Assessment of studies based on the use of questionnaires in the time of Covid-19 pandemic.

During the covid-19 pandemic a huge number of research projects have been promoted internationally, nationally and locally. This also happened in Italy which was the first affected European country. Among these studies, research protocols based on the use of online questionnaires to evaluate the reaction of health workers and researchers to the emergency situation and their state of well-being were promoted. This contribution focuses on research protocols based on the use of online questionnaires and presents as a case study three different research proposals with the purpose of showing their different degree of compliance to scientific and ethical requirements and the need for a clear regulation. A guideline for the assessment of studies based on questionnaires is then suggested, in the absence of a national regulation on the issue. Having established rules, albeit flexible, can help to guarantee transparency in the evaluation process and contribute to the scientific and ethical compliance of the research.
