Whereas it is well known that the ordering of items can influence research outcomes considerably, very little literature addresses instrument-order effects. Therefore, the aim of this study was to evaluate the effect of changing the administrative order of the Short-Form-12 (SF-12) and the Oral Health Impact Profile-49 (OHIP-49). It was hypothesized that if the SF-12 was administered first, the results would show poorer scores on the SF-12 subscales, as responses would not be restrained to only the oral impacts described by the OHIP-49. Using the Mann-Whitney U-test no significant instrument-order effects were found, except for the Psychological discomfort scale of the OHIP-49, where subjects scored higher when receiving the OHIP-49 first. However, the effect size was negligible (-0.08). These results suggest that no instrument-order effects occurred. Nonetheless, more research dealing with different instruments is needed. This study was performed within a dental setting and we recommend that instrument-order effects should be studied outside this domain.
众所周知，项目的排序会对研究结果产生相当大的影响，但很少有文献探讨问卷顺序效应。因此，本研究的目的是评估改变简短健康调查问卷12项版（SF - 12）和口腔健康影响程度量表49项版（OHIP - 49）施测顺序的影响。研究假设，如果先施测SF - 12，其分量表得分会更低，因为回答不会仅局限于OHIP - 49所描述的口腔影响。使用曼 - 惠特尼U检验，未发现显著的问卷顺序效应，OHIP - 49的心理不适分量表除外，在该分量表中，先接受OHIP - 49测试的受试者得分更高。然而，效应量可忽略不计（-0.08）。这些结果表明未出现问卷顺序效应。尽管如此，仍需要更多针对不同问卷的研究。本研究是在牙科环境中进行的，我们建议应在该领域之外研究问卷顺序效应。
