这一空白。使用中介分析，我们证明心理社会因素在社会经济特征与家庭水处理使用之间的关系中起中介作用，而社会经济特征强烈影响家庭水处理使用的心理。从不同角度询问 HWT 的使用允许更多的自由度，通过答案的主成分更好地评估 HWT 使用的真实状态。
