This thesis analyses the sources of public evaluations of democratic regimes from a comparative perspective, a longitudinal perspective and with a case study of Spain. The main argument of the dissertation is that people's satisfaction with democracy (SWD) depends to a great degree on the quality of democratic processes and the institutional context. This conclusion does not deny the relevance of the well-documented relationship between the status of the economy and SWD. The importance of the economy is clearly confirmed by the current dissertation. Instead, this thesis argues that economic factors complement other political explanations. As will be shown, the long-term effects of the economy on SWD even depend on the quality of democratic processes and vice versa. This argument is presented in three related studies. In the first study, based on time-series cross-sectional (TSCS) data from 58 democracies between 1990 and 2012 and pooled surveys from the Comparative Study of Electoral Systems, I show that although electoral proportionality increases SWD, fractionalized party systems and coalition governments decrease SWD. In the second study, based on a twofold longitudinal panel analysis of the Spanish case between 1985 and 2015, I show that despite the negative consequences of prolonged economic crisis, political factors, most notably corruption, are equally relevant to explain the decline of SWD within this context. The third article, based on TSCS panel data from 61 democracies between 1980 and 2014, shows that economic performance and democratic quality are equally important explanations to account for both cross-national and cross-time differences in SWD and that both factors are interrelated in their effects on SWD.

We test the importance of responsiveness, performance and corruption to explain the evolution of political trust in Spain between 1997 and 2019. To this end, the study analyses two longitudinal datasets, namely, a repeated cross-sectional dataset from the Spanish samples of Eurobarometer and an individual-level panel survey conducted during a period of economic recovery in 2015. The study finds that perceptions about political corruption and responsiveness matter greatly in shaping political trust and to a lesser extent economic performance. Although the Great Recession is likely responsible for the sharp decline in trust towards political parties and the parliament between 2008 and 2012, the analysis suggests that trust in representative institutions remains low even after the Recession because of a series of devastating corruption incidents and a perceived lack of responsiveness of the political system. On the other hand, the study finds indications that trust in the judicial system might have been mainly affected by perceptions of corruption.

Consensual-pluralistic institutional features of representative democracies have traditionally been associated with satisfaction with democracy (SWD). However, more recent studies report contradictory results on the effects of some of these institutional determinants on SWD. This article confirms these puzzling findings by showing that electoral proportionality increases SWD while other pluralistic factors such as government fractionalization produce the opposite effect. We illustrate this duality of counteracting effects by expanding the number of cases under study to different regions of the world in a comprehensive time-series cross-sectional sample of 58 democracies between 1990 and 2012. In the second part of the paper, we are able to reconfirm these findings at the individual level by employing survey data from the Comparative Study of Electoral Systems.

Dyadic surveys aim to interview pairs of respondents, such as partners in a relationship. In dyadic surveys, it is often necessary to obtain the anchors' consent to contact their partners and invite them to a survey. If the survey is operated in self-administered modes, no interviewer is present to improve the consent rate, for example, by providing convincing arguments and additional information. To overcome the challenges posed by self-administered modes for dyadic surveys and to improve consent rates, it is important to identify aspects that positively influence the likelihood of anchors giving consent to contact their partners. Ideally, these aspects are in the hands of the researchers, such as the survey design and aspects of the questionnaire. Thus, in this study, we analyzed the relationship between anchors' survey experience and their willingness to consent to surveying their partners in self-administered modes. Based on data from the German Family Demography Panel Study (FReDA), we found that the anchors' perceptions of the questionnaire as "interesting" or "too personal" were related to consent rates. These relationships were consistent across different survey modes and devices. Effects of other aspects of the questionnaire, such as "important for science" and "diverse" varied between modes and devices. We concluded with practical recommendations for survey research and an outlook for future research.

Implementing innovations in surveys often results in uncertainty concerning how different design decisions will affect key performance indicators such as response rates, nonresponse bias, or survey costs. Thus, responsive survey designs have been developed to better cope with such situations. In the present study, we propose a responsive survey design that relies on experimentation in the earlier phases of the survey to decide between different design choices of which - prior to data collection - their impact on performance indicators is uncertain. We applied this design to the European Values Study 2017/2018 in Germany that advanced its general social survey-type design away from the traditional face-to-face mode to self-administered modes. These design changes resulted in uncertainty as to how different incentive strategies and mode choice sequences would affect response rates, nonresponse bias, and survey costs. We illustrate the application and operation of the proposed responsive survey design, as well as an efficiency issue that accompanies it. We also compare the performance of the responsive survey design to a traditional survey design that would have kept all design characteristics static during the field period.

Mixed-mode surveys are popular as they can save costs and maintain (or improve) response rates relative to single-mode surveys. Nevertheless, it is not yet clear how design decisions like survey mode or questionnaire length impact measurement quality. In this study, we compare measurement quality in an experiment of three distinct survey designs implemented in the German sample of the European Values Study: a single-mode face-to-face design, a mixed-mode mail/web design, and a shorter (matrix) questionnaire in the mixed-mode design. We compare measurement quality in different ways, including differences in distributions across several data quality indicators as well as equivalence testing over 140 items in 25 attitudinal scales. We find similar data quality across the survey designs, although the mixed-mode survey shows more item nonresponse compared to the single-mode survey. Using equivalence testing we find that most scales achieve metric equivalence and, to a lesser extent, scalar equivalence across the designs.

AbstractThis article discusses the current challenges of conducting a General Social Survey (GSS) in face-to-face mode and evaluates the alternative of fielding these surveys in self-administered mixed-mode (web, mail) instead. Based on data from Germany, it first illustrates the stark decline of participation in face-to-face surveys since 2002 and reports a strong increase in the cost of conducting these surveys over the same period. It then discusses the possibility of implementing GSS-type surveys in a self-administered design and reports results from a mode experiment implemented in the German part of the European Values Study (EVS) 2017/18. The results of the experiment indicate that self-administered mixed-mode surveys are a viable alternative for cross-sectional general population surveys in Germany; they shorten the fieldwork period and lead to higher response rates, while being more cost-efficient than face-to-face surveys. Despite the finding that the sample composition deviates from the general population in both modes, the face-to-face mode represents the population slightly better.

In Germany, the population registers with addresses of individuals can be used for address-based sampling. However, unlike countries with a centralized register, municipalities in Germany administer their registers themselves. This not only makes sampling for a nation­wide survey more costly and cumbersome but may also result in gaps in the gross sample, as selected municipalities may refuse to allow their registers to be used for sampling pur­poses. If substitute municipalities are not available, other sampling methods are required. The present study tested the feasibility of using the address database from Deutsche Post Direkt (ADB-DPD) as an alternative frame for address-based sampling in Germany. We simultaneously conducted two almost identical surveys in the German city of Mannheim with gross samples of equal size (N = 3,000). One sample was drawn from the city's popu­lation register, the other from the commercial ADB-DPD. Our findings suggest that the ADB-DPD performs well both in terms of survey response and up-to-dateness. Due to relatively low costs and the fast provision of addresses, the ADB-DPD could be particu­larly attractive for survey projects with limited budgets and tight schedules. However, these benefits come at considerable cost. First, the use of the ADB-DPD is limited to self-admin­istered surveys. More importantly, in the net sample of the DPD survey, women and young persons were considerably underrepresented. This indicates coverage issues about which DPD provided no further information. Based on our analyses, we offer practical insights into the feasibility of using the ADB-DPD for sampling purposes and suggest avenues for future research.

Self-administered mixed-mode surveys are increasingly used as an alternative to face-to-face surveys for collecting data from the general population. However, little is known about how decisions regarding the incentive scheme and the mode-choice design jointly affect key outcomes such as response rates, net sample composition, and survey costs. To study this, we drew a probability sample of the residential population of the city of Mannheim, Germany (N = 2,980) and randomly assigned target persons to one of four incentive schemes (€0, €1, or €2 prepaid incentive on first contact, and €2 delayed prepaid incentive) and one of two mode-choice designs (concurrent or sequential [web-push]). Our results indicate that small prepaid monetary incentives work better in concurrent than in sequential designs. Moreover, a €2 prepaid incentive in a concurrent design proved particularly successful for older target persons, probably reinforcing their sense of trust and reciprocity, while also fitting better with their survey-mode preferences. Finally, a €2 delayed prepaid incentive in a sequential design primarily motivated target persons aged under 50 years. This combination of incentive scheme and mode-choice design also proved to be most cost-effective in that age group. Based on our results, we recommend using sampling frame information on age to address different age groups with different combinations of incentive scheme and mode-choice design. This may help to maximize response rates, achieve a balanced net sample composition, and minimize survey costs.

Abstract
During the COVID-19 pandemic, many survey programs switched to self-administered modes of data collection, often offering respondents both web-based and paper-based questionnaires. However, there is little guidance as to when to offer which mode, especially when the aim is to recruit participants for a panel survey. This study examines the effectiveness of different mode-sequence designs by analyzing an experiment implemented in the recruitment wave of the German panel study "Family Research and Demographic Analysis." We randomly assigned 108,256 individuals aged 18–49 years to one of three mode-sequence-design conditions: concurrent, web-first including a paper-based questionnaire with the second reminder (web-first-2), and web-first including a paper-based questionnaire with the third reminder (web-first-3). A fourth, simulated group did not receive a paper-based questionnaire (web-only). We analyzed how different mode-sequence designs affected outcome rates, sample composition, response distributions, data quality, share of paper-based questionnaires, postage costs, number of postal mailings in the recruitment wave, and participation in the first regular wave. Our results show no differences in response distributions and small differences in sample composition across the four mode-sequence designs. As the web-first-2 and simulated web-only designs yielded comparatively good response and recruitment rates at reasonable costs, we recommend their use when surveying adults between 18 and 49 years old.

We test the importance of the three 'p factors' (performance, process and probity) to explain the evolution of political trust in Spain between 1997 and 2019. To this end, the study analyses two longitudinal datasets, namely, a repeated cross-sectional dataset from the Spanish samples of Eurobarometer and an individual-level panel survey conducted during a period of economic recovery in 2015. The study finds that perception about corruption and political process matter greatly in shaping political trust and to a lesser extent economic performance. Although the Great Recession is likely responsible for the sharp decline in trust towards political parties and the parliament between 2008 and 2012, the analysis suggests that trust in representative institutions remains low even after the Recession because of a series of devastating incidents regarding corruption and perceived shortcomings of the political process. In contrast, the study finds certain indications that trust in the judicial system might have been mainly affected by perceptions of corruption.
