Because the problem of homelessness has generated such attention and controversy, findings from studies of homeless populations are often received eagerly without appreciation of the significant biases inherent in surveys. Drawing on surveys of the homeless made in the 1980s, the authors review problems in sampling and in measurement of mental disorder. They suggest that within any one study researchers employ alternative sampling strategies and measures of mental disorder to facilitate comparison of results within and across studies.
由于无家可归问题引发了如此多的关注和争议，对无家可归人群的研究结果往往受到热切欢迎，却无人意识到调查中存在的重大偏差。作者借鉴20世纪80年代对无家可归者的调查，回顾了抽样和精神障碍测量方面的问题。他们建议，在任何一项研究中，研究人员应采用替代抽样策略和精神障碍测量方法，以便于在研究内部和不同研究之间比较结果。
