Abstract
Improving public trust in public health services is a challenge in many developing countries. One of the possible reasons behind this may be low level of public trust in public health services. This study aims to clarify whether providing truthful positive information about public health services can improve people’s trust in public health services.

Experimental Design

Experimental Design
We plan to randomly provide truthful positive information about public health services.
Experimental Design Details
The sample will be randomly divided into either treatment1, treatment2 or a control group. We will measure trust at baseline for all participants and subsequently randomly provides them with positive information about public health services. We then measure how this information changes their trust. In addition to the questionnaire, following Acemoglu et al. (2020), we use fund dictator game to measure trust.

It gives our respondents a choice between allocating money in an envelope between themselves and a fund that helps people in the country who want to go to public health facilities to cure their illness. They then make a similar decision for a fund that helps people who want to go to private health services using a separate envelope of money.
Randomization Method
The recruitment of participants will be conducted using random street intercept.
When the enumerator finds the participant, the enumerator will bring the participant to the reception desk.
At the reception desk, we will prepare a list of treatment 1, treatment 2 and control randomly assigned to the registration number, which will be done in the office by a computer. Therefore, randomization is made when the participant registers for the survey.
