本研究是第一个实证研究是否需要在网上调查领域损害可靠性和响应模式，因为参与者被迫回答所有项目可能会提供任意的答案。213名参与者完成了一项调查，包括六份问卷，测试个人和社会问题和看法。他们被随机分配到两个版本的调查：可选字段（N = 104）或必需字段（N = 109）。比较两个版本的Cronbach's alpha发现，所有问卷的信度值相同，除了躯体化，其中一个轻微的差异被发现。验证性因素分析表明，两个版本的因素结构没有差异，并没有发现差异贝叶斯t检验和Levene的方差齐性检验。研究结果表明，必填字段不会损害可靠性或改变响应模式，因此可以用于在线调查，以防止数据丢失。
The present study is the first to examine empirically whether required fields in online surveys impair reliability and response pattern, as participants forced to respond to all items may provide arbitrary answers. Two hundred and thirteen participants completed a survey consisting of six questionnaires testing personal and social issues and perceptions. They were randomly assigned to one of two versions of the survey: optional-fields (N = 104) or required-fields (N = 109). Comparison of the Cronbach's alpha of the two versions revealed identical reliability values for all questionnaires, save for somatization, where a minor difference was found. Confirmatory factor analysis showed no difference in the factor structure of the two versions, and no differences were found by Bayesian t-test and Levene's test for equality of variances. The findings suggest that required fields do not impair reliability or change the response pattern, and therefore can be used in online surveys to prevent missing data.
