ABSTRACT
Clatterbuck developed the Attributional Confidence Scale as a way of operationalizing the uncertainty construct developed by Berger and Calabrese. Clatterbuck adhered to three guidelines in his effort to develop a reliable and valid measure of attributional confidence. There are two different versions of the Attributional Confidence Scale (CL7). A 65-item instrument adapted from the Intimacy Scale was designed to measure retroactive attribution. For the CL7, respondents are requested to evaluate how confident they are in giving specific facts about one target person. Clatterbuck summarized the results of 17 studies (N = 1,370) in which the CLUES instrument was used. Clatterbuck recognized that the CL7 was reflective of an American culture and cautioned users that his conceptualization of attributional confidence was “not necessarily the full story”. The CL7 scale has a strong conceptual base and evidence suggests that it is a stable and valid instrument.
