Item‐analysis demonstrated that in the direct negative mode, the two items had low item‐to‐total correlations and that the internal consistency reliability of the sum score could be improved by eliminating the two negatively phrased items. Also, the two negatively worded items defined a separate factor. After they were reworded into a direct positive mode, these two items showed markedly improved item‐to‐total correlations. Moreover, the unique factor disappeared, which suggests that it was a methodological artefact probably attributable to respondent carelessness. Including a few negative items in an otherwise positively stated ques...
