One third of the Australian work force are immigrants. Relatively little is known about working conditions for specific migrant groups. The objectives of this paper are to describe and compare the sampling strategies used to recruit migrant workers from specific migrant groups working in Australia into a cross-sectional study designed to produce population estimates of workplace hazards and self-reported health.
Two cross sectional telephone surveys were conducted with immigrants currently working in Australia. Survey 1 used quota sampling from lists provided by a sample broker. Survey 2 used a combination of probability and non-probability sampling, including random sampling from telephone lists. Data from the surveys were weighted and comparisons made with unweighted data. While weighting adjusted for most differences across the sample sources, the likelihood of exposure to workplace hazards depended on exposure types and sampling strategies. We concluded that by using a combination of sampling strategies it is possible to recruit immigrants from specific migrant groups and provide a balanced view of working conditions, although no one strategy was best for all types of measures. Access to a robust sample source for migrants would enable a better perspective to migrant populations' working conditions.
澳大利亚劳动力中有三分之一是移民。对于特定移民群体的工作条件，人们了解得相对较少。本文的目的是描述和比较用于从在澳大利亚工作的特定移民群体中招募移民工人进入一项横断面研究的抽样策略，该研究旨在得出工作场所危害和自我报告健康状况的人群估计值。
对目前在澳大利亚工作的移民进行了两项横断面电话调查。调查1使用了样本经纪商提供的名单进行配额抽样。调查2使用了概率抽样和非概率抽样相结合的方法，包括从电话名单中随机抽样。对调查数据进行了加权处理，并与未加权数据进行了比较。虽然加权调整了样本来源之间的大多数差异，但接触工作场所危害的可能性取决于接触类型和抽样策略。我们得出的结论是，通过结合使用抽样策略，可以从特定移民群体中招募移民，并对工作条件提供一个平衡的看法，尽管没有一种策略对所有类型的测量都是最好的。获得一个强大的移民样本来源将有助于更好地了解移民群体的工作条件。
