Introduction

In an environment of declining survey response rates, decreased use of landline telephones, and rising costs of telephone and in-person surveys, political science researchers have increasingly turned to online surveys to measure public opinion. In light of the growing prevalence of online surveys in peer-reviewed journals, it is important to recognize the wide variation in their design and quality. In the most literal sense, an online survey simply refers to a particular mode of interviewing in which the respondent self-completes a questionnaire over the Internet, whether on a computer, tablet, or cell phone. However, conducting surveys online is far more complex than simply relocating an in-person or phone survey onto the Internet. Online surveys use a variety of different sampling designs, recruitment strategies, and implementation procedures, all of which have implications for data quality. Some online surveys use probability-based designs, such as those sampled from a known population list of e-mail addresses (e.g., a university or business). Multimode probability-based surveys are also increasingly common, such as samples drawn from address-based sampling frames in which online completion is encouraged but a telephone or mail completion option is also available. Because there is no sample frame from which to draw a random sample of e-mail addresses from the general population, however, most internet surveys use nonprobability designs, such as those in which respondents are recruited through website banner advertisements. Other nonprobability online surveys use samples from opt-in online panels, in which individuals agree to answer multiple surveys in exchange for money or other incentives. Here again, there is wide variation in design and quality. Online panel vendors differ as to whether and how they attempt to make a sample appear representative of a broader population, by using quotas, matching, and/or post-stratification weighting. They also vary in terms of their workload expectations, incentive structures, and panel management. In sum, the considerable heterogeneity in online surveys is too often overlooked. Given the discipline’s overall embrace of the method, making sense of this heterogeneity is essential to understanding how best to design and analyze online surveys and, ultimately, evaluate knowledge claims being made with the resulting data. Fortunately, research on online surveys constitutes a large and growing segment of the survey methodology literature. The purpose of this bibliography is to provide a resource for understanding the variation in methods and quality of online data collection, the relative advantages and disadvantages of using online surveys, and best practices for designing and analyzing online surveys.

General Overviews

It did not take long for the survey industry to catch up as more and more people went online toward the end of the 20th century—surveys were being conducted via e-mail as early as the 1980s (Callegaro, et al. 2015). Today, online surveys make up a significant portion of academic, business, and government survey work (Schaeffer and Dykema 2011). Although disparities in Internet access were initially viewed as a key challenge to online surveys, Internet use in the United States (and around the world) has risen steadily since the turn of the century, with nearly 90 percent of Americans having access to the Internet in 2018. With the growth in the adoption of Internet-enabled mobile devices, even traditionally harder to reach populations, such as minorities, those in rural areas, and older individuals, now have widespread access to the Internet. Nonetheless, there remains considerable debate about online survey methods, fueled by the wide variation in sampling design and implementation approaches. As a result, research on online surveys has occupied an increasingly large place in the survey methodology literature over the past two decades. This section identifies seminal texts on survey methodology that provide the necessary foundation for evaluating online surveys, as well as comprehensive reviews of the online survey research. General overviews and edited volumes—including Groves, et al. 2009; Krosnick, et al. 2015; and Wolf, et al. 2017—provide a history of survey research and guidance on the design, implementation, and evaluation of online surveys. Others focus specifically on evaluating data quality through the perspective of the total survey error approach, examining the multiple sources through which error can be introduced during the survey process (Biemer and Lyberg 2003, Weisberg 2009, Groves and Lyberg 2010). Couper 2000 and Tourangeau, et al. 2013 cover a wide range of topics specific to online surveys, including design strategies, implementation approaches, and differences between various types of online surveys.
