Communication apprehension: An assessment of Australian and United States data

Abstract

This study assessed the claims of unidimensionality for a measure of oral communication apprehension (Personal Report of Communication Apprehension). Eighteen independent samples, drawn from Australian and United States sources were used; and comparisons were made between the samples. Although similarities were found among the data sets with respect to internal consistency, frequency distributions, and item-total correlations, the claim of unidimensionality in the measure was rejected. It was also found that there were no overall differences between Australian and United States samples, no sex differences, and no age differences.
