目的。本研究对健康促进研究试验中参与和不参与工作场所的类型和规模进行了考察。我们与随机抽取的符合条件的工作场所的代表进行了面对面和电话联系，这些工作场所被招募参加一项增加水果和蔬菜消费的研究试验。有250到2000名员工的工作场所和一个工作场所自助餐厅被招募。联络了81个工地。对符合条件的工作场所（N = 109）进行普查，形成招募基础，并随机选择工作场所（N = 81）亲自联系并要求参与研究。关于规模、工地类型和工地代表的资料是从一份私人编制的涵盖普吉特海湾地区的清单中获得的。通过简短的电话评估，项目的合格性包括在工作地点是否有一个现场自助餐厅。被联系的36个工地（44.5%）同意参与。工作场所的类型和规模在参与方面没有显著差异。可以招募工作场所参与研究试验。没有特定类型或规模的工作场所更有可能参与其中。制定随机化前的参与条件可以通过在随机化前确定对研究要求的依从性来减少随机化后的辍学率。
Purpose. In this study, the type and size of participating and nonparticipating worksites in a health promotion research trial were examined.Design. In-person and telephone contacts were made with representatives from a random sample of eligible worksites recruited to participate in a research trial to increase fruit and vegetable consumption.Setting. Worksites that had 250 to 2000 employees and a worksite cafeteria were recruited.Subjects. Eighty-one worksites were contacted.Measures. A census of eligible worksites (N = 109) formed the recruitment base, and a random selection of worksites (N = 81) was personally contacted and asked to participate in the research. Information on size, type of worksite, and a worksite representative was obtained from a privately compiled list covering the greater Puget Sound area. Eligibility for the project included the presence of an onsite cafeteria at the worksite as assessed by a brief telephone call.Results. Thirty-six of the contacted worksites (44.5%) agreed to participate. There were no significant differences in participation by type or size of worksite.Discussion. Worksites can be recruited to participate in research trials. No particular type or size of worksite is more likely to participate. Instituting pre-randomization participation conditions may reduce post-randomization dropout by ascertaining compliance with research requirements before randomization.
