大多数工作场所都参与某种形式的健康促进方案，旨在改善工人的健康和降低医疗保健费用。虽然这些方案通常是通过研讨会和印刷材料相结合的方式提供的，但工作场所健康促进方案越来越多地通过互联网提供。 本研究的目的是评估一个基于网络的多媒体健康促进计划的工作场所，旨在改善饮食习惯，减少压力，增加体力活动的有效性。 采用随机对照试验设计，每组内的前后测比较，419名人力资源公司的员工被随机分配到基于Web的条件或提供相同主题的印刷材料的条件。所有受试者都在前测和后测时通过包含多种健康行为和态度指标的在线问卷进行评估。试验期为3个月。问卷资料的分析主要采用协方差分析和t检验。 两组的保留率都很好-基于Web的组为85%，打印组为87%。使用基于网络的程序的受试者在健康饮食态度（F1，415 = 7.104，P = 0.008）和饮食变化阶段（F1，408 = 6.487，P = 0.01）方面的表现明显优于印刷组，但在其他五项饮食措施上没有显著的组间差异。两组在大多数饮食指标上也显示出从测试前到测试后的改善，如显著性t检验所示。在基于网络的组中，剂量分析显示受试者访问该程序的次数对饮食自我效能的测量有显著影响（F2，203 = 5.270，P = 0.003）、对健康饮食的态度（F2，204 = 2.585，P = 0.045）和饮食变化阶段（F2，200 = 4.627，P = 0.005）。两组之间没有显着差异的压力或体力活动的措施，虽然t检验的前测后测的变化表明，两组改善了这些措施。在所有健康主题和总体评价方面，基于网络的组对节目材料的评分显著高于印刷组（F1，410 = 9.808，P = .002）。 这项基于网络的计划在改善饮食和营养方面比印刷材料更有效，但在减轻压力或增加体力活动方面并没有更有效。对基于网络的程序的较高评价表明，工人们更喜欢它而不是印刷材料。两组在所有健康主题上都显示出大量的前后测改善，尽管这种改善可能部分归因于霍桑效应。结果表明，多媒体网络为基础的程序可以提供健康促进材料的劳动力，特别是在饮食和营养领域的一种很有前途的手段。
Most work sites engage in some form of health promotion programming designed to improve worker health and reduce health care costs. Although these programs have typically been delivered through combinations of seminars and print materials, workplace health promotion programs are increasingly being delivered through the Internet. The purpose of this research was to evaluate the effectiveness of a Web-based multimedia health promotion program for the workplace, designed to improve dietary practices, reduce stress, and increase physical activity. Using a randomized controlled trial design with pretest-posttest comparisons within each group, 419 employees of a human resources company were randomly assigned to the Web-based condition or to a condition that provided print materials on the same topics. All subjects were assessed at pretest and posttest through an online questionnaire containing multiple measures of health behavior and attitudes. The test period was 3 months. Questionnaire data were analyzed mainly by analysis of covariance and t tests. Retention rates were good for both groups—85% for the Web-based group and 87% for the print group. Subjects using the Web-based program performed significantly better than the print group on Attitudes Toward a Healthful Diet (F1,415 = 7.104, P = .008) and Dietary Stage of Change (F1,408 = 6.487, P = .01), but there were no significant group differences on the five other dietary measures. Both groups also showed improvement from pretest to posttest on most dietary measures, as indicated by significant t tests. Within the Web-based group, dosage analyses showed significant effects of the number of times the subject accessed the program on measures of Dietary Self-Efficacy (F2,203 = 5.270, P = .003), Attitudes Toward a Healthful Diet (F2,204 = 2.585, P = .045), and Dietary Stage of Change (F2,200 = 4.627, P = .005). No significant differences were found between the two groups on measures of stress or physical activity, although t tests of pretest-posttest changes indicated that both groups improved on several of these measures. The Web-based group gave significantly higher ratings to the program materials than the print group on all health topics and in their overall evaluation (F1,410 = 9.808, P = .002). The Web-based program was more effective than print materials in producing improvements in the areas of diet and nutrition but was not more effective in reducing stress or increasing physical activity. The higher ratings given to the Web-based program suggest that workers preferred it to the print materials. Both groups showed numerous pretest-posttest improvements in all health topics, although such improvements might be attributable in part to a Hawthorne effect. Results suggest that a multimedia Web-based program can be a promising means of delivering health promotion material to the workforce, particularly in the area of diet and nutrition.
