Methods and impact of health screening for hospital staff
通过随机对照试验，研究了两种健康筛查结果反馈方式对员工健康行为和信念的影响，发现详细反馈（含目标设定和书面合同）比简单信息反馈更能促进体重减轻和运动增加。
Abstract This study examines: (1) the impact of two methods of giving screening results on health behaviour and beliefs, evaluated in a randomized controlled trial. (2) The association between uptake of screening and health risk behaviours and beliefs. Two methods of feedback of screening results were given: simple informational feedback, and more extensive feedback, including target‐setting and a written contract. At six month follow‐up, those who received simple informational feedback had lost less weight and had increased their exercise less than those who received more extensive feedback. Attenders believed more strongly in the relationship between lifestyle and health, perceived themselves as less healthy than others and scored higher on the GHQ than staff who did not attend for screening. These results suggest that belief in the effectiveness of lifestyle change in promoting health, and anxiety about health, can influence uptake of screening. Second, the method of presenting screening results can influence the impact of screening on subsequent behaviour change.
