Survey items can separately measure enthusiasm and anxiety toward candidates

Evidence

We presented the respondent with a modified feeling thermometer anchored by pairs of words connoting anxiety versus safety or, alternatively, enthusiasm versus depression. In order to obtain a minimal validation test, we chose two pairs for each dimension. The enthusiasm pairs were (enthusiastic vs. unenthusiastic) and (interested vs. indifferent) and the anxiety pairs were (upset vs. comfortable) and (anxious vs. safe). — John T.
