Information during crises can be a double-edged sword - essential to dispel misinformation, and often a cause for anxiety. Anxiety, in turn, can lead to poor decisions. Against such a backdrop, how can information be delivered responsibly, mitigating the anticipated risks?
In this experiment, we ask whether information on COVID-19 can be delivered without negative consequences to mental health.
Between June and August of 2020, we recruited internal migrants employed in the Indian garment industry to participate in the study. Internal migrants are an important population because they could be at a higher risk of contracting COVID-19 during return migration, and could infect their families.
We selected individuals from an administrative dataset of 23 factories in Karnataka. Since some individuals declined to participate, we were left with 914 individuals at baseline, 57 percent of whom were female. The sample was young with an average age of 24 years.
We first measured their knowledge of COVID-19 and screened them for depression and anxiety. We then randomly assigned them to receive information pertaining to COVID-19 via one of three modes:
About 20 percent of participants were assigned to receive text messages, and the rest were split between pre-recorded audio and phone calls. The content of the message remained unchanged for all three modes.
We had two outcomes of interest— knowledge and mental health.
Baseline data confirmed that there was substantial misinformation among participants.
About 18 percent of the sample was attrited between baseline and endline.
Given the rise in stress, anxiety and depression during the COVID-19 pandemic, the mental health consequences of risk communication demand attention. We demonstrate that, for under $0.25 per message, phone calls can broadcast information at least as effectively as conventional methods, yet with better consequences for mental health.
