Abstract
The purpose of the present study was to investigate the effects of efficacy, job satisfaction, job stress and their influence on the occupational commitment of English-medium content teachers. A total of 109 practicing English-medium and Spanish-medium content teachers from the Dominican Republic volunteered to participate in the study. Findings suggest both teacher self-efficacy and collective efficacy measures were inversely but significantly correlated with occupational commitment and positively correlated with job satisfaction. The results also showed significant differences between English-medium and Spanish-medium content teachers’ self-efficacy, job satisfaction, job stress and occupational commitment. These findings have significant implications for advancing theory and practice. Recommendations for further research are discussed.
