Abstract

Grounded in Bandura’s self-efficacy theory, the present study developed and established validity (content, construct, convergent) and reliability (scale, item) of two new scales: English Public Speaking (EPS) Self-Efficacy Scale (EPSSES) and Sources of EPS Self-Efficacy Scale (SEPSSES). Results of exploratory and confirmatory factor analyses in Sample A (N = 406) confirmed four hypothesized EPS competences gauged by EPSSES, namely: language, topic, organization, and delivery. Similar, results in Sample B (N = 270) supported four sources of EPS self-efficacy gauged by SEPSSES, namely: enactive mastery experience, vicarious experience, verbal persuasion, and physiological and affective state. Correlation analyses in Sample C (N = 263) contributed to the development of self-efficacy theory within the EPS domain. Practical and theoretical implications are discussed.
