As revealed by literature, anxiety and stress are complicated yet serious issues among teachers at all educational levels. Though widely studied, research on them often focuses on pre-service or primary and middle school teachers, with little research on in-service university teachers. It is especially so in China. The present study thus examined anxiety, stress and their relations with demographic variables in in-service university teachers in China. 256 teachers from various universities in China answered the Demographic Questionnaire, the Teaching Anxiety Scale and the Teacher Stress Inventory. Analyses of the data revealed the following main findings: (1) the participants were under great stress, but they were generally not so anxious about teaching, (2) teaching anxiety was generally significantly negatively correlated with age, professional title and years of teaching, while teacher stress was significantly negatively related to professional title, and (3) overall teacher stress, professional title and age were powerful predictors for teaching anxiety, while years of teaching, overall teaching anxiety and its subscales were powerful predictors for teacher stress. Based on these findings, some implications are discussed.
