To investigate the relationship between potential explanatory factors (socio-economic factors and health) and non-response in two general population health interview surveys (face-to-face and telephone), and to compare the effects of the two interview modes on non-response patterns.
Data derives from The Danish Health Interview Survey 2000 (face-to-face interview) and The Funen County Health Survey 2000/2001 (telephone interview). Data on all invited individuals were obtained from administrative registers and linked to survey data at individual level. Multiple logistic regression analyses were used to examine associations between potential explanatory factors and non-response.
The overall response rate was higher in the face-to-face interview survey (74.5%) than in the telephone survey (69.2%). Refusal was the most common reason for non-response and the same factors were generally associated with non-response in both modes of interview. The non-response rate was high among persons with low socio-economic position. No significant associations between health and non-response were found.
Health status does not play a systematic role for non-response rates in health interview surveys, but the non-response rate is higher in lower socio-economic groups. Analyses of non-response should be performed to understand the implications of survey findings.
调查潜在解释因素（社会经济因素和健康）与两项一般人群健康访谈调查（面对面和电话）中的无应答之间的关系，并比较两种访谈模式对无应答模式的影响。
数据来自于 2000 年丹麦健康访谈调查（面对面访谈）和 2000/2001 年丰恩郡健康调查（电话访谈）。所有邀请对象的数据均来自行政登记，并与个人层面的调查数据相关联。采用多逻辑回归分析来检验潜在解释因素与无应答之间的关联。
面对面访谈调查的总体应答率（74.5%）高于电话调查（69.2%）。拒绝是无应答的最常见原因，两种访谈模式中通常存在与无应答相关的相同因素。社会经济地位较低的人群无应答率较高。健康状况与无应答之间无显著关联。
健康状况在健康访谈调查的无应答率中没有起到系统作用，但社会经济地位较低的人群无应答率较高。应进行无应答分析，以了解调查结果的影响。
