Mood and cognition in pregnant workers

Thirty-eight working women, in their late second trimester or early third trimester of pregnancy, volunteered to fill out the Cognitive Failures Questionnaire and the UWIST Mood Adjective Checklist. In addition they provided information on the number of children they already had, the nature of their employment and their education level. The latter information was used to select a match for each pregnant worker from a larger sample of non-pregnant female workers. The results revealed no differences in the level of cognitive failures between the two groups. However, CFQ score was a better predictor of mood in the pregnant subjects, suggesting mood changes may be more closely related to perceived cognitive competency during pregnancy. The implications of this are discussed. With respect to mood sub-scales, non-pregnant workers scored higher on Energetic Arousal than pregnant workers. There were no differences on other mood sub-scales. It is argued that the cognitive efficiency of workers is not compromised by pregnancy but steps should be taken to ensure that work load is adjusted to take account of the self-reported reduced arousal that may arise.
