The effects of electronic performance monitoring (EPM) work management on mood disturbances and musculoskeletal discomfort were evaluated under three levels of data-entry task performance. EPM work management (i.e., performance monitoring and feedback) was used to induce compliance with data-entry performance standards of greater than or equal to 200 keystrokes per minute and less than or equal to six errors per minute. Forty-seven female office workers who had difficulty maintaining the data-entry speed standard were assigned at random to EPM work management or no EPM work management Participants in both work management conditions were divided into three keystroke performance groups (low, moderate, high). Self-ratings of mood disturbance and musculoskeletal discomfort were recorded at periodic intervals over three consecutive workdays. Regardless of the level of data-entry performance, the increase in perceived time pressure across the workdays was greater under EPM work management than under no EPM work management. Among workers who consistently failed to meet the performance standards (i.e., low and moderate performance), the increases in mood disturbances and musculoskeletal discomfort across the workdays were greater under EPM work management than under no EPM work management. These stress effects were more evident when keystroke rates were relatively close to the standard (moderate performance) than when they were far below the standard (low performance). The results suggest that EPM work management should be employed with performance standards that balance production requirements against the worker's skills and abilities.
