The effects of health information in a worksite hypertension screening program.

Two studies assessed the potential impact of health education messages at worksite blood pressure screenings. The messages sought to: motivate hypertensives to enter or return to treatment, motivate normotensives to improve health habits and discourage inappropriate use of blood pressure screening by normotensives. A total of 473 participants in the two studies viewed slide/tape shows about blood pressure and/or health promotion. Individuals with elevated readings at screening viewed either a show containing standard blood pressure information or an experimental show which emphasized the asymptomatic nature of high blood pressure and which described some concrete strategies for coping with high blood pressure. In both studies, individuals with normal readings at screening viewed a standard show or an experimental show which emphasized coping strategies for preventing high blood pressure. In addition, in Study 2, some normotensive individuals viewed one of several experimental shows which focused on health promotion. Results indicate that the experimental programs were significantly more effective than the standard programs in achieving appropriate followup of screening results for both normotensives and hypertensives. Implications for worksite blood pressure screenings are discussed.
