Administered the Center for Epidemiologic Studies Depression Scale and episodic stressor and strain scales to 255 female newly appointed teachers. Job conditions were related to postemployment depressive symptoms independently of pre-employment symptoms and other risk factors. Ss who worked in the most adverse school environments showed the most depressive symptoms; Ss in schools with the best conditions tended to show the fewest symptoms. The effects of working conditions on symptoms were relatively immediate. There may be positive mental health effects, in relation to preemployment levels, associated with teaching in benign school environments. Suggestions for future progress in teacher-stress research include the use of neutral self-reports to assess school conditions and a greater reliance on standardized instruments to measure independent and dependent variables.
