The objective of the present research is to develop and validate the COVID-19 Anxiety Scale (CAS). We conducted three studies to gather evidence regarding content and construct validity, as well to evaluate the reliability of the measure. Study 1 is subdivided into two studies. In Study 1a, we analyze the content validity of the new measure through content expert analysis (N = 10 expert raters). In Study 1b (N = 30), we perform a pilot study with a sample from the target population. In Study 2 (N = 352), we explored the unifactorial structure of the measure, and analyzed its internal consistency verified. Finally, in Study 3 (N = 200), we assess the adequacy of the factor structure and gather evidence on convergent-discriminant validity and gender-scale invariance. In summary, our results demonstrate that CAS is a reliable and adequate instrument to assess COVID-19 related anxiety.
