Despite the methodological advantages of representative sampling, few researchers in the field of marital violence have employed random samples for laboratory assessments of couples. The current study tests the feasibility and sampling success of three recruitment methods: (a) random digit dialing, (b) directory-assisted recruitment, and (c) a hybrid method. The number of successful telephone contacts with couples does not differ across the three methods; most successful calls contact nonviolent couples. The sample recruited through all three methods does not appear to match the demographics of the calling area, and all methods require a high monetary and human resource investment.
尽管代表性抽样在方法上具有优势，但婚姻暴力领域中很少有研究人员采用随机样本对夫妻进行实验室评估。本研究测试了三种招募方法的可行性和抽样成功率：(a) 随机数字拨号，(b) 目录辅助招募，以及 (c) 混合方法。三种方法与夫妻成功进行电话联系的数量没有差异；大多数成功的电话联系到的是非暴力夫妻。通过所有三种方法招募的样本似乎与呼叫地区的人口统计数据不匹配，并且所有方法都需要大量的资金和人力资源投入。
