title: Job demands, decisional control, and cardiovascular responses.
abstract: The demand-control model for coronary heart disease was tested using ambulatory blood pressure monitoring. Male patrol officers (N = 118) wore ambulatory blood pressure monitors during 1 of their day shifts with readings taken every 30 min. Following each reading, officers completed a questionnaire using a handheld computer. Significant interactions were obtained between job demands and decisional control for heart rate and pressure rate product such that both variables were highest under conditions of high demand and low control. Main effects were obtained for control such that diastolic blood pressure and mean arterial pressure were significantly higher under conditions of low control. These results support the demand-control model and emphasize the importance of psychological control in cardiovascular responses.
