Primary Outcomes (explanation)
Beliefs Index: A sum of nine binary variables that indicate whether or not an individual knows each of nine symptoms of Covid-19, and six binary variables that measure subjects’ beliefs related to Covid-19. The binary variables capturing beliefs are constructed using data collected on a 3-point scale: “Yes”, “Don’t Know”, and “No”. The “Don’t Know” option will be coded as zero. This index is an outcome to be measured both before and after the intervention.
Below is a description of how variables are encoded to create the Beliefs Index:
- Knows the symptom: Cough [No = 0, Yes = 1]
- Knows the symptom: Fever [No = 0, Yes = 1]
- Knows the symptom: Breathing Difficulty [No = 0, Yes = 1]
- Knows the symptom: Congestion in nose and throat [No = 0, Yes = 1]
- Knows the symptom: Runny nose [No = 0, Yes = 1]
- Knows the symptom: Feeling tired [No = 0, Yes = 1]
- Knows the symptom: Body aches [No = 0, Yes = 1]
- Knows the symptom: Diarrhoea [No = 0, Yes = 1]
- Knows the symptom: Loss of taste or smell [No = 0, Yes = 1]
- If someone does not show any symptom of the novel coronavirus, could they still have the disease? [No = 0, Don’t Know = 0, Yes = 1]
- Do you think there is any medicine or herb that helps against the novel coronavirus? [Yes = 0, Don’t Know = 0, No = 1]
- Suppose a person you know has symptoms of the novel coronavirus. Would you advise them to take antibiotics? [Yes = 0, Don’t Know = 0, No = 1]
- Would you advise them to drink cow’s urine? [Yes = 0, Don’t Know = 0, No = 1]
- If a person takes turmeric every day, do you think they will be less likely to get the novel coronavirus? [Yes = 0, Don’t Know = 0, No = 1]
- Do you think people of some religions are more likely to spread the novel coronavirus? [Yes = 0, Don’t Know = 0, No = 1]
We will also create a weak version of the belief index that is less absolute in that “Yes”, “No”, and “Don’t Know” will be coded as ternary variables with values -1, 1, and 0 rather than binary variables with values 0 and 1 only. We will do this in order to measure less definitive changes in belief, which are nonetheless important.
Mental Health Index (PHQ4): A sum of four questions about mental health on a four-point scale (0 to 3). This index is an outcome to be measured both before and after the intervention. Below is a description of how variables are encoded to create the Mental Health Index (PHQ-4):
- How often do you have little interest or pleasure in doing things? [Not at
all = 0, Several Days = 1, More than half the days = 2, Nearly everyday
= 3]
- How often do you feel down, depressed or hopeless? [Not at all = 0, Several Days = 1, More than half the days = 2, Nearly everyday = 3]
- How often do you feel nervous, anxious, or on edge? [Not at all = 0, Several Days = 1, More than half the days = 2, Nearly everyday = 3]
- How often do you feel like you are not able to stop or control worrying? [Not at all = 0, Several Days = 1, More than half the days = 2, Nearly everyday = 3]
