Researchers have been looking into the stressful nature of teaching for quite some time. Kyriacou (2001) maintains that teaching is one of the top five most stressful careers, while Stoeber and Rennert (2018) indicate that teachers exhibit a higher level of stress than any other profession (Bowen, 2016, p. 1205). Much educational and psychological research has been written about teacher stress, and several have shown links between teacher stress and turnover and the high cost that entails. Teacher stress can also impact the quality of education. Although most studies of teacher stress have been conducted in Western societies, this study focuses on the causes of teacher stress and its relationship to motivation performance in Middle Eastern society, specifically in Saudi Arabia. In this study, Saudi Arabian teachers (N=114, male and female) were administered a self-reported Teacher Stress questionnaire (Ferguson et al., 2017) as well as a 16-item Types of Motivation Questionnaire (Roth et al., 2007). The study sought to answer the following central research hypotheses: 1. The study hypothesized that various clusters of motivation of teachers vary across different levels of stress. 2.1 Teacher's socio-demographic variables (gender and type of teacher (one vs. all subjects) and qualification (BA, MA, & Ph.D.) have significantly impact on teacher stress. 2.2 Teachers' age and experience (number of years taught) significantly predict their stress after controlling for gender and qualification. 2.3 The study anticipated that teachers' motivation would vary as a function of sociodemographic variables such teachers' gender, type of teacher (one vs. all subject), years taught and qualification (BA, MA, & Ph.D.). 2.4 Teachers' age and experience (the number of years taught) significantly predict their motivation after controlling for gender and qualification. 3.0 The study hypothesized that the higher teacher's autonomous motivation, the less stress teacher experience. Whereas higher teachers controlled motivation would be related to higher teacher stress. [The dissertation citations contained here are published with the permission of ProQuest LLC.
