We describe survey results from a representative sample of 1,075 U. S. social network users who use Facebook as their primary network. Our results show a strong association between low engagement and privacy concern. Specifically, users who report concerns around sharing control, comprehension of sharing practices or general Facebook privacy concern, also(More)
This case study presents a critical analysis of microsurveys as a method for conducting user experience research. We focus specifically on Google Consumer Surveys (GCS) and analyze a combination of log data and GCSs run by the authors to investigate how they are used, who the respondents are, and the quality of the data. We find that such microsurveys can(More)
Surveys are a commonly used method within HCI research. While it initially appears easy and inexpensive to conduct surveys, overlooking key considerations in questionnaire design and the survey research process can yield skewed, biased, or entirely invalid survey results. Fortunately decades of academic research and analysis exist on optimizing the validity(More)
Change aversion is a natural response, which technology often exacerbates. Evolutionary changes can be subtle and occur over many generations. But Internet users must sometimes deal with sudden, significant product changes to applications they rely on and identify with. Despite the best intentions of designers and product managers, users often experience(More)
Online surveys are widely used in human-computer interaction (HCI) to gather feedback and measure satisfaction; at a glance many tools are available and the cost of conducting surveys appears low. However, there is a wide gap between quick-and-dirty surveys, and surveys that are properly planned, constructed, and analyzed. This course examines survey(More)
In this paper, we introduce a new construct for measuring individuals’ privacy-related beliefs and understandings, namely their perception of the frequency with which information about individuals is gathered and used by others for advertising purposes. We introduce a preliminary instrument for measuring this perception, called the Ad Practice Frequency(More)
With the rise of Web-based applications, it is both important and feasible for human-computer interaction practitioners to measure a product’s user experience. While quantifying user attitudes at a small scale has been heavily studied, in this industry case study, we detail best Happiness Tracking Surveys (HaTS) for collecting attitudinal data at a large(More)
