چکیده (انگلیسی):

The aim of this study is to determine the rate of mental workload on teachers and its correlation with
their quality of life (QOL). In the current study, NASA-task load index (TLX) tool and also a questionnaire of QOL (SF-
36) were used. Results showed that the mean of mental work load between the teachers with two jobs and single job
was significantly different (P<0.05). The mean of mental work load among the teachers with different work hours per
week showed significant positive correlation (P< 0.05). Among the mean mental workload and dimensions of QOL
(activity limitation due to emotional problems and also social performance and general health) were significant
negative correlation (P<0.05). The mean of mental workload score was higher among teachers, which can negatively
impact the teacher’s life quality and also the quality and quantity of their education.
