Recent literature highlights the need for more effective recruitment and retention strategies in prevention research. This article reports an investigation of the effectiveness of two recruitment strategies for a family-focused substance abuse prevention study. The first strategy offered prospective participants two points at which they could make a decision about their level of involvement in the research project and required only a limited initial time commitment. The second strategy required an initial commitment to participate in all phases of the project. The investigation was conducted with 208 rural families participating in the pilot phase of a five-year prevention study. There were three primary findings. First, both strategies were effective, yielding higher recruitment rates than would be predicted from relevant literature. Second, the strategy requiring a limited time commitment showed significantly higher rates of recruitment into the pretest, but was associated with significantly lower posttest retention rates. Third, data trends emerged but there were no statistically significant differences between the two recruitment strategy groups across a range of intervention participation indicators.
近期文献强调了在预防研究中需要更有效的招募和留用策略。本文报告了一项针对一项以家庭为重点的药物滥用预防研究的两种招募策略有效性的调查。第一种策略为潜在参与者提供了两个时间点，让他们可以决定自己参与研究项目的程度，并且只需要有限的初始时间投入。第二种策略要求最初承诺参与项目的所有阶段。该调查是对参与一项为期五年预防研究试点阶段的208个农村家庭进行的。有三个主要发现。第一，两种策略都有效，招募率高于相关文献预测的水平。第二，要求有限时间投入的策略在前测中的招募率显著更高，但与后测中的留用率显著更低相关。第三，出现了数据趋势，但在一系列干预参与指标上，两个招募策略组之间没有统计学上的显著差异。
