Public speaking has become an increasingly sought-after skill, which is why more and more people choose to get professionally trained. But is it possible for a public speaking program to have other effects, in addition to improved performance? The aim of this study is to discover the effects of a public speaking program on reducing social anxiety, public speaking anxiety and shame, and also on increasing self-efficacy. The sample (high-school and university students) consisted of 164 participants aged between 15 and 47 years, M = 19.93, SD = 4.70. There were 82 participants in the experimental group and 82 participants in the control group, and the instruments used were: Liebowitz's Scale for Social Anxiety (Liebowitz, 1987), Personal Report on Public Speaking Anxiety (McCroskey, 1970), General scale of self-efficacy (Schwarzer & Jerusalem, 1995), Cognitive Schema Questionnaire (Young, 2005). A test-retest design was approached, the participants completing the questionnaires one week apart from the others. The results indicate that a public speaking program is useful for reducing social anxiety and public speaking anxiety, with significant differences between the experimental and control groups. However, in terms of self-efficacy and shame, the results were not conclusive. Thus, even if there has been a decrease in shame and an increase in self-efficacy, it is not clear whether these changes can be attributed to the proposed program. This study can serve as the beginning of a program that can contribute to reducing the level of social anxiety and public speaking anxiety..
