Longitudinal Measurement of Work Stressors in Pregnancy.

PB2012105521

Publication Date	2009
Personal Author	Meyer, J. D.; Warren, N.; Nichols, G.; Mahooti-Brooks, N.

Abstract	The overall goals of this developmental and planning grant were to obtain preliminary data assessing two models of occupational stress during pregnancy, in particular measuring repeatedly and longitudinally across the course of pregnancy to evaluate the possibility that work stress may change across pregnancy. This proposal aims also to evaluate the use of the effort-reward imbalance (ERI) model, which has not been tested in pregnant workers or used in studies of pregnancy outcomes. As sufficient data do not exist on the measurement and range of these exposures during pregnancy, or in the US population of this age and gender, it is essential that the elements used in exposure assessment be carefully measured, both to obtain baseline values in early pregnancy, and to assess the degree to which these values may vary across the course of pregnancy. It was intended to inform subsequent studies to test (with sufficient power) the possibility that psychosocial stressors in the workplace exert an effect on pregnancy. The work here represents a necessary first step in the ability to test these hypothesized effects, and will assist in determining whether newer models of the psychosocial parameters of stress in the workplace might be useful in measuring an association with adverse pregnancy outcomes. As well, this work represents an initial assessment of whether changes in measured parameters of stress, or distinct trajectories over time, occur during the course of pregnancy. Principal aims of the study were: (1) To explore the use of newer instruments measuring occupational psychosocial stressors in pregnant women; specifically using the Effort-Reward Imbalance (ERI) model, with comparison to, and possible combination of features with, the Demand-Control (DC) model. (2) To evaluate the psychometric properties of the ERI in pregnancy, including reliability, and content validity. (3) To evaluate the construct validity of the stress scales, to enable their use in measuring occupational psychosocial strain in pregnancy. (4) To evaluate the possibility that occupational psychosocial stressor levels in working women change across the unique time period represented by pregnancy, assessing the direction and magnitude of this change.
