This study evaluates the feasibility of a nonquota, street-intercept survey method that utilized random selection of interview sites.
The street-intercept survey was compared with a random digit-dial telephone survey conducted in the same catchment area among African-American adults aged 18 or older.
The street-intercept survey's response rate was 80.2%; residence rate, 85.3%; interview completion rate, 97.9%; interference rate, 4.0%; and yield rate, 2.5 interviews per interviewer per hour. The street-intercept method produced more representative distributions of age and sex than the random-digit-dial survey.
The street-intercept method is a feasible alternative to traditional population survey methods and may provide better access to harder-to-reach segments of the urban population in a safe manner.
本研究评估一种采用随机选择访谈地点的非配额街头拦截调查方法的可行性。
将街头拦截调查与在同一集水区对18岁及以上非裔美国成年人进行的随机数字拨号电话调查进行比较。
街头拦截调查的回应率为80.2%；居住率为85.3%；访谈完成率为97.9%；干扰率为4.0%；产出率为每位访谈员每小时2.5次访谈。与随机数字拨号调查相比，街头拦截方法得出的年龄和性别分布更具代表性。
街头拦截方法是传统人口调查方法的一种可行替代方法，并且可能以安全的方式更好地接触城市人口中较难接触到的部分人群。
