The influence of self-consciousness on the internal consistency of different scales

The present study showed that individuals high in private self-consciousness provide self-reports of greater internal consistency (Cronbachʹs α) than individuals low in private self-consciousness. A highly significant difference was observed for the scales satisfaction and self-representation. An almost significant difference was found for the scale inner speech. However, no significant differences were found for the scales public self-consciousness and ill-being. All together the data support the hypothesis that subjects high in private self-consciousness have an extensive and precise knowledge of themselves. Therefore, they can answer the items of a personality questionnaire consistently. These findings clearly imply that it is more probable to find significant correlations among variables for subjects high in self-connsciousness than for subjects low in self-consciousness.
