Brief intervention for stress management and change in illness perception among hypertensive and normotensive workers: pilot study and protocol.

The objective of this study was to describe and evaluate the effects of a pilot intervention on perceived stress, knowledge about hypertension, and illness perception among hypertensive and normotensive workers. The intervention consisted of two group sessions performed in the workplace aiming to reduce stress, increase knowledge about hypertension, and explore the effect on illness perception. The sessions included clinical aspects of systemic arterial hypertension, illness perception and health behavior, and strategies for stress management. Workers from a petrochemical industry (19 hypertensive and 14 normotensive) participated in the study by answering a biosociodemographic questionnaire, the Brief Illness Perception Questionnaire, the Perceived Stress Scale, and a quiz with questions about hypertension. The measurements were collected at an initial meeting to gather the participants and 90 days after the intervention. There was a significant reduction in the perceived stress levels of both groups, in addition to an increase in the perception of personal control and illness coherence. Normotensive workers also increased their knowledge about hypertension, while hypertensive patients increased the perception that treatment could control the illness. In conclusion, the pilot intervention generated positive effects and can be considered a strategy of illness prevention for normotensive workers and control for hypertensive patients.
