Validation of the Non-Ah Speech Disturbance Ratio as a Measure of Transitory Anxiety

Validation of the Non-Ah Speech Disturbance Ratio as a Measure of Transitory Anxiety

Date: December 1974
Creator: Hartwig, Fenton W.
Description: An investigation of concurrent validity of the Non-ah Speech Disturbance Ratio (Non-ah SDR) with the State Form of the State-Trait Anxiety Inventory (STAI). Twenty male college students talked on an anxiety-arousing topic before female audiences who rated observed anxiety. Each subject completed the State and Trait Forms of the STAI. Reliabilities were, by the Intraclass correlation for Raters on Day 1, .63 (p<.01) and Day 2, .20 (p<.05). Pearson's r for scorers was .98 (p<.01). The Non-ah SDR and all other measures of anxiety correlated. A partial correlation test found the naive ratings significantly determined by manifest speech disturbance, as measured by the Non-ah SDR. Certain categories of speech disturbance were only infrequently utilized and added little to the measure as a whole.
