This paper investigates the effects on response and breakoff rates in Web surveys of e-mail invitation design elements including: subject line, estimated survey duration, and invitation length. The analysis is focused not only on the main effects, but also on an issue which has not yet been studied systematically: interaction effects between these design elements. A factorial complete block design Web experiment – among students, faculty, and administrative staff at the Higher School of Economics in Russia – varying the estimated length of the survey (10 vs. 20 minutes), subject line (formal “monitoring” vs. informal “help” request), and invitation length (short vs. long) was conducted. We discuss the results of the experiment and argue that we should not ignore interaction effects between design elements to understand response in Web surveys more thoroughly.
Since decades, cross-cultural psychology examines moral values using data from standardized surveys, assuming that values guide human behavior. We add to this literature by studying the link between moral values and various forms of prosocial behavior, using data from respondents of the sixth World Values Survey in Germany who participated in an online behavioral experiment. The experiment consists of a series of incentivized tasks and allows us to elaborate the association between survey-measured values and three facets of observed prosocial behavior. The evidence boils down to three findings. While (a) emancipative values relate to higher common pool contributions and (b) higher donations to charitable organizations, (c) secular values are linked with more productive and less protective investments. As these results conform to key theories and reach empirical significance in a major postindustrial nation, we conclude that we have important evidence at hand highlighting the potential of combined survey-experiment methods to establish value–behavior links that are otherwise inexplorable.
