Forty smokers and 47 overweight individuals were recruited for a home correspondence program for either smoking cessation or weight loss. Participants were assigned to one of four programs for changing their respective health behaviors: (1) a home correspondence program conducted entirely by mail, (2) the mail program with supplemental financial contigency contracts tied to completion of written homework, (3) the correspondence programs supplemented both by homework contracts and by regular calls to a telephone answering system, and (4) a standard behavioral group program which acted as a comparison condition. Results showed that all three correspondence approaches produced significant changes in health behaviors equal to the changes experienced by participants in the standard group program. The implication of these findings for development of low cost programs for disease prevention are discussed.
40名吸烟者和47名超重者被招募参加一个家庭函授项目，该项目旨在帮助他们戒烟或减肥。参与者被分配到四个项目中的一个，以改变他们各自的健康行为：（1）一个完全通过邮件进行的家庭函授项目；（2）邮件项目加上与完成书面作业挂钩的补充财务应急合同；（3）函授项目既补充了作业合同，又定期致电电话应答系统；（4）一个标准的行为小组项目作为对照条件。结果显示，所有三种函授方法都使健康行为产生了显著变化，与标准小组项目中的参与者所经历的变化相当。本文讨论了这些发现对低成本疾病预防项目发展的启示。
