Abstract: | Abstract.— The previously presented (Bohlin & Kjellberg, 1973) inventory of self-reported arousal, which contained four factor analytically derived scales, was further developed in the following way. First, the original factor pattern was cross-validated. Second, a new response scale was constructed which proved to be superior to the old one. Third, the inventory was extended with new items and factor analysis applied to this new inventory. From the model of phenomenological arousal advanced by Bohlin & Kjellberg (1973) six factors were hypothesized and it was shown that a similar solution could be obtained with the extended inventory. Finally, this six-factor pattern was cross-validated and six scales, labelled Sleep-Wakeful-ness, Energy, Stress, Irritation, Euphoria, and Concentration, were constructed. |
