"In March of 2020, the world was hit by COVID-19, and nearly every country and society around the world is practicing social distancing and placing restrictions on travel and face-to-face interaction. One of the countless impacts of these changes is that nearly all face-to-face research has been temporarily suspended, and many of the organizations conducting this research are exploring shifting some or all of their work to phone-based surveys. We want to help make this transition as seamless as possible and have put together this free guide to help. It captures many of the most important lessons we’ve learned in conducting phone-based surveys since 2014. While it is neither complete nor exhaustive, we hope that it serves as a useful resource to those who need it."
