The Covid-19 pandemic has affected health systems and economies across the world. Low-income communities have experienced particularly detrimental impacts, as a lack of financial stability further exacerbated augment the crisis. In partnership with the mental health care center SCARF, researchers are conducting a randomized evaluation among low-income adults in Tamil Nadu, India. Can phone-based psychological first aid and temporary cash transfers boost mental health and resilience among low-income households? Do these interventions also improve people’s capacity to engage in preventive health behaviors in the face of Covid-19?
