A quasi-experimental research design is used to evaluate Carolina Healthstyle, a health promotion project for South Carolina state employees. A 10% stratified random sample of employees was surveyed in the Spring of 1983 and again in 1984. Eighteen agencies were intervention agencies and the rest comparison that year. This article reports changes with simple before-after comparisons in the intervention agencies and matched pair analysis and randomized block designs to compare intervention and comparison agencies. Results are reported for smoking, exercise safety, nutrition, stress, and alcohol. Significant increases in exercise were found in both intervention and comparison agencies. The number of smokers decreased in intervention from 30%-26% with no change in comparison agencies. Safety practices changed at similar rates in both intervention and comparison groups. Consumption of chicken increased significantly only in the intervention agencies. Few other diet or stress changes were found. There were changes in alcohol consumption in intervention agencies only. The presence of the comparison group helps to separate the program effects from secular trends.
采用准实验研究设计来评估卡罗莱纳健康生活方式项目，这是一项针对南卡罗来纳州州政府雇员的健康促进项目。1983年春季对10%的分层随机抽样雇员进行了调查，并于1984年再次进行调查。当年有18个机构为干预机构，其余为对照机构。本文报告了干预机构中采用简单前后比较的变化情况，以及用于比较干预机构和对照机构的配对分析和随机区组设计。报告了吸烟、运动安全、营养、压力和饮酒方面的结果。干预机构和对照机构的运动情况均有显著增加。干预机构中吸烟者的比例从30%降至26%，对照机构则无变化。干预组和对照组的安全措施变化率相似。仅干预机构的鸡肉消费量显著增加。几乎未发现其他饮食或压力方面的变化。仅干预机构的饮酒情况有变化。对照组的存在有助于将项目效果与长期趋势区分开来。
