Measuring Self-Disclosure Over the Internet

A two-axial measure of disclosure intimacy by Morton (1976, 1978) was expanded to create a new measure usable for linear analyses. Morton's item of "Description" was divided into three "Context" items: Self-Concept, Interpersonal, and Taboo. The other axis of "Evaluation" was divided into four "Expression" items: Detail, Protected, Intensity, and Negativity/Vulnerability. As test data for the measure, demographic information from l50 users' weblogs was compared to free-response disclosures measured with the Morton measure and the linear Context/Expression measure. A multiple regression analysis of profile information versus disclosure intimacy did not reach significance. Results were inconclusive because the measures used in the study suffered from low reliability. Overall, the Context/Expression items were more reliable than the Description/Evaluation axes.
