To best understand foreign language learning, the present study proposes and tests a conceptual model of confidence in speaking English by examining the path effects of three variables. These three variables are parental psychological control, self-esteem, and language class risk taking. Data were collected from 394 Taiwanese undergraduate students. Structural Equation Modeling (SEM) technique was adopted to examine the path effect in the research model. The results confirmed four significant path effects: (1) parental psychological control negatively predicts self-esteem; (2) self-esteem positively predicts language class risk taking; (3) language class risk taking positively predicts confidence in speaking English; (4) self-esteem positively predicts confidence in speaking English. A mediator was also identified in this model. Language class risk taking was found to mediate the relationship between self-esteem and confidence in speaking English. This study might provide one of the very first empirical findings in the exploration of the relationships among these variables. The findings could help applied psychology researchers understand university EFL learners' parental psychological control, self-esteem, language class risk taking, and confidence in speaking English in psychological, educational and linguistic contexts.
