In this paper, this model is combined with the unrelated question model (UQM) by Greenberg et al. (1969). The UQM is another survey technique that guarantees complete and objective anonymity to participants in order to achieve more valid survey results when asking sensitive questions (e.g., about drug use) . The resulting Poisson extension of the UQM (UQMP) is expected to yield valid estimations for how many participants engage in a researched sensitive behavior, and how regularly they do so. The performance of the UQMP was compared to the performance of the standard Poisson model, employing direct questions, in a survey on drinking and driving. While prevalence estimates differ greatly between the UQMP and the standard Poisson model, the results of both models indicate a high rate of drinking and driving among those German traffic participants who generally engage in this behavior. The different prevalence estimates could be due to the fact that some participants in online studies read instructions superficially, lowering the quality of results; we discuss possible causes for these problems and why the UQMP or similar approaches can be valuable nonetheless.  \nKeywords: Randomized Response Technique; Unrelated Question Model; survey research; time-constrained questions; prevalence curve; Poisson process  \n1 Introduction  \nIn survey research, one is often interested in obtaining prevalence estimates describing a certain target behavior. Prevalence estimates can be useful in many politically or socially important fields, such as for the assessment of public opinion or to evaluate the frequency of criminal or risky behavior like drug abuse. Oftentimes, these prevalence estimates are produced by posing yes/no questions that refer to a particular time frame, such as “Did you gamble in the past 12 months”(e.g., Andrie et al., 2019; Atzendorf et al., 2019; Beck et al., 2021; Birkel et al., 2022; Burr et al., 1989; Ferrante et al., 2012; Han et al., 2015; Isolauri & Laippala, 1995; Linton et al., 1998; McCabe et al., 2006 ; McKetin et al., 2006 ; amaz et al., 2014; Sawyer et al.,  \nCorresponding author: Benedikt Iberl, Eberhard Karls University of Tübingen, Tübingen, Germany (Email: [benedikt-jonas.iberl@uni-tuebingen.de](benedikt-jonas.iberl@uni-tuebingen.de))  \n2018; Virudachalam et al., 2014) . In this paper, we will call such questions time-constrained yes/no questions.  \nHowever, one might not only be interested in whether the concerning behavior has occurred within a certain timeframe, but also how often the behavior is shown. So, besides the information about whether someone was gambling in the last year, a researcher might be interested in the rate of this behavior (i.e., the average frequency of the concerning behavior per time unit) . To measure this rate, one could simply ask participants how often they have engaged in the behavior in question within a certain time frame (e.g.,“How often did you gamble in the past 12 months?”) . This kind of questioning technique is also widely used in prevalence research (e.g., Cullen et al., 2018; Miller et al., 2020; Molinaro et al., 2018; Seitz et al., 2020; Soga et al., 2021) ","cbCaik9o3ihnPSfU","https://ap.wps.com/l/cbCaik9o3ihnPSfU","pdf",704858,18,"English","# Introduction\n# Survey prevalence and time-constrained questioning\n## From yes/no prevalence to frequency rates\n## Participant effort and ambiguity in prevalence estimates","[{\"question\":\"What does the Poisson extension of the unrelated question model (UQMP) aim to estimate?\",\"answer\":\"UQMP is designed to estimate both how many participants engage in a sensitive behavior and how regularly they do so, while using anonymity-protecting questioning approaches.\"},{\"question\":\"How is UQMP evaluated in the paper?\",\"answer\":\"Its performance is compared with the standard Poisson model using direct questions in a survey on drinking and driving, focusing on differences in prevalence estimates.\"},{\"question\":\"Why might UQMP and the standard Poisson model yield different prevalence estimates?\",\"answer\":\"The paper discusses that online study participants may read instructions superficially, which can reduce result quality and lead to different prevalence estimates.\"}]","The Poisson Extension of the Unrelated Question Model - Improving Surveys with Time-Constrained Questions on Sensitive Topics | PDF",1789636874,45]
