Employing a clustered RCT this paper examines the short-term impact of a 12-month text messaging campaign on health knowledge and practices among CCT beneﬁciaries in Indonesia.
Our analysis reveals that a mHealth information campaign can be an inexpensive and eﬀective tool to (further) improve a diverse range of health indicators. Overall, CCT beneﬁciaries experienced substantial knowledge gains and also showed improved behavior as a result of the intervention. In particular beneﬁciaries with larger social networks and with low initial levels of health knowledge and practices beneﬁted from the campaign. In contrast, we neither ﬁnd evidence for an impact on health outcomes, nor for the role of an individual’s education, cognitive abilities, personality, and bargaining power in mediating the impact of the intervention.
