The Stroop test for public speaking apprehension: Validity and reliability

This study was designed to test an indirect measure of public speaking apprehension (PSA) because direct measures of public speaking apprehension are problematic in certain circumstances. To this end, participants’ responses to the Stroop Test for Public Speaking Apprehension were correlated with participants’ responses to state communication apprehension (CA), trait CA, imagery control, and dogmatism scales. It was expected that the Stroop Test would be correlated with state and trait CA but not with imagery and dogmatism. Also, since the Stroop Test measures PSA in an indirect fashion, the respondents were not expected to identify the test as a measure of public speaking apprehension. Further, the Stroop Test for PSA was expected to exhibit acceptable test/retest reliability. The data gathered for this study confirmed these expectations. It appears the Stroop Test is an indirect, reliable, and valid way to measure PSA.
