This study was stochastic sampling. Based on Kregci-Morgan table, 357 peoplewere selected as a sample. Data were collected from teachers who were teaching in schools in the academic year of 93-94. The results of the validation of the method showed that the internal consistency and reliability of the Effort - Reward Imbalance Questionnaire by using Cronbach's alpha was 0.92 and by test-retest method was 0.83. Evaluating the content validity, discrimination, and construct of Effort-Reward Imbalance Questionnaire confirms the validity of the questionnaire. Exploratory and confirmatory factor analyses, as the main form, revealed three correlated but separable dimensions that were effort, reward and over commitment. From the results it can be concluded that Effort-Reward Imbalance Questionnaire is a reliable and valid scale to measure imbalance between effort and reward of teachers.
