Goldberg's 100 Unipolar Markers
Online version of the 100 Unipolar Markers and Transparent Bipolar Inventory (TBI) developed by Lewis R. Goldberg to measure each of the five domains of the Big Five personality model.
In studies of adjective-anchored bipolar rating scales, a transparent format was found to produce factor markers that were more univocal than the same scales administered in the traditional format. Nonetheless, even the transparent bipolar scales proved less robust as factor markers than did parallel sets of adjectives administered in unipolar format. A set of 100 unipolar terms proved to be highly robust across quite diverse samples of self and peer descriptions.
