We investigate whether RNT, measured transdiagnostically, explains additional variance in symptom severity than worry, rumination, and PEP. We explore whether the content of RNT thoughts or the process of engaging in RNT is associated with symptom severity. Undergraduates (\n                    <jats:italic>n<\/jats:italic>\n                    = 646) completed measures of RNT, PEP, worry, rumination, and symptom severity.
