Abstract: Objective. To evaluate various formats for the communication of prenatal test results. Design. In study 1 ( N= 400), female students completed a questionnaire assessing risk perception, affect, and perceived usefulness of prenatal test results. A randomized, 2 (risk level; low, high) × 4 (format; ratio with numerator 1, ratio with denominator 1000, Paling Perspective Scale, pictograms) design was used. Study 2 ( N= 200) employed a 2 (risk level; low, high) × 2 (format; Paling Perspective Scale, risk comparisons in numerical format) design. Results. In study 1, the Paling Perspective Scale resulted in a higher level of perceived risk across different risk levels compared with the other formats. Furthermore, participants in the low-risk group perceived the test results as less risky compared with participants in the high-risk group ( P
