In 1986 a nationwide dental survey was carried out in the Netherlands. The aims of the study were to assess the prevalence of oral diseases, need and demand for dental care and oral selfcare in the Dutch population aged 15-74 yr. This paper describes the general sampling and analysis procedures to detect selectivity in the participation. Irregular dental attenders seemed to be underrepresented in the final sample. Poststratification was used to overcome this problem of selectivity.
1986年，荷兰开展了一项全国性的牙科调查。该研究的目的是评估15至74岁荷兰人群口腔疾病的患病率、牙科护理需求以及口腔自我护理情况。本文描述了用于检测参与过程中选择性的一般抽样和分析程序。在最终样本中，不定期看牙的人似乎代表性不足。采用事后分层法来克服这种选择性问题。
