A study examined the effects of rational-emotive therapy (RET) and visualization as interventions to reduce communication apprehension as measured by the Personal Report of Communication Anxiety-25. Forty-seven undergraduate students were randomly assigned to one of three groups: RET, visualization, or an attention-placebo group. The RET group listened to a 20-minute audio-tape of a male voice disputing irrational beliefs. A second experimental group, the visualization group, listened to the same voice, disputing the same irrational beliefs using visualization techniques. The control group listened to the same voice discussing a neutral topic. A repeated measures design was used to look at reduction in communication apprehension across three assessments. No significant group effect was found. Findings suggest that neither visualization nor RET produced a significant reduction in communication apprehension when compared to the control group.
