Millions of people in Bangladesh drink arsenic-contaminated water despite increased awareness of consequences to health. Theory-based and evidence-based interventions are likely to have greater impact on people switching to existing arsenic-safe wells than providing information alone. To test this assumption, we first developed interventions based on an empirical test of the Risk, Attitudes, Norms, Abilities and Self-regulation (RANAS) model of behaviour change. In the second part of this study, a cluster-randomised controlled trial revealed that in accordance with our hypotheses, information alone showed smaller increases in switching to arsenic-safe wells than information with reminders or information with reminders and implementation intentions.
尽管人们对健康后果的认识有所提高，但孟加拉国仍有数百万人饮用受砷污染的水。与单纯提供信息相比，基于理论和证据的干预措施可能会对人们改用现有的无砷安全水井产生更大影响。为了验证这一假设，我们首先基于行为改变的风险、态度、规范、能力和自我调节（RANAS）模型的实证测试制定了干预措施。在本研究的第二部分，一项整群随机对照试验表明，根据我们的假设，与带有提醒信息或带有提醒信息及实施意图的情况相比，单纯的信息在改用无砷安全水井方面的增加幅度较小。
